Reduced Intensity Regimen vs Myeloablative Regimen for Myeloid Leukemia or Myelodysplastic Syndrome (BMT CTN 0901)

Registration Number
NCT01339910
Lead Sponsor
Medical College of Wisconsin
Brief Summary

The study is designed as a Phase III, multicenter trial comparing outcomes after allogeneic hematopoietic stem cell transplantation (HCT) for acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) between patients receiving myeloablative conditioning (MAC) versus reduced intensity conditioning (RIC) regimens.

Detailed Description

Patients randomized to RIC will receive one of two regimen types: the combination of fludarabine (120-180 mg/m\^2) and busulfan (less than or equal to 8 mg/kg or IV equivalent) (Flu/Bu) or fludarabine (120-180 mg/m\^2) and melphalan (less than 150 mg/m\^2) (Flu/Mel). Patient randomized to MAC will receive one of three regimens: busulfan (16 mg/kg oral or 12.8 mg/kg IV equivalent) and cyclophosphamide (120 mg/kg) (Bu/Cy); or, busulfan (16 mg/kg PO or 12.8 mg/kg IV) and fludarabine (120-180 mg/m\^2) (Bu/Flu); or, cyclophosphamide (120 mg/kg) and total body irradiation (greater than 1200-1420cGy) (CyTBI). A total of 356 patients (178 to each arm) will be accrued on this study over a period of four years. Patients will be followed for up to 18 months from transplantation.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Overall Survival (OS)18 months post-randomization

Overall survival is defined as survival of death from any cause.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Disease Relapse18 months post-randomization

Disease Relapse is defined as relapse of the primary disease.

Percentage of Participants With Relapse-Free Survival (RFS)18 months post-randomization

Relapse-free survival is defined as survival without relapse of the primary disease.

Percentage of Participants With Treatment-related Mortality18 months post-randomization

Treatment-related mortality is defined as death without a previous relapse of the primary disease.

Number of Participants With Donor Cell EngraftmentDays 28 and 100 and 18 months post-transplant

Donor cell engraftment will be assessed by donor-recipient chimerism assays. Full donor chimerism is defined as the presence of at least 95% donor cells as a proportion of the total population in the peripheral blood or bone marrow. Graft rejection is defined as the presence of no more than 5% donor cells as a proportion of the total population. Mixed chimerism is defined as the presence of between 5% and 95% donor cells. Mixed or full donor chimerism will be considered evidence of donor engraftment.

Percentage of Participants With Acute Graft Versus Host Disease (GVHD)Day 100 post-transplant

Acute GVHD is graded according to the scoring system proposed by Przepiorka et al.1995:

Skin stage:

0: No rash

1. Rash \<25% of body surface area

2. Rash on 25-50% of body surface area

3. Rash on \> 50% of body surface area

4. Generalized erythroderma with bullous formation

Liver stage (based on bilirubin level)\*:

0: \<2 mg/dL

1. 2-3 mg/dL

2. 3.01-6 mg/dL

3. 6.01-15.0 mg/dL

4. \>15 mg/dL

GI stage\*:

0: No diarrhea or diarrhea \<500 mL/day

1. Diarrhea 500-999 mL/day or persistent nausea with histologic evidence of GVHD

2. Diarrhea 1000-1499 mL/day

3. Diarrhea \>1500 mL/day

4. Severe abdominal pain with or without ileus \* If multiple etiologies are listed for liver or GI, the organ system is downstaged by 1.

GVHD grade:

0: All organ stages 0 or GVHD not listed as an etiology I: Skin stage 1-2 and liver and GI stage 0 II: Skin stage 3 or liver or GI stage 1 III: Liver stage 2-3 or GI stage 2-4 IV: Skin or liver stage 4

Percentage of Participants With Neutrophil and Platelet EngraftmentDays 28 and 60 post-transplant

Neutrophil engraftment is defined as achieving an absolute neutrophil count greater than 500x10\^6/liter for 3 consecutive measurements on different days. The first of the 3 days will be designated the day of neutrophil engraftment. Platelet engraftment is defined as achieving platelet counts greater than 20,000/microliter for consecutive measurements over 7 days without requiring platelet transfusions. The first of the 7 days will be designated the day of platelet engraftment. Subjects must not have had platelet transfusions during the preceding 7 days.

Percentage of Participants With Chronic GVHD18 months post-transplant

Chronic GVHD is classified per 2005 NIH Consensus Criteria (Filipovich et al. 2005) into categories of severity: none, mild, moderate, and severe. Occurrence of chronic GVHD is defined as the occurrence of mild, moderate, or severe chronic GVHD per this classification.

Number of Participants With Chronic GVHD Severity18 months post-transplant

Chronic GVHD is classified per 2005 NIH Consensus Criteria (Filipovich et al. 2005) into categories of severity: none, mild, moderate, and severe.

Number of Participants With Primary Graft Failure28 days post-transplant

Primary graft failure is defined by lack of neutrophil engraftment.

Number of Participants With Secondary Graft Failure18 months post-transplant

Secondary graft failure is defined by initial neutrophil engraftment followed by subsequent decline in neutrophil counts to less than 500x10\^6/liter that is unresponsive to growth factor therapy.

Number of Participants With Maximum Grade 3-5 Toxicities18 months

The maximum grade of toxicities reported by participants over the study duration are tabulated. Per the CTCAE criteria, toxicities are graded on a scale of 0-5, with higher numbers indicating greater severity. The categories correspond as follows:

3 - severe; 4 - life-threatening; 5 - fatal

Infection Type18 months post-transplant

The number and types of infection events reported are tabulated.

Number of Participants With Infections18 months post-transplant

The maximum severity of infections reported by participants are tabulated.

The number of infections and the number of patients experiencing infections will be tabulated by type of infection, severity, and time period after transplant. The cumulative incidence of severe, life-threatening, or fatal infections will be compared between the two treatment arms at 6, 12, and 18 months from transplant or until death.

Number of Participants With Cause of Death18 months post-randomization

Primary cause of death was adjudicated using previously described criteria (Copelan et al. 2007). When relapse occurred, it was considered the primary cause of death regardless of other events.
