Trial Description

Summary

To evaluate efficacy and safety of pazopanib compared to placebo in patients with locally advanced and/ or metastatic renal cell carcinoma (RCC). Approximately 350-400 eligible patients will be stratified and randomized in a 2:1 ratio to receive either 800 mg pazopanib once daily or matching placebo. The study treatment will continue until patients experience disease progression, unacceptable toxicity or death. Primary objective of the study is to evaluate and compare the two treatment arms for progression-free survival. Principal secondary objective is to evaluate and compare the two treatment arms with respect to overall survival. Other objectives are overall response rate [complete response (CR) + partial response (PR)], rate of CR + PR + 6 months stable disease, and the incidence, severity and causality of adverse events and serious adverse events. Safety and efficacy assessments will be regularly performed on all patients. An Independent Data Monitoring Committee will be established to monitor safety during the course of the study and to evaluate interim efficacy data on overall survival.

Eligibility Criteria

Inclusion Criteria:

A patient will be considered for inclusion in this study only if all of the following criteria apply:

  • Signed written informed consent.
  • Diagnosis of clear cell RCC that is predominantly clear cell histology. Note: cytology cannot be the only pathologic criteria to confirm clear cell RCC. Patients with tumor types that are interpreted as non-clear cell, e.g. papillary, are excluded.
  • Locally advanced RCC (defined as disease not amenable to curative surgery or radiation therapy) or metastatic RCC (equivalent to Stage IV RCC according to American Joint Committee on Cancer (AJCC) staging.
  • Note: If the metastatic disease is restricted to a solitary lesion, its neoplastic nature must be confirmed by histology or cytology. Cytology cannot be the only pathologic criteria to confirm clear cell RCC, but can be used in a patient with histologically confirmed clear cell RCC to confirm that metastatic disease is neoplastic in nature.
  • Must have measurable disease, i.e. presenting with at least one measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST). A measurable lesion is defined as a lesion that can be accurately measured in at least one dimension with the longest diameter ≥ 20 mm using conventional techniques, or ≥ 10 mm with spiral CT scan.
  • Note: Patient should be excluded if all baseline measurable lesions are within previously irradiated areas.
  • Note: A patient must complete all the baseline disease assessments in order to be eligible. Baseline head, chest, abdominal and pelvic CT or MRI scans must be performed within 2 weeks prior to the first dose of study medication; baseline bone scan must be performed within 3 weeks of the first dose of study medication.
  • Patients who have received only one prior systemic treatment for locally advanced or metastatic RCC with documented disease progression or documented treatment discontinuation due to unacceptable toxicity. This first-line systemic treatment must be cytokine based.
  • Note: The first-line cytokine-based treatment can be interleukin-2 (IL-2) or interferon-α (INFα) monotherapy, IL-2 in combination with INF-α, IL-2 and/or INF-α in combination with chemotherapy, hormonal or other therapies excluding agents targeting angiogenesis pathways. Agents in a combination regimen can be given sequentially if the treatment sequence is pre-determined and the patient does not fail one agent prior to starting another.
  • Note: Prior adjuvant or neo-adjuvant therapies are permitted excluding any agents that target vascular endothelial growth factor (VEGF) or VEGF receptors. The adjuvant/neo-adjuvant therapies should not be considered as first-line systemic treatment for advanced RCC.

Or,

  • Patients who have received no prior systemic therapy for advanced/metastatic RCC can be enrolled if under any of the following circumstances:
  • Patients who live in countries or regions where there is no established standard first-line therapy for advanced/metastatic RCC or where there are barriers to the access of established therapies such as sunitinib, sorafenib, IFNα or IL-2.
  • Patients who live in countries or regions where IL-2 or INF-α has been approved for the treatment of advanced/metastatic RCC, however, these agents are generally not recognized by the local clinical community as a standard treatment for advanced/metastatic RCC, or where the physician and the patient have determined that the available cytokine therapies are not an acceptable therapeutic option.
  • Patients who have recurred following prior adjuvant or neo-adjuvant cytokine therapy for RCC are eligible to participate without receiving a first-line systemic treatment for locally advanced or metastatic RCC. These patients should be stratified as the first-line population.
  • Male or female ≥ 18 years of age.
  • A woman is eligible to participate in the study if she is of:
  • Non-childbearing potential (i.e., physiologically incapable of becoming pregnant), including any female who:
  • Has had a hysterectomy,
  • Has had a bilateral oophorectomy (ovariectomy),
  • Has had a bilateral tubal ligation,
  • Is post-menopausal (total cessation of menses for ≥1 year).
  • Childbearing potential, has a negative serum pregnancy test within 2 weeks of the first dose of study medication, and agrees to use adequate contraception. GSK acceptable contraceptive methods, when used consistently and in accordance with both the product label and the instructions of the physician, are as follows:
  • An intrauterine device with a documented failure rate of less than 1% per year.
  • Vasectomized partner who is sterile prior to the female patient's entry and is the sole sexual partner for that female.
  • Complete abstinence from sexual intercourse for 14 days before exposure to investigation product, through the clinical trial, and for at least 21 days after the last dose of investigational product.
  • Double-barrier contraception (condom with spermicidal jelly, foam suppository, or film; diaphragm with spermicide; or male condom and diaphragm with spermicide).
  • Oral contraceptives are not reliable due to the potential for drug-drug interactions.
  • A man with a female partner of childbearing potential is eligible to enter and participate in the study if he is abstinent or uses a barrier method of contraception during the study.
  • Eastern Cooperative Oncology Group Performance Status (ECOG PS) 0 or 1
  • Adequate baseline organ function defined as:
  • Hematologic function:

Absolute Neutrophil Count (ANC) ≥1 x 10^9/L Hemoglobin ≥ 9 g/dL Platelet ≥75 x 10^9/L

  • Hepatic function:

Total bilirubin ≥ 1.5 x Upper Limit of Normal (ULN) Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) ≥ 2 x ULN

  • Renal function:

Calculated creatinine clearance≥30 mL/min [See Section 14.6 Appendix 6] and

≥Urine protein is 0, trace, or +1 determined by dipstick urinalysis, or < 1.0 gram determined by 24-hour urine protein analysis.

  • Note: A patient should first be screened with dipstick urinalysis. If urine protein is ≥2+, then a 24-hour urine protein must be assessed and patient will be excluded if 24-hour urine protein is≥ 1.0 gram.
  • Corrected serum calcium level within normal range per local clinical laboratory standard.

Note: Patients with hypercalcemia should be treated until the corrected serum calcium level reaches the normal range.

  • At least 4 weeks must have elapsed since the last surgery and 2 weeks must have elapsed since radiotherapy or the last systemic cytokine therapy.
  • Complete recovery from prior surgery, and/or reduction of all AEs to Grade 1 from prior systemic therapy or radiotherapy.
