Also, first“An effective oral line treatments decrease treatment would be a relapses by only about 30%, he said. true breakthrough for Comi described results MS patients, and it of an extension study in 173 patients with relapsappears we may be ing MS who have thus close to that goal,” says far completed three years of FTY720 treatment folGiancarlo Comi, M.D. lowing a six-month study in which they had been assigned to the experimental drug or placebo. After six months, patients treated with FTY720 had more than 50% fewer relapses than the placebo-treated group. After three years, 73% of patients initially assigned to FTY720 at 5 mg/d and 68% assigned to a 1.25 mg/d dose were relapse-free. Because of comparable efficacy and a superior safety profile, all patients have been switched to the lower dose for the ongoing extension study. Magnetic resonance imaging (MRI) showed that the inflammatory activity associated with MS remained low. Overall, 89% of patients had no disease activity and 75% had no new or newly enlarged lesions. The most common treatment-related side effects were headache, fatigue, flu, and cold symptoms. There were also seven cases of skin cancer. “An effective oral treatment would be a true breakthrough for MS patients, and it appears we may be close to that goal,” Comi said. FTY720 is an oral sphingosine 1phosphate (S1P) receptor modulator. Other studies presented at AAN covered the following: M Parkinson’s disease Levodopa/carbidopa/entacapone (LCE) (Stalevo, Orion) improves symptoms in patients with early Parkinson’s disease (PD) more than levodopa/carbidopa (LC, Sinemet, Bristol-Myers Squibb), the treatment standard, according to the results of a Phase III trial. Robert Hauser, M.D., professor of neurology at the University of South Florida in Tampa, reported data in 423 patients who had been randomized to fixeddose LCE 100/25/200 mg or LC 100/25 mg tid for 39 weeks. Levodopa/carbidopa/entacapone demonstrated a significant improvement over levodopa/carbidopa in the primary outcome measure, which was the change in combined Unified PD Rating Scale (UPDRS) Part II activities of daily living (ADL) and Part III motor scores. Significantly, the improvement with the triple-drug combination occurred without an increase in motor complications, Hauser noted. Levodopa/ carbidopa/entacapone is indicated for patients with advanced PD experiencing wearing-off. Diabetic neuropathic pain The investigational agent lacosamide (UCB Pharma) is effective and well tolerated when used to treat diabetic neuropathic pain, a recent analysis shows. Aziz Shaibani, M.D., clinical assistant professor of medicine at Baylor College of Medicine in Houston, reported pooled efficacy and safety data in patients treated with lacosamide, 400 mg/d, versus placebo, in three, 12-week Phase III trials. Results showed a mean 2.5 point decrease in pain on the 11-point Likert scale at the end of treatment in the 285 lacosamide-treated patients versus a 1.8 point decrease in the 88 placebo-treated patients. About a third of the lacosamide cohort reported 50% or more pain reduction. Most patients had used prior medications for diabetic neuropathic pain, and most of them had responded poorly to such treatments. Treatment-related side effects observed more often with lacosamide included dizziness, fatigue, nausea, and tremor. Lacosamide did not lengthen the QT interval or cause significant leg or foot edema or sleepiness, all of which are frequently reported with common treatments for diabetic neuropathic pain.
