|Official Title:||A Phase II Study of GW 786034 (Pazopanib) in Advanced Thyroid Cancer|
- Confirmed tumor response (differentiated thyroid cancer expanded cohort) [ Time Frame: Up to 3 years ]Tumor response (complete or partial response) as assessed by Response Evaluation Criteria in Solid Tumors criteria noted as objective status on 2 consecutive evaluations at least 8 weeks apart for patients with differentiated thyroid cancer who are thyroglobulin antibody negative.
- Proportion of patients who have achieved an objective response to the study agent [ Time Frame: Up to 3 years ]Objective response as assessed by Response Evaluation Criteria in Solid Tumors criteria.
- Biomarker-based response [ Time Frame: Up to 3 years ]Rates will be summarized assuming they are binomially distributed, and the biomarker levels themselves will be explored both quantitatively and graphically before and after treatment
- Duration of response [ Time Frame: From the date of documentation of partial or complete response until the date of progression or last follow-up (whichever comes first) in the subset of patients with confirmed response, assessed up to 3 years ]Duration of response will be assessed.
- Incidence of toxicity [ Time Frame: Up to 3 years ]Toxicity will be assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns.
- Overall survival [ Time Frame: Time from registration to date of last follow-up or death due to any cause, assessed up to 3 years ]Estimated using the method of Kaplan-Meier.
- Proportion of patients achieving a biochemical response in appropriate tumor markers [ Time Frame: Up to 3 years ]Levels of free VEGF and PDGF will be explored in a graphical manner in pre-treatment and multiple on-treatment samples.
- Proportion of patients in which the radioactive iodine scan have changed from "no uptake" to "any uptake" [ Time Frame: At 6 months (at 3 months for patients with anaplastic thyroid cancer) ]The proportion of patients will be calculated.
- Proportion of patients with differentiated thyroid cancer and medullary thyroid cancer who have not failed treatment at 6 months (3 months for anaplastic thyroid cancer) [ Time Frame: Up to 6 months ]The proportion of patients who have not failed treatment due to disease progression, adverse reactions, refusal for further participation, or who went on to alternate therapy at 6 months (3 months for anaplastic thyroid cancer patients) will be calculated and summarized independently within each of the patient groups. Assuming that the incidence of response is binomially distributed, 90% binomial confidence intervals will also be calculated.
- Time to subsequent therapy [ Time Frame: Up to 3 years ]Estimated using the method of Kaplan-Meier.
- Time to treatment failure [ Time Frame: Time from registration to the date the patient discontinues treatment, assessed up to 3 years ]Estimated using the method of Kaplan-Meier.
- Times to progression [ Time Frame: Time from registration to the date of progression or last follow-up, whichever comes first, assessed up to 3 years ]Time to progression will be estimated using the method of Kaplan-Meier. In addition, the 6-month progression-free rate will be evaluated using the 6-month rates and associated confidence intervals. Competing risk analyses may be done to evaluate time to progression, allowing for going on to alternate treatment or death prior to progression as competing risks.
- Change in blood markers for angiogenesis [ Time Frame: Baseline to up to 3 years ]Blood markers for angiogenesis including levels of free VEGF, free GW786034, and GW786034/VEGF complexes will be evaluated before and during therapy. Changes in these levels will largely be explored in a graphical manner as well as exploring any potential relationships between these levels and clinical outcome such as response or progression-free rate and toxicity incidence.
|Actual Study Start Date:||February 22, 2008|
|Estimated Primary Completion Date:||June 1, 2017 (Final data collection date for primary outcome measure)|
Experimental: Treatment (pazopanib hydrochloride)
Patients receive pazopanib hydrochloride PO QD on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Other: Laboratory Biomarker Analysis
Correlative studiesDrug: Pazopanib Hydrochloride
I. To establish the safety and efficacy of GW786034 (pazopanib hydrochloride) as a therapeutic in patients afflicted with differentiated, medullary and anaplastic thyroid cancers.
I. Assessment of the impact of therapy with GW786034 on serum/plasma vascular endothelial growth factor (VEGF) levels.
II. To explore the potential relationship between changes in thyroglobulin levels and tumor response in patients with advanced differentiated thyroid cancer known to be thyroglobulin antibody negative.
Patients receive pazopanib hydrochloride orally (PO) once daily (QD) 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 6 months or until 3 years after registration.
