Eligibility
Key inclusion criteria
A subject must meet all of the following inclusion criteria at the Screening and Baseline
Visit (unless otherwise specified) to be eligible for inclusion in the SPIMD-301 trial:

1. Willing and able to provide a signed informed consent form (ICF) prior to
participation in any trial-related procedures.

2. Agrees and is able to adhere to the trial requirements for the length of the trial,
including administration of assigned treatment.

3. Is =18 years and = 70 years of age at the time of screening.

4. Diagnosed with nPMD with a predominant clinical manifestation of myopathy, which must
include progressive external ophthalmoplegia (PEO) and exercise intolerance and/or
skeletal muscle weakness, with genetic confirmation of either:

1. Nuclear DNA mutation of the mitochondrial replisome (replisome-related
mutations), which include the following genes:

- POLG 1/2

- TWINKLE (C10ORF2)

- TYMP

- DGUOK

- TK2

- RRM2B

- RNASEH1

- SSBP

- MGME1

- DNA2

- ANT1 (SLC25A4)

- SUCLG1

- SUCLA2

- MPV17 or

2. Other pathogenic mutations specific to nuclear DNA.

5. Women of childbearing potential must agree to use one of the following methods of
birth control from the date they sign the ICF until 28 days after the last dose of
IMP:

1. Abstinence, when it is in line with the preferred and usual lifestyle of the
subject. Subject agrees to use a highly effective method of contraception should
they become sexually active.

2. Relationships with male partners who have been surgically sterilized by vasectomy
(the vasectomy procedure must have been conducted at least 60 days prior to the
Screening Visit).

3. Barrier method (e.g., condom or occlusive cap) with spermicidal
foam/gel/film/cream AND either hormonal contraception (oral, implanted, or
injectable) or an intrauterine device or system.

Note: Non-childbearing potential is defined as surgical sterilization (e.g., bilateral
oophorectomy, hysterectomy, or tubal ligation) or postmenopausal (defined as permanent
cessation of menstruation for at least 12 consecutive months prior to the Screening
Visit).

6. Male subjects with female partners of childbearing potential must be willing to use a
highly effective method of contraception from the date they sign the ICF until 28 days
after the last dose of IMP.
Minimum age
18 Years
Maximum age
70 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Is unable to perform the 6MWT, 3TUG, or 5XSST functional tests. The use of a gait
assist device is allowed; however, use should remain consistent for the entire
duration of the trial.

2. Female subjects who are pregnant, planning to become pregnant, or
breastfeeding/lactating.

3. Walks < 150 meters or > 450 meters during the 6MWT (Screening Visit only).

4. The estimated glomerular filtration rate (eGFR) is < 30 mL/min/1.73 m2, using the
Modification of Diet in Renal Disease (MDRD) Study equation (Screening Visit only).

5. Has undergone an in-patient hospitalization within 30 days prior to screening or has a
planned hospitalization or a surgical procedure during the trial, unless, in the
opinion of the Investigator, it is concluded that it will not impact the outcome
measurements of the trial.

6. Has clinically significant respiratory disease and/or cardiac disease that would
interfere with trial assessments, in the opinion of the Investigator.

7. Has had any prior interventional cardiac procedure (e.g., cardiac catheterization,
angioplasty/percutaneous coronary intervention, balloon valvuloplasty, etc.) within 3
months prior to screening.

8. Has history of or current severe neurologic impairment, severe epilepsy, severe
ataxia, or severe neuropathy that may interfere with their ability to complete all
trial requirements, in the opinion of the Investigator.

9. Active malignancy or any other cancer from which the subject has been disease-free for
< 2 years. Localized squamous or non-invasive basal cell skin carcinomas are allowed,
if appropriately treated prior to screening.

10. Has had a solid organ transplant.

11. Has been previously diagnosed with human immunodeficiency virus (HIV), hepatitis B, or
hepatitis C infection.

12. Has a history of a systemic eosinophilic illness and/or an eosinophil count >1,000
cells x106/L at the Screening Visit.

13. Is currently participating or has participated in an interventional clinical trial
(i.e., investigational product or device, stem cell therapy, gene therapy) within 30
days prior to current trial; or is currently enrolled in a non-interventional clinical
trial that, in the opinion of the Investigator, may be potentially confounding to the
results of the current trial (e.g., exercise therapy trial).

14. Has received elamipretide (MTP-131) within the past one year of the Screening Visit.

15. Has a history of active substance abuse during the year prior, in the opinion of the
Investigator.
