Omaveloxolone is the most effective pharmacological intervention for Friedreich's ataxia, showing biological improvements without clear clinical benefit.

This systematic review of 90 studies found that omaveloxolone was the most effective pharmacological intervention for Friedreich's ataxia. However, pharmacological studies generally showed biological improvements without clear clinical benefit, while nonpharmacological therapies yielded more consistent patient-relevant gains.
