Since being officially recognized as a distinct eating
disorder by the American Psychiatric Association in 2013, awareness of Binge
Eating Disorder (BED) has been slowly increasing, but it is currently only
properly diagnosed in a small proportion of cases. While BED is highly
prevalent, the number of patients receiving pharmacotherapy is severely limited
by a low diagnosis rate - estimated to be well under 5% of those living with BED
in 2017.
BED has quickly become a drug market ripe with opportunity
due to a growing diagnosed patient population - a trend that should be
encouragement enough for pharmaceutical companies to begin investing heavily in
BED drug development.
James Mather, Pharma Analyst at Publisher, comments:
"Over the next decade, we expect the increasing
awareness of BED among both physicians and the general public to drive an
increase in the diagnosis rate. The growing diagnosed population, coupled with
clinicians steadily becoming more comfortable with pharmacotherapy for BED,
will result in substantial growth in the BED pharmaceutical market. GlobalData
forecasts that the number of BED patients receiving drug therapy will more than
triple over the next decade."
The majority of BED clinical research is currently being
spearheaded by academic institutions and most is being funded by national
health organizations, as the current size of the drug-treated population
severely limits any return on investment. However, there are two notable exceptions:
Vyvanse (lisdexamfetamine dismesylate) was investigated in BED patients by
Shire, eventually being approved for BED by the FDA in 2015, and Sunovion’s
dasotraline is currently in Phase III clinical trials for BED. Only these
commercially funded trials have so far been large enough to provide sufficient
results regarding efficacy for regulatory bodies to take note and issue label
expansions to include BED.
Mather adds:
"While BED pharmacotherapy is currently dominated by
off-label therapies that mostly lack BED-specific clinical evidence, the
treatment landscape will shift towards products with significant clinical
evidence behind them in the coming years, headlined by the approval of
Sunovion’s dasotraline in 2020.”
