Brief Summary:
This pilot clinical trial studies the side effects of stereotactic body radiation therapy and pazopanib hydrochloride in treating patients with kidney cancer who are not able to undergo surgery. Stereotactic body radiation therapy is a specialized radiation therapy that delivers high doses of radiation directly to the tumor and may kill more tumor cells and cause less damage to normal tissue. Pazopanib hydrochloride may stop the growth of tumor cells by blocking an enzyme needed for cell growth. Giving pazopanib hydrochloride before stereotactic body radiation therapy may help make the tumor smaller and be an alternative treatment for patients who cannot undergo surgery.

Clear Cell Renal Cell Carcinoma Renal Cell Carcinoma Radiation: Stereotactic Radiosurgery Drug: Pazopanib Hydrochloride Not Applicable

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the rate of treatment related toxicity reports following stereotactic body radiation therapy (SBRT) and pazopanib (pazopanib hydrochloride) as a determination of the tolerability of combined therapy in patients with clear cell renal cell carcinoma (RCC).

SECONDARY OBJECTIVES:

I. To determine the tumor diameter/volume change prior to and following pazopanib treatment prior to SBRT.

II. To determine the impact of pre SBRT pazopanib therapy on radiation therapy target volumes for evidence of tumor shrinkage.

III. To evaluate tumor change in radiation therapy target volumes and the incidence of treatment related toxicity reports and sparing of non-involved nephron.

IV. Report change in tumor control following pazopanib and SBRT as evaluated by post treatment repeat biopsy and/or Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

OUTLINE:

Patients receive pazopanib hydrochloride orally (PO) daily for up to 60 days. Patients then continue to receive pazopanib hydrochloride PO daily and undergo SBRT every other day over days 60-65.

After completion of study treatment, patients are followed up at 1, 3, 6, 12, 18, and 24 months.

Primary Outcome Measures :
  1. Incidence of grade 3 and above National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 toxicity attributed to combination treatment [ Time Frame: Up to 180 days post-SBRT ]
    The toxicity profiles will be tabulated by follow-up period (i.e. 30 days and 180 days).


Secondary Outcome Measures :
  1. Response rate, assessed using RECIST [ Time Frame: Up to 24 months ]
    Estimated based on the number of responses using a binomial distribution and its confidence intervals will be estimated using Wilson's method. Factors including patient characteristics that predict response will be identified by logistic regression.

  2. Change in tumor volume [ Time Frame: Baseline to up to 24 months ]
    Summarized by mean ± standard deviation and the difference between two time points (pre and post treatment) will be examined using paired T-test.

  3. Disease-free survival [ Time Frame: From the start of treatment to the date of disease progression or the date of death, whichever comes first, assessed up to 24 months ]
    Summarized by calculating Kaplan-Meier curves. Survival rates estimated from the Kaplan-Meier curves will be estimated with 95% confidence intervals.

  4. Overall survival [ Time Frame: From the start of treatment to the date of death, assessed up to 24 months ]
    Summarized by calculating Kaplan-Meier curves. Survival rates estimated from the Kaplan-Meier curves will be estimated with 95% confidence intervals.

  5. Time to local progression [ Time Frame: From the start of treatment to the date of local progression, assessed up to 24 months ]
    Summarized by calculating Kaplan-Meier curves. Survival rates estimated from the Kaplan-Meier curves will be estimated with 95% confidence intervals.

  6. Time to distant failure [ Time Frame: From the start of treatment to the date of distant metastases, assessed up to 24 months ]
    Summarized by calculating Kaplan-Meier curves. Survival rates estimated from the Kaplan-Meier curves will be estimated with 95% confidence intervals.

  7. Rate of acute side effects [ Time Frame: Up to 180 days after treatment ]
    Summarized as a proportion with 95% confidence intervals.

  8. Rate of late side effects [ Time Frame: Up to 24 months ]
    Summarized as a proportion with 95% confidence intervals.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patient is considered a poor surgical candidate for removal of a renal mass as determined by pre-operative assessment due to the following factors or various combinations thereof:

    • Significant comorbidity precluding ability to deliver anesthesia, without compromised ability to undergo systemic chemotherapy with pazopanib as deemed by the Urologist and Medical Oncologist
    • Medically documented contraindication for surgery due to religion or risk of blood transfusion
    • Size or location of tumor deemed high risk for surgical intervention by Urologist
    • Unacceptable risk for anesthesia, such as history of malignant hyperthermia
    • Any one of these factors may or may not constitute unresectability, but for consideration for this trial, the surgical and medical oncologist must agree that the particular constellation of findings for the patient under consideration would likely entail a low probability (< 50%) that the tumor would be resectable (with negative margins) or that the potential morbidity associated with an attempt at surgical resection would not be clinically acceptable
    • The numerical thresholds noted above are only a guideline and the clinical judgment of the surgeon and medical oncologist will determine unresectability or if patient refuses surgery or other forms of local therapy; the histopathology for this cohort is limited to clear cell carcinoma of the kidney
  • Patient is able to give and sign study specific informed consent
  • Negative serum or urine pregnancy test within 72 hours prior to registration for women of childbearing potential and agrees to use contraception for the duration of the treatment cycle and for a minimum of 30-days following the end of therapy (a minimum estimate 95 days)

    • Serum creatinine < 2.5 mg/dL
    • Urine to protein to creatinine (UPC) ratio < 1; if UPC > 1, then a 24-hour urine protein must be assessed; subjects must have a 24-hour urine protein value < 1 g to be eligible
    • Prothrombin time (PT) or international normalized ratio (INR) and partial thromboplastin time (PTT) < 1.2 X upper limit of normal (ULN)

Exclusion Criteria:

  • Any patient with active connective tissue disease such as lupus, dermatomyositis
  • Major psychiatric illness, which would prevent completion of treatment or interfere with follow-up
  • Prior dose of radiation overlapping the treatment field determined by a study Radiation Oncologist to represent unacceptable risk for additional radiation to be targeted to the field
  • Pregnant and lactating females, and unwillingness to use contraception; or male subject not willing to use contraception during and for 21 days after the last dose of pazopanib therapy
  • Clinically significant gastrointestinal abnormalities that may increase the risk for gastrointestinal bleeding (e.g. active peptic ulcer, ulcerative colitis, Crohn's disease, abdominal fistula) within prior 6 months
