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.
