DALLAS, Aug. 13, 2024 (GLOBE NEWSWIRE) -- Instil Bio, Inc. ("Instil") (NASDAQ:TIL), a clinical-stage biopharmaceutical company focused on developing a pipeline of novel therapies, today reported its second quarter 2024 financial results and provided a corporate update.

"We have expanded our pipeline with a pair of clinical-stage, potentially best-in-class therapeutics by in-licensing SYN-2510 and SYN-27M," said Bronson Crouch, CEO of Instil. "By executing a 15-year lease of our Tarzana cell therapy manufacturing facility, we have strengthened our financial foundation to support Instil's near-term clinical development of these assets."

Recent Highlights:
