Lead Sponsor:
Ablynx, a Sanofi company
Conditions:
Respiratory Syncytial Virus Infection
Eligibility:
All Genders
18-60 years
Phase:
PHASE1
Brief Summary
This is a Phase I, single-centre, open label study to evaluate the occurrence and subsequent reversibility and prevention, of bronchoconstriction following single and repeated oral inhalations of ALX-...
Eligibility Criteria
Inclusion
- Adult male and female subjects aged 18-60 years (both included).
- Subjects must demonstrate a PC20 (concentration of the agonist in the inhaled substance leading to a fall in FEV1 of ≥20.0% of personal best at same visit) response to methacholine (MCh) concentrations of \> 1 mg/mL and ≤ 8 mg/mL at screening.
- Subjects not on concomitant treatments except for
- medication that has no effect on hyperresponsiveness, bronchoconstriction or on lung function parameters
- respiratory medication for which subjects are able to discontinue their current treatment during the study period taking into account the respective wash-out periods as listed in the protocol.
- short-acting bronchodilators under certain conditions as specified in the protocol.
- Screening forced expiratory volume (FEV1) value of \> 60.0% of the predicted normal value after a wash-out of respiratory medication as listed in the protocol.
- Subject has been informed both verbally and in writing about the objectives of the clinical trial, the methods, the anticipated benefits and potential risks and the discomfort to which he may be exposed, and has given written consent to participation in the trial prior to trial start and any trial-related procedure.
- Body weight according to a Body Mass Index ≥ 18.5 and ≤ 29.0 kg/m².
- Non-smokers or ex-smokers who have stopped smoking for at least 1 year prior to start of the clinical study. No history of smoking more than 10 pack years.
- Ability to inhale in an appropriate manner.
- Female subjects of childbearing potential and male subjects must agree to use appropriate methods of contraception as specified in the protocol.
Exclusion
- Subjects with a pre-dose baseline FEV1 measurement on the first day (i.e. prior to the first inhalation of ALX-0171 placebo) which is below or equal to 60.0% of the predicted FEV1 value.
- Presence of clinically significant diseases other than asthma, hyperresponsive airways or atopic diseases (cardiovascular, renal, hepatic, gastrointestinal, haematological, neurological, genitourinary, autoimmune, endocrine, metabolic, etc.), which, in the opinion of the investigator, may either put the subject at risk because of participation in the trial, or diseases which may influence the results of the study or the subject's ability to take part in it.
- Presence of relevant pulmonary diseases (except asthma) or history of thoracic surgery.
- History or current evidence of clinically relevant allergies to drugs.
- Any absolute or relative contraindications for methacholine challenge: e.g., severe or moderate airflow limitation (FEV1 ≤ 60.0% predicted or \< 1.5 L), heart attack or stroke in the last 3 months, uncontrolled hypertension, known aortic aneurysm, current use of cholinesterase inhibitor medication.
- Hospitalisation or emergency room treatment for acute asthma in the 3 months prior to screening, between screening and the start of the treatment period.
- Hospitalisation for longer than 24 hours for the management of an asthma exacerbation within the preceding 3 months of the screening visit or intubation (ever) for that named cause.
- History of allergic reactions to any active or inactive ingredients of the nebuliser solution.
- ECG abnormalities of clinical relevance.
- Clinically relevant abnormal heart rate and/or blood pressure as judged by the investigator.
- Proneness to orthostatic dysregulation, fainting, or blackouts.
- History (within the last 5 years) or presence of any malignancy except for basalioma.
- Clinically relevant abnormalities in clinical chemical, haematological or in any other laboratory variables.
- Chronic or clinically relevant acute infections.
- Clinically relevant positive results in any of the following virology tests: Hepatitis B surface antigen, Hepatitis C antibodies, human immunodeficiency virus (HIV)-1, and HIV -2 antibodies.
- Positive drug screen.
- History of previous administration of ALX-0171 or any other medication targeting the F-protein (e.g. palivizumab) or any other inhaled biologic. In any other case of use of biologics: 6 months, or the time of duration of the pharmacodynamic effect, or 10 times the half-life of the respective drug, whatever is longer, before first trial medication administration.
- History or presence of alcohol or drug abuse.
- Planned donation of germ cells, blood, organs, bone marrow during the course of the trial or within 6 months thereafter.
- Participation in another clinical trial with an investigational drug within the last month (defined as 1 month between last visit previous trial and Informed Consent Form (ICF)signature of the current trial).
- Blood donation within the last 30 days before screening.
- Lack of ability or willingness to give informed consent.
- Anticipated non-availability for trial visits/procedures.
- Anticipated lack of willingness or inability to cooperate adequately.
- Vulnerable subjects (e.g., persons kept in detention).
- Consumption of any xanthine derivates (such as -but not limited to-, caffeine, theophylline, chocolate) 6 hours before first procedure at each study visit.
- Pregnant or lactating women.
