Says UT-Houston Researcher
Stephen Tyring, M.D., Ph.D., clinical professor at The University of Texas Medical School at Houston, was the principal investigator for the two-year clinical study at 39 medical centers in the United States and Canada. “This study represents, to our knowledge, the longest continuous exposure of patients with psoriasis to 50 milligrams of etanercept biweekly, and provides further insights into the safety and efficacy of high-dose etanercept for the treatment of moderate to severe psoriasis,” said Tyring. Psoriasis, a chronic inflammatory skin disorder, usually requires long-term therapy. Right now, the Food and Drug Administration has approved etanercept for 12 weeks of continued use at the higher dosage. This phase 3, randomized, double-blind trial examined whether more than 12 weeks of use could be harmful to the patient, and whether they would see continued improvement. The study involved more than 600 patients, some using etanercept and others taking a placebo. The participants were examined every 12 weeks to evaluate their progress. “Patients responded within two weeks to etanercept, with statistically significant differences between the etanercept group and placebo groups at week 12, said Tyring. Study participants hit their peak of improvement around the 48th week. “We now know for those people who lose their efficacy around week 12 that continuing to take etanercept will help them maintain their psoriasis, without harmful side effects,” said Tyring. Etanercept (Enbrel ®) is manufactured by Amgen and Wyeth Pharmaceuticals. Co-authors of the Archives of Dermatology include: Kenneth B.
