Instil Bio (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 second quarter 2022 financial results and provided a corporate update.
Second Quarter 2022 Highlights and Anticipated Milestones:
- Enrollment ongoing in DELTA-1, a Phase 2 trial of ITIL-168 in advanced melanoma with registrational intent: Instil is targeting completion of enrollment in 1H 2023 for the registrational cohort and expects top-line safety and efficacy data in early 2024, which could potentially support a biologics license application (BLA) submission and a European Medicines Agency marketing authorization application (MAA) filing.
- Cash runway expected to extend from 2024 into 2025 with anticipated sale-leaseback of Tarzana, CA manufacturing site: Instil expects its current cash reserves along with expected proceeds from a potential sale-leaseback of its Tarzana, CA, manufacturing site to fund Company operations into 2025.
- Enrolling Phase 1 study of ITIL-306, Instil’s first CoStAR-TIL: Instil has initiated a Phase 1 study of ITIL-306, its first CoStAR-TIL product candidate. CoStAR is a genetic modification designed to enhance the activity of TILs within the tumor microenvironment. The Phase 1 study of ITIL-306 features a TIL treatment regimen free of IL-2 and will enroll patients with non-small cell lung cancer (NSCLC), ovarian cancer (OC), and renal cell carcinoma (RCC).
- Initiated DELTA-2, a Phase 1 study of ITIL-168 in combination with pembrolizumab: Instil has initiated DELTA-2, a Phase 1 study of ITIL-168 in combination with pembrolizumab, which will enroll patients with NSCLC, cervical cancer, and squamous cell carcinoma of the head and neck.
- Tarzana, CA manufacturing facility operational: Instil was cleared by the US Food and Drug Administration (FDA) for manufacturing of both ITIL-168 and ITIL-306 at its Tarzana, CA manufacturing facility, which will support DELTA-1, DELTA-2, and ITIL-306 clinical trials.
- Presented Preclinical Data on CoStAR T cells at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting: Instil presented findings from preclinical studies evaluating anti-FOLR1 CoStAR T cells in vitro as well as a murine solid tumor model in vivo demonstrating enhanced T cell function and tumor control by CoStAR-modified T cells.
Title: Antitumor activity of T cells expressing a novel anti-folate receptor alpha (FOLR1) costimulatory antigen receptor (CoStAR) in a human xenograft murine solid tumor model and implications for in-human studies.
- Presented Product Characterization Data from Unmodified TILs in Cutaneous Melanoma at the American Society of Gene and Cell Therapy (ASGCT): Instil presented advanced correlative analyses from a cohort of melanoma patients enrolled in a compassionate use program that were treated with TIL products made by Instil at the 25th Annual ASGCT meeting.
Title: Characterization of the Transcriptomic and TCR Clonal Heterogeneity of TIL Therapy Infusion Products by Single-Cell Sequencing and Correlative Analyses With Clinical Efficacy in Patients with Advanced Cutaneous Melanoma.
