C11 AMT Positron Emission Tomography (PET) Imaging in Patients With Metastatic Invasive Breast Cancer

The purpose of this research project is to create images of where and how the amino acid (the building blocks of proteins)Tryptophan is processed in normal and abnormal tissue in the patient's body. Tryptophan is a normal building block of proteins in the body. Sometimes in the case of cancer and other diseases, Tryptophan is processed abnormally, and possible treatments for this abnormality are of great interest because of the potential to improve cancer care.

Radiation: Carbon C 11 alpha-methyltryptophan

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking

Primary Outcome Measures:
  • Occurrence of Detected Changes in Regions of Interest (ROIs) [ Time Frame: Average of 7 weeks ]
    Changes in C-11 AMT uptake and localization (measured by SUV) between baseline and approximately 4 days after initiation of treatment. The primary objective is to determine whether such changes can be detected in regions of interest (ROIs) using PET/CT imaging in patients with metastatic breast cancer enrolled in NCI 8461/ MCC16025. The SUV values in identified regions of interest (ROIs) for each patient will be compared over time between baseline and approximately 4 days after initiation of treatment, and after completion of the protocol treatment. The analysis will be largely exploratory and descriptive as the sample size and study design will likely preclude an adequate/definitive statistical conclusion of SUV values between the two time points.

Secondary Outcome Measures:
  • Number of Participants with Clinical Response [ Time Frame: Average of 7 weeks ]
    Clinical responses based on Response Evaluation Criteria In Solid Tumors [RECIST] criteria, to 1-MT plus the Ad.p53 DC vaccine.

  • Number of Participants with Presence of IDO ImmunoHistoChemistry (IHC) Expression [ Time Frame: Average of 7 weeks ]
    Presence of immuno-modulatory enzyme indoleamine 2,3-dioxygenase (IDO) IHC expression (positive vs. negative as described in NCI 8461/MCC 16025) in the assayed tumor sample.

  • Number of Participants with Immune Response [ Time Frame: Average of 7 weeks ]
    Immune response to the vaccine (by ELISPOT criteria as described in NCI 8461/MCC 16025). The secondary endpoint immunologic response is defined as IFN-γ p53 T cell specific ELISPOT assay count measured, being ≥ 2 SDs above the baseline for a patient.

  • Number of Participants with Adverse Events [ Time Frame: Average of 7 weeks ]
    Examine toxicity data of the protocol treatment according to Common Terminology Criteria for Adverse Events (CTCAE) V4.0.

Arms Assigned Interventions
Experimental: Radiotherapy
AMT positron emission tomography with integrated computed tomography (PET/CT)scanning in metastatic breast cancer patients to identify tumors with increased AMT uptake due to up-regulated IDO expression.
Biological: Adenovirus-p53 transduced dendritic cell vaccine
The Ad.p53 DC vaccine will be injected intradermally (through the skin) into four separate sites. The patient's vaccine will be the same dose throughout the study.
Other Names:
  • Ad.p53 DC
  • vaccine
  • Advexin
Drug: 1-methyl-D-tryptophan
Each treatment cycle is comprised of 21 days. The treatment is continuous with no breaks in between cycles. Patients would not be allowed to take any tryptophan containing supplements while participating on this study.
Other Names:
  • NSC 721782
  • 1-MT
Radiation: Carbon C 11 alpha-methyltryptophan
The experimental examination for this research is the administration by a needle in a vein of Tryptophan labeled with a radioactive tracer (a substance is believed to enhance imaging for easier detection and measurement), Carbon 11, when when the patient has not eaten for five hours. A standard PET/CT scanner is then used to create images of the tracer a few minutes later.
Other Name: radioactive tracer

Detailed Description:

Coordinating Center: Southeast Phase 2 Consortium (SEP2C), Moffitt Cancer Center.

Research participation involves up to three experimental imaging examination visits in radiology: a baseline before the patient starts a cancer treatment, a follow-up a few days later, and a later follow up to see how the treatment may affect normal or abnormal processing of Tryptophan.

The research imaging results will be linked with other evidence of the patient's disease, but will not effect their care.
