Cabozantinib S-malate in Treating Patients with Metastatic Pheochromocytomas or Paragangliomas That Cannot Be Removed by Surgery

This pilot phase II trial studies how well cabozantinib s-malate works in treating patients with pheochromocytomas or paragangliomas that have spread from the primary site to other places in the body and cannot be removed by surgery. Cabozantinib s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking the growth of new blood vessels necessary for tumor growth.

PRIMARY OBJECTIVES:

I. To estimate best overall response rate in patients with measurable disease determined by computed tomography (CT) or magnetic resonance imaging (MRI).

SECONDARY OBJECTIVES:

I. To estimate progression-free survival at 1-year. II. To correlate blood pressure control and change/discontinuation of antihypertensive medications with tumor responses.

III. To correlate symptomatology evaluation by the MD Anderson Symptom Inventory (MDASI) with tumor responses.

IV. To correlate plasma metanephrines and chromogranin A with tumor responses. V. To correlate plasma C-reactive protein and interleukin-6 with symptoms and tumor responses.

VI. Toxicity assessment by the Common Terminology Criteria for Adverse Events (CTCAE).

VII. To correlate both c-MET expression by immunohistochemistry (IHC) as well as MET amplification by fluorescence in situ hybridization (FISH) in archived samples and correlate these biomarkers with overall prognosis and responsiveness to cabozantinib (cabozantinib s-malate).

EXPLORATORY OBJECTIVES:

I. Best overall response rate in patients with bone metastases only (8 patients) as determined by fludeoxyglucose F 18 positron emission tomography/computed tomography (FDG-PET/CT).

II. FDG-PET/CT maximum standard uptake value (SUVmax), advanced volumetric measures including peak standard uptake value (SUVpeak), metabolic tumor volume (MTV), and total lesion glycolysis (TLG).

III. Time to skeletal related events. IV. Incidence of skeletal related events at 4 months and one year. V. Markers of bone turnover (bone specific alkaline phosphatase and C-terminal telopeptide \[CTx\]).

OUTLINE:

Patients receive cabozantinib s-malate orally (PO) once daily (QD) on days 1-28. Courses repeat every 4 weeks through week 24 and then every 8 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30-37 days.
