Patients receive cabozantinib-s-malate PO daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Cabozantinib S-malate

Laboratory Biomarker Analysis

Manisha Shah

This phase II trial studies how well cabozantinib-s-malate works in treating patients with thyroid cancer that does not respond to treatment. Cabozantinib-s-malate may stop the growth of thyroid cancer by blocking some of the enzymes needed for cell growth. Cabozantinib-s-malate may also stop the growth of thyroid cancer by blocking blood flow to the tumor.

PRIMARY OBJECTIVES:

I. The objective response rate, defined as the proportion of patients who have had a partial response (PR) or complete response (CR) within the first 6 months after initiation of therapy with cabozantinib (cabozantinib-s-malate).

SECONDARY OBJECTIVES:

I. To assess duration of objective response, progression-free survival and overall survival.

II. To assess tolerability and adverse events of cabozantinib as a 2nd line therapy in patients with differentiated thyroid cancer (DTC).

TERTIARY OBJECTIVES:

I. To assess effect of cabozantinib on serum tumor marker thyroglobulin and its correlation with overall response rate.

II. To assess response of cabozantinib in bone metastasis (bone metastasis-specific progression free survival) as evaluated by pre- and on-study functional imaging such as bone scan, fludeoxyglucose F 18 (18F-FDG) positron emission tomography (PET) scan and/or 18F sodium fluoride (NaF) PET scan.

III. To assess effect of cabozantinib on serum and urinary markers of bone turnover and its correlation with response to bone metastasis.

IV. To assess predictors of response by performing tumor genotype studies (e.g. v-raf murine sarcoma viral oncogene homolog B \[BRAF\], rat sarcoma \[RAS\], phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha \[PIK3CA\], mitogen-activated protein kinase 1 \[MAP2K1\], v-akt murine thymoma viral oncogene homolog 1 \[AKT1\], mesenchymal-epithelial transition \[MET\], rearranged in transformation \[RET\]/papillary thyroid carcinoma \[PTC\] rearrangement) in archived tumor tissue.

V. To assess predictors of response by assessing baseline expression levels of vascular endothelial growth factor (VEGF), phosphorylated vascular endothelial growth factor receptor (pVEGFR), phosphorylated mitogen-activated protein kinase 1 (pERK), phosphorylated AKT1 (pAKT) and/or total met proto-oncogene (MET) by immunohistochemistry in archived tumor tissue.

OUTLINE:

Patients receive cabozantinib-s-malate orally (PO) daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 4 weeks and then every 3 months for 1 year.

Cabozantinib-S-Malate in Treating Patients With Refractory Thyroid Cancer

Phase II Study of Cabozantinib in Patients With Radioiodine-Refractory Differentiated Thyroid Cancer Who Progressed on Prior VEGFR-Targeted Therapy

Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR

Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

These baseline levels will be quantitatively summarized and graphically explored, in particular in terms of how they relate to clinical outcomes of interest. Analyses exploring differences in these angiogenic and correlative markers in relation to clinical outcomes will be largely hypothesis-generating. With limited numbers of patients patterns of difference will primarily be looked for using graphical analyses; these can include plots of these marker levels in relation to clinical outcomes to identify potential patterns of interest.

The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns. Tolerability of the regimens will be assessed through assessing the number of patients who required dose modifications and/or dose delays. In addition, the proportion of patients who go off treatment due to adverse reactions or even those who refuse further treatment for lesser toxicities that inhibit their willingness to continue participation on the trial will be captured.

Side-by-side boxplots will be used to assess possible differences in this change between responders and non-responders, and scatterplots can assess the influence of baseline thyroglobulin levels on these measures of change.

Exelixis

National Cancer Institute (NCI)

The National Cancer Institutes (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 was utilized for Adverse event reporting.

Patients receive cabozantinib-s-malate PO daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Cabozantinib S-malate: Given PO

Laboratory Biomarker Analysis: Correlative studies

Treatment (Cabozantinib-s-malate)

Patients receive Cabozantinib 60mg PO QD with dose escalation to 80mg QD or dose reduction to 40mg daily or 20mg. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
