A Multicenter, Adaptive, Randomized Blinded Controlled Trial of the Safety and Efficacy of Investigational Therapeutics for the Treatment of COVID-19 in Hospitalized Adults (ACTT-3)
In Brief
A Phase 3 clinical trial evaluating Interferon beta-1a, Placebo, and 1 other intervention for COVID-19. Completed, enrolled 969 participants across 64 sites in 5 countries.
Detailed Summary
ACTT-3 will evaluate the combination of interferon beta-1a and remdesivir compared to remdesivir alone. Subjects will be assessed daily while hospitalized. If the subjects are discharged from the hospital, they will have a study visit at Days 15, 22, and 29. For discharged subjects, it is preferred that the Day 15 and 29 visits are in person to obtain safety laboratory tests and oropharyngeal (OP) swab and blood (serum only) samples for secondary research as well as clinical outcome data. However, infection control or other restrictions may limit the ability of the subject to return to the clinic. In this case, these visits may be conducted by phone, and only clinical data will be obtained. The Day 22 visit does not have laboratory tests or collection of samples and is conducted by phone. The primary outcome is time to recovery by Day 29.

Timeline
Interventions
Rebif (R) is a purified 166 amino acid human interferon beta glycoprotein with an amino acid sequence identical to natural fibroblast derived human interferon beta. Each 0.5 mL prefilled syringe contains 44 mcg of interferon beta-1a, 4 mg human albumin, USP; 27.3 mg mannitol, USP; 0.4 mg sodium acetate; and water for injection, USP.
The interferon beta-1a placebo contains either 0.5 mL 0.9% normal saline or 0.5 mL sterile water for injection.
Drug Remdesivir is a single diastereomer monophosphoramidate prodrug designed for the intracellular delivery of a modified adenine nucleoside analog GS-441524. In addition to the active ingredient, the lyophilized formulation of Remdesivir contains the following inactive ingredients: water for injection, sulfobutylether beta-cyclodextrin sodium (SBECD), and hydrochloric acid and/or sodium hydroxide.
