**Instil Bio Announces Resumption of Clinical Trial of CoStAR-TIL Candidate ITIL-306 in Lung, Ovarian, and Renal Cancer**

–*Phase 1 trial of ITIL-306 in NSCLC, ovarian, and RCC re-opened to enrollment after voluntary pause*

–*Initial data readout for ITIL-306 expected in 2023* 

–*With recent reprioritization of clinical programs and corporate restructuring, company expects cash runway into 2025, excluding potential financing or other monetization of Tarzana manufacturing site*

**DALLAS, TX, January 9, 2023 (GLOBE NEWSWIRE)** Instil Bio, Inc. ("Instil" or the "Company") (NASDAQ: TIL), a clinical-stage biopharmaceutical company focused on developing next-generation tumor infiltrating lymphocyte, or TIL, therapies for the treatment of patients with cancer, today announced the resumption of its Phase 1 clinical trial of ITIL-306 for the treatment of non-small cell lung cancer (NSCLC), ovarian cancer, and renal cell carcinoma (RCC).

With the resumption of the ITIL-306 Phase 1 study, the Company expects to release initial safety, translational, and efficacy data from dose escalation cohorts at a medical conference in 2023. The trial was resumed after the implementation of additional quality safeguards designed to further protect the manufacturing process from potential contaminants in reagents from external suppliers.

Following its recent reprioritization of clinical programs and corporate restructuring, Instil expects its cash runway to extend into 2025, excluding the potential financing or other monetization of its Tarzana manufacturing site. Instil intends to provide further updates on its pre-clinical pipeline in 2023, including the potential to nominate additional CoStAR candidates and novel TIL technologies for clinical development.
