Clinical Trial Summary

The novel coronavirus disease (COVID-19), which began in Wuhan, China, in December 2019, has been declared to be a pandemic by the World Health Organization (WHO), Caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), COVID-19 has resulted in 1,781,127 cases and 108,994 deaths globally (till 12th April, 2020), affecting 199 countries and 2 international conveyances. US FDA has recently approved Convalescent Plasma from patients recovered from COVID 19 for the treatment of severe or life threatening COVID-19 infections. In a small case series, five critically ill COVID-19 patients with ARDS were treated with convalescent plasma containing neutralizing antibodies. Infusion of plasma was followed by improvement in clinical status in all five patients, with no deaths and the study reported that three patients were discharged, whilst two continued to be stable on mechanical ventilation. We designed this phase II, open label, randomized clinical trial with the primary objective to assess the safety and efficacy of the therapy in the second stage.


Clinical Trial Description

The study will be conducted over the period of one year on 100 Hospitalized, COVID-19 patients, fulfill the inclusion and exclusion criteria, and are admitted for care at COVID-19 management facilities in Max healthcare Hospital will be eligible for inclusion in the trial. This Phase II, open label, randomized controlled trial. Consecutive patients meeting the inclusion-exclusion criteria and providing informed consent will be randomly assigned to the test and the control group using random numbers generated by randomization.com. Patients in the test group will receive convalescent plasma and the control group will be on standard care.

COVID-19 convalescent plasma will be collected from recovered individuals if they are eligible to donate blood. For infusion of plasma existing SOP of the wards w.r.t transfusion of FFP should be followed with special care to monitor these patients during and post-24 hours of transfusion. An ABO compatible plasma bag of approx. 200ml will be issued maintaining all the blood bank records after thawing at 37 degree Celsius. The first plasma transfusion may be followed by one or two additional doses of 200 ml at 24 hours interval according to disease severity and tolerance of the infusions. Baseline data about the demography, clinical presentations, ongoing medical therapy, and clinical history of participants in both arms will be collected and compared. Response to convalescent plasma will be coded as a binary outcome - based on whether the composite primary end point is met or not. Adverse events associated with infusion of convalescent plasma will also be descriptively summarized and compared with the adverse events experienced by participants receiving standard of care.

Eligibility of Potential Donor

1. Only males and nulliparous female donors of weight > 55 kgs will be included.

2. Donor eligibility criteria for whole blood donation as per the departmental SOP will be followed in accordance to the Drugs & Cosmetics Act 1940 and rules 1945 therein (as amended till March 2020). Donor will be screened, followed by brief physical examination.

3. Donors not fit to donate blood based on the history and examination will be deferred and excluded from plasma donor pool for a time period specified by country regulation & departmental SOPs.

4. In addition to the aforementioned donor eligibility criteria, two EDTA samples (5 ml each) and one plain sample (5 ml) will be drawn for the following pre-donation tests as required for convalescent plasmapheresis (CPP).

- Blood group and antibody screening - Antibody screen positive donors will be deferred.

- Complete blood count including Hb, Hct, Platelet count, Total and differential leucocyte count. Donors with Hb>12.5g/dl, platelet count >1, 50,000 per microliter of blood and TLC within normal limits will be accepted.

- Screening for HIV, HBV and HCV by serology and NAT. Donor negative by both the tests will be included.

- Screening for syphilis and malaria by serology. Negative donors will be included

- Total serum protein. Donors with total serum protein > 6gm/dl will be accepted (as per Drugs and Cosmetics (Second Amendment) Rules, 2020)

- Titration of anti-COVID-19 (both IgG and IgM) antibodies and SARS- CoV-2 neutralizing antibodies may be done depending on availability of facilities at the time of testing. (Desired titers for IgG antibodies >1024 or neutralizing antibodies >40) doubling dilution of donor serum will be done and titration will be done using ELISA. If not done at the time of plasma collection the donor samples will be stored in aliquots at <-80° C to be tested at a later date.

- Molecular test for COVID-19 either from nasopharyngeal swab specimens or blood may be done depending on availability of tests. Donors positive will be deferred. ;
