Horizon slumps after phase 3 Friedreich's ataxia trial flops

FierceBiotech. by Nick Paul Taylor | Dec 8, 2016 9:40am. Horizon Pharma’s Actimmune has missed the primary endpoint in a phase 3 trial, sparking a 20% drop in its stock price. The study set out to show that interferon gamma-1b could improve outcomes in patients with the rare neurodegenerative movement disorder Friedreich's ataxia, but the drug failed to move the needle.

Horizon Pharma’s Phase 3 study assessing actimmune for the treatment of Friedreich’s ataxia did not meet its primary endpoint of displaying significant change in the modified Friedreich's Ataxia Rating Scale (FARS‐mNeuro) during a 26-week time period.


Globe Newswire. 8th December 2016. Today announced that the Phase 3 trial, STEADFAST (Safety, Tolerability and Efficacy of ACTIMMUNE Dose Escalation in Friedreich’s Ataxia study), evaluating ACTIMMUNE® (interferon gamma-1b) for the treatment of Friedreich’s ataxia (FA) did not meet its primary endpoint of a statistically significant change from baseline in the modified Friedreich’s Ataxia Rating Scale (FARS‐mNeuro) at 26 weeks versus treatment with placebo. FARS‐mNeuro is an exam-based rating scale that measures disease progression based on functional parameters such as speech, ability to swallow, upper and lower limb coordination, gait and posture. In addition, the secondary endpoints did not meet statistical significance. No new safety findings were identified on initial review of data other than those already noted in the ACTIMMUNE prescribing information for approved indications.
