Summary

This is a single-arm, phase I/II, study of PTCy/sirolimus plus VIC-1911 to prevent GVHD and relapse after Allogeneic Hematopoietic Cell Transplantation (alloHCT).

Detailed description

Determination of the optimal dose during the Phase I trial is based on Dose Limiting Toxicity for safety and reduction of CD4+, pH3ser10+ T cells (phosphorylated histone 3 serine 10 is a biomarker of Aurora kinase A activity) for efficacy. Phase II will be powered to improve grade III-IV acute graft-versus-host disease and relapse after alloHCT, compared to historical estimates at the University of Minnesota. Patients will receive myeloablative conditioning (MAC) with total body irradiation (TBI) followed by infusion of HLA-matched related or unrelated peripheral blood stem cells (PBSC) on day 0. Cyclophosphamide will be administered on days +3 and +4. Sirolimus targeting 8-12ng/ml will begin on day +5 until day +365. VIC-1911 will be administered as 25 mg, 50 mg, or 75 mg orally BID from day +5 to day +45 according to the rules of our phase I study. The lowest biologically active and safe dose of VIC-1911 will be identified as the recommended phase II dose.
