Clinical Trial Summary

Primary Mitochondrial diseases are a clinically and genetically heterogeneous group of disorders caused by mutations in genes encoded by nuclear Deoxyribonucleic Acid (DNA) or by mutations and/or deletions in the mitochondrial DNA (mtDNA). While some mitochondrial disorders only affect a single organ (e.g., the eye in Leber hereditary optic neuropathy [LHON]), many involve multiple organs. Mitochondrial disorders may present at any age and a frequent feature is the increasing number of organs involved in the course of the disease. Minovia Therapeutics Ltd. ("Minovia") is a biotech company developing novel therapeutics based on its mitochondrial augmentation technology (MAT). MNV-201 is a cell therapy produced by MAT that consists of the participant's autologous CD34+ hematopoietic stem and progenitor cells (HSPCs) enriched with allogeneic placental-derived mitochondria, manufactured in Minovia's GMP facility.

Intervention

Biological:
• MNV-201
Autologous CD34+ cells are isolated from the participant's peripheral blood after mobilization by leukapheresis. Allogeneic mitochondria are isolated under aseptic conditions from healthy donor placenta, cryopreserved and qualified before use.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Occurrence of treatment-related adverse events	Occurrence of treatment-related adverse events as assessed by CTCAE v5.0 following MNV-201 infusion.	12 months post treatment.
Secondary	Stabilization or improvement in Quality of Life (QoL) questionnaire IPMDS (International Pediatric Mitochondrial Disease Scale) scores	The score is expressed as the percentage of items which were feasible to perform. The lower the score, the better is the child performance.	12 months post treatment
Secondary	Reduction in frequency and lengths of hospitalization during the 12 months after MAT compared to the 12 months period before MAT		12 months post treatment
Secondary	Changes in anemia during a follow up period of 12 months post treatment.	Changes since baseline in anemia during a follow up period of 12 months post treatment measured by Complete Blood Count.	12 months post treatment.
Secondary	Changes in thrombocytopenia during a follow up period of 12 months post treatment	Changes since baseline in thrombocytopenia during a follow up period of 12 months post treatment measured by Complete Blood Count.	12 months post treatment
Secondary	Changes in leukopenia during a follow up period of 12 months post treatment	Changes since baseline in leukopenia during a follow up period of 12 months post treatment measured by Complete Blood Count.	12 months post treatment
Secondary	Changes in frequency of blood transfusions during a follow up period of 12 months post treatment.	Changes in frequency of blood transfusion will be assessed based on the number of blood transfusions received by the participant since baseline compared to the number of blood transfusions the participant received during the 6 months period pre screening.	12 months post treatment.
