TILT is building a pipeline of innovative cancer immunotherapies targeted at treating solid tumors – ovarian cancer evaluated as the lead indication.
The power of TILT’s approach which enables its proprietary oncolytic viruses to be encoded with a variety of cytokines, means that it should have applicability across a wide range of cancer indications, including ovarian and lung cancer, melanoma, and other solid tumors.

Science
Our patented TILT® technology, based on oncolytic viral therapies, modifies the tumour microenvironment and eliminates its ability to suppress immune responses to cancer, thereby enhancing T-cell therapies such as checkpoint inhibitors and CAR T-cell therapies.
Partners
Our pioneering approach has been recognized by industry leaders including Germany’s Merck KGaA and MSD (a tradename of Merck & Co., Inc.).
