Even as Alkermes plc works to resolve the complete response letter (CRL) sent by the FDA regarding ALKS-3831, labeling talks are underway for the compound, an oral therapy for schizophrenia and bipolar I disorder in adults. Regulators reviewed manufacturing records and said the Dublin-based firm needs to supply documents related to making the tablet’s coating at the Wilmington, Ohio, facility. No clinical or non-clinical concerns were raised, the firm said, and shares (NASDAQ:ALKS) hardly moved, closing Nov. 17 at $18.30, up 45 cents.
Opioid-related hazards with Alkermes plc’s combo drug ALKS-3831 – specifically, with the samidorphan element – and the significance of weight-gain reduction brought about by the tablet, which also includes olanzapine, became key topics in the joint meeting of the FDA’s Psychopharmacologic Drugs Advisory Committee and the Drug Safety and Risk Management Advisory Committee.
As expected, weight mitigation and opioid-related risks turned up as the main concerns in briefing documents for the joint advisory panel meeting Oct. 9 to mull the approvability of Alkermes plc’s ALKS-3831.
In a bid to expand its presence in CNS to a wider range of neurodegenerative diseases following a substantial restructuring last month, Alkermes plc has moved to acquire privately held neuronal epigenetics specialist Rodin Therapeutics Inc. for $100 million up front and up to $850 million in clinical, regulatory and commercial milestones.

Biogen will also pay Alkermes a royalty on worldwide sales of the product.
What the phase III multiple sclerosis (MS) win scored by Biogen Inc. and partner Alkermes plc might mean in the marketplace for diroximel fumarate – tested against their approved MS therapy Tecfidera (dimethyl fumarate) – became fodder for speculation as investors weighed the fine points of side-effect profiles and would-be reimbursement hitches.
