Summary
This phase 3 trial tests an experimental drug called REGN7508 to prevent blood clots in people with solid tumors who are receiving cancer treatment. About 1,120 participants will receive either the drug or a placebo. The study measures how well the drug prevents clots and checks for side effects like bleeding.
What this could mean

- What this could lead to
- If successful, this could provide a new way to prevent dangerous blood clots in people with cancer, reducing the risk of stroke or death.
- What could go wrong
