Laquinimod is an experimental immunomodulator developed by Active Biotech and Teva. It is currently being investigated as an oral treatment for multiple sclerosis (MS).
Laquinimod is the successor of Active Biotech's failed experimental immunomodulator linomide.[1]
The compound has been investigated in two Phase II trials using successive magnetic resonance scans (MRI). Laquinimod seems to be able to reduce the MS disease activity on MRI.[2][3] However, the response to a given dose was discrepant between both studies.[4]
Phase III studies for Multiple Sclerosis started in December 2007 [5] but in 2011 Teva announced that its clinical trials involving Laquinimod had failed, being unable to significantly reduce relapses into multiple sclerosis among patients beyond what a placebo was.[6]
