October 29, 2012
Teva Pharmaceutical released results from a phase IIa trial of laquinimod for Crohn’s disease (CD). This multi-center, randomized, double-blind, placebo-controlled study enrolled 180 patients with moderate to severe 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. Subjects received daily doses of laquinimod 0.5mg, 1mg, 1.5mg, 2mg, or placebo for eight weeks, with four weeks follow-up. Data demonstrated that laquinimod 0.5mg/day resulted in a robust, early and consistent effect on remission (48.3% versus 15.9% of patients, respectively) and response rates (62.1% versus 34.9% of patients, respectively) versus placebo. No effect was noted on remission/response at higher doses. The drug was well tolerated.

Novogen has issued positive results of a phase I trial of their investigational synthetic isoflavone analogue NV-52, for the treatment of inflammatory bowel disease. Pharmacokinetic results indicated a rapid absorption profile and fairly consistent bioavailability, with peak plasma concentration achieved approximately 4 hours after administration, and a plasma elimination half-life of 8 hours. In addition, safety data yielded no reported adverse events. This open-label study enrolled 6 healthy male volunteers at the Gold Coast Hospital in Australia, under the direction of Professor Laurie Howes. Subjects received single oral administrations of the drug.

Adolor reported positive results from a phase III trial investigating alvimopan for the treatment of opioid bowel dysfunction. The study enrolled 168 chronic users of opioids whose bowel function had been impaired. The primary endpoint, the proportion of subjects having a bowel movement within 8 hours after each dose compared to placebo reached statistical significance. The proportion of subjects who had at least one bowel movement was 43% for alvimopan (0.5 mg), 55% for alvimopan (1 mg) and 29% for placebo. Alvimopan was well tolerated and the most frequently occurring adverse events versus placebo, included, diarrhea, abdominal cramps, nausea and vomiting.

Positive results were reported from a phase I trial of NicOx's NCX 1015, a nitric oxide-releasing derivative of prednisolone being developed for the treatment of inflammatory bowel disease. The randomized, double-blind, placebo-controlled, parallel-group study evaluated a local delivery (enema) formulation of NCX 1015. Four single escalating doses of NCX 1015 were administered to healthy male volunteers. Thirty-two subjects were divided into groups of eight; in each group, six subjects received NCX 1015 and two received placebo. Results showed satisfactory overall safety and tolerability of the drug, and no serious or severe adverse events were reported.
