DALLAS, March 07, 2022 (GLOBE NEWSWIRE) -- Instil Bio, Inc. (“Instil”) (NASDAQ: TIL), a clinical-stage biopharmaceutical company focused on developing tumor infiltrating lymphocyte, or TIL, therapies for the treatment of patients with cancer, today reported its fourth quarter and year end 2021 financial results and provided a corporate update.

“I am pleased with our progress in establishing our operational capabilities and initiating a clinical study in our first year as a public company,” said Bronson Crouch, Chief Executive Officer of Instil. “With the DELTA-1 Phase 2 trial of ITIL-168 underway and continued expansion of our manufacturing capabilities in both the United Kingdom and the United States, we continue to develop our platform to deliver cell therapies to patients. In 2022, we look forward to the opportunity to expand the targeted patient population for receiving our therapies in multiple indications with ITIL-168 and ITIL-306."

2021 Highlights and Anticipated Milestones:

  • Enrollment Ongoing in DELTA-1: Instil is enrolling patients in DELTA-1, a global Phase 2 clinical trial of ITIL-168 with registrational intent in patients with advanced melanoma whose disease has progressed following PD-1 inhibitor therapy and, if BRAF-mutated, targeted therapy. Instil expects top-line safety and efficacy data in 2023 which could potentially support BLA submission and a European Medicines Agency marketing authorization application (MAA) filing.

  • INDa Cleared for DELTA-2: Instil reported that in Q4 2021 the IND amendment was cleared for DELTA-2, a Phase 1 study of ITIL-168 in non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), cervical cancer, and cutaneous squamous cell carcinoma (CSCC).

  • Readiness to Initiate Phase 1 Study of ITIL-306 in 2022: Instil remains on track to file an IND for a Phase 1 study of its first genetically engineered CoStAR-TIL, ITIL-306, in multiple solid tumor indications in H1 2022.

  • Presenting Pre-clinical Data on the CoStAR Platform: Instil expects to present further pre-clinical data on the CoStAR platform, including manufacturability and in vivo models of efficacy and safety, at an upcoming scientific conference in 2022. In November 2021, Instil presented posters highlighting pre-clinical data from the CoStAR platform demonstrating how CoStAR expression led to marked enhancement of effector function and proliferation of T cells and TILs in the studies. Further details can be found in the poster publications available on the publication section of the Company's website.

  • Developing Novel CoStAR Constructs: Instil is developing novel, proprietary families of CoStAR constructs against new targets for solid tumors beyond the initial indications targeted for ITIL-306. Instil expects to select the next CoStAR candidate for IND-enabling studies in 2022.

  • Expansion of UK Manufacturing Facility Complete: Regulatory approval of the IMPACT manufacturing facility in Manchester, UK has been granted and clinical product manufacturing is ongoing. The opening of the IMPACT facility expands Instil’s clinical manufacturing capacity in Manchester, UK.

  • Validation of Tarzana Clinical Manufacturing Facility Ongoing: Validation of Instil’s clinical manufacturing facility in Tarzana, California is ongoing, with availability for clinical manufacturing expected in the first half of 2022. Upon readiness of the Tarzana clinical manufacturing facility, Instil expects to achieve manufacturing capacity of up to approximately 500 patient doses per year.
