Trial summary

Positron Emission Tomography Imaging with 3-Deoxy-3'-[18F]Fluorothymidine (FLT) can selectively identify proliferating and non-proliferating tissues, including tumors. FLT uptake in the tumor is an indirect marker of DNA synthesis activity, which is a target of chemotherapy. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 100 years
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Study population: Women diagnosed with breast cancer whose recommended treatment is neoadjuvant chemotherapy followed by surgical resection.

Who may be able to join

  • Ability to understand and willingness to sign a written informed consent document.
  • Subject must have histologically confirmed breast cancer.
  • Subject must be scheduled to receive neoadjuvant chemotherapy followed by surgery for their standard cancer care. Treatment decisions will be made by the treating surgeon and the medical oncologist.
  • Females at least 18 years of age.
  • Karnofsky at least 60% at time of screening.
  • Life expectancy of greater than 6 months.

  • Subject must have normal organ and marrow function (as defined below) within 30 days of study enrollment:
  • leukocytes at least 3,000/microL
  • absolute neutrophil count at least 1,500/microL
  • platelets at least 100,000/microL
  • total bilirubin Equal or less than 1.0 mg/dl
  • AST(SGOT) no greater than 2.5 X institutional upper limit of normal
  • ALT (SGPT) no greater than 2.5 X institutional upper limit of normal
  • Creatinine Equal or less than 1.4 mg/dl
  • BUN Equal or less than 20 mg /dl
  • The effects of FLT on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. A screening urine hCG will be administered in the Nuclear Medicine to women of childbearing potential before each FLT scan and pregnant women will not be accepted as subjects in this study.

Who cannot join

  • Subjects who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
  • Subject with a Karnofsky score of below 60.
  • Pregnant women are excluded from this study. FLT PET has potential for teratogenic effects. Because there are potentially unknown risks for adverse events in nursing infants secondary to treatment of the mother with FLT, breastfeeding should be discontinued if the mother is imaged with FLT and may not resume for 48 hours after the FLT imaging.
  • Subjects taking nucleoside analog medications such as those used as antiretroviral agents.

About this study

Official title: Positron Emission Mammography With 3'-Deoxy-3'-[18F] Fluorothymidine (FLT PEM) for Evaluation of Response to Neoadjuvant Chemotherapy in Breast Cancer

Positron Emission Tomography Imaging with 3-Deoxy-3'-[18F]Fluorothymidine (FLT) can selectively identify proliferating and non-proliferating tissues, including tumors. FLT uptake in the tumor is an indirect marker of DNA synthesis activity, which is a target of chemotherapy. Our hypothesis is that early change in FLT uptake in tumor with chemotherapy will predict pathological response to neoadjuvant therapy in breast cancer. Tumor uptake of FLT will be imaged and measured with positron emission mammography (PEM), a PET scanner optimized for breast imaging with a significantly improved resolution compared to conventional whole-body PET imaging systems.

    Measured: 20 mintues and 60 minutes post injection

Secondary outcomes (1)
  1. Pathologic tumor response

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Neoplasms, run by University of Iowa at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 11 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Uptake of FLT (SUV) within the tumor (time frame: 20 mintues and 60 minutes post injection). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jul 2016.
