T-knife Therapeutics Files Clinical Trial Application for Phase 1 ATLAS Trial for TK-6302, a Supercharged PRAME-targeted T Cell Receptor Therapy

-- Preclinical data with TK-6302 has shown best-in-class anti-tumor efficacy, demonstrating its potential to elicit deep and durable responses in diverse solid tumor indications with high unmet need

-- Following CTA approval, Phase 1 ATLAS trial planned to begin in 2026

SAN FRANCISCO and BERLIN, Nov. 17, 2025 (GLOBE NEWSWIRE) -- T-knife Therapeutics, Inc., a biopharmaceutical company developing next-generation T cell therapies to fight cancer, today announced the filing of a Clinical Trial Application (CTA) to begin the Phase 1 ATLAS trial for TK-6302, a Supercharged PRAME-targeted TCR T cell therapy in solid tumors. PRAME is a validated target expressed in multiple solid tumor indications with high unmet need, including squamous non-small cell lung, ovarian, endometrial, skin, and triple negative breast cancers.

“The filing of this clinical trial application is a notable achievement, both for the development of TK-6302 and for our company,” stated Thomas M. Soloway, President and Chief Executive Officer of T-knife. “This milestone reflects the unwavering commitment of our employees to boldly innovate and redefine solutions in the service of solid tumor patients. We have pioneered novel technologies with TK-6302 that demonstrate best-in-class preclinical results in enhancing T cell fitness, persistence and anti-tumor activity, while overcoming immune barriers. Empowered by these novel advances, we are excited by the prospect of initiating the ATLAS trial to evaluate the potential of TK-6302.”

TK-6302 is a PRAME-targeted TCR-T that has been “supercharged” by the inclusion of key differentiating innovations: a high affinity TCR to enhance cytotoxicity; a costimulatory CD8 coreceptor to engage CD4 T cells and enhance T cell fitness and persistence; and a FAS-based checkpoint converter designed to boost engraftment and promote T cell survival in the hostile tumor micro-environment. Preclinical data with TK-6302 demonstrated sustained serial killing and cytokine secretion in a model mirroring the inhibitory ligand expression in PRAME-expressing tumors. In a complex 3-dimensional (3D) spheroid tumor model, TK-6302 eliminated multiple rounds of tumors and demonstrated superior anti-tumor activity compared to controls. TK-6302 is manufactured with a non-viral gene editing process for improved TCR expression, and it has been successfully manufactured at-scale using the clinical process.
