Catalyst Pharmaceuticals Announces Filing of Patent Infringement Actions Against Jacobus Pharmaceuticals and PantherRx
The lawsuit arises from Jacobus’ and PantherRx’s sales and marketing of Ruzurgi® (amifampridine, 10 mg). The lawsuit alleges that the Ruzurgi® product infringes the ‘893 patent when administered in accordance with its product labeling. The lawsuit seeks damages and injunctive relief to prevent further marketing of Ruzurgi® in violation of Catalyst’s patent rights.
"Catalyst has invested significant resources in neuromuscular drug discovery and in building an intellectual property portfolio that aids in the discovery and development of drugs for the treatment of rare neurodegenerative diseases that are without a safe and effective FDA approved therapy," said
Firdapse® (amifampridine) 10 mg tablets is an oral, nonspecific, voltage-dependent, potassium (K+) channel blocker that causes depolarization of the presynaptic membrane and slows or inhibits repolarization. This action results in the opening of slow voltage-dependent calcium (Ca2+) channels, allowing for a subsequent influx of Ca2+. In turn, it induces the exocytosis of synaptic vesicles containing Acetylcholine (ACh) to release more ACh into the synaptic cleft, enhancing neuromuscular transmission, and providing for improved muscle function.
Firdapse® is currently being evaluated in clinical trials for the treatment of MuSK-MG and SMA Type 3 and has received Orphan Drug Designation from the FDA for myasthenia gravis.
