Registered outcomes9

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryEffect of PBF-680 on trough forced expiratory volume in 1 second (FEV1)16 DaysDefined as the average of the FEV1 measurements taken at 23h 15min and 23h 45min post-dose after the final dose.
SecondaryEffect of PBF-680 in the FEV1 area under curve AUC30min-23h 30min post-dose16 daysDefined as the FEV1 area under curve of a serial of spirometries from 30min-23h 30min post-dose through days 15-to-16
SecondaryEffect of PBF-680 in the standardized FEV1 AUC30min-6h post- dose15 DaysDefined as the FEV1 area under curve of a serial of spirometries from 30min-6h post-dose on day 15
SecondaryEffect of PBF-680 in the pre-bronchodilator FEV18 daysDefined as the FEV1 before use of bronchodilator at pre-dose spirometry on day 8
SecondaryEffect of PBF-680 in the post- bronchodilator FEV1 at pre-dose spirometry on day 8Day 8 and Day 16Defined as the FEV1 after use of bronchodilator at pre-dose spirometry on day 8 and 16
SecondaryEffect of PBF-680 on the asthma control as measured by Asthma QuestionnairesDay 8 and Day 15
Asthma Control Questionnaire (ACQ-7) comprises 5 patient-reported symptoms that are scored from 0 to 6.The points are added and divided by 5. According to the result: Less than or equal to 0.75: Adequate control of asthma From 0.75 to 1.50: partially controlled asthma More than 1.50: Inadequate control of asthma. The Asthma Quality of Life Questionnaire AQLQ(S) scores symptoms, activity limitation, emotional function, and environmental exposure through 32 questions. The overall AQLQ score is the mean of the responses to each-of the 32 questions on a 7- point scale (7=no impairment, 1 =severe impairment)
SecondaryEffect of PBF-680 on daily, morning and evening FEV1 and PEF as measured by an electronic diary/Peak Expiratory Flow (PEF) meter device.16 daysOn each morning and evening, the subjects must fill the diary questions and record three brief expiratory maneuvers that generate PEF and FEV1 data.
SecondaryEffect of PBF-680 in the use of rescue bronchodilator as reported by the subject using an electronic diary/PEF meter device.16 daysOn each morning and evening, the subjects must fill the diary questions and record three brief expiratory maneuvers that generate PEF and FEV1 data
SecondaryNumber of subjects with treatment-related adverse events as assessed by CTCAE v416 daysAdverse events will be assessed according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4
