Immunological Effects From Intranasal Chitin Micro-Particles (INCA)
|ClinicalTrials.gov Identifier: NCT01508039|
Recruitment Status : Completed
First Posted : January 11, 2012
Last Update Posted : January 26, 2012
The purpose of the study is:
- To investigate whether chitin can effect healthy adults, the nasal mucosa in a direction that will enhance the immune response to infection
- To investigate whether chitin influence of the nasal mucosa is well tolerated, and that there is no inflammation, as it seen with exposure to endotoxin.

Experimental: Treatment with chitin micro-particles
The study will involve 14-healthy subjects confirming to the inclusion criteria randomised to the treatments.
Other: Chitin Micro Particle
The total spray volume for each application is 0.4 ml equivalent to a total single-dose for chitin of 2 mg (0.5 mg per 0.1 ml spray).
A total single-dose for LPS, of 2 mg of endotoxin from Enterobacter agglomerans (0.5 mg per 0.1 ml spray)
Other Name: Chitin micro-particle
- Changes in levels of cytokines in nasal lavage fluid compared with dosing with placebo. [ Time Frame: Period 1, day 0. Period 2, day 14 ]Change in levels of cytokines (TNF-alfa, IFN-gamma, IL-1b, IL-4 IL5, IL, 6, IL-8, IL-10 and IL-13) in nasal lavage fluid compared to dosing with placebo.
- Changes in levels of cytokines in nasal lavage fluid compared with dosing with active control. [ Time Frame: Day0, day 14,day 28. ]Changes in levels (maximum concentration) of TNF-alfa, IFN-gamma, IL-1b, IL-4, IL5, IL-6, IL-8, IL-10 and IL-13 in nasal lavage samples following intranasal dosing with cmp compared to lipopolysaccharide active control.
- Change from baseline. [ Time Frame: Day 0, day 14, day 28 ]
The total eosinophil counts and cysteinyl leukotriene concentration in nasal lavage fluid following intranasal dosing with cmp.
Total nasal symptom scores at 4 and 8-hours following intranasal dosing with cmp.
- Safety check. [ Time Frame: Day0, day14, day 28. ]Safety will be assessed using the adverse events, vital signs and nasal acoustic rhinometry following dosing with cmp versus placebo.
