A Phase I/II Trial of CHOEP Chemotherapy Plus Lenalidomide as Front Line Therapy for Patients With Stage II, III and IV Peripheral T-Cell Non-Hodgkin's Lymphoma
A Phase I/II Trial of CHOEP Chemotherapy Plus Lenalidomide as Front Line Therapy for Patients With Stage II, III and IV Peripheral T-Cell Non-Hodgkin's Lymphoma
This phase I/II trial studies the side effects and best dose of lenalidomide when given together with combination chemotherapy and to see how well they work in treating patients with newly diagnosed stage II-IV peripheral T-cell non-Hodgkin's lymphoma. Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Lenalidomide may stop the growth of peripheral T-cell non-Hodgkin's lymphoma by blocking the growth of new blood vessels necessary for cancer growth. Giving combination chemotherapy with lenalidomide may be a better treatment for peripheral T-cell non-Hodgkin's lymphoma.
PRIMARY OBJECTIVES:
I. To assess the safety and efficacy of lenalidomide in combination with standard induction therapy (CHOEP- cyclophosphamide, doxorubicin [doxorubicin hydrochloride], etoposide, vincristine [vincristine sulfate] and prednisone) in patients with newly diagnosed stage II, III and IV peripheral T-cell lymphoma not otherwise specified (NOS), anaplastic large cell lymphoma (anaplastic lymphoma receptor tyrosine kinase [ALK] negative) (ALK positive if International Prognostic Index [IPI] 3, 4, or 5), angioimmunoblastic T-cell lymphoma, enteropathy associated T-cell lymphoma or hepatosplenic gamma delta T-cell lymphoma.
II. To establish the maximum tolerated dose of lenalidomide in combination with CHOEP chemotherapy. (Phase I) III. To assess the efficacy (complete response rate) of this combination. (Phase II)
SECONDARY OBJECTIVES:
I. To evaluate overall response rate (complete response [CR] + partial response [PR]) of the combination of lenalidomide and CHOEP chemotherapy.
II. To evaluate the safety and tolerability of the regimen. III. To assess the 2 year progression free survival (PFS) and overall survival (OS) using this regimen.
OUTLINE: This is a phase I, dose-escalation study of lenalidomide, followed by a phase II study.
Patients receive cyclophosphamide intravenously (IV), doxorubicin hydrochloride IV and vincristine sulfate IV on day 1, etoposide IV over 30-60 minutes on days 1-3, prednisone orally (PO) on days 1-5, and lenalidomide PO on days 1-10. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. Patients responding after 6 courses of treatment may then undergo an autologous stem cell transplant or receive maintenance lenalidomide at the discretion of the physician or patient choice as follows:
TRANSPLANT: Patients undergo autologous stem cell transplant per standard of care.
MAINTENANCE LENALIDOMIDE: Patients receive lenalidomide PO on days 1-21. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year.
Inclusion Criteria:
Histologically confirmed new diagnosis of stage II, III and IV peripheral T-cell non-Hodgkin's lymphoma not otherwise specified (NOS), anaplastic large cell lymphoma (ALK negative) (ALK positive if IPI 3, 4, or 5), angioimmunoblastic T-cell lymphoma, enteropathy associated T-cell lymphoma, hepatosplenic gamma delta T-cell lymphoma
Pathology material: hematoxylin and eosin (H&E) stain and immunohistochemistry (IHC) slides or a representative formalin-fixed paraffin-embedded (FFPE) tissue block along with the pathology report from initial diagnosis, should be sent to be reviewed, and the diagnosis confirmed by Mayo Clinic department (retrospective diagnostic review: treatment may commence prior to the Mayo Clinic review)
No prior therapy with the exception of prior radiation therapy and/or prednisone alone, at the discretion of the investigator based on current diagnosis and clinical condition; this prednisone treatment will not count toward the 6 cycles of treatment given in the study
Expected survival duration of > 3 months
Karnofsky performance status > 70
Absolute neutrophil count (ANC) > 1000 cells/mm^3, unless cytopenias due to non-Hodgkin lymphoma (NHL) (i.e., bone marrow involvement or splenomegaly)
Platelet count > 100,000/uL or > 75,000/uL if bone marrow (BM) involvement or splenomegaly
Total bilirubin =< 1.5 x upper normal limit, or =< 3 x upper normal limit if documented hepatic involvement with lymphoma, or =< 5 x upper normal limit if history of Gilbert's disease
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x upper normal limit (=< 5 x upper normal limit if documented hepatic involvement with lymphoma)
Serum creatinine < 2.0 mg/dL or calculated creatinine clearance (CrCl) > 45 mL/min (Cockcroft-Gault)
Prothrombin time (PT) or international normalized ratio (INR), and partial thromboplastin time (PTT) =< 1.5 x upper limit of normal unless patient is receiving anticoagulants; if patient is on warfarin therapy, levels should be within therapeutic range
If currently not on anticoagulation medication, willing and able to take aspirin (81 or 325 mg) daily; if aspirin is contraindicated, the patient may be considered for the study if on therapeutic dose warfarin or low molecular weight heparin; patients unable to take any prophylaxis are not eligible
Patients with measurable disease; patients with non-measurable but evaluable disease may be eligible after discussion with the principal investigator (PI); baseline measurements and evaluations must be obtained within 6 weeks of registration to the study; abnormal positron emission tomography (PET)/computed tomography (CT) scans will not constitute evaluable disease, unless verified by CT scan or other appropriate imaging
Patients with measurable disease must have at least one objective measurable disease parameter; a clearly defined, bi-dimensionally measurable defect or mass measuring at least 1.5 cm in diameter on the CT portion of a PET/CT or CT scan or magnetic resonance imaging (MRI) (if appropriate) will constitute measurable disease; proof of lymphoma in the liver is required by a confirmation biopsy; skin lesions can be used as measurable disease provided bi-dimensional measurements are possible
All study participants must be registered into the mandatory Revlimid Risk Evaluation and Mitigation Strategy (REMS) program, and be willing and able to comply with the requirements of the REMS program
Women must not be pregnant or breast-feeding
Male and female patients of reproductive potential must agree follow accepted birth control measures
Patient must be able to adhere to the study visit schedule and other protocol requirements
Patients must be willing to give written informed consent, and sign an institutionally approved consent form before performance of any study-related procedure not part of normal medical care as noted above; with the exception of 1 cycle of chemotherapy based on current diagnosis and clinical condition, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care
No serious disease or condition that, in the opinion of the investigator, would compromise the patient's ability to participate in the study
