NEW YORK, Oct. 08, 2024 (GLOBE NEWSWIRE) -- MiNK Therapeutics (MiNK, NASDAQ: INKT) a clinical-stage company pioneering the development of allogeneic off-the-shelf, invariant natural killer T (iNKT) cell therapies and Autonomous Therapeutics, Inc. (Autonomous), a leader developing first-in-class, disease-activated RNA medicines, announced a research collaboration aimed at effectively targeting and treating metastatic tumors. This collaboration will leverage Autonomous’ precision encrypted RNA™ (encRNA) technology and MiNK’s innovative iNKT cell therapies, MiNK-215 and agenT-797. The companies will evaluate these technologies in state-of-the-art metastatic solid tumor models. The goal is to develop novel therapies that effectively target metastatic cancer cells in patients while avoiding healthy cells—a challenge that existing cancer medicines have not been able to overcome. Based on the results, the companies plan to launch a Phase 1 clinical trial in patients with treatment-refractory metastatic solid tumors, including microsatellite stable (MSS) colorectal cancers. “This collaboration underscores the unique potential of both native and engineered iNKT cells, allowing us to explore cutting-edge approaches that could significantly enhance clinical responses and deliver better outcomes for patients,” said Dr. Jennifer Buell, President and Chief Executive Officer at MiNK. “MiNK-215 and agenT-797 are novel cell therapies designed to overcome the limitations of traditional immune checkpoint inhibitors. Recent preclinical models of MSS colorectal cancer with metastatic liver disease demonstrated that these iNKT cells have the potential to eliminate tumor cells effectively. By combining them with Autonomous Therapeutics' engineered RNA technology, we are confident that we can unlock even greater therapeutic possibilities and continue advancing our mission to transform the landscape of cell therapy.” Dr. Ariel Weinberger, Chief Executive Officer of Autonomous, added: “This exciting collaboration leverages the platform capabilities of our next-generation encrypted RNA technology and MiNK’s unique allogeneic cell therapy platform. AT313 is a preclinical encRNA candidate developed at Autonomous to enable the precision targeting of solid tumors, via cancer-activated therapeutic protein translation. Our aim is to develop novel medicines that pinpoint tumor cells in patients—by sensing and targeting the aberrant molecular signatures that define cancer replication. This would enable us to eliminate cancer cells in patients while sparing healthy and immune cells. It would also eliminate dose-limiting toxicities common to existing oncology medicines while significantly enhancing therapeutic efficacy—to dramatically improve Stage IV patient outcomes.” About MiNK-215 MiNK-215 is an investigational, off-the-shelf cellular immunotherapy, specifically designed to target immune resistance mechanisms and promote a potent anti-cancer immune response. Engineered to express CAR targeting the Fibroblast Activating Protein (FAP) protein prevalent in stromal cells within the tumor microenvironment, MiNK-215 also integrates soluble IL-15 for enhanced persistence (Michelet X et al, SITC 2022; Shan K et al, AACR 2023; Dijk MV et al, CICON 2023). In preclinical models resistant to immune checkpoint inhibitors, MiNK-215 has demonstrated remarkable efficacy, not only in eliminating tumor cells and FAP+ immune-suppressive cells but also facilitating the infiltration and persistence of proinflammatory cytotoxic T cells crucial for effective tumor elimination. About agenT-797 AgenT-797 is an investigational, off-the-shelf immune cell therapy product by MiNK Therapeutics, possessing anti-viral and immune-modulating properties. In a Phase 1 trial involving 54 patients with heavily pre-treated solid tumors, agenT-797 appears to overcome resistance to immune checkpoint inhibitors, with durable disease stabilization in multiple solid tumors and a confirmed response in chemotherapy and anti-PD-1 refractory gastric cancer (Carneiro et al, 2024 Oncogene). agenT-797 is being evaluated in an investigator sponsored Phase 2 trial in 2L gastric cancer, led by Dr. Yelena Janjigian, Chief of GI Oncology at Memorial Sloan-Kettering Cancer Center and supported by Stand Up to Cancer.
