Axitinib with or without Anti-OX40 Antibody PF-04518600 in Treating Patients with Metastatic Kidney Cancer

Trial Status: Active

This randomized phase II trial studies how well axitinib with or without anti-OX40 antibody PF-04518600 work in treating patients with kidney cancer that has spread to other parts of the body. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as anti-OX40 antibody PF-04518600, use substances made from living organisms that may stimulate the immune system in different ways and stop tumor cells from growing. Giving axitinib with or without anti-OX40 antibody PF-04518600 may work better in treating patients with kidney cancer.

  • Major surgery less than 6 weeks prior to the first dose of study drug; minor surgery less than 4 weeks prior to the first dose of study drug; insertion of vascular access device >= 7 days prior to 1st dose of study drug is allowed
  • Anti-cancer therapy or palliative, focal radiation therapy less than 14 days prior to the first dose of study drug
  • Presence of toxicities attributed to prior therapy other than alopecia that have not resolved to grade 1 (National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] version 4) or baseline before administration of study drug
  • History of grade 3 or higher immune-mediated adverse event including AST/ALT elevations and cytokine release syndrome related to prior immune-modulatory therapy (eg, checkpoint inhibitors, co-stimulatory agents etc.); endocrinopathies and skin rash are allowed at the discretion of treating physician; study principal investigator (PI) is available for discussion of individual cases
  • Patients with intolerance to or who have had a severe (>= grade 3) allergic or anaphylactic reaction to antibodies or infused therapeutic proteins, or patients who have had a severe allergic or anaphylactic reaction to any of the substances included in the investigational product (including excipients)
  • Patients with a previous history of anthracycline treatment are excluded
  • Any one of the following currently or in the previous 6 months: * Myocardial infarction * Congenital long QT syndrome * Torsade’s de points * Arrhythmias (including sustained ventricular tachyarrhythmia and ventricular fibrillation), and left anterior hemiblock (bifascicular block); rate controlled atrial fibrillation is allowed. * Unstable angina, coronary/peripheral artery bypass graft * Symptomatic congestive heart failure (congestive heart failure [CHF] New York Heart Association class III or IV) * Cerebrovascular accident, transient ischemic attack or symptomatic pulmonary embolism or other clinical significant episode of thrombo-embolic disease (cases must be discussed in detail with study chair to judge eligibility; anticoagulation [heparin only, no vitamin-K antagonists or factor Xa inhibitors] will be allowed if indicated) * Ongoing cardiac dysrhythmias of NCI CTCAE grade >= 2, atrial fibrillation of any grade, or QT correction using Fridericia's correction formula (QTcF) interval > 470 msec at screening (except in case of right bundle branch block, these cases must be discussed with sponsor’s medical monitor)
  • Other severe acute or chronic medical or psychiatric condition, including recent (within the past year) or active suicidal ideation or behavior, or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study
  • Patients using strong CYP3A4/5 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, and voriconazole) are excluded unless the strong CYP3A4/5 inhibitor agent can be changed

I. To determine whether a statistically significant improvement in progression free survival exists for patients receiving the combination.


I. To determine whether the combination is safe and whether objective response rate (ORR), duration of response (DOR) and overall survival (OS) improve as a result of treatment with combination of axitinib + anti-OX40 antibody PF-04518600 (PF‐04518600 [OX40 Ab]) compared to axitinib + placebo.


I. To determine whether pre and post treatment specimens collected during the trial demonstrate significant changes in tumor microenvironment and enhanced immune response to tumor cells.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive axitinib orally (PO) twice daily (BID) on days 1-14 and anti-OX40 antibody PF-04518600 intravenously (IV) over 60 minutes on day 1 beginning with course 2. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive axitinib as in Arm I and placebo IV on day 1 beginning with course 2. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30, 90, and 180 days.
