Beren’s Infantile Niemann-Pick disease Drug Review Extended
FDA has extended by three months its review timeline of a Beren Therapeutics NDA for adrabetadex for treating infantile-onset Niemann-Pick disease, Type C (NPC). The new user fee review action target date is 11/17.
The extension follows a 3/18 Beren response to an FDA information request that included updates and clarifications to existing data and supporting documentation. The agency classified the response as an NDA major amendment, which under FDA regulations extends the review period by three months.
The NDA was previously granted a priority review, and adrabetadex previously received orphan drug and breakthrough therapy designations.
Niemann-Pick disease, Type C is described as a rare, autosomal-recessive, severe, heterogeneous, neurodegenerative disorder caused by pathogenic variants in the NPC1 or NPC2 genes, leading to impaired intracellular cholesterol trafficking resulting in progressive neurological decline and premature mortality.
The company says clinical ( XXX delete capital C XXX)and nonclinical data demonstrate that adrabetadex directly targets the underlying pathophysiology of NPC by re-establishing intracellular cholesterol trafficking. The most common adverse events reported in clinical trials are hearing impairment (manageable with hearing aids when necessary) and post-dose fatigue and ataxia.
