Convalescent Methylene Blue Treated (MBT) Plasma for Early Treatment in Non-hospitalised Mild or Moderate COVID-19 Patients: a Randomized Double Blind Study (COnV-ert)
In Brief
A Phase 2 clinical trial evaluating Convalescent anti-SARS-CoV-2 MBT plasma and Control Group for SARS-CoV-2 Infection and Safety and Efficacy. Completed, enrolled 384 participants across 4 sites.
Detailed Summary
This is a prospective, randomized (1:1), double blind study of Convalescent anti-SARS-CoV-2 MBT Plasma (also known as convalescent plasma) plus standard medical treatment (SMT) versus placebo plus SMT in mild or moderate COVID-19 patients who are non-hospitalised. Subjects with confirmed infection by SARS-CoV-2 will receive SMT plus a total of 200-300 mL of convalescent plasma that has been pathogen-inactivated using MBT or placebo. Approximately 474 individuals will be randomized (1:1) with an interim analysis after the first 60 subjects (30 in each arm). The sample size will be re-assessed upon interim analysis. Approximately 135 individuals from selected study sites will be included in the substudy to assess the immune response and the methods of sampling.

Approximately 135 individuals from selected study sites will be included in the substudy to assess the immune response and the methods of sampling. The investigational product will be administered by IV infusion at baseline. Participants will continue their standard medical treatment (SMT) for SARS-CoV-2 infection as prescribed by their regular physician. If applicable, SMT may be modified during the study, depending on personal requirements, the severity and progression of the disease, and need for hospitalization. Subjects' participation (from inclusion/baseline visit to the end-of-study visit) will be up to 60 days.

Interventions
Subjects randomized to combination convalescent anti-SARS-CoV-2 MBT plasma plus SMT will undergo an ABO compatibility test and will receive a single infusion of 200 to 300 ml of ABO-compatible convalescent plasma
Subjects randomized to placebo plus SMT will receive one infusion of 200 to 300ml of sterile saline solution 0.9%.
