Mitochondrial Disease Therapeutic Pipeline
All new treatments or therapeutics proceed through a defined development path. This path begins with preclinical development and progresses through clinical trials all the way to FDA-approval before ending in patients’ hands.
Several treatments for mitochondrial diseases are already making their way along this path. Soon mito patients and their families will be able to see the treatment approaches being developed, where they are in the development pipeline, and what mitochondrial diseases they target.
Conditions in the Pipeline
- Barth Syndrome
- Inherited Mitochondrial Disorders
- KSS-CPEO
- Leigh Syndrome
- LHON
- MELAS
- MERRF
- Mitochondrial Myopathies
- MIDD
- Pearson Syndrome
- PDCD
- Seizures
- TK2 Deficiency

Pre-Clinical Development
Non-human lab testing

Phase I
Human safety trial

Phase II
Preliminary human efficacy trial

Phase III
Definitive human safety & efficacy trial

Regulatory Approval
New drug approved & available to patients
Phase I/II tests the safety, side effects, and best dose of a new treatment.
Phase II/III tests how well a new treatment works and compares the new treatment with a standard treatment.
