Blood Clotting Therapies At

Hemab is pioneering the first targeted preventative treatments and functional cures for underserved bleeding and thrombotic disorders—reimagining the standard of care for patients everywhere.

Our Approach

No Patient With A
Clotting Disorder

While patients with common bleeding and thrombotic disorders have had access to preventative treatments for more than a half-century, no such measures exist for less-common disorders.

For these tens of thousands of men, women, and children, life is paralyzingly unpredictable. A bleeding or thrombotic event can strike any moment, from a simple menstrual period to a routine dental procedure, and cause symptoms so severe that by the time they reach a hospital, it may be too late.
It’s time to ensure that every clotting disorder patient has the security and peace of mind they deserve.

The First-Ever Preventative Treatments For

Hemab is leapfrogging technological advancements to deliver the first ever prophylactic treatments and functional cures for the full spectrum of genetically driven bleeding and thrombotic disorders to prevent life-threatening complications and offer patients a new lifeline. 
Essentially, the body’s bleeding and thrombosis pathway is fine-tuned, and there are numerous points within it that can fail, causing disease. Our novel therapies are designed to accumulate, modulate/balance, and at times recruit endogenous clotting factors already present in the blood to the site of injury to enable patients to form hemostatic plugs (or, clots) at the right times and in the right places.

Our therapeutic candidates* bind the body’s native clotting factor(s) with high specificity and affinity. This binding can stabilize the native clotting factor(s), preventing breakdown and allowing accumulation to therapeutic levels. Furthermore, the binding can be neutral (preserving the activity of the native clotting factor) or inhibitory (inactivating the clotting factor), giving us the versatility to address challenges across the clotting pathway. Our state-of-the-art technology also allows us, when necessary, to recruit native clotting factors directly to the site of injury.

Our Pipeline

Preventing The Full Spectrum Of


Leveraging validated advanced technologies and key insights into the biology of clotting, Hemab’s approach is prime for widespread expansion into a range of underserved bleeding and thrombotic disorders, including Glanzmann Thrombasthenia, Factor VII Deficiency, Hemophilia B with inhibitors, Bernard Soulier Syndrome, Von Willebrand Disease, Hereditary Hemorrhagic Telangiectasia (or Osler-Weber-Rendu disease), Congenital Antithrombin III Deficiency, and others.

We are committed to finding and serving patients that have been left behind despite recent innovative therapies. Our strategic guidance, Hemab 1-2-5TM is targeting development of five clinical assets by 2025 to transform treatment for these rare disorders and enable patients everywhere to live healthy, active lives.

Hemab 1-2-5TM: 5 Clinical Assets by 2025
Phase I
Phase II
HMB-001 (Bleeding)
Lead candidate HMB-001 is a bispecific antibody that binds, stabilizes, and recruits endogenous factor VIIa (FVIIa) to the site of vascular injury to overcome the body’s inability to form healthy clots—building on the longstanding efficacy of recombinant FVIIa with the benefit of prophylaxis. Indicated for Glanzmann Thrombasthenia, Factor VII Deficiency, Hemophilia B with inhibitors, Bernard Soulier Syndrome
HMB-VWF (Bleeding)
HMB-VWF is designed as a prophylactic treatment for Von Willebrand Disease Type 1 and 2
HMB-TAF (Bleeding)
HMB-TAF is designed as a prophylactic treatment for Hereditary Hemorrhagic Telangiectasia and disorders of hyperfibrinolysis
HMB-AT3 (Thrombosis)
HMB-AT3 is designed as a prophylactic treatment for antithrombin (AT) deficiency
