- Realigning resources to focus on clinical advancement of Selected TIL therapy
- Reducing employee headcount by approximately 60%
- Streamlining operations with cash runway expected to extend into 2Q 2026
SAN DIEGO, Oct. 11, 2024 (GLOBE NEWSWIRE) — Turnstone Biologics Corp. (“Turnstone” or the “Company”) (Nasdaq: TSBX), a clinical-stage biotechnology company developing a differentiated approach to treat and cure patients with solid tumors by pioneering selected tumor-infiltrating lymphocyte (Selected TIL) therapy, today announced a strategic prioritization of its pipeline, as well as a workforce reduction of approximately 60% and changes to its leadership team, to focus resources on the continued advancement of its Phase 1 program, TIDAL-01. As a result of the restructuring initiatives that align with the Company’s near-term goals, the anticipated cost savings are expected to extend its cash runway into the second quarter of 2026 and maximize shareholder value.
“Following a comprehensive evaluation of our business operations, we have decided to prioritize our pipeline and sharpen our clinical focus,” said Sammy Farah, M.B.A., Ph.D., Turnstone’s President and Chief Executive Officer. “As a result, we have made the decision to streamline our team, align resources towards manufacturing and clinical development, and optimize our cost structure. We expect these changes will extend our cash runway by three additional quarters, further enabling us to build upon our encouraging initial Phase 1 data, which demonstrated the potential of our Selected TILs in high unmet need solid tumors and potentially generate near-term value for our shareholders, while continuing to shape a strong company for the future.”
Dr. Farah added: “These mission-driven measures impact a number of our talented colleagues. I would like to convey my gratitude for their innumerable contributions to Turnstone, their commitment to patients with solid tumors, and I wish them the very best in their future endeavors.”
The comprehensive review of the Company’s corporate outlook and pipeline have outlined the following key strategic decisions:
Portfolio Prioritization
- The Company will direct resources towards advancing the development of its clinical program, TIDAL-01, over other preclinical pipeline assets. Turnstone’s Selected TIL process is designed to utilize a novel unbiased identification and functional screening method to isolate and selectively expand the greatest breadth of the most potent tumor-reactive TIL from the patient’s tumor in vitro, before infusing them into the patient for more targeted tumor killing.
- Turnstone recently reported initial positive data from the STARLING trial that support the biological hypothesis for TIL selection and warrant further development. The initial data showcased the achievement of a complete response in a heavily pre-treated late-line microsatellite stable colorectal cancer (MSS-CRC) patient with progression free survival extending beyond one year.
- TIDAL-01 is currently being evaluated in multiple Phase 1 trials including patients with colorectal cancer, head and neck cancer, and uveal melanoma, and the Company expects to provide a clinical update in the first half of 2025.
Workforce Reduction
- Turnstone is executing an approximately 60% reduction in its workforce. The Company expects that the combined efforts from the corporate reorganization and clinical program prioritization will extend cash runway into the second quarter of 2026.
Leadership Transitions
- Ines Verdon, M.D., Senior Vice President of Clinical Development, is assuming leadership of all clinical activities. Dr. Verdon joined Turnstone in 2022 and has more than 20 years of academic and pharmaceutical industry oncology and cell therapy experience. Michael Burgess, MBChB, Ph.D., is retiring as Interim Chief Medical Officer and will continue to serve as a member of the Turnstone Board of Directors.
- Michael Fitch, Ph.D., has been promoted to Senior Vice President of Manufacturing and will oversee all manufacturing and technical operations activities. Dr. Fitch joined Turnstone in 2023, bringing almost 20 years of biotechnology and pharmaceutical industry experience, including approximately a decade in cell therapy technical operations, CMC (Chemistry, Manufacturing, and Controls), and manufacturing. Vijay Chiruvolu, Ph.D., Interim Chief Technology Officer, has completed his agreed to term of service with Turnstone and is moving into a strategic advisory role for the Company.
- Wendy Worcester, CPA, current Vice President of Finance, will assume responsibility of the Finance function as the Principal Financial and Accounting Officer. Ms. Worcester joined Turnstone in 2022 and is a skilled business and finance professional with over 20 years of financial and accounting experience. Venkat Ramanan, Ph.D., will be stepping down from his role as Chief Financial Officer.
- Saryah Azmat has been promoted to Chief Operating Officer. Ms. Azmat served as the Company’s Chief Business Officer since 2021, and prior to this, as the Company’s Senior Vice President of Business Development and Corporate Strategy from 2019 to 2021.
