COVID - 19 Clinical Trial
Official title:
A Phase II Safety and Tolerability, Inter-patient Pre-defined Dose Study of Ex-vivo Expanded Allogeneic γδ T-lymphocytes (TCB008) in Patients Diagnosed With COVID-19
A Phase II safety and tolerability study of expanded gamma delta T cell lymphocytes (TCB008) in patients diagnosed with COVID-19.
The aim of this Phase II study is to evaluate the safety and tolerability of ex-vivo expanded gamma delta T-cells (TCB008) manufactured from a single allogeneic unmatched or partially, randomly matched, unrelated donor, in patients with COVID-19. The trial is designed to identify an optimal, safe dose of allogeneic γδ T cells in a population of patients with COVID-19. There will be 4 patient Cohorts. Cohorts 1 - 3 will receive a pre-defined dosing schedule, with Cohort 4 being treated with a dose selected upon completion of the first 3 Cohorts. In order to investigate immunogenicity assessment/sensitisation effects, patients in the expansion cohort who do not experience adverse reactions meeting dose limiting toxicity (DLT) criteria after the first administration will receive re-infusion with the same dose on Day 10 after the first infusion. ;
