Supernus Faces Generic Competition as Third Parties File ANDA Challenges for ADHD Drug Qelbree
- Supernus Pharmaceuticals received Paragraph IV Notice Letters from third parties who submitted Abbreviated New Drug Applications (ANDAs) for generic versions of Qelbree (viloxazine extended-release capsules) in 100, 150, and 200 mg strengths.
- The company plans to vigorously enforce its intellectual property rights, with six issued U.S. patents covering Qelbree that expire between September 2029 and April 2035.
- This generic challenge represents a significant threat to Supernus's ADHD treatment franchise, as generic competition could substantially impact future revenue streams for the CNS-focused biopharmaceutical company.
