Clinical trial: Trebananib And Temsirolimus in Treating Patients With Solid Tumors That Are Metastatic or Cannot Be Removed by Surgery

Summary: This phase I trial studies the side effects and the best dose of trebananib and temsirolimus when given together in treating patients with solid tumors that are metastatic or cannot be removed by surgery. Trebananib may stop the growth of tumor cells by blocking blood flow to the tumor. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving trebananib with temsirolimus may be an effective treatment for solid tumors.

Detailed description: PRIMARY OBJECTIVES:
  I. To determine the recommended phase II dose (RP2D) and safety profile of AMG 386 (trebananib) in combination with temsirolimus in patients with advanced solid tumors.
  SECONDARY OBJECTIVES:
  I. To evaluate pharmacodynamic (PD) effects of both drugs when administered in combination, with the goal of identifying potential predictive and PD markers that need further exploration and validation in future trials.
  II. To explore preliminary anti-tumor activity of both drugs when administered at the RP2D to patients with advanced endometrial cancer, renal cell carcinoma, or carcinoid tumor.
  OUTLINE: This is a dose-escalation study of trebananib.
  Patients receive trebananib intravenously (IV) over 60 minutes and temsirolimus IV over 30-60 minutes on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
  After completion of study treatment, patients are followed up for 30 days.
