The only imaging agent that detects whole-body ER+ lesion status

Biopsy may not always be feasible in metastatic disease, where the BC has spread to distant organs and multiple sites.1,2,7-12 Cerianna PET/CT enables a non-invasive, comprehensive assessment of whole-body ER+ lesion status. 1,4,7,8,13

Unique mechanism of action that detects ER+ lesions*†5

Cerianna is a radiolabeled estrogen analog that is transported into BC cells and specifically targets the ER by binding to the receptor with relatively high (60-100%) affinity.4,5 The labeling of fluoroestradiol with F 18 provides a positron-emitting form of this estrogen analog for visualization on PET imaging.4,5 PET scans with Cerianna measure regional estrogen binding activity in BC cells, enabling detection of lesions that overexpress the ER.5,14 Cerianna uptake measured by PET in BC tumors is directly proportional to tumor ER expression measured by in vitro assays.5

*CoA = coenzyme A, E = estradiol, ER = estrogen receptor, ERE = estrogen response element.
F18 fluoroestradiol is not useful for imaging other receptors, such as HER2 and the PR, or for assessing regions with high activity due to hepatobiliary and urinary excretion. 3,5

Verified concordance with biopsy for determining ER status in MBC* 1

Data from a meta-analysis assessed published results comparing F18 fluoroestradiol PET and tissue assays of ER status in patients with BC.1For the primary analysis, researchers analyzed 4 studies that provided F18 fluoroestradiol PET lesion-specific information for non-breast tumors in patients with MBC. The primary analysis included 113 non-breast lesions.

Sensitivity estimated by the hierarchical summary receiver-operating characteristic (HSROC) curve models was 0.78 (95% CR, 0.65-0.88) and specificity was 0.98 (95% CR, 0.65-1.00).1

*The F18 fluoroestradiol administered in this study was not equivalent to the FDA-approved formulation of Cerianna. Data from a meta-analysis that aimed to assess lesion-level agreement between ER expression by IHC assay and qualitative assessment by F18 fluoroestradiol PET. The primary analysis focused on non-breast tumors in patients with metastatic disease. HSROC curve models were used to summarize test accuracy while accounting for variability due to threshold across studies and treating IHC results as the reference standard. Sensitivity estimated by the HSROC curve models was 0.78 (95% CR, 0.65-0.88) and specificity was 0.98 (95% CR, 0.65-1.00).1

Distinct mode of action that may help inform clinical decisions

F18 fluoroestradiol and FDG PET images in a MBC treatment responder and non-responder*†15

Patient 1 (anterior/superior) responded to treatment with an AI and a CDK 4/6 inhibitor*15
Patient 2 (anterior/superior) did not respond to treatment with an AI and a CDK 4/6 inhibitor*15

*AI = aromatase inhibitor, CDK = cyclin-dependent kinase, FDG = 18F-fluorodeoxyglucose, Tx = treatment.
Upper row responder: Baseline FDG PET (A) showed pathological uptake in axillary lymph nodes (right side) and in nearly all vertebrae and pelvic bones. Image B showed the baseline F18 fluoroestradiol PET with pathological ER expression in the axial skeleton (including vertebrae, pelvic bones, proximal humeri and femora) and in axillary lymph nodes (right side). After 8 weeks, the FDG PET (C) showed almost complete metabolic response (just some slightly elevated uptake in the axillary lymph nodes). The patient had been on treatment for more than 70 weeks. Lower row non-responder: Baseline FDG PET (D) showed pathological uptake in multiple skeletal lesions. Image E showed the baseline F18 fluoroestradiol PET with only some increased ER expression in thoracic vertebrae. After 8 weeks, the FDG PET (F) showed no metabolic response, even some increase in the pathologic uptake in the multiple skeletal lesions.15

Images from a prospective, single center, feasibility study that aimed to explore whether baseline F18 fluoroestradiol PET discordance and F18 fluoroestradiol uptake were correlated with outcome and response to concomitant treatment with an AI and a CDK 4/6 inhibitor. Thirty patients with ER+ MBC were included in the study, including 87% who received at least one previous line of ET in the metastatic setting.15

Have a question? We would love to hear from you.

Important Safety Information


CERIANNA is indicated for use with positron emission tomography (PET) imaging for the detection of estrogen receptor (ER)-positive lesions as an adjunct to biopsy in patients with recurrent or metastatic breast cancer.


Limitations of Use:

Tissue biopsy should be used to confirm recurrence of breast cancer and to verify ER status by pathology. CERIANNA is not useful for imaging other receptors, such as human epidermal growth factor receptor 2 (HER2) and the progesterone receptor (PR).


Important Safety Information



•  None.




Risk of Misdiagnosis

Inadequate Tumor Characterization and Other ER-Positive Pathology

•   Breast cancer may be heterogeneous within patients and across time. CERIANNA images ER and is not useful for imaging other receptors such as HER2 and PR. The uptake of fluoroestradiol F 18 is not specific for breast cancer and may occur in a variety of ER-positive tumors that arise outside of the breast, including from the uterus and ovaries. Do not use CERIANNA in lieu of biopsy when biopsy is indicated in patients with recurrent or metastatic breast cancer.


False Negative CERIANNA Scan

•   A negative CERIANNA scan does not rule out ER-positive breast cancer. Pathology or clinical characteristics that suggest a patient may benefit from systemic hormone therapy should take precedence over a discordant negative CERIANNA scan.


Radiation Risks

•   Diagnostic radiopharmaceuticals, including CERIANNA, expose patients to radiation. Radiation exposure is associated with a dose-dependent increased risk of cancer. Ensure safe drug handling and patient preparation procedures (including adequate hydration and voiding) to protect patients and

health care providers from unintentional radiation exposure.


Pregnancy Status

•   Assessment of pregnancy status is recommended in females of reproductive potential before administering CERIANNA.




•   In Clinical Trials (n=1207) the most common adverse reactions seen occurred at a rate < 1% were injection-site pain and dysgeusia.





Risk Summary

•   All radiopharmaceuticals, including CERIANNA, have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of radiation dose. Advise a pregnant woman of the potential risks of fetal exposure to radiation from administration of CERIANNA.


•   There are no available data on CERIANNA use in pregnant women. No animal reproduction studies using fluoroestradiol F 18 have been conducted to evaluate its effect on female reproduction and embryo-fetal development.


•   The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.



Risk Summary

•   There are no data on the presence of fluoroestradiol F 18 in human milk, or its effects on the breastfed infant or milk production. Lactation studies have not been conducted in animals. Advise a lactating woman to avoid breastfeeding for 4 hours after CERIANNA administration in order to minimize radiation exposure to a breastfed infant.


Pediatric Use

•  The safety and effectiveness of CERIANNA in pediatric patients have not been established.


Geriatric Use

  • Clinical studies of fluoroestradiol F 18 injection did not reveal any difference in pharmacokinetics or biodistribution in patients aged 65 and over.




   Systemic Endocrine Therapies that Bind to ER


  • Drugs that bind to the ER, including SERMs and SERDs, may compete with the binding of fluoroestradiol F18 and may reduce detection of ER-positive lesions with CERIANNA.


  • Before administration of CERIANNA, discontinue drugs that bind to the ER, such as SERMs and SERDs, for at least 5 biological half-lives: ( e.g. elacestrant for 11 days, tamoxifen for 8 weeks and fulvestrant for 28 weeks).
