The observations noted in the CRL were specific to certain development batches of ALKS 3831. The company believes this issue has since been resolved and that sufficient data is available to address these observations. Alkermes is preparing those data for submission and plans to work closely with the Agency to resolve these items in a timely manner and complete labeling discussions for the application.
"We will continue to work closely with the Agency in an expeditious manner to support approval of ALKS 3831 for the treatment of schizophrenia and bipolar I disorder and believe we have a clear path to resolution. Importantly, there were no clinical issues identified in the CRL pertaining to ALKS 3831's efficacy or safety, and no new studies were requested for approval of the application," said
The NDA submission for ALKS 3831 was based on data from 27 clinical studies, including 18 studies evaluating ALKS 3831 and nine studies evaluating samidorphan alone, and pharmacokinetic bridging data comparing ALKS 3831 and ZYPREXA®. Throughout the clinical development program, ALKS 3831 demonstrated a consistent antipsychotic efficacy, safety, and tolerability profile in patients with schizophrenia.
Alkermes will host a conference call for analysts and investors on
