A Study to Evaluate the Use of Nivolumab and Pomalidomide Combination for Relapsed/Refractory Primary Central Nervous System Lymphoma and Primary Vitreoretinal Lymphoma

Overview

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The purpose of this study is to evaluate the side effects and best dose of pomalidomide when given together with dexamethasone in treating patients with primary central nervous system lymphoma that has come back (relapsed) or does not respond to treatment (refractory) or intraocular lymphoma that is newly diagnosed, relapsed or refractory. Pomalidomide may stimulate the immune system to kill cancer cells. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, stopping them from dividing, or by stopping them from spreading. Giving pomalidomide together with dexamethasone may kill more cancer cells.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

See eligibility criteria

Inclusion Criteria: 

  • Relapsed or refractory primary central nervous system (CNS) diffuse large B cell lymphoma (PCNSDLBCL) with a CNS lesion, with cerebrospinal fluid (CSF) relapse with positive CSF cytology, or with ocular relapse with positive ocular tissue biopsy.
    • NOTE: tissue biopsy is not absolutely necessary for CNS tumor unless clinical and radiologic findings strongly suggest other etiologies as per treating physician; initial diagnosis must be made by tissue biopsy.
    • NOTE: patients with B-cell lymphoma with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma are also eligible for the protocol as long as they meet other criteria; patients with typical Burkitt lymphoma are not eligible.
  • Relapsed/refractory primary vitreoretinal diffuse large B cell lymphoma (DLBCL) with a CNS lesion, with CSF relapse with positive CSF cytology, or with ocular relapse with positive ocular tissue biopsy.
    • NOTE: tissue biopsy requirement of the CNS lesion is as outlined in bullet above.
  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1, 2 or 3. 
  • Absolute neutrophil count (ANC) >= 1000/uL. 
  • Platelets (PLT) >= 100,000/uL. 
  • Total bilirubin =< 1.5 x upper limit of normal (ULN) or if total bilirubin is > 1.5 x ULN the direct bilirubin must be =< 1.5 x ULN (=< 0.45 mg/dL). 
  • Aspartate aminotransferase (AST) =< 3 x ULN - Creatinine =< 2.5 x ULN. 
  • Females of reproductive potential must be willing to adhere to the scheduled pregnancy testing as required in the POMALYST REMS (TM) program. 
  • Able to take aspirin (81 or 325 mg) daily as prophylactic anticoagulation (patients intolerant to acetylsalicylic acid [ASA] may use warfarin or heparin).
  • Provide informed written consent.
  • Willing to return to participating medical institutions for follow-up. 
  • Willing to provide tissue samples for correlative research purposes.
  • Willing to be registered into the mandatory POMALYST REMS (TM) program, and willing and able to comply with the requirements of the POMALYST REMS (TM) program.

Exclusion Criteria:

  • Pregnant women.
  • Nursing women. 
  • Men or women of childbearing potential who are unwilling to employ adequate contraception. 
  • The development of erythema nodosum if characterized by a desquamating rash while taking thalidomide or similar drugs. 
  • Uncontrolled infection. 
  • Therapy with myelosuppressive chemotherapy or biologic therapy < 21 days prior to registration.
  • NOTE: patients who have recovered from cytopenia related to previous treatment and meet criteria of this protocol will be eligible. 
  • Persistent toxicities >= grade 3 from prior chemotherapy or biological therapy regardless of interval since last treatment.
  • History of thromboembolic episodes =< 3 months prior to registration .
  • Other concurrent chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy considered investigational (utilized for a non-Food and Drug Administration [FDA]-approved indication and in the context of a research investigation). 
  • Immunodeficiency states including human immunodeficiency virus (HIV) infection. 
  • Active hepatitis B or C with uncontrolled disease.
    • NOTE: a detailed assessment of hepatitis B/C medical history and risk factors must be done at screening for all patients; hepatitis B core immunoglobulin M antibody (HBcIgM Ab), hepatitis B surface antigen (HBsAg) and hepatitis C antibody screen (HCV Ab Scrn) w/reflex testing are required at screening for all patients with a positive medical history based on risk factors and/or confirmation of prior hepatitis B (HBV) infection. 
  • Active other malignancy requiring treatment that would interfere with the assessments of response of the lymphoma to protocol treatment.
  • Inability to swallow or impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of the drugs (e.g., ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome or small bowel resection) that would preclude use of oral medications.
  • Any severe and/or uncontrolled medical conditions or other conditions that, in the treating physician's opinion, could adversely impact their ability to participate in the study. 
  • Major surgery =< 4 weeks prior to registration or have not recovered from side effects of such therapy. 
  • New York Heart Association classification III or IV.
