5 WARNINGS AND PRECAUTIONS Risk for Misinterpretation: Gallium Ga 68 gozetotide uptake can be seen in a variety of tumor types and in non-malignant processes. Interpretation of ILLUCCIX PET imaging with histopathology and/or other diagnostic procedures is recommended. ( 5.1 ) Radiation Risks: Ensure safe handling to protect patients and health care providers from unintentional radiation exposure. ( 2.1 , 5.2 ) 5.1 Risk for Misinterpretation Image interpretation errors can occur with ILLUCCIX 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. Gallium Ga 68 gozetotide uptake is not specific for prostate cancer and may occur with other types of cancer as well as non-malignant processes such as Paget's disease, fibrous dysplasia, and osteophytosis. Clinical correlation, which may include histopathological evaluation of the suspected prostate cancer site, is recommended. The performance of ILLUCCIX for imaging of biochemically recurrent prostate cancer seems to be affected by serum PSA levels and by site of disease. The performance of ILLUCCIX for imaging of metastatic pelvic lymph nodes prior to initial definitive therapy seems to be affected by Gleason score [ see Clinical Studies (14.1 , 14.2) ] . 5.2 Radiation Risks Gallium Ga 68 gozetotide contributes to a patient's overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk for cancer. Ensure safe handling to minimize radiation exposure to the patient and health care providers. Advise patients to hydrate before and after administration and to void frequently after administration [see Dosage and Administration ( 2.1 , 2.3 )] .

6 ADVERSE REACTIONS The most commonly reported adverse reactions (incidence ≥ 0.5%) include fatigue, nausea, constipation, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Telix Pharmaceuticals (US) Inc. at 1-844-455-8638 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of ILLUCCIX has been established based on three prospective studies of gallium Ga 68 gozetotide in patients with prostate cancer (i.e., Studies 1, 2, and 3). Adverse reactions from these studies are reported below. In Studies 1 and 2 using another formulation of gallium Ga 68 gozetotide injection, 960 patients received one dose of gallium Ga 68 gozetotide intravenously with the amount (mean ± SD) of radioactivity 188.7 ± 40.7 MBq (5.1 ± 1.1 mCi) [ see Clinical Studies ( 14.1 , 14.2 ) ]. The most commonly reported adverse reactions were nausea, diarrhea, and dizziness, occurring at a rate of <1%. In a randomized, multicenter, open-label clinical study (NCT03511664, referred to as Study 3) in which gallium Ga 68 gozetotide was used to identify PSMA-positive patients on PET imaging to determine eligibility for PSMA-directed therapy, 1,003 patients with progressive metastatic castration-resistant prostate cancer (mCRPC) received one dose of gallium Ga 68 gozetotide intravenously with the amount of radioactivity 167.1 ± 23.1 MBq (4.52 ± 0.62 mCi). Patients were males with median age of 70 years (range, 40 to 94 years), were White (87%), Black or African American (7%), or Asian (2.4%), and had median baseline PSA levels of 74 ng/mL (range, 0 to 8,995 ng/mL). Adverse reactions occurring at ≥ 0.5% in patients with metastatic prostate cancer who received gallium Ga 68 gozetotide injection in Study 3 are presented in Table 4. Table 4 : Adverse Reactions (≥ 0.5%) in Patients with Metastatic Prostate Cancer Who Received Gallium Ga 68 Gozetotide Injection in Study 3 Adverse Reaction Gallium Ga 68 Gozetotide Injection N = 1,003 n (%) General disorders Fatigue 12 (1.2) Gastrointestinal disorders Nausea 8 (0.8) Constipation 5 (0.5) Vomiting 5 (0.5) Adverse reactions occurring at a rate of < 0.5% in the study were diarrhea, dry mouth, injection site reactions, including injection site hematoma and injection site warmth and chills. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of ILLUCCIX. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. General Disorders and Administration Site Conditions : injection site pain.
