E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the safety of nebulised RPL554 at 2 single inhaled doses of 0.036 mg/kg (12X) and 0.072 mg/kg (24X) in allergic asthmatics using standard safety measures with intensive monitoring of any potential cardiovascular effects. |
|
E.2.2 | Secondary objectives of the trial |
1) To investigate the onset, magnitude and duration of RPL554’s bronchodilator effects in terms of maximal increase from baseline (pre-bronchodilator) Forced Expiratory Volume in the first second (FEV1) and the duration of the bronchodilator response (in FEV1) over time. 2) To investigate RPL554’s pharmacokinetics including the relationship between pharmacokinetics and bronchodilation; and the relationship between pharmacokinetics and any adverse events observed over time.

E.5 End points |
E.5.1 | Primary end point(s) |
A)Respiratory safety (i.e., effects on the upper and lower airways): -upper airways (nose): local irritation, sneezing, prolonged rhinorrhea, nasal congestion; -throat: local irritation, redness, dryness, effect on the voice; -lower airways (lung): coughing, dyspnoea/wheeze, clinically relevant decreases in breathing frequency and/or peripheral oxygen saturation (measured by pulse-oximetry during nebulisation) and/or decreases in spirometry (FEV1). B) Gastrointestinal safety/tolerability (i.e., nausea, vomiting, and abdominal discomfort or pain and/or diarrhoea). C) Cardiovascular safety (i.e., clinically relevant effects on heart rate & rhythm, and conduction times; and sitting blood pressure (also see relevant section 6.1.1 on cardiovascular safety) -12-lead ECG and holter ECG (rhythm and conduction times- with particular care given to the QTc interval) at baseline, during dosing and at regular intervals up to approximately 12 h; -ECG telemetry during nebulisation up to approximately 2 h post-dosing; -Sitting blood pressure and heart rate at baseline and at regular intervals (approximately 5-10 min) during nebulisation up to 1 h post-dosing and subsequently at approximately 15 min intervals up to 4 h post-dosing, followed by hourly intervals to 12 hours, and at approximately 24 h; Additional standing blood pressure measurements (within 2 minutes of sitting blood pressure measurements) will be collected at 15 min, 45 min and 2 h post-dosing for 12X dose and at 30 min, 60 min, and 2 h post-dosing for 24X dose. D) Blood chemistry safety by standard clinical assessment at baseline and at 24 h post-dosing E) Full hematological assessment (i.e., cell counts and coagulation status) at baseline, and at approximately 35 min and 24 h post-dosing. F) Symptoms and any adverse events throughout the study G) Subjective tolerability (i.e., taste, aftertaste, and smell as well as nasal irritation) throughout the study |
