Laquinimod Demonstrated Significant and Sustained Impact on Multiple Sclerosis Disease Activity

New Crossover Data Presented at the World Congress on Treatment and Research in Multiple Sclerosis Shows Significant Reduction of Gadolinium-Enhancing Lesions

JERUSALEM & LUND, Sweden--(HSMN NewsFeed)--New data from the extension phase of oral laquinimod in relapsing-remitting multiple sclerosis (RRMS) demonstrated a significant reduction in the mean number of gadolinium-enhancing (GdE) lesions in both patients who switched from placebo to laquinimod and patients who continued with their initial laquinimod dose. In RRMS patients who switched from placebo to laquinimod, 52 percent reduction in the mean number of GdE lesions was observed (p<0.0007). The reduction was significant for both patients switching to high-dose (p<0.009) and low-dose laquinimod (p<0.03). In addition, the proportion of patients who switched to active treatment from placebo, and remained enhancing lesion-free, increased from 31 percent to 47 percent (p<0.012), further reinforcing the efficacy of laquinimod on magnetic resonance imaging (MRI) measured disease activity.

Patients initially treated with 0.6mg/day and 0.3mg/day during the double-blind trial remained on the same dose during the 36-week extension phase. An additional significant reduction in the mean number of GdE lesions was also observed in these patients (n=94, p=0.0062 and n=80, p=0.0013, respectively), a high proportion of which remained completely free of GdE lesions, demonstrating the sustained effect of laquinimod on MRI disease activity.

“These latest data show the rapid onset and sustainability of laquinimod efficacy in MS patients,” said Giancarlo Comi, M.D., University Vita-Salute San Raffaele, Scientific Institute San Raffaele, Milan, Italy, principal investigator of the study. “Just as exciting is the fact that, with increased number of patients exposed to laquinimod, we found no new risks or safety issues. This reinforces earlier results demonstrating the laquinimod safety profile. The MS community looks forward to future data as we continue enrolling patients in the laquinimod Phase III clinical program.”

These new data from the extension study build upon the initial 36-week, Phase IIb study results published in The Lancet*, which demonstrated that once-daily, oral 0.6mg laquinimod significantly reduced MRI disease activity by a median of 60 percent, compared to placebo, and was well tolerated.

Teva is currently enrolling patients for Allegro and Bravo, two pivotal Phase III clinical trials of laquinimod. For more information please visit

About the Study

In the study, “Oral laquinimod in patients with relapsing–remitting multiple sclerosis: 36 weeks double-blind active extension of the multi-center, randomized, double-blind, parallel-group placebo-controlled study,” subjects originally assigned to placebo were equally randomized to receive either 0.3 or 0.6mg/day laquinimod, while others continued their original treatment for a 36-week, double-blind extension. Magnetic resonance imaging (MRI) was performed at the beginning and at the end of the active extension phase. The mean number of GdE lesions in patients who switched from placebo to laquinimod was reduced by 52 percent (from 4.46±6.55 to 2.12±3.73; p<0.0007) from the time patients began receiving active treatment.

Two hundred and fifty seven patients (91 percent) entered the extension phase to receive laquinimod 0.3mg/day or 0.6mg/day. Neither new safety signals nor an increase in the incidence rate of adverse events and laboratory abnormalities have emerged following new or prolonged exposure to laquinimod.

Patients on continuous 18 month laquinimod 0.6mg treatment continued to show low MRI disease activity, with a high proportion remaining free of GdE-lesions. A good tolerability profile was also observed. Treatment effects on MRI activity witnessed during the placebo-controlled phase were reproduced when placebo patients switched to laquinimod.

About Multiple Sclerosis

Multiple Sclerosis (MS) is the leading cause of neurological disability in young adults. It is estimated that more than 400,000 people in the United States are affected by the disease and that two million people may be affected worldwide. MS is a progressive, demyelinating disease of the central nervous system affecting the brain, spinal cord and optic nerves. Demyelination is the destructive breakdown of the fatty tissue that protects nerve endings.

About Laquinimod

Laquinimod is a novel once-daily, orally administered immunomodulatory compound that is 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 recently published in The Lancet and demonstrated that an oral 0.6 mg dose of laquinimod, administered daily, significantly reduced MRI disease activity by a median of 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. Over 480 MS patients have received laquinimod in various clinical trials.

In addition to the efficacy that laquinimod has shown in Phase II RRMS clinical trials, laquinimod has demonstrated potent therapeutic efficacy in preclinical models of other autoimmune diseases such as rheumatoid arthritis, insulin-dependent diabetes mellitus, Guillain Barré Syndrome, lupus and Inflammatory Bowel Disease. The broad profile of efficacy in animal models of inflammatory diseases suggests that laquinimod affects a pivotal pathway of inflammation and autoimmunity. Teva expects to initiate the clinical development of laquinimod for Crohn’s disease and Lupus Nephritis in the near future.

About the Phase III Program

Allegro (assessment of oral laquinimod in preventing progression of MS) is a pivotal, global, 24/30-month, double-blind, Phase III study designed to evaluate the efficacy, safety and tolerability of laquinimod versus placebo in the treatment of RRMS. The enrollment goal is approximately 1,000 patients with RRMS.

Bravo (benefit-risk assessment of Avonex® and laquinimod) is a pivotal, multinational, multi-center, randomized, double-blind, parallel-group, placebo-controlled study designed to compare the safety and efficacy of laquinimod with placebo and to provide risk-benefit data for laquinimod versus a currently available injectable treatment. The enrollment goal is approximately 1,200 patients with RRMS.

The globally conducted clinical program will include centers throughout the United States as well as centers Canada, Europe, and Israel. To learn more about the research please visit or call 1-866-550-0614 (Allegro) or 1-800-840-5601 (Bravo).
