Closely monitor the infusion site for extravasation or drug infiltration during administration. Limiting the infusion of paclitaxel protein-bound particles for injectable suspension (albumin-bound) to 30 minutes may reduce the risk of infusion-related reactions [see Adverse Reactions (6.2) ] .

5 WARNINGS AND PRECAUTIONS • Sensory neuropathy occurs frequently and may require dose reduction or treatment interruption. ( 5.2 ) • Sepsis occurred in patients with or without neutropenia who received paclitaxel protein-bound particles for injectable suspension (albumin-bound) in combination with gemcitabine; interrupt paclitaxel protein-bound particles for injectable suspension (albumin-bound) and gemcitabine until sepsis resolves, and if neutropenia, until neutrophils are at least 1500 cells/mm 3 , then resume treatment at reduced dose levels. ( 5.3 ) • Pneumonitis occurred with the use of paclitaxel protein-bound particles for injectable suspension (albumin-bound) in combination with gemcitabine; permanently discontinue treatment with paclitaxel protein-bound particles for injectable suspension (albumin-bound) and gemcitabine. ( 5.4 ) • Severe hypersensitivity reactions with fatal outcome have been reported. Do not rechallenge with this drug. ( 4 , 5.5 ) • Exposure and toxicity of paclitaxel can be increased in patients with hepatic impairment, consider dose reduction and closely monitor patients with hepatic impairment. ( 2.5 , 5.6 ) • Paclitaxel protein-bound particles for injectable suspension (albumin-bound) contains albumin derived from human blood, which has a theoretical risk of viral transmission. ( 5.7 ) • Paclitaxel protein-bound particles for injectable suspension (albumin-bound) can cause fetal harm. Advise patients of potential risk to a fetus and to use effective contraception. ( 5.8 , 8.1 , 8.3 ) 5.1 Severe Myelosuppression Severe myelosuppression (primarily neutropenia) is dose-dependent and a dose-limiting toxicity of paclitaxel protein-bound particles for injectable suspension (albumin-bound). In clinical studies, Grade 3 to 4 neutropenia occurred in 34% of patients with metastatic breast cancer (MBC), 47% of patients with non-small cell lung cancer (NSCLC), and 38% of patients with pancreatic cancer. Monitor for severe neutropenia and thrombocytopenia by performing complete blood cell counts frequently, including prior to dosing on Day 1 (for MBC) and Days 1, 8, and 15 (for NSCLC and for pancreatic cancer). Do not administer paclitaxel protein-bound particles for injectable suspension (albumin-bound) to patients with baseline absolute neutrophil counts (ANC) of less than 1,500 cells/mm 3 [see Contraindications (4) ] . In the case of severe neutropenia (<500 cells/mm 3 for seven days or more) during a course of paclitaxel protein-bound particles for injectable suspension (albumin-bound) therapy, reduce the dose of paclitaxel protein-bound particles for injectable suspension (albumin-bound) in subsequent courses in patients with MBC or NSCLC. In patients with MBC, resume treatment with every-3-week cycles of paclitaxel protein-bound particles for injectable suspension (albumin-bound) after ANC recovers to a level >1,500 cells/mm 3 and platelets recover to a level >100,000 cells/mm 3 . In patients with NSCLC, resume treatment if recommended at permanently reduced doses for both weekly paclitaxel protein-bound particles for injectable suspension (albumin-bound) and every-3-week carboplatin after ANC recovers to at least 1500 cells/mm 3 and platelet count of at least 100,000 cells/mm 3 on Day 1 or to an ANC of at least 500 cells/mm 3 and platelet count of at least 50,000 cells/mm 3 on Days 8 or 15 of the cycle [see Dosage and Administration (2.6) ]. In patients with adenocarcinoma of the pancreas, withhold paclitaxel protein-bound particles for injectable suspension (albumin-bound) and gemcitabine if the ANC is less than 500 cells/mm 3 or platelets are less than 50,000 cells/mm 3 and delay initiation of the next cycle if the ANC is less than 1500 cells/mm 3 or platelet count is less than 100,000 cells/mm 3 on Day 1 of the cycle. Resume treatment with appropriate dose reduction if recommended [see Dosage and Administration (2.6) ]. 5.2 Severe Neuropathy Sensory neuropathy is dose- and schedule-dependent [see …

4 CONTRAINDICATIONS Paclitaxel protein-bound particles for injectable suspension (albumin-bound) is contraindicated in patients with: • Baseline neutrophil counts of < 1,500 cells/mm 3 [see Warnings and Precautions (5.1) ] • A history of severe hypersensitivity reactions to paclitaxel protein-bound particles for injectable suspension (albumin-bound) [see Warnings and Precautions (5.5) ] • Neutrophil counts of < 1,500 cells/mm 3 . ( 4 ) • Severe hypersensitivity reactions to paclitaxel protein-bound particles for injectable suspension (albumin-bound). ( 4 )

7 DRUG INTERACTIONS The metabolism of paclitaxel is catalyzed by CYP2C8 and CYP3A4. Caution should be exercised when administering paclitaxel protein-bound particles for injectable suspension (albumin-bound) concomitantly with medicines known to inhibit or induce either CYP2C8 or CYP3A4. Use caution when concomitantly administering paclitaxel protein-bound particles for injectable suspension (albumin-bound) with inhibitors or inducers of either CYP2C8 or CYP3A4. ( 7 )

8.1 Pregnancy Risk Summary Based on its mechanism of action and findings in animals, paclitaxel protein-bound particles for injectable suspension (albumin-bound) can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available human data on paclitaxel protein-bound particles for injectable suspension (albumin-bound) use in pregnant women to inform the drug-associated risk. In animal reproduction studies, administration of paclitaxel formulated as albumin-bound particles to pregnant rats during the period of organogenesis resulted in embryo-fetal toxicity at doses approximately 2% of the daily maximum recommended human dose on a mg/m 2 basis (see Data ). Advise females of reproductive potential of the potential risk to a fetus. The background rate of major birth defects and miscarriage is unknown for the indicated population. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In embryo-fetal development studies, intravenous administration of paclitaxel formulated as albumin-bound particles to rats during pregnancy, on gestation days 7 to 17 at doses of 6 mg/m 2 (approximately 2% of the daily maximum recommended human dose on a mg/m 2 basis) caused embryo-fetal toxicities, as indicated by intrauterine mortality, increased resorptions (up to 5-fold), reduced numbers of litters and live fetuses, reduction in fetal body weight, and increase in fetal anomalies. Fetal anomalies included soft tissue and skeletal malformations, such as eye bulge, folded retina, microphthalmia, and dilation of brain ventricles.
