PET/CT in Evaluating Response to Chemotherapy in Patients With Breast Cancer

August 9, 2023 updated by: University of Southern California

Development of an In Vivo Cell Proliferation Marker for PET Assessment of Chemotherapeutic Response in Cancer

This phase I trial studies the side effects of positron emission tomography (PET)/computed tomography (CT) in evaluating response to chemotherapy in patients with breast cancer. Comparing results of diagnostic procedures done before, during, and after chemotherapy may help doctors predict a patient's response to treatment and help plan the best treatment.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

PRIMARY OBJECTIVES: I. Study fludeoxyglucose [18F] 2'-fluoro-5-methyl-1-beta-D-arabinofuranosyluracil-clevudine (FMAU) (fluorine F 18-clevudine ) in 10 patients with known breast cancer to obtain data on safety, circulating metabolite, tumor imaging feasibility, and radiation dosimetry. II. Assess the potential utility of FMAU-PET in the imaging evaluation of chemotherapeutic response in 15 patients with breast cancer. OUTLINE: Patients receive fluorine F18-clevudine intravenously (IV) over 1 minute and then undergo PET/CT scan at baseline. Patients with human epidermal growth factor receptor 2 positive (HER2+) breast cancer also undergo fluorine F 18-clevudine PET/CT scan 2-3 weeks after the first course of treatment and after completion of treatment. After completion of study treatment, patients are followed up at 24 hours.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion criteria for Aim 2:

  • Have been diagnosed with a HER2+ invasive cancer of the breast
  • Scheduled to receive pre-operative therapy with trastuzumab plus chemotherapy as part of standard care

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Change of FMAU-PET score vs. change of Ki-67 from the baseline to post-chemotherapy
Time Frame: Up to 1 year
Up to 1 year
Incidence of adverse events
Time Frame: Up to 24 hours after completion of study treatment
Up to 24 hours after completion of study treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
