Raptiva (efalizumab)

FDA issued a Public Health Advisory to notify healthcare professionals of three confirmed, and one possible report of progressive multifocal leukoencephalopathy (PML), a rare brain infection, in patients using the psoriasis drug Raptiva. In October 2008, the labeling for Raptiva was changed to highlight, in a Boxed Warning, the risks of life-threatening infections, including PML. In addition, FDA directed Genentech, the manufacturer of Raptiva, to develop a Risk Evaluation and Mitigation Strategy, or REMS, to ensure that patients receive risk information about Raptiva. The FDA is reviewing this latest information. The agency will take appropriate steps to ensure that the risks of Raptiva do not outweigh its benefits, that patients prescribed Raptiva are clearly informed of the signs and symptoms of PML, and that health care professionals carefully monitor patients for the possible development of PML. The Public Health Advisory provides recommendations for healthcare providers and patients when treatment with this product is considered.

Efalizumab (Raptiva)

FDA notified healthcare professionals of extensive labeling changes, including a Boxed Warning, to highlight the risks of life-threatening infections, including bacterial sepsis, viral meningitis, invasive fungal disease, progressive multifocal leukoencephalopathy and other opportunistic infections with the use of Raptiva. In addition, the prescribing information will be updated to describe a potential risk for the permanent suppression of the immune system with repeat administration of Raptiva in children. Raptiva is not approved for children under 18 years of age. Doctors and other prescribers should carefully evaluate and weigh the risk/benefit profile of Raptiva for patients who would be more susceptible to these risks. Health care professionals should monitor patients treated with Raptiva for the signs and symptoms of these adverse events and also instruct patients to report any such signs and symptoms to them without delay. Patients identified to begin therapy with Raptiva should have received all their age-appropriate vaccinations before starting the drug.Patients with pre-existing infections or who have a compromised immune system should notify their health care professional before beginning treatment with Raptiva.
