Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Participants are assigned to one of two groups (ARM A vs ARM B) in parallel for the duration of the study.
Primary purpose: TREATMENT

Brief summary: This phase II open label trial randomized patients who completed the induction with nivolumab plus ipilimumab without complete response or progressive disease will be randomized 1:1 to receive axitinib in addition to nivolumab (Arm A) or continue with nivolumab alone (Arm B).Treatment will be continued until progression of disease, unacceptable toxicity, patient's refusal, or physician decision whichever occurred first.

Detailed description: The present study aims to demonstrate if the addition of axitinib to nivolumab maintenance after nivolumab plus ipilimumab induction can improve the rate of response considering that the incidence of partial response was 32% and 51% in Checkmate214 and Keynote426 trials respectively.

This study requires 106 patients to show an improvement from 30% to 50% of the incidence of partial responses with a power of 80%, and alpha-error 0.10 (one-side p).

Assuming a drop out of 10%, the final estimated number to enroll should be 118 (59 in arm A and 59 in arm B).

Eligibility criteria: Inclusion Criteria:

1. Histologically or cytologically confirmed advanced RCC with predominantly clear-cell subtype and candidate to receive nivolumab after nivolumab plus ipilimumab induction as per standard clinical practice.
2. Completion of the induction of nivolumab and ipilimumab without toxicity ≥ G2 and no complete response or progressive disease.
3. Male or female subjects aged ≥ 18 years
4. Available tumor tissue sample.
5. At least one measurable lesion as defined by Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1.
6. Eastern Cooperative Oncology Group performance status 0 or 1.
7. Adequate organ and bone marrow function based upon meeting all of the following laboratory criteria within 10 days before the start of treatment:

   1. Absolute neutrophil count (ANC) ≥ 1500/mm3 (≥ 1.5 GI/L)
   2. Platelets ≥ 100,000/mm3 (≥ 100 GI/L).
   3. Haemoglobin ≥ 9 g/dL (≥ 90 g/L).
   4. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \< 3.0 × upper limit of normal.
   5. Total bilirubin ≤ 1.5 × the upper limit of normal. For subjects with Gilbert's disease ≤ 3 mg/dL (≤ 51.3 µmol/L).
   6. Serum creatinine ≤ 2.0 × upper limit of normal or calculated creatinine clearance ≥ 30 mL/min (≥ 0.5 mL/sec) using the Cockroft-Gault.
8. Capable of understanding and complying with the protocol requirements and must have signed the informed consent document.
9. Sexually active fertile subjects and their partners must agree to use medically accepted methods of contraception (e.g., barrier methods, including male condom, female condom, or diaphragm with spermicidal gel) during the course of the study and for 5 months after the last dose of study treatment.
10. Female subjects of childbearing potential must not be pregnant at screening. Females of childbearing potential are defined as premenopausal females capable of becoming pregnant (i.e., females who have had any evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy). However, women who have been amenorrhoeic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antioestrogens, low body weight, ovarian suppression or other reasons.

Exclusion Criteria:

1. Prior treatment with systemic therapy for advanced RCC with the exclusion of the induction of nivolumab and ipilimumab.
2. Prior adjuvant or neoadjuvant therapy
3. Active seizure disorder or evidence of brain metastases, spinal cord compression, or carcinomatous meningitis
4. Diagnosis of any non-RCC malignancy occurring within 2 years prior to the date of the start of treatment except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ of the breast or of the cervix or low-grade prostate cancer with no plans for treatment intervention.
5. Radiation therapy for bone metastasis within 2 weeks, any other external radiation therapy within 4 weeks before the start of treatment. Systemic treatment with radionuclides within 6 weeks before the start of treatment. Subjects with clinically relevant ongoing complications from prior radiation therapy are not eligible.
6. Known brain metastases or cranial epidural disease unless adequately treated with radiotherapy and/or surgery (including radiosurgery) and stable for at least 3 months before the start of treatment. Eligible subjects must be neurologically asymptomatic and without corticosteroid treatment at the time of the start of treatment.
7. Concomitant anticoagulation at therapeutic doses with oral anticoagulants (e.g., warfarin, direct thrombin and Factor Xa inhibitors) or platelet inhibitors (e.g., clopidogrel).
8. In past 6 months: myocardial infarction, uncontrolled angina, coronary/peripheral artery bypass graft, symptomatic congestive heart failure, cerebrovascular accident, or transient ischemic attack.
9. Chronic treatment with corticosteroids or other immunosuppressive agents (with the exception of inhaled or topical corticosteroids or corticosteroids with a daily dosage equivalent ≤ 10 mg prednisone if given for disorders other than renal cell cancer). Subjects with brain metastases requiring systemic corticosteroid are not eligible.
10. The subject has uncontrolled, significant intercurrent or recent illness including, but not limited to, the following conditions:

    I. Cardiovascular disorders:
    1. Symptomatic congestive heart failure, unstable angina pectoris, serious cardiac arrhythmias.
    2. Uncontrolled hypertension defined as sustained BP \> 150 mm Hg systolic or \> 100 mm Hg diastolic despite optimal antihypertensive treatment.
    3. Stroke (including TIA), myocardial infarction, or other ischemic event, or thromboembolic event (e.g., deep venous thrombosis, pulmonary embolism) within 6 months before the start of treatment.

    IV. Cavitating pulmonary lesion(s) or known endobronchial disease manifestation.

    V. Lesions invading major pulmonary blood vessels.

    VI. Other clinically significant disorders such as:

    2. Serious non-healing wound/ulcer/bone fracture.
    3. Malabsorption syndrome.
    4. Uncompensated/symptomatic hypothyroidism.
