More patients with POMS have no new or newly enlarged (N or NE) T2 hyperintense lesions with dimethyl fumarate (DMF) treatment compared with interferon β-1a (IFNβ-1a) treatment, and the annual recurrence rate is lower than DMF, according to a study published online on September 28 at JAMA Open Network.

Patrick Vermeersch, MD, PhD, of the Lille University Hospital Center in France, and colleagues conducted an open-label, randomized, active-controlled clinical trial in patients with PMS between the ages of 10 and

The researchers found that among the 103 participants who completed the study, the proportion of patients without N or NE T2 hyperintense lesions at week 96 was 16.1 percent and 4.9 percent for DMF and IFNβ-1a, respectively; in a sensitivity analysis among the treatment-planned population, the proportions were 12.8 and 2.8 percent, respectively. The estimated proportion of patients who did not relapse was 66.2 and 52.3 percent, respectively, for DMF and IFNβ-1a at week 96. Adjusted annual recurrence rates were 0.24 and 0.53 for DMF and IFNβ-1a, respectively, at week 96; the rate ratio was 0.46 for DMF versus IFNβ-1a.

“The CONNECT randomized clinical trial showed that DMF resulted in significant improvements in radiographic and clinical outcomes in patients with POMS, with a positive benefit-risk ratio,” the authors wrote.

Several authors have disclosed financial ties to biopharmaceutical companies, including Biogen, which manufactures dimethyl fumarate and funded the lawsuit.
