This is a Phase I trial for safety and preliminary efficacy of the combination of axitinib and SLM for adult patients with advanced metastatic CCRCC. This will be a two part study consisting of a dose escalation and expansion study.~Dose-Escalation Part 1 (6-12 patients): THIS PHASE HAS BEEN COMPLETED. SLM will be given twice daily for 14 days followed by once daily dosing in combination with axitinib 5 mg twice daily with titration according to package insert in patients with advanced renal cell carcinoma. Treatment will continue until disease progression or unacceptable toxicity. The MTD was determined to be 4000 mcg SLM.~Expansion Part 2: In this phase (approximately 19 patients), will be treated at the maximum tolerated dose (MTD) of SLM determined in the Escalation Part 1. It will be given orally twice daily for 14 days, followed by once daily dosing in combination with axitinib 5 mg twice daily with titration according to package insert in patients with advanced renal cell carcinoma. Treatment will continue until disease progression or unacceptable toxicity.~A pilot group of 10 subjects will have SLM dose calculated based on patients' BSA to characterize the dose-concentration relationship and estimate the effective administered dose of selenium necessary to achieve the target blood concentration range informed by preclinical data.
This is a Phase I/II trial for safety and preliminary efficacy of the combination of axitinib and selenomethionine (SLM) for adult patients with advanced metastatic clear cell renal cell carcinoma (CCRCC). This will be a two part study consisting of a dose escalation and expansion study.~In addition, a pilot group of 10 subjects will have SLM dose calculated based on patients' body surface area (BSA) to characterize the dose-concentration relationship and estimate the effective administered dose of selenium necessary to achieve the target blood concentration range informed by preclinical data.
