A First-In Human (FIH) Trial to Find Out if REGN10597 is Safe and How Well it Works for Adult Participants With Advanced Solid Organ Malignancies
Trial Status: active
This study is researching an experimental drug called REGN10597 (called "study drug").
The study is focused on patients with certain solid tumors that are in an advanced stage.
The aim of the study is to see how safe, tolerable, and effective the study drug is.
The study is looking at several other research questions, including:
- What side effects may happen from taking the study drug
- How much study drug is in the blood at different times
- Whether the body makes antibodies against the study drug (which could make the drug
less effective or could lead to side effects)
