Lilly and BioMS Medical reported that their investigational agent dirucotide did not meet the primary end point of delaying disease progression in patients with secondary progressive multiple sclerosis (SPMS) in the phase 3 MAESTRO-01 trial.

Lilly and BioMS Medical reported that their investigational agent dirucotide did not meet the primary end point of delaying disease progression in patients with secondary progressive multiple sclerosis (SPMS) in the phase 3 MAESTRO-01 trial. Dirucotide and placebo also did not differ significantly on any secondary end points in the trial.

The companies have announced that they are discontinuing ongoing clinical trials of dirucotide for the treatment of SPMS (including MAESTRO-02 and MAESTRO-03) and will review the available data before deciding on how to move forward.

No unexpected safety or tolerability issues were reported in the MAESTRO-01 trial.

FDA granted dirucotide fast-track status for the treatment of SPMS in September 2008.
