Los Angeles, Calif. – The AIDS Clinical Trials Group (ACTG), the largest global HIV research network, today announced that the Camostat treatment group of the COVID-19 outpatient treatment study, ACTIV-2 Outpatient Monoclonal Antibodies and Other Therapies Trial, will not move to phase 3. ACTIV-2 includes both phase 2 and phase 3 evaluations of multiple investigational agents for treating early COVID-19 in a single trial. For information about the trial, please visit the study website.
Camostat, provided by Sagent Pharmaceuticals (a Nichi-Iko Group Company), is an orally administered protease inhibitor that was dosed as 200 mg every six hours for seven days. The Camostat arm of ACTIV-2 completed phase 2 enrollment with 224 participants on April 26, 2021. When the Therapeutic and Prevention Data and Safety Monitoring Board (DSMB) met on June 14, 2021 to review the data and determine whether Camostat would advance to phase 3, they determined that while there were no safety concerns, the phase 2 data failed to meet the criteria for graduation (which is based on demonstrating early changes in viral shedding or improvement in symptoms). Participants enrolled in phase 2 in the Camostat treatment group will continue to be followed per the ACTIV-2 protocol.
ACTIV-2 is a randomized, blinded, controlled adaptive platform that allows promising therapies to be added and removed over the course of the study to efficiently test a variety of new agents against placebo within the same trial infrastructure. It is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), which also funds the ACTG. ACTIV-2 is part of NIH’s Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV), a public-private partnership program to create a coordinated research strategy that prioritizes and speeds development of the most promising treatments and vaccines. It also receives support from the Federal COVID Response-Therapeutics, the U.S. government’s multi-agency effort to accelerate the development, manufacturing, and distribution of COVID-19 vaccines, therapeutics, and diagnostics.
