A Single-arm Trial of Prophylactic Tocilizumab for Acute GVHD Prevention After Haploidentical HSCT.

Registration Number
NCT04688021
Lead Sponsor
Yi Luo
Brief Summary

A single-arm trial using Tocilizumab for acute GVHD prophylaxis after haploidentical HSCT.

Detailed Description

This study will enroll haploidentical HSCT patients with high risk for acute GVHD. Tocilizumab (8mg/kg) will be added to the conventional acute GVHD prophylaxis regime (CsA+Methotrexate(MTX)+low dose mycophenolate mofetil(MMF)+ATG) on day -1 of transplant. The previous patients will be used as control.

Primary Outcome Measures
NameTimeMethod
Cumulative incidence of grade II-IV acute graft-versus-host disease100 days

Date of symptom onset, maximum clinical grade, and dates and types of treatment will be recorded. Dates of symptom onset of grade II-IV acute graft-versus-host disease (aGVHD) will be recorded. The aGVHD score of each affected organ will be recorded.

Cumulative incidence of non grade II-IV acute graft-versus-host disease survival100 days

All patients will be tracked from Day 0 to date of grade II-IV acute graft-versus-host disease (aGVHD) onset. Patients who did not present grade II-IV aGVHD or died will be censored at the last date they were assessed and deemed free of grade II-IV aGVHD.

Secondary Outcome Measures
NameTimeMethod
Cumulative incidence of engraftment100 days

All patients will be tracked from Day 0 to date of myeloid and platelet engraftments, respectively.

Cumulative incidence of infections2 years

All patients will be tracked from Day 0 to date of infection diagnosis as proved by relevant standard diagnostic criteria.

Overall survival (OS)2 years

All patients will be tracked from Day 0 to date of first objective disease progression, death from any cause, or last patient evaluation. Patients who have not progressed or died will be censored at the last date they were assessed and deemed free of relapse or progression.

Progression-free survival (PFS)2 years

All patients will be tracked from Day 0 to date of first objective disease progression, death from any cause, or last patient evaluation. Patients who have not progressed or died will be censored at the last date they were assessed and deemed free of relapse or progression.

Cumulative incidence of transplant-related nonrelapse mortality (NRM)2 years

All patients will be tracked from Day 0 to date of first objective disease progression, death from any cause, or last patient evaluation. Patients who have not progressed or died will be censored at the last date they were assessed and deemed free of relapse or progression.

Cumulative incidence of disease relapse or progression2 years

All patients will be tracked from Day 0 to date of first objective disease progression, death from any cause, or last patient evaluation. Patients who have not progressed or died will be censored at the last date they were assessed and deemed free of relapse or progression.
