About
This randomized pilot clinical trial studies the side effects of tremelimumab with or without tissue cryoablation in treating patients with kidney cancer that has spread to other places in the body. Tremelimumab binds to a protein called cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), which is found on the surface of T cells (a type of white blood cell). Tremelimumab may block CTLA-4 and help the immune system kill cancer cells. Cryoablation is a procedure that uses a hollow, thin tube called a cryoprobe to freeze and destroy cancer tissue. It is not yet known whether tremelimumab with or without cryoablation is effective in treating patients with kidney cancer.
Full description
PRIMARY OBJECTIVES:
I. To evaluate safety of tremelimumab alone and in combination with cryoablation in patients with metastatic renal cell carcinoma (RCC).
SECONDARY OBJECTIVES:
I. To explore the longitudinal values for immunological variables (including cluster of differentiation [CD]4+ ICOS+ T cells; effector to regulatory T cell ratio; absolute lymphocyte count) following treatment with tremelimumab in patients with metastatic RCC, and evaluate difference between combination cryoablation and tremelimumab in comparison to tremelimumab alone.
II. To determine the objective response rate and progression-free survival of patients treated with tremelimumab with or without cryoablation.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM A: Patients receive tremelimumab intravenously (IV) over 60 minutes at weeks 1 and 5. Within 4-6 weeks later, patients undergo surgery or biopsy. After surgery or biopsy, patients receive tremelimumab IV every 4 weeks (Q4W) for 3 doses, and then every 12 weeks (Q12W) in the absence of disease progression or unacceptable toxicity.
ARM B: Patients undergo cryoablation and receive tremelimumab IV over 60 minutes at weeks 1 (2-6 days after cryoablation) and 5. Within 4-6 weeks later, patients undergo surgery or biopsy. After surgery or biopsy, patients receive tremelimumab IV Q4W for 3 doses, and then Q12W in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30, 60, and 90 days, and then every 6 months.

Inclusion criteria
-
Metastatic renal cell carcinoma (clear cell or non clear cell)
- One metastatic site amenable to cryoablation
- Patients with a single metastatic site may be enrolled if that site is amenable to ablation; however these patients will not be counted in secondary measures of response unless there is new disease detected during follow up
- Eligible for cytoreductive nephrectomy, metastasectomy, or repeated biopsy; biopsy site cannot be lung, mediastinal lymph node, or bone (unless soft tissue component)
-
Patients with any number of prior therapies with anti-angiogenic agents or immunotherapy with the exception of any previous anti-CTLA-4 directed agents are allowed; a 2 week washout period is required for all agents, except for bevacizumab where a 4 week washout is required
-
Performance status with Eastern Cooperative Oncology Group (ECOG) score =< 2; patients with performance status of 3 may be considered as long as the decline has been of short duration (< 1 month), and is due to their malignancy and not a comorbid condition (example: pain limiting activity)
-
Patient's with an International Metastatic Renal Cell Carcinoma Database Consortium (IMDC or Heng) score of 3 or less will be included; score greater than 4 will be excluded; 1 point each: requirement of systemic treatment for metastatic disease less than 1 year of original diagnosis of renal cell carcinoma, a serum calcium greater than 10, anemia, neutrophilia, thrombocytosis, ECOG performance status >= 2
-
No history of autoimmune disorders
-
White blood cell (WBC) >= 2000/uL
-
Absolute neutrophil count (ANC) >= 1000/uL
-
Platelets >= 75 x 10^3/uL
-
Hemoglobin >= 9 g/dL
-
Creatinine =< 3 x upper limit of normal (ULN)
-
Alanine aminotransferase (ALT) =< 3.0 x ULN for patients without liver metastases; for patients with liver metastasis ALT =< 5 x ULN is allowed
-
Bilirubin =< 1.5 x ULN (except for patients with Gilbert's syndrome, who must have a total bilirubin =< 3 mg/dL)
-
Ability to understand and willingness to sign a written informed consent document
-
Females of childbearing potential who are sexually active with a non-sterilized male partner and non-sterilized males must use a highly effective method of contraception for 28 days prior to the first dose of investigational product, and must agree to continue using such precautions for 180 days after the final dose of investigational product; cessation of contraception after this point should be discussed with a responsible physician; periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception; they must also refrain from egg cell donation for 180 days after the final dose of investigational product; females of childbearing potential are defined as those who are not surgically sterile (ie, bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or postmenopausal (defined as 12 months with no menses without an alternative medical cause); a highly effective method of contraception is defined as one that results in a low failure rate (ie, less than 1% per year) when used consistently and correctly; the acceptable methods of contraception are: barrier method (e.g. male condom with spermicide, copper T intrauterine device, or levonorgestrel-releasing intrauterine system - Mirena) or hormonal methods (e.g. implants, hormone shot or injection, combined pill, minipill, or patch)
Exclusion criteria
- Unresolved toxicities from prior anticancer therapy, defined as having not resolved to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v)4.03 grade 0 or 1 with the exception of alopecia and laboratory values listed per the inclusion criteria
- Known or suspected autoimmune disease; patients with a history of inflammatory bowel disease (including Crohn's disease and ulcerative colitis) and autoimmune disorders such as rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus or autoimmune vasculitis [e.g., Wegener's granulomatosis] are excluded from this study; patients with a history of Hashimoto's thyroiditis only requiring hormone replacement, type I diabetes, or psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are allowed to participate
- Any condition requiring systemic treatment with corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days prior to first dose of study drug; inhaled steroids and adrenal replacement steroids doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease
- Autoimmune disease: patients with a history of inflammatory bowel disease (including Crohn's disease and ulcerative colitis) and autoimmune disorders such as rheumatoid arthritis, systemic progressive sclerosis (scleroderma), systemic lupus erythematosus or autoimmune vasculitis (e.g., Wegener's granulomatosis) are excluded from this study
- Any underlying medical or psychiatric condition, which in the opinion of the investigator, will make the administration of study drug hazardous or obscure the interpretation of adverse events (AEs), such as a condition associated with frequent diarrhea
