Voro Therapeutics develops tumor-activated biologics using its PrimeBody™ technology platform for systemic delivery with tumor-specific activation. This antibody-based platform employs finely tuned masking technology and conditionally activated linkers that cleave only within the tumor microenvironment. The resulting PrimeBodies aim to treat various cancers by avoiding on-target systemic toxicity and achieving a higher therapeutic index.

Problem
Systemic toxicity and off-target effects limit the therapeutic index of conventional cancer immunotherapies, hindering their ability to effectively target tumors while sparing healthy tissue. Broad tissue distribution of biologics can lead to significant side effects, reducing the potential for effective treatment.
Solution
Voro Therapeutics is developing the PrimeBody platform, an antibody-based therapeutic approach designed to selectively activate myeloid immune cells within the tumor microenvironment (TME). PrimeBody utilizes multi-specific antibodies that remain masked until they reach the TME, minimizing systemic toxicity and maximizing tumor specificity. By combining tumor-activation and targeted delivery, PrimeBody orchestrates both innate and adaptive immune responses, potentially leading to long-term cancer immunity. The modular design incorporates a tumor-targeting element, a protease-cleavable linker, a myeloid immune stimulator, and a myeloid immune checkpoint inhibitor, all within a single agent.
Target Audience
The primary target audience includes cancer patients and clinicians seeking more effective and less toxic immunotherapeutic options, as well as pharmaceutical companies developing next-generation cancer treatments.
