Safety Issues Clinical Trial
Official title:
A Phase I, Double-blind, Randomised, Placebo-controlled, Single-ascending and Multiple-ascending Dose Trial to Evaluate Safety and Pharmacokinetics of Oral Controlled-ileocolonic-release Nicotinamide (CICR-NAM) Compared to Immediate-release Nicotinamide and Placebo in Healthy Subjects and in Patients With Inflammatory Bowel Diseases
Double-blind, randomised, placebo-controlled phase I trial with single-ascending and multiple-ascending dose to evaluate safety and pharmacokinetics of oral controlled-ileocolonic-release nicotinamide (CICR-NAM) compared to immediate-release nicotinamide and placebo in healthy subjects and in patients with inflammatory bowel diseases.
Nicotinamide (NAM) has been implicated in the restoration and maintenance of a healthy gut microbiome. Conventional NAM formulations are designed for systemic NAM supplementation and therefore release NAM in the stomach and upper small intestine for maximum absorption. In contrast, the novel CICR-NAM tablets (controlled-ileocolonic-release nicotinamide) start releasing in the lower small intestine for topical delivery of NAM to the microbiota and the mucosa in the ileum and colon, also leading to a reduced systemic exposure. This clinical Phase I trial investigates the safety and tolerability of CICR-NAM in single- and multiple-ascending doses (1, 2 and 4 g). At the beginning of the trial, single-dose pharmacokinetics (PK) of 1 g of conventional immediate-release NAM and CICR-NAM are compared. At the end of the trial, patients with inflammatory bowel diseases (IBD) receive a medium multiple dose (2 g for 4 weeks) to compare their exposure, PK and safety data with those of healthy subjects at the same dose level. ;
