Dec. 21, 2023
By Karen Carey
Receiving a second complete response letter (CRL) from the U.S. FDA for gefapixant to treat refractory and unexplained chronic cough – an indication for which there are no approved treatments in the U.S., Merck & Co. Inc. said it is reviewing the agency’s feedback to determine the next steps, if any, for the oral selective P2X3 receptor antagonist.

Aldeyra already moving on new dry eye trial as it collects FDA CRL

By Jennifer Boggs

Alnylam pulls back on new Onpattro indication after surprise CRL

Oct. 9, 2023
By Mari Serebrov
Following an unexpected FDA complete response letter (CRL), Alnylam Pharmaceuticals Inc. said it will no longer pursue an expanded indication for Onpattro (patisiran) in the U.S. The RNAi therapeutic was approved in 2018 to treat polyneuropathy of hereditary transthyretin-mediated (ATTR) amyloidosis and seemed well on its way to snagging a second U.S. indication after the FDA’s Cardiovascular and Renal Drugs Advisory Committee voted 9-3 in September that the drug’s benefits outweighed its risks as a treatment for cardiomyopathy of ATTR amyloidosis. The FDA disagreed with the committee, saying in the CRL that patisiran’s clinical meaningfulness had not been established in the proposed indication.

Outlook says CRL for wet AMD is a surprise

Aug. 30, 2023
By Lee Landenberger
After hitting the safety and efficacy endpoints in a pivotal study of wet age-related macular degeneration (AMD), Outlook Therapeutics Inc.’s CEO said he had not expected to receive a complete response letter (CRL) from the U.S. FDA. The BLA for ONS-5010 (bevacizumab-vikg) now is on hold, the company said, because the agency said chemistry, manufacturing, and controls management problems were getting in the way, along with “open observations from pre-approval manufacturing inspections, and a lack of substantial evidence.”

Galera receives a CRL for its cancer treatment

Aug. 10, 2023
By Lee Landenberger
A complete response letter (CRL) from the U.S. FDA for GC-4419 (avasopasem) is causing Galera Therapeutics Inc. to dramatically change course to survive, with the company laying off about 70% of its workforce. That layoff, which will reach across several company departments, is designed to extend the cash runway into the second quarter of 2024. The adjustment comes after Galera expanded its commercial leadership in May to prep for a potential launch of avasopasem before the end of 2023.

Sage’s Zurzuvae approval and CRL roil the company and its stock

Aug. 7, 2023
By Lee Landenberger
Despite the U.S. FDA’s approval of Sage Therapeutics Inc.’s priority NDA for postpartum depression, the accompanying complete response letter (CRL) for major depressive disorder has undercut the company’s plans. Withholding the approval for MDD slices away a huge amount of the potential market for Sage and its collaborator, Biogen Inc.

Immunitybio’s bladder cancer candidate hit with a CRL

May 11, 2023
By Lee Landenberger
The U.S. FDA issued a complete response letter regarding the BLA for Immunitybio Inc.’s bladder cancer treatment, N-803 (Anktiva), halting the drug’s development and slicing the stock value in half. The problems stem from the FDA’s pre-license inspection of Immunitybio’s third-party contract manufacturing organizations, the company said. It said the FDA also had recommendations for specific chemistry, manufacturing and controls issues and assays that needed to be resolved before the BLA can be approved.
