E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the effect of ACT-129968 vs. placebo on forced expiratory volume, measured in 1 second (FEV1) during the late allergic reaction (3–10 hours) after a bronchial allergen challenge. |
|
E.2.2 | Secondary objectives of the trial |
• To investigate the effect of ACT-129968 on airway inflammation and airway hyperresponsiveness (AHR) after a bronchial allergen challenge. • To investigate the tolerability and safety of ACT-129968. • To investigate the pharmacokinetics (PK) of ACT-129968 in subjects with mild to moderate allergic asthma.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
•Men and women not of childbearing potential 18–55 years of age (inclusive). -Women not of childbearing potential are defined as postmenopausal (i.e., amenorrhea for at least 1 year), or surgically or naturally sterile. •Signed informed consent prior to any study-mandated procedure. •Having stable, mild to moderate allergic asthma for at least 1 year and fulfilling all of the following criteria at screening (all assessments should be performed within a period of 1 week): –No ongoing or recent treatment (see definition below) for allergic airway disease (prescribed or over-the-counter [OTC]) other than stable use of short-acting, inhaled beta2 agonist as needed. –Asymptomatic hay fever at screening, which is expected to remain asymptomatic during the study. –No hospital admissions for asthma in the previous year. –FEV1 >= 70% of predicted value at both of the screening visits, measured >= 8h after any use of a short-acting inhaled beta2 agonist. –Airway hyperresponsiveness to inhaled methacholine (Mch) with the provocative concentration of Mch causing a fall in baseline FEV1 of 20% (PC20FEV1) (Mch) < 16 mg/mL Mch chloride. –Early and late allergic reaction (EAR, LAR) airway response with >= 15% minimal reduction in FEV1 during LAR (3–10h) following a standardized bronchial allergen challenge with house dust mite (HDM) extract. • Positive skin prick test (wheal diameter >= 3 mm) to HDM extract within 1 year before screening. • Body mass index (BMI) between 18 and 33 kg/m2 (inclusive) at screening. • Systolic blood pressure (SBP): 100–150 mmHg, diastolic blood pressure (DBP): 50–90 mmHg and heart rate (HR): 40–90 bpm (all inclusive) after 5 minutes in the supine position at screening. • 12-lead electrocardiogram (ECG) without clinically relevant abnormalities at screening. • Hematology, biochemistry, and urinalysis test results not deviating from the normal range to a clinically relevant extent at screening. • Negative results from drug screen (amphetamines, cocaine, cannabinoids, opiates, benzodiazepines, cotinine) at screening. • Ability to communicate well with the investigator in the local language and to understand and comply with the requirements of the study.

E.4 | Principal exclusion criteria |
• Ongoing or recent (see below) treatment with medications for allergic airway disease (either prescribed or OTC) other than short-acting, inhaled beta2 agonist. • Recent treatment for the following medications is defined as: – Systemic corticosteroids: within 8 weeks prior to screening. – Inhaled corticosteroids: within 4 weeks prior to screening. – Intranasal corticosteroids: within 4 weeks prior to screening. – Leukotriene receptor antagonists: within 2 weeks prior to screening. – Cromoglycate: within 2 weeks prior to screening. – Theophylline: within 1 week prior to screening. – Anti-histamines: within 1 week prior to screening. – Long-acting beta2 agonists: within 1 week prior to screening. – Anti-cholinergics: within 1 week prior to screening. – Anti-immunoglobulin E (IgE): within 6 months prior to screening. – Immunotherapy: any previous use. – Other medications: at the discretion of the investigator and with the sponsor’s consent. • Smoking within the last year or life-time consumption > 10 pack-years • Symptoms of a clinically relevant lower respiratory tract infection in the 3-week period prior to screening. • Diagnosis of aspirin or non-steroidal anti-inflammatory drug (NSAID)-induced asthma. • Planned treatment or treatment with another investigational drug within 3 months prior to screening. • Loss of 250 mL or more of blood within 3 months before the screening examination. • Positive HIV serology. • History of hepatitis B or C and/or positive hepatitis serology, indicating acute or chronic hepatitis B or C. • History or clinical evidence of alcoholism or drug abuse within the 3-year period prior to the screening examination. • History or clinical evidence of any disease and/or existence of any surgical or medical condition which might interfere with treatment compliance, study conduct or interpretation, such as any unstable medical abnormality or a disease which could affect the absorption, distribution, metabolism, or excretion of the study drug. • Known hypersensitivity to any excipients of the study drug formulation. • Any clinically relevant drug or food allergy. • Legal incapacity or limited legal capacity at screening.
