7:31AM Chelsea Therapeutics reports positive interim analysis of Phase II Trial of Droxidopa in Fibromyalgia (CHTP) 2.93 : The co announces the completion and favorable outcome of an independent Data Monitoring Committee (DMC) review of the safety and efficacy data from approximately half the target enrollment in Chelsea's Phase II trial of droxidopa in fibromyalgia... Following their assessment of each of the 12 arms using the study's primary endpoint, a reduction in pain as measured by the Short Form McGill Pain Questionnaire, the DMC recommended that 7 of the 12 arms of the trial be continued to completion. This recommendation was based solely on their efficacy analysis, as there were no observed safety concerns associated with any arm of the study. As a result of this recommendation, the study will now focus primarily on multiple doses of droxidopa in combination with 50mg carbidopa.
