Bringing Optimised COVID-19 Vaccine Schedules To ImmunoCompromised Populations (BOOST-IC): an Adaptive Randomised Controlled Clinical Trial
Bringing Optimised COVID-19 Vaccine Schedules To ImmunoCompromised Populations (BOOST-IC): an Adaptive Randomised Controlled Clinical Trial

NCT05556720

Active Not RecruitingPhase 3

Sponsor: Monash University

Conditions: HIV, Organ Transplantation, Lymphoma, Non-Hodgkin, Chronic Lymphocytic Leukemia, Multiple Myeloma

Interventions: Pfizer Bivalent COVID-19 Vaccine, Moderna Bivalent mRNA vaccine

Countries: Australia

Despite the greater risk of adverse COVID-19 outcomes, antibody and cell-mediated immune responses to COVID-19 vaccines vary amongst immunocompromised (IC) people and are poorly defined. IC hosts were largely excluded from the COVID-19 vaccine registration trials, though many countries recommend additional and booster doses of vaccination in this group. BOOST-IC is an adaptive randomised clinical trial (RCT) to assess the immunogenicity and safety of additional COVID-19 vaccine doses in immunocompromised (IC) people, including people with HIV, solid organ transplants (SOT) recipients or those with haematological malignancies. Briefly, the study aims to generate high-quality evidence on the immunogenicity and safety of alternative COVID-19 booster strategies against SARS-CoV-2 for IC people in Australia.

Eligibility criteria
Inclusion Criteria:

* Able to give informed consent and undertake study procedures
* Age ≥16 years old
* Have completed at least 3 months prior, 3- to 8-doses of an Australian TGA approved SARS-CoV-2 vaccine (including mRNA \[Pfizer or Moderna\], ChAdOx1 \[Oxford/Astra Zeneca\] or protein \[Novavax\])
* Fit the criteria to be included in one of the following 3 populations: Infected with HIV; Current recipient of a solid organ transplant including: kidney, pancreas, liver, malignancy episodes of severe rejection requiring T- or B-cell depleting agents in the prior 3 months; Undergoing chemotherapy, immunotherapy and/or targeted therapy, or completed in the last 2 years for: chronic lymphocytic leukemia, multiple myeloma or non-Hodgkin lymphoma.

Exclusion Criteria:

* Are contraindicated to receive a COVID-19 booster vaccination, e.g. history of anaphylaxis to a vaccine component or myocarditis attributed to previous receipt of an mRNA vaccine.
* Has had less than 3 or more than 8 doses of COVID-19 vaccine
* Is on another clinical trial investigating alternate COVID-19 vaccination schedules or investigational drugs to prevent or treat COVID-19
* Life expectancy \< 12 months, or enrolment deemed not in the best interest of the patient
* Unable to provide informed consent
* Receipt of SARS-CoV-2 specific monoclonal antibodies in the 3 months prior to receiving the first dose of study vaccine
* Acute respiratory tract infection and/or temperature \> 38 degrees centigrade on day of receiving first dose of study vaccine
* History of autologous stem cell transplant in the prior 6 months or history of ever having an allogeneic stem cell transplant or CAR T-cell therapy
* Have not received another licensed vaccine in the 7 days before or 7 days after the day of receiving the COVID-19 study vaccine (NOTE: Participants can receive another licensed vaccine on the same day as the COVID-19 vaccine)
