Malvern, Pa., and New York, N.Y.|05/28/2020

• New radiopharmaceutical intended for PET imaging of metastatic breast cancer patients
• Commercial availability slated for late 2020/early 2021
• PETNET Solutions, Inc., is exclusive U.S. commercial supplier

PETNET Solutions, Inc., a Siemens Healthineers company, and Zionexa USA, a wholly owned subsidiary of Zionexa SAS, have announced that the Food and Drug Administration (FDA) has approved Cerianna™ (fluoroestradiol F 18) injection for intravenous use. Cerianna (fluoroestradiol F 18) is a molecular imaging agent indicated for use in positron emission tomography (PET) imaging for the detection of estrogen receptor-positive lesions as an adjunct to biopsy in patients with recurrent or metastatic breast cancer. Cerianna (fluoroestradiol F 18) is the first FDA-approved F-18 PET imaging agent specifically indicated for use in patients with recurrent or metastatic breast cancer.

Cerianna (fluoroestradiol F 18) will be commercially available beginning in late 2020/early 2021 through PETNET Solutions, Inc., Zionexa USA’s manufacturer and exclusive commercial distributor in the U.S. Additional manufacturing sites will be added as each site receives regulatory approval to commence manufacturing.

“PETNET Solutions, Inc., is proud to work with Zionexa USA as the exclusive U.S. commercial supplier making Cerianna (fluoroestradiol F 18) accessible to imaging centers and their breast cancer patients,” said Barry Scott, Head of PETNET Solutions, Inc. “Our extensive network of radiopharmacies enables us to increase access to cutting-edge radiotracers such as Cerianna (fluoroestradiol F 18), helping healthcare facilities address the challenge of recurrent and metastatic breast cancer.”

“Zionexa is pleased to be able to make Cerianna (fluoroestradiol F 18) commercially available through the extensive manufacturing network of PETNET Solutions, Inc.,” said Peter Webner, Chief Executive Officer of Zionexa USA. “PETNET has been a great partner to Zionexa and has surpassed our expectations as a contract manufacturer. Cerianna (fluoroestradiol F 18) will provide clinicians with additional, previously unavailable data on the estrogen receptor status of tumors across the patient’s entire body, providing additional data to enhance therapeutic decision-making.”

CERIANNA is a radioactive diagnostic agent 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.


· Recommended dose is 222 MBq (6 mCi), with a range of 111 MBq to 222 MBq (3 mCi to 6 mCi), administered as an intravenous injection over 1 to 2 minutes.
· Recommended imaging start time is 80 minutes (range 20 minutes to 80 minutes) after drug administration.
· See full prescribing information for additional preparation, administration, imaging, and radiation dosimetry information.

Injection: 148 MBq/mL to 3,700 MBq/mL (4 mCi/mL to 100 mCi/mL) of fluoroestradiol F 18 in a multiple-dose vial.

Reported adverse reactions include: injection-site pain and dysgeusia

· Risk of Misdiagnosis. Do not use CERIANNA in lieu of biopsy when biopsy is indicated in patients with recurrent or metastatic 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. Ensure safe drug handling and patient preparation procedures to protect patients and health care providers from unintentional radiation exposure.

· Drugs such as tamoxifen and fulvestrant that block the estrogen receptor reduce the uptake of fluoroestradiol F 18. Do not delay indicated therapy in order to administer CERIANNA. Image patients with CERIANNA prior to starting systemic endocrine therapies that block ER.

· Lactation: Interrupt breastfeeding. Advise a lactating woman to avoid breastfeeding for 4 hours after CERIANNA administration

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).
