Convalescent Plasma Therapy - Zurich Protocol (CPT-ZHP)

April 27, 2021 updated by: University of Zurich

A Phase i, Open-label, Single-centre Clinical Study to Evaluate Safety and Efficacy of Passive Immunization of High-risk SARS-CoV-2 Positive Patients With Convalescent Plasma Therapy

This is an open-label, single-center, phase I study to assess the safety and efficacy of convalescent plasma therapy (CPT) obtained from donors who were tested positive for SARS-CoV-2 and fully recovered from the infection and administered to patients who are infected with the new coronavirus and present dyspnea or a poor prognosis

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The outbreak of a new highly contagious and life-threatening infective disease was first reported in China in December 2019. Regardless of the undertaken containing measures, its spreading could not be effectively stopped and currently we are confronting the pandemic diffusion of a newly identified Coronavirus (SARS-CoV-2) (1). This causes a systemic disease, known as (Coronavirus Disease-19) COVID-19, characterised by a broad spectrum of clinical manifestations, including ineffective hyper-inflammation and severe pneumonia, with provisional epidemiologic data indicating a mortality rate of 0.1-15% (2). Do to the lack of vaccination, specific anti-virus sera or monoclonal antibodies, the therapeutic efforts to limit COVID-19 mostly rely on the empirical use of anti-viral drugs. Therefore, being the option of an active immunisation not available and because of the controversial efficacy of the available anti-viral therapies (3), we suggest the option of a passive immunisation for those patients who are infected with the new coronavirus and present dyspnea or a poor prognosis. The use of convalescent plasma, i.e. plasma obtained from donors who were tested positive for SARS-CoV-2 and fully recovered from the infection, could provide a rapid protection, limiting the observed evolution of COVID-19 towards life-threating manifestations (7-9).

When carried on according to standardised measures, the transfusion of plasma is highly safe (10-11) and we assume that products containing anti- SARS-CoV- 2 antibodies will provide the recipients a passive immunity through different mechanisms, including viral neutralisation, antibody-dependent cellular cytotoxicity and/or phagocytosis.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers
