COVIC-19: Early High-Titre Convalescent Plasma in Clinically Vulnerable Individuals With Mild COVID-19
Study Details
Study Description
Brief Summary
-
Research Question: Does convalescent plasma (CCP) collected from donors who have recovered from COVID-19 and who have a very high titre of anti-SARS-CoV-2 antibodies reduce the risk of hospitalisation (for COVID-19) or death in patients with early symptoms of acute COVID-19 who are vulnerable to this disease compared to standard of care?
-
Study product: Very high antibody titre COVID-19 convalescent plasma collected more than 15 days after end of symptoms in COVID-19 patients who also had received at least one dose of a SARS-CoV-2 vaccine.
-
Methodology: Multicentre, randomised, open-label, adaptive superiority trial: COVID-19 very high neutralizing Ab titre convalescent plasma vs standard care in 2 cohorts of vulnerable patients (cohort 1: elderly (≥ 70 years) and younger with comorbidities, cohort 2: immunosuppressed patients).
-
Study phase: Phase 3
-
Intervention: Two units of high antibody titre COVID-19 convalescent plasma to individuals randomised to the intervention group, 2 units from 2 different donors, preferably transfused on the same day. Plasma provided by convalescent vaccinated donors with a minimum antibody titre of 1:640 against delta variant (B1.617.2)
-
Randomisation: 1:1 (standard of care + convalescent plasma vs. standard of care) stratified by centre (cohorts 1 and 2)

Detailed Description
COVIC-19 is a multicentre international, randomised, open-label adaptive superiority phase III trial to evaluate the efficacy and safety of COVID-19 convalescent plasma in the treatment of COVID-19. It is conducted in a harmonized approach in different countries in Europe.
The study is randomizing adult COVID-19 patients to one of two arms (1:1 ratio): standard of care or standard of care and very high neutralizing Ab titre convalescent plasma. Randomization will be stratified by centre and by patient cohort. The control group will receive 'standard care' therapy. Neither blinding nor placebo will be used to avoid unnecessary intravenous access.
Standard of care therapy may include anti-SARS-CoV-2 specific medication listed as authorized in the protocol. Centres should ensure that medications used as standard of care are used similarly for patients in both treatment arms.
Participating patients will be included in 2 cohorts of vulnerable patients (cohort 1:
elderly (≥ 70 years) and younger with comorbidities (cohort 1: < 70 with comorbidities), cohort 2: immunosuppressed patients).
All subjects will undergo a series of efficacy and safety assessments, including laboratory assays. Subjects will be assessed at baseline, and at Days 3, 14, 28, 90 and 180.
Nasopharyngeal swabs (NP) or lower respiratory tract samples will be obtained at D1 (pre-treatment), and at D3, D14 and D28 (and monthly in case of positivity until of clearance) for cohort 2.
Blood samples will be obtained at D1, D14 and D28 and on the day of hospitalization (if applicable).
The trial is sponsored by the University Hospital of Besançon in France, the German Red Cross in Germany and the NHSBT in the United Kingdom.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Active Comparator: Current standard of care Standard of care therapy may include anti-SARS-CoV-2 specific medication such as, but not limited to: Casirivimab Casirivimab / Imdevimab (REGN-COV2 or Ronapreve) Imdevimab Sotrovimab (Xevudy) Tixagevimab / Cilgavimab (Evusheld) Molnupiravir (MK-4482) Nirmatrevlir / Ritonavir (Paxlovid) Remdesivir Centres should ensure that medications used as standard of care are used similarly for patients in both treatment arms. |
Other: Current standard of care
Standard of care therapy may include anti-SARS-CoV-2 specific medication such as, but not limited to:
Casirivimab-imdevimab (REGN-COV2 or Ronapreve)
Regdanvimab (Regkirona)
Bamlanivimab / Etesimab
Sotrovimab (Xevudy) Centres should ensure that medications used as standard of care are used similarly for patients in both treatment arms.
|
Experimental: Current standard of care and convalescent plasma Current standard of care and the infusion of two plasma units provided by two COVID-19 convalescent patients. |
Biological: COVID-19 convalescent and vaccinated plasma
ABO compatible convalescent plasma infused intravenously on study day 1 (as soon as possible after randomisation) and the second on day 1 or day 2. Plasma obtained by apheresis from donors who have recovered from COVID-19 infection (at least 14 days after recovery) and have been vaccinated (at least 3 weeks after first dose of vaccine). A combination of both a SARS-CoV-infection and a SARS-CoV-2 vaccination of the donor is required - irrespective of the sequence of infection and vaccination. As far as the availability of CCP units allows, the two plasma units should have been donated by two different convalescents.

Outcome Measures
Primary Outcome Measures
- Proportion of participants with hospitalisation with O2 support or death [Day 14]
Proportion of participants with (1) at least one overnight stay in hospital for progressive COVID-19 symptoms requiring O2 support*, or (2) who died * O2 support requirement based on O2 saturation level on room air ≤ 93 % and/or RR > 30
Secondary Outcome Measures
- Proportion of participants with hospitalisation for progressive COVID-19 symptoms requiring O2 support, or death [Day 28]
- Proportion of patients with hospitalisation and/or additional treatment for COVID-19 [Day 28]
- All-cause mortality [Day 28, 90, 180]
- Proportion of patients with supplemental oxygen [Day 14, 28]
- Proportion of patients with non-invasive ventilation [Day 14, 28]
- Proportion of patients with intubation and mechanical ventilation [Day 14, 28]
- Change in 10-point WHO Clinical Progression Scale score [Day 14, 28]
The 10-point WHO clinical progression scale ranges from 0 to 10 (0: uninfected; 10: death)
- Duration of hospital admission censored at 28 days [Day 28]
- Proportion of patients with admission to ITU [Day 14, 28]
- Duration of ITU admission censored at 28 days [Day 28]

A quality of life index ranging from less than 0 (worse than death) to 1 (full health) is derived from the answers to the questionnaires.
