A Study of APL-9 in Adults With Mild to Moderate ARDS Due to COVID-19

• Status: Completed
• Trial end date: 2021-02-19
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to evaluate the safety and effectiveness of APL-9 in adults with mild to moderate ARDS (acute respiratory distress syndrome) caused by COVID-19 who are hospitalized and require supplemental oxygen therapy with or without mechanical ventilation.

It is thought that COVID-19 activates the complement system, part of the immune system that responds to infection or tissue damage, and increases inflammation in the lungs. APL-9 has been designed to inhibit or block activation of part of the complement pathway, and potentially reduce inflammation in the lungs.

Part 1 of the study is open-label to evaluate safety; all participants will receive APL-9 plus standard of care. Part 2 of the study is double-blind, randomized; participants will receive either APL-9 or the vehicle-control plus standard of care.

Criteria

Inclusion Criteria:

• Be at least 18 years of age at time of informed consent

• Diagnosis of active SARS CoV 2 infection using viral RNA or viral antigen within 7 days of screening

• Respiratory failure requiring oxygen supplementation or either invasive or noninvasive mechanical ventilation with PaO2/FiO2 ratio >100 mm Hg. Respiratory failure cannot be fully explained by cardiac failure or fluid overload.

Exclusion Criteria:

• Treatment with immune checkpoint inhibitors, or other immunomodulators within 3 months prior to study enrollment (however, treatment with convalescent plasma, steroids, IL-6 inhibitors, and antiviral agents is NOT excluded)

• Active bacterial, fungal, or parasitic infection

• History of neuromuscular degenerative disease (eg, amyotrophic lateral sclerosis, Duchenne muscular dystrophy, or multiple sclerosis)

• Current participation in an interventional clincial trial

• Subjects who have, at screening, been on mechanical ventilation for >7 days Have evidence of kidney and liver failure at screening

• Have a hereditary complement deficiency

• Pregnancy or breastfeeding
