MNGIE (Mitochondrial Neurogastrointestinal Encephalomyopathy) AHSCT (Allogeneic Hematopoietic Stem Cell Transplant) Safety Study

The purpose of this study is to find out if a stem cell transplant is safe for patients with
a very rare disease. The stem cell transplant is called AHSCT (for "allogeneic hematopoetic
stem cell transplantation"). The rare disease is called MNGIE (for "Mitochondrial
NeuroGastroIntestinal Encephalomyopathy"). Patients with MNGIE will be transplanted with
stem cells from an individual who is human leukocyte antigen (HLA) 10/10 matched. The
purpose of the transplant is the production of thymidine phosphorylase.

Patients who have been identified as having MNGIE by genetic testing and/or reduced
thymidine phosphorylase levels will be considered for this study. The study team physician
will evaluate the condition of the patient and determine if they are eligible. An HLA
matched donor is necessary for transplantation. If a suitable donor is found the transplant
process can proceed. The patient receives immunosuppressive therapy ( 1 week in the
hospital) with subsequent IV transfer of stem cells from the donor. The patient remains in
the hospital for approximately 1 month to monitor the transplant. The patient is required to
attend research visits at days 0, 100, 6m, 18m and 24 m.
