Results from on‐site reads were compared to morphological imaging and validated by histopathology. Patient‐based analysis indicated that the sensitivity, specificity and diagnostic accuracy of rhPSMA‐7.3 (18F) PET imaging were 81.3% (95% CI, 54.4–96.0%), 87.5 (95% CI, 73.2–95.8%) and 85.7% (95% CI, 73.8–93.6%), respectively. Those for morphological imaging were 33.3% (95% CI, 13.3–59.0%), 89.5% (95% CI, 75.2–97.1%) and 71.4% (95% CI, 57.8–82.7%), respectively. On template‐based analysis, the sensitivity, specificity and accuracy of rhPSMA‐7.3 (18F) PET were 63.6% (95% CI, 45.4‐79.6%), 97.9% (95% CI, 95.5‐99.2%) and 94.4% (95% CI, 91.2‐96.6%), respectively, and those for morphological imaging were 15.2% (95% CI, 5.11‐31.9%), 99.3%(95% CI, 97.5‐99.9%) and 90.6% (95% CI, 86.9‐93.6%), respectively. The mean PSA level of the patients in this primary prostate cancer study was 11.0 ng/mL. About rhPSMA rhPSMA‐7.3 (18F) consists of a radiohybrid Prostate‐Specific Membrane Antigen (PSMA)‐targeted receptor ligand which attaches to and is internalized by prostate cancer cells, and is labeled with the 18F radioisotope for PET imaging. rhPSMA compounds can also be labeled with radioisotopes such as 177Lu and 225Ac for therapeutic use. Blue Earth Diagnostics acquired exclusive, worldwide rights to rhPSMA imaging technology from Scintomics in 2018, with an option to therapeutic rights. rhPSMA originated from the Technical University of Munich, Germany, and has been utilized clinically under German legislation at the Department of Nuclear Medicine there for the diagnostic imaging of men with both primary and recurrent prostate cancer. rhPSMA compounds have not received regulatory approval. NOTE: Axumin® (fluciclovine F 18) injection is FDA‐approved for positron emission tomography (PET) imaging in men with suspected prostate cancer recurrence based on elevated blood prostate specific antigen (PSA) levels following prior treatment. This press release is intended to provide information about Blue Earth Diagnostics’ business in the United States and Europe. Please be aware that the approval status and product label for Axumin varies by country worldwide. For EU Axumin product information refer to: http://www.ema.europa.eu/ema/index.jsp?curl=pages/medicines/human/medicines/004197/human_ med_002100.jsp&mid=WC0b01ac058001d124. U.S. Indication and Important Safety Information About Axumin INDICATION Axumin® (fluciclovine F 18) injection is indicated for positron emission tomography (PET) imaging in men with suspected prostate cancer recurrence based on elevated blood prostate specific antigen (PSA) levels following prior treatment. Document Number: PP--US-0037 IMPORTANT SAFETY INFORMATION Image interpretation errors can occur with Axumin PET imaging. A negative image does not rule out recurrent prostate cancer and a positive image does not confirm its presence. The performance of Axumin seems to be affected by PSA levels. Axumin uptake may occur with other cancers and benign prostatic hypertrophy in primary prostate cancer. Clinical correlation, which may include histopathological evaluation, is recommended. Hypersensitivity reactions, including anaphylaxis, may occur in patients who receive Axumin. Emergency resuscitation equipment and personnel should be immediately available. Axumin use contributes to a patient’s overall long‐term cumulative radiation exposure, which is associated with an increased risk of cancer. Safe handling practices should be used to minimize radiation exposure to the patient and health care providers. Adverse reactions were reported in ≤ 1% of subjects during clinical studies with Axumin. The most common adverse reactions were injection site pain, injection site erythema and dysgeusia. To report suspected adverse reactions to Axumin, call 1‐855‐AXUMIN1 (1‐855‐298‐6461) or contact FDA at 1‐800‐FDA‐1088 or www.fda.gov/medwatch. Full U.S. Axumin prescribing information is available at www.axumin.com. About Blue Earth Diagnostics Blue Earth Diagnostics is a leading molecular imaging diagnostics company focused on the development and commercialization of novel PET imaging agents to inform clinical management and guide care for cancer patients in areas of unmet medical need. Formed in 2014, Blue Earth Diagnostics is led by recognized experts in the clinical development and commercialization of innovative nuclear medicine products. The company’s first approved and commercially available product is Axumin® (fluciclovine F 18), a novel molecular imaging agent approved in the United States and European Union for use in PET imaging to detect and localize prostate cancer in men with a diagnosis of biochemical recurrence. Fluciclovine F 18 has a broad range of other potential applications in cancer imaging and Blue Earth Diagnostics is investigating the molecule for other cancers including in neuro‐oncology. The company's pipeline includes innovative Prostate Specific Membrane Antigen (PSMA)‐targeted radiohybrid ("rh") agents, which are a clinical‐stage, investigational class of theranostic compounds, with potential applications in both the imaging and treatment of prostate cancer. Blue Earth Diagnostics is a subsidiary of Bracco Imaging S.p.A., a global leader in diagnostic imaging. For more information, visit: www.blueearthdiagnostics.com.
