Covid19 Clinical Trial

Official title: An International Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial of the Safety and Efficacy of Anti-Coronavirus Hyperimmune Intravenous Immunoglobulin for the Treatment of Adult Outpatients in Early Stages of COVID-19

Status Recruiting

Clinical Trial Summary

The primary objective of the Outpatient Treatment with Anti-Coronavirus Immunoglobulin (OTAC) (INSIGHT 012) trial is to compare the safety and efficacy of a single infusion of anti-COVID-19 hyperimmune intravenous immunoglobulin (hIVIG) versus placebo among adults with recently diagnosed severe acute respiratory syndrome - coronavirus 2 (SARS-CoV2) infection who do not require hospitalization. The primary endpoint of this double-blind randomized trial is a five-category ordinal outcome that assesses the participant's clinical status seven days after the infusion of hIVIG or placebo. 1. Asymptomatic and no limitations in usual activity due to COVID-19 2. Mild COVID-19 illness or minor limitations to usual activity 3. Moderate COVID-19 illness and with major limitations to usual activity 4. Severe COVID-19 or serious disease manifestation from COVID-19 5. Critical illness from COVID-19 or Death Two strata of participants will be identified for analysis purposes. Stratum 2 will be participants who receive direct-acting antivirals (DAAs) or other anti-SARS-CoV2 agents that are approved/available and recommended for use as part of standard of care (SOC), estimated to be about 20% of participants. Stratum 1 will be participants who do not receive this agents, estimated to be about 80% of participants.

Clinical Trial Description

The primary objective will be addressed by testing two hypotheses aimed at assessing whether hIVIG + standard of care (SOC) is superior to placebo + SOC for the primary ordinal endpoint at Day 7. These hypotheses will be tested for the following two groups: a) among all randomized participants (stratum 1 and 2), and b) among only participants enrolled in stratum 1. For the primary analysis, overall type 1 error will be controlled at 5% by using a 2-sided significance level of 0.035 for each hypothesis. This significance level was obtained using the correlation between the test statistics for the proportional log odds ratio for all randomized participants and for this log odds ratio for those in stratum 1. This correlation was determined to be 0.895. With this approach hIVIG will be considered superior to placebo if either of the two hypotheses is rejected. Participants will be randomized to a single infusion of an hIVIG product or placebo in a 1:1 allocation. Randomization will be stratified by study site pharmacy and the two SOC strata. ;
