Warnings & Precautions
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 3-4 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/mm3 [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 either 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 Adverse Reactions (6.1) ] . If ≥ Grade 3 sensory neuropathy develops, withhold Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) treatment until resolution to Grade 1 or 2 for metastatic breast cancer or until resolution to ≤ Grade 1 for NSCLC and pancreatic cancer followed by a dose reduction for all subsequent courses of Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) [see Dosage and Administration (2.6) ] . 5.3 Sepsis Sepsis occurred in 5% of patients with or without neutropenia who received Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) in combination with gemcitabine. Biliary obstruction or presence of biliary stent were risk factors for severe or fatal sepsis. If a patient becomes febrile (regardless of ANC) initiate treatment with broad spectrum antibiotics. For febrile neutropenia, interrupt Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) and gemcitabine until fever resolves and ANC ≥ 1500, then resume treatment at reduced dose levels [see Dosage and Administration (2.6) ] . 5.4 Pneumonitis Pneumonitis, including some cases that were fatal, occurred in 4% of patients receiving Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) in combination with gemcitabine. Monitor patients for signs and symptoms of pneumonitis and interrupt Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) and gemcitabine during evaluation of suspected pneumonitis. After ruling out infectious etiology and upon making a diagnosis of pneumonitis, permanently discontinue treatment with Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) and gemcitabine. 5.5 Severe Hypersensitivity Severe and sometimes fatal hypersensitivity reactions, including anaphylactic reactions, have been reported. Do not rechallenge patients who experience a severe hypersensitivity reaction to Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) with this drug [see Contraindications (4) ] . Cross-hypersensitivity between Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) and other taxane products has been reported and may include severe reactions such as anaphylaxis. Closely monitor patients with a previous history of hypersensitivity to other taxanes during initiation of Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) therapy. 5.6 Use in Patients with Hepatic Impairment The exposure and toxicity of paclitaxel can be increased in patients with hepatic impairment. Closely monitor patients with hepatic impairment for severe myelosuppression. Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) is not recommended in patients who have total bilirubin >5 x ULN or AST >10 x ULN. In addition, Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) is not recommended in patients with metastatic adenocarcinoma of the pancreas who have moderate to severe hepatic impairment (total bilirubin >1.5 x ULN and AST ≤10 x ULN). Reduce the starting dose for patients with moderate or severe hepatic impairment [see Dosage and Administration (2.5) , Use in Specific Populations (8.7) , Clinical Pharmacology (12.3) ] . 5.7 Albumin (Human) Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) contains albumin (human), a derivative of human blood. Based on effective donor screening and product manufacturing processes, it carries a remote risk for transmission of viral diseases. A theoretical risk for transmission of Creutzfeldt-Jakob Disease (CJD) also is considered extremely remote. No cases of transmission of viral diseases or CJD have ever been identified for albumin. 5.8 Embryo-Fetal Toxicity Based on mechanism of action and findings in animals, Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) can cause fetal harm when administered to a

Use in Pregnancy & Lactation
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.
