A Phase I/II Study of Intratumoral Injection of SD-101

Completed · Phase 1/Phase 2

Conditions studied: Extranodal Marginal Zone B-cell Lymphoma of Mucosa-associated Lymphoid Tissue, Nodal Marginal Zone B-cell Lymphoma, Recurrent Grade 1 Follicular Lymphoma, Recurrent Grade 2 Follicular Lymphoma, Recurrent Marginal Zone Lymphoma, Recurrent Small Lymphocytic Lymphoma, Splenic Marginal Zone Lymphoma

In brief

This phase 1-2 trial studies the side effects and best dose of ipilimumab in combination with toll-like receptor 9 (TLR9) agonist SD-101 and radiation therapy in treating patients with recurrent low-grade B-cell lymphoma.

• No active or chronic infection with human immunodeficiency virus (HIV), Hepatitis B, or Hepatitis C
• 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 reproductive potential must have negative urine pregnancy test
• 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

You may not qualify if…

• Pre-existing autoimmune or antibody mediated disease including systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, Sjogren's syndrome, autoimmune thrombocytopenia, Addison's disease, but excluding the presence of auto-antibodies without clinical autoimmune disease
• History of inflammatory bowel disease (eg, Crohn's disease or ulcerative colitis), celiac disease, or other chronic gastrointestinal conditions associated with diarrhea, or current acute colitis of any origin
• Any history of diverticulitis, or evidence of diverticulitis at baseline, including evidence limited to computed tomography (CT) scan only (note diverticulosis is not an exclusion criterion)
• Severe psoriasis
• Active thyroiditis
• History of uveitis
• Known history of HIV; patients with Acquired Immunodeficiency Syndrome (AIDS) are excluded
• Patients with active infection or with a fever > 38.5 degrees C within 3 days prior to the first scheduled treatment
• Central nervous system (CNS) lymphoma
• Prior malignancy (active within 5 years of screening) except basal cell or completely excised non-invasive squamous cell carcinoma of the skin, or in situ squamous cell carcinoma of the cervix
• History of allergic reactions attributed to compounds of similar composition to SD-101 or ipilimumab (anti-cytotoxic T-lymphocyte-associated protein 4 [CTLA4] antibodies)
• Current anticoagulant therapy (EXCEPTION acetylsalicylic acid ≤ 325 mg per day allowed)
• Treatment with an immunosuppressive regimen of corticosteroids or other immunosuppressive medication (eg, methotrexate, rapamycin) within 30 days of study treatment; note patients with adrenal insufficiency may take up to 5 mg of prednisone or equivalent daily; topical and inhaled corticosteroids in standard doses are allowed
• Significant cardiovascular disease [ie, New York Heart Association (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 lactating
• 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.
