PABLO: This phase II trial is trying to understand whether it is more or less effective to use parent donors for bone marrow transplants in children, using a particular processing method of the donor blood cells compared to those receiving a standard bone marrow transplant from another donorTCR a+ß+/CD19+ cell depleted haploidentical donor stem cell transplantation for paediatric patients

Clinical summary

Summary

In this trial, patients will be assigned to one of two treating arms, according to whether a matched donor is available. In Arm 1, patients who have no fully matched brothers or sisters, volunteer donors or umbilical cord blood units available will receive a TCR a+ß+/CD19+ cell depleted graft from a parent donor. Control patients (Arm 2) will receive a standard bone marrow transplant from another donor (e.g., volunteer donor) as per institutional practice. All patients enrolled in this trial will have regular clinical assessments for two years post-transplant to evaluate the efficacy of their treatment. Further information, such as quality of life and carer burden, will be collected for up to 5 years post-transplant.

Conditions

This trial is treating people with haematological (blood) cancer
