Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
I. To define the response rate associated with ivonescimab in patients with high-risk, localized renal cell carcinoma (RCC) planned for nephrectomy.
SECONDARY OBJECTIVES:
I. To define toxicity associated with ivonescimab in this setting. II. To define the feasibility of surgery following systemic therapy with ivonescimab.
III. To determine the pathologic response rate following ivonescimab. IV. To characterize KIM-1 expression before and after ivonescimab. V. To determine survival outcomes following ivonescimab.
EXPLORATORY OBJECTIVES:
I. To characterize the expression of validated genomic signatures (including those derived from IMmotion151) in baseline biopsy and nephrectomy tissue (i.e., before and after therapy with ivonescimab).
II. To evaluate patient-reported quality of life using the FKSI-23 instrument at baseline, pre-surgery, and at post-surgical follow-up time points.
OUTLINE:
Patients receive ivonescimab intravenously (IV) over 60-120 minutes on day 1 of each cycle. Cycles repeat every 3 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. Between 4-10 weeks after completion of ivonescimab treatment, patients then undergo standard of care (SOC) nephrectomy. Patients also undergo echocardiogram (ECHO) during screening, biopsy prior to treatment start, and computed tomography (CT) and blood sample collection throughout the study.
After completion of study treatment, patients are followed every 12 weeks for a total of 2 years and then periodically at the discretion of the investigator.

Treatment (ivonescimab)
Patients receive ivonescimab IV over 60-120 minutes on day 1 of each cycle. Cycles repeat every 3 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. Between 4-10 weeks after completion of ivonescimab treatment, patients then undergo SOC nephrectomy. Patients also undergo ECHO during screening, biopsy prior to treatment start, and CT and blood sample collection throughout the study.

* Creatinine clearance (CrCL) ≥ 50 mL/min using the Cockcroft-Gault formula or estimated glomerular filtration rate (eGFR) value ≥ 60 mL/min using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation (adjustment by body surface area \[BSA\] is not required for eGFR)
* Urine protein \< 2+ or 24-hour urine protein quantification \< 1.0 g
* Serum total bilirubin (TBIL) ≤ 1.5 × upper limit of normal (ULN); For patients with liver metastases or confirmed/suspected Gilbert syndrome, TBIL ≤ 3 × ULN
* Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN; For patients with liver metastases, AST and ALT ≤ 5 × ULN
* Coagulation: Prothrombin time (PT) or international normalized ratio (INR) ≤ 1.5 × ULN, and partial prothrombin time (PTT) or activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN (unless abnormalities are unrelated to coagulopathy). This applies only to patients who are not on therapeutic anti-coagulation. Patients receiving therapeutic anti-coagulation should be on a stable dose
* Female patients of childbearing age must have negative serum pregnancy test results before enrollment or per region-specific guidance documented in the informed consent and a negative urine pregnancy test on the day of first dose prior to dosing
* Female patient of childbearing potential having sex with an unsterilized male partner must agree to use a highly effective method of contraception from the beginning of screening until 90 days after the last dose of the ivonescimab
* Unsterilized male patients having sex with a female partner of childbearing potential, or a pregnant or breastfeeding partner must agree to use barrier contraception (male condom) for the duration of the treatment period until 90 days after the last dose of ivonescimab. Male patients with female partners of childbearing potential must have the female partner agree to use at least 1 form of highly effective contraception for the duration of the treatment period until 90 days after the last dose of ivonescimab
