A post‐hoc analysis of POSLUMA clinical trials demonstrated that urinary activity did not impact image assessment for 96% of patients (682/712) by majority read1.” POSLUMA represents a newer class of high‐affinity PSMA‐targeted PET radiopharmaceuticals based on novel radiohybrid technology and leverages the high image quality of 18F‐labeled PSMA PET imaging to help facilitate detection of prostate cancer. It can provide clinically valuable information to guide patient management based on its high‐affinity PSMA binding, low urinary uptake and positive performance at very low PSA levels. POSLUMA is included in nationally recognized clinical oncology guidelines for prostate cancer, covered by the vast majority of insurance plans and is readily available for patients across the country through the network of Blue Earth Diagnostics’ commercial U.S. manufacturer and distributor, PETNET Solutions Inc, A Siemens Healthineers Company. Indication and Important Safety Information About POSLUMA INDICATION POSLUMA® (flotufolastat F 18) injection is indicated for positron emission tomography (PET) of prostate‐ specific membrane antigen (PSMA) positive lesions in men with prostate cancer • with suspected metastasis who are candidates for initial definitive therapy • with suspected recurrence based on elevated serum prostate‐specific antigen (PSA) level IMPORTANT SAFETY INFORMATION Image interpretation errors can occur with POSLUMA PET. A negative image does not rule out the presence of prostate cancer and a positive image does not confirm the presence of prostate cancer. The performance of POSLUMA for imaging metastatic pelvic lymph nodes in patients prior to initial definitive therapy seems to be affected by serum PSA levels and risk grouping. The performance of POSLUMA for imaging patients with biochemical evidence of recurrence of prostate cancer seems to be affected by serum PSA levels. Flotufolastat F 18 uptake is not specific for prostate cancer and may occur in other types of cancer, in non‐malignant processes, and in normal tissues. Clinical correlation, which may include histopathological evaluation, is recommended. Risk of Image Misinterpretation in Patients with Suspected Prostate Cancer Recurrence: The interpretation of POSLUMA PET may differ depending on imaging readers, particularly in the prostate/prostate bed region. Because of the associated risk of false positive interpretation, consider multidisciplinary consultation and histopathological confirmation when clinical decision‐making hinges on flotufolastat F 18 uptake only in the prostate/prostate bed region or only on uptake interpreted as borderline. POSLUMA use contributes to a patient’s overall long‐term cumulative radiation exposure. Long‐ term cumulative radiation exposure is associated with an increased risk for cancer. Advise patients to hydrate before and after administration and to void frequently after administration. Ensure safe handling to minimize radiation exposure to the patient and health care providers. The adverse reactions reported in ≥0.4% of patients in clinical studies were diarrhea, blood pressure increase and injection site pain. Drug Interactions: androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, may result in changes in uptake of flotufolastat F 18 in prostate cancer. The effect of these therapies on performance of POSLUMA PET has not been established. To report suspected adverse reactions to POSLUMA, call 1‐844‐POSLUMA (1‐844‐767‐5862) or contact FDA at 1‐800‐FDA‐1088 or www.fda.gov/medwatch.
