aGVHD

The purpose of this study is to see if see if adding the specific combination of donors can result in acceptable levels of survival without evidence of disease.

To apply Ivarmacitinib for the prevention of acute graft-versus-host disease (aGVHD) in HLA haploidentical transplantation, the incidence of grade II-IV aGVHD after prevention, the incidence of primary graft failure, the rate of GVHD-free relapse-free survival (GRFS) (12 months), the incidence of infection, the incidence of chronic graft-versus-host disease (cGvHD) (100 days - 1 year), treatment-related mortality, the incidence and severity of cytokine release syndrome (CRS), and the safety of the prevention regimen will be evaluated.

A Phase IIb open label study evaluates the safety and efficacy of repeat doses of BPC2001 in combination with standard of care treatment for the prevention of acute graft-vs-host-disease (aGvHD) in subjects following Haploidentical Stem Cell Transplantation (Haplo-SCT).

This trial employs a single-arm, single-center design, planning to enroll 25 patients diagnosed with grade II-IV aGVHD at one center. Patients meeting all inclusion criteria and no exclusion criteria will be enrolled. After enrollment, all patients will receive Gecacitinib combined with methylprednisolone sodium succinate for at least 28 days. After 28 days of Gecacitinib treatment, patients evaluated by the investigator as achieving Complete Response (CR) or Partial Response (PR) may continue study treatment for up to 24 weeks. If patients experience intolerance, disease progression, or require new systemic therapy, treatment will be adjusted.
