The FALCON study is divided into three parts
Screening
Many tests to see if you meet the criteria to join
Treatment
Participants will be randomly assigned, like picking straws, to receive either the study drug or a placebo, which has no active ingredients.
Neither the participants nor the study team will know who is receiving the study drug or placebo. Participants will not be able to change which one they are assigned.
Safety Follow-Up Visit
For every 5 study participants, 3 will receive napazimone (KL1333)
and 2 will receive the placebo, which has no active ingredients

About clinical studies
- Clinical research studies, which are also called clinical trials, are conducted by researchers who are looking for better ways to prevent, diagnose, or treat a health condition
- The data collected from clinical studies is shared with regulatory organizations who decide if a new medicine is safe, works as intended, and can be approved
- Studies follow specific laws to protect the rights, safety, well-being and privacy of participants

Why join?
- Joining the FALCON study will help researchers learn if napazimone (KL1333) works as intended to help improve symptoms in people living with primary mitochondrial disease, also known as Mito.
- Joining a clinical trial is an important, personal decision. Talk to your doctor to understand if it is the right decision for you.
What else should I consider?
There is some risk involved in any clinical study. Possible risks for participants include:
- May experience a side effect or health problem
- May get the placebo
- The study drug may not work or may not work better than the standard treatment
- May require more time and have more doctor’s visits than their regular healthcare
