Overview
Brief Summary
This is a Phase 1, single-centre, randomised, placebo-controlled first in human study in healthy subjects. The study will assess the safety and tolerability of single-ascending (Part A) and multiple-ascending (Part B) doses of Neumifil, administered intranasally.
Detailed Description
Part A will include up to 36 healthy subjects in up to 5 groups. 6 subjects will be enrolled in Groups A1-A3 and 9 subjects will be enrolled in Groups A4 and A5. All subjects will receive a single intranasal dose of Neumifil or placebo. In Groups A1-A3, 4 subjects will receive Neumifil and 2 will receive matching placebo. In Groups A4 and A5, 6 subjects will receive Neumifil and 3 will receive matching placebo. The planned dose levels are: 0.028 mg (Group A1), 0.085 mg (Group A2), 0.28 mg (Group A3), 0.885 mg (Group A4), and 2.8 mg (Group A5). Additional dose levels may be assessed in up to 2 optional groups of up to 9 subjects each (Groups A6 and A7). Subjects will be screened within 35 days before their dose of trial medication and reside at the Investigator site from the day before their dose (Day -1) until approximately 24 hours after dosing (Day 2). They will return for a follow-up visit on Day 8-9. Part B will include up to 24 healthy subjects in up to 3 groups of 8 subjects (Groups B1-B3). Subjects will receive once-daily intranasal doses of Neumifil or placebo for 7 days. In each group, 6 subjects will receive Neumifil and 2 subjects will receive matching placebo. The starting dose level (dose and dose regimen) for Group B1 will be decided after review of safety and tolerability data from at least 3 dose levels in Part A, and will be no higher than a dose that has previously been shown to cause no safety concerns in Part A . An additional dose level may be explored in 1 optional group of up to 8 subjects (Group B4). Subjects will be screened within 35 days before their dose of trial medication and reside. at the Investigator site from the day before their first dose (Day -1) until about 24 hours after their last dose (Day 8). Subjects will attend an outpatient visit on Days 15-16. They will return for a follow-up visit on Days 21-23. During the study, dose levels for study groups will be determined by a Safety Review Committee in accordance with criteria defined in the study protocol and the Investigator site operating procedures. Dose levels will only be increased if the safety and tolerability of previous dose levels are considered to be acceptable by the Safety Review Committee.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Healthy male or female volunteer, aged 18-60 years.
- •BMI (Quetelet index) in the range 18.0-30.9 kg/m
- •Able to understand the nature of the trial and any hazards of participating in it. Ability to communicate satisfactorily with the investigator and to participate in, and comply with the requirements of, the entire trial.
- •Willingness to give written consent to participate after reading the information and consent form, and after having the opportunity to discuss the trial with the investigator or their delegate.
- •Agree to follow the contraception requirements of the trial
- •Agree not to donate blood or blood products during the study and for up to 3 months after the administration of the trial medication.
- •Spirometry readings (FEV1 and FVC) to be ≥ 80% of predicted value at the screening visit, calculated using National Health and Nutrition Examination Survey (NHANES) reference. If a subject's FEV1 or FVC is outside that range at the screening visit, the test may be repeated once on another day.
- •Registered with a General Practitioner (GP) in the UK (Part A only).
- •Willingness to give written consent to have data entered into The Overvolunteering Prevention System (TOPS).
Exclusion Criteria
- •Woman who is pregnant or lactating, or pre-menopausal woman who is sexually active and not using a reliable method of contraception.
- •Clinically relevant abnormal medical history, physical findings, ECG, or laboratory values at the pre-trial screening assessment that in the opinion of the investigator could interfere with the objectives of the trial or the safety of the volunteer.
- •Presence or history of acute or chronic illness sufficient to invalidate the volunteer's participation in the trial or make it unnecessarily hazardous.
- •Presence or history of respiratory disease, including (but not limited to) asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, emphysema, requiring acute or chronic medication.
- •Presence of nasal polyps or significant nasal abnormalities.
- •Symptoms of respiratory illness (including, but not limited to, runny nose, sore throat, sneezing, coughing or wheezing) at the screening visit or before dosing on Day
- •Tympanic temperature \> 37.5°C at the screening visit or before dosing on Day
- •Impaired endocrine, thyroid, hepatic, respiratory or renal function, diabetes mellitus, coronary heart disease, or history of any psychotic mental illness.
- •History of psychiatric disease, as determine by the investigator.
- •History or presence of malignant disease.
Arms & Interventions
Neumifil
Neumifil will be administered intranasally using an Aptar delivery system. Each dose will consist of 0.5ml to each nostril, with adjusted concentrations of solution to enable dose ranging. Participants in Part A will receive a single dose of Neumifil and participants in Part B will receive once daily doses of Neumifil for 7 days according to the randomization. Ascending single doses for Part A are anticipated to be 0.028mg (group A1), 0.085mg (group A2), 0.28mg (group A3), 0.885mg (group A4) and 2.8mg (group A5). Two further groups of up to 9 subjects may be investigated. The planned dose levels may change following review of the safety and tolerability of previous doses. The maximum dose will not exceed 2.8mg. The starting dose level (dose and dose regimen) in Part B will be determined following review of the safety and tolerability of at least 3 dose levels in part A and subsequent dose levels will be determined following review of the safety and tolerability of previous doses.
Intervention: Neumifil
Placebo
Placebo will be administered intranasally using an Aptar deliver system. Each dose will consist of 0.5ml to each nostril. Participants in Part A will receive a single dose of placebo according to the randomization and participants in Part B will receive once daily doses of placebo for 7 days according to the randomization schedule.
Intervention: Placebo
