Good shout JoH and found this passage rather alarming.
“Therefore, the approval by the FDA of Ocrelizumab, which should have almost identical anti-B cell activity to Rituximab, appears to be good news for MS patients. However, there are some serious concerns with Ocrelizumab that patients need to be made aware before they consider this therapy. First, in the RRMS trial, there were 9 patients who developed various malignancies within three years of taking Ocrelizumab (4 patients within the first 2 years and 5 patients in the following year). This is alarmingly high considering that these patients were mostly in their third decade of life and had no previous history of cancer. In the trial for PPMS patients, 13 patients developed cancer within the three years of taking Ocrelizumab (11 in the first two years and 2 additional cases in the following year). This means that more than 1 in 50 patients developed cancer within three years of taking Ocrelizumab among the PPMS patients. These risks of malignancy associated with Ocrelizumab are not seen with Rituximab (more than a thousand patients just at our center since 2001 and several hundred thousand worldwide). This risk of cancer with Ocrelizumab is not explained at present and the magnitude of the problem cannot be defined, as the medication has not been given for a period longer than 3 years.”
