MMPOWER-3 — structured trial abstract
MMPOWER-3 — SS-31 (elamipretide) in mitochondrial disease: randomised, double-blind, placebo-controlled
§1Structured abstract
§1.1Objective
To evaluate SS-31 (elamipretide) in primary mitochondrial myopathy and bioenergetic disorders, against the comparator specified in §2, with the primary endpoint stated below.
§1.2Design
- Design
- Randomised, double-blind, placebo-controlled, parallel-group
- Masking
- Double-blind (participant, investigator and sponsor)
- Phase
- Phase 3
- Randomised participants
- 218
- Duration of the primary analysis period
- 24 weeks
- Sponsor class
- Manufacturer-sponsored
- Registry identifier
- not reproduced — see the note in §1.5
§1.3Primary endpoint
Change in six-minute walk distance and in the primary mitochondrial myopathy symptom assessment total fatigue score at week 24
§1.4Principal result
Neither primary endpoint was met. The Institute records MMPOWER-3 as a negative phase 3 result and treats it as informative evidence rather than as an absence of evidence.
§1.5Provenance of this abstract
Table 1. Field-by-field provenance. The Institute records which fields are extracted from a source and which are its own reconstruction, so that a reader can tell the two apart without leaving the page.
| Field | Provenance | Note |
|---|---|---|
| Design, phase, duration, primary endpoint | Extracted | Reproduced from the published report or the registry record. |
| Randomised participants | Extracted | Reproduced as published. |
| Principal result | Extracted | Reproduced as published, with the confidence interval where the Institute holds it. |
| Centres, countries and baseline characteristics | Reconstructed | Derived by the Institute from the design class and the randomised total. Presented in §2 as an illustrative operational profile and marked as such. These figures are not published characteristics of this trial. |
| Certainty assessment | Institute judgement | The Institute’s own domain-by-domain assessment, with reasoning recorded against each domain in §4. |
| Registry identifier | Not held | The Institute does not reproduce a registry identifier it has not verified and never constructs one. Documents are referenced by the Institute’s own identifier. |
