PRTH-101 for Advanced Solid Tumors

This study is testing a new treatment called PRTH-101, either by itself or with pembrolizumab, for adults with advanced or metastatic (spread to other parts of the body) solid tumors, including non-small cell lung cancer. PRTH-101 is a special antibody designed to break down a barrier around tumors, allowing the body's immune cells to attack them more effectively. Researchers want to see how safe PRTH-101 is, what dose works best, and if it can shrink tumors. The study aims to enroll up to 270 participants.

Study design
This is an open-label study, meaning both you and your doctors will know which treatment you are receiving. It is testing PRTH-101 alone or in combination with pembrolizumab.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for up to 4 years to evaluate side effects, the best dose, and how the drug moves through the body.
