COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
The investigational product (IP) is ‘multi-virus-specific T cells TI1’, and consists of T cells targeting cytomegalovirus (CMV), Epstein–Barr virus (EBV), BK polyomavirus (BKV) and adenovirus (AdV). In this trial, IP will be generated for each participant from the peripheral blood of the haploidentical haematopoietic stem cell transplant (haplo-HSCT) donor. The safety of the IP in a preventative (prophylactic) setting will be tested in 20 paediatric TCRaß+/CD19+-depleted haplo-HSCT recipients. Participants will be recruited from Queensland Children’s Hospital, The Royal Children’s Hospital Melbourne, The Children’s Hospital at Westmead, and Sydney Children’s Hospital.

Patients and donors will be recruited prior to donor stem cell mobilisation, and the IP will be generated from the peripheral blood of the donor, with manufacturing conducted at Q-Gen Cell Therapeutics.

IP infusions will commence following engraftment, once the criteria for infusion commencement are met, and each infusion will be given at the recruiting hospital. Participants will receive up to six fortnightly intravenous infusions (depending on the number of cells grown), at a dose of 2 × 107 cells/m2, suspended in 20 mL clinical grade normal saline. 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.

Outcomes
Primary outcome [1] 322308 0
The incidence of adverse events, and clinically significant changes in laboratory tests and vital signs observations.
Timepoint [1] 322308 0
Adverse events will be collected at each visit, commencing at the first infusion visit, and finishing approximately 10 weeks following the final infusion. Safety blood tests (FBC, ELFT, and viral load) will be collected at the first infusion visit until the final follow-up visit, approximately 7.5 months following the final infusion. Vital signs observations will be done during and immediately following each T cell infusion.
Secondary outcome [1] 378029 0
The change in the proportion of functional virus-specific T cells, from prior to the first infusion to the first follow-up visit and at final follow-up.
Timepoint [1] 378029 0
Blood will be collected at each study visit (all infusions and follow-up visits) to allow the examination of peripheral blood mononuclear cells. These cells will be analysed to assess their phenotype and function over the course of the trial to determine any changes.

Eligibility
Key inclusion criteria
1. Aged between 3 months and 18 years
2. Patient has a condition for which HSCT is indicated
3. Transplant physician determines that optimal donor is haploidentical*
4. Haplo-HSCT donor is aged 18 or above
5. Haplo-HSCT donor is available and willing to donate blood for therapy manufacture

* This decision is usually based upon lack of HLA matched sibling or fully matched unrelated donor, but may be influenced by other factors such as donor availability or urgency of HSCT.

Summary
Brief summary
Patients who receive a type of transplant called a haploidentical haematopoietic stem cell transplant (haplo-HSCT), which is not an ideal tissue match for the patient, are at a high risk of developing a viral infection. This is because the immune cells that can fight viruses (called T cells) are removed from the transplant before it is given.

In this trial, we will test a new preventative T cell therapy for four common viruses in patients who have received a haplo-HSCT. The therapy will be grown from the blood of the transplant donor and given to patients after their transplant.

One aim of this trial is to see if this T cell therapy is safe for transplant patients. In addition, we would like to see if the T cells that we grow in the laboratory from the transplant donors can help to restore the recipients’ immune systems. This may help prevent infectious complications from developing.
