Understanding brain chemistry in patients with primary mitochondrial disease
This study is trying to see if measuring certain brain chemicals can help doctors better understand and treat people with primary mitochondrial disease.
-
Evaluating KL1333 for treating primary mitochondrial disease
This study is testing if a new drug called KL1333 can help adults with primary mitochondrial disease feel less tired and improve their physical abilities over 48 weeks.
-
Measuring disease progression in mitochondrial myopathy
This study is trying to find better ways to track how primary mitochondrial myopathy changes over time in patients so that future treatments can be developed more effectively.
Quick answers
How many Primary Mitochondrial Disease clinical trials are recruiting right now?
3, as of November 12, 2026. We update this list each time we refresh our data from ClinicalTrials.gov.
Where are these trials running?
In 11 countries. The most sites are in United States (3 trials), Australia (1 trial), Belgium (1 trial), Czechia (1 trial), Denmark (1 trial). Each study page lists its sites and which ones are recruiting.
What phases are they in?
Phase 2: 1. Trials with no phase listed are usually device, behavioural or observational studies.
How do I join one?
Open a study, check the "Is this trial a fit for you?" section, then contact the study team listed on the page. They will ask a few screening questions. Asking is free and does not commit you to anything. Talk it over with your doctor first.
