Novastra Therapeutics

About

Novastra Therapeutics is a Boston-headquartered, clinical-stage biotechnology company pioneering Next-Generation Immune Reprogramming Therapy (XIRT) for solid tumors. We are engineering a paradigm shift beyond traditional cancer vaccines to deliver a system-level immune reset. While current immunotherapies often fail due to the complexity of the Tumor Microenvironment, Novastra’s approach is designed to overcome the full spectrum of resistance phenotypes. This includes addressing the "immune desert" where T-cells are absent, breaching physical "immune exclusion" barriers, and revitalizing the "functional desert"—a critical state where immune cells are present but rendered metabolically exhausted and dysfunctional. At the core of our pipeline is the OmniAntigen™ Platform (OAP). Utilizing our proprietary metal-organic nanocloak technology, we convert a patient’s own tumor cells into a potent, multi-valent therapeutic in a same-day, hospital-ready process. Unlike standard approaches that rely on prediction, our supramolecular assembly instantly preserves the patient’s entire tumor antigen repertoire while co-delivering potent STING pathway agonists directly to dendritic cells. This unique surface engineering re-educates the immune system to break tolerance and spark a robust, adaptive response. Our lead program, OAP-101, is actively advancing in clinical trials for checkpoint-inhibitor-refractory solid tumors. To maintain high-velocity execution, Novastra operates with a strategic global footprint: we anchor our innovation and corporate strategy in Boston/Cambridge, while leveraging a dedicated business operations and clinical center in Shanghai. This dual-engine structure allows us to accelerate data generation and redefine clinical outcomes for the hardest-to-treat cancers.
