Trebananib With or Without Bevacizumab, Pazopanib Hydrochloride, Sorafenib Tosylate, or Sunitinib Malate in Treating Patients With Advanced Kidney Cancer

PRIMARY OBJECTIVE:

I. To evaluate the overall response rate (complete response [CR] + partial response [PR]) of trebananib (AMG 386) alone and in combination with continuation of previously administered bevacizumab, pazopanib hydrochloride (pazopanib), sorafenib tosylate (sorafenib), or sunitinib malate (sunitinib) in advanced renal cell carcinoma.

SECONDARY OBJECTIVES:

I. To evaluate progression free survival in each arm. II. To evaluate the tolerance and toxicity of AMG 386 alone and in combination with continuation of the prior VEGF targeted agent.

CORRELATIVE OBJECTIVES:

I. To evaluate the association between pretreatment tumor gene expression levels and response to AMG 386 in combination with continuation of the prior VEGF targeted agent.

II. To evaluate the association between single nucleotide polymorphisms (SNPs) in angiogenic genes and response to AMG 386 in combination with continuation of the prior VEGF targeted agent.

III. To compare changes in circulating angiogenic factors in patients treated with AMG 386 monotherapy to those treated with AMG 386 in combination with VEGF-targeted therapy.

IV. To compare expression of angiogenic genes from archival tumor specimens to the expression in biopsy specimens obtained after progression on anti-VEGF therapy.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive trebananib intravenously (IV) over 30-60 minutes on days 1, 8, 15, 22, 29, and 36. Cycles repeat every 42 days in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive trebananib as in Arm I and either bevacizumab IV over 30-90 minutes on days 1, 15, and 29, pazopanib hydrochloride orally (PO) once daily (QD) on days 1-42, sorafenib tosylate PO twice daily (BID) on days 1-42, or sunitinib malate PO QD on days 1-28. Cycles repeat every 42 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 4-8 weeks.

• Patients must be willing to consent to tumor biopsy for research purposes
• Patients should have archival tumor tissue (either unstained slides or tumor blocks) available for retrieval
• The effects of AMG 386 are known to be detrimental to fetal development; for this reason and because inhibitors of angiogenesis as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and 6 months after completion of AMG 386; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 6 months after completion of AMG 386 and bevacizumab, pazopanib, sunitinib, or sorafenib administration
• Ability to understand and the willingness to sign a written informed consent document

Exclusion criteria

• Intolerance of prior treatment with bevacizumab, pazopanib, sorafenib, or sunitinib; Note: subjects who required a dose reduction of pazopanib, sorafenib, or sunitinib during prior therapy MAY be eligible if they tolerated the agent after dose level reduction (to a minimum of dose level -2 as defined in this protocol)
• Central nervous system metastases unless: (1) metastases have been treated and have remained controlled for at least two weeks following treatment, AND (2) patient has no residual neurological dysfunction off corticosteroids for at least one week; a CT or MRI to evaluate for central nervous system (CNS) disease is required for symptomatic patients only

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Pregnant women are excluded from this study because AMG 386, bevacizumab, pazopanib, sorafenib, and sunitinib are inhibitors of angiogenesis with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with AMG 386, breastfeeding must be discontinued if the mother is treated with AMG 386
