Bristol Myers Squibb has terminated its $380 million capacity agreement with cell therapy manufacturer Cellares after determining the company's Cell Shuttle system could not meet requirements for commercial production of CAR-T therapy Breyanzi. Cellares will lay off approximately 100 employees on October 20, per a California WARN Act filing, affecting roles across engineering, marketing, recruitment, and software. The cuts come just 10 months after Cellares raised $257 million to scale toward commercial production. The layoffs signal continued volatility in the CDMO/cell therapy manufacturing sector, with ripple effects for specialized biotech talent demand.
