Now that Avadel Pharmaceuticals plc has final U.S. FDA approval for its narcolepsy drug Lumryz, the company has priced the sodium oxybate formulation to match the cost of competitor Xywav from Jazz Pharmaceuticals plc. Avadel said it plans to charge $64.67 per gram for Lumryz. The annual cost based a 9-gram dose would be about $212,441 per patient. Three daily dose levels, 6 grams, 7.5 grams and 9 grams, were evaluated during a phase III study the final approval was based on.
Acting on its new promise to restore “rigorous enforcement” of the U.S. ban on unfair methods of competition, the FTC filed an amicus brief Nov. 10 supporting Avadel CNS Pharmaceuticals LLC’s motion to delist a Jazz Pharmaceuticals Inc. patent from the FDA’s Orange Book.
Investors clipped shares of Avadel Pharmaceuticals plc recently as anxieties rose over the application by Jazz Pharmaceuticals plc for a patent that relates to a once-nightly oxybate product that could threaten the prospects for Avadel’s FT-218.
