Extina® Foam 2%
|The US FDA approved this product in July 2007 for the topical treatment of seborrheic dermatitis in immunocompetent patients 12 years of age and older. Extina® is administered using VersaFoam® HF® technology, a topical drug delivery vehicle that is quickly absorbed into the skin. Studies show consistent skin permeation, drug distribution, and drug delivery.
Treatment for Lupus Nephritis
|In June 2007 Aspreva Pharmaceuticals and Roche released preliminary results for a clinical trial comparing oral mycophenolate mofetil (MMF) (CellCept®) with IV cyclophosphamide (IVC), which is the current standard of care for inducing treatment response in the induction phase of patients suffering from lupus nephritis. Although response rates were similar in both arms, the trial did not meet its primary objective of demonstrating that MMF was superior to IVC in inducing treatment response in this disease. Additional analyses are ongoing to determine the potential for a regulatory submission.
|According to an addendum in The Medical Letter*, some consultants for the publication have suggested that their recent article on dermal fillers (Dermal Fillers. Med Lett Drugs Ther 49(1260):39-40 ) should have included stronger warnings about the risk of fillers that are not biodegradable, such as Artefill®. Even with the best technique, the polymethylmethacrylate (PMMA) beads in this product can, over time, cause foreign-body granulomas and hypertrophic scarring, which may require surgical removal. Granulomas and nodules have been especially frequent when Artefill® was injected into the lips. Complications are less likely with hyaluronic acid products such as Hylaform®, Juvederm®, or Restylane®.
