Incendia's clinical trial is evaluating a DDR1 inhibitor called PRTH-101 that is given once every 21 days in combination with pembrolizumab.
DDR1, the Tumor Microenvironment, and PRTH-101
DDR1 (discoidin domain receptor 1) is a protein that binds to collagen and plays a key role in the way your cells move and grow. In tumors, DDR1 is an element of the tumor microenvironment.
The tumor microenvironment is a complex ecosystem of cells and other non-cellular components that surround and penetrate a solid tumor. The tumor microenvironment presents a structural and biochemical barrier that can block immune cell activity, thereby diminishing the effectiveness of treatments, including immunotherapies.
PRTH-101 binds to and inhibits DDR1, aiming to disrupt the tumor microenvironment's protection of tumors from treatment and immune cell activity.
There is no placebo in this study.
NSCLC Clinical Trial Information
PRTH-101-0001 is an open-label Phase 1 clinical trial for adults that have been diagnosed with metastatic or advanced solid tumors.
This is a two-part trial:
- Part 1 (Completed) – here the goal is to find the optimal dose of PRTH-101 when given alone and in combination with pembrolizumab.
- Part 2 (Open) – after the optimal dose of PRTH-101 is selected, the goal is to evaluate anti-tumor activity of PRTH-101 alone and in combination with pembrolizumab.
PRTH-101-0001 is currently enrolling participants with PD-L1 Negative or Low NSCLC who will receive PRTH-101 in combination with pembrolizumab.
