CCAP is an investigator-initiated multicentre, randomized, double blinded, placebo-controlled trial, which aims to assess the safety and efficacy of treatment with convalescent plasma for patients with moderate-severe COVID-19.
Participants will be randomized 2:1 to two parallel treatment arms: Convalescent plasma, and intravenous placebo.
Primary outcome is a composite endpoint of all-cause mortality or need of invasive mechanical ventilation up to 28 days.
Condition or disease | Intervention/treatment | Phase |
---|---|---|
COVID Corona Virus Infection Viral Pneumonia | Biological: Convalescent anti-SARS-CoV-2 plasma Other: Infusion placebo | Phase 3 |
The study is a randomized, double blinded, placebo-controlled, multicenter study with two parallel treatment arms consisting of either convalescent plasma or intravenous placebo. We plan to enroll a total of 1100 patients yielding a statistical power of 80 % to show a 30% relative reduction in risk of mechanical ventilation or death at day 28. Patients with confirmed COVID-19 infection and signs compatible with pneumonia will be enrolled in the study. The participants will be randomized 2:1 to the parallel treatment arms, and receive either single dose infusion treatment.
The primary outcome is a composite endpoint of all-cause mortality or need of invasive mechanical ventilation up to 28 days. Interim analysis will be performed frequently.
As new knowledge of treatment options for COVID-19 have emerged, the treatment arms including sarilumab, baricitininb, hydroxychloroquine and oral placebo have been terminated.
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 147 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Adaptive multi-arm trial comparing convalescent plasma against control group. Interim analyses are included at 300 and 700 included participants to compare the effect and safety of the experimental treatment to control (placebo). The results of the interim analyses are used to decide if the treatments should be discontinued due to either futility or harm. The study is discontinued if either of the predefined stopping criteria are met. Additional experimental treatments may be added as they become available. Any efficacious treatment identified in this or any other high-quality RCT may become the new SOC after consensus by national and international societies, and, thus, the control arm will change accordingly and in parallel. |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
Masking Description: | Both convalescent plasma and placebo will be administered via a colored intravenous line with a colored sleeve disguising the fluid bag. In order to achieve blinding of participants and treating personnel, patients randomized to active treatment will also receive placebo treatment. |

- All-cause mortality or need of invasive mechanical ventilation [ Time Frame: 28 days ]Composite outcome
- Frequency of adverse events [ Time Frame: 90 days ]Number of participants with adverse events with possible relation to study drug
- Frequency of severe adverse events [ Time Frame: 90 days ]Number of participants with serious adverse events according to International Council of Harmonisation-Good Clinical Practice (ICH-GCP) guidelines

- Ventilator-free days [ Time Frame: 28 days ]Number of days without mechanical ventilation
- Organ failure-free days [ Time Frame: 28 days ]Number of days without organ-failure
- Duration of ICU stay [ Time Frame: 90 days ]Number of days in ICU
- Mortality rate [ Time Frame: 7, 14, 21, 28 and 90 days ]Number of deaths by any cause
- Length of hospital stay [ Time Frame: 90 days ]Days from the date of hospital admission for COVID-19 to the date of discharge
- Duration of supplemental oxygen [ Time Frame: 90 days ]Days requiring supplement oxygen
