Lenalidomide and Combination Chemotherapy (DA-EPOCH-R) in Treating Patients With MYC-Associated B-Cell Lymphomas

Prospective, Multi-center Phase I/II Trial of Lenalidomide and Dose-Adjusted EPOCH-R in MYC-Associated B-Cell Lymphomas

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 v-myc myelocytomatosis viral oncogene homolog (avian) (MYC)-associated B-cell lymphomas. Lenalidomide may stop the growth of B-cell lymphomas by blocking the growth of new blood vessels necessary for cancer growth and by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as etoposide, prednisone, vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, 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. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Giving lenalidomide together with combination chemotherapy may be an effective treatment in patients with B-cell lymphoma.

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of lenalidomide when added to dose-adjusted (DA)-etoposide, prednisone, vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, rituximab (EPOCH-R) (hereby termed "DA-EPOCH-RR") in patients with double hit lymphoma (DHL) lymphomas. (Phase I) II. To determine the 1- and 2-year progression free survival (PFS) of DA-EPOCH-RR in patients with DHL lymphomas. (Phase II)

SECONDARY OBJECTIVES:

I. Overall response rate, complete response, and duration of response. II. Quality of life (QOL) measures using standardized scales. III. Toxicity assessment using version 4.0 of the National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) criteria.

IV. Overall survival (OS) at 1 and 2 years.

OUTLINE: This is a phase I, dose-escalation study of lenalidomide followed by a phase II study.

INDUCTION PHASE: Patients receive lenalidomide orally (PO) daily on days 1-14. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity.

DA-EPOCH-R: Patients receive etoposide intravenously (IV) continuously on days 1-4, prednisone PO twice daily (BID) on days 1-5, vincristine sulfate IV continuously on days 1-4, doxorubicin hydrochloride IV continuously on days 1-4, cyclophosphamide IV over 15 minutes on day 5, and rituximab IV over 4 hours on day 1 (per institutional guidelines). Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION PHASE: Patients who are transplantation (hematopoietic stem cell transplant [HSCT])-eligible receive BCNU, etoposide, cytarabine, and melphalan (BEAM)-conditioning regimen followed by autologous (auto)-HSCT or HSCT at the discretion of the treating physician. Patients who do not undergo HSCT in first remission receive lenalidomide maintenance for 12 months.

After completion of study treatment, patients are followed up for every 3 months for 1 year, every 4 months for 1 year, and then periodically for 1 year.

Inclusion Criteria

1. B-cell lymphoma with comprehensive immunohistochemistry (IHC) panel establishing lineage (CD20, CD3) and cell of origin (CD10, BCL6 and MUM1) in addition to proliferative/prognostic markers (Ki-67, C-myc and BCL2). DHL will be identified using cytogenetics and/or immunohistochemistry as detailed in section 4.1.2 below.

2. To define DHL, patients must have evidence of C-myc [defined as: Cytogenetic evidence (FISH or karyotype) of C-myc breaks (Increased copy number in itself is not considered positivity for C-myc) OR Positive IHC defined as >40% of the lymphoma cells staining for C-myc] PLUS either:

   1. Breaks in BCL-2 via cytogenetic studies or
   2. BCL-2 immunopositivity in >70% of lymphoma cells.

3. Patients are allowed to have received radiotherapy before enrollment if radiation was given to alleviate pain and/or neurologic compromise as long as there remains areas of measurable disease present. Further, at the investigator's discretion and for patients who are unstable, one cycle of R-CHOP is allowed prior to enrollment but no more than one cycle. For purposes of this trial, prednisone or other corticosteroids used for non-lymphomatous conditions will be allowed. In addition, a prior/recent short course (< 2 weeks) of steroids for symptom relief of lymphoma-related symptoms will be allowed.

4. AST and ALT < 3 x upper limit of normal (ULN), and total bilirubin <1.5 x ULN (with exception of patients with Gilbert's syndrome, asymptomatic gallstones, liver involvement with NHL or stable chronic liver disease per investigator assessment).

5. Patients must have adequate renal function by virtue of GFR > 50 ml/minute using Cockroft-Gault formula.

6. Patients must have adequate bone marrow function (platelets >100,000 and ANC >1,200). Patients with bone marrow involvement are allowed at the investigator's discretion regardless of cytopenias.

7. ECOG PS 0-2.

8. Age ≥ 18 years.

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

10. Females of reproductive potential must adhere to the scheduled pregnancy testing as required in the lenalidomide REMS® program. (Please see study schema for further details)

11. Able to take aspirin (81 or 325 mg) daily as prophylactic anticoagulation (patients intolerant to ASA may use warfarin or low molecular weight heparin).

12. Ability to read, understand, and sign a written informed consent approved by each institutional IRB. Alternatively, patients with legal guardians who can read, understand, and sign written informed consent may also enroll.

Exclusion Criteria

1. Prior therapy for lymphoma
2. Known CNS involvement
3. Known HIV positive status
