Summary

This study aims to evaluate the optimal dose (Recommended Phase 2 Dose, RP2D), preliminary safety, and efficacy of gecacitinib (also known as jaktinib) in combination with glucocorticoids as first-line therapy for patients with grade II-IV acute graft-versus-host disease (aGVHD) following allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Conditions

  • Acute Graft Versus Host Disease

Interventions

DRUG

Gecacitinib (also known as Jaktinib) combined glucocorticoids

This clinical trial employs a standard 3+3 design to establish the Recommended Phase 2 Dose (RP2D) of gecacitinib (also known as jaktinib) combined with methylprednisolone. The dose escalation begins at 50 mg QD. Based on the safety observed in the initial cohort of three subjects, the dose will either be escalated to 50 mg BID or the cohort will be expanded. The subsequent escalation level is to 150 mg QD. Throughout this phase, the methylprednisolone dose is adjusted per the investigator's assessment. After determining the RP2D, the study advances to an efficacy evaluation stage, where approximately 25 additional subjects are enrolled to receive the combination at the RP2D for a minimum of 28 days. The primary objective of the initial phase is to assess safety and tolerability, while the secondary goal of the expansion is to gather preliminary efficacy data on the combination regimen.
