TLR9 Agonist SD-101, Ibrutinib, and Radiation Therapy in Treating Patients With Relapsed or Refractory Grade 1-3A Follicular Lymphoma

Not Recruiting

Trial ID: NCT02927964


This phase Ib/II trial studies the side effects and best dose of toll-like receptor 9 (TLR9) agonist SD-101 when given together with ibrutinib and radiation therapy and to see how well they work in treating patients with Low Grade Follicular Lymphoma, Marginal Zone Lymphoma, or Mantle Cell Lymphoma that has come back after a period of improvement or no longer responds to treatment. Immunostimulants such as TLR9 agonist SD-101 may increase the ability of the immune system to fight infection and disease. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving TLR9 agonist SD-101 with ibrutinib and radiation therapy may induce an immune response and prolong anti-tumor response.

Inclusion Criteria

   - Biopsy confirmed Grade 1 or 2, or 3A follicular lymphoma; mantle cell lymphoma; or
   marginal zone lymphoma. Subjects must have relapsed from or are refractory to prior

   - Subjects must have at least one site of disease that is accessible for intratumoral
   injection of SD 101 (diameter ≥ 10mm), percutaneously.

   - Subjects must have at least one site of measurable disease (see Section 10.2.2 for
   definition of measurable disease) other than the injection site which is not included
   in the radiation field.

   - ECOG Performance Status of 0 or 1

   - Subjects must be 18 years of age or older.

   - Required values for initial laboratory tests:

      1. Absolute neutrophil count (ANC) ≥ 1000/mm3 independent of growth factor support

      2. Platelets: ≥ 100,000/mm3 or ≥ 50,000/mm3 if bone marrow involvement independent
      of transfusion support in either situation

      3. Hemoglobin: ≥ 8 g/dL (may be transfused)

      4. Creatinine: Creatinine clearance > 25 mL/min

      5. AST/ALT: ≤ 3 x ULN

      6. Bilirubin: ≤ 1.5 x ULN (except for subjects with Gilbert's Syndrome or of non
      hepatic origin)

   - Must be at least 4 weeks since treatment with standard or investigational
   chemotherapy, biochemotherapy, surgery, radiation, cytokine therapy, and 8 weeks since
   any monoclonal antibodies or immunotherapy, and recovered from any clinically
   significant toxicity experienced during treatment.

   - Women of childbearing potential and men who are sexually active must be practicing a
   highly effective method of birth control during and after the study consistent with
   local regulations regarding the use of birth control methods for subjects
   participating in clinical trials. Men must agree to not donate sperm during and after
   the study. For females, these restrictions apply for 1 month after the last dose of
   study drug. For males, these restrictions apply for 3 months after the last dose of
   study drug.

   - Women of childbearing potential must have a negative serum (beta human chorionic
   gonadotropin [β-hCG]) or urine pregnancy test at Screening. Women who are pregnant or
   breastfeeding are ineligible for this study.

   - Life expectancy greater than 4 months.

   - Able to comply with the treatment schedule.

   - Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria

   - Autoimmune disease requiring treatment within the last 5 years including systemic
   lupus erythematosus, rheumatoid arthritis, multiple sclerosis, Sjӧgren's syndrome,
   autoimmune thrombocytopenia, uveitis, or other if clinically significant

   - Major surgery or a wound that has not fully healed within 4 weeks of enrollment.

   - History of stroke or intracranial hemorrhage within 6 months prior to enrollment.

   - Requires anticoagulation with warfarin or equivalent vitamin K antagonists.

   - Requires chronic treatment with strong CYP3A inhibitors.

   - Vaccinated with live, attenuated vaccines within 4 weeks of enrollment.

   - Known history of human immunodeficiency virus (HIV) or active Hepatitis C Virus or
   active Hepatitis B Virus infection or any uncontrolled active systemic infection.

   - Known CNS lymphoma.

   - Subjects with a history of prior malignancy with the exception of non melanoma skin
   cancer, carcinoma in situ of the cervix, in situ carcinoma of the bladder, stage 1
   prostate cancer that does not require treatment, or other malignancy that has
   undergone potentially curative therapy with no evidence of disease for the last > 2
   years and that is deemed by the investigator to be a low risk for recurrence.

   - History of allergic reactions attributed to compounds of similar composition to SD 101
   or ibrutinib

   - Treatment with an immunosuppressive regimen of corticosteroids or other
   immunosuppressive medication (eg, methotrexate, rapamycin) within 30 days of study
   treatment. Note: subjects may take up to 5 mg of prednisone or equivalent daily.
   Topical and inhaled corticosteroids in standard doses are allowed.

   - Significant cardiovascular disease (ie, NYHA class 3 congestive heart failure;
   myocardial infarction with the past 6 months; unstable angina; coronary angioplasty
   with the past 6 months; uncontrolled atrial or ventricular cardiac arrhythmias).

   - Pregnant or breast feeding.

   - Any other medical history, including laboratory results, deemed by the investigator to
   be likely to interfere with their participation in the study, or to interfere with the
   interpretation of the results.
