Romidepsin and Lenalidomide in Treating Patients With Previously Untreated Peripheral T-Cell Lymphoma

Phase II Study of Romidepsin Plus Lenalidomide for Patients With Previously Untreated PTCL

The purpose of this study is to evaluate how safe and effective the combination of the study drugs romidepsin and lenalidomide is for treating patients with peripheral t-cell lymphoma (PTCL) who have not been previously treated for this cancer. Currently, there is no standard treatment for patients with PTCL; the most common treatment used is a combination of drugs called CHOP, but this can be a difficult treatment to tolerate because of side effects, and is not particularly effective for most patients with PTCL. Romidepsin (Istodax®) is a type of drug called an HDAC inhibitor. It interacts with DNA (genetic material in cells) in ways that can stop tumors from growing. It is given as an infusion through the veins. Lenalidomide (Revlimid®) is a type of drug known as an immunomodulatory drug, or IMID for short. This drug affects how tumor cells grow and survive, including affecting blood vessel growth in tumors. It is given as an oral tablet (by mouth).

PRIMARY OBJECTIVES:

I. To evaluate the efficacy of the combination of romidepsin plus lenalidomide in patients with previously untreated peripheral T-cell lymphoma (PTCL).

SECONDARY OBJECTIVES:

I. Evaluate the safety of the combination of romidepsin and lenalidomide. II. Further evaluate efficacy of the combination of romidepsin and lenalidomide.

III. Evaluate the delay to cytotoxic chemotherapy.

TERTIARY OBJECTIVES:

I. Evaluate the use of Northwestern Medicine (NM) positron emission tomography (PET)/computed tomography (CT) vs CT imaging in PTCL.

II. Validate a new prognostic model for newly diagnosed PTCL. III. Investigate the tumor immunohistochemical profile to identify potential biomarkers associated with prognosis and treatment response.

OUTLINE:

Patients receive romidepsin intravenously (IV) over 4 hours on days 1, 8, and 15 and lenalidomide orally (PO) once daily (QD) on days 1-21. Treatment repeats every 28 days for up to 1 year in the absence of disease progression, inter-current illness that prevents further administration of treatment, unacceptable toxicity, patient decides to withdraw from study treatment (or study as a whole), or general or specific changes in the patient's condition render the patient unacceptable for further treatment in the judgment of the treating investigator.

After completion of study treatment, patients are followed up every 3 months for 1 year and then every 6 months for 3 years.

Inclusion Criteria:

• Histologically confirmed diagnosis of PTCL (using the most recent edition of the World Health Organization [WHO] Classification of Tumors of Hematopoietic and Lymphoid Tissues as guidance) including:

  • Anaplastic large cell lymphoma, anaplastic large cell kinase (ALK)-negative

  • Hepatosplenic gamma-delta T-cell lymphoma
  • Peripheral T-cell lymphoma, unspecified (not otherwise specified [NOS])
  • Transformed mycosis fungoides
  • Subcutaneous panniculitis-like T-cell lymphoma.
  • NOTE: Patients with adequate archived (well-preserved, formalin-fixed) biopsy tissue remaining will be required to submit a portion for exploratory studies; this is not optional if tissue is available; however, lack of adequate tissue for exploratory studies will not preclude patients from participating

• Patients must have bi-dimensionally measurable disease (>= 1 cm) by CT imaging

  • NOTE: Patients with marrow-only disease are eligible; response for these patients will be assessed by repeat bone marrow biopsy

• Patients must fit into one of the following categories:

  • Age >= 18 years to < 60 years with a cumulative illness rating scale (CIRS) score >= 6 OR deemed ineligible for cytotoxic chemotherapy by the treating investigator
  • >= 60 years

• Patients must have adequate organ and marrow function (documented within 14 days prior to registration) as outlined below:

  • Absolute neutrophil count (ANC) >= 750/mcl
  • Hemoglobin >= 8 g/dl
  • Platelets >= 50,000/mcl
  • Total bilirubin =< 2 x upper limit normal (ULN)
  • Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum pyruvate glutamate transaminase [SPGT]) =< 3 x ULN
  • Creatinine =< 2 x ULN

• Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status =< 2

• All patients must agree to use effective contraception while on study, and all patients must agree to undergo counseling sessions every 28 days about pregnancy precautions and risks of fetal exposure

  • Females of childbearing potential (FCBP) must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control: one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before starting lenalidomide, during lenalidomide therapy, during dose interruptions, and for at least 28 days following discontinuation of lenalidomide therapy

  • Males receiving lenalidomide must agree to use a latex condom during any sexual contact with FCBPs even if they have undergone a successful vasectomy

  • NOTE: A FCBP is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

    • Has not undergone a hysterectomy or bilateral oophorectomy
    • Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)

  • FCBP should be referred to a qualified provider of contraceptive methods, if needed

• FCPB must have a negative urine or serum pregnancy test within 7 days prior to registration, and be willing to adhere to the scheduled pregnancy testing as required in the Revlimid Risk Evaluation and Mitigation Strategies (REMS®) program

  • NOTE: Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

• Patients must be free of any prior malignancies for >= 1 year

  • NOTE: The exception to this would be currently treated squamous cell and basal cell carcinoma of the skin, carcinoma in situ of the cervix, breast, or bladder, or surgically removed melanoma in situ of the skin (stage 0) with histologically confirmed free margins of excision

• 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

• Patients must have the ability to understand and the willingness to sign a written informed consent prior to registration
