11 DESCRIPTION PLUVICTO (lutetium Lu 177 vipivotide tetraxetan) is a radioligand therapeutic agent. Lutetium Lu 177 vipivotide tetraxetan is a PSMA-binding ligand bound to a DOTA chelator radiolabeled with lutetium-177. The chemical name is 2-[4-[2-[[4-[[(2S)-1-[[(5S)-5-carboxy-5-[[(1S)-1,3-dicarboxy propyl]carbamoylamino]pentyl]amino]-3-naphthalen-2-yl-1-oxopropan-2-yl]carbamoyl]cyclohexyl]methylamino]-2-oxoethyl]-4,7,10-tris(carboxylatomethyl)-1,4,7,10-tetrazacyclododec-1-yl]acetate; lutetium-177(3+). The molecular mass is 1216.06 g/mol and the molecular formula is C 49 H 68 177 LuN 9 O 16 . The chemical structure for lutetium Lu 177 vipivotide tetraxetan is shown below: PLUVICTO (lutetium Lu 177 vipivotide tetraxetan) 1,000 MBq/mL (27 mCi/mL) Injection is supplied as a sterile, clear, colorless to slightly yellow solution for intravenous use. Each single-dose vial contains acetic acid (0.30 mg/mL), sodium acetate (0.41 mg/mL), gentisic acid (0.39 mg/mL), sodium ascorbate (50.0 mg/mL), pentetic acid (0.10 mg/mL), and water for injection (q.s. to 1 mL).

Dosage and Administration
2 DOSAGE AND ADMINISTRATION Select patients for treatment using LOCAMETZ ® or another approved PSMA positron emission tomography (PET) product based on PSMA expression in tumors. ( 2.2 ) Recommended Dosage: Administer 7.4 GBq (200 mCi) every 6 weeks for 6 doses. ( 2.3 ) Dose interruption, reduction, or permanent discontinuation may be required due to adverse reactions. ( 2.4 ) 2.1 Important Safety Instructions PLUVICTO is a radiopharmaceutical; handle with appropriate safety measures to minimize radiation exposure [see Warnings and Precautions (5.1)] . Use waterproof gloves and effective radiation shielding when handling PLUVICTO. Radiopharmaceuticals, including PLUVICTO, should be used by or under the control of healthcare providers who are qualified by specific training and experience in the safe use and handling of radiopharmaceuticals, and whose experience and training have been approved by the appropriate governmental agency authorized to license the use of radiopharmaceuticals. 2.2 Patient Selection Select patients with previously treated mCRPC for treatment with PLUVICTO using LOCAMETZ or another approved PSMA positron emission tomography (PET) product based on PSMA expression in tumors. Additional selection criteria were used in clinical studies [see Clinical Studies (14)] . 2.3 Recommended Dosage The recommended PLUVICTO dosage is 7.4 GBq (200 mCi) intravenously every 6 weeks for 6 doses, or until disease progression, or unacceptable toxicity. 2.4 Dosage Modifications for Adverse Reactions Recommended dosage modifications of PLUVICTO for adverse reactions are provided in Table 1. Management of adverse reactions may require temporary dose interruption, dose reduction or permanent discontinuation of treatment with PLUVICTO. If a treatment delay due to an adverse reaction persists for > 4 weeks, consider permanent discontinuation of PLUVICTO. The dose of PLUVICTO may be reduced by 20% to 5.9 GBq (160 mCi) once; do not re-escalate dose. If a patient has further adverse reactions that would require an additional dose reduction, treatment with PLUVICTO must be discontinued.

Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Myelosuppression [see Warnings and Precautions (5.2)] Renal Toxicity [see Warnings and Precautions (5.3)] Most common (≥ 20%) adverse reactions, including laboratory abnormalities, were decreased lymphocytes, decreased hemoglobin, fatigue, dry mouth, decreased platelets, decreased estimated glomerular filtration rate, nausea, decreased neutrophils, decreased calcium, decreased sodium, increased aspartate aminotransferase, increased alkaline phosphatase, arthralgia, decreased appetite, increased potassium, constipation, and back pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Novartis Pharmaceuticals Corporation at 1-888-669-6682 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. In the pooled safety population for the PSMAfore and VISION studies (N = 756), the most common (≥ 20%) adverse reactions, including laboratory abnormalities, were decreased lymphocytes (83%), decreased hemoglobin (65%), fatigue (49%), dry mouth (46%), decreased platelets (40%), decreased estimated glomerular filtration rate (37%), nausea (35%), decreased neutrophils (31%), decreased calcium (29%), decreased sodium (27%), increased aspartate aminotransferase (26%), increased alkaline phosphatase (24%), arthralgia (22%), decreased appetite (21%), increased potassium (21%), constipation (21%), and back pain (21%). PSMAfore The safety of PLUVICTO was evaluated in the PSMAfore study in patients with progressive, PSMA-positive mCRPC previously treated with ARPI therapy, for whom it was considered appropriate to delay taxane-based chemotherapy by the investigator [see Clinical Studies (14.1)] . Patients received at least one dose of either PLUVICTO 7.4 GBq (200 mCi) administered every 6 weeks (N = 227) or a change in ARPI (N = 232). The median duration of exposure to PLUVICTO was 8.4 months (range, 0.4 to 11.6), and the median number of doses of PLUVICTO received was 6 (range, 1 to 6). The median cumulative administered activity of PLUVICTO was 42.4 GBq (range, 7.0 to 45.4). Serious adverse reactions occurred in 20% of patients who received PLUVICTO. Serious adverse reactions in > 1% of patients who received PLUVICTO included anemia (1.8%), urinary tract infection (1.8%), hemorrhage (1.3%), and sepsis (1.3%). Fatal adverse reactions occurred in 1.8% of patients who received PLUVICTO, including COVID-19 pneumonia, cardiac arrest, intestinal ischemia, and sepsis (0.4% each). PLUVICTO was permanently discontinued due to adverse reactions in 6% of patients. Adverse reactions leading to permanent discontinuation of PLUVICTO in ≥ 1% of patients who received PLUVICTO were thrombocytopenia (1.8%) and dry mouth (1.3%). Adverse reactions leading to a dose interruption of PLUVICTO occurred in 12% of patients. The most frequent (≥ 1%) adverse reactions leading to a dose interruption of PLUVICTO in patients who received PLUVICTO were COVID-19 (3.1%) and anemia (1.8%). Adverse reactions leading to a dose reduction of PLUVICTO occurred in 3.5% of patients. The most frequent (≥ 0.5%) adverse reaction leading to a dose reduction of PLUVICTO in patients who received PLUVICTO was dry mouth (0.9%). Table 3 and Table 4 summarize the incidence of adverse reactions and laboratory abnormalities, respectively, in PSMAfore.

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary The safety and efficacy of PLUVICTO have not been established in females. Based on its mechanism of action, PLUVICTO can cause fetal harm [see Clinical Pharmacology (12.1)] . There are no available data on PLUVICTO use in pregnant females. No animal studies using lutetium Lu 177 vipivotide tetraxetan have been conducted to evaluate its effect on female reproduction and embryo-fetal development; however, all radioactive emissions, including those from PLUVICTO, can cause fetal harm.
Overdosage
10 OVERDOSAGE In the event of administration of a radiation overdosage with PLUVICTO, reduce the radiation absorbed dose to the patient by increasing the elimination of the radionuclide from the body by frequent micturition or by forced diuresis and frequent bladder voiding. Estimate the effective radiation dose that was applied and treat with additional supportive care measures as clinically indicated.
