CpG-STAT3 siRNA CAS3/SS3 and Localized Radiation Therapy for the Treatment of Relapsed/Refractory B-Cell NHL

Korábbi kezelés

• Patients may not be receiving any other investigational agents, or concurrent biological, chemotherapy, or radiation therapy
• Treatment with corticosteroids or other systemic immunosuppressive medication (e.g., methotrexate, rapamycin) within 28 days of study treatment. Note: patients with adrenal insufficiency may take up to 7.5 mg of prednisone or equivalent daily. Topical and inhaled corticosteroids in standard doses are allowed
• Pregnant or lactating women are excluded from this study because CAS3/SS3is an agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with CAS3/SS3, breastfeeding should be discontinued if the mother is treated with CAS3/SS3
• Patients with active infection or with a fever > 38.5 degrees Celsius (C) within three days prior to the first scheduled treatment

Más betegség

• Current use of anticoagulant therapy (aspirin [ASA] =< 325 mg per day allowed) or history of significant bleeding diathesis
• Patients with rapid progression of disease requiring immediate anti lymphoma therapy
• Patients should not have any uncontrolled illness including ongoing or active infection
• 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
• 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 autoantibodies without clinical autoimmune disease
• History of inflammatory bowel disease (e.g., Crohn's disease or ulcerative colitis), celiac disease, or other chronic gastrointestinal conditions associated with diarrhea, or current acute colitis of any origin
• History of diverticulitis (even a single episode) or evidence of diverticulitis at baseline, including evidence limited to computed tomography (CT) scan only. Note: diverticulosis is not an exclusion criterion per se
• Graft versus host disease
• History of uveitis
• Known history of human immunodeficiency virus (HIV) with detectable viral load or patients with acquired immuno-deficiency syndrome (AIDS) are excluded
• Known active or chronic viral hepatitis B or C infection
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to CAS3/SS3
• Significant cardiovascular disease (i.e. New York Heart Association [NYHA] >= class 3 congestive heart failure; myocardial infarction within the past 6 months; unstable angina; coronary angioplasty within the past 6 months; uncontrolled atrial or ventricular cardiac arrhythmias)
• Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures

Laborértékek

• History of allergic reactions attributed to compounds of similar composition to agatolimod sodium (PF-3512676) or tremelimumab

Egyéb

• Severe psoriasis
• Active thyroiditis
• Active central nervous system (CNS) metastases
• Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)

• All subjects must have the ability to understand and the willingness to sign a written informed consent
• Age 18 and older
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 (corresponds to Karnofsky Performance Status [KPS] of >= 70)
• Life expectancy greater than 16 weeks
• Relapsed/refractory disease; patients must have failed >= 2 prior systemic therapies and have no treatment options known to provide clinical benefit
• Biopsy confirmed relapsed or refractory B-cell lymphoma of the following subtypes; patients with a partial response to a previous treatment are allowed.
  • Follicular grade 1 or 2, or 3 marginal zone or small lymphocytic lymphoma
  • Diffuse large B-cell lymphoma, non-germinal center B-cell like (GCB) type determined by immunohistochemistry using Han's algorithm
  • Mantle cell lymphoma
• Patients must have at least two separate tumor sites, one of which is at least 2 cm in diameter and peripherally accessible and amenable for intratumoral injection of CAS3/SS3 with stabilization by palpation, and the other is at least 1.5 cm in diameter
• Tumor specimens must be available for immunological studies either from a previous biopsy or a new biopsy obtained before the initiation of the study. Paraffin-embedded specimens are acceptable
• Required wash out periods for prior therapy:
  • Topical therapy: 2 weeks
  • Chemotherapy: 4 weeks
  • Radiotherapy: 4 weeks
  • Other investigational therapy: 4 weeks
  • Monoclonal antibody or immunotherapy: 4 weeks
  • Targeted therapies: 4 weeks
  • Allogeneic transplant: 6 months
• Absolute neutrophil count (ANC) >= 1,000/mm\^3
  • NOTE: Growth factor is not permitted within 14 days of ANC assessment unless cytopenia is secondary to disease involvement
• Platelets >= 75,000/mm\^3
  • NOTE: Platelet transfusions are not permitted within 14 days of platelet assessment unless cytopenia is secondary to disease involvement
• Hemoglobin >= 8 g/dl
• Total serum bilirubin (mg/dL): =< 1.5 x upper normal limit (ULN)
• Aspartate aminotransferase (AST) < 3 x ULN without liver metastasis and < 5 x ULN with liver metastasis
• Alanine aminotransferase (ALT) < 3 x ULN without liver metastasis and < 5 x ULN with liver metastasis
• Adequate renal function as determined by serum creatinine =< 2.0 mg/dL or creatinine clearance of >= 50 mL/min per the Cockcroft-Gault formula

• The effects of CAS3/SS3 on the developing fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for six months following duration of study participation. Should a woman become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately
