New hope for cancer patients: experimental drug aims to stop dangerous blood clots
NCT ID NCT07493304
First seen Jun 27, 2026 · Last updated Aug 20, 2026 · Updated 4 times
Summary
This study tests an experimental drug, REGN7508, to see if it works better than the standard blood thinner apixaban for treating and preventing blood clots in people with cancer. The trial will include about 1,600 participants with or without cancer who have deep vein thrombosis or pulmonary embolism. Researchers will monitor safety, side effects, and how well the drug prevents new clots.
