Overview
Brief Summary
This partially randomized phase I trial studies the side effects and best dose of ipilimumab when given together with rituximab in treating patients with B-cell lymphoma that has returned or has not responded to treatment. Monoclonal antibodies, such as ipilimumab and rituximab, may interfere with the ability of cancer cells to grow and spread.
Detailed Description
PRIMARY OBJECTIVES: I. To determine a recommended phase II dose for ipilimumab in combination with rituximab. SECONDARY OBJECTIVES: I. To obtain preliminary information on the effect of adding ipilimumab to rituximab in regard to: immune response; clinical anti-tumor response/overall remission rate (ORR) (complete remission + partial remission); progression free survival (PFS). OUTLINE: This is a dose-escalation study of ipilimumab followed by a randomized study. PART I: INDUCTION: Patients receive ipilimumab intravenously (IV) over 90 minutes once every 3 weeks for 12 weeks and rituximab IV over 2-6 hours once weekly for 4 weeks. MAINTENANCE: Patients receive ipilimumab IV over 90 minutes and rituximab IV over 2-6 hours once every 12 weeks for up to 1 year. PART II: Patients are randomized to 1 of 2 treatment arms. ARM A: Patients receive rituximab IV over 2-6 hours once weekly in weeks 1-4 and ipilimumab IV over 90 minutes once weekly in weeks 1, 4, 7, and 10. Patients then receive ipilimumab IV over 90 minutes and rituximab IV over 2-6 hours once every 12 weeks for up to 1 year in the absence of disease progression or unacceptable toxicity. ARM B: Patients receive rituximab IV over 2-6 hours once weekly in weeks 1-4 and ipilimumab IV over 90 minutes once weekly in weeks 3, 6, 9, and 12. Patients then receive ipilimumab IV over 90 minutes and rituximab IV over 2-6 hours once every 12 weeks for up to 1 year in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 12 months.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Previously treated, histologically confirmed cluster of differentiation (CD)20+ B cell lymphoma; bone marrow biopsies as the sole means of diagnosis are not acceptable, but they may be submitted in conjunction with nodal biopsies or extra nodal biopsies; fine needle aspirates are not acceptable
- •All patients must be informed of the investigative nature of the clinical trial and give written informed consent in accordance with institutional and federal guidelines
- •Able to adhere to the study visit schedule and other protocol requirements
- •Karnofsky \>= 70%
- •Life expectancy expected to be greater than 3 months
- •Leukocytes \>= 3,000/mcL
- •Absolute neutrophil count \>= 1,000/mcL
- •Platelets \>= 50,000/mcL
- •Total bilirubin =\< 2.0 x institutional upper limit of normal
- •Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2.5 x institutional upper limit of normal
Exclusion Criteria
- •Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
- •Patients with a history of prior treatment with ipilimumab
- •Patients with a history of prior treatment with an anti-programmed cell death (PD) 1 antibody, CD137 agonist or other immune activating therapy such as anti-CD 40 antibody are excluded unless 5 half-lives of the agent (minimum of 8 weeks) have intervened since the therapy; patients who have received prior vaccine therapy are eligible
- •Patients who are receiving any other investigational agents
- •Autoimmune disease: patients with a history of inflammatory bowel disease, including ulcerative colitis and Crohn's disease, are excluded from this study, as are patients with a history of symptomatic disease (e.g., rheumatoid arthritis, systemic progressive sclerosis \[scleroderma\], systemic lupus erythematosus, autoimmune vasculitis \[e.g., Wegener's granulomatosis\]); central nervous system (CNS) or motor neuropathy considered of autoimmune origin (e.g. Guillain-Barre syndrome and myasthenia gravis, multiple sclerosis)
- •Patients with known immune impairment who may be unable to respond to anti-cytotoxic T-lymphocyte antigen 4 (CTLA 4) antibody
- •Patients with known uncontrolled brain metastases are excluded; however, patients with stable brain disease (off corticosteroids) at least 2 weeks after completion of appropriate therapy for their brain metastases are eligible
- •History of allergic reactions attributed to compounds of similar chemical or biologic composition to rituximab
- •Patients on systemic corticosteroids (except for patients on stable doses of hormone replacement therapy such as hydrocortisone), or other immunosuppressants (e.g., infliximab, mycophenolate mofetil) are excluded
- •Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Outcomes
Primary Outcomes
Incidence of toxicities according to the Common Terminology Criteria for Adverse Events version 4
Time Frame: Up to 12 months
Tables will be created to summarize the toxicities and side effects by dose, course, organ and severity.
Secondary Outcomes
- Immune response as measured by the frequency of activated T-cells, absolute lymphocyte count, antibody dependent cell-mediated cytotoxicity, and kinetics and magnitude of B-cell depletion(Up to 14 weeks)
- Clinical anti-tumor response (complete response and partial response as per international workshop lymphoma response criteria [Cheson 2007])(Up to 12 months)
- Progression-free survival(From when the patient started treatment to the time the patient is first recorded as having disease relapse/progression, or to the date of death if the patient dies due to causes other than disease progression, assessed up to 12 months)
