Study Details

Study Description

Brief Summary

There is currently no effective treatment for COVID-19 except best supportive care. The aim is assess the safety, tolerability and efficacy of convalescent plasma for treatment of patients with varying degrees of COVID-19 illness.

Condition or Disease Intervention/Treatment Phase
  • Biological: SARS-CoV-2 convalescent plasma
Phase 1/Phase 2

Detailed Description

Convalescent plasma has been shown to be safe and effective for treatment of several diseases. Preliminary data indicates that it is safe and effective for treatment of COVID-19. However, data is limited to small studies and case series on severely ill patients. The proposed study assesses the safety and efficacy earlier in the course of illness, in slightly less severe patients with the possibility of detecting less severe adverse events and the potential for early treatment to hinder the development of severe disease. Plasma is collected from consenting donors who have recovered from SARS-CoV-2.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Convalescent plasma treatment

All participants will receive a bag of convalescent plasma. The bag volume will be 180-200 ml. The first 10 patients will receive 1, 5, 10, 50 and 134 ml of plasma at 30 minute intervals while being closely monitored for adverse events, especially allergic reactions. The remaining twenty patients will receive the convalescent plasma as a slow infusion according to normal routines.

Biological: SARS-CoV-2 convalescent plasma
Treatment with convalescent plasma (180-200ml) from individuals who have recovered from SARS-CoV-2 infection

Outcome Measures

Primary Outcome Measures

  1. Disease progression [28 days]

    Decrease in progression to requiring non-invasive or invasive ventilation

Secondary Outcome Measures

  1. Adverse events (AE) [The reporting period for AEs starts at inclusion and ends at the final follow-up visit 2 months after inclusion.]

    Adverse reactions and serious adverse reactions. The safety of the intervention will be assessed with regard to AEs, baseline medical conditions, and findings from the physical examination and laboratory tests. Possible adverse events will be elicited using a modification and Swedish translation (appendix 6) of Common Terminology Criteria for Adverse Events v5.0 and they will be continuously reported to the sponsor. Adverse events related to convalescent plasma therapy shall be followed to assess reversibility.

  2. Time ro resolution of fever and symptoms [Until discharged from the hospital, up to 2 months]

    Measured daily until discharged from the hospital.

  3. Clearance of viraemia [Evaluated daily until discharge, at day 28, and last measurement taken at 6 months of follow-up after inclusion.]

    SARS-CoV-2 RNA detection by polymerase chain reaction (PCR) in blood or serum. Blood samples for immunological analyses and serology will be taken daily until discharge, on day 28, and at 6 months.

  4. Inflammatory parameter C-reactive protein (CRP) [Until discharged from the hospital, up to 2 months]

    Time to normalization of inflammatory parameter C-reactive protein (CRP). Blood sample for this marker will be taken daily until normalized or discharged from hospital.

  5. Inflammatory parameter white blood cell count [Until discharged from the hospital, up to 2 months]

    Time to normalization of inflammatory parameter white blood cell count (WBC). Blood sample for this marker will be taken daily until normalized or discharged from hospital.

  6. Inflammatory parameter haemoglobin (Hb) [Until discharged from the hospital, up to 2 months]

    Time to normalization of inflammatory parameter haemoglobin (Hb). Blood sample for this marker will be taken daily until normalized or discharged from hospital.

  7. Inflammatory parameter Pro-calcitonin [Until discharged from the hospital, up to 2 months]

    Time to normalization of inflammatory parameter Pro-calcitonin. Blood sample for this marker will be taken daily until normalized or discharged from hospital.

  8. Inflammatory parameter Creatine Kinase [Until discharged from the hospital, up to 2 months]

    Time to normalization of inflammatory parameter Creatine Kinase. Blood sample for this marker will be taken daily until normalized or discharged from hospital.

  9. Antibody response to SARS-CoV-2 [Evaluated daily until discharge, at day 28, and last measurement taken at 6 months of follow-up after inclusion.]

    Change in the antibody response to SARS-CoV-2 as measured in serum. Blood samples for immunological analyses and serology will be taken daily until discharge, on day 28, and at 6 months.
