13NHL-12-1: PHI-69 A Phase I Study of Ipilimumab in Combination with Rituximab in Patients with Relapsed/Refractory CD20+ B-Cell Lymphoma

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.

Phase

Phase 1 - a new treatment that has not been tested, and researchers are looking for the best way to administer the treatment and how much can be given safely. Phase I trials are usually offered only to patients with advanced disease who would not be helped by other known treatments. Some patients are helped by these treatments, although in this early stage physicians don’t really know if the treatment will be effective.

Inclusion and Exclusion Criteria

  • Serum creatinine =< 2.0 x upper limit of normal OR calculated creatinine clearance >= 30 ml/min/1.73 M^2 by the modified Cockcroft and Gault formula OR creatinine clearance >= 30 mL/min obtained from a 24-hour urine collection
  • At least one measurable lesion according to international workshop lymphoma response criteria; there must be measurable lymphadenopathy to follow with serial exam and/or imaging
  • All previous cancer therapy, including radiation, hormonal therapy and surgery, must have been discontinued at least 4 weeks prior to treatment in this study
  • Patients must have evidence of progression of disease during or after last treatment
  • Submission of original biopsy for review and verification by participating center hematopathologist
  • Disease free of prior malignancies for >= 3 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma "in situ" of the cervix or breast

  • 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 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
  • Patients with chronic human immunodeficiency virus (HIV), hepatitis B or hepatitis C infections are excluded
  • Pregnant women are excluded from this study
  • HIV-positive patients on combination antiretroviral therapy are ineligible
