[18F]Fluciclatide PET Imaging of Pazopanib Response

February 27, 2016 updated by: Jin-Sook Ryu, Asan Medical Center

Evaluation of [18F]FluciclatidePositron Emission Tomography For the Prediction of Response to Pazopanib In Patients With Metastatic Renal Cell Carcinoma: An Exploratory Study

Positron emission tomography (PET) is a non-invasive imaging tool for monitoring functional and metabolic responses of biological events with specific radiotracer in vivo. The PET tracer [18F]Fluciclatide is an 18F radiolabeled small peptide containing the RGD (arginine-glycine-aspartate) tri-peptide, which preferentially binds with high affinity to αvβ3 and αvβ5 integrins. αvβ3-integrins are expressed at low levels on epithelial cells and mature endothelial cells but are expressed at high levels on activated endothelial cells in the neo-vasculature of a range of tumors and it also may regulate angiogenesis. If pazopanib acts mainly on active angiogenetic tumors, the quantitative uptake of [18F]Fluciclatide can be used to predict the effect of this antiangiogenic drug. The investigators expected the baseline tumor uptake in [18F]Fluciclatide to be able to predict treatment response, and planned a study of [18F]FluciclatidePET for patients with metastatic RCC who received pazopanib systemic therapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Subjects will receive treatment with pazopanib at a dose of 800 mg orally once daily. [18F]Fluciclatide imagings will be taken 2 times; 1) before systemic therapy (at baseline), 2) at one week after starting of Pazopanib. However, If the target lesion on the baseline PET cannot be discriminated compared to the background activity, the 2nd PET will not be done. Response evaluation by CT will be performed at baseline, at 6 week, at 12 week and every 8 weeks thereafter until the end of treatment. RECIST1.1 criteria for response will be applied. Patient will be treated with Pazopanib until there is disease progression, unacceptable toxicity or withdrawal of patient consent.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers
