HOWL
Werewolf Therapeutics, Inc. is a biopharmaceutical company pioneering the development of therapeutics engineered to stimulate the body's immune system for the treatment of cancer. The company utilizes its proprietary PREDATOR® protein engineering platform to create a novel class of conditionally activated proinflammatory immune modulators, known as INDUKINE™ and INDUCER™ molecules. These therapies are designed to be delivered systemically in an inactive state and become selectively activated within the tumor microenvironment. This approach aims to generate a potent, localized anti-tumor immune response while minimizing the systemic side effects associated with conventional immunotherapies. The company's pipeline includes clinical-stage candidates such as WTX-124 and WTX-330.
