The investigators want to study if lower doses of chemotherapy will help babies with SCID to
achieve good immunity with less short and long-term risks of complications after
transplantation. This trial identifies babies with types of immune deficiencies that are most
likely to succeed with this approach and offers them transplant early in life before they get
severe infections or later if their infections are under control. It includes only patients
receiving unrelated or mismatched related donor transplants.

The study will test if patients receiving transplant using either a low dose busulfan or a
medium dose busulfan will have immune recovery of both T and B cells, measured by the ability
to respond to immunizations after transplant. The exact regimen depends on the subtype of
SCID the patient has. Donors used for transplant must be unrelated or half-matched related
(haploidentical) donors, and peripheral blood stem cells must be used. To minimize the chance
of graft-versus-host disease (GVHD), the stem cells will have most, but not all, of the T
cells removed, using a newer, experimental approach of a well-established technology. Once
the stem cell transplant is completed, patients will be followed for 3 years. Approximately
9-18 months after the transplant, vaccinations will be administered, and a blood test
measuring whether your child's body has responded to the vaccine will be collected.

This is a Phase III, randomised, double-blind, placebo-controlled, multicentre, international
study assessing the efficacy and safety of durvalumab (MEDI4736) and domvanalimab (AB154)
compared with durvalumab plus placebo in adults with locally advanced (Stage III),
unresectable NSCLC whose disease has not progressed following definitive platinum-based cCRT.
