Study of the Anti-angiogenesis Agent AG-013736 in Patients With Metastatic Thyroid Cancer

Phase 2

Completed

Conditions: Thyroid Neoplasms

Interventions: Drug: AG013736

Registration Number: NCT00094055

Lead Sponsor: Pfizer

Brief Summary: This is a Phase 2 study being conducted at multiple centers in the United States. Patients having thyroid cancer that has spread to other parts of the body (i.e., metastatic) are eligible to participate. Patients must have disease that was not controlled by previous treatment with radioactive iodine (131I) or not be good candidates for such treatment. The purpose of the study is to test whether the angiogenesis inhibitor AG-013736 is an effective treatment for metastatic thyroid cancer as shown by the number of patients in the study who experience significant and durable tumor shrinkage.

Detailed Description: Not available

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 60

Inclusion Criteria

Histologically documented thyroid cancer with metastases.
Failure of radioactive iodine (131I) to control the disease or radioactive iodine (131I) is not an appropriate therapy (e.g. due to lack of iodine uptake by the tumor)

Exclusion Criteria

Central lung lesions involving major blood vessels (arteries or veins).(Central lesions that maintain the structural integrity of vessels have the potential to bleed if the tumor lesion undergoes necrosis. MRI or CT angiography should be used in any case where there is any question as to whether blood vessels are involved.)
Patients with a history of hemoptysis

Study & Design

Study Type: INTERVENTIONAL

Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
Percentage of Participants With Objective Response (OR)	Baseline until the date of first documented progression or discontinuation from the study due to any cause, assessed every 8 weeks up to 206 weeks	Percentage of participants with objective response based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). Confirmed response are those that persist on repeat imaging study at least 4 weeks after initial documentation of response. CR are defined as the disappearance of all lesions (target and/or non target). PR are those with at least 30 percent (%) decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.

Secondary Outcome Measures

Name	Time	Method
Progression-Free Survival (PFS)	Baseline to disease progression or death due to any cause, assessed every 8 weeks up to 206 weeks	Time in days from start of study treatment to first documentation of objective tumor progression or death due to any cause. PFS was calculated as (first event date minus the date of first dose of study medication plus 1). Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease \[PD\]), or from adverse event (AE) data (where the outcome was "Death").
Duration of Response (DR)	Baseline to disease progression or discontinuation from study due to any cause, assessed every 8 weeks up to 206 weeks	Time in days from the first documentation of objective tumor response to objective tumor progression or death due to any cause. Duration of tumor response was calculated as the date of the first documentation of objective tumor progression or death due to cancer minus the date of the first CR or PR that was subsequently confirmed plus 1. DR was calculated for the subgroup of participants with a confirmed objective tumor response.
Overall Survival (OS)	Baseline to death due to any cause or at least 1 year after the initial dose for the last treated participant	Time in days from the start of study treatment to date of death due to any cause. OS was calculated as the death date minus the date of first dose of study medication plus 1. Death was determined from AE data (where outcome was death) or from follow-up contact data (where the participant current status was death). For participants who were alive, overall survival was censored at the last contact.
