Brief summary

The trial is testing a new therapy to treat the virus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19. The new treatment is called T cell immunotherapy. It aims to use T cells, a type of immune cell, to fight disease. This therapy is given via infusion into the bloodstream (intravenous infusion). Researchers at QIMR Berghofer Medical Research Institute have grown T cell therapies from blood samples donated by healthy people who have an immune response against SARS-CoV-2. These blood donors tested positive for SARS-CoV-2 more than a year before their blood donation, so their immune system has a memory of the virus and is able to fight it. Their anti-viral T cells have been grown in the laboratory to large numbers, and then frozen in single doses for the treatment of future patients. The main purpose of this clinical trial is to see if the T cell therapy is safe for people who have tested positive for SARS-CoV-2 and are at risk of developing severe COVID-19 because they have either received a transplant, chemotherapy, or a treatment that suppresses their immune system. We will recruit 20 participants in the trial. They will be matched with the most suitable batch of T cell therapy and then receive two intravenous infusions of T cells approximately 2 weeks apart at Royal Brisbane and Women’s Hospital. Monitoring of participants includes physical assessments, blood tests and nasal swabs. There will be five study visits over an approximately 3-month period.

Interventions

‘SARS-CoV-2-specific T cells THI-COV’, and consists of T cells targeting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Investigational Product (IP) has been be generated at Q-Gen Cell Therapeutics from the peripheral blood of healthy donors recruited through QIMR Berghofer project P3684. Recruited donors are now convalescent following previous exposure to SARS-CoV-2 infection. Batches of IP will be selected for participants based on human leukocyte antigen matching. The safety of

Recruited donors are now convalescent following previous exposure to SARS-CoV-2 infection. Batches of IP will be selected for participants based on human leukocyte antigen matching. The safety of the IP in a therapeutic setting will be tested in 20 patients who have SARS-CoV-2 and are at high risk of developing severe COVID-19 due to immunosuppression. Participants will be recruited from Royal Brisbane and Women’s Hospital. Two intravenous infusions of 4 × 10^7 cells/infusion will be given 14 days (plus or minus 3 days) apart. Participants will be assessed on Days 0, 14, 28 and 84 for safety, and immunological and virological studies will be conducted. The IP will be administered intravenously over 5–10 min by a qualified person (e.g. registered nurse or clinician). This will be followed by a saline flush, which will take an additional 5–10 min.
