Brief summary: Multicenter, single arm, phase II study using a A'Hern single-stage procedure in patients with locally advanced or metastatic papillary renal cell carcinoma (PRCC) in first-line treatment.

Detailed description: Renal cell carcinoma (RCC) accounts for 2-3% of all adult malignancies worldwide, representing the seventh most common cancer in men and the ninth in women. The annual incidence is more than 337 000 cases and around 140 000 persons die every year. Half of patients with RCC are going to develop metastases, either with synchronous metastatic sites (25%) or during the follow up (25%).

Papillary renal cell carcinoma (PRCC) represents 10-15% of RCC and is characterized by a cytogenetic profile distinct from other types of renal cancer. Histologically, PRCC could be separated in 2 distinct subtypes: type 1 and type 2.

Vascular endothelial growth factor (VEGF) is a potent induction factor, playing a central role in angiogenesis and vascular permeability of tumor tissues. It binds to three specific receptors: VEGFR-1, VEGFR-2 and VEGFR-3, which are thus implicated in pathologic angiogenesis, tumor growth and metastatic progression of cancer. Patients with papillary histology demonstrated high expression of VEGF and VEGFR-2, making VEGF-targeted therapy an attractive therapeutic option.

Recently, several studies have been developed to assess VEGF targeted therapy in patients with PRCC, mostly with sunitinib and with poor results (median progression-free survival (PFS) around 6 months).

Axitinib is a potent, selective second-generation inhibitor of all three VEGF receptors. By inhibiting VEGF-mediated endothelial cell proliferation and survival, axitinib inhibits angiogenesis and tumor growth.

In phase II trials, axitinib has shown anti-tumor activity with well-tolerated clinical safety profile in patients with advanced solid tumors, including RCC.

Axitinib has been approved for the second-line treatment of advanced RCC on the basis of the pivotal randomized phase III AXIS trial results. 723 patients were enrolled and randomly assigned to receive axitinib or sorafenib. The median PFS assessed by independent review committee was 6.7 months with axitinib compared to 4.7 months with sorafenib (hazard ratio 0.665; 95% CI 0.544-0.812; one-sided p\<0.0001).

In all studies, the safety analysis showed a good tolerance of axitinib. The most common adverse reactions (occurring in \>20% of treated subjects) were diarrhea, hypertension, fatigue, decreased appetite, nausea, dysphonia and hand-foot skin reaction. Dose discontinuations were reported in 4% of patients with axitinib vs. 8% with sorafenib.

Little clinical data regarding the efficacy of recently developed VEGF targeted therapies in first-line treatment of PRCC is available. To date, there is no standard treatment, and evaluation of efficacy of the new targeted agents is clearly needed.

The purpose of this study is to evaluate the efficacy and safety of axitinib in first-line treatment of patients with papillary renal cell carcinoma.

Axitinib inhibits angiogenesis and vascular permeability in tumor tissues, leading to inhibition of tumor growth.

Axitinib has shown antitumor activity in patients with RCC in phase II and III clinical trials.

VEGF inhibitors are currently used in PRCC treatment, with disappointing results. Axitinib is more potent and selective against the VEGFR family compared with sorafenib and sunitinib in biochemical assays, and could have a similar efficacy with lesser toxicities, therefore may provide a clinical benefit in patients with PRCC.

Eligibility criteria: Inclusion Criteria:

1. Age ≥ 18 years.
2. Metastatic or locally advanced (inoperable) pure type 1 or 2 or mixed PRCC, histologically confirmed by central review: relevant slides \[and blocks if available\] with the initial histology report must be sent for central reading before confirmation of inclusion.
3. No prior systemic treatment for metastatic renal cancer (chemotherapy, immunotherapy, anti-angiogenic drugs, or treatment under evaluation).
4. At least one measurable site of disease as defined by RECIST 1.1 criteria.
5. ECOG performance status of 0, 1.
6. No toxicity \> 1 according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE version 4.0)
7. In case of prior radiation therapy, discontinuation of irradiation for at least 4 weeks before first dose of study treatment. This period can be reduced to at least 1 week in case of radiotherapy in a limited field (\< 10% of the whole body) while no side effects grade ≥ 2 is expected and keeping at least one site for evaluation.
8. Adequate bone marrow, liver and renal function, as defined below:

   * Absolute neutrophil count ≥ 1.5 G/L, platelet count ≥ 100 G/L, and hemoglobin ≥ 9 g/dL),
   * AST/ALT ≤ 3 x upper limit of normal (ULN) (or ≤ 5.0 x ULN if liver metastasis) and total bilirubin ≤ 1.5 x ULN (≤ 2.5 x ULN if liver metastases),
   * Serum creatinine ≤ 2.0 x ULN or creatinine clearance ≥ 50 mL/min according to Cockroft formula or MDRD formula for patients older than 65 years,
9. Absence of proteinuria confirmed by urinary dipstick test. If the dipstick test is ≥ 2+, proteinuria will be quantitated on a complete 24h urine sample (\< 1 g/L of protein/24h sample).
10. Adequate contraceptive methods for fertile female subjects for the whole duration of the study and for 7 days after the last dose of study drug.

    Note: Oral, implantable, or injectable contraceptives may be affected by cytochrome P450 interactions, and are not considered effective for this study.
11. Covered by a medical insurance, in countries where applicable.
12. Written informed consent before any study specific procedures or assessments.

Exclusion Criteria:

1. Prior TKI treatment in adjuvant situation for renal cancer.

   * Disorder of left ventricular function with a LVEF \< 50%,
   * Uncontrolled arterial hypertension under adapted medication: systolic blood pressure ≥ 150 mmHg or diastolic blood pressure ≥ 100 mmHg or both despite appropriate therapy, or patients under 3 antihypertensive therapies at screening,
   * Myocardial infarction, severe angina, or unstable angina within 6 months prior to inclusion,
   * History of serious ventricular arrhythmia (ie ventricular tachycardia or ventricular fibrillation),
   * Cardiac arrhythmias requiring anti-arrhythmic medications (except for atrial fibrillation that is well controlled with anti-arrhythmic medication),
   * Coronary or peripheral artery bypass graft within 6 months of screening.
