Why The Binge Eating Disorder Banner Ad Is Good Marketing




I noticed a new banner ad for Binge Eating Disorder in my Yahoo pages last night for the first time.  It is one of those sophisticated ads that becomes a video clip when you click on it.  The main message of the video clip is that "Binge Eating Disorder is a real medical disorder" and it provides a link to the web site bingeeatingdisorder.com.  If you go to that site and click on the health care professionals link, you are taken to what is essentially a massive infographic on binge eating disorder with descriptions of  what is known about the epidemiology and theory of B.E.D.  There is no mention of treatment or the specific FDA approved medication from this pharmaceutical company that has been approved for B.E.D.  My speculation is that is coming once the advertisers analyze their web traffic and see how well the ad campaign is accepted.  Specifically will there be the usual outcry that pharmaceutical companies are making up diagnoses in order to sell drugs and of course the evil psychiatrists that are involved.  If a lot of that blowback occurs it would be easy to cancel the campaign, take down the web site and either come up with another campaign or go with more traditional advertising to a much less politically adept audience, namely physicians through medical journals.  I admit, the brain graphic with a slice of pizza replacing the parietal lobe is eye catching.      

This ad allows me to make a couple of points.  The first is the reason that we have epidemics of addictive drugs.  The general process is an increase in availability and exposing more people to the drug.  We do not know the genotypes at risk but in general a significant part of the population will have euphorigenic responses to addictive drugs.  Wider availability generally equates to larger numbers of users and people at risk for addiction.  An example I like to use is growing up in northern Wisconsin.  Back in the 1970s, even though it was the hippie generation, the main exposure in remote areas was alcohol and marijuana.  Flash forward 40 years and now there is widespread availability of practically all drugs of abuse in rural areas, including intravenous heroin.  Anytime an addictive drug comes into the marketplace there is a risk that level of availability will lead to more addiction and complications of addiction.  In the case of the first amphetamine epidemic, it was marketing and general use for a number of disorders that did not respond to the medication and marketing products like benzedrine inhalers that could be easily abused.  In the end there were thousands of amphetamine containing products until all of them were moved to Schedule II and under much tighter regulation.

The second point is that the FDA clearly does an inadequate job of preventing addiction and complications of addiction.  There should be no doubt that the main objective of the FDA is to get pharmaceuticals out into the marketplace as soon as possible.  Although politicians like to grandstand on the idea that the FDA prevents the release of life-saving drugs or builds regulatory hurdles that lead to unnecessary expense there appears to be less and less evidence that is true.  Those same politicians seem to favor quicker release and less regulation.  It is fairly clear that the FDA has minimal scientific requirements.  The release of multiple new opioids during the time of an opioid epidemic of overdose deaths and against the recommendations of the Scientific Committee would be a case in point.  A further case in point is that none of these new opioid drugs is a unique compound.  They are all basically mixes and matches of old compounds in patentable dose sizes and various possibly tamper proof formulations.   Even as I type this note I am being informed that the FDA has accepted an application for reviewing a new drug that is a combination of extended release oxycodone and naltrexone.

The FDA clearly has a lax approach to potentially addictive compounds and they cannot depend on post marketing surveillance or their so-called REMS (Risk Evaluation and Mitigation Strategies).  A reasonable approach would be to use a gatekeeper strategy and monitor those physicians for complications from prescribing controlled substances.  Since agencies and regulators at all levels seem to believe that they can teach all physicians to prescribe controlled substances with an equal low level of skill, the time of the gatekeeper option is in the past.  The main FDA approach is post marketing surveillance or basically waiting to see what happens.  In the case of addictive drugs this is even a worse idea than with other risky medications.  The post marketing surveillance depends on reports from physicians, patients or other health care professionals.  Reporting a complication from a controlled substance is much less likely to happen for a number of reasons.  Physicians working in the addiction field may be working in settings where there is a higher standard for confidentiality than typical medical records.  Any time there is the potential interpretation of diversion or inappropriate prescribing reporting is less likely.  For these reasons post marketing surveillance is not a good approach to monitor a new pharmaceutical to see if it is being overprescribed and abused.

What is a good approach?  For decades there have been large databases that compile the prescriptions of all physician in the US.  This data was typically sold to pharmaceutical companies to gauge the success of their marketing efforts by the number of prescriptions written.  It is time that the FDA ran a database and looked at real numbers and trends in prescribing.  They would have first hand knowledge of how many new Vyvanse prescriptions were written for binge-eating disorders and where any potential prescription mills were located.  They could intervene before there was a years long or decades long problem.        

I conclude the Binge-Eating Ad is good advertising.  Someone once said that an addictive drug sells itself.  I think that is true in terms of the place that stimulants have in the collective consciousness of Americans.  They are seen as magical performance enhancing drugs that are good for whatever ails you.  I can see the pressure building in primary care clinics for Vyvanse prescriptions for Binge-Eating Disorder and patients expressing their severe disappointment if they hear their clinic will not prescribe it.  They will not understand that good advertising is not necessarily good medicine.

Creating demand for a medication with definite addictive potential seldom is.

Did The FDA Forget About America's First Amphetamine Epidemic?




That was the first thought I had when I read through the FDA release on the approval of Vyvanse for "binge-eating disorder".  I thought of the rotation I did on the Eating Disorder service at the University of Minnesota with some of the top experts in anorexia nervosa and bulimia.  In those days the residents admitted the patients and also rotated through the outpatient clinic where they saw new cases of eating disorders and developed treatment plans with the supervision of the attendings.  We talked about a lot of binge eating, since binge eating was a critical aspect of bulimic behavior.  ""Do you ever consume an amount of food large enough that it might be embarrassing if someone else found out?" and getting the details of that specific behavior was one of my standard interview questions.  It was clear that the binge eating of bulimia was a volume and rate task.  I would hear about large amounts of diet soda and popcorn being consumed in order to complete the cycle.

In the intervening 2 decades the only real changes was the addition of bulimia nervosa a composite of bulimic and anorexic behaviors.  That is until the advent of Binge-Eating Disorder in DSM-5.  In addition to a binge definition not much different from the one I used in 1984 eating an amount of food that is "definitely larger than what most people would ingest in the same period and similar circumstances" there is loss of control, and behavioral specifiers for rapidity, physical sensations, appetite, and psychological reactions to the binge eating.  Marked distress needs to occur and it cannot be part of another eating disorder.  The time specifier is that it needs to occur at least once a week for 3 months.  A summary of the FDA release about the indication states:

 “Binge eating can cause serious health problems and difficulties with work, home, and social life,” said Mitchell Mathis, M.D., director of the Division of Psychiatry Products in the FDA’s Center for Drug Evaluation and Research. “The approval of Vyvanse provides physicians and patients with an effective option to help curb episodes of binge eating."   

The DSM-5 has a point prevalence estimate of 1-1.5% in women with a peak in late adolescence and early adulthood.  That same section in the DSM-5 suggests that the course is variable:

"However, over longer-term follow-up, the symptoms of many individuals appear to diminish with or without treatment, although treatment clearly impacts outcome. Periods of remission longer than 1 year are associated with better long-term outcome." (DSM-5 p 351-352)

As far as I can tell, the evidence supporting the fast tracked application for Vyvanse is a typical 8 week clinical trial that looked at remission and reduction in binge eating rates in a multicenter study of 255 individuals (1).  Both the 50 and 70 mg doses were effective.  The publication of the research coincides fairly closely with the FDA release.  Searching through the FDA web site reveals no information about the opinion of a Scientific Committee and whether there was any consensus on the decision or concerns about the addictive potential of the drug.  

The pharmacology of the Vyvanse is interesting.  It is a prodrug - lisdexamfetamine that is a conjugate of lysine and amphetamine.  After it is absorbed into the circulation it is hydrolyzed to lysine and amphetamine.  There has always been some debate about whether this prodrug approach confers a decreased likelihood that the compound can be abused or used in an addictive manner.  Most addiction psychiatrists will tell you that it can and  the FDA approved package insert confirms the fact that it has significant abuse potential.   It is a Schedule II drug according to the DEA.

The lesson of the first amphetamine epidemic is that these drugs will be prescribed, to the point that there is very high demand and production of the drug.  Widespread health consequences were noted from overprescribing stimulants for questionable indications (weight loss, nasal congestion, depression, anxiety, psychosomatic complaints).  During the peak of this epidemic (1969) the total number of 10 mg amphetamine doses was about 25 million.  This was not exceeded until about 2005 and then only as a combination of amphetamine and methylphenidate.  As a psychiatry resident in the 1980s, I was still seeing obese people who had not lost a pound using very high doses of amphetamines.  The weight loss indication was subsequently banned in order to establish some limits on the overprescription of these compounds.  In other words, they were taking the drug because of an addiction rather than using it for any therapeutic effect.  It is clear that the prescription of controlled substances for diagnoses that are based on subjective findings is a recipe for epidemics of addictive drugs both in terms of total prescriptions, escalating use, and diversion.  Stimulant medications have the additional allure as possible performance enhancing drugs and are widely diverted for that purpose.

In that context, it would seem that the FDA would need to come up with a clear rationale for using a Schedule II drug to treat what may be a time limited disorder or a disorder that responds to non-medical therapies.  The complex nature of medications that have addictive potential needs to be recognized.  The prescription of these compounds takes more than rote knowledge. At the minimum there needs to be strict pharmacosurveillance on how this drug is prescribed and flags need to be in place for trends indicating that the prescriptions are starting to exceed the known prevalence of the disorder or the dose ranges are higher than recommended and/or combined with short acting stimulants.  These are all common problems seen in the overprescription of controlled substances.

Passive post marketing surveillance can no longer be considered a viable option for stopping the overprescription of controlled substances.   Waiting for intervention by law enforcement when problems have already begun is an approach from the 1960s.  In an era when data mining is commonplace, the FDA can do a lot more than get drugs out into the marketplace and wait to see what happens.

Supplementary 2:  Almost on cue I noticed the first banner ads for Binge-Eating Disorder today (2/12/2015).  It is advertised as a "real medical disorder" and is a brief informational film.  It has a spokesperson who talks about her experience with the disorder and refers the interested viewer to the company web site at BingeEatingDisorder.com.  It carefully coaches people in how to talk with their doctor.  The pharmaceutical company and manufacturer is listed at the bottom on the page.  The graphic of a pizza slice over a drawing of a brain varies in different views.  I don't know exactly what that means.  It suggests psychological therapies for B.E.D. and does not mention Vyvanse.  But let's face it - when people read there is a pill for their eating problem and it is an amphetamine - how many people will be asking for the psychological therapies?
