Screening details |
This study was designed to evaluate parsaclisib 2.5 mg QD compared with placebo over a 24-week double-blind treatment period followed by a 24-week open-label treatment period with parsaclisib. Participants could then continue to receive parsaclisib in a long-term extension period. | ||||||||||||||||||||||||

A durable hemoglobin response was defined as hemoglobin ≥10 grams per deciliter (g/dL) with an increase from Baseline of ≥2 g/dL not attributed to rescue therapy at ≥3 of the 4 available visits at Week 12 and/or later during the 24-week double-blind treatment period. Analysis was conducted in members of the Safety Analysis Set, comprised of all randomized participants who received at least 1 dose of study drug. Treatment groups were determined according to the actual treatment the participant received on Day 1 regardless of assigned study treatment.

End point description |
The FACIT-F scale was developed to assess anemia-related fatigue. The FACIT-F is a 13-item measure that assesses self-reported fatigue and its impact upon daily activities and function over the past 7 days. A clinically meaningful change in the FACIT-F score was defined as ≥3-point increase from Baseline. Item scores range from 0 (“not at all”) to 4 (“very much”), and the total score ranges from 0 to 52; lower scores indicate greater fatigue. Change from Baseline was calculated as the post-Baseline value minus the Baseline value.

End point description |
A new or increased dose of corticosteroids (prednisone or equivalent) from the Day 1 dose was permitted as rescue treatment. Rescue medication was to be considered if the absolute hemoglobin level continued to decline, there was a > 1 g/dL decrease in hemoglobin from the prior assessment, or the participant developed new or worsening symptoms of wAIHA. Percentage change from Baseline was calculated as ([the post-Baseline value minus the Baseline value]/Baseline value) x 100. As pre-specified in the Statistical Analysis Plan, with limited participants enrolled in each treatment group, as well as the option for early transition to open-label parsaclisib, the statistical analyses, as related to efficacy and defined by the Protocol, are not applicable. Thus, data analysis was not performed for this outcome measure.

End point description |
An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it was considered drug-related. An AE could therefore be any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study drug. TEAEs were defined as AEs reported for the first time or the worsening of pre-existing events after the first dose of study drug.

End point description |
An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it was considered drug-related. TEAEs were defined as AEs reported for the first time or the worsening of pre-existing events after the first dose of study drug. The severity of AEs were assessed using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 Grades 1 through 5. 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.

Adverse event reporting additional description |
For safety analysis, participants who transitioned from treatment with placebo to treatment with parsaclisib 2.5 milligrams (mg) once daily (QD) in the the open-label treatment period and the long-term extension period have been counted both in the placebo arm and the parsaclisib arm.
