Outcome Measures
Primary Outcomes (1)
progression-free survival (PFS)
equals date of progression/death - date of Autologous Stem Cell Transplantation
at +/- 2 weeks
Secondary Outcomes (1)
the impact of CD34+ cell dose on lymphocyte subset recovery
day 15
Study Arms (2)
3-4 x 10^6 CD34+ stem cells/kg
ACTIVE COMPARATORPatients will receive standard supportive measures (including: growth factor support post-HDT/ASCT, antimicrobial prophylaxis, red blood cell and platelet transfusion and treatment for neutropenic fever) as per institutional guideline practices.
6-8 x10^6 CD34+ stem cells/kg
EXPERIMENTALPatients will receive standard supportive measures (including: growth factor support post-HDT/ASCT, antimicrobial prophylaxis, red blood cell and platelet transfusion and treatment for neutropenic fever) as per institutional guideline practices.
Interventions
Following enrollment, patients will be CD34+ stem cell mobilized at the discretion of the treating attending physician with the plerixafor for a maximum of 4 apheresis days, for the achievement of ≥ 7 x106 CD34+ cells/kg.
Carmustine 300 mg/m2 day -6 Etoposide 100 mg/m2 q12hrs x 8 doses day - 5 thru day -2 Cytarabine 100 mg/m2 q12hrs x 8 doses day - 5 thru day -2 Melphalan 140 mg/m2 day -1 BEAM dosages may be adjusted per institutional dose adjustments based on body weight.
Eligibility Criteria
You may qualify if:
- Age ≥ 18 years old
- Diagnosed with relapsed or refractory de novo DLBCL or follicular lymphoma transformed to DLBCL to one previous line of anthracycline-containing chemotherapy
- KPS ≥ 70
- Complete or partial response by IWG Working Group or ICML Criteria to maximum of one salvage line of chemotherapy without pre-HDT/ASCT salvage radiotherapy.
- Eligible for high-dose therapy and autologous stem-cell rescue
- Serum creatinine ≤ 1.5 mg/dL, or if creatinine \>1.5 mg/dL, calculated creatinine clearance of ≥50 mL/min by 24 hour creatinine clearance or CKD-EPI.
- Last cycle of most recent salvage therapy within 8 weeks of enrollment
- Total bilirubin \< 2.0 mg/dL
- o If Gilbert"s disease is suspected and total bilirubin \> 2.0 mg/dL, direct bilirubin must be \< 2.0 mg/dL
- Females of childbearing potential and males must agree to use an acceptable form of contraception per institutional practices.
You may not qualify if:
- Disease progression by IWG Working Group or ICML Criteria since last therapy
- Prior autologous or allogeneic stem cell transplantation
- HIV infection
- Comorbid condition(s) which, in the opinion of the attending physician and/or MSKCC Principal Investigator, will preclude stem cell mobilization and/or high-dose therapy with autologous stem cell rescue
- Treatment plan that includes post-transplant maintenance therapy
- Salvage therapy that includes involved field radiotherapy
