REGN7508 in Adult Participants for Prevention of Cancer-Associated Thrombosis
United States, Georgia860 participantsStarted 2026-03-09
Plain-language summary
This study is researching an experimental drug called REGN7508 (called "study drug"). The study is focused on the prevention of Cancer-Associated Thrombosis (CAT) in participants.
The aim of the study is to see how effective the study drug is in preventing blood clots in participants with solid tumors who are currently receiving anticancer treatment or planning to start anticancer treatment within a month of being assigned to a study treatment, or recovering from surgery, and how the study drug compares to placebo for CAT.
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 study drug less effective or could lead to side effects)

Inclusion criteria
✓. Has a histologically confirmed diagnosis of malignant solid tumors which are locally advanced or metastatic as described in the protocol
✓. Has a Khorana thromboembolic risk score ≥2 at the time of screening or harbors a somatic documented tumor genetic variant known to be associated with an increased risk of VTE as described in the protocol
✓. Has an Eastern Cooperative Oncology Group (ECOG) Performance Status 0 to 2 at the time of screening and day 1 prior to the first dose of study intervention
Exclusion criteria
✕. Has known bleeding conditions (eg, Hemophilia A or B, von Willebrand's disease), hemorrhagic tumor sites, or other conditions with a high risk for bleeding (eg, hepatic disease associated with coagulopathy)
✕. Has a cancer diagnosis consisting solely of basal cell or squamous cell skin carcinoma
✕. Has a primary brain tumor or brain metastases as described in the protocol
✕. Has a history of objective evidence of VTE or ATE, including incidental VTE identified by diagnostic imaging requiring anticoagulation
What they're measuring
1
Time-to-first event of centrally adjudicated VTE [Deep Vein Thrombosis (DVT), non-fatal Pulmonary Embolism (PE) or Arterial thromboembolism (ATE), or thromboembolism- or ATE-related death]
Timeframe: Through 6 months
2
Time-to-first event of centrally adjudicated International Society of Thrombosis and Hemostasis (ISTH) major bleeding or Clinically Relevant Non-Major (CRNM) bleeding
. Has any condition that, as judged by the investigator, may confound the results of the study or would place the participant at increased risk of harm if he/she participated in the study
