The advancement of Turnstone Biologics' lead program, TIDAL-01, into Phase 1 clinical trials is a significant milestone in the field of oncology, particularly for solid tumor therapies. TIDAL-01's unique approach to isolating and expanding tumor-reactive TILs could potentially offer a new treatment paradigm for solid tumors, which historically have been challenging to treat with first-generation TILs. The focus on a broader range of solid tumors, including colorectal cancer and head and neck squamous cell carcinoma, indicates an attempt to address areas of high unmet medical need. The preclinical data presented at SITC 2023 adds credibility to the therapeutic potential of TIDAL-01, suggesting a possible positive impact on Turnstone's valuation if the clinical data expected in mid-2024 is favorable.
From an R&D perspective, the reported decrease in expenses is noteworthy. This decrease is attributed to the termination of a collaboration with Takeda Oncology, which seems to have allowed for a reallocation of resources towards the TIDAL-01 program. The financial runway extending into the second quarter of 2025 provides a reasonable buffer for Turnstone to reach key milestones without immediate dilutive financing concerns.
Turnstone Biologics' financial results for the fourth quarter and full year of 2023 reflect a strategic shift in the company's operations. The reduction in R&D expenses year-over-year, despite the ramp-up of TIDAL-01 activities, could be seen as a positive indicator of management's ability to control costs effectively. However, investors should consider the increase in net loss for the full year when evaluating the company's performance. This increase in net loss may raise questions about the scalability of Turnstone's business model and the potential need for additional funding, especially as the company approaches the critical data release in mid-2024.
It is also important to monitor the company's cash burn rate in relation to the anticipated clinical trial milestones. While the current cash position is expected to last into Q2 2025, the outcome of the TIDAL-01 trials will likely influence future financing needs and partnership opportunities. Any delays or negative results could have a substantial impact on the company's financial health and stock price.
The landscape of cancer immunotherapy is highly competitive, with many companies vying for a share of a growing market. Turnstone's decision to diversify its trial indications to include additional solid tumor types suggests an attempt to capture a larger market segment. The company's strategic positioning, with a focus on solid tumors that have not responded well to first-generation TILs, could differentiate it from competitors if successful. This differentiation is critical as it may lead to partnerships, licensing deals, or even acquisition interest from larger pharmaceutical companies looking to expand their oncology portfolios.
Turnstone's engagement and expansion of its Scientific Advisory Board with experts like Dr. Jeffrey S. Weber can also be seen as a move to bolster the company's scientific credibility and networking within the oncology community. This could potentially facilitate future collaborations and enhance the company's reputation in the eyes of investors and industry peers.

SAN DIEGO, March 21, 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 reported financial results for the fourth quarter and full year ended December 31, 2023, and provided recent business highlights.
“2023 marked a transformative year for Turnstone Biologics in which we transitioned into a publicly traded company and continued to advance our pipeline through clinical development. We are encouraged by the increasing momentum in the TIL landscape that paves the way for next-generation approaches like our Selected TIL therapy, which is designed to create a TIL product with a significantly greater population of potent tumor-reactive T cells, which we believe is the key to extending their therapeutic potential to high unmet medical needs in solid tumors beyond melanoma,” said Sammy Farah, M.B.A., Ph.D., Turnstone’s President and Chief Executive Officer. “In 2024, we look forward to generating clinical data that potentially highlights the differentiation of our platform and supports further development of our lead asset, TIDAL-01, which is currently being evaluated in Phase 1 studies in patients with colorectal cancer, head and neck squamous cell carcinoma, breast cancer, uveal melanoma, and cutaneous melanoma. We remain on-track to share initial clinical data for TIDAL-01 in mid-2024 and we believe we are well-positioned for another year of meaningful progress for our organization.”
Fourth Quarter and Recent Business Highlights
Advancing TIDAL-01 in Multiple Phase 1 Clinical Trials and Expanding of Targeted Solid Tumor Indications. TIDAL-01 employs an unbiased identification and functional screening process to isolate and selectively expand the greatest breadth of tumor-reactive TILs from the patient’s tumor. Turnstone believes TIDAL-01 can expand the utility of TIL therapy to solid tumor types where first-generation TILs have not to date shown objective responses in clinical trials and is pursuing several indications with critical unmet need, potentially enabling meaningful therapeutic differentiation. Recently, Turnstone expanded their trials to evaluate additional solid tumor types in addition to the existing indications of breast cancer and uveal melanoma. The multi-site STARLING trial protocol has been amended to cover head and neck squamous cell carcinoma (HNSCC), and the H. Lee Moffitt Cancer Center and Research Institute sponsored trial has been expanded to include colorectal cancer (CRC) and HNSCC. Turnstone expects to provide an initial clinical update across these trials in mid-2024.
Preclinical Data Presentations at the 2023 Society for Immunotherapy of Cancer (SITC) Annual Meeting Support Ongoing Clinical and Preclinical Efforts. In November 2023, Turnstone presented preclinical data on its Selected TIL therapies, including the demonstration of the feasibility of selecting and expanding tumor-reactive TIL as further evidence for the potential of TIDAL-01 as a treatment option for patients with colorectal and gastric cancers. Turnstone also presented on its next Selected TIL program from its development pipeline, TIDAL-02, which seeks to utilize a novel direct selection method, genetically engineered to rapidly select for the greatest breadth of tumor-reactive T cells.
Strengthened Company’s Scientific Advisory Board. In October 2023, Turnstone appointed Jeffrey S. Weber, M.D., Ph.D., to its Scientific Advisory Board. Dr. Weber, a world-renowned thought leader with extensive experience in innovative immunotherapies for solid tumors, currently serves as Deputy Director of the Perlmutter Cancer Center and Co-Director of the Melanoma Research Program at the New York University-Langone Cancer Center.
