Purpose

The goal of this clinical trial is to evaluate the efficacy, safety and pharmacokinetics of elamipretide in subjects with dry age-related macular degeneration (AMD). The main questions it aims to answer are: what is the rate of change in the macular area of photoreceptor loss in subjects who receive a daily dose of elamipretide compared with those who receive a look-alike substance that contains no active drug, and what is the safety and tolerability of elamipretide daily subcutaneous injections. Participants will receive either once daily subcutaneous doses of 40mg elamipretide or placebo and the two treatment groups will be compared.

Inclusion Criteria

A subject must meet all the inclusion criteria at the Screening and Baseline Visit (unless otherwise specified) to be eligible for inclusion in the trial. 1. Adults ≥ 55 years of age with at least 1 eye with dry AMD with photoreceptor loss, as determined at the Screening Visit by the presence of extrafoveal geographic atrophy (GA), as determined by the Reading Center primarily by fundus autofluorescence (FAF). For this trial, extrafoveal GA is defined as: 1. well-demarcated area(s) of GA 2. All GA lesions must be at least 150 μm from foveal center Note: The fellow eye may have any of the following: no AMD, AMD without GA, AMD with GA, CNV AMD, or foveal GA (ongoing treatment with anti-angiogenic therapies and/or complement inhibitor therapies in the fellow eye is allowable) Ocular conditions - Study Eye: 2. GA in the study eye at the Screening Visit may be multi-focal, but the cumulative GA lesion and size (by FAF, as determined by the Reading Center) must: 1. be ≥ 0.50 mm2 and ≤ 10.16 mm2 AND 2. reside completely within the FAF 30- or 35-degree image 3. BCVA by Early Treatment Diabetic Retinopathy Study (ETDRS) score of ≥ 55 letters in the study eye 4. LL BCVA by ETDRS score of ≥ 10 letters in the study eye 5. LLD (defined as the difference between BCVA and LL BCVA) of > 5 letters in the study eye 6. Sufficiently clear ocular media, adequate pupillary dilation, fixation to permit quality fundus imaging, and ability to cooperate sufficiently for adequate ophthalmic visual function testing and anatomic assessment in the study eye Systemic and General Criteria: 7. Able to administer IMP or have an appropriate designee who can administer the IMP (i.e., a capable family member or a caregiver) 8. Able to provide informed consent and willing to comply with all site visits, examinations, daily IMP administrations and dosing diary entries, and other conditions of the trial protocol 9. Women of childbearing potential must agree to use 1 of the following methods of contraception 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). 10. Male subjects with female partners of childbearing potential must be willing to use a highly effective method of contraception (e.g., abstinence, dual method of contraception) from the date they sign the ICF until 28 days after the last dose of IMP

Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description
Trial personnel and subjects will be masked to treatment until the database is locked at the end of the trial, unless noted below. The Investigator will contact the Sponsor Medical Monitor prior to unmasking any subject's treatment sequence unless in the instance of a medical emergency. In case of an immediate medical emergency, or if directed by the Sponsor, and only if the information is required by the Investigator to manage a subject's AE, a subject's treatment assignment may be unmasked prematurely using the computerized system. The Sponsor must be notified as soon as possible regarding the reason for unmasking.

Detailed Description

The ReNEW (SPIAM-301) trial is a phase 3, randomized, double-masked, parallel-group, placebo-controlled clinical trial to evaluate the efficacy, safety, and pharmacokinetics of a once daily subcutaneous (SC) injection of elamipretide in subjects who have dry AMD. Subjects will be randomized (2:1) to once daily SC doses of 40 mg elamipretide, or placebo for 96 weeks of treatment by a central randomization and stratified by SD-OCT device type (Heidelberg SPECTRALIS®, ZEISS CIRRUS®) and baseline macular area of photoreceptor loss, defined as an ellipsoid zone-retinal pigment epithelium (EZ-RPE) thickness of 0μm assessed by SD-OCT and ellipsoid zone (EZ) mapping (High Strata ≥ 5.1mm2, Low Strata <5.1mm2). Primary Objective - Evaluate the efficacy of once daily subcutaneous (SC) injections of elamipretide in subjects who have dry age-related macular degeneration (AMD) Secondary Objectives - Evaluate the safety and tolerability of once daily SC injections of elamipretide - Evaluate the Pharmacokinetic (PK) profile of elamipretide and its metabolites

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health).
