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.
Other: Chitin Micro Particle
||Intervention Model: Single Group Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
||A Randomised, Double-blind,Single-dose,Placebo and Single-blind Active Controlled Cross-over Study in Healthy Volunteers to Access in Effects of Intranasal Chitin Micro-particles on the Release of Cytokines From Nasal Mucosa
Primary Outcome Measures:
- 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.
Secondary Outcome Measures:
- 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.

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
|Ages Eligible for Study:
||18 Years to 30 Years (Adult)
|Sexes Eligible for Study:
|Accepts Healthy Volunteers:
• healthy non-smoking male or female volunteers between 18 and 30 years of age, inclusive (at screening).
- asymptomatic at screening as characterized by normal appearing nasal mucosa with no active allergic rhinitis.
- be free from clinically significant cardiac, pulmonary, gastrointestinal, hepatic, neurological and psychiatric disease as determined by medical history, physical examination and screening investigations.
- with no clinically-significant deviation outside the normal ranges for blood pressure and pulse measurements.
- capable of giving informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
- be available to complete the study.
- satisfy a medical examiner about their fitness to participate in the study.
- provide oral and written informed consent to participate in the study.
- perennial rhinitis.
- upper respiratory tract infection within 2 weeks of the first dose of study medication.
- medical conditions likely to affect the outcome of the study in the opinion of the investigator.
- nasal conditions likely to affect the outcome of the study in the opinion of the investigator, i.e. nasal septal perforations, nasal polyps, sinus disease, chronic nasal obstruction, or other nasal diseases.
- presence of any respiratory disease other than a history of mild stable asthma not requiring treatment and associated with normal lung function (defined as ≥ 80% predicted for height and age, "Danish Society of Lung Physicians 1986").
- a history of immunotherapy in the past 3 years or currently on an immunotherapy treatment course including inhaled or local corticosteroids in the past 28 days.
- any infirmity, disability, or geographic location which, in the opinion of the chief investigator, would limit compliance with the protocol.
- infection of the upper airways/lower airways, sinus, or ear, including viral infections in the 14 days prior to screening and at the start of/or during the treatment period.
- subjects with inability to tolerate lavage correctly with a preliminary nasal lavage at screening.
- participation in a study with a new molecular entity during the previous four months or any other trial during the previous three months.
- regularly, or on average, drink more than four units of alcohol per day.
- are in receipt of prescribed or over the counter medication (including herbal remedies and dietary supplements) within 14 days of the first dose of test article and for the duration of the trial (with the exception of paracetamol up to 2g daily). In particular, all antihistamines, chromoglycate and steroids are prohibited during this period.
- inability to communicate well with the investigator (i.e., language problem, poor mental development or impaired cerebral function).
- have donated 450 mL or more blood within the previous 12 weeks.
- clinical features suspicious of tuberculosis - weight loss, haemoptysis pyrexia, purulent sputum, previous abnormal chest X-ray will be excluded from the study.
- clinical evidence of autoimmune disease.
- with allergy to seafood or any of the excipients in the study drug formulation.
