Mallinckrodt plc (NYSE:MNK) announced that it has enrolled the first patient in its phase IIB study, PENNANT. The study is designed to assess the efficacy and safety of H.P. Acthar Gel for the treatment of amyotrophic lateral sclerosis (ALS).

The study will enroll patients between ages 18 to 75 with ALS and symptom onset (defined as first muscle weakness or dysarthria) ≤ two years prior to the screening visit.

The patients (n=195) will be randomized on a 2:1 basis to receive subcutaneous (SC) Acthar Gel 0.2 mL (16 units) daily or SC matching placebo 0.2 mL daily for 36 weeks.

The efficacy of Acthar gel will be evaluated using standard measures of functional decline, including change from baseline in the ALS Functional Rating Scale-Revised, assessed after 36 weeks of therapy.
