ABOUT ESPERO (Espero BioPharma)

We named our company Espero because it means hope. And that’s what we seek to provide everyone who takes our innovative cardiovascular medicines. Hope for improved health and hope for a better tomorrow.

Espero BioPharma is a pharmaceutical company focused on the development of drugs for unmet needs in thrombosis and cardiac rhythm control. The Company is developing tecarfarin for patients requiring chronic anticoagulation and an anti-arrhythmic drug (AAD) program to treat atrial fibrillation (AFib). Tecarfarin and our AAD compounds were designed so that metabolic clearance is not hindered by the body, creating the potential for increased efficacy with a superior safety profile.

Espero Biopharma’s late-clinical stage oral anticoagulant candidate – Tecarfarin – addresses a major unmet need – a medication with potentially fewer adverse and fatal drug reactions and expected compatibility with treatment plans for patients with prosthetic heart valves.

Espero BioPharma is exploring its portfolio of small molecules as therapies to treat cardiac arrhythmias, with particular interest in atrial fibrillation and ventricular tachycardias and fibrillation.  An arrhythmia can occur in either chamber of the heart, atrium or ventricle, and is due to abnormal electrical signals. When arrhythmias result in disabling symptoms or a device firing, efforts to prevent future arrhythmia episodes may include ablative therapy or drug therapy. Ablation is of limited success, often temporary, and is often augmented with drug therapy.

Educating the Community
