The purpose of this study is to evaluate efficacy of ibrutinib in Japanese participants with steroid dependent/refractory chronic graft versus host disease (cGVHD) by measuring overall cGVHD response (complete response \[CR\] and partial response \[PR\] defined by National Institutes of Health \[NIH\] consensus development project criteria \[2014\]).

Overall Response Rate (ORR)
ORR is defined as the percentage of participants who achieve complete response (CR) or partial response (PR) in the absence of new therapy for chronic graft versus host disease (cGVHD) and absence of progression of underlying disease or death based on the National Institutes of Health (NIH) Consensus Development Project Criteria (2014). CR is defined as resolution of all manifestations in each organ or site; PR is defined as improvement in at least 1 organ or site without progression in any other organ or site; and chronic graft versus host disease (cGVHD) progression is defined as clinically meaningful worsening in 1 or more organs regardless of improvement in other organs.
Time frame: Up to 3 year 6 months
Sustained Response Rate
Sustained response rate was defined as percentage of participants with NIH defined CR or PR that was sustained for at least 20 weeks. CR is defined as resolution of all manifestations in each organ or site; PR is defined as improvement in at least 1 organ or site without progression in any other organ or site.
Time frame: Up to 3 year 6 months
Duration of Response (DOR)
DOR is defined as the duration from the date of initial response (CR or PR) to the date of progressive cGVHD or death, whichever occurred first. CR is defined as resolution of all manifestations in each organ or site; PR is defined as improvement in at least 1 organ or site without progression in any other organ or site; and cGVHD progression is defined as clinically meaningful worsening in 1 or more organs regardless of improvement in other organs.
Time frame: Up to 3 year 6 months
cGVHD Response Rate at Each Timepoints
cGVHD response rate was defined as percentage of participants with NIH defined CR or PR at each timepoint. CR is defined as resolution of all manifestations in each organ or site; PR is defined as improvement in at least 1 organ or site without progression in any other organ or site.

Percentage of Participants With Overall Improvement in Lee cGVHD Symptom Scale Score
Percentage of participants with overall improvement in Lee cGVHD symptom scale score was reported. Lee cGVHD symptom scale is a patient-reported symptom scale used to measure symptom burden and has 7 subscales (Skin, Eyes and Mouth, Breathing, Eating and Digestion, Muscles and Joints, Energy, and Mental and Emotional) with ratings as follows: 0-Not at all, 1-Slightly, 2-Moderately, 3-Quite a bit, 4-Extremely, with lower values representing a better outcome. A score was calculated for each subscale by taking the mean of all items completed if more than 50% were answered and normalizing to a 0 to 100 with a higher score indicating worse symptoms. An overall score was calculated as the average of these 7 subscales if at least 4 subscales had valid scores. A change of greater than or equal to (\>=) 7 points on the Lee cGVHD symptom scale overall score was considered significant and relates to improvement in quality of life (QoL).
Time frame: Up to 3 year 6 months
Number of Participants With Treatment-emergent Adverse Events (TEAEs)
An AE is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. TEAEs are adverse events with onset during the treatment phase or that were a consequence of a preexisting condition that has worsened since baseline, and occurred during treatment or within 30 days following the last dose of study treatment, or any adverse event that was considered study treatment-related regardless of the start date of the event.
