NorthStar Medical Isotopes will supply Bayer with the medical radioisotope actinium-225 (Ac-225).

Under the terms of the deal, NorthStar will provide Bayer with non-carrier-added Ac-225 to be used by Bayer for several of its radiopharmaceutical programs. Ac-225 is a high-energy alpha-emitting radioisotope used in clinical trials to deliver therapeutic doses of radiation to destroy cancer cells in patients.

The radioisotope will be produced at a new dedicated Ac-225 production facility at NorthStar's Beloit, WI, campus, with the first shipments planned in 2024.

There are several conceivable advantages of F-18 FDG PET/CT over conventional imaging. Image A and B showing an example of the distinctive capability of the F-18 FDG PET/CT. A shows a fusion image of F-18 FDG PET/CT and low-dose CT and B an high resolution chest CT of a patient with an Aspergillus infection. The suspected aspergilloma is concealed on the high resolution CT due to the lung fluids and consolidation. Image C and D (fusion image of F-18 FDG PET/CT and low-dose CT and low-dose CT only, respectively) are examples of the ability to image inflammation while no concurrent abnormalities are visualized, in this case prostatitis (red arrows). Image E, a maximized intensity projection of F-18 FDG PET, shows a patient with lung infections and multiple muscle abscesses after MRSA sepsis. This is an illustrative example of a relevant dissemination investigation.

(A) Representative maximum-intensity projection and selected PET/CT images (fused, PET and CT only) of patient with metastatic prostate cancer at 1 hour after injection. (B and C) Low uptake of Ga-68 PSMA-R2 in salivary and submandibular glands is also demonstrated. (D) Images show heterogeneous uptake of Ga-68 PSMA-R2 with varying degrees of intensity in multiple spine bone lesions (vertebral sclerotic lesion with intense PSMA-R2 expression at its periphery indicated with red arrow).

Ga-68 FZ-NR-1 PET/CT images and F-18 FDG PET/CT and PET/MRI images in representative nectin-4-positive TNBC patients. (A) PET/CT images and nectin-4 immunohistochemistry (IHC) staining of patient 1. Maximum-intensity projection (MIP) images and axial and coronal PET/CT images of Ga-68 FZ-NR-1 and F-18 FDG both showed high uptake in lung metastases (arrow). (B) PET/CT images and nectin-4 IHC staining of patient 2. MIP images and axial and coronal PET/CT images of Ga-68 FZ-NR-1 showed high uptake in recurrence of right breast cancer after surgery (arrow), and those of F-18 FDG PET/MRI showed high uptake.
