In clinical trials of Aubagio, cancer was not a side effect that occurred. However, in a case report, a woman with multiple sclerosis (MS) developed follicular lymphoma after taking Aubagio for 8 months. The report did not claim that Aubagio was the cause of the cancer, but it did not rule out that possibility.
In Aubagio clinical trials, four people died from heart problems. This was out of about 2,600 people taking the drug. However, it wasn’t shown that taking Aubagio caused these deaths.
