Brief Summary: This phase IbII trial studies the side effects of PLX51107 in treating steroid-refractory acute graft versus host disease GVHD PLX51107 is a novel potent non-benzodiazepine structured small molecule BET inhibitor with a unique binding mode selective for BRD4 inhibition and a more tolerable side effect profile PLX51107 may work better in treating steroid-refractory acute GVHD
Detailed Description: PRIMARY OBJECTIVES
I To evaluate the safety and tolerability of BRD4 inhibitor PLX51107 PLX51107 as a single agent for allogeneic transplant recipients with steroid-refractory acute graft versus host disease GVHD
II To assess the pharmacokinetic PK and pharmacodynamic PD of orally administered PLX51107 in steroid-refractory acute GVHD patients
SECONDARY OBJECTIVE
I To evaluate the preliminary efficacy of PLX51107 in steroid-refractory acute GVHD patients
OUTLINE
Patients receive BRD4 inhibitor PLX51107 orally PO once daily QD on days 1-28 Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity
After completion of study treatment patients are followed up at 30 days and then up to 6 months
