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:

• In-licensed SYN-2510 and SYN-27M: In August 2024, SynBioTx, Inc., a wholly owned subsidiary of Instil, entered into a license and collaboration agreement with ImmuneOnco (HKEX:1541) for the exclusive global development and commercialization rights outside of Greater China of SYN-2510, a potentially best-in-class PD-L1xVEGF bispecific antibody, and SYN-27M, a next-generation ADCC-enhanced CTLA-4 antibody. SYN-2510 and SYN-27M have completed Phase 1a dose escalation studies in multiple solid tumor types in China, and ImmuneOnco is continuing patient enrollment in both programs to support dose optimization and dose expansion.

• Executed lease of our cell therapy manufacturing facility to AstraZeneca Pharmaceuticals LP: In July 2024, Instil reported the execution of a lease of its U.S. cell therapy manufacturing facility to AstraZeneca Pharmaceuticals LP. Under the terms of the agreement, initial base rent is greater than $7.5 million annually, and escalates at 3% per annum, with the tenant also required to pay certain operating expenses and tax expenses, subject to certain rent abatement in the first year of the 15-year lease term.

• Exploring further opportunities to in-license or acquire novel therapeutic candidates: Instil continues to explore further opportunities to in-license or otherwise acquire novel therapeutic candidates with first-in-class or best-in-class potential.
