Notably, Emory University’s independent EMPIRE‐1 study (NCT01666808), published in The Lancet, demonstrated that treatment informed by Axumin PET imaging significantly improved event‐free‐survival for men with recurrent prostate cancer at three and four years. Those results included 30 (38%) patients with recurrent prostate cancer who were on ADT in the Axumin arm.” Dr. Gauden continued, “Axumin PET imaging has informed healthcare decisions for more than 165,000 men with recurrent prostate cancer across the United States, where it is available at more than 1,350 imaging centers and widely reimbursed. Blue Earth Diagnostics is committed to helping patients through innovative diagnostic solutions that empower the evolution of care for men with recurrent prostate cancer, and we look forward to helping even more patients in the future.” Highlights of the publications “Effect of Hormonal Therapy on 18F‐Fluciclovine PET/CT in the Detection of Prostate Cancer Recurrence, Localization of Metastatic Disease and Correlation with Prostate‐specific Antigen” (DOI: https://doi.org/10.1016/j.urolonc.2022.05.018) The study was designed to explore the impact of androgen deprivation therapy (ADT) on the performance of 18F‐fluciclovine. A retrospective analysis was conducted to compare the 18F‐fluciclovine PET/CT positivity rate in 320 patients with biochemical recurrence of prostate cancer receiving ADT at the time of the scan with the rate achieved in those not receiving ADT. For each group, the number of positive 18F‐fluciclovine PET/CT scans (positivity rate) was evaluated for the whole body, prostate/bed, and extraprostatic regions. and rates were correlated with PSA. The 18F‐fluciclovine positivity rate was analyzed at the patient level, in the prostate/bed region and at each extraprostatic site (pelvic lymph nodes, extrapelvic lymph nodes, bone and soft tissue or other metastatic sites). Positivity rates were stratified according to whether or not the patient was receiving ADT at the time of scan. At the time of the 18F‐fluciclovine scan, 68/320 (21%) patients were on ADT, while 252/320 (79%) were not. The median Gleason score was 8 (range of 6–10) in the ADT group vs. 7 (range of 6–10) in the non‐ ADT group. Overall, positivity rates demonstrated no statistical significance between the ADT and non‐ ADT groups. Positivity rates (ADT vs. non‐ADT) were 82% (56/68) vs. 82% (206/252) for the whole body, 57% (39/68) vs. 60% (152/252) for prostate/bed, and 60% (41/68) vs. 53% (133/252) for extraprostatic regions. No significant difference was observed between ADT and non‐ADT groups at different PSA levels. The authors cited certain limitations to the study, among them its retrospective nature and lack of histopathological data, and unknown duration of ADT therapy. As stated in the abstract, the authors concluded that “detection of prostate cancer recurrence with 18F‐fluciclovine PET/CT is not significantly influenced by ADT, suggesting that localization of disease in patients with detectable PSA who are receiving ADT is feasible with 18F‐fluciclovine.”1 The manuscript, “Effect of Hormonal Therapy on 18F‐Fluciclovine PET/CT in the Detection of Prostate Cancer Recurrence, Localization of Metastatic Disease and Correlation with Prostate‐specific Antigen” was published online on June 21, 2022, in Urologic Oncology.

The study was designed to investigate the impact of concurrent ADT on disease detection with 18F‐ fluciclovine PET in patients with metastatic prostate cancer following primary therapy. Data from 71 patients who had been receiving ADT for at least 3 months at the time of undergoing an 18F‐fluciclovine PET/CT scan were retrospectively reviewed. The reasons for the PET/CT scan were rising PSA (n=58), staging of advanced disease (n=4) or therapeutic monitoring (n=9). Malignant lesions with increased uptake of 18F‐fluciclovine were detected in 60/73 (82%) of the scans; 33 (45%) had lesions in the prostate/bed and 46 (63%) in extraprostatic sites. Patients received ADT for a median of 2 years pre‐scan. The time on ADT did not influence detection. The detection rates were 89% for patients who had received ADT for < 1year, 63% for a period of 1 ‐ <2 years, 83% for 2 ‐ 4 years, 78% for > 4 ‐ 10 years and 67% for a treatment period of >10 years. The authors cited certain limitations to the study, including its retrospective nature and lack of histopathological data, and the inability to compare 18F‐fluciclovine scans while patients were on ADT and after withdrawal. As stated in the abstract, the authors concluded that “18F‐fluciclovine detected recurrent or metastatic lesions in 82% of patients with prostate cancer receiving ADT. The rates achieved are consistent with widely reported data for 18F‐fluciclovine PET/CT, suggesting that withdrawal of ADT before scanning is not necessary.”2 The manuscript, “Effect of Androgen Deprivation Therapy on the Results of PET/CT with 18F‐Fluciclovine in Patients with Metastatic Prostate Cancer” was published in Tomography on June 3, 2022.

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. 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. 4 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.
