What’s Happening with a Generic Version of Vyvanse?
Vyvanse’s revenue projections in 2016 and 2017
Vyvanse, Shire’s (SHPG) key drug, is indicated for ADHD (attention-deficit/hyperactivity disorder) and moderate to severe BED (binge eating disorder) in adults.
The drug earned $1.7 billion in fiscal 2015, a 21% annual growth on a constant currency basis. Wall Street analysts expect the drug to further add $1.9 billion and $2.1 billion to Shire’s top line in fiscal 2016 and 2017, respectively.
Rising prescriptions of Vyvanse
In the fourth week of January 2016, Vyvanse prescriptions increased 16.8% on a weekly basis. Overall prescription growth for the adult ADHD market was 9.9% that week. Vyvanse has consistently outpaced the industry in terms of prescription volume growth.
In fiscal 2015, Vyvanse prescriptions increased 8%. Overall, prescriptions for adult ADHD in the United States increased 6% in 2015. To further increase prescriptions of Vyvanse, Shire is following a label expansion strategy.
Is a generic version of Vyvanse on the way?
The following companies have submitted ANDAs (Abbreviated New Drug Applications) with the FDA (U.S. Food and Drug Administration) for a generic version of Vyvanse:
- Amneal Pharmaceuticals
- Roxane Laboratories
- Sandoz, a subsidiary of Novartis (NVS)
- Mylan Pharmaceuticals, a subsidiary of Mylan (MYL)
- Actavis, which is now Allergan (AGN)
However, the FDA denied all the ANDAs and determined that Shire’s patent for Vyvanse is valid until 2023. Until the patent expires, a generic version of the drug can’t be launched.
To get exposure to Shire and at the same time control excessive company-specific risks, investors can choose to invest in the VanEck Vectors Pharmaceutical ETF (PPH). Shire accounts for 5.0% of the fund’s total holdings.
