Study of 18F-FFNP Breast PET/MRI

About this study

This clinical trial will investigate an estrogen-regulated parameter as an early measure of endocrine therapy response: progesterone receptor (PR) protein with a progestin-based radioligand, 18F-fluorofuranylnorprogesterone (18F-FFNP). The overall purpose of this research is to test the efficacy of 18F-FFNP PET/MRI for predicting response to presurgical endocrine therapy and to determine the quantitative reliability of 18F-FFNP breast PET/MRI in patients with newly diagnosed PR+ primary breast cancer.

Condition: Breast Cancer

Who can join

Age: 18 years and older
Sex: Female only
Healthy volunteers: Not accepted

Inclusion 10

Minimum age: 18 years
Eligible sex: Female
Study condition: Breast Cancer
Postmenopausal status defined by either
prior bilateral oophorectomy
age greater than or equal to 60 years of age
age less than 60 years of age and amenorrheic for 12 or more months in the absence of prior chemotherapy, tamoxifen, toremifene or ovarian suppression and FSH and estradiol in the postmenopausal range per local normal range (Group 2 only)
Diagnosis of biopsy-proven invasive breast cancer measuring at least 1.0 cm in diameter by any imaging modality. Malignancy may be located within the breast, axilla (e.g. metastatic axillary lymph node), or both the breast and axilla
Biopsy-proven PR-positive invasive breast cancer
Definitive surgical excision of the primary tumor planned without neoadjuvant therapy; defined as therapy (chemotherapy, targeted therapy, radiation therapy or endocrine therapy) given to decrease the size of the tumor prior to planned surgery. (Group 2 only)

Exclusion 19

Inability or unwillingness to provide informed consent to the study
HER2-positive breast cancer, as defined by immunohistochemical staining 3+ OR positive by in situ hybridization (Group 2 only)
PR and Ki67 IHC slides or FFPE tissue blocks from clinical breast biopsy not available
Patients who have completed neoadjuvant chemotherapy, endocrine therapy, targeted therapy, surgical resection, or radiation for the current biopsy-proven malignancy (Group 2 only)
Patients who are planning to undergo anastrozole as standard of care neoadjuvant therapy
Patients who are currently taking aromatase inhibitors or ER antagonists (tamoxifen, raloxifene)
Patients with breast expanders
Patients who are pregnant or lactating
Patients with clinical contraindication for use of aromatase inhibitors (AI) while on study as determined by investigator (Group 2 only)
Patients with a contraindication to gadolinium-based contrast agents, including allergy or impaired renal function (per UW Health Guidelines)
Patients with a history of allergic reaction attributable to compounds of similar chemical or biologic composition to 18F-FFNP
Patients with history of allergic reaction to anastrozole (Group 2 only)
Patients in liver failure as judged by the patient's physician
Patients with standard contraindications to MRI (per UW Health Guidelines)
Patients requiring conscious sedation for imaging are not eligible; patients requiring mild, oral anxiolytics for the clinical MRI scan will be allowed to participate as long as the following criteria are met:
The patient has their own prescription for the medication
The informed consent process is conducted prior to the self-administration of the medication.
The patient comes to the research visit with a driver.
Patients unable to lie prone for 45 minutes for imaging
