Trial Outcomes & Findings for COVID-19 Outpatient Pragmatic Platform Study (COPPS) - Master Protocol (NCT NCT04662086)

NCT ID: NCT04662086

Last Updated: 2023-06-28

Results Overview

Change in shedding of SARS-CoV-2 virus through day 10 attained from self-collected nasal swab. Viral load (nucleic acid) was assessed by RT-PCR Ct over time, and is reported here as the average change in Ct values per day. Cycle threshold (Ct) denotes how many PCR cycles are required before the SARS-CoV-2 viral RNA reached a detectable level. Higher Ct values correspond to lower viral copy numbers. For reference, Ct values of 20 correspond to \~2.12 x 106 viral copies per milliliter, while a Ct value of 40 is undetectable and is considered the lower limit of detection of this RT-PCR test for SARS-CoV-2.

Time from randomization to sustained symptom resolution assessed over a 28-day period. Resolution is defined as the first day where no symptoms are self-reported on all succeeding days through and including day 28, not including sense of taste or smell, and defining recovery for fatigue and cough as mild or none.
