The study, “Acute acalculous cholecystitis — A new safety risk for patients with MS treated with alemtuzumab,” was published in the journal Neurology.

AAC is a disease affecting the gallbladder characterized by inflammation, which may lead to tissue death.

Initial product labeling for Sanofi Genzyme’s Lemtrada didn’t include AAC because of the low number of cases observed during clinical trials testing the therapy.

Based on a small case series of AAC associated with Lemtrada use in RRMS patients, the FDA’s Division of Pharmacovigilance conducted a review to evaluate AAC as a potential safety risk for patients taking the therapy.
