Nasdaq Approves to Transfer Listing of Turnstone Biologics Common Stock from Nasdaq Global to Nasdaq Capital Market As previously reported, on September 27, 2024, Turnstone Biologics Corp. received a letter from The Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company no longer met the minimum bid price requirement set in Nasdaq Listing Rule 5450(a)(1) (the “Minimum Bid Price Requirement”) because the closing bid price for the Company’s common stock was less than $1.00 for the previous 30 consecutive business days. Under Nasdaq Listing Rule 5810(c)(3)(A), the Company had a 180-calendar day grace period, or until March 26, 2025, to regain compliance with the Minimum Bid Price Requirement. On March 24, 2025, the Company applied to transfer the listing of its common stock from The Nasdaq Global Market to The Nasdaq Capital Market. On March 27, 2025, the Company received approval from the Listing Qualifications Department of Nasdaq to transfer the listing of the Company’s common stock from the Nasdaq Global Market to the Nasdaq Capital Market (the “Approval”). The Company’s securities will be transferred to the Capital Market at the opening of business on March 31, 2025. The Company’s common stock will continue to trade under the symbol “TSBX.” The Nasdaq Capital Market operates in substantially the same manner as the Nasdaq Global Market, but with less stringent listing requirements, although listed companies must meet certain financial requirements and comply with Nasdaq’s corporate governance requirements. In connection with the Approval, the Company has been granted an additional 180-day grace period, or until September 22, 2025, to regain compliance with the Minimum Bid Price Requirement. To regain compliance with the Minimum Bid Price Requirement and qualify for continued listing on the Nasdaq Capital Market, the minimum bid price per share of the Company’s common stock must be at least $1.00 for at least ten consecutive business days during the additional 180-day grace period. If the Company does not regain compliance during this additional grace period, its common stock would be subject to delisting by Nasdaq. As part of its transfer application, the Company notified Nasdaq that in order to regain compliance with the Minimum Bid Price Requirement during the additional grace period, it will implement a reverse stock split, and has filed a proxy statement soliciting a stockholder vote on such reverse stock split. If the Company’s stock becomes subject to delisting as a result of the Company’s failure to regain compliance with the Minimum Bid Price Requirement by September 22, 2025, the Company may appeal the decision to a Nasdaq Hearings Panel. In the event of an appeal, the Company’s common stock would remain listed on the Nasdaq Capital Market pending a written decision by the Nasdaq Hearings Panel following a hearing. In the event that the Nasdaq Hearings Panel determines not to continue the Company’s listing and the Company’s common stock is delisted from The Nasdaq Capital Market, the Company’s common stock may trade on the OTC Bulletin Board or other small trading markets, such as the pink sheets.

Turnstone Biologics Corp. Presents Preclinical Data Highlighting Potential for Selected Tumor-Infiltrating Lymphocyte Therapy in Solid Tumors at the 2024 Society for Immunotherapy of Cancer Annual Meeting Turnstone Biologics Corp. announced it will be presenting two posters highlighting preclinical data on methods for TIL selection at the Society for Immunotherapy of Cancer (SITC) 39th Annual Meeting being held November 6-10, 2024 in Houston, Texas. In collaboration with the University of Montreal Hospital Research Centre (CRCHUM). Although tumor-reactive TIL infused to patients are associated with clinical responses, there are currently no biomarkers that can predict whether tumor-reactive T cells can be expanded from a tumor. Using single T cell sequencing, this poster illustrates a manufacturing method tested to enrich TIL in tumor-reactive T cells, the results for which suggest that the degree of baseline TCR (T cell repertoire) overlap between blood and tumor repertoire could help identify patients from which tumor-reactive TIL can be expanded.

Turnstone Biologics Receives Notice from Nasdaq Regarding Non-Compliance with the Minimum Bid Price Requirement for Continued Listing on The Nasdaq Global Select Market under Listing Rule 5450(a)(1) On September 27, 2024, Turnstone Biologics Corp. received notice (the ‘Notice’) from the Listing Qualifications staff of the Nasdaq Stock Market LLC (‘Nasdaq’) that, because the closing bid price of Turnstone’s common stock was below $1.00 per share for 30 consecutive business days, Turnstone no longer complies with the minimum bid price requirement for continued listing on the Nasdaq Global Select Market under Nasdaq Listing Rule 5450(a)(1). The Notice has no immediate effect on the listing of Turnstone’s common stock on Nasdaq. Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided an initial compliance period of 180 calendar days, or until March 26, 2025, to regain compliance with the minimum bid price requirement. To regain compliance, the closing bid price of the Company’s common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days prior to March 26, 2025. If Turnstone does not regain compliance by March 26, 2025, the Company may be eligible for an additional 180 calendar day grace period if it applies to transfer the listing of its common stock from the Nasdaq Global Select Market to the Nasdaq Capital Market. To qualify, Turnstone would be required to meet the continued listing requirement for the market value of its publicly held shares and all other initial listing standards, with the exception of the minimum bid price requirement, and provide written notice to Nasdaq of its intention to cure the minimum bid price deficiency during the second compliance period by effecting a reverse stock split, if necessary. If the Nasdaq staff determines that Turnstone will not be able to cure the deficiency, or if Turnstone is otherwise not eligible for such additional compliance period, Nasdaq will provide notice that Turnstone’s common stock will be subject to delisting. Turnstone is presently evaluating potential actions to regain compliance with the continued listing requirements of Nasdaq. There can be no assurance that the Company will be able to regain compliance with the minimum bid price requirement or will otherwise be in compliance with other Nasdaq listing criteria.

Turnstone Biologics Corp. Reports Positive Initial Data from Phase 1 Trial of TIDAL-01 in Metastatic Colorectal Cancer Turnstone Biologics Corp. reported positive initial data from its Phase 1 STARLING trial of TIDAL-01 in metastatic microsatellite stable colorectal cancer (“MSS mCRC”). Turnstone’s Phase 1 STARLING trial is an ongoing muti-site, first-in-human, non-randomized, open label, single-dose study, and is evaluating the safety, tolerability, and clinical activity of TIDAL-01. The trial is currently enrolling patients with colorectal cancer, head and neck squamous cell carcinoma, and uveal melanoma. As of the cutoff date of July 15, 2024, key takeaways from the initial data include the following: Clinical Responses: Among the four evaluable MSS mCRC patients included in the study, Turnstone observed a 25% overall response rate ("ORR") and 50% disease control rate ("DCR"). One patient demonstrated a deep and durable ongoing complete response (CR). Durability of Response: 50% of patients showed sustained clinical benefit, with notable progression free survival of over one year in the patient with ongoing complete response and 6 months for a patient with stable disease.
Translational Profile: The TIDAL-01 process demonstrated the ability to generate high titer, polyclonal and multi-epitope tumor neoantigen-reactive T cells that expanded in the patient, persisted in the blood and correlated with an increase in CD8 T cell tumor infiltration. Tolerability Profile: TIDAL-01 was generally well-tolerated and safety events observed were consistent with known AEs associated with the lymphodepletion regimen, and IL-2 and pembrolizumab administration. Manufacturing Rates: The manufacturing success rate for TIDAL-01 in CRC for patients with sufficient starting material was 80%, which is consistent with other early clinical-stage cell therapy processes. The target dose of at least 1x10 total T cells was exceeded in all manufactured CRC products. Ankündigung • Jul 03

Turnstone Biologics Presents Preclinical Data Highlighting Potential for Selected Tumor-Infiltrating Lymphocyte Therapy in Solid Tumors At the 2023 Society for Immunotherapy of Cancer Annual Meeting Turnstone Biologics Corp. announced it will be presenting four posters highlighting preclinical data from its pipeline of programs, including the lead clinical candidate, TIDAL-01, at the Society for Immunotherapy of Cancer (SITC) 38th Annual Meeting being held November 1-5, 2023 in San Diego, California. Key findings from the four poster presentations follow, copies of which will be added to Turnstone’s website and can be accessed here. Title: Expansion and Identification of Neoantigen-Reactive Tumor-Infiltrating Lymphocytes (TIL) from Metastatic Colorectal (CRC) and GI Cancers Date and Time: November 4, 2023, 9:00am - 8:30pm PT Abstract Number: 346 In collaboration with H. Lee Moffitt Cancer Center (Moffitt) Turnstone’s lead Selected TIL clinical candidate, TIDAL-01, utilizes a novel unbiased identification and functional screening process to isolate and selectively expand the greatest breadth of the most potent tumor-reactive (neoantigen-reactive) TIL from the patient’s tumor in vitro, before infusing them into the patient for more targeted tumor killing. This poster demonstrates that TIL from metastatic colorectal cancer and gastric cancer patient samples were successfully expanded from multiple disease sites in vitro. TIL from these samples were screened for neoantigens and enriched for neoantigen-reactive TIL, and furthermore, maintained reactivity following expansion. These results, along with previous findings for TIDAL-01 and from within the field, highlight the practicality of selecting and expanding tumor-reactive TIL as a potential treatment option for colorectal and gastric cancer patients. Title: TBio BFX 4101: A Neoantigen Prioritization Pipeline for Selected Tumor-Infiltrating Lymphocyte Therapy Date and Time: Saturday, November 4, 2023, 9:00am - 8:30pm PT Abstract Number: 900 Identifying tumor-specific neoantigens arising from somatic mutations is one of the differentiating features of Turnstone’s Selected TIL process for TIDAL-01. In this poster, Turnstone presents TBio BFX 4101, a bioinformatics pipeline, which provides a comprehensive and efficient approach to identifying and ranking these neoantigens, with encouraging results from a variety of solid tumor samples, including melanoma, colon, and breast cancers. Title: Tumor Neoantigen Prioritization from Liquid Biopsy Whole Exome Sequencing for Selected Tumor-Infiltrating Lymphocyte Therapy Date and Time: Saturday, November 4, 2023, 9:00am - 8:30pm PT Abstract Number: 178 In collaboration with Illumina Inc. Whole exome DNA and RNA sequencing were applied to patient liquid biopsy samples to assess the sensitivity of tumor variant detection and prioritization of neoantigen peptides in comparison with tissue data. This presentation highlights that minimally invasive liquid biopsy is viable for the detection of somatic variants in preclinical studies, and this approach to identifying neoantigens may increase the breadth and number of tumor-reactive T cells. Title: Enhancing Directly Selected Tumor-Reactive TIL Function Through Genetic Modification Date and Time: Saturday, November 4, 2023, 9:00am - 8:30pm PT Abstract Number: 350 Distinct from, yet complementary to TIDAL-01, Turnstone is developing a preclinical program associated with a next-generation direct selection process. Direct selection utilizes a proprietary combination of markers designed to rapidly select for the greatest breadth of tumor-reactive T cells without the requirement for sequencing or peptide generation. Turnstone scientists are presenting preclinical data highlighting that directly selected tumor-reactive TIL can be genetically engineered using CRISPR-Cas and demonstrate that knocking out genes of interest can potentially enhance directly selected TIL quality and function.
