The Traverso Lab developed a gel-based platform for injecting immune-stimulating drugs directly into tumors. Ideally, direct injection of these drugs into a tumor will provoke a system-wide immune response, while avoiding the serious toxic side effects of systemic administration. In practice, tumors are difficult to target with precision and the drugs tend to leak away from the tumor too quickly. The team worked with colleagues at Mass General Brigham to design a thermoresponsive gel that is visible with a CT scanner, solidifies after injection, and releases drugs at a controlled rate. An Advanced Healthcare Materials study showed that in combination with checkpoint blockade therapy, the platform caused both treated tumors and untreated tumors at other locations to regress in mouse models.
