Drug News

In February 2009, The US FDA notified the manufacturers of licensed botulinum toxin (BTX) products that there is a need to strengthen warnings in product labeling and add a boxed warning that details the risk of adverse events when the effects of the toxin spread beyond the injection site. In addition, the FDA has advised the manufacturers that development and implementation of a Risk Evaluation and Mitigation Strategy is necessary to ensure that the benefits of the product outweigh the risks. This strategy would include a communication plan to provide more information about the risk for distant spread of the BTX effects after local injection, as well as information to explain that BTX products cannot be interchanged. This strategy would also include a medication guide that explains the risks to patients, their families and caregivers. The FDA is requiring the manufacturers to submit safety data after multiple administrations of the product in a specified number of children and adults with spasticity to assess the signal of serious risk regarding distant spread of toxin effects. BTX products are FDA-approved for temporary improvement in the appearance of glabellar lines, treatment of strabismus, blepharospasm, cervical dystonia, and primary axillary hyperhidrosis. The FDA urges both healthcare professionals and patients to report side-effects from these products to the FDA’s MedWatch Adverse Event Reporting Program, online at www.fda.gov/medwatch/report.htm.

Trubion Pharmaceuticals, in collaboration with Wyeth Pharamaceuticals, announced in March 2009 that it has initiated a Phase I/II dose-escalation clinical trial for SBI-087, a humanized small modular immunopharmaceutical drug candidate that acts against the CD20 antigen, for the treatment of systemic lupus erythematosus (SLE). The study will enroll patients who were diagnosed with SLE more than 6 months before the beginning of the study. Diagnosis is based on the American College of Rheumatology Revised Criteria. In preclinical data, a single dose of SBI-087 resulted in dose-dependent B-lymphocyte depletion in peripheral blood and lymphoid tissues that was more profound and sustained when compared with rituximab.
