Norfolk, VA, February 16, 2021ReAlta Life Sciences, Inc. (“ReAlta”), a company addressing life-threatening diseases through harnessing the power of the immune system, today announced that it has dosed the first subject in a Phase 1 study to evaluate RLS-0071 in healthy volunteers. RLS-0071 is the lead compound of a platform of proprietary engineered peptides that leverage a billion years of evolution with a dual targeting mechanism that inhibits components of the complement cascade and cellular inflammatory processes. RLS-0071 is in development for treatment of Acute Lung Injury (ALI) as a result of viral infections such as COVID-19, RSV, and influenza.

The initiation of this trial is a significant milestone for ReAlta as we are advancing RLS-0071 in development to treat a number of acute hospital-based indications with our novel dual targeting mechanism,” said Ulrich Thienel, M.D., Ph.D., ReAlta’s Chief Executive Officer. “The results from our healthy volunteers study will inform our ongoing ALI study in hospitalized COVID-19 patients, as well as future programs in hypoxic-ischemic encephalopathy in newborns and hemolytic transfusion reactions. We look forward to obtaining data from this study as it progresses and continues to support our other programs.”

The Phase 1 trial is a single ascending dose randomized, double-blind, placebo-controlled, adaptive-design study to evaluate the safety, tolerability, PK and PD of RLS-0071 in healthy subjects.
