Study Description

Brief Summary:

A Phase 2 study to evaluate the safety and preliminary efficacy of ATYR1923, compared to placebo, in hospitalized patients with SARS-CoV-2 (COVID-19) severe pneumonia not requiring mechanical ventilation

Condition or disease	Intervention/treatment	Phase
SARS-CoV-2 (COVID-19) Severe Pneumonia	Drug: ATYR1923 1 mg/kg; Drug: ATYR1923 3 mg/kg; Drug: Placebo	Phase 2

Study Design

• Study Type: Interventional (Clinical Trial)
• Actual Enrollment: 32 participants
• Allocation: Randomized
• Intervention Model: Parallel Assignment
• Intervention Model Description: Patients will be randomized 1:1:1 to a single IV dose of ATYR1923 1 mg/kg, ATYR1923 3 mg/kg, or placebo.
• Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
• Masking Description: The Investigator, Sponsor, and patient will be blinded to treatment assignment; study center pharmacy personnel will be unblinded.
• Primary Purpose: Treatment
• Official Title: A Randomized Double-blind Placebo-controlled Study to Evaluate the Safety and Efficacy of ATYR1923 In Adult Patients With Severe Pneumonia Related to SARS-CoV-2 Infection (COVID-19)
• Actual Study Start Date: June 12, 2020
• Actual Primary Completion Date: December 21, 2020
• Actual Study Completion Date: December 21, 2020

Secondary Outcome Measures :

1. Time to hospital discharge [ Time Frame: Baseline through Day 60 ]
2. Time to recovery (World Health Organization [WHO] Ordinal Scale score ≤3) [ Time Frame: Baseline through Day 60 ]
3. Proportion of patients achieving recovery by Day 14 and Day 28 [ Time Frame: Baseline through Day 14 and Day 28 ]
4. Duration of supplemental oxygen (O2) requirement [ Time Frame: Baseline through Day 60 ]
5. Number of days with fever (temperature >100.4ºF [38.0ºC]) [ Time Frame: Baseline through Day 14 or discharge ]
6. Change from baseline in World Health Organization (WHO) Ordinal Scale score on Days 5, 7, 14, 28, and 60 [ Time Frame: Baseline through Day 60 ]
7. Time to improvement from inpatient hospital admission based on at least a 1 point reduction in WHO Ordinal Scale score [ Time Frame: Baseline through Day 60 ]
8. All-cause mortality at Days 14, 28, and 60 [ Time Frame: Baseline through Day 60 ]
