Inclusion Criteria: Patient must have ECOG PS of ≤ 2 within 28 days of C1D1. Age ≥ 18 years old at the time of informed consent. Patient must have histological confirmation of renal carcinoma with clear cell component including advanced RCC (not amenable to curative surgery or radiation therapy) or metastatic RCC. Patient must have measurable disease by CT or MRI per RECIST 1.1 criteria. Radiated lesions cannot be used as measurable lesions unless there is clear evidence of progression. Patient must have defined IMDC risk categorization of either favorable, intermediate or poor based on clinical variables of increased risk (below). No risk factors (0) = favorable risk 1-2 risk factors = intermediate risk ≥ 3 risk factors = poor risk NOTE: Patients with all IMDC risk factors are eligible, but will be stratified according to IMDC risk, and initial analysis will be based on the IMDC intermediate and poor risk patients. IMDC Risks: KPS less than 80% Less than 1 year from diagnosis including original localized disease to randomization(if applicable) Hemoglobin less than the lower limit of normal Corrected calcium concentration greater than 10 mg/dL ANC greater than the ULN Platelet count greater than the ULN Patient must have either a formalin-fixed, paraffin-embedded (FFPE) tissue block or unstained tumor tissue sections, obtained from a metastatic lesion, preferably within 3 months or no more than 12 months with an associated pathology report. This tissue must be identified prior to registration. Confirmation of sufficient archival tissue must be obtained after informed consent and the tissue must be shipped to the appropriate lab by end of Cycle 2. Biopsies should be excisional, incisional, or core needle. Fine needle aspiration is unacceptable for submission. Biopsies of bone lesions that do not have a soft tissue component are also unacceptable for submission. This sample is required to be eligible for the trial.

Exclusion Criteria: Prior adjuvant or systemic therapy for RCC. Prior treatment with an anti-PD1 or anti-PDL1 agent, anti-CTLA4 antibody or a VEGFR TKI or anti-VEGF antibody including in the adjuvant setting. Radiotherapy within 2 weeks prior to Cycle 1 Day 1. Expected to require any other form of systemic or localized antineoplastic therapy while on trial (including maintenance therapy with another agent, radiation therapy, and/or surgical resection). Currently known active and definitive CNS metastases. Patients who have treated brain metastases (with either surgical resection or stereotactic radiosurgery (SRS)) may be eligible. Patients must not have taken any steroids ≤ 2 weeks prior to randomization for the purpose of managing their brain metastases. Repeat imaging after SRS or surgical resection is not required so long as baseline MRI is within 4 weeks of registration. Patients with multiple brain metastases treated with SRS (with or without WBRT), are not excluded. Patients with definitive CNS metastases treated with only WBRT are ineligible. Patients with potential CNS metastases that are too small for treatment with either SRS or surgery (e.g. 1-2 mm) and/or are of uncertain etiology are potentially eligible, but need to be discussed with and approved by the sponsor-investigator.

Any condition including medical, emotional, psychiatric, or logistical that, in the opinion of the Investigator, would preclude the participant from adhering to the protocol or would increase the risk associated with study participation or study treatment administration or interfere with the interpretation of safety results. Receipt of a live/attenuated vaccine within 30 days of first study treatment. The use of inactivated seasonal influenza vaccines (eg, Fluzone®) will be permitted on study without restriction.

Arm Description

Arm A subjects will receive 2 cycles of induction treatment with each cycle lasting 6 weeks. Cycle 1 will consist of botensilimab 75mg IV in combination with balstilimab 450mg IV on Day 1 and Day 22. Cycle 2 will consist of balstilimab 450mg IV ONLY on Day 1 and Day 22. Botensilimab will NOT be given in Cycle 2. Subjects will receive 7 cycles of maintenance treatment with each cycle lasting 12 weeks. Cycles 3 and 4 will consist of botensilimab 75mg IV on Day 1 in combination with balstilimab 450mg IV on Day 1, 22, 43 and 64.

Arm B subjects will receive 2 cycles of induction treatment with each cycle lasting 6 weeks. Cycle 1 and 2 will consist of ipilimumab 1 mg/kg IV and nivolumab 3 mg/kg on Day 1 and 22. Subjects will receive 7 cycles of maintenance treatment with each cycle lasting 12 weeks. Nivolumab 480mg IV will be given on Day 1, 29 and 57 of each cycle (every 4 weeks).

Outcomes

Primary Outcome Measures

Determine the objective response rate (ORR) of botensilimab + balstilimab in patients with treatment naïve metastatic ccRCC relative to the ORR of patients treated with ipilimumab + nivolumab.
ORR is defined as the proportion of the subjects in the analysis population who have a CR or PR per RECIST 1.1.

Secondary Outcome Measures

Determine Duration of response (DOR) for patients who have a CR or PR
DOR is defined as the time from first documented evidence of CR or PR per RECIST 1.1 until disease progression based on RECIST 1.1 or death due to any cause, whichever occurs first.
Determine the 12- & 24-month landmark progression free survival (PFS)
PFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 or death due to any cause, whichever occurs first.
Determine treatment free survival (TFS)
TFS will be assessed based on the area between two time to event KM curves. 1. time from study treatment initiation to study treatment discontinuation (last dose + dosing interval). 2. Time from study initiation to initiation of subsequent systemic anti-cancer treatment or death. Time on or off treatment with Grade 3 or greater treatment related toxicities per CTCAE v5 will be determined as the area between study initiation and toxicity start and study initiation and Grade 3 toxicity ending.
Determine the safety of botensilimab + balstilimab relative to ipilimumab + nivolumab

5. Study Description

Brief Summary
This study is a randomized, open label, multicenter Phase II trial to evaluate the efficacy and safety of botensilimab (a novel Fc enhanced Tree depleting anti-CTLA4) and balstilimab (a novel anti-PD1) relative to ipilimumab and nivolumab in treatment naïve patients with metastatic ccRCC. The study will plan to enroll 120 eligible patients randomized in a 2:1 fashion to Arm A and Arm B. Patients in all IMDC Risk Groups are included. This study utilizes a Simon's two stage design which is described in the protocol. Patients randomized to Arm A will receive botensilimab in combination with balstilimab. Patients randomized to Arm B will receive ipilimumab in combination with nivolumab. Study treatment on both arms will continue until toxicity, disease progression or a maximum of 96 total weeks (12 weeks induction, 84 weeks maintenance).
