Clinical Trial Summary

BACKGROUND: For synchronous metastatic renal cell carcinoma (RCC), surgical resection of the primary tumor in the presence of distant metastases has been the standard of therapy for select patients followed by systemic therapy. In the era of TKIs two randomized trials, CARMENA and SURTIME, have questioned the role and timing of surgery in these patients, results point towards no surgery or a deferred approach.

RATIONALE: The antitumor activity of immune checkpoint blockage (ICB) is more potent than other therapy in mRCC. The deferred cytoreductive nephrectomy approach ensures systemic therapy for all patients, avoid systemic treatment delay, and spare surgery in patients with progressive tumors. Current data only point towards a survival benefit for cytoreductive nephrectomy in intermediate risk patients, but not in poor risk patients

HYPOTHESIS: Deferred cytoreductive nephrectomy after initial nivolumab combined with ipilimumab or a TKI/IO-combination will improve OS in patients with synchronous metastatic RCC and ≤3 IMDC risk features

This is an open, randomized, multicenter comparison trial, designed to evaluate the effect of deferred cytoreductive nephrectomy compared with no surgery following initial nivolumab combined with ipilimumab or a TKI-combination, in mRCC patients with IMDC intermediate and poor risk.

Description:

OUTLINE: This is a multicenter trial, patients are stratified according to institution, treatment choice, number of IMDC risk factors, and combined elevated neutrophil-lymphocyte ratio and hyponatremia.

All patients will receive induction checkpoint immunotherapy immediately after inclusion. After 3 months or a total of 4 series of nivolumab combined with ipilimumab or a TKI/IO-combination, the patient will be discussed for resectability at the multidisciplinary meeting (MDT). Whether the patient is eligible for cytoreductive nephrectomy is at the discretion of the urologist at the local MDT. Patients with ≤ 3 IMDC risk factors and deemed suitable for cytoreductive nephrectomy will then undergo randomization. Patients deemed not suitable for surgery or have > 3 IMDC risk features at the 3 month evaluation continue systemic therapy for 3 months, followed by a 2nd evaluation. Patients with ≤ 3 IMDC risk factors and deemed suitable for cytoreductive nephrectomy at 2nd evaluation will then undergo randomization. Patients deemed not suitable for surgery or have > 3 IMDC risk features at the 6 month evaluation continue systemic therapy. Nivolumab may continue until unacceptable toxicity or total treatment length of 2 years from inclusion.

ARM A: Deferred cytoreductive nephrectomy, followed by maintenance nivolumab or a TKI/IO-combination.

ARM B: No surgery, receive maintenance nivolumab or a TKI/IO-combination.

Patients undergo tumor tissue, blood, and stool collection at baseline, 3 and 6 months, for planned translational research.

Eligibility

Inclusion Criteria:

1. Signed written informed consent obtained prior to any study specific procedures.

2. Patient must be willing and able to comply with the protocol.

3. Age =18.

4. Core needle biopsy proven metastatic renal cell carcinoma - all histologic subtypes acceptable.

Patients for which Nivolumab/Ipilimumab or a TKI/IO-combination is considered indicated according to the recommendations by the European Medicines Agency and the national health authorities of participating countries. The prescription of nivolumab/ipilimumab or a TKI/IO-combination in the circumstances of the study is considered as a standard treatment.

8. Females with a negative serum pregnancy test unless childbearing potential can be otherwise excluded (postmenopausal, hysterectomy or oophorectomy) and not lactating.

9. Fertile women of childbearing potential (<2 years after last menstruation) and men must use effective means of contraception (oral contraceptives, intrauterine contraceptive device, barrier method of contraception in conjunction with spermicidal jelly or surgical sterilization).

10. Karnofsky Performance status =70

11. Life expectancy of greater than 4 months.

12. The required laboratory values are as follows:

• Adequate bone marrow function (Leucocytes > 3.0 x 109/l, platelets > 100 x 109/l, hemoglobin > 6.0 mmol/l or > 10.0 g/dL.)

• International normalized ratio (INR) = 1.2 x upper limit of normal (ULN)

• Adequate hepatic function (bilirubin = 1.5 x ULN, ALAT = 2.5 x ULN or = 5 x ULN if liver lesions)

• Adequate kidney function (eGFR > 35 mL/min)

Exclusion Criteria:

1. Prior systemic treatment for mRCC

2. Other cancer within 3 years (except in situ basal cell carcinoma and localised prostate cancer with undetectable PSA).

3. Major surgical procedure, open surgical biopsy, or significant traumatic injury within 28 days prior to enrollment

4. Clinically significant (i.e active) cardiovascular disease for example cerebrovascular accidents (< 6 months before inclusion), myocardial infarction (< 6 months before inclusion), unstable angina, New York Heart Association (NYHA) grade II or greater congestive heart failure.

5. No symptomatic brain metastasis requiring systemic corticosteroids (> 10 mg daily prednisone equivalent)

6. Recent (within the 30 days prior to inclusion) treatment with another investigational drug or participation in another investigational study.

7. Any active or recent history of a known or suspected autoimmune disease or recent history of a condition that require systemic corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive medications, excluding inhaled steroids and topical steroids. Subjects with vitiligo or type I diabetes mellitus or residual hypothyroidism due to autoimmune thyroiditis only requiring hormone replacement, psoriasis not requiring systemic treatment are permitted to enroll.

8. Known hypersensitivity to monoclonal antibodies.

9. Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS).

10. Any positive test for hepatitis B- or C-Virus indicating acute or chronic infection.

11. Oral or i.v. antibiotics administered 14 days prior to initiation of systemic therapy.
