Convalescent Plasma Therapy - Zurich Protocol (CPT-ZHP)
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
Přehled studie
Detailní popis
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.

- Intention to become pregnant during the course of the study
- Lack of safe contraception, defined as: Female participants of childbearing potential, not using and not willing to continue using a medically reliable method of contraception for the entire study duration, such as oral, injectable, or implantable contraceptives, or intrauterine contraceptive devices, or who are not using any other method considered sufficiently reliable by the investigator in individual cases. Please note that female participants who are surgically sterilised / hysterectomised or post-menopausal for longer than 2 years are not considered as being of child bearing potential
