IMPORTANT SAFETY INFORMATION INCLUDING BOXED WARNING

CONTRAINDICATIONS

• Baseline neutrophil counts of <1500 cells/mm³.
• A history of severe hypersensitivity reactions to Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound).

WARNINGS AND PRECAUTIONS

Severe Myelosuppression

• Severe myelosuppression (primarily neutropenia) is dose-dependent and a dose-limiting toxicity of protein-bound paclitaxel. 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.
• In the case of severe neutropenia (<500 cells/mm³ for 7 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 after ANC recovers to a level >1500 cells/mm³ and platelets recover to a level >100,000 cells/mm³. 
• In patients with NSCLC, resume treatment if recommended at permanently reduced doses for both weekly Paclitaxel Protein-Bound Particles and every-3-week carboplatin after ANC recovers to at least 1500 cells/mm³ and platelet count of at least 100,000 cells/mm³ on Day 1 or to an ANC of at least 500 cells/mm³ and platelet count of at least 50,000 cells/mm³ on Days 8 or 15 of the cycle.
• In patients with adenocarcinoma of the pancreas, withhold Paclitaxel Protein-Bound Particles and gemcitabine if the ANC is less than 500 cells/mm³ or platelets are less than 50,000 cells/mm³ and delay initiation of the next cycle if the ANC is less than 1500 cells/mm³ or platelet count is less than 100,000 cells/mm³ on Day 1 of the cycle. Resume treatment with appropriate dose reduction if recommended.

Severe Neuropathy

• Sensory neuropathy is dose- and schedule-dependent, occurs frequently and may require dose reduction or treatment interruption.
• 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 MBC or until resolution to ≤ Grade 1 for NSCLC and pancreatic cancer followed by a dose reduction for all subsequent courses.

Sepsis

• Sepsis occurred in 5% of patients with or without neutropenia who received protein-bound paclitaxel 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 sepsis resolves, and if neutropenia, until neutrophils are at least 1500 cells/mm³, then resume treatment at reduced dose levels.

Pneumonitis

• Pneumonitis, including some cases that were fatal, occurred in 4% of patients with or without neutropenia with the use of protein-bound paclitaxel in combination with gemcitabine.
• Monitor patients for signs and symptoms and interrupt Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) and gemcitabine during evaluation of suspected pneumonitis. 
• Permanently discontinue treatment with Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) and gemcitabine upon making a diagnosis of pneumonitis.

Severe Hypersensitivity

• Severe and sometimes fatal hypersensitivity reactions, including anaphylactic reactions. Cross-hypersensitivity between protein-bound paclitaxel 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 therapy.
• Do not rechallenge patients who experience a severe hypersensitivity reaction to Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) with this drug.

Use in Patients with Hepatic Impairment

• 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 a total bilirubin >5 x ULN or AST >10 x ULN.
• For MBC and NSCLC, the starting dose should be reduced for patients with moderate or severe hepatic impairment.
• For pancreatic adenocarcinoma, Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) is not recommended for patients with moderate to severe hepatic impairment (total bilirubin >1.5 x ULN and AST ≤10 x ULN).

Albumin (Human)

• Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) contains albumin derived from human blood, which has a remote risk of viral transmission.

Embryo-Fetal Toxicity

• Can cause fetal harm when administered to a pregnant woman. (See Special Populations).
• Advise females of reproductive potential of the potential risk to a fetus.
•  Advise females of reproductive potential to use effective contraception and avoid becoming pregnant during treatment with Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) and for at least six months after the last dose of Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound).
• Advise male patients with female partners of reproductive potential to use effective contraception and avoid fathering a child during treatment with Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) and for at least three months after the last dose of Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound).

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of protein-bound paclitaxel or with paclitaxel injection and may be expected to occur with protein-bound paclitaxel. 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.

• Hypersensitivity Reactions: Severe and sometimes fatal hypersensitivity reactions. Cross-hypersensitivity between protein bound and other taxanes has been reported.
• Cardiovascular: Congestive heart failure, left ventricular dysfunction, and atrioventricular block.
• Respiratory: Pneumonitis, interstitial pneumonia, pulmonary embolism, radiation pneumonitis, lung fibrosis.
• Neurologic: Cranial nerve palsies, vocal cord paresis, autonomic neuropathy resulting in paralytic ileus.
• Vision Disorders: Reduced visual acuity due to cystoid macular edema. Abnormal visual evoked potentials suggest persistent optic nerve damage.
• Hepatic: Hepatic necrosis and hepatic encephalopathy leading to death.
• Gastrointestinal: Intestinal obstruction, intestinal perforation, pancreatitis, ischemic colitis, neutropenic enterocolitis.
• Injection Site Reaction: Extravasation. Severe events such as phlebitis, cellulitis, induration, necrosis, and fibrosis. Recurrence of skin reactions at a site of previous extravasation following administration of paclitaxel injection at a different site.
