Chronic pancreatitis (CP) is a progressive, fibro-inflammatory disease characterized by enzymatic autoactivation and subsequent fibrotic replacement of acinar cells. A significant proportion of patients develop pain, which may be due to many causes, including perineural inflammation, altered central processing of pain signals, parenchymal structural changes, and ductal obstruction. Currently there are no approved medical treatment options for CP-associated pain. NI-03 (camostat mesilate) is an orally administered serine protease inhibitor that reduces pancreatic enzyme activity and has been widely used for the treatment of CP-associated pain in Japan. The current study will assess the safety and efficacy of NI-03 for reduction of CP-associated pain in the USA.

METHODS:

The current study consists of two phases. First, a phase I study will be performed to establish the pharmacokinetics and safety profile over a 1-week period following a single dose (100, 200, or 300 mg). Subsequently, a phase II study will be performed consisting of a double-blind, randomized, controlled trial (RCT). This RCT will evaluate the efficacy of each of the three doses of NI-03 given three times daily compared to placebo over 28 days. A 7-day, single-blind, run-in period will precede the double-blind phase to assess baseline pain characteristics. The primary efficacy outcome is the average of worst daily pain scores (numeric rating scale of 0-10) over the terminal 7 days of the study period compared to baseline. Secondary efficacy outcomes include change in opioid dose and quality of life measures, and time to first rescue intravenous analgesic. Adverse events will be recorded.

DISCUSSION:

NI-03 has been used successfully and safely in Japan to treat CP-associated pain. The aim of the current study is to assess the safety and efficacy of NI-03 using a rigorous RCT in a population in the USA. This study may fill an important clinical gap to provide an effective medical treatment option for CP-associated pain.

Objective:

This study was conducted to evaluate the effects of nisin on in vitro fermentation, methanogenesis and functional microbial populations of the rumen.

Methods:

The negative control did not contain any additives. Monensin (5 μmol/L) was added as positive control. Nisin was added at 3 doses:3 (NI-3), 9 (NI-9), and 27 mg/100 mL (NI-27). Each treatment contained 4 replicates. Gas and methane production was measured at 0, 3, 6, 9, 12, and 24 h after incubation. Samples of culture were collected at 24 h, and used to measure rumen fermentation parameters and functional microbial populations.

Results:

Compared with negative control, both nisin and monensin addition dramatically reduced gas and methane production (P<0.05). Nisin addition had no effect on pH, dry matter degradability, and organic matter degradability (P0.05). Ammonia concentration was reduced by NI-9 (P<0.05), but was not influenced by NI-3 and NI-27 (P0.05). In contrast, monensin addition significantly lowered dry matter degradability, organic matter degradability, and ammonia concentration (P<0.05), but had no influence on pH (P0.05). Compared with negative control, both nisin and monensin addition significantly reduced acetate concentration and acetate-propionate ratio (P<0.05), and increased propionate concentration (P<0.05). Quantitative real-time PCR results showed that both nisin and monensin addition had no effects on the populations of total bacteria and Bacteroides (P0.05). Compared with negative control, the populations of protozoa, methanogens, fungi and Firmicutes were not influenced by nisin (P0.05), but were significantly reduced by monensin addition (P<0.05). Both nisin and monensin addition significantly increased the populations of sulfur-reducing bacteria and Clostridium aminophilum (P<0.05), but had no influence on the population of Clostridium sticklandii (P0.05).

Conclusion:

Appropriate nisin addition could reduce methanogenesis and ammoniagenesis, while had no adverse effect on feed digestion. These effects are probably associated with the variation of rumen functional microbial populations and communities.
