PRIMARY outcome

Timeframe: Start of treatment through Week 4 of treatment

Population: 0 patients analyzed. 1 patient withdrawn early and 1 patient not complaint with study procedures.

During dose escalation, subjects will be assessed for dose-limiting toxicities at each dose level.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 6 weeks, 3 months, and 6 months after initiation of treatment

Population: Subject 1 off study before 6 week assessment due to study drug possibly related rash SAE.

Response rate of clinically significant GVHD will be assessed using NIH criteria (from 2014 NIH Consensus Development Project).

Timeframe: 6 weeks, 3 months, and 6 months after initiation of treatment

Population: Laboratory correlates for this study were not processed or analyzed for any subject enrolled onto this study.

Plasma ST2 and CD4CD25FOXp3 correlates will be measured at identified intervals to determine if either correlate demonstrates an affect on clinical response.

Rituximab \*375 milligrams (mg) per meter squared intravenous infusion weekly for 4 (may repeat 8 weeks after initial therapy, if suboptimal response) Ibrutinib * 420 mg (140 mg capsule x3) by mouth daily * May be given beyond 3-6 months (for maintenance). Ibrutinib: Subjects will receive oral (PO) Ibrutinib 140 mg once daily with Rituximab 375 mg per meter squared IV weekly x4 (with pre-medications and infusion procedure as per standard protocol) Rituximab Pre-medications:Acetaminophen 650 mg PO; Diphenhydramine 25 mg PO/IV; Dexamethasone 20 mg IV. If no adverse events \>Grade 3+ are noted after 1 week, the Ibrutinib dose schedule will be increased to 280 mg daily. If no adverse events \>Gr3+ are noted after an additional 1 week, the Ibrutinib dose will be increased to 420 mg daily. Rituximab: Subject will receive an intravenous infusion of 375mg per meter squared weekly for 4 weeks, which may be repeated 8 weeks after initial therapy if only a suboptimal response is achieved.
