Brief Summary:
The objectives of this study are to evaluate the safety, tolerability and efficacy of AT-527 in older subjects (ages 45-80 years) with moderate COVID-19 and risk factors for poor outcomes (such as obesity (BMI>30), hypertension, diabetes or asthma). Eligible subjects will be randomized to blinded AT-527 (nucleotide analog) tablets or matching placebo tablets to be administered orally for 5 days. Local supportive standard of care (SOC) will be allowed for all subjects. Efficacy and safety observations will be compared for treatment with active AT-527 tablets + SOC vs. placebo tablets + SOC.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 190 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Masking Description: Blinded
Primary Purpose: Treatment
Official Title: A Phase 2 Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety and Efficacy of AT-527 in Subjects With Moderate COVID-19
Actual Study Start Date : May 26, 2020
Estimated Primary Completion Date : December 2020
Estimated Study Completion Date : January 2021

Arm Intervention/treatment
Active Comparator: AT-527 + SOC Drug: AT-527
One 550 mg tablet of AT-527 administered every ~12 hours (twice a day) + SOC for a total of 5 days

Placebo Comparator: Placebo + SOC Other: Placebo
One placebo tablet administered every ~12 hours (twice a day) + SOC for a total of 5 days




Primary Outcome Measures :
  1. Proportions (active vs. placebo) of subjects with progressive respiratory insufficiency. [ Time Frame: Day 14 ]
    Progressive respiratory insufficiency defined as a ≥ 2-tier increase in respiratory support methods required to maintain satisfactory oxygenation (SpO2 ≥ 93%), using the 6-tier hierarchical scale of respiratory support methods

  2. Proportions (active vs. placebo) of subjects experiencing treatment-emergent adverse events [ Time Frame: Day 14 ]

Secondary Outcome Measures :
  1. Time to clinical recovery [ Time Frame: Day 14 ]
    Clinical recovery defined as time from randomization to disease resolution status on an 8 point Clinical Status scale

  2. Proportions (active vs. placebo) of subjects with respiratory failure or death [ Time Frame: Day 28 ]
