FDA Rescinds Teva SPA After Dosing Changed

Share

FDA has told Teva Pharmaceutical Industries that a previously agreed to Special Protocol Assessment (SPA) has been rescinded for the Phase 3 CONCERTO clinical trial evaluating laquinimod in relapsing remitting multiple sclerosis (MS). Earlier this year, Teva and its development partner Active Biotech confirmed that the highest dose arms in two MS trials and one trial in Huntington’s Disease were discontinued at the recommendation of a data monitoring committees. Subsequently, Teva submitted an amendment to the SPA to account for this change. However, under FDA’s regulatory process, the SPA was rescinded as all changes must be agreed to prior to implementation of the change. “This requirement could not be fulfilled in the current case, since the DMC recommendation triggered an immediate action to withdraw the 1.2 mg dose for the treatment of RRMS in the interest of patient safety” Active Biotech says.

The CONCERTO trial continues with one dose (0.6mg/day) vs. placebo on the original schedule, and Teva plans to use this pivotal study to support filing for marketing approval for laquinimod in the U.S. and EU. Teva has completed two Phase 3 trials with the 0.6mg daily dose in MS and continues long-term extension studies at this dose.
