Critical Success Factors for Launching Products with Orphan Drug Designation

The Orphan Drug Act (ODA) was passed in 1983 to financially incentivize pharmaceutical companies to develop drugs for rare diseases or conditions, defined as a disease or condition that affects less than 200,000 people in the US.1 The financial incentives offered by the ODA are substantial and include tax credits up to 50% of the qualified clinical testing expenses for the taxable year, waived Prescription Drug User Fee Act (PDUFA) user fees that may be upwards of $3 million in 2022, and an extended market exclusivity period of seven years after approval.2

A recent analysis found that receiving an orphan drug designation does, on average, positively impact companies’ value as measured through increases in stock price.3 Receiving an orphan drug designation does not impact the regulatory requirements to obtain marketing authorization; orphan drugs must go through the same FDA review process as other drugs.1,2,4 However, products that are granted an orphan drug designation may also pursue alternative approval processes including5,6:

  • Priority Review Designation — Shortens the application review to 6 months
  • Fast Track Designation — Facilitates the development and expedite review for treatment of a serious condition and fill an unmet need
  • Accelerated Approval Pathway — Allows for the approval based on a surrogate endpoint for the treatment of a serious condition that fills an unmet need
  • Breakthrough Therapy Designation — Expedited development and review of a drug that demonstrates substantial improvement over available therapy (see our recent paper “Breaking Through Launch Barriers: Critical Success Factors for Launch Products with Breakthrough Therapy Designation”)

Orphan drugs represent a sizable portion of the pharmaceutical marketplace. There have been 6,424 orphan drug designations granted since 1983, of which 1,085 products have received marketing approval from FDA for an orphan indication, with an average time from designation to approval of 5.3 years.7 From the 1990s to the 2010s, the number of designations granted has significantly increased by more than four-fold.8 Three therapeutic areas make up over half of all orphan drug designations: oncology, neurology, and infectious disease.7

Despite an attractive opportunity with multiple incentives for development and ability to address significant unmet needs in healthcare, orphan drugs also face unique challenges.
