Memory Pharmaceuticals Reports Phase 2a Results for MEM 1003 in Bipolar DisorderCompany to Host Conference Call at 9:00 a.m. to Discuss Results
MONTVALE, N.J., March 05, 2007 /PRNewswire-FirstCall/ -- Memory Pharmaceuticals Corp. today announced top-line data from the Phase 2a study of MEM 1003 in acute mania in bipolar disorder, which was conducted with funding support from the Stanley Medical Research Institute. An analysis of the primary and secondary outcome measures in the trial indicated that MEM 1003 did not prove effective for the treatment of bipolar mania. MEM 1003 was safe and generally well-tolerated in the study.
The multi-center, double-blind, randomized, placebo-controlled study evaluated the safety and efficacy of MEM 1003 for the treatment of acute mania in bipolar disorder. Eighty-four subjects were randomized to receive MEM 1003 or placebo for a 21-day treatment period, which was followed by an optional open-label four-week treatment period. The primary outcome measure was a comparison of the percentage of subjects in the placebo and MEM 1003 treatment groups with at least 50% improvement from baseline in the Young Mania Rating Scale (YMRS) at 21 days. The secondary outcome measures were the mean change from baseline in the YMRS, the Modified Clinical Global Impression - Bipolar Scale and the Montgomery-Asberg Depression Rating Scale at 21 days. None of these outcome measures was achieved.
There were no serious adverse events reported in the MEM 1003 treatment group during the study, in contrast to three serious adverse events of worsening of mania reported in the placebo treatment group. The most commonly reported adverse events in the MEM 1003 treatment arm of the trial were headache, gastrointestinal effects and pruritus (or itching).
"We are obviously disappointed that MEM 1003 did not prove effective in the treatment of mania in our study," said Stephen R. Murray, M.D., Ph.D., Vice President of Clinical Development. "However, the target symptoms and the nature of the assessments in our ongoing Phase 2a study in Alzheimer's disease are very different from those in this mania study, and we do not believe that the negative results in this study are predictive of the effects of MEM 1003 in Alzheimer's disease."
"Memory Pharmaceuticals has completed a high quality study," said Gary S. Sachs, M.D., Associate Professor in Psychiatry, Harvard Medical School and Director, Bipolar Mood Disorder Program at Massachusetts General Hospital and Principal Investigator on the Phase 2a trial of MEM 1003 in bipolar disorder. "Although the maximum dose allowed in the study proved well-tolerated, the results clearly showed no difference in efficacy endpoints at day 21 between MEM 1003 and placebo."
"We are committed to finishing the ongoing Phase 2a study in Alzheimer's disease and expect results in the fourth quarter of this year," said David A. Lowe, Ph.D., Chief Scientific Officer. "We are currently completing a full analysis of the bipolar results in order to learn as much as we can from this data set."
