Frequently asked questions about HMB-003

What is HMB-003?

HMB-003 is an investigational small molecule developed by Hemab Therapeutics Holdings, Inc. It is designed to target plasmin and is currently in Phase 1 clinical development. The specific patient populations it may eventually treat have not been publicly disclosed.

What does HMB-003 target?

HMB-003 targets plasmin. Plasmin is an enzyme involved in breaking down blood clots and in other proteolytic processes. By acting on plasmin, HMB-003 is being studied as a small molecule therapeutic, though its intended disease indications have not been disclosed.

Who is developing HMB-003?

HMB-003 is being developed by Hemab Therapeutics Holdings, Inc., which trades under the ticker COAG. The company is running the first-in-human study of the compound in the United States.

What phase is HMB-003 in?

HMB-003 is in Phase 1 development. It is investigational and has not been approved by the FDA. The ongoing first-in-human trial is a Phase 1 study evaluating safety, pharmacokinetics, and pharmacodynamics in healthy adult volunteers.

What clinical trials is HMB-003 in?

HMB-003 is being studied in one active clinical trial, NCT07798505, titled a first-in-human study to assess the safety, pharmacokinetics, and pharmacodynamics of HMB-003 in healthy volunteers. The trial is currently recruiting, is placebo-controlled and double-blind, and plans to enroll 40 participants in the United States.

Who can enroll in the HMB-003 trial?

The Phase 1 trial of HMB-003, NCT07798505, enrolls healthy adult volunteers age 18 years and older, with no restriction by sex. It is a randomized, double-blind, placebo-controlled first-in-human study of 40 participants conducted in the United States.
