Cabozantinib S-malate in Treating Patients With Neuroendocrine Tumors Previously Treated With Everolimus That Are Locally Advanced, Metastatic, or Cannot Be Removed by Surgery
This randomized phase III trial studies cabozantinib S-malate to see how well it works compared with placebo in treating patients with neuroendocrine tumors previously treated with everolimus that have spread to nearby tissues or lymph nodes, have spread to other places in the body, or cannot be removed by surgery. Cabozantinib S-malate is a chemotherapy drug known as a tyrosine kinase inhibitor, and it targets specific tyrosine kinase receptors, that when blocked, may slow tumor growth.
Randomized, Double-Blinded Phase III Study of CABozantinib Versus Placebo IN Patients With Advanced NEuroendocrine Tumors After Progression on Everolimus (CABINET)
- To determine whether cabozantinib S-malate (cabozantinib) can significantly improve progression-free survival (PFS) compared to placebo in patients with advanced pancreatic neuroendocrine tumors (NET) whose disease has progressed after treatment with everolimus.
II. To determine whether cabozantinib can significantly improve progression-free survival (PFS) compared to placebo in patients with advanced carcinoid tumors whose disease has progressed after treatment with everolimus.
- To determine whether cabozantinib can significantly improve overall survival (OS) compared to placebo in patients with advanced pancreatic NET whose disease has progressed after treatment with everolimus.
II. To determine whether cabozantinib can significantly improve overall survival (OS) compared to placebo in patients with advanced carcinoid tumors whose disease has progressed after treatment with everolimus.
III. To evaluate safety and tolerability of cabozantinib versus placebo in patients with advanced pancreatic NET using Common Terminology Criteria for Adverse Events (CTCAE) and Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE).
IV. To evaluate safety and tolerability of cabozantinib versus placebo in patients with advanced carcinoid tumors using CTCAE and PRO-CTCAE.
- To evaluate the overall radiographic response rate of cabozantinib versus placebo in patients with advanced pancreatic NET whose disease has progressed after treatment with everolimus.
VI. To evaluate the overall radiographic response rate of cabozantinib versus placebo in patients with advanced carcinoid tumors whose disease has progressed after treatment with everolimus.
- Results of the primary analysis will be examined for consistency, while taking into account the stratification factors and/or covariates of baseline quality of life (QOL) and fatigue.
QUALITY OF LIFE SUBSTUDY OBJECTIVES:
- To compare overall quality of life, disease-related symptoms, and other domains between the two treatment groups (cabozantinib versus [vs.] placebo) within each cohort of patients (pancreatic NET vs. carcinoid tumor). (Quality of Life Substudy Objective - A021602-HO1)
POPULATION PHARMACOKINETICS SUBSTUDY OBJECTIVES:
- To describe the population pharmacokinetic and exposure-response relationships of cabozantinib in patients with advanced neuroendocrine tumors.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive cabozantinib S-malate orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive placebo PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 12 weeks until disease progression or start of new anticancer therapy, and then every 6 months until 8 years after registration.
