The risk of malignancy is not increased in patients with multiple sclerosis treated with subcutaneous interferon beta-1a

Sandberg-Wollheim et al. Mult Scler. 2011 Apr;17(4):431-40.

Analysis of pooled safety data from 12 key clinical trials did not show an increased incidence of malignancy per 1000 patient-years with sc IFN beta-1a (4.0; 95% confidence interval (CI): 2.9-5.5) compared with placebo (6.4; 95% CI: 3.3-11.2).

Conclusion: Safety data from both clinical trial and post-marketing settings suggest that treatment with sc IFN beta-1a does not increase the risk of malignancy in patients with MS.

“Reassuring!”
