What was measured

BOR was defined as the percentage of participants who achieved an overall response (CR+PR) based on cGvHD disease assessments (National Institutes of Health Consensus Criteria) without the requirement of additional systemic therapies for an earlier progression, mixed response, or non-response at any time point (up to Cycle 7 Day 1 or the start of additional systemic therapy for cGvHD). Scoring of response was relative to the organ score at the time of randomization. CR: complete resolution of all signs and symptoms of cGVHD in all evaluable organs without the initiation or addition of new systemic therapy. PR: improvement in at least one organ (e.g., improvement of 1 or more points on a 4- to 7-point scale, or an improvement of 2 or more points on a 10- to 12-point scale) without progression in other organs or sites, initiation, or addition of new systemic therapies. This analysis was based on the primary cutoff date (May 2020).

Analysis population: FAS. Data reported are from the start of the study to Cycle 7 Day 1 (data cutoff of 08 May 2020).

Groups in this outcome

Ruxolitinib

Ruxolitinib was administered orally twice per day at a dose of 10 milligrams (mg).

Best Available Therapy

Participants received best available therapies (BATs), including, but not limited to, extracorporeal photopheresis (ECP), low-dose methotrexate (MTX), mycophenolate mofetil (MMF), mTOR inhibitors (everolimus or sirolimus), infliximab, rituximab, pentostatin, imatinib, and ibrutinib based on the investigator's decision.
