Clinical Evidence

Key evidence and references: MOXIe Study reporting effects on mFARS (Ann Neurol. 2021;89(2):212-225) and the Skyclarys Prescribing Information (Reata Pharmaceuticals, January 2024). Policy aligns coverage to FDA labeling and MOXIe trial outcomes on mFARS, and uses the prescribing information for dosing and safety parameters.

Background

Background: Omaveloxolone (Skyclarys) is an Nrf2 pathway activator indicated for Friedreich's ataxia in adults and adolescents 16 years and older. The policy aligns to FDA labeling and evidence from the MOXIe trial and specifies requirements including documentation of a GAA triplet-repeat expansion in the frataxin (FXN) gene, prescribing by or in consultation with a neurologist, and baseline assessments of left ventricular ejection fraction and modified Friedreich Ataxia Rating Scale (mFARS).

Definitions: The mFARS (modified Friedreich Ataxia Rating Scale) is a disease-specific, exam-based neurological rating scale (maximum 93 points) assessing bulbar function, upper and lower limb coordination, and upright stability, where higher scores indicate greater disability.

FXN refers to the frataxin gene; genetic testing for a GAA triplet-repeat expansion in FXN is required to document Friedreich's ataxia.

FA (Friedreich's ataxia) is a progressive, life-shortening ataxia with cardinal symptoms including progressive limb ataxia, areflexia, extensor plantar responses, and dysarthria, and may involve cardiomyopathy and metabolic disturbances.

Revision History

2023-02-28policy_effective

Policy effective date established aligning coverage to FDA labeling and MOXIe evidence; initial approval criteria include diagnosis of FA, genetic testing showing GAA triplet‑repeat expansion in FXN, neurologist involvement, age ≥16, baseline mFARS and baseline LVEF ≥40%, and dosing limit of 150 mg/day (max 3 capsules).

04.11.23material_revision

Revised to align with FDA labeling: dosing updated to 150 mg/day (150 mg QD), added requirement for baseline left ventricular ejection fraction ≥40% and references to cardiac history per PI; policy updated per FDA labeling and MOXIe trial evidence. (Marked material change.)

Prior Authorization

Renewal approval duration

Approval duration: 12 months. Renewal requires documentation showing improvement or stabilization in Friedreich's ataxia (FA) symptoms or in the mFARS score; continued therapy approvals are granted for 12 months.

Billing Rule

Dose limits enforceable

Enforce dose limits: maximum 150 mg per day and maximum 3 capsules per day. Any request for a dose increase must adhere to these limits.

Prior Authorization

Continued therapy evidence

For renewal, provide documentation showing improvement or stabilization in FA symptoms or mFARS score to justify continued coverage. Renewal approvals are granted for 12 months.

Removed requirement for maximal exercise testing on a recumbent stationary bicycle as it is not required per the Prescribing Information. (Marked material change.)

11.08.23material_revision

Multiple clarifications and removals: added explicit genetic testing requirement showing a GAA triplet‑repeat expansion in the FXN gene; removed the prior mFARS 20–80 band; removed exclusions for history of clinically significant left‑sided heart disease/cardiac disease and for pes cavus; removed requirement for ability to swallow capsules; changed continued therapy language from 'improvement' to 'improvement or stabilization' and extended approval duration from 6 months to 12 months.
