Uses
1 INDICATIONS AND USAGE TRODELVY is a Trop-2-directed antibody and topoisomerase inhibitor conjugate indicated for the treatment of adult patients with: Locally Advanced or Metastatic Breast Cancer Unresectable locally advanced or metastatic triple-negative breast cancer (mTNBC) who have received two or more prior systemic therapies, at least one of them for metastatic disease. ( 1.1 , 14.1 ) Unresectable locally advanced or metastatic hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative (IHC 0, IHC 1+ or IHC 2+/ISH–) breast cancer who have received endocrine-based therapy and at least two additional systemic therapies in the metastatic setting.
Dosage
2 DOSAGE AND ADMINISTRATION Do NOT substitute TRODELVY for or use with other drugs containing irinotecan or its active metabolite SN-38. ( 2.1 ) For intravenous infusion only. Do not administer as an intravenous push or bolus. The recommended dose is 10 mg/kg once weekly on Days 1 and 8 of continuous 21-day treatment cycles until disease progression or unacceptable toxicity. ( 2.2 ) Premedication for prevention of infusion reactions and prevention of chemotherapy-induced nausea and vomiting is recommended. ( 2.2 ) Primary prophylaxis with G-CSF is recommended starting in the first cycle in all patients at increased risk of febrile neutropenia. ( 2.2 ) Monitor patients during the infusion and for at least 30 minutes after completion of infusion.

Interactions
7 DRUG INTERACTIONS UGT1A1 inhibitors or inducers: Avoid concomitant use. ( 7 ) 7.1 Effect of Other Drugs on TRODELVY UGT1A1 Inhibitors Concomitant administration of TRODELVY with inhibitors of UGT1A1 may increase the incidence of adverse reactions due to potential increase in systemic exposure to SN-38 [see Warning and Precaution (5.5) and Clinical Pharmacology (12.3 , 12.5) ] . Avoid administering UGT1A1 inhibitors with TRODELVY. UGT1A1 Inducers Exposure to SN-38 may be reduced in patients concomitantly receiving UGT1A1 enzyme inducers [see Warning and Precaution (5.5) and Clinical Pharmacology (12.3 , 12.5) ] . Avoid administering UGT1A1 inducers with TRODELVY.
Warnings
WARNING: NEUTROPENIA AND DIARRHEA TRODELVY can cause severe, life-threatening, or fatal neutropenia. Withhold TRODELVY for absolute neutrophil count below 1500/mm 3 or neutropenic fever. Monitor blood cell counts periodically during treatment. Primary prophylaxis with G-CSF is recommended for all patients at increased risk of febrile neutropenia [see Dosage and Administration (2.3) ] . 5 WARNINGS AND PRECAUTIONS Hypersensitivity and Infusion-Related Reactions: Hypersensitivity reactions including severe anaphylactic reactions have been observed. Monitor patients for infusion-related reactions. Permanently discontinue TRODELVY if severe or life-threatening reactions occur. ( 5.3 ) Nausea/Vomiting: Use antiemetic preventive treatment and withhold TRODELVY for patients with Grade 3 nausea or Grade 3–4 vomiting at the time of scheduled treatment. ( 5.4 ) Patients with Reduced UGT1A1 Activity: Individuals who are homozygous for the uridine diphosphate-glucuronosyl transferase 1A1 (UGT1A1)*28 allele are at increased risk for neutropenia, febrile neutropenia, and anemia following initiation of TRODELVY treatment. ( 5.5 ) Embryo-Fetal Toxicity: TRODELVY can cause fetal harm. 4 CONTRAINDICATIONS TRODELVY is contraindicated in patients who have experienced a severe hypersensitivity reaction to TRODELVY [see Warnings and Precautions (5.3) ] . Severe hypersensitivity reaction to TRODELVY. ( 4 , 5.3 )
Pregnancy
8.1 Pregnancy Risk Summary Based on its mechanism of action, TRODELVY can cause teratogenicity and/or embryo-fetal lethality when administered to a pregnant woman. There are no available data in pregnant women to inform the drug-associated risk. TRODELVY contains a genotoxic component, SN-38, and is toxic to rapidly dividing cells [see Clinical Pharmacology (12.1) and Nonclinical Toxicology (13.1) ] . Advise pregnant women and females of reproductive potential of the potential risk to a fetus.
Storage
Store vials in a refrigerator at 2°C to 8°C (36°F to 46°F) in the original carton to protect from light until time of reconstitution. Do not freeze. TRODELVY is a hazardous drug. Follow applicable special handling and disposal procedures 1 .
