Advancing the development of treatments for patients 

with pulmonary hypertension and interstitial lung disease

Our Mission

Halo is a clinical-stage biotechnology company with a mission to create first-in-class, disease-modifying therapies for the treatment of inflammatory and fibrotic diseases. Our first indication is pulmonary hypertension and interstitial lung disease.






About Halo

Our Science

The ECM in Disease

We are building a differentiated pipeline based on novel insights into how  extracellular matrix (ECM) dysregulation drives disease 


Our primary target is Hyaluronan (HA), a key component of the ECM


Alterations to HA are associated with a variety of conditions characterized by inflammation and fibrosis, including pulmonary hypertension, pulmonary fibrosis, and liver fibrosis


Our aim is to use cutting edge advances in research and development to optimize the modulation of hyaluronan and deliver safe and effective medicines for patients

About Our Science

Our Pipeline

Novel target for pulmonary hypertension

Our lead pipeline candidate, H1614, is a reformulation of 4-methylumbelliferone, with the potential to be a  first- and best-in-class hyaluronan (HA) remodeling agent for the treatment of patients with Group 3 pulmonary hypertension.


Preclinical and clinical data suggest that targeting the HA pathway can address the inflammation, fibrosis, and vascular remodeling associated with disease progression.
