PHASE II STARLITE-2 STUDY
Starlite-2 (Phase II, Recruiting)
Study title: A Phase 2 Open-label Study of Nivolumab Combined With Lutetium 177-Labeled Anti-Carbonic Anhydrase IX Monoclonal Antibody Girentuximab in Patients With Clear Cell Advanced Renal Cell Carcinoma
Study description: A Phase II trial evaluating the combination therapy of 177Lu-TLX250 with ipilimumab+nivolumab in metastatic ccRCC patients who have progressed on initial checkpoint inhibitor or TKI therapy. Endpoints include safety and tolerability and objective response rate with this combination.
The purpose of this study is to see if the combination of 177Lu-girentuximab and nivolumab is a safe and effective treatment for advanced clear cell renal cell carcinoma/ccRCC that has the CAIX protein.
PRIMARY OUTCOME MEASURES
Maximal tolerated dose (MTD) of 177Lu-girentuximab [ Time Frame: 24 (+/- 2) weeks ]
To determine the maximal tolerated dose (MTD) of 177Lu-girentuximab when given in combination with nivolumab (safety lead-in)
Overall Response Rate/ORR [ Time Frame: 24 (+/- 2) weeks ]
efficacy of the combination at the MTD of 177Lu-labelled girentuximab in patients with advanced ccRCC as assessed by best ORR by 24 (+/- 2) weeks by Response Evaluation Criteria In Solid Tumors (RECIST v1.1).
ELIGIBILITY: INCLUSION CRITERIA
Locally advanced unresectable or metastatic RCC with a component of clear cell histology i. Archival tumor tissue will be requested from patients who have undergone biopsy or tumor resection as part of routine clinical care prior to study participation to confirm diagnosis. Patients may undergo pre-treatment biopsy during the screening period if archival tissue is insufficient for baseline analysis.Tumor specimen may include nephrectomy or metastatic site specimen.

At least one prior line of systemic therapy, including at least one prior treatment with anti PD-1 or PD-L1antibody
Age ≥18 years
KPS ≥ 70
Adequate performance status and adequate organ function:
ANC ≥ 1500 cells/μL
WBC ≥ 2500/μL
Lymphocyte count ≥ 500/μL
Platelet count ≥100,000/μL (without transfusion within 2 weeks prior to Cycle1, Day 1; thrombopoietic agent use is allowed)
Hemoglobin ≥9.0 g/dL (patients may be transfused or receive erythropoietic treatment to meet this criterion)
AST, ALT, and alkaline phosphatase ≤ 2.5 x ULN, with the following exceptions:
Patients with documented liver metastases: AST and/or ALT ≤ 5 x ULN
Patients with documented liver or bone metastases: alkaline phosphatase ≤ 5 x ULN
Serum bilirubin ≤ 2 x ULNa) Patients with known Gilbert disease who have serum bilirubin level ≤ 3 x ULN may be enrolled.
INR and aPTT ≤ 1.5 x ULNa) This applies only to patients who are not receiving therapeutic anticoagulation; patients receiving therapeutic anticoagulation should be on a stable dose.
Creatinine clearance ≥ 40mL/min, as measured by the Cockcroft-Gault formula.
Women of childbearing potential and men are advised to practice double-barrier contraception until a minimum of 6 months after IV 89Zr-girentuximab or 177Lu-girentuximab administration. Women of childbearing potential are advised to practice double-barrier contraception until a minimum of 5 months after nivolumab.
Signed consent form by the participant or a legally authorized representative (LAR).
