|Teva and Active Biotech Announce Expansion of Laquinimod Clinical Development Program with New Trial in Primary Progressive Multiple Sclerosis and First Patient Screened in Huntington’s Disease Trial|
ARPEGGIO and LEGATO-HD trials will further evaluate the effect of laquinimod in neurodegenerative diseases
“Teva prides itself in striving to help patients with neurodegenerative
diseases through research and innovation,” said
The ARPEGGIO study will evaluate the efficacy, safety and tolerability of laquinimod in patients with PPMS with a primary endpoint of percent brain volume change (PBVC) through MRI analysis. PPMS is characterized by the worsening of neurologic function without distinct relapses (also called attacks or exacerbations). Approximately 15 percent of MS patients fall into the PPMS category.
The LEGATO-HD study will evaluate the efficacy, safety and tolerability of once-daily oral laquinimod as a potential treatment for adult patients with Huntington’s disease. The primary endpoint for LEGATO-HD is change from baseline in the Unified Huntington’s Disease Rating Scale-Total Motor Scale (UHDRS-TMS) as defined by the sum of the scores of all UHDRS-TMS sub-items after 12 months of treatment. Huntington’s disease is caused by a genetically-programmed degeneration of brain cells in select areas of the brain, which results in uncontrolled movements, loss of intellectual faculties and personality and emotional disturbances. Huntington’s disease affects about five to seven people per 100,000 in Western countries.

The study, A Randomized Placebo-controlled Trial Evaluating Laquinimod in PPMS, Gauging Gradations In MRI and Clinical Outcomes (ARPEGGIO) is a multinational, multicenter, randomized, double-blind, parallel-group, placebo-controlled, Phase II clinical trial.
ARPEGGIO is intended to serve as a proof-of-concept study for potential treatment with laquinimod in PPMS. The trial will evaluate two doses of laquinimod (0.6 and 1.5mg/day) in PPMS compared to placebo. The primary endpoint of the study is brain atrophy as defined by PBVC from baseline to week 48. Secondary endpoints include time to confirmed disability progression, the number of new T2 lesions and change in the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) score. ARPEGGIO has an estimated completion date of H2 2017.
LEGATO-HD (Laquinimod Efficacy and Safety in a GlobAl Trial Of HD) is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of laquinimod treatment at doses of 0.5, 1.0, and 1.5 mg/day in 400 adult Huntington’s disease patients between the ages of 21-55. Ancillary studies will evaluate microglia activation, neuronal integrity, and peripheral inflammatory biomarkers. LEGATO-HD has an estimated completion date of H1 2017.
The primary endpoint of LEGATO-HD is change from baseline in the Unified Huntington’s Disease Rating Scale-Total Motor Scale (UHDRS-TMS) as defined by the sum of the scores of all UHDRS-TMS sub-items after 12 months of treatment. Secondary endpoints will measure brain atrophy, cognition, clinical global impression and functional capacity.
Laquinimod is a once-daily oral, investigational, CNS-active immunomodulator with a novel mechanism of action being developed for the treatment of relapsing-remitting MS (RRMS), progressive MS and Huntington’s disease. The global, Phase III, clinical development program evaluating laquinimod in MS includes two completed pivotal studies, ALLEGRO and BRAVO (both 0.6mg/day). A third Phase III trial, CONCERTO, is currently ongoing and evaluating two doses of laquinimod (0.6mg and 1.2mg/day) in approximately 2,100 patients for up to 24 months. The primary outcome measure is time to three-month confirmed-disability progression as measured by the Expanded Disability Status Scale (EDSS).
In the ALLEGRO and BRAVO trials, adverse reactions observed included headache, abdominal pain, back and neck pain, appendicitis, and mild, asymptomatic laboratory abnormalities, including liver enzyme elevations, hematological changes and elevation of CRP or fibrinogen levels.
