With two drugs cleared by the U.S. FDA for Niemann-Pick disease type C (NPC) in less than seven days, Wall Street was pondering the differences between the compounds, given what’s known so far about each. Most recently, the FDA approved Intrabio Inc.’s Aqneursa (levacetylleucine) on its PDUFA date for the treatment of neurological manifestations of NPC in adults and pediatric patients weighing at least 15 kg, making Aqneursa the only approved stand-alone therapy indicated for NPC. On Sept. 20, Zevra Therapeutics Inc. won FDA clearance for Miplyffa (arimoclomol) as the first treatment for NPC.
Following the recent recommendation of its advisory committee, the U.S. FDA gave the nod to Zevra Therapeutics Inc.’s arimoclomol, a day ahead of its Sept. 21 PDUFA date, as the first treatment for Niemann-Pick disease type C (NPC), a rare genetic disease linked to progressive neurological symptoms that is almost always fatal. Branded Miplyffa, it is indicated for use in combination with enzyme inhibitor miglustat in adults and children, ages 2 and older.
As the Sept. 21 PDUFA date looms for arimoclomol from Zevra Therapeutics Inc. in Niemann-Pick type C (NPC), the U.S. FDA’s newly formed Genetic Metabolic Diseases Advisory Committee (GeMDAC) decided in favor of the drug.
Zevra Therapeutics Inc. will make its case Aug. 2 for its Niemann-Pick type C (NPC) candidate, arimoclomol, when the U.S. FDA’s Genetic Metabolic Diseases Advisory Committee (GeMDAC) meets for the first time.
After a rejection by the FDA in June, it looks like Orphazyme A/S is headed for disappointment in Europe too with arimoclomol for Niemann-Pick disease type C, a rare and potentially fatal inherited condition in which fat builds in tissues and organs. The Copenhagen-based company said it was summoned before experts to give an “oral explanation” about the drug, something that only occurs if the European Medicines Agency’s CHMP has developed major doubts during its review.
Shares in Orphazyme A/S cratered after the FDA rejected its arimoclomol for Niemann-Pick disease type C, a rare and potentially fatal inherited condition where fat builds in tissues and organs.
Despite two recent clinical trial failures, Orphazyme A/S’s arimoclomol is still on track for its June 17 PDUFA date in treating Niemann-Pick disease type C. The newest stumble is in the pivotal study of arimoclomol for treating amyotrophic lateral sclerosis (ALS) as it failed to hit its primary and secondary endpoints.
Top-line from Orphazyme A/S’ phase II/III trial of arimoclomol for treating inclusion body myositis, a muscle-wasting disease, failed to hit its primary and secondary endpoints. The data caused investors to pull back sharply as shares of Copenhagen-based Orphazyme (NASDAQ:ORPH) had dropped 28.97% on March 29 to close at $8.80 per share.
