Official Title: A Phase 2 Randomized, Single-Blind Study of a Single Dose of Peginterferon Lambda-1a (Lambda) Compared With Placebo in Outpatients With Mild COVID-19
Actual Study Start Date : April 25, 2020
Actual Primary Completion Date : August 14, 2020
Actual Study Completion Date : May 6, 2021

Arm Intervention/treatment
Experimental: Study drug Peginterferon Lambda-1a
Study participants assigned to study drug will receive a single subcutaneous dose of Peginterferon Lambda-1a in addition to standard of care treatment.
Drug: Peginterferon Lambda-1a
Peginterferon Lambda-1a (180 ug subcutaneous injection) single dose along with Standard of Care

Placebo Comparator: Placebo injection
Study participants will receive a placebo along with the standard of care treatment.
Other: Placebo
Placebo subcutaneous injection along with Standard of Care Treatment for COVID-19 Infection




Primary Outcome Measures :
  1. Duration Until Viral Shedding Cessation [ Time Frame: Assessed for up to 28 days ]
    Time to first of two consecutive negative respiratory secretions obtained by oropharyngeal and/or anterior nare swabs for SARS-CoV-2 by qRT-PCR.


Secondary Outcome Measures :
  1. Change in Sars-CoV-2 Viral Load [ Time Frame: baseline, day 14 ]
    Log10 Oropharyngeal viral load over time, mean change at day 14 (SD). Sars-CoV-2 RNA level in oropharyngeal and/or anterior nare swabs collected daily.

  2. Area Under the Curve of SARS-COV-2 Viral Load [ Time Frame: baseline through day 14 ]
    Log10 viral load area under the curve through day 14, median (IQR). Area under the curve of SARS-CoV-2 viral load in oropharyngeal and/or anterior nare swabs collected daily.

  3. Duration Until Resolution of Symptoms [ Time Frame: Up to 28 days ]
    Duration until resolution of symptoms in days, median (95% CI). Time to alleviation of all symptoms (fever, chills, cough, nasal congestion, muscle pains), defined as the time from initiation of treatment until all symptoms are rated as absent or mild in symptomatic patients.

  4. Count of Participants Requiring Emergency Department Visits or Hospitalizations Within 28 Days of Initiation of Treatment [ Time Frame: 28 days ]
