New shot aims to stop catheter clots without blood thinners
NCT ID NCT07498517
First seen Jun 26, 2026 · Last updated Sep 01, 2026 · Updated 3 times
Summary
This Phase 2 trial tests whether a single dose of gruticibart, a monoclonal antibody, can prevent blood clots that often form when a central venous catheter is placed. About 90 adults getting a catheter will receive either the drug or a placebo. The goal is to see if gruticibart reduces clots and the need for risky blood thinners.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- gruticibart (a monoclonal antibody)
- What this could lead to
- If it works, this could offer a way to prevent catheter-related blood clots without the bleeding risks of standard blood thinners.
- What could go wrong
- This is an early Phase 2 trial with only 90 participants, so results may not apply to everyone. The drug could still cause bleeding or other side effects.

Inclusion Criteria: * Ability to understand and the willingness to sign a written informed consent document. * Men and women, aged ≥ 18 years. * In consultation with PI and treating physician, participant's therapy allows for a 1 to 2-day period between administration of study drug and subsequent start of planned therapy. * Individuals that will undergo insertion of a CVC as part of planned therapy per institutional standards. * Must have ECOG performance status ≤ 2 (refer to Appendix A). * At time of enrollment, must have: * Platelet count \> 50 x 109/L * Female participants of childbearing potential must have a negative urine or serum pregnancy test during screening and at check-in Day -1. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. * Participants of childbearing potential are defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) and is not postmenopausal. * Female participants of childbearing potential must agree to use two forms of highly effective contraception (Appendix B) starting with the first dose of study therapy through 90 days after the last dose of study therapy. Participants of childbearing potential are those who have not been surgically sterilized or have not been free from menses for \>1 year without an alternative medical cause. * Male participants must agree to use an adequate method of contraception starting with the first dose of study therapy through 90 days after the last dose of study therapy. Exclusion Criteria: * Concurrent enrollment in another therapeutic clinical trial * Active leukemia (lymphoma and myeloma may be included) * Primary brain tumors or known brain metastases * Active infection and/or current use of an oral antibiotic * At time of enrollment: * Deranged baseline clotting, where INR \> 1.5 * Known bleeding diathesis * Use of anticoagulation, either therapeutic or prophylactic, for any indication at enrollment * -At the discretion of the investigator, any other contraindication to anticoagulation therapy * Previously documented hypersensitivity to either the drug or excipients. * Psychiatric illness/social situations, or any other condition, that in the opinion of the investigator, would limit compliance with study requirements. * Participant is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 90 days after study drug administration.
