Nine years on from securing $3.84 million for a phase I clinical trial to test the formulation, with results showing it overcame side effects that had confounded its forerunner, the schizophrenia treatment Karxt met its PDUFA date Sept. 26 with no decision by midday. If approved, the fixed combination of xanomeline-trospium will be the first in a new drug class, and as a dual M1/M4 muscarinic agonist, the first new therapy to act via a novel mechanism for the serious psychiatric disorder in over 50 years.
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.
The U.S. FDA’s Oncologic Drugs Advisory Committee (ODAC) on Sept. 26 will take up a controversy that’s hardly new: whether approval of immune checkpoint inhibitor drugs should be restricted in accordance with PD-L1 expression.

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.
What comes down must go up seems to be the rule of thumb these days, even for U.S. FDA fees. The cost of using a priority review voucher (PRV) to shave four months off an FDA standard 10-month drug review has dropped drastically over the past several years. But come Oct. 1, biopharma companies will have to pay nearly 89% more than on the previous day to use a PRV.
Clearly frustrated by the U.S. FDA’s rejection of tradipitant to treat gastroparesis, Vanda Pharmaceuticals Inc. CEO Mihael Polymeropoulos said the agency is discouraging drug development for the serious gastric emptying condition for which there has been no new treatment in 40 years. The complete response letter (CRL) issued on the Sept. 18 PDUFA date for the neurokinin-1 receptor antagonist, which Vanda licensed from Eli Lilly and Co. in 2012, requested additional studies that the company said are not in line with the advice of experts in the field.
