Clinical Trial Summary

AECOPD is a major cause of hospital admission and mortality. They contribute to long-term decline in lung function, physical capacity, and quality of life (QoL). RLS-0071 is a novel peptide being developed for the treatment of AECOPD. This study is designed to evaluate the safety and tolerability of RLS-0071 in the treatment of adults with moderate exacerbations of COPD.

Description:

This is a randomized, double-blind, placebo controlled trial in hospitalized participants with Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) to evaluate the safety, tolerability, preliminary efficacy, PK, and PD of RLS-0071 compared to Placebo in the treatment of AECOPD. The dosing regimen will be 3 times a day for at least 3 days and up to 5 days total if still hospitalized. Participants will be followed for efficacy and safety for 30 and 60 days after the final dose. RLS-0071 or Placebo will be given as add-on therapy to SOC management for acute exacerbations of COPD.
