Phase II: Overall Response Rate (ORR)Primary· Day 28
Phase II: ORR is defined as the percentage of patients demonstrating a complete response (CR) or partial response (PR) without requirement for additional systemic therapies for an earlier progression, mixed response or non-response. Scoring of response was relative to the organ stage at the start of the study treatment.
Complete response (CR) is defined as a score of 0 for the aGvHD grading in all evaluable organs that indicates complete resolution of all signs and symptoms of aGvHD in all evaluable organs without administration of additional systemic therapy for any earlier progression, mixe

Area Under the Curve (AUClast) Versus Efficacy: Impact of AUClast on Overall Response Rate (ORR) at Day 28Secondary· Day 28
To assess pharmacokinetic/pharmacodynamic relationship (comparison of AUClast with ORR at day 28). ORR is the percentage of patients with a complete response (CR) or partial response (PR) without additional systemic therapies. Given age group did not have a significant effect on the model fit, the comparison is made indirectly through the odds ratio across exposure levels in each group. A high response rate may prevent model convergence. Results are shown only upon successful convergence.

The study was an open-label, single-arm, Phase I/II multi-center study to investigate the PK, activity and safety of ruxolitinib added to the patient's immunosuppressive regimen in infants, children, and adolescents ages ≥28 days to \<18 years old with either grade II-IV aGvHD or grade II-IV SR-aGvHD. The trial design included four age groups: Group 1 included patients ≥12y to \<18y, Group 2 included patients ≥6y to \<12y, Group 3 included patients ≥2y to \<6y, and Group 4 included patients ≥28days to \<2y.
