|Phase IIa Laquinimod Trial Results Show Positive Data for Potential Use in Active Crohn's Disease|
Newly Presented Data at 20th United European Gastroenterology (UEG) Week Conference Show Significant Impact of Laquinimod on Clinical Remission versus Placebo
The full abstract can be found at:
“Our developmental program for laquinimod has demonstrated that the
immunomodulatory effects of this oral compound stand to apply to
multiple autoimmune diseases, and data presented at UEG showed an
impressive impact on clinical remission in Crohn’s disease as early as
one week of treatment,” said Dr.
The Phase IIa study evaluated the safety and efficacy of various doses of laquinimod (0.5, 1, 1.5, or 2 mg/day) compared to placebo in active CD over eight weeks of treatment with four weeks of follow up. No effect was noted on remission/response at higher doses. Additionally, laquinimod 0.5 mg and 1 mg doses were generally well-tolerated, with adverse events similar to those seen with placebo. The data are currently undergoing further analysis and evaluation to finalize next steps in the CD clinical development plan.
ABOUT THE STUDY
The Phase IIa, multicenter, randomized, double-blind, placebo-controlled trial was designed to evaluate the safety and efficacy of laquinimod in 180 patients with moderate to severe active CD, based on a CD Activity Index (CDAI) of 220-450 and serum C-reactive protein (CRP) levels of >5mg/L or mucosal ulcerations evident on a recent endoscopy. The study tracked four dose cohorts who received laquinimod 0.5 mg/day, 1 mg/day, 1.5 mg/day, 2 mg/day, or placebo for eight weeks with four weeks follow-up. Approximately 45 patients were enrolled in each cohort in a 2:1 ration between laquinimod and placebo. Stable concomitant therapies and prior anti-tumor necrosis factor (TNF) use among patients was permitted in the study.
Laquinimod is a novel oral immunomodulator under clinical development for the treatment of multiple sclerosis (MS), Crohn’s disease (CD) and systemic lupus erythematosus (SLE or lupus). Human and animal models suggest laquinimod exerts its therapeutic effect by modulating the immune system cells, mainly resulting in a down regulation of pro-inflammatory cytokines.
ABOUT CROHN’S DISEASE
CD is a chronic inflammatory condition that affects the gastrointestinal tract. The symptoms of CD can vary significantly among afflicted individuals. The main gastrointestinal symptoms are abdominal pain, diarrhea, or weight loss. CD can also cause complications outside of the gastrointestinal tract such as skin rashes, arthritis, and inflammation of the eye.
The precise cause of CD is not known. CD is considered to be an autoimmune disease. This autoimmune activity produces inflammation in the gastrointestinal tract. CD is classified as an inflammatory bowel disease, IBD.
