Clinical Trial Summary

Study Design: To evaluate the efficacy of the combination of sirolimus and tacrolimus as a graft-versus-host disease prophylaxis, the investigators are going to perform a phase II, multicenter clinical trial after human leukocyte antigen (HLA)-matched, related peripheral blood stem cell transplants (PBSCT) in patients with hematologic malignancies. Total 116 patients will be accrued.

Objective: The primary objective is to evaluate the rates of 100 day Grade II-IV acute GVHD. Secondary objectives include the time to neutrophil and platelet engraftment, the incidence of grade III-IV acute GVHD, non-relapse mortality during 100 days after transplant, mucositis severity, all infectious complications including cytomegalovirus (CMV) reactivation, vascular complications (venoocclusive disease of liver; VOD, thrombotic microangiopathy; TMA), disease-free survival, and overall survival at 1 year after transplant.

Eligibility Criteria: Eligible patients are between 20 and 60 years of age, have acute leukemia, myelodysplastic syndrome (MDS), chronic myelogenous leukemia (CML), and adequate organ function. For available sibling donor, a serologic (or higher resolution) 6/6 Class I HLA-A and B and molecular Class II DRB1 must be matched.

Treatment Description: Conditioning regimens will vary by center and donor will donate peripheral blood stem cells according to local institutional practices. Peripheral blood stem cells will not be manipulated or T-depleted prior to infusion. Tacrolimus will be administered at 0.05 mg/kg/day intravenously by continuous infusion beginning on day -1 with a target serum concentration of 5 to 10 ng/mL. Sirolimus will be administered as a 6 mg oral loading dose on day -1, followed by a 3 mg/day single dose, with a target serum concentration of 3 to 12 ng/mL. Levels will be monitored weekly during hospitalization and then as clinically indicated. Intravenous tacrolimus will be converted to an oral equivalent dose prior to discharge and both immunosuppressives will be tapered beginning at day +100 after transplantation and eliminated by day +180 when clinically feasible.

Accrual Period: The estimated accrual period is three years. Patients will be followed for 100 days post transplantation for evaluation of the primary endpoint, with additional follow-up to two years after transplantation for evaluation of secondary endpoints.


Description:

Rationale: Graft-versus-host disease (GVHD) remains a major cause of morbidity and mortality after allogeneic HSCT. The combination of a calcineurin inhibitor and methotrexate has been the standard GVHD prophylactic regimen for the past 20 years. However, the incidence of acute GVHD remains high, with reported cumulative incidence of grade II-IV up to 60%. Serious acute GVHD or chronic GVHD has detrimental consequences in patients including death, disability, infections, or prolonged hospitalization.

Sirolimus is the first available inhibitor of the mammalian target of rapamycin (mTOR). And sirolimus binds uniquely to FK-binding protein (FKBP12) and forms a complex with mTOR. This complex inhibits several biochemical pathways, resulting in a reduction in DNA transcription, DNA translation, protein synthesis, and cell cycling, ultimately leading to T-cell immunosuppression. Sirolimus has been used alone and in combination with calcineurin inhibitors for prevention of allograft rejection after solid organ transplantation. In the field of hematopoietic stem cell transplantation, the combination of sirolimus and tacrolimus has also resulted in a low incidence of acute GVHD and reduced transplant-related toxicity.

In addition, the investigators demonstrated previously that the combination of tacrolimus and sirolimus is effective as a GVHD prophylaxis and well tolerated in cases of high risk transplantation using mismatched related or unrelated donor.

As discussed above, sirolimus has emerged as one of the most promising immunosuppressive agents in allogeneic hematopoietic stem cell transplantation. However, the benefit of GVHD prophylaxis regimens including sirolimus has not been confirmed consistently and there is controversy that the incorporation of sirolimus into GVHD prophylaxis results in improved survival.

Efficacy measures: Patients will be followed for 100 days post transplantation for evaluation of the primary endpoint (the incidence and severity of acute GVHD) and clinical data will be collected at 100 day after HSCT using case report form. And patients will be recommended additional follow-up to one year after HSCT for evaluation of secondary endpoints or parameters including clinical outcomes (disease-free survival and overall at 1 year after transplant). The investigators will perform the interim analyses at the time when 31 patients are enrolled during phase 1.

Acute GVHD will be graded according to the consensus grading scale (appendix-1). The broad category of acute GVHD includes:

1. Classic acute GVHD (maculopapular rash, nausea, vomiting, anorexia, profuse diarrhea, illus, or cholestatic hepatitis) occurring within 100 days after transplantation (without diagnostic or distinctive signs of chronic GVHD)

2. Persistent, recurrent, or late acute GVHD: Features of classic acute GVHD without diagnostic or distinctive manifestations of chronic GVHD occurring beyond 100 days of transplantation (often seen after withdrawal of immune suppression).

Safety: All the safety analyses will be based on safety population. The assessment of safety will be based mainly on the frequency of adverse events and on the number of laboratory values that fall outside of predetermined ranges. Adverse events will be summarized by presenting the number and percentage of patients having any adverse event as well as by severity to study treatment. In addition the summary of grade 3 and 4 will be presented.

During administration of drugs as a GVHD prophylaxis, toxicities related to drugs will be graded according to the Common Terminology Criteria for Adverse Events (CTCAE v3.0). Patients will also be assessed regularly by physical examination and laboratory tests including CBC, biochemistry including liver function test and chest X-ray.

Statistical Methods: Descriptive statistical analysis will be performed to assess patient baseline characteristics, engraftment, acute GVHD, and non-relapse mortality. Overall survival and relapse-free survival will be calculated using the Kaplan-Meier method and estimated using a competing risk of 100-day mortality for cumulative incidence rate of grades II-IV acute GVHD.

Tacrolimus dosing is converted to oral capsules prior to discharge. Trough levels will be measured once a week. Tacrolimus will be gradually tapered beginning at day +100, and eliminated by day +180, unless the patient required continued treatment for GVHD or experienced toxicity related to drugs.
