Dual Integrin αvβ3 and GRPR Targeting PET Imaging in Breast Cancer Patients

April 21, 2016 updated by: Peking Union Medical College Hospital

68Ga-NOTA-BBN-RGD PET/CT in Breast Cancer Patients

This is an open-label positron emission tomography/computed tomography (PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-NOTA-BBN-RGD in breast cancer patients. A single dose of 111-148 Mega-Becquerel (MBq) 68Ga-NOTA-BBN-RGD will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.

Detailed Description

Gastrin-releasing peptide receptor (GRPR) is a member of the G protein-coupled receptor family of bombesin receptors, which is over-expressed in various types of cancer cells, including prostate cancer, breast cancer, colorectal cancer, pancreatic cancer, glioma, lung cancer, ovarian cancers, endometrial cancers, renal cell cancer and gastrointestinal stromal tumors. BBN(7-14), with the amino acid sequence of Gln-Trp-Ala-Val-Gly-His-Leu-Met-NH2, has been extensively used for the development of molecular probes for the imaging of GRPR. On the other hand, the RGD moiety binds with integrin αvβ3 receptor, also plays an important role in the regulation of tumor growth, angiogenesis, local invasiveness, and metastatic potential in human breast cancer. To target both receptors, a heterodimeric peptide BBN-RGD was synthesized from bombesin(7-14) and c(RGDyK) through a glutamate linker and then labeled with 68Ga. An open-label whole-body PET/ CT study was designed to investigate the safety and dosimetry of 68Ga-NOTA-BBN-RGD and diagnostic performance of 68Ga-NOTA-BBN-RGD PET/CT in breast cancer patients.

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 to 70 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Inclusion Criteria:

  • Neoplasm identified by X-ray, ultrasound or MRI as breast cancer
  • To provide basic information and sign the written informed consent.

Exclusion Criteria:

  • Consisted of conditions of mental illness;
  • Severe liver or kidney disease with serum creatinine > 3.0 mg/dl (270 μΜ) or any hepatic enzyme level 5 times or more than normal upper limit;
