Frequently Asked Questions About MMPOWER-3
What will MMPOWER-3 study?
- MMPOWER-3 is a phase 3, randomized, double-blind, parallel-group, placebo-controlled trial to evaluate the efficacy and safety of daily subcutaneous (under the skin) injections of elamipretide in patients with PMM followed by an open-label treatment extension.
- The trial will primarily assess the change in distance walked during the six-minute walk test (6MWT) and patient-reported fatigue using a PMM-specific questionnaire, the Primary Mitochondrial Myopathy Symptom Assessment (PMMSA). Secondarily, the trial will evaluate changes in fatigue during activities using the PMMSA, quality of life, impact on the patient’s most bothersome symptom on the PMMSA, and safety and tolerability of treatment with elamipretide.
What is the drug being studied, and how does it work?
- In MMPOWER-3, Stealth is evaluating elamipretide delivered by subcutaneous (under the skin) injection. Elamipretide is an investigational drug that associates with cardiolipin, a key structural component of the inner mitochondrial membrane, and has shown to improve mitochondrial function in preclinical and early clinical studies.
How will investigators select patients to participate in the MMPOWER-3 trial?
- Patients that have a genetic confirmation of mitochondrial disease are potentially eligible for participation in MMPOWER-3. The clinical trial investigator will identify potential patients.
How long does MMPOWER-3 last?
- Subjects enrolled in the trial will receive daily injections of elamipretide or placebo for six months. At the end of the six-month period, subjects may elect to participate in the open-label treatment extension and will receive elamipretide for the duration of the trial.

STEALTH BIOTHERAPEUTICS SHARES PROMISING DATA FROM MITOCHONDRIAL MYOPATHY TRIAL
Recently, at the 2017 UMDF Mitochondrial Medicine Symposium, Stealth BioTherapeutics shared very encouraging results from its second clinical trial for primary mitochondrial myopathy, the MMPOWER-2 study. Stealth is a Boston-based biopharmaceutical company developing therapeutics to treat mitochondrial dysfunction; its lead drug under investigation is elamipretide (previously known as Bendavia). Primary mitochondrial myopathy (PMM) is a genetically-acquired mitochondrial disease characterized by signs and symptoms of myopathy (debilitating muscle weakness, easy fatigability, exercise intolerance and pain). The Phase 2 MMPOWER-2 trial was conducted to evaluate safety, tolerability and efficacy of treatment using elamipretide in 30 adult (ages 16-65) patients with PMM. An overall assessment of the top-line MMPOWER-2 results showed benefit across multiple endpoints and is supportive of continuation toward a Phase 3 study in this patient population.
Patients enrolled in MMPOWER-2 previously participated in Stealth’s MMPOWER trial, designed to assess dosing, which demonstrated a dose-dependent improvement in distance walked in the 6-Minute walk test (6MWT) after 5 days of once daily intravenous administration of elamipretide or placebo. In MMPOWER-2, patients were randomized to once daily subcutaneous administration of elamipretide or placebo for a longer period of time (four weeks), and then, after a washout period, received the opposite treatment during a second four-week dosing period. Patients, their doctors and investigators at Stealth were unaware of which group patients belonged to during the trial and the subsequent assessments.
This type of study design, known as a randomized, double-blind, placebo-controlled crossover study, is considered a “gold standard” in clinical trials evaluating investigational drugs. Randomized controlled trials can be challenging in rare and orphan diseases because there simply are not as many patients available to participate, and there tend to be as many differences as there are similarities between patients who may have the same diagnosis (also known as heterogeneity).
Multiple endpoints, or outcomes, were considered and evaluated during the MMPOWER-2 trial in addition to the 6MWT, including the Neuro-QoL (Quality of Life in Neurological Disorders) measurement system, and a new patient-reported outcome tool, the Primary Mitochondrial Myopathy Symptom Assessment (PMMSA), developed by Stealth specifically for this patient population. Other tools and measures for safety, tolerability and functional assessment were also applied.

Adult Mitochondrial Disorders Clinical Trials
Reata Pharmaceuticals (RTA 408, omavaloxolone)– In preclinical studies RTA 408 was shown to target inflammatory, metabolic, and mitochondrial pathways by inducing Nrf2 and suppressing NF-kB. Unlike other drugs in development for the treatment of mitochondrial disease, RTA 408 directly affects mitochondrial function and energy production in muscle cells. In 2015, Reata launched a Phase 2 clinical trial (the MOTOR study) to evaluate the efficacy, safety, and pharmacodynamics of RTA 408 in the treatment of adult patients with mitochondrial myopathy. Exercise capacity is utilized in MOTOR as the primary efficacy endpoint through measuring change in peak work during maximal exercise testing. Currently patients are being enrolled across 9 sites in the dose-ranging portion of this 2-part study. Initial results on the dose-ranging portion (part 1) are expected in early 2018.

Stealth BioTheapeutics (MTP-131, elamipretide)- MTP-131 is a small molecule peptide designed to penetrate the cellular and outer mitochondrial membrane and target cardiolipin, which is found exclusively in the inner mitochondrial membrane. MTP-131 has been shown to positively impact dysfunctional mitochondria in nonclinical studies, with no effect in healthy mitochondria. In June 2016 Stealth reported positive preliminary findings on topline data from a Phase 1/2 study to evaluate safety, tolerability and efficacy of MTP-131 to treat mitochondrial myopathy in adult patients with genetically-confirmed mitochondrial disease (MMPOWER study). A follow-on Phase 2 trial (MMPOWER2) focused on subcutaneous efficacy launched returned positive data in 2017. In anticipation of a Phase 3 trial in 2018, Stealth has launched a 1-year observational study (RePOWER) from which Phase 3 participants will be recruited.
