What this research studies

You would join a basket clinical trial that combines people with MELAS and LHON‑Plus so researchers can study both groups together. The trial targets a shared molecular problem called Complex I deficiency that lowers mitochondrial ATP production and causes chronic energy shortage in cells. The project moves from early development into clinical testing to look at safety, feasibility, and whether symptoms like stroke‑like episodes, muscle weakness, or vision loss improve or stabilize. Because these conditions are ultra‑rare, the study works through the Rare Diseases Clinical Research Network to recruit patients and make the trial possible.

Who could benefit from this research

Good fit: People with a confirmed genetic diagnosis of MELAS or LHON‑Plus due to mitochondrial Complex I defects who are willing and able to attend visits at participating clinical sites.

Not a fit: People with other types of mitochondrial disease not caused by Complex I defects, those without a confirmed genetic diagnosis, or those unable to travel to trial sites are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, the treatment could raise cellular energy production and reduce major symptoms such as stroke‑like episodes, muscle weakness, or vision loss.

How similar studies have performed: Some mitochondrial‑targeting drugs have shown mixed results (for example, idebenone in LHON), so this approach builds on limited prior successes but remains experimental.
