Yale Psychiatry Grand Rounds: January 7, 2022

 .
  • 00:00Thank you very much, I appreciate it.
  • 00:03Very much the opportunity to
  • 00:06speak to folks about our work,
  • 00:08and I certainly appreciate everyone here.
  • 00:14Making the time to join us this morning
  • 00:18to hear about some of our work.
  • 00:21Again, I will provide an overview,
  • 00:24a balanced overview of
  • 00:27developments in recent advances.
  • 00:29Regarding binge eating disorder
  • 00:32and its treatment. I will try.
  • 00:36To be balanced along side that I
  • 00:39will also try to highlight a lot
  • 00:43of the work that our program here
  • 00:45at Yale has been working hard on.
  • 00:50The usual disclosures in past 24
  • 00:53months I've received royalties for
  • 00:56academic books from Guilford Press
  • 00:58and Taylor and Francis Publishers.
  • 01:00Our aims are to look at the prevalence of BD,
  • 01:06its distribution and associated
  • 01:08comorbidities,
  • 01:09talk a little bit about the
  • 01:10diagnosis of being D,
  • 01:11its clinical features,
  • 01:13and associated context that's relevant.
  • 01:15For case and clinical formulation.
  • 01:17Provide an overview of the
  • 01:21evidence base for psychological and
  • 01:24pharmacological interventions for DD.
  • 01:26And then focus a bit more on the recent
  • 01:28advances in effective treatments for being D.
  • 01:30As long as we, as,
  • 01:31along with recent advances in
  • 01:34methods for trying to gain a
  • 01:37better understanding of which
  • 01:39treatments work and for whom they
  • 01:42may work and ways to enhance them.
  • 01:46PD was included for the first time
  • 01:49as a research diagnosis in the DSM 4.
  • 01:52And then following a fair amount of research,
  • 01:55it was bumped up to a
  • 01:57formal category in the DSM.
  • 01:585 criteria are listed here.
  • 02:02The main piece that pay that's
  • 02:05really focused on perhaps too much.
  • 02:07I'll say a little bit about that a
  • 02:09little while with binge eating episodes.
  • 02:11This is a two part definition.
  • 02:13It's eating unusually large
  • 02:15quantities of food and I believe,
  • 02:19and I believe the empirical literature
  • 02:21suggests that the subjective sense of
  • 02:23loss of control that needs to accompany
  • 02:25it is actually the key feature.
  • 02:26In fact, the ICD has eliminated the need
  • 02:30for unusually large quantities of food,
  • 02:32and they focus more on a
  • 02:33subjective sense of control during.
  • 02:34Certain eating episodes,
  • 02:36but here on this side up on the
  • 02:39diagnosis requires large quantities
  • 02:41of food while experiencing a
  • 02:43subjective sense of loss of control.
  • 02:45Loss of control can be a
  • 02:48little vague for some people.
  • 02:50If you capture it as a
  • 02:51clinician and talking to them,
  • 02:53you'll see the light bulb go off.
  • 02:55If not,
  • 02:55you sometimes have to guide them
  • 02:57through it because they haven't
  • 02:58talked about this with other people
  • 03:00with the SM provides us with five
  • 03:03behavioral indicators for assessing
  • 03:04the loss of control and diagnosis.
  • 03:06Requires endorsement of at
  • 03:07least three of these.
  • 03:08These include things such as
  • 03:10eating much more rapidly than
  • 03:11usual during that episode,
  • 03:13eating large quantities of
  • 03:14food despite not being hungry,
  • 03:16eating until physically and
  • 03:18emotionally uncomfortable or painful.
  • 03:20Eating alone due to embarrassment about the
  • 03:22quantity or the nature of the eating itself,
  • 03:25and then feeling disgusted,
  • 03:27guilty, and depressed afterwards.
  • 03:28Those are strong words.
  • 03:29This is not the regret of having overeaten.
  • 03:32These are really intense emotional sequelae.
  • 03:35The diagnosis requires that there be
  • 03:37market distress about binge eating.
  • 03:39Interestingly, some people do.
  • 03:44Experience.
  • 03:46With those behavioral features
  • 03:47and the loss of control,
  • 03:49and are not particularly distressed about it.
  • 03:51The DSM would exclude those
  • 03:55people from the diagnosis.
  • 03:58The couple of exclusionary features.
  • 04:01There are no wait,
  • 04:02compensatory behaviors such as
  • 04:04the extreme restriction that
  • 04:05characterizes anorexia nervosa,
  • 04:07and there is the absence of a
  • 04:11variety of inappropriate purging
  • 04:13behaviors that characterize bleeding.
  • 04:16There no Rosa,
  • 04:17the frequency is requirements and
  • 04:20stipulations are that at least one
  • 04:23loss of control episode happened weekly
  • 04:26with the duration of at least three months.
  • 04:29This is a self monitoring record to
  • 04:31give you a quick idea from a clinical
  • 04:34perspective of what the eating
  • 04:36architecture topography may look like.
  • 04:39And it's not just so much the eating.
  • 04:41It's not so much the healthiness
  • 04:43and sometimes different eating
  • 04:44episodes can look rather similar.
  • 04:46It's when the loss of control
  • 04:48kicks in that we can categorize the
  • 04:50presence of a binge eating episode.
  • 04:53So this gentleman starts off
  • 04:54today at 7:00 o'clock,
  • 04:56through a drive-thru as a
  • 04:58toasted bagel with egg, sausage,
  • 04:59and cheese, a coffee roll,
  • 05:01large regular coffee.
  • 05:04Not a great nutritional start to the day,
  • 05:06but. Didn't concern this gentleman.
  • 05:13At 12:00 o'clock, another fast food
  • 05:15restaurant to beef burritos at beef,
  • 05:17a bean burrito and extra large soda goes
  • 05:19back to the office for Chocolate Chip
  • 05:22cookies and Work Lounge with his coworkers.
  • 05:24Gentleman arrives home and
  • 05:27he lives alone about 6:15.
  • 05:30Start thinking about ordering dinner,
  • 05:32ordering a pizza.
  • 05:34He proceeds as some chip dip and pretzels.
  • 05:38A few minutes later has
  • 05:39some crackers with cheese.
  • 05:40Has a half a bowl, leftover macaroni
  • 05:42while watching television awaits.
  • 05:43Green pizza, delivery,
  • 05:45pizza delivery finally comes on.
  • 05:47The gentleman has four
  • 05:48slices of sausage pizza,
  • 05:50a bag of chips and two sodas that's
  • 05:53experienced by him as his dinner.
  • 05:56Again, not a stellar nutritional.
  • 05:59Day, but you do see a bit of structure to
  • 06:02the day and that it's not continuous eating
  • 06:05like we sometimes see in some of these folks,
  • 06:08there are some eating episodes that are
  • 06:11roughly at mealtimes and so on and so forth.
  • 06:14An hour and a half later,
  • 06:15despite being.
  • 06:17Completely satiated.
  • 06:20Gentlemen,
  • 06:21thinking about some things against the field,
  • 06:24some distress goes back into the kitchen.
  • 06:26And proceeds to have another 4 slices of
  • 06:29the sausage pizza and finds bowl with the
  • 06:32leftover macaroni and cheese finishes.
  • 06:34It grabs 3 or 4 handfuls of chips
  • 06:37and reported literally stuffing
  • 06:40them in his mouth and then had a
  • 06:43leftover sandwich that was tucked
  • 06:45away on the side of the refrigerator.
  • 06:48During this episode he labeled
  • 06:50it as a binge eating episode.
  • 06:52He said he was eating.
  • 06:53He didn't know why he was eating.
  • 06:54He was eating rapidly.
  • 06:55He was.
  • 06:56Shoving the food in his mouth.
  • 06:58It was actually uncomfortable and he
  • 07:01felt utterly disgusted with himself.
  • 07:03If you look at the binge in the dinner,
  • 07:05just not really much of a difference there,
  • 07:07it is really the subjective
  • 07:09experience during the latter,
  • 07:10so this is not an issue around
  • 07:13overeating which most of us do
  • 07:15from time to time or frequently,
  • 07:17but rather a an episode that is very
  • 07:20salient and individuals who experience
  • 07:23these episodes are quite distressed by them.
  • 07:27How common is this?
  • 07:30Our colleagues and I.
  • 07:33Performed a epidemiologic analysis.
  • 07:38With this arc three which use DSM 5.
  • 07:43Criteria and we found that BD is
  • 07:45more prevalent than either anorexia
  • 07:47nervosa or bulimia nervosa.
  • 07:49Our estimate was a lifetime rate of .85%.
  • 07:53This rate is lower than previous studies.
  • 07:56This rate, however,
  • 07:58is consistent with the median
  • 08:00rates performed with a variety
  • 08:02of large scale European.
  • 08:04Studies.
  • 08:05Interestingly,
  • 08:06and importantly,
  • 08:08understanding the the distribution
  • 08:10is valuable for clinicians to help
  • 08:13recognize what potentially recognize
  • 08:15this problem occurs in men and women.
  • 08:18More women than men appear to
  • 08:20suffer from binge eating disorder,
  • 08:22but it does not show the market
  • 08:24gender distribution that we
  • 08:26see for anorexia nervosa.
  • 08:27In particular,
  • 08:28a BD occurs across ethnic and racial groups.
  • 08:31People of color appear to have
  • 08:35strikingly comparable rates.
  • 08:37As as wide as individuals,
  • 08:40BD occurs across all weight groups,
  • 08:43but is associated strongly with severe
  • 08:45obesity that we have a treatment confound
  • 08:47in the sense that in most clinical settings
  • 08:50most people with PD have coexisting obesity,
  • 08:54but at the national community level
  • 08:56it is found across all week groups.
  • 08:58But if you wait long enough, the excess
  • 09:01weight will eventually build the association.
  • 09:03With obesity is a strong one.
  • 09:06Large ratios there from three of the
  • 09:08major epidemiologic studies and National
  • 09:10comorbidity survey replication at a 4.9.
  • 09:14Odds ratio adjusted odds ratio.
  • 09:16The World Health Organization Mental
  • 09:18Health Study 6.6 and our analysis
  • 09:20with Nice start three point 4.6 again.
  • 09:24I emphasize that obesity and weight
  • 09:26fluctuation are most often the reasons
  • 09:28that lead people to seek treatment,
  • 09:30not to be D itself.
  • 09:33It is associated with elevated
  • 09:36risk psychiatric occurrences.
  • 09:37Nationally,
  • 09:38representative samples consistently find
  • 09:39that the majority in the vast majority,
  • 09:42nearly all patients have at least
  • 09:44one other psychiatric disorder.
  • 09:46The most common Co occurring disorders
  • 09:48are listed there in our in our analysis,
  • 09:5170% moved 68% Sud and 59% anxiety disorders.
  • 09:58These rates are fairly comparable
  • 10:00to other large scale studies.
  • 10:03This is sometimes viewed as are
  • 10:07the other eating disorders.
  • 10:08Unfortunately, as you know,
  • 10:10using unfortunate term as boutique disorders,
  • 10:12these disorders are associated with
  • 10:15high rates of chronicity and rather
  • 10:18concerning functional impairments.
  • 10:20Just as one example,
  • 10:22you're the prevalence rates that
  • 10:25we found for persons with eating
  • 10:28disorders and the adjusted odds ratios
  • 10:30for suicide attempts in persons
  • 10:33with binge eating disorder was 4.8.
  • 10:35Three,
  • 10:36that's a fairly concerning elevation
  • 10:40and risk of interest,
  • 10:42and the reasons are uncertain.
  • 10:44The onset of BD was significantly
  • 10:45more likely to proceed.
  • 10:47Suicide attempts in those
  • 10:48persons characterized with BD,
  • 10:50whereas people characterize,
  • 10:52without erexion impulsive blooming orvos,
  • 10:54it was about half and half.
  • 10:56Point being there are significant social,
  • 11:01psychosocial,
  • 11:02and functional impairments as well
  • 11:04as other kind of important health
  • 11:06indicators that these individuals
  • 11:08suffer from.
  • 11:09In terms of medical Co,
  • 11:11occurrences also has high elevated,
  • 11:14significantly elevated risk for a
  • 11:16variety of medical Cohen currencies.
  • 11:19First and foremost, obesity,
  • 11:21which I mentioned earlier,
  • 11:23but a variety of cardio,
  • 11:24metabolic problems,
  • 11:25various Crain,
  • 11:26chronic pain conditions and elevated
  • 11:29rates for a variety of these
  • 11:31medical conditions are elevated
  • 11:33even after adjusting for a variety
  • 11:35of socio demographic factors as
  • 11:37well As for adjustment for obesity.
  • 11:39The World Health Organization study
  • 11:42also found that the significant
  • 11:44associations were temporarily
  • 11:46primary be deleting or proceeding
  • 11:49subsequent medical comorbidities.
  • 11:51Something that does not come up
  • 11:53in the DSM or in a lot of kind of
  • 11:57clinical settings is a critically
  • 11:59important context that I would like
  • 12:02to highlight and that is the issue of
  • 12:05weight based stigma and negative biases.
  • 12:08To put it bluntly,
  • 12:10negative weight based stereotypes in
  • 12:12our society and similar societies
  • 12:14offer basic individuals with obesity
  • 12:17are widely viewed as lazy and lacking
  • 12:19in self discipline and in rural power.
  • 12:22Tests and and assessments
  • 12:25asking for explicit.
  • 12:27Views document this. Remarkably.
  • 12:33Stigmatising view that many of us
  • 12:36have studies that look at implicit
  • 12:40ways of getting at these attitudes.
  • 12:42Find the same.
  • 12:43I emphasize that such views exist
  • 12:45even among health care workers and
  • 12:47studies have also done documented
  • 12:50that these views are often common,
  • 12:52often present even in health care
  • 12:55workers with a specialty in the areas of
  • 12:58obesity and related metabolic problems.
  • 13:00So that's one problem.
  • 13:02The second problem is that such
  • 13:04views are often internalized
  • 13:06by the patients themselves.
  • 13:07Unlike some other discrimination
  • 13:10and stigmatizing experiences,
  • 13:11people with obesity often
  • 13:13buy into the same views,
  • 13:14and they begin to stigmatise themselves with
  • 13:18the same harsh language and harsh views.
  • 13:21So persons with obesity face.
  • 13:26Would be The Who have coexisting obesity and
  • 13:29come to us for help face weight based stigma.
  • 13:31They have long histories of being stigmatized
  • 13:34because of their size and their weight,
  • 13:36and they also have the added
  • 13:38shame about the binge eating.
  • 13:40So it's a kind of a double whammy,
  • 13:41so appreciation of the history.
  • 13:44There are many of our patients have with
  • 13:46weight based bias and discrimination
  • 13:48experiences is essential for effective care.
  • 13:51Language matters a great deal.
  • 13:53To belabor this point further,
  • 13:54this is an example.
  • 13:55This is not just bad manners.
  • 13:57This is not just we need
  • 13:59to be more respectful,
  • 14:00which I think we do.
  • 14:02This has medical consequences,
  • 14:04so just as an example analysis we
  • 14:07did with Denise Arc wave one and two,
  • 14:09we looked at weight based discrimination,
  • 14:11race based discrimination and sex
  • 14:13based discrimination and wave one and
  • 14:16associations with new cardiovascular
  • 14:21reports or incidents that we too.
  • 14:24Even after adjusting for
  • 14:26sociodemographic factors,
  • 14:27adjusting for BMI, adjusting for smoking,
  • 14:30alcohol, depression and stress,
  • 14:32we found that weight and race
  • 14:35based discrimination experiences
  • 14:37were associated with elevated odds
  • 14:40ratios for new cardiovascular.
  • 14:43Disease reports
  • 14:46adults who perceive weight
  • 14:48and racial discrimination and
  • 14:49multiple forms of discrimination.
  • 14:51The previous slide did not show the analysis.
  • 14:53We actually looked at the impacts of
  • 14:55multiple forms of discrimination may be
  • 14:57at heightened risk for certain types
  • 14:59of disease and with chronic medical
  • 15:01conditions among persons with obesity.
  • 15:03Clinically, we are starting
  • 15:04to see that stigma,
  • 15:05internalized weight biases are
  • 15:07associated with poor weight outcomes
  • 15:10and with reduced preventative care.
  • 15:12Many clinicians talk about poor
  • 15:14follow up and everything else.
  • 15:16A lot of patients when we interview
  • 15:18them and assess them overtime,
  • 15:20they often attribute the limited
  • 15:23follow-up to unfortunate and
  • 15:25stigmatising experiences.
  • 15:28Another aspect of binge eating disorder
  • 15:30that I wish to highlight and this,
  • 15:31I think is a major diagnostic
  • 15:34shortcoming in the DSM is the absence
  • 15:37of a body image criterion for BD body.
  • 15:41Image criteria are front Center for
  • 15:44Nexium and for bulimia nervosa.
  • 15:47We know that body image concerns are
  • 15:50much stronger in persons with BD than
  • 15:53in persons with obesity without BD.
  • 15:55Overvaluation of shape and weight
  • 15:58which is indistinct.
  • 16:00Construct this is not being unsatisfied
  • 16:02with one's weight and shape,
  • 16:03which in Western cultures is
  • 16:05merely normative. If you will.
  • 16:07This is a cognitive process by which
  • 16:11people defined define their primary
  • 16:13worth as a human being based on their
  • 16:16ability to control their weight or
  • 16:18shape or what their weight and shape
  • 16:20is viewed as and for whatever reason.
  • 16:23It was not a diagnostic criterion
  • 16:26or specifier for BDE to DSM 5.
  • 16:28A series of our studies in clinical.
  • 16:31Community convenience sample that
  • 16:34epidemiologic samples demonstrated
  • 16:36overvaluation was associated with
  • 16:38greater severity in a variety
  • 16:41of these adult samples.
  • 16:43We have done predictor analysis with
  • 16:45a variety of trials and we found
  • 16:48that its overvaluation is associated
  • 16:50with poor treatment outcomes.
  • 16:52The figure to the bottom there shows
  • 16:56rather a significant difference at
  • 16:58follow up between patients who had
  • 17:01overvaluation and higher levels
  • 17:03of valuation at baseline,
  • 17:05so it predicts poor outcomes.
  • 17:08It predicts and is associated with
  • 17:10poor functioning and variety of ways.
  • 17:12I feel it should be.
  • 17:13Diagnostic specifier or criterion.
  • 17:15But regardless of that,
  • 17:17in your case formulation,
  • 17:19it is an important thing to assess
  • 17:22and to understand very few moderators
  • 17:24of treatment have been identified
  • 17:26in the first study there that
  • 17:31JC P222 2012 paper we actually
  • 17:33found a very useful moderator
  • 17:35effect in that if you had
  • 17:37people high in overvaluation,
  • 17:39they did better in CBT,
  • 17:42and if you gave them
  • 17:44pharmacotherapy without CBT,
  • 17:46they did. Rather miserably
  • 17:51so let me belabor this a little bit further.
  • 17:56Then that that that kind of crawling
  • 17:59through the importance of overvaluation,
  • 18:01comes from our traditional
  • 18:03models of psychopathology.
  • 18:05A little bit about a complementary
  • 18:07approach which involves network analysis.
  • 18:09Uhm? Again, our traditional models
  • 18:12view symptoms as somehow emerging
  • 18:14from some sort of underlying entity.
  • 18:16If you, if you will network models,
  • 18:19you disorders and ever in
  • 18:21a in a very different way.
  • 18:23That there are these symptoms,
  • 18:25they're interconnected.
  • 18:27They influence one another.
  • 18:28They are maintained by one another
  • 18:30and they interact with one another.
  • 18:32If we are able to find ways to quantify.
  • 18:38The symptom interactions.
  • 18:41Within, you know some sort
  • 18:43of hypothetical construct.
  • 18:45We can then identify the
  • 18:46symptoms that are most central.
  • 18:48Again, the most central
  • 18:50being the key lingo there.
  • 18:52And the way that this is manifested
  • 18:54on the on the left side on
  • 18:55the blue you have the circles.
  • 18:57Those are symptoms.
  • 19:00Symptoms.
  • 19:02The lingo in in in that field is nodes and
  • 19:06then you have the various lines you see all
  • 19:09sorts of lines between all the symptoms.
  • 19:11The lines are called edges. In that system,
  • 19:13the thicker the edges the the stronger.
  • 19:18Interactions and and the connections.
  • 19:20So the most central symptoms in the
  • 19:22network are those that caused most
  • 19:25others or internal caused by most others.
  • 19:28If you look on the right,
  • 19:30the red you can see the rank ordering of
  • 19:33the centrality and overvaluation of shaping
  • 19:35and weight are the core symptoms of the.
  • 19:39So that's another.
  • 19:41Reason I think that overvaluation of
  • 19:44weight and shape is an important aspect.
  • 19:47So in terms of treatment needs is
  • 19:49a complicated construct and binge
  • 19:51eating behaviors. The disordered,
  • 19:52unhealthy eating outside the binge,
  • 19:54eating associated cognitive features,
  • 19:56the obesity, the medical comorbidities,
  • 19:59psychiatric comorbidity,
  • 20:00body image, in particular,
  • 20:01valuation of shape and weight and larger,
  • 20:04broader structural context that obesity,
  • 20:07stigma and discrimination experiences.
  • 20:13Well, a lot of people with BDC treatment
  • 20:16but they don't seek treatment for BDD.
  • 20:19Here when we looked at this and niece
  • 20:21are less than half people reported
  • 20:24every seeking treatment for BD.
  • 20:26When they do seek treat on that,
  • 20:28by the way, is particularly striking
  • 20:30for men and for people of color.
  • 20:33When they do seek treatments for other
  • 20:34things and when they are in treatment
  • 20:37for whether it's medical comorbidities
  • 20:38or psychiatric comorbidities,
  • 20:40they are rarely asked about their
  • 20:42binge eating. They're often.
  • 20:46Counseled or told or criticized for their
  • 20:50eating behaviors and their weight, perhaps,
  • 20:52but they're never asked about their body.
  • 20:55Image concerns and never asked about
  • 20:57any kind of binge eating patterns.
  • 20:59This large scale survey with over 20,000 US
  • 21:04adults found that of those with PD diagnosis.
  • 21:07Only three point.
  • 21:092% of them had been diagnosed by
  • 21:13any of their health care providers.
  • 21:16So it goes unrecognized.
  • 21:17Good news is this is something if
  • 21:20we can recognize that there are a
  • 21:22variety of treatment options available.
  • 21:24Start with pharmacol therapy.
  • 21:27Small RCT's have found that a variety
  • 21:30of medications are superior to placebo.
  • 21:32Food duesing binge eating,
  • 21:33at least over the short term.
  • 21:35The effects from an effect size perspective
  • 21:38are not particularly oppressive.
  • 21:40Except for topiramate.
  • 21:43Agents at the epileptic agent,
  • 21:45which reduces both binge eating
  • 21:46and weight over the short term.
  • 21:48Most of the medications taste tested to date,
  • 21:50have yielded minimal losses.
  • 21:53Sadly,
  • 21:53there's only one FDA approved
  • 21:56medication for BED.
  • 21:57Currently that's listex feta
  • 21:59mean it's a prodrug stimulant.
  • 22:01Those of you who work with
  • 22:03ADHD know that as Vyvanse,
  • 22:05this is the only FDA approved
  • 22:07medication for BD.
  • 22:08By the way,
  • 22:09there are no FDA approved medications
  • 22:11for anorexia nervosa and ferocity is
  • 22:13the only FDA approved medication for
  • 22:16bulimia nervosa going to present some
  • 22:18emerging findings for various medications.
  • 22:20And I should note that there's almost
  • 22:22no data existing regarding the longer
  • 22:24term effects of pharmacotherapy
  • 22:25and not lead up to some of the
  • 22:27studies that we're doing at power.
  • 22:28Now to try to address that,
  • 22:30the available studies,
  • 22:31mostly hours,
  • 22:32have found that seeking to be a
  • 22:35superior to medications over the long haul.
  • 22:37These are the.
  • 22:38This is the summary slide of
  • 22:41pivotal findings from the trials
  • 22:43from from this text that feta
  • 22:45mean that led to the FDA approval.
  • 22:48LDX at dosing of 50 to 70
  • 22:52milligrams over 12 week period.
  • 22:54Separated significantly from
  • 22:56placebo with pretty good effect.
  • 22:58Sizes .83 and higher.
  • 23:02And if you look at categorical remission,
  • 23:04rates are complete.
  • 23:06Abstinence from binge eating.
  • 23:08The remission rates were 36% and
  • 23:1140% versus 13% and 14% for placebo.
  • 23:19We also did a study out,
  • 23:21collaborated on study with Destro Lean.
  • 23:24This is a DNR inhibitor.
  • 23:27The design of the study was
  • 23:29almost identical to the LVX.
  • 23:33Pivotal studies one was a flexible dose
  • 23:38and it was superior to placebo for
  • 23:41reducing binge eating or remission.
  • 23:43Rate was 47% versus 21%.
  • 23:47A fixed dose follow-up study
  • 23:49found that 6 milligrams but not
  • 23:524 milligrams was superior to
  • 23:54placebo for reducing binge eating.
  • 23:57The remission rates at the categorical level
  • 23:59in the three doses were not significant.
  • 24:03The company, by the way,
  • 24:04has decided not to do additional
  • 24:06studies to pursue FDA approval.
  • 24:08In terms of psychological treatment,
  • 24:11a variety of focal manualized
  • 24:14treatments are available.
  • 24:15CBT interpersonal psychotherapy behavior,
  • 24:17weight loss and a lot of folks
  • 24:20have tried combining psychological
  • 24:22and pharmacological treatments.
  • 24:24Not going to show some of the
  • 24:26data that are weaker,
  • 24:27but I should highlight my clinical
  • 24:30perspective that there is no support
  • 24:32and I emphasize the no support
  • 24:34for the common clinical war about
  • 24:37integrating different treatments.
  • 24:40One of the major studies that was
  • 24:43published back in 2010 through the
  • 24:45multi site study Wilson Wolfley
  • 24:47in their sights alone Stanford.
  • 24:49They found interpersonal psychotherapy,
  • 24:51behavioral weight loss and cognitive
  • 24:53behavioral therapy produced
  • 24:54these effects which were roughly
  • 24:5660% remission rates for.
  • 24:58Call the remission rates.
  • 25:01Precaution compare cross study,
  • 25:02but we call it remission rates that I had
  • 25:05noted for the pharmacotherapy Albany studies.
  • 25:07So these were three different treatments.
  • 25:09They are conceptually behaviourally and
  • 25:12procedurally distinct focal treatments,
  • 25:14but they produce 60% roughly remission
  • 25:18rates and then after the these brief
  • 25:22treatments was particularly impressive.
  • 25:24Here are the durable effects,
  • 25:26particularly for interpersonal
  • 25:27psychotherapy and for cognitive
  • 25:29behavioral therapy where the the.
  • 25:31Benefits were very well
  • 25:34sustained for two years.
  • 25:37After the completion and
  • 25:40discontinuation of the treatments,
  • 25:41behavioral weight loss showed
  • 25:43a little bit less durability,
  • 25:46but still at 2 year follow up we
  • 25:48still had 40% of people who were.
  • 25:52Abstinent and that's nothing to sneeze about.
  • 25:55This was one of our.
  • 25:57Relatively early studies here at power.
  • 26:01That compare cognitive behavioral
  • 26:03and behavioral weight loss for BD.
  • 26:06A little bit of historical context
  • 26:09for this study and and some of this
  • 26:12is beginning to resurface again.
  • 26:14Which you know comes around
  • 26:16goes around I guess.
  • 26:17There for decades there were longstanding.
  • 26:22Controversial in fact,
  • 26:23rather heated claims by some
  • 26:26groups that behavioral weight
  • 26:28loss was not only ineffective,
  • 26:29but might actually exacerbate binge eating
  • 26:32and might exacerbate eating disorder.
  • 26:34Psychopathology and those individuals
  • 26:36who had excess weight or obesity
  • 26:39and also had binge eating.
  • 26:41Some of those models followed the
  • 26:43early restraint models of excessive
  • 26:45restrictive restraint leading to binge
  • 26:48eating and a bunch of groups took that.
  • 26:50And we're pretty passionate about.
  • 26:53As being a contraindicated treatment,
  • 26:56obesity feels I'm eating sort of
  • 26:57fields were not really on the same
  • 26:59page about this and I would get
  • 27:00very different messages depending
  • 27:01on which places I would go to,
  • 27:04present findings, and so forth.
  • 27:06I emphasize,
  • 27:07for those of you who do not know
  • 27:09that behavioral weight loss is
  • 27:11not a rigid or restrictive diet,
  • 27:13but it's rather a balanced,
  • 27:14moderate lifestyle approach to
  • 27:16eating and physical activity,
  • 27:18and it's delivered within the
  • 27:20context of a very solid learning
  • 27:22theory and behavioral therapy.
  • 27:25Platform, so we did this CBT versus
  • 27:28BWL versus a third condition
  • 27:30which was CBT followed by BW.
  • 27:33Well we maximize the horse race so to speak.
  • 27:37Given the historical context I provided and
  • 27:40here are the findings of post treatment.
  • 27:42Six month and 12 month follow
  • 27:44up on the left side for percent
  • 27:46limited on right side 4%.
  • 27:50BMI loss at 12 month follow-up
  • 27:53ITT remission rates were about
  • 27:5650% for CBT and 36% for BWL.
  • 28:02Mixed models analysis again.
  • 28:04ITT revealed a significant
  • 28:06advantage for CBT over BWL,
  • 28:08for reducing binge eating and mixed
  • 28:10models revealed a significant advantage
  • 28:13for BWL over CBT for reducing weight
  • 28:15at least through post treatment.
  • 28:18The failure of CBT to produce
  • 28:20any weight loss.
  • 28:21Or essentially no weight loss is a
  • 28:23consistent finding in our center and
  • 28:25centers nationally and internationally.
  • 28:27The findings we see here for BWL,
  • 28:29have been replicated a number of times since.
  • 28:35Before I go onto the new wave of studies,
  • 28:39one criticism that I often hear about
  • 28:42these kinds of manualized treatments is
  • 28:44that you can do them in your specialized
  • 28:47up sessional research clinics.
  • 28:49But how do they apply to real world clinics?
  • 28:53I don't buy that.
  • 28:55Regardless of what I buy here,
  • 28:56here at the data we did a study
  • 28:58with the Yale Hispanic Center
  • 29:00with the Yale Hispanic Clinic.
  • 29:02Excuse me in which we delivered manualized
  • 29:05behavioral weight loss treatment,
  • 29:07which was a hybrid of our behavioral
  • 29:09weight loss manual and the VP
  • 29:12the diabetes Prevention Program
  • 29:14behavioral Weight Loss Manual.
  • 29:15The treatments were delivered in
  • 29:18Spanish by the clinicians there.
  • 29:21The patients there have every
  • 29:24imaginable socio economic.
  • 29:26And educational disadvantage and you
  • 29:27see here a summary of the findings.
  • 29:30Completion rates were over 80%.
  • 29:33Patient did great.
  • 29:34The clinician bought into the treatment.
  • 29:36The patient brought into the treatment
  • 29:38and the outcomes are outstanding with
  • 29:40over 60% remission at post treatment
  • 29:42and six months after the completion
  • 29:45and discontinuation of treatment.
  • 29:4750% of the patients were still
  • 29:49absent from binge eating,
  • 29:50so those are significant durable outcomes.
  • 29:53My point here it is possible
  • 29:55to train and it is possible.
  • 29:56Disseminate these focal manualized
  • 29:59treatments to real-world settings.
  • 30:03Common question, well,
  • 30:04these this is complicated.
  • 30:06Should I take out the bazooka
  • 30:08and combine treatments with
  • 30:09more difficult patients?
  • 30:14So far the answer is no.
  • 30:16Adding pharmacotherapy to cognitive
  • 30:17behavioral therapy has failed to enhance
  • 30:20binge eating outcomes in six of the
  • 30:22seven relevant studies published to date.
  • 30:24Again, in a little while,
  • 30:25we'll see some of ongoing studies where
  • 30:27we have picked medications that have
  • 30:29a little bit more clinical rationale
  • 30:31are supposedly a bit more synergistic.
  • 30:33From a mechanistic perspective in a
  • 30:36story may change overtime, but so far,
  • 30:38based on the available data,
  • 30:40there is no noted.
  • 30:42Notable advantage to adding
  • 30:43pharmacotherapy to CBT for enhancing
  • 30:46the binge eating outcome.
  • 30:47Saying it goes for weight loss except for
  • 30:51the CORDINO study which found at Pyro mate,
  • 30:56significantly enhanced
  • 30:57short term weight loss.
  • 31:00Achievable CBT as well as enhanced the.
  • 31:07The the binge eating outcomes.
  • 31:09There's no, there's no support
  • 31:11for combining as a way to enhance
  • 31:14the behavioral treatments.
  • 31:16The flip side is not true.
  • 31:17We studied it produced that
  • 31:18in the other direction,
  • 31:19in which adding behavioral or
  • 31:21cognitive behavioral to the
  • 31:23pharmacotherapy did enhance both
  • 31:25retention and clinical outcomes.
  • 31:30Finally, to some of the
  • 31:31work that we're doing now.
  • 31:34Been trying and struggling with my
  • 31:37colleagues to find new designs and
  • 31:40RCT's that perhaps bear a greater
  • 31:43resemblance to treatments and
  • 31:45treatment approaches in real settings.
  • 31:48A lot of the RCT's reviewed
  • 31:51up until this point.
  • 31:53The basic question is which
  • 31:55treatment can help the most?
  • 31:57Or which treatment can
  • 31:59help the most patients.
  • 32:01A lot of work in the past
  • 32:02ten years in our field,
  • 32:04another field has looked at step care models.
  • 32:06These often consider scalable,
  • 32:09less costly methods.
  • 32:10Prior to moving on to more intensive
  • 32:13treatments when there is an insufficient
  • 32:16response, that's very logical.
  • 32:17It makes sense.
  • 32:18There are cost effectiveness
  • 32:19reasons for doing that.
  • 32:21They're scholarly reasons for doing that.
  • 32:23The the National Institute
  • 32:25of Clinical Excellence,
  • 32:26the Nice guidelines in the UK,
  • 32:29not very scholarly approach to guidelines.
  • 32:32I feel, in fact,
  • 32:34suggests that start with a guided self
  • 32:37help form of cognitive behavioral therapy.
  • 32:41And only if the patient
  • 32:43doesn't benefit enough,
  • 32:44you move on to a more intensive full
  • 32:48blown and more expensive treatment that
  • 32:50makes sense from a cost perspective.
  • 32:52It might make sense from a
  • 32:54broad community perspective.
  • 32:55Make sense from an availability
  • 32:57perspective there only so many
  • 32:59specialist clinicians on and on but.
  • 33:02As you'll see,
  • 33:03there are some potential glitches to that,
  • 33:05so one of the things we've been thinking
  • 33:08about are more complex models of care.
  • 33:10And instead of just the usual
  • 33:12stepped care approaches,
  • 33:13we've thought about some adaptive approaches,
  • 33:16and this comes out of analysis
  • 33:18that we've done with previous
  • 33:20trials where we have looked at
  • 33:22initial responses in patients,
  • 33:24so coral so called early rapid response.
  • 33:28As a way to guide subsequent clinical
  • 33:31decision making and this also fits
  • 33:33with an important development in
  • 33:35several fields so called smart designs
  • 33:38stands for sequential multiple
  • 33:40assignment randomization trials.
  • 33:44Early on, back in 2016,
  • 33:47we published a paper in which we
  • 33:49looked at the pattern of response
  • 33:51to CBT and to phylloxera teen
  • 33:54treatment for binge eating disorder.
  • 33:56And we found that the majority of
  • 33:59the treatment advances and benefits
  • 34:00happened in the first two weeks.
  • 34:05And then we did a variety of analysis
  • 34:08and we found that this rapid response
  • 34:11was highly predictive of who?
  • 34:16Remitted at the end of treatment.
  • 34:19But we also found that
  • 34:20the pattern was differed.
  • 34:22It was different for different treatment.
  • 34:23So if you did not have a rapid response.
  • 34:27Medication staying with the medication
  • 34:29did not have any added benefit.
  • 34:32If you didn't have an added.
  • 34:34If you didn't have a rapid response
  • 34:37to CBT and you stayed with CBT,
  • 34:40there was kind of a sleeper effect
  • 34:42and eventually you caught up.
  • 34:43We have since replicated that in a
  • 34:45variety of ways with a variety of
  • 34:47treatments with the CBT findings
  • 34:48being replicated over and over again.
  • 34:50But importantly,
  • 34:51we have found that for medication
  • 34:53treatments with various medications
  • 34:54that if you don't get a quick response.
  • 34:57Better off switching the person
  • 34:59sooner rather than later.
  • 35:00Most clinicians I think.
  • 35:01Well, let's let's wait a few more weeks.
  • 35:03Let's wait a few more months
  • 35:05that that I don't support that.
  • 35:07But interestingly, we did an analysis.
  • 35:10We did a couple of these.
  • 35:11In fact,
  • 35:12different trials with behavioral weight loss,
  • 35:14and we found an interesting finding.
  • 35:16If you had a rapid response
  • 35:18to behavioral weight loss.
  • 35:20That was highly predictive of of really
  • 35:23good longer term outcomes in both binge
  • 35:26eating remission and in weight loss.
  • 35:29Remember,
  • 35:29CBT does not produce weight loss.
  • 35:32So that.
  • 35:33Let us to this design.
  • 35:36This is one of our first
  • 35:38adaptive smart approaches to BD.
  • 35:40We start on the left side of the figure
  • 35:42with the first step care randomization.
  • 35:45We randomized people to either VWL
  • 35:47behavioral weight loss for six
  • 35:49months as the standard treatment,
  • 35:52the other condition we considered was
  • 35:54obviously CBT as you Norma CBT guy,
  • 35:56why did we pick BW?
  • 35:57Well, two pragmatic reasons.
  • 35:59BWL produces weight loss which
  • 36:00is an important clinical outcome
  • 36:02and and there are many many more.
  • 36:04Clinicians trained in doing behavioral
  • 36:06weight loss than they are in doing
  • 36:10cognitive behavioral therapy.
  • 36:11For better or for worse,
  • 36:12that was our thinking. This step?
  • 36:14Care randomization.
  • 36:15We start people with behavioral
  • 36:16weight loss for one month.
  • 36:17At the end of one month we stopped
  • 36:20and we see how people are doing.
  • 36:22If they are doing great,
  • 36:23we label those as as rapid responders.
  • 36:28We had an algorithm based on
  • 36:31several Roc analysis that we did
  • 36:33with different trials before and
  • 36:34we landed on a 70% reduction in
  • 36:36binge eating by the 4th week as our
  • 36:39marker for doing for doing well,
  • 36:41and if they weren't doing well.
  • 36:44We label them as non responders and
  • 36:46we switched treatment so if they
  • 36:47were doing well, it's not broken.
  • 36:49Don't fix it,
  • 36:49keep doing it and try to do it
  • 36:51better so we continue with the
  • 36:53beat up you well and we also
  • 36:55randomized them to an obesity.
  • 36:57I'm sorry.
  • 36:57Weight loss medication what to
  • 36:59a placebo and if they were not
  • 37:01doing well we randomized them
  • 37:02to an alternative treatment.
  • 37:03Cognitive behavioral therapy guided
  • 37:04self help with some people say treatment
  • 37:07of choice sort of good place to start.
  • 37:09And we also randomized them
  • 37:11to weight loss. Medication.
  • 37:14Or placebo in a double blind fashion.
  • 37:16And then we followed them up.
  • 37:19Our findings are summarized here.
  • 37:21We had remission rates in the two conditions,
  • 37:23which did not differ significantly
  • 37:26of 74% and 67%,
  • 37:27so we're getting a little bit better with
  • 37:30this behavioral weight loss treatment.
  • 37:33As we've seen this kind of
  • 37:35steady creeping factor,
  • 37:37so getting a little bit better each
  • 37:40time we've refined our treatments
  • 37:41based on some other lessons
  • 37:42we've learned from each trial.
  • 37:44And the right.
  • 37:46Slide shows the remission rates
  • 37:49within the different cells within
  • 37:51the different step care arms.
  • 37:54Adding the medication didn't
  • 37:55seem to do much with either.

  • 38:09and you see that the treatments did
  • 38:11not change did not differ either
  • 38:13in terms of the time course of
  • 38:15weight or the outcome at the end.
  • 38:16Six month treatments.
  • 38:18The right slide,
  • 38:20which is beyond today's scope
  • 38:22for good obsessional,
  • 38:23does look at some people who did.
  • 38:27Depending on which treatment they were in,
  • 38:28adding a weight loss medication did help.
  • 38:31Some of the weight loss,
  • 38:33which is fairly logical,
  • 38:34but overall it did lead to
  • 38:36a difference with the.
  • 38:37With the standard treatment.
  • 38:40Good news is 6 months,
  • 38:4212 months after the completion
  • 38:45of discontinuation of these.
  • 38:50These treatments,
  • 38:51the remission rates, were fairly well.
  • 38:54They're not at quite in that
  • 38:56same stratosphere of 67 and 74%,
  • 38:59but remission rates were still
  • 39:0245% and 41% at 12 months,
  • 39:05which is not differ significantly between
  • 39:07the standard and it's destep care.
  • 39:09Mixed models of binge eating frequency.
  • 39:11So binge eating frequency,
  • 39:13considered continuously.
  • 39:14We're also not significant between
  • 39:16the two treatment conditions and,
  • 39:18importantly, to drop off.
  • 39:19From post to 12 month follow-up
  • 39:22was not significant.
  • 39:2512 month follow up at percent
  • 39:27weight loss in the step care.
  • 39:30I was a little bit less than the
  • 39:33behavioral weight loss where we
  • 39:35actually hit a mean of 5% weight loss.
  • 39:39At 12 months after treatment,
  • 39:415% is often used as a marker in the
  • 39:43obesity field as potentially approaching
  • 39:45a clinically meaningful amount of weight.
  • 39:52We then designed this study.
  • 39:57Funded by NIH, in which we are finally
  • 40:01getting to the point where we have.
  • 40:04Different artillery available to us,
  • 40:06so we now have medications that seem
  • 40:09to potentially have greater benefit for
  • 40:11conceptually addressing the binge eating,
  • 40:14and more importantly,
  • 40:15they are a little bit more potent
  • 40:17for producing weight loss,
  • 40:19and that can be tolerated.
  • 40:21This is a study with naltrexone
  • 40:24bupropion combination medication
  • 40:25that's FDA approved for weight loss.
  • 40:28In this study, we had a balance
  • 40:31two by two factorial design, so.
  • 40:34You get behavioral weight loss,
  • 40:36yes or no.
  • 40:36You get naltrexone,
  • 40:37be appropriate or placebo in
  • 40:40double blind fashion that heals for
  • 40:43treatment conditions and the treatment
  • 40:45conditions went on for 16 weeks.
  • 40:47The behavioral weight loss by a
  • 40:50doctoral clinicians followed protocol
  • 40:52that had been well established.
  • 40:54Treatments with done well.
  • 40:57No,
  • 40:57I didn't hear 2 manuals and and and
  • 41:00so forth and then at the end of the
  • 41:03six weeks we conduct a post treatment
  • 41:05assessment and we see how they're doing.
  • 41:08If they responded to the initial
  • 41:10stage one treatments we?
  • 41:12Re randomize them to naltrexone placebo,
  • 41:16or to placebo.
  • 41:17This, as answer the very important question,
  • 41:20which, remarkably,
  • 41:21there is a dearth of data
  • 41:23available for clinicians.
  • 41:24Which is,
  • 41:24if you have a patient who
  • 41:26has responded to treatment.
  • 41:27Just keeping them or putting them on
  • 41:30a weight loss medication help them to
  • 41:35maintain their progress remarkably,
  • 41:37there's only one randomized control
  • 41:40test of a maintenance medication for BD,
  • 41:44and I was with LDX and LDX continuing
  • 41:47after the two treatment did
  • 41:49significantly reduce the chances of relapse,
  • 41:52so this is only the second such study.
  • 41:55We didn't have an exploratory arm
  • 41:56that what do you do with the people
  • 41:59who don't benefit to these two?
  • 42:00Presumably decent treatments.
  • 42:02One of the FDA approved medication and BWL.
  • 42:05I showed you all the data before.
  • 42:06Well here we switched them to CBT
  • 42:09here we learned from the previous.
  • 42:12Design where we switched them
  • 42:14to cognitive behavioral therapy.
  • 42:15Guided self help.
  • 42:16I was perhaps overly influenced by
  • 42:18Nice because I went to guided self
  • 42:20help but didn't seem to do enough.
  • 42:22So here we switch him to the full
  • 42:24blown CBT to see if that helps
  • 42:26the non responders.
  • 42:29Yeah, findings for you.
  • 42:30This is hot off the press.
  • 42:32We just did the analysis
  • 42:33over the last couple weeks.
  • 42:34Thank you relypsa.
  • 42:37We randomized 136 patients with PD
  • 42:40and obesity and here are the remission
  • 42:42rates at the end of treatment on
  • 42:45the left side in the blue box,
  • 42:47remission rates were significant for
  • 42:50behavioral weight loss and for naltrexone,
  • 42:52but the interaction was not significant.
  • 42:55When you consider the four cell design
  • 42:57in each of the active treatments were
  • 43:00significantly superior to placebo.
  • 43:02I do not show a graph here
  • 43:04for binge eating frequency,
  • 43:06but we saw the same rapid response
  • 43:09in binge eating frequency.
  • 43:11The decrease was significant for
  • 43:14being for behavioral weight loss.
  • 43:17It was not significant for naltrexone
  • 43:20bupropion nor was the interaction
  • 43:23significant the right slide.
  • 43:25So shows 5% weight loss categories.
  • 43:27The rate was the proportion meeting
  • 43:30this category was significant for BWL.
  • 43:33But not not trackson be propri
  • 43:36on and percent weight loss.
  • 43:38Considered continuously,
  • 43:38however,
  • 43:39was significant for BWL and for
  • 43:41now tracks don't be propri on as
  • 43:44well As for an interaction effect.
  • 43:45Again there wouldn't consider weight
  • 43:47loss as a percent continuously.
  • 43:50Each active treatment with
  • 43:53significantly superior to placebo.
  • 43:56We do not yet have the findings
  • 43:58were nearly done with the stage
  • 44:01two trial on whether behavioral
  • 44:03now trackson bupropion is superior
  • 44:05to placebo for preventing relapse.
  • 44:08Hopefully we can present that
  • 44:10down down the line,
  • 44:11but that's one of the
  • 44:12things we're looking at.
  • 44:13And we are also looking at ultrex
  • 44:16zone bupropion versus placebo
  • 44:17in a different study.
  • 44:19This is with our colleagues in.
  • 44:22Sherry Mackey's groups there,
  • 44:24that's a straight medication versus placebo,
  • 44:29designed with slightly more folks allocated
  • 44:32to the two medication conditions,
  • 44:34and she has embedded a nifty laboratory.
  • 44:40Eating paradigm to look at
  • 44:44behavioral and metabolic.
  • 44:46Correlate's,
  • 44:47and as moderators and potential
  • 44:49mediators have changed with
  • 44:51the medication treatment.
  • 44:55This is another ongoing smart design that
  • 44:58we have when we talk you through the.
  • 45:02Through the treatment. Come sell here,
  • 45:05this is a straight horse race from the
  • 45:08supposed leading treatments for BDL.
  • 45:10DX is the soul. Medication approved
  • 45:14by the FDA for binge eating disorder.
  • 45:17CBT is in in most guidelines and most
  • 45:20meta analysis and reviews considered
  • 45:23the leading psychological treatment
  • 45:25for BDD and we then did CBT plus LDX.
  • 45:30There is no control,
  • 45:32no placebo condition here as
  • 45:35both active treatments have.
  • 45:37Clearly demonstrated efficacy and
  • 45:39effectiveness in variety of setting.
  • 45:43The study here is how to
  • 45:46compare the two treatments.
  • 45:48The three treatments overtime.
  • 45:51Three month treatments.
  • 45:52That's the labeling for the LDX we
  • 45:55have manuals for CBT for 12 weeks,
  • 45:5820 weeks, 24 weeks and our effects.
  • 46:01Our comparable so the treatments
  • 46:03are nicely matched in that way.
  • 46:05At post treatment we assess again
  • 46:08a response based randomization.
  • 46:10If you were in either of the
  • 46:13LDX medication treatments,
  • 46:14you get re randomized.
  • 46:16If you were a responder to either LDX
  • 46:20or to placebo to see whether LDX.
  • 46:23Is superior to placebo
  • 46:24for preventing relapse.
  • 46:25This would be a replication of the
  • 46:27Hudson and all the sole report
  • 46:29in the literature that was in
  • 46:31JAMA Psychiatry suggesting that
  • 46:32the medicine prevents relapse.
  • 46:34If you were a non responder here,
  • 46:37we had much debate here with you.
  • 46:41Assign them to.
  • 46:42We took a cookie cutter approach.
  • 46:44We assign them to a different medication
  • 46:46that has a completely different.
  • 46:51Mechanism of action if you will.
  • 46:52So we chose naltrexone,
  • 46:55bupropion and our comparison condition
  • 46:58over the stage two is CBT that had
  • 47:01received CBT without any medication.
  • 47:04They received no further intervention,
  • 47:07and then we assess them at post
  • 47:09treatment and then at 6 and 12
  • 47:12months after this continually discuss
  • 47:14discontinuing the second stage treatments.
  • 47:16We do not have the findings for you.
  • 47:18As of yesterday.
  • 47:19I believe we had 84 people.
  • 47:21Randomized and nearly completed
  • 47:23treatment and stage one,
  • 47:26but we don't have those
  • 47:28outcomes to share with you yet.
  • 47:32Much of our work is evolved in
  • 47:35terms of trying to predict and
  • 47:37understand treatment outcomes.
  • 47:39One of the most common questions
  • 47:41that I get asked is, you know,
  • 47:44most of my patients have
  • 47:46comorbidity with treatments.
  • 47:47Should I use should I combine?
  • 47:48Should I add medications?
  • 47:50This is analysis that Janet
  • 47:53Whitaker and I did.
  • 47:54Australia this year.
  • 47:55Last year I should say.
  • 47:57And we examined psychiatric comorbidity
  • 47:59as a predictor and moderator or treatment
  • 48:02outcomes and an aggregated sample.
  • 48:04636 patients with BD who had received CBT,
  • 48:07behavioral weight loss medication,
  • 48:08plus therapy and controls
  • 48:10comorbidity predicted,
  • 48:11worst BD outcomes overall
  • 48:13and across treatments but did
  • 48:16not interact with treatments.
  • 48:17And it did not moderate binge
  • 48:20eating nor weight loss treatments.
  • 48:22So there's some evidence that if
  • 48:24you have a mood disorder you may do.
  • 48:26More poorly overall.
  • 48:29But that does not signal the
  • 48:31need for a combined treatment
  • 48:32or for a specific treatment.
  • 48:34I will remind you, however,
  • 48:36that this analysis,
  • 48:37the overall finding included
  • 48:38control conditions.
  • 48:39We do not find this kind of effect
  • 48:42from major depression or for
  • 48:44depression considered dimensionally.
  • 48:46Using a variety of rating scales as a
  • 48:49significant predictor or moderate are.
  • 48:50So that's I think a fairly definitive
  • 48:53answer to one of the most common
  • 48:55questions that is asked of me,
  • 48:57particularly by clinical psychiatrist.
  • 49:01Another way that we have tried
  • 49:05to predict treatment is here.
  • 49:07Earlier on I indicated that finding
  • 49:10reliable predictors of treatment and I just
  • 49:12showed you the the comorbidity findings,
  • 49:14which is a logical clinical thing to
  • 49:17look at to people comorbidity to worse.
  • 49:19Overall they do not and they certainly
  • 49:21don't point to a specific available
  • 49:23treatment that we have tested today.
  • 49:28A different way.
  • 49:31Again, we have found one reliable
  • 49:34treated predictor which is
  • 49:36actually a treatment process,
  • 49:37and that's rapid response,
  • 49:39which is why we built these smart
  • 49:41designs around that our reliable
  • 49:43predictor and the overvaluation of
  • 49:45shape and weight was the only other
  • 49:48thing a body image criterion that
  • 49:51predicted some outcomes in some trials,
  • 49:55and it actually moderated CBT
  • 49:58versus peroxide treatments.
  • 50:00Effects in a different trial,
  • 50:03but for the most part finding reliable
  • 50:05predictors have been hard, so.
  • 50:09A different way to do this is maybe
  • 50:14computers are smarter than us.
  • 50:16Clinician so we tried some
  • 50:18machine learning models.
  • 50:21And the answer is they didn't do
  • 50:24much better. But why did we do this?
  • 50:29A lot of field anxiety, some.
  • 50:33Depression, some dangerousness
  • 50:35domains people have been using
  • 50:37machine learning models to try
  • 50:40to predict what has is generally
  • 50:42viewed as hard to predict outcomes.
  • 50:44Machine learning is in contrast
  • 50:45to the way we've done our
  • 50:47predictor and moderator analysis,
  • 50:48where we have either theoretical or
  • 50:52clinical variables chosen based on.
  • 50:56Some kind of model that should be
  • 50:58associated with the treatments or
  • 51:00with the outcomes machine learning
  • 51:02rely on patterns in the data.
  • 51:04So you don't have these apriori
  • 51:08kinds of concepts.
  • 51:09Which might be theoretically smart,
  • 51:11or they may be biased in one point view,
  • 51:15but they learn patterns of data and then
  • 51:18they can generate and optimize models.
  • 51:22Are there ways to enhance
  • 51:23generalizability of those models by
  • 51:25doing a whole bunch of what they
  • 51:27refer to as cross validation attempts,
  • 51:29which in English means you can run a
  • 51:32whole bunch of different simulations?
  • 51:34And the other advantage to machine
  • 51:36learning is you can throw many
  • 51:39more variables into the models,
  • 51:41and in fact the more variables the
  • 51:43better because it just turns and turns
  • 51:45and turns and finds optimal combinations.
  • 51:48If there are so it actually benefits
  • 51:51from having many conditions.
  • 51:53This is not a panacea,
  • 51:55and I think the fields are trying
  • 51:58are finally coming around to
  • 51:59seeing that and some of the early.
  • 52:02You know great findings that some of
  • 52:04these machine learning models found
  • 52:06were because how they did some of the
  • 52:09simulations and most of the ones that
  • 52:12provided these great benefits for.
  • 52:16And we wrote about it a little bit
  • 52:18in in this paper in Psychological
  • 52:20Medicine published last year.
  • 52:22If you use certain types of simulations,
  • 52:24and you in particular certain
  • 52:28bootstrapping in methods such as
  • 52:30optimism corrected bootstrapping,
  • 52:32you can overinflate things.
  • 52:33So we just did this as
  • 52:36a math exercise awhile.
  • 52:38We also used the regular regression
  • 52:40approach to look at some of the clinical
  • 52:43variables based on our clinical models.
  • 52:45And machine model machine learning
  • 52:47models didn't have much advantage
  • 52:48over our regression models.
  • 52:50The area under the curve across the
  • 52:52different approaches was was poor to fair.
  • 52:57The the better way of doing these models,
  • 53:00I think, is with unbiased resampling
  • 53:02methods and they really had minimal
  • 53:04advantage over our traditional models.
  • 53:06So this is some of the ways in which
  • 53:08we you know we tried to think a
  • 53:10little bit outside the box and to
  • 53:12identify predictors of outcome which
  • 53:14would really help us come up with
  • 53:16better ways to target our treatments.
  • 53:18And and to know ahead of time who who
  • 53:20needs more attention and so forth.
  • 53:22I will note that the analysis
  • 53:24across different ways did converge
  • 53:26in a couple notable ways.
  • 53:28Rapid response again emerged
  • 53:30as a rather robust predictor.
  • 53:33And then importantly,
  • 53:35we bias internalization.
  • 53:38Which I highlighted early on in
  • 53:40my talk on my sofa box about being
  • 53:42respectful and polite to people.
  • 53:44Because they couldn't internalize
  • 53:46some of these negative attitudes.
  • 53:49Predicted poor binge eating and.
  • 53:53Eating disorder psychopathology outcomes.
  • 53:57Another approach that we tried
  • 53:58to use to kind of understand.
  • 54:03How treatments work.
  • 54:06Before I mentioned network analysis,
  • 54:08this is a network analysis.
  • 54:11It's performed this is hot off
  • 54:14the press and under review.
  • 54:16Reason to do this is.
  • 54:18A lot about predictor analysis.
  • 54:20Have looked at predicting intensities
  • 54:23or outcomes of the symptoms.
  • 54:26And this is an approach where we can
  • 54:28look at how does treatment impact
  • 54:30the way that symptoms are kind of
  • 54:34interconnected or related to one another.
  • 54:37And again you have.
  • 54:40If you look at the the left side,
  • 54:42the first blue.
  • 54:45Figure is what the network looks
  • 54:47at Pretreatment II blue figure
  • 54:49what the network looks like.
  • 54:50It's at post treatment and then this
  • 54:53the the final blue figure is what the
  • 54:56network looks like at post at 12 month.
  • 54:59Follow up the post and the follow up
  • 55:01were very similar to one another.
  • 55:03The indices for that are in those
  • 55:06squares there and to take home message
  • 55:09here is at pretreatment overvaluation.
  • 55:13Was the most central.
  • 55:18A feature. And remember,
  • 55:20I had highlighted that in a different
  • 55:23analysis earlier on in a talk,
  • 55:25so before treatment over valuation.
  • 55:29What is the most Australian feature and
  • 55:32you can see that in the right figure
  • 55:35for over valuation in the green dot?
  • 55:38At the end of treatment and at follow up.
  • 55:43This satisfaction had the highest centrality,
  • 55:46and you can see that in the right figure
  • 55:49towards the bottom of the two circles
  • 55:52that are way out towards the right.
  • 55:54So the way to interpret this
  • 55:57is not so much that we.
  • 56:00I reduced overvaluation of shape and
  • 56:02weight because you can't really say
  • 56:04that in a valid way given some of the
  • 56:08in's and outs of these analysis and
  • 56:09some of the concepts in the math.
  • 56:11And you also shouldn't say clinically
  • 56:13that we, oh, great job Grillo,
  • 56:16you, you and your team there.
  • 56:17You increase the satisfaction
  • 56:18with Wade and shape.
  • 56:19That's not what's happening here.
  • 56:21What's happening here?
  • 56:22Is the relationships among the symptoms
  • 56:24and the features of the disorder
  • 56:26and what I will highlight is if you
  • 56:29look at those squiggly lines there
  • 56:30and you match them up with network
  • 56:33analysis of similar constructs in
  • 56:35people without eating disorders,
  • 56:37they look rather similar.
  • 56:43Other ways in which we
  • 56:44are looking at treatment.
  • 56:45Let me just go back.
  • 56:48Is I mentioned? This study,
  • 56:52Doctor Potenza group and I have
  • 56:56a have an NIH grant grant in
  • 56:58which we are integrating F MRI.
  • 57:04Protocols before and after treatment,
  • 57:06along with neurocognitive testing
  • 57:07before and after treatment,
  • 57:08also is a way to look at both predictors,
  • 57:11but also potential moderators of treatment,
  • 57:15neurobiological and or psychiatric
  • 57:17moderators of treatment and by looking
  • 57:20at some of the changes that occur.
  • 57:24We will gain glimpses into potential
  • 57:27mediators and mechanisms of the change,
  • 57:30and that could also eventually guide him
  • 57:34more rational approach to ahead of time.
  • 57:37Telling a patient well.
  • 57:38Yeah, CBT and have LDX given
  • 57:42this this and this.
  • 57:43I would suggest this for you,
  • 57:45so that's another area that hopefully.
  • 57:48Will have the opportunity to report
  • 57:50to you at some point in time.
  • 57:54So in summary.
  • 57:58Please recognize the
  • 57:59broader context of obesity,
  • 58:01stigma and chain and shame and the
  • 58:04important body image constructs.
  • 58:06Big take home message for patients is
  • 58:08that there are effective treatments.
  • 58:10These treatments,
  • 58:10some of them can help very quickly.
  • 58:13On average our patients have
  • 58:14suffered in silence without coming
  • 58:16for treatment for over 10 years.
  • 58:17That's consistent with epidemiologic data
  • 58:19regarding long persistence and duration.
  • 58:21Of these problems when they go untreated,
  • 58:24our treatments often help
  • 58:25people within a month.
  • 58:27So there are effective treatments and
  • 58:29some can help quickly pharmacotherapy.
  • 58:31There's only one FDA approved
  • 58:33medication down the X,
  • 58:34or the others would be using off
  • 58:36label and presented some of that,
  • 58:37or regarding utility to
  • 58:39pirate made for some people,
  • 58:41even though that's a tricky medicine,
  • 58:42it's hard to get people up to 300,
  • 58:43four, 100 milligrams, which you have,
  • 58:45which is what you have to do.
  • 58:46But if you can,
  • 58:47does have some nice outcomes,
  • 58:48at least over the short term.
  • 58:50Psychological treatments include
  • 58:52several specific evidence based
  • 58:54focal manualized treatments,
  • 58:55most notably CBT, IPT,
  • 58:57and behavioral weight loss.
  • 58:59And what you see with those treatments
  • 59:01is that over 50% of the patients
  • 59:03seem to benefit a great deal,
  • 59:04and they have durable outcomes over
  • 59:06two to five years follow up and in
  • 59:09pharmacotherapy to CBT and behavioral
  • 59:10weight loss has generally failed to
  • 59:12enhance either with the medications
  • 59:14that have been tested to date,
  • 59:15but emerging research as
  • 59:17I presented from our lab,
  • 59:19is testing combination approved
  • 59:21approaches using new medications that,
  • 59:24from a mechanistic perspective,
  • 59:25should have a greater synergistic effect.
  • 59:28And we're working on coming up with
  • 59:30treatment research to integrate
  • 59:32methods to identify predictors,
  • 59:34moderators, and processes of change,
  • 59:36and we hope that this would lead
  • 59:38to more rational prescription
  • 59:40of truth treatments over time.
  • 59:43I am quite indebted to my colleagues
  • 59:46at power like to acknowledge Dr.
  • 59:49Lydecker and or my associate directors,
  • 59:53our faculty. These are our current faculty.
  • 59:56We have many faculty who have left us
  • 59:58for their own programs and leadership
  • 01:00:01positions here and elsewhere.
  • 01:00:03These are our current faculty and most
  • 01:00:06indebted to them for their collaborations.
  • 01:00:09We also have a number of study physicians
  • 01:00:13and coinvestigators gentek under Johnston,
  • 01:00:15Prof and Jorge Moreno.
  • 01:00:17And here we have our medical input
  • 01:00:20comes as represents psychiatry,
  • 01:00:23endocrinology and internal medicine so.
  • 01:00:26It's a very rich.
  • 01:00:30And stimulating.
  • 01:00:36Constant discussions and then
  • 01:00:38I'll postdoctoral associates.
  • 01:00:39These are our current Coast postdoctoral
  • 01:00:42associates who deliver the treatments
  • 01:00:45faithfully at a very high level.
  • 01:00:47Our retention rates are remarkable.
  • 01:00:49Both of completion treatments as well
  • 01:00:51As for the completion of retention,
  • 01:00:53follow-up assessments, and then,
  • 01:00:54through our pre doctoral
  • 01:00:56and research assistants,
  • 01:00:58who somehow keep the machinery
  • 01:01:00of the bazillions of pieces of.
  • 01:01:03Of of data in an organized way,
  • 01:01:05and we don't let people fall through
  • 01:01:07the cracks and we get everything
  • 01:01:09done that we need to get done
  • 01:01:11and we are most appreciative of
  • 01:01:13their efforts and finally to the
  • 01:01:16thousands of patients who have.
  • 01:01:21Come to us for help and have
  • 01:01:23been most generous of their time,
  • 01:01:25and they've had the courage to share
  • 01:01:27with us and reach out for help.
  • 01:01:29But then,
  • 01:01:30even long after the treatments are done,
  • 01:01:32they stay in touch with us and
  • 01:01:33how long follow-up studies to let
  • 01:01:35us know what's going well and
  • 01:01:36what's not going so well.
  • 01:01:38And that's the only way we can
  • 01:01:39get a little bit better at
  • 01:01:40doing what we're trying to do.
  • 01:01:42We need to get better,
  • 01:01:43so we really appreciate the giving
  • 01:01:45of these patients as they share these
  • 01:01:48very private and sensitive issues with us.
  • 01:01:50Before I take questions.
  • 01:01:51Put in a plug for one of our studies.
  • 01:01:54Any of you have in various
  • 01:01:56clinics and programs.
  • 01:01:57People who might have binge
  • 01:02:00eating disorder or concerns.
  • 01:02:03Here's one of our Flyers.
  • 01:02:04We thank YCCI for their excellence
  • 01:02:07in creating good Flyers.
  • 01:02:09The language we use there,
  • 01:02:10by the way, was carefully.
  • 01:02:12An obsession really thought out.
  • 01:02:14Given several studies that we did
  • 01:02:15in terms with our patient groups
  • 01:02:17and different settings and times in
  • 01:02:18the course of their illnesses to
  • 01:02:20figure out what kinds of language
  • 01:02:21in terms they find least offensive.
  • 01:02:24So thank you very much.
