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.”
