Oral Laquinimod Demonstrated Sustained Efficacy and Safety in Patients with Multiple Sclerosis

  • Positive benefit-risk profile of laquinimod sustained in Phase II extension study
  • 52 percent reduction (p=0.0006) in mean number of gadolinium-enhancing (GdE) T1 lesions
  • Results from pivotal Phase III studies, ALLEGRO and BRAVO, anticipated in 2011

JERUSALEM--(BUSINESS WIRE)-- Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA) and Active Biotech (NASDAQ OMX NORDIC: ACTI) today announced results from a 36-week active extension study evaluating two doses of laquinimod, an investigational, once-daily oral immunomodulator, for the treatment of relapsing remitting multiple sclerosis (RRMS). The double-blind, multinational study demonstrated the sustained positive benefit-risk profile of laquinimod, which was shown to reduce Gd-enhancing (GdE) T1 lesions, while maintaining a good safety profile. These findings were published online by the journal Multiple Sclerosis.

Patients originally randomized to placebo in the core Phase II study, LAQ/5062, (published in The Lancet*) were re-randomized to either 0.3 mg or 0.6 mg laquinimod for the extension study, while patients originally randomized to active treatment continued with the same treatment assignment for an additional 36 weeks. Patients switching from placebo to an active treatment of laquinimod showed a 52 percent reduction in the mean number of GdE lesions (p=0.0006), a marker of disease activity. In patients initially randomized to 0.6 mg laquinimod, the reduction of MRI activity was maintained. Additionally, treatment with laquinimod was associated with a sustained reduction in relapse rate, no evidence of immunosuppression and good safety and tolerability profile.

“The results from this extension study confirm the balanced efficacy, safety, and tolerability profile seen with laquinimod to date,” explains Giancarlo Comi, M.D., the lead study author and the Director of the Department of Neurology and Institute of Experimental Neurology at the University Vite Salute, San Raffaele. “We look forward to the results of the Phase III ALLEGRO and BRAVO studies in 2011, and the potential of this novel agent to address the current unmet need for MS patients seeking a safe, effective and well tolerated oral therapy.”

Laquinimod received Fast Track designation from the U.S. Food and Drug Administration (FDA) in February 2009. Two global Phase III clinical studies, ALLEGRO and BRAVO are currently ongoing, with results anticipated during Q1 and Q3 2011, respectively.

The multinational, double-blind, 36-week extension of the placebo-controlled Phase IIb laquinimod study was conducted in 9 countries at 51 sites. Two hundred thirty-nine (93 percent) patients completed the extension phase of the study and 222 (87.1 percent) had a final scan. GdE lesions were significantly reduced for patients switching from placebo to 0.3 or 0.6 mg doses (52 percent, p = 0.0006). In patients initially randomized to 0.6 mg, the reduction of MRI activity observed in the placebo-controlled phase was maintained in the extension. The proportion of GdE-free patients for those who switched from placebo increased from a baseline of 31 percent to 47 percent at the end of the extension phase (p = 0.01). No new adverse events emerged during the extension study. The incidence rate of liver enzymes elevation observed in the LAQ/5062 core study decreased in the extension phase.


Laquinimod is an investigational, novel, once-daily oral immunomodulator being developed as a disease-modifying treatment for RRMS. Active Biotech developed laquinimod and licensed it to Teva Pharmaceutical Industries, Ltd. in June 2004. A Phase IIb study in 306 patients was published in The Lancet and demonstrated that an oral 0.6 mg dose of laquinimod, administered daily, significantly reduced MRI disease activity by 60 percent versus placebo in RRMS patients. In addition, the study showed a favorable trend toward reducing annual relapse rates and the number of relapse-free patients compared with placebo. Treatment was well tolerated, with only some transient and dose-dependent increases in liver enzymes reported.

Two pivotal, global Phase III studies of laquinimod for the treatment of RRMS, ALLEGRO and BRAVO, are nearing completion. ALLEGRO, a 24-month multinational, double-blind, placebo-controlled study, designed to evaluate the efficacy, safety and tolerability of laquinimod versus placebo in the treatment of RRMS, enrolled 1,106 patients and data from the study are expected in Q1 2011. BRAVO, a multinational, multi-center, randomized, parallel-group study designed to evaluate laquinimod compared to placebo, as well as to provide risk-benefit data for laquinimod compared to a currently available injectable treatment, Avonex®, has enrolled 1,332 patients and will be complete in Q3 2011.

In addition to the ongoing RRMS clinical studies, laquinimod is currently in Phase II development for Crohn’s disease and Lupus, and is being studied in other autoimmune diseases.
