ARCA Biopharma Expects Data Readout From Mid-Stage COVID-19 Trial In Q1 2022

ARCA biopharma Inc (NASDAQ:ABIO) has completed enrollment of 160 patients in ASPEN-COVID-19 Phase 2b trial evaluating rNAPc2 for patients hospitalized with COVID-19.

* The Company anticipates reporting topline data in Q1 of 2022.

* The trial's primary endpoint is the change in D-dimer level from baseline to Day 8 relative to standard of care heparin.

* D-dimer is a biomarker commonly used for assessing coagulation activation, which is elevated in approximately 40% to 75% of hospitalized COVID-19 patients and is associated with adverse clinical outcomes.

* Heparin is an anticoagulant commonly given to any patient hospitalized for COVID-19.

* Other objectives of Phase 2b are to assess safety, determine the optimal dose regimen for a potential Phase 3 trial and evaluate multiple additional clinical endpoints.

* rNAPc2 is a small recombinant protein. It is a potent, selective inhibitor of tissue factor (TF), which plays a central role in the inflammatory response to viral infections.
