About

The purpose of this study is to find out what effects, good and/or bad, the treatment including 1) Lenalidomide-RCHOP, 2) R-HIDAC, and 3) Lenalidomide-Rituximab maintenance has on the participant and their lymphoma.

Full description

Patients will receive lenalidomide 15 mg orally daily on days 1-14 with standard-dose R-CHOP (375 mg/m^2 intravenous rituximab, 750 mg/m2 intravenous cyclophosphamide, 50 mg/m^2 intravenous doxorubicin, and 1.4 mg/m2 intravenous vincristine on day 1, and 100 mg prednisone days 1-5 or days 2-6) every 21 days for four cycles.

All patients will receive pegfilgrastim on day 2 of each cycle and aspirin 81 mg orally daily for venous thromboembolism prophylaxis throughout the four cycles.

After four cycles of Len-RCHOP, the patients will undergo restaging PET/CT scans. Patients with evidence of disease progression will be treated off study.

R-HIDAC After lenalidomide-RCHOP phase, patients without evidence of progressive disease will receive rituximab 375 mg/m^2 day 1 and then patients will be admitted for high-dose cytarabine (HIDAC). Recommended age-adjusted HIDAC doses are as follows: ≤65 years: 3 g/m2 every12 hours X 4 doses; 65-70 years: 2 g/m^2 every12 hours X 4 doses; >70 years: 1 g/m^2 every12 hours X 4 doses. Physician discretion will dictate the choice of HIDAC dose, ranging from 1 g/m^2 - 3 g/m^2 every 12 hours X 4 doses.

Patients will receive two cycles of rituximab-HIDAC every 3 weeks. After two cycles of R-HIDAC, the patients will undergo restaging PET/CT scans. Patients with evidence of disease progression will be treated off study.

Len-Rituximab Maintenance After completion of induction chemotherapy with Len-RCHOP and R-HIDAC, patients will begin maintenance phase with lenalidomide and rituximab for 6 months. Lenalidomide will be administered at 15 mg orally daily on days 1-21 of a 28-day cycle for a total of 6 cycles and rituximab maintenance every 8 weeks for a total of 3 treatments.

Inclusion criteria

• Previously untreated mantle cell lymphoma patients (at least clinical stage 2)

• Histologic diagnosis confirmed by MSKCC pathologist as mantle cell lymphoma

• Presence of evaluable disease

• Age ≥18 years KPS ≥ 70%

• Adequate organ function: ANC ≥1500 and platelet count ≥100,000, unless felt to be secondary to underlying mantle cell lymphoma

• Renal function assessed by calculated creatinine clearance as follows:

• Cockcroft-Gault estimation of CrCl):

  • Calculated creatinine clearance ≥ 30ml/min by Cockcroft-Gault formula. See section below, "Dosing Regimen", regarding lenalidomide dose adjustment for calculated creatinine clearance ≥30ml/min and < 60ml/min.

• Adequate hepatic function as determined by

  • Total bilirubin <1.5X upper limit of normal (ULN) (unless known Gilbert syndrome)
  • AST (SGOT) and ALT (SGPT) 3 x ULN

• All study participants must be registered into the mandatory Revlimid REMS® program, and be willing and able to comply with the requirements of the REMS® program.

• Females of reproductive potential must adhere to the scheduled pregnancy testing as required in the Revlimid REMS® program.

• Each subject must sign an informed consent form indicating that he or she understand the purpose of and procedures required for the study and are willing to participate.

• Short course systemic corticosteroids is permissible for disease control, improvement of performance status or non-cancer indication if ≤ 10 days and must be discontinued prior to study treatment.

Exclusion criteria

• Known central nervous system (CNS) lymphoma
• Uncontrolled or severe cardiovascular disease or left ventricular ejection fraction <50% as determined by echocardiogram or MUGA.
• Any life-threatening illness, medical condition, or organ system dysfunction which, in the investigator's opinion, could compromise the subject's safety or put the study outcomes at undue risk.
• Pregnant or breast-feeding. Pre-menopausal patients must have a negative serum HCG within 14 days of enrollment.
• Patients using ≥20 mg/day of prednisone (or steroid equivalent dose) for any chronic medical condition
• Known seropositive, requiring anti-viral therapy, and with detectable viral load by PCR for human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV).
• Known hypersensitivity to thalidomide or lenalidomide
• The development of erythema nodosum if characterized by a desquamating rash while taking thalidomide or similar drugs.
• Patients planned for upfront consolidation with high-dose therapy and autologous stem cell transplant.

Description:

Lenalidomide + R-CHOP x 4 cycles R-HiDAC x 2 cycles R-Len maintenance x 6 months. Patients will be followed on active follow up for three years after completion of therapy. After the active followup period, survival, relapse, and new anti-lymphoma therapy information will be collected via telephone calls, patient medical records, and/or clinic visits approximately every 6 months until death, loss to follow up or consent withdrawal, whichever comes first.

Drug: high-dose cytarabine (HIDAC)

Drug: R-CHOP
