Oral laquinimod for multiple sclerosis treatment significantly reduced disease activity and disability progression while providing good safety and tolerability
Teva Announces Updated Time For Webcast To Discuss Study Results On April 11th, 7:00 p.m. EDT
- Phase III ALLEGRO study met primary endpoint and key secondary endpoints:
- 23 percent reduction in annualized relapse rate
- 36 percent reduction in sustained disability progression
- 33 percent reduction in brain atrophy
- Safe and well-tolerated therapy without immunosuppressive effects
- Additional new pre-clinical data demonstrate potential neuroprotective mechanism of action of laquinimod
Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA) and Active Biotech (NASDAQ OMX NORDIC: ACTI) announced today results from the two-year Phase III ALLEGRO study of laquinimod, an oral, once-daily, investigational immunomodulator for the treatment of relapsing forms of multiple sclerosis (MS). These data will be presented as late-breaking research at the Annual Meeting of the American Academy of Neurology (AAN).
In the ALLEGRO study, laquinimod showed a statistically significant 23 percent reduction in annualized relapse rate (p=0.0024), the primary endpoint, along with a significant 36 percent reduction in the risk of confirmed disability progression, as measured by Expanded Disability Status Scale (EDSS) (p=0.0122). Treatment with laquinimod was also associated with a significant reduction in brain tissue loss, as measured by a 33 percent reduction in progression of brain atrophy (p<0.0001).
"The ALLEGRO study results are exciting, as they suggest that oral laquinimod is a novel therapeutic option that safely slows MS disease activity and progression," said Principal Investigator, Professor Giancarlo Comi, Director of the Department of Neurology and Institute of Experimental Neurology at the University Vite Salute, San Raffaele, Italy. "Additional pre-clinical data presented at this meeting suggest that oral laquinimod exerts a novel and protective mechanism of action within the central nervous system to significantly reduce the main neurological damage of the disease."
Laquinimod was safe and well-tolerated without immunosuppressive effects. The overall frequencies of adverse events, including incidence of infections, were comparable to those observed in the placebo group. The most commonly reported adverse events were headaches, nasopharyngitis and back pain. The incidence of liver enzyme elevation was higher in laquinimod treated patients; however, these elevations were transient, asymptomatic and reversible. No deaths were reported in laquinimod-treated patients.
The positive ALLEGRO results are supported by new pre-clinical data, also presented at the AAN meeting, that further establish the mechanism of action (MOA) of laquinimod, which led to a reduction in axonal damage, the main determinant of permanent clinical disability in MS. Data from the cuprizone model, designed to investigate the effect on neurodegeneration, independent of inflammation, demonstrated that laquinimod reduced demyelination and axonal damage while preserving more myelin-producing cells. This unique effect suggests a direct decrease in nerve damage in the central nervous system (CNS). Additionally, laquinimod was shown to modulate the brain-derived neurotrophic factor (BDNF) pathway, a key factor in maintaining axonal integrity.
"We are very enthusiastic about the results of the ALLEGRO study, which demonstrated that laquinimod significantly slows the progression of disability, the primary goal of MS treatment. Given the efficacy, safety and tolerability data to date, laquinimod may present a very promising treatment option to the MS community," said Professor Yitzhak Peterburg, Teva's Group Vice President, Global Branded Products.
The second laquinimod Phase III study, BRAVO, is currently ongoing with results anticipated in the third quarter of 2011. Regulatory submissions are planned in the U.S. and the EU following the availability of the BRAVO results.
Teva Pharmaceutical Industries Ltd. (Nasdaq: TEVA) will host an audio webcast on April 11th, 2011 at 7:00 p.m. EDT to present the results from the Phase III ALLEGRO study of laquinimod. Those interested in listening to the webcast should log on to http://www.tevapharm.com/... and register for the event (approximately 10 minutes before). The dial-in for this call is 1-800-215-2410 or 617-597-5410 internationally. The conference ID or passcode is 14479443. An archive of the webcast will be available on Teva's website.
ABOUT THE ALLEGRO STUDY
ALLEGRO was a two-year multi-national, multi-center randomized, double blind, placebo-controlled study designed to evaluate the efficacy, safety and tolerability of laquinimod in MS patients. The study was conducted at 139 sites in 24 countries and enrolled 1,106 MS patients. Patients were randomized to receive a once-daily oral dose of 0.6 mg laquinimod or matching placebo. The primary outcome measure was the number of confirmed relapses; secondary measures included confirmed disability progression and changes in MRI active lesions.
Eighty percent of laquinimod and 77 percent of placebo patients completed the two-year study. Patients who completed the ALLEGRO study were offered to join an open-label extension phase, in which they are being treated with laquinimod 0.6 mg daily.
Laquinimod is an oral, once-daily, immunomodulator with a novel mechanism of action being developed for the treatment of MS. The global Phase III clinical development program evaluating oral laquinimod in MS consists of two pivotal studies, ALLEGRO and BRAVO. BRAVO, is a two-year, multi-national, multi-center, randomized, double-blind, parallel-group, placebo-controlled study designed to compare the safety, efficacy and tolerability of a once-daily oral dose of 0.6 mg laquinimod over placebo and to perform a comparative risk-benefit assessment between laquinimod and interferon beta-1a. Enrollment of 1,332 patients at 154 sites in the U.S, Europe, Israel and South Africa was completed in June 2009. BRAVO study results are anticipated in the third quarter of 2011.
In addition to the ongoing MS clinical studies, laquinimod is currently in Phase II development for Crohn's disease and Lupus, and is being studied in other autoimmune diseases.
ABOUT 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. Multiple sclerosis is a degenerative disease of the central nervous system in which inflammation and axonal damage and loss result in the development of progressive disability.
