ListOutcomeTime frameDescription
PrimaryNumber of Participants With Any Treatment-emergent Adverse Event (TEAE)up to approximately 162 weeks
An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug-related. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. A TEAE was defined as either an AE reported for the first time or the worsening of a pre-existing condition after the first dose of itacitinib until 30 days after the last dose of itacitinib.
PrimaryNumber of Participants With Any Grade 3 or Higher TEAEup to approximately 162 weeks
An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug-related. A TEAE was defined as either an AE reported for the first time or the worsening of a pre-existing condition after the first dose of itacitinib until 30 days after the last dose of itacitinib. The severity of AEs was assessed using Common Terminology Criteria for Adverse Events v5.0. Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; treatment not indicated. Grade 2: moderate; minimal, local, or noninvasive treatment indicated; limiting age appropriate activities of daily living. Grade 3: severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living. Grade 4: life-threatening consequences; urgent treatment indicated. Grade 5: fatal.
PrimaryChange From Baseline in Forced Expiratory Volume in 1 Second (FEV1) at Week 12Baseline; Week 12FEV1 was defined as the volume of air exhaled in 1 second. Change from Baseline was calculated as the post-Baseline value minus the Baseline value.
PrimaryPhase 2: FEV1 Response RateBaseline through Week 12
FEV1 response rate was defined as the percentage of participants demonstrating a ≥10% absolute increase in FEV1 compared with Baseline, confirmed by 2 consecutive spirometric assessments ≥1 week apart.
SecondaryPhase 1: Duration of FEV1 Responseup to 34.9 months
Duration of FEV1 response was defined as the interval between the onset of response and the earliest of bronchiolitis obliterans syndrome (BOS) progression, loss of clinical benefit as determined by the investigator, or death.
SecondaryPhase 2: Duration of FEV1 Responseup to 24 months
Duration of FEV1 response was defined as the interval between the onset of response and the earliest of bronchiolitis obliterans syndrome progression, loss of clinical benefit as determined by the investigator, or death.
SecondaryPhase 1: Time to Progressionup to 36.4 months
Time to progression was defined as defined as the interval between the start of treatment and bronchiolitis obliterans syndrome progression (≥10% absolute decrease in FEV1 compared to baseline), or death.
SecondaryPhase 2: Time to Progressionup to 24 months
Time to progression was defined as defined as the interval between the start of treatment and bronchiolitis obliterans syndrome progression (≥10% absolute decrease in FEV1 compared to baseline), or death.
SecondaryPhase 1: Change From Baseline in the St. George's Respiratory Questionnaire (SGRQ) Total ScoreBaseline; up to 158.4 weeks
The SGRQ is a disease-specific instrument designed to measure the impact on overall health, daily life, and perceived well-being in participants with obstructive airway disease. It consists of 50 items covering 3 domains: symptoms (8 items), activity (16 items), and impacts (26 items). A component score is calculated for each of the 3 domains. One total score is calculated if none of the component scores is missing. All scales (both domain and total) have a score ranging between 0 and 100, with higher scores indicating a worse quality of life. Change from (CFB) Baseline was calculated as the post-Baseline value minus the Baseline value.
SecondaryPhase 2: Change From Baseline in the SGRQ Total Scoreup to 24 months
The SGRQ is a disease-specific instrument designed to measure the impact on overall health, daily life, and perceived well-being in participants with obstructive airway disease. It consists of 50 items covering 3 domains: symptoms (8 items), activity (16 items), and impacts (26 items). A component score is calculated for each of the 3 domains. One total score is calculated if none of the component scores is missing. All scales (both domain and total) have a score ranging between 0 and 100, with higher scores indicating a worse quality of life. Change from Baseline was to be calculated as the post-Baseline value minus the Baseline value.
