    2.6 Dosage Modifications for Adverse Reactions

    Metastatic Breast Cancer
    Patients who experience severe neutropenia (neutrophils less than 500 cells/mm 3for a week or longer) or severe sensory neuropathy during paclitaxel protein-bound particles for injectable suspension (albumin-bound) therapy should have dosage reduced to 220 mg/m 2for subsequent courses of paclitaxel protein-bound particles for injectable suspension (albumin-bound). For recurrence of severe neutropenia or severe sensory neuropathy, additional dose reduction should be made to 180 mg/m 2. For Grade 3 sensory neuropathy hold treatment until resolution to Grade 1 or 2, followed by a dose reduction for all subsequent courses of paclitaxel protein-bound particles for injectable suspension (albumin-bound)  [see Contraindications (4), Warnings and Precautions (5.1, 5.2)and Adverse Reactions (6.1)].

    2.7 Preparation for Intravenous Administration

    Paclitaxel protein-bound particles for injectable suspension (albumin-bound) is a cytotoxic drug. Follow applicable special handling and disposal procedures. 1The use of gloves is recommended. If paclitaxel protein-bound particles for injectable suspension (albumin-bound) (lyophilized cake or reconstituted suspension) contacts the skin, wash the skin immediately and thoroughly with soap and water. Following topical exposure to paclitaxel, events may include tingling, burning, and redness. If paclitaxel protein-bound particles for injectable suspension (albumin-bound) contacts mucous membranes, the membranes should be flushed thoroughly with water.

    Paclitaxel protein-bound particles for injectable suspension (albumin-bound) is supplied as a sterile lyophilized powder for reconstitution before use.

    Read the entire preparation instructions prior to reconstitution.

    1. Aseptically, reconstitute each vial by injecting 20 mL of 0.9% Sodium Chloride Injection, USP.
    2. Slowly inject the 20 mL of 0.9% Sodium Chloride Injection, USP, over a minimum of 1 minute, using the
      sterile syringe to direct the solution flow onto the INSIDE WALL OF THE VIAL.
      reconstitution
    3. DO NOT INJECT the 0.9% Sodium Chloride Injection, USP, directly onto the lyophilized cake as this
      will result in foaming.
    4. Once the injection is complete, allow the vial to sit for a minimum of 5 minutes to ensure proper wetting of
      the lyophilized cake/powder.
    5. Gently swirl and/or invert the vial slowly for at least 2 minutes until complete dissolution of any cake/powder
      occurs. Avoid generation of foam.
    6. If foaming or clumping occurs, stand solution for at least 15 minutes until foam subsides.

    Each mL of the reconstituted formulation will contain 5 mg/mL paclitaxel.

    The reconstituted suspension should be milky and homogenous without visible particulates. If particulates or settling are visible, the vial should be gentlyinverted again to ensure complete resuspension prior to use. Discard the reconstituted suspension if precipitates are observed. Discard any unused portion.

    Calculate the exact total dosing volume of 5 mg/mL suspension required for the patient and slowly withdraw the dosing volume of the reconstituted suspension from the vial(s) into a syringe: Dosing volume (mL)=Total dose (mg)/5 (mg/mL).

    Inject the appropriate amount of reconstituted paclitaxel protein-bound particles for injectable suspension (albumin-bound) into an empty, sterile intravenous bag [plasticized polyvinyl chloride (PVC) containers, PVC or non-PVC type intravenous bag]. The use of specialized DEHP-free solution containers or administration sets is not necessary to prepare or administer paclitaxel protein-bound particles for injectable suspension (albumin-bound) infusions. The use of medical devices containing silicone oil as a lubricant (i.e., syringes and intravenous bags) to reconstitute and administer paclitaxel protein-bound particles for injectable suspension (albumin-bound) may result in the formation of proteinaceous strands.

    Visually inspect the reconstituted paclitaxel protein-bound particles for injectable suspension (albumin-bound) suspension in the intravenous bag prior to administration. Discard the reconstituted suspension if proteinaceous strands, particulate matter, or discoloration are observed.

    2.8 Stability

    Unopened vials of paclitaxel protein-bound particles for injectable suspension (albumin-bound) are stable until the date indicated on the package when stored between 20°C to 25°C (68°F to 77°F) in the original package. Neither freezing nor refrigeration adversely affects the stability of the product.

    Stability of Reconstituted Suspension in the Vial
    Reconstituted paclitaxel protein-bound particles for injectable suspension (albumin-bound) in the vial should be used immediately, but may be refrigerated at 2°C to 8°C (36°F to 46°F) for a maximum of 24 hours if necessary. If not used immediately, each vial of reconstituted suspension should be replaced in the original carton to protect it from bright light. Discard any unused portion.

    Stability of Reconstituted Suspension in the Infusion Bag
    The suspension for infusion when prepared as recommended in an infusion bag should be used immediately, but may be refrigerated at 2°C to 8°C (36°F to 46°F) and protected from bright light for a maximum of 24 hours.

    The total combined refrigerated storage time of reconstituted paclitaxel protein-bound particles for injectable suspension (albumin-bound) in the vial and in the infusion bag is 24 hours. This may be followed by storage in the infusion bag at ambient temperature (approximately 25°C) and lighting conditions for a maximum of 4 hours.

    Discard any unused portion.

  • 3 DOSAGE FORMS AND STRENGTHS

    For injectable suspension, for intravenous use: white to yellow, sterile lyophilized powder containing 100 mg of paclitaxel formulated as albumin-bound particles in single-dose vial for reconstitution.

  • 4 CONTRAINDICATIONS

    Paclitaxel protein-bound particles for injectable suspension (albumin-bound) is contraindicated in patients with:

  • 5 WARNINGS AND PRECAUTIONS

    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).

    Monitor for severe neutropenia and thrombocytopenia by performing complete blood cell counts frequently, including prior to dosing on Day 1 (for MBC). 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 3for 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.

    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 3and platelets recover to a level >100,000 cells/mm 3[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 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 ≥ 1,500, 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. 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 pregnant woman. In animal reproduction studies, administration of paclitaxel formulated as albumin-bound particles to rats during pregnancy at doses lower than the maximum recommended human dose, based on body surface area, caused embryo-fetal toxicities, including intrauterine mortality, increased resorptions, reduced numbers of live fetuses, and malformations.

    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)  [see Use in Specific Populations (8.1, 8.3), Clinical Pharmacology (12.1)].

    Based on findings from genetic toxicity and animal reproduction studies, 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)  [see Use in Specific Populations (8.1, 8.3), Nonclinical Toxicology (13.1)].

    Other Adverse Reactions

    Hematologic Disorders
    Neutropenia was dose dependent and reversible. Among patients with metastatic breast cancer in the randomized trial, neutrophil counts declined below 500 cells/mm 3(Grade 4) in 9% of the patients treated with a dose of 260 mg/m 2compared to 22% in patients receiving paclitaxel injection at a dose of 175 mg/m 2. Pancytopenia has been observed in clinical trials.

    Infections
    Infectious episodes were reported in 24% of the patients treated with paclitaxel protein-bound particles for injectable suspension (albumin-bound). Oral candidiasis, respiratory tract infections and pneumonia were the most frequently reported infectious complications.

    Hypersensitivity Reactions (HSRs)
    Grade 1 or 2 HSRs occurred on the day of paclitaxel protein-bound particles for injectable suspension (albumin-bound) administration and consisted of dyspnea (1%) and flushing, hypotension, chest pain, and arrhythmia (all <1%). The use of paclitaxel protein-bound particles for injectable suspension (albumin-bound) in patients previously exhibiting hypersensitivity to paclitaxel injection or human albumin has not been studied.

    Cardiovascular
    Hypotension, during the 30-minute infusion, occurred in 5% of patients. Bradycardia, during the 30-minute infusion, occurred in <1% of patients. These vital sign changes most often caused no symptoms and required neither specific therapy nor treatment discontinuation.

    Severe cardiovascular events possibly related to single-agent paclitaxel protein-bound particles for injectable suspension (albumin-bound) occurred in approximately 3% of patients. These events included cardiac ischemia/infarction, chest pain, cardiac arrest, supraventricular tachycardia, edema, thrombosis, pulmonary thromboembolism, pulmonary emboli, and hypertension. Cases of cerebrovascular attacks (strokes) and transient ischemic attacks have been reported.

    Electrocardiogram (ECG) abnormalities were common among patients at baseline. ECG abnormalities on study did not usually result in symptoms, were not dose-limiting, and required no intervention. ECG abnormalities were noted in 60% of patients. Among patients with a normal ECG prior to study entry, 35% of all patients developed an abnormal tracing while on study. The most frequently reported ECG modifications were non-specific repolarization abnormalities, sinus bradycardia, and sinus tachycardia.

    Respiratory
    Dyspnea (12%), cough (7%), and pneumothorax (<1%) were reported after treatment with paclitaxel protein-bound particles for injectable suspension (albumin-bound).

    Neurologic
    The frequency and severity of sensory neuropathy increased with cumulative dose. Sensory neuropathy was the cause of paclitaxel protein-bound particles for injectable suspension (albumin-bound) discontinuation in 7/229 (3%) patients. Twenty-four patients (10%) treated with paclitaxel protein-bound particles for injectable suspension (albumin-bound) developed Grade 3 peripheral neuropathy; of these patients, 14 had documented improvement after a median of 22 days; 10 patients resumed treatment at a reduced dose of paclitaxel protein-bound particles for injectable suspension (albumin-bound) and 2 discontinued due to peripheral neuropathy. Of the 10 patients without documented improvement, 4 discontinued the study due to peripheral neuropathy.

    No Grade 4 sensory neuropathies were reported. Only one incident of motor neuropathy (Grade 2) was observed in either arm of the controlled trial.

    Vision Disorders
    Ocular/visual disturbances occurred in 13% of all patients (n=366) treated with paclitaxel protein-bound particles for injectable suspension (albumin-bound) and 1% were severe. The severe cases (keratitis and blurred vision) were reported in patients who received higher doses than those recommended (300 or 375 mg/m 2). These effects generally have been reversible.

    Arthralgia/Myalgia
    The symptoms were usually transient, occurred two or three days after paclitaxel protein-bound particles for injectable suspension (albumin-bound) administration, and resolved within a few days.

    Hepatic
    Grade 3 or 4 elevations in GGT were reported for 14% of patients treated with paclitaxel protein-bound particles for injectable suspension (albumin-bound) and 10% of patients treated with paclitaxel injection in the randomized trial.

    Renal
    Overall 11% of patients experienced creatinine elevation, 1% severe. No discontinuations, dose reductions, or dose delays were caused by renal toxicities.

    Other Clinical Events
    Nail changes (changes in pigmentation or discoloration of nail bed) have been reported. Edema occurred in 10% of patients; no patients had severe edema. Dehydration and pyrexia were also reported.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during postapproval use of paclitaxel protein-bound particles for injectable suspension (albumin-bound) or with paclitaxel injection and may be expected to occur with paclitaxel protein-bound particles for injectable suspension (albumin-bound). 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 paclitaxel protein-bound particles for injectable suspension (albumin-bound) and other taxanes has been reported.

    Cardiovascular

    Congestive heart failure, left ventricular dysfunction, and atrioventricular block. Most patients were previously exposed to cardiotoxic drugs, such as anthracyclines, or had underlying cardiac history.

    Respiratory

    Pneumonitis, interstitial pneumonia, and pulmonary embolism

    Radiation pneumonitis in patients receiving concurrent radiotherapy.

    Lung fibrosis has been reported with paclitaxel injection.

    Neurologic

    Cranial nerve palsies and vocal cord paresis, as well as autonomic neuropathy resulting in paralytic ileus.

    Vision Disorders

    Reduced visual acuity due to cystoid macular edema (CME). After cessation of treatment, CME may improve, and visual acuity may return to baseline. Abnormal visual evoked potentials in patients treated with paclitaxel injection suggest persistent optic nerve damage.

    Hepatic

    Hepatic necrosis and hepatic encephalopathy leading to death in patients treated with paclitaxel injection.

    Gastrointestinal (GI)

    Intestinal obstruction, intestinal perforation, pancreatitis, and ischemic colitis. In patients treated with paclitaxel injection, neutropenic enterocolitis (typhlitis) despite the coadministration of G-CSF, alone and in combination with other chemotherapeutic agents.

    Injection Site Reaction

    Extravasation. Closely monitor the paclitaxel protein-bound particles for injectable suspension (albumin-bound) infusion site for possible infiltration during drug administration [see Dosage and Administration 2.1)] .

    Severe events such as phlebitis, cellulitis, induration, necrosis, and fibrosis have been reported with paclitaxel injection. In some cases, the onset of the injection site reaction occurred during a prolonged infusion or was delayed up to ten days. Recurrence of skin reactions at a site of previous extravasation following administration of paclitaxel injection at a different site has been reported.

    Metabolic and Nutritional Disorders

    Tumor lysis syndrome

    Other Clinical Events

    Skin reactions including generalized or maculopapular rash, erythema, and pruritus

    Photosensitivity reactions, radiation recall phenomenon, scleroderma, and in some patients previously exposed to capecitabine, reports of palmar-plantar erythrodysesthesia. Stevens-Johnson syndrome and toxic epidermal necrolysis have been reported.

    Conjunctivitis, cellulitis, and increased lacrimation have been reported with paclitaxel injection.

    Accidental Exposure

    Upon inhalation of paclitaxel, dyspnea, chest pain, burning eyes, sore throat, and nausea have been reported.

    Following topical exposure, tingling, burning, and redness have been reported.

  • 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.

  • 8 USE IN SPECIFIC POPULATIONS

    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 2basis (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 2basis) 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.

    8.2 Lactation

    Risk Summary

    There are no data on the presence of paclitaxel in human milk, or its effect on the breastfed child or on milk production. In animal studies, paclitaxel and/or its metabolites were excreted into the milk of lactating rats (see Data). Because of the potential for serious adverse reactions in a breastfed child from paclitaxel protein-bound particles for injectable suspension (albumin-bound), advise lactating women not to breastfeed during treatment with paclitaxel protein-bound particles for injectable suspension (albumin-bound) and for two weeks after the last dose.

    Data

    Animal Data

    Following intravenous administration of radiolabeled paclitaxel to rats on days 9 to 10 postpartum, concentrations of radioactivity in milk were higher than in plasma and declined in parallel with the plasma concentrations.

    8.3 Females and Males of Reproductive Potential

    Based on animal studies and mechanism of action, paclitaxel protein-bound particles for injectable suspension (albumin-bound) can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].

    Verify the pregnancy status of females of reproductive potential prior to starting treatment with paclitaxel protein-bound particles for injectable suspension (albumin-bound).

    Contraception

    Females

    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).

    Males

    Based on findings in genetic toxicity and animal reproduction studies, advise males 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)  [see Use in Specific Populations (8.1)and Nonclinical Toxicology (13.1)].

    Infertility

    Females and Males

    Based on findings in animals, paclitaxel protein-bound particles for injectable suspension (albumin-bound) may impair fertility in females and males of reproductive potential [see Nonclinical Toxicology (13.1)] .

    8.4 Pediatric Use

    Safety and effectiveness in pediatric patients have not been established. Pharmacokinetics, safety, and antitumor activity of paclitaxel protein-bound particles for injectable suspension (albumin-bound) were assessed in an open-label, dose escalation, dose expansion study ( NCT01962103) in 96 pediatric patients aged 1.4 to < 17 years with recurrent or refractory pediatric solid tumors. The maximum tolerated dose (MTD) normalized for body surface area (BSA) was lower in pediatric patients compared to adults. No new safety signals were observed in pediatric patients across these studies.

    Paclitaxel protein-bound exposures normalized by dose were higher in 96 pediatric patients (aged 1.4 to < 17 years) as compared to those in adults.

    8.5 Geriatric Use

    Of the 229 patients in the randomized study who received paclitaxel protein-bound particles for injectable suspension (albumin-bound) for the treatment of metastatic breast cancer, 13% were at least 65 years of age and < 2% were 75 years or older. This study of paclitaxel protein-bound particles for injectable suspension (albumin-bound) did not include a sufficient number of patients with metastatic breast cancer who were 65 years and older to determine whether they respond differently from younger patients.

    A subsequent pooled analysis was conducted in 981 patients receiving paclitaxel protein-bound particles for injectable suspension (albumin-bound) monotherapy for metastatic breast cancer, of which 15% were 65 years of age or older and 2% were 75 years of age or older. A higher incidence of epistaxis, diarrhea, dehydration, fatigue, and peripheral edema was found in patients 65 years of age or older.

    8.6 Renal Impairment

    No adjustment of the starting paclitaxel protein-bound particles for injectable suspension (albumin-bound) dose is required for patients with mild to moderate renal impairment (estimated creatinine clearance 30 to <90 mL/min) [see Clinical Pharmacology (12.3)]. There are insufficient data to permit dosage recommendations in patients with severe renal impairment or end stage renal disease (estimated creatinine clearance <30 mL/min).

    8.7 Hepatic Impairment

    No adjustment of the starting paclitaxel protein-bound particles for injectable suspension (albumin-bound) dose is required for patients with mild hepatic impairment (total bilirubin > ULN and ≤ 1.5 x ULN and aspartate aminotransferase [AST] ≤ 10 x ULN). Reduce paclitaxel protein-bound particles for injectable suspension (albumin-bound) starting dose in patients with moderate to severe hepatic impairment [see Dosage and Administration (2.5)and Clinical Pharmacology (12.3)] . Paclitaxel protein-bound particles for injectable suspension (albumin-bound) is not recommended for use in patients with total bilirubin > 5 x ULN or AST > 10 x ULN [see Dosage and Administration (2.5), Warnings and Precautions (5.6), and Clinical Pharmacology (12.3)] . 

  • 10 OVERDOSAGE

    There is no known antidote for paclitaxel protein-bound particles for injectable suspension (albumin-bound) overdosage. The primary anticipated complications of overdosage would consist of bone marrow suppression, sensory neurotoxicity, and mucositis.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Paclitaxel protein-bound particles for injectable suspension (albumin-bound) is a microtubule inhibitor that promotes the assembly of microtubules from tubulin dimers and stabilizes microtubules by preventing depolymerization. This stability results in the inhibition of the normal dynamic reorganization of the microtubule network that is essential for vital interphase and mitotic cellular functions. Paclitaxel induces abnormal arrays or "bundles" of microtubules throughout the cell cycle and multiple asters of microtubules during mitosis.

    12.3 Pharmacokinetics

    The pharmacokinetics of total paclitaxel following 30- and 180-minute infusions of paclitaxel protein-bound particles for injectable suspension (albumin-bound) at dose levels of 80 to 375 mg/m 2(0.31 to 1.15 times the maximum approved recommended dosage) were determined in clinical studies. Dose levels of mg/m 2refer to mg of paclitaxel in paclitaxel protein-bound particles for injectable suspension (albumin-bound). Following intravenous administration of paclitaxel protein-bound particles for injectable suspension (albumin-bound) to patients with solid tumors, paclitaxel plasma concentrations declined in a biphasic manner, the initial rapid decline representing distribution to the peripheral compartment and the slower second phase representing drug elimination.

    Following paclitaxel protein-bound particles for injectable suspension (albumin-bound) infusion, paclitaxel exhibited linear drug exposure (AUC) across clinical doses ranging from 80 to 300 mg/m 2(0.31 to 1.15 times the maximum approved recommended dosage). The pharmacokinetics of paclitaxel in paclitaxel protein-bound particles for injectable suspension (albumin-bound) were independent of the duration of intravenous administration.

    The pharmacokinetic data of 260 mg/m 2 paclitaxel protein-bound particles for injectable suspension (albumin-bound) administered over a 30-minute infusion was compared to the pharmacokinetics of 175 mg/m 2paclitaxel injection over a 3-hour infusion. Clearance was larger (43%) and the volume of distribution was higher (53%) for paclitaxel protein-bound particles for injectable suspension (albumin-bound) than for paclitaxel injection. There were no differences in terminal half-lives.

    Distribution

    Following paclitaxel protein-bound particles for injectable suspension (albumin-bound) administration to patients with solid tumors, paclitaxel is evenly distributed into blood cells and plasma and is highly bound to plasma proteins (94%). The total volume of distribution is approximately 1741 L; the large volume of distribution indicates extensive extravascular distribution and/or tissue binding of paclitaxel.

    In a within-patient comparison study, the fraction of unbound paclitaxel in plasma was significantly higher with paclitaxel protein-bound particles for injectable suspension (albumin-bound) (6.2%) than with solvent-based paclitaxel (2.3%). This contributes to significantly higher exposure to unbound paclitaxel with paclitaxel protein-bound particles for injectable suspension (albumin-bound) compared with solvent-based paclitaxel, when the total exposure is comparable. In vitrostudies of binding to human serum proteins, using paclitaxel concentrations ranging from 0.1 to 50 µg/mL, indicated that the presence of cimetidine, ranitidine, dexamethasone, or diphenhydramine did not affect protein binding of paclitaxel.

    Elimination
    At the clinical dose range of 80 to 300 mg/m 2(0.31 to 1.15 times the maximum approved recommended dosage), the mean total clearance of paclitaxel ranges from 13 to 30 L/h/m 2and the mean terminal half-life ranges from 13 to 27 hours.

    Metabolism
    In vitrostudies with human liver microsomes and tissue slices showed that paclitaxel in paclitaxel protein-bound particles for injectable suspension (albumin-bound) was metabolized primarily to 6α-hydroxypaclitaxel by CYP2C8; and to two minor metabolites, 3'- p-hydroxypaclitaxel and 6α, 3'- p-dihydroxypaclitaxel, by CYP3A4. In vitro, the metabolism of paclitaxel to 6α-hydroxypaclitaxel was inhibited by a number of agents (ketoconazole, verapamil, diazepam, quinidine, dexamethasone, cyclosporin, teniposide, etoposide, and vincristine), but the concentrations used exceeded those found in vivofollowing normal therapeutic doses. Testosterone, 17α-ethinyl estradiol, retinoic acid, and quercetin, a specific inhibitor of CYP2C8, also inhibited the formation of 6α-hydroxypaclitaxel in vitro. The pharmacokinetics of paclitaxel may also be altered in vivoas a result of interactions with compounds that are substrates, inducers, or inhibitors of CYP2C8 and/or CYP3A4 [see Drug Interactions (7)] .

    Excretion
    After a 30-minute infusion of 260 mg/m 2doses of paclitaxel protein-bound particles for injectable suspension (albumin-bound), the mean values for cumulative urinary recovery of unchanged drug (4%) indicated extensive non-renal clearance. Less than 1% of the total administered dose was excreted in urine as the metabolites 6α-hydroxypaclitaxel and 3'- p-hydroxypaclitaxel. Fecal excretion was approximately 20% of the total dose administered.

    Specific Populations

    No clinically meaningful differences in the pharmacokinetics of paclitaxel in paclitaxel protein-bound particles for injectable suspension (albumin-bound) were observed based on body weight (40 to 143 kg), body surface area (1.3 to 2.4 m 2), sex, race (Asian vs. White), age (24 to 85 years), type of solid tumors, mild to moderate renal impairment (creatinine clearance 30 to <90 mL/min), and mild hepatic impairment (total bilirubin >1 to ≤1.5 x ULN and AST ≤10 x ULN).

    Patients with moderate (total bilirubin >1.5 to 3 x ULN and AST ≤10 x ULN) or severe (total bilirubin >3 to 5 x ULN) hepatic impairment had a 22% to 26% decrease in the maximum elimination rate of paclitaxel and approximately 20% increase in mean paclitaxel AUC compared with patients with normal hepatic function (total bilirubin ≤ULN and AST ≤ULN) [see Dosage and Administration (2.5)and Use in Specific Populations (8.7)] .

    The effect of severe renal impairment or end stage renal disease (creatinine clearance < 30 mL/min) on the pharmacokinetics of paclitaxel in paclitaxel protein-bound particles for injectable suspension (albumin-bound) is unknown.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    The carcinogenic potential of paclitaxel protein-bound particles for injectable suspension (albumin-bound) has not been studied.

    Paclitaxel was clastogenic in vitro(chromosome aberrations in human lymphocytes) and in vivo(micronucleus test in mice). Paclitaxel was not mutagenic in the Ames test or the CHO/HGPRT gene mutation assay.

    Administration of paclitaxel formulated as albumin-bound particles to male rats at 42 mg/m 2on a weekly basis (approximately 16% of the daily maximum recommended human exposure on a body surface area basis) for 11 weeks prior to mating with untreated female rats resulted in significantly reduced fertility accompanied by decreased pregnancy rates and increased loss of embryos in mated females. A dose of 42 mg/m 2also reduced male reproductive organ weights, mating performance, and sperm production. Testicular atrophy/degeneration was observed in single-dose toxicology studies in animals administered paclitaxel formulated as albumin-bound particles at doses lower than the recommended human dose; doses were 54 mg/m 2in rodents and 175 mg/m 2in dogs. Similar testicular degeneration was seen in monkeys administered three weekly doses of 108 mg/m 2paclitaxel formulated as albumin bound particles.

    Administration of paclitaxel prior to and during mating produced impairment of fertility in male and female rats. Paclitaxel caused reduced fertility and reproductive indices, and increased embryo-fetal toxicity.

  • 14 CLINICAL STUDIES

    14.1 Metastatic Breast Cancer

    Data from 106 patients accrued in two single arm open label studies and from 460 patients enrolled in a randomized comparative study were available to support the use of paclitaxel protein-bound particles for injectable suspension (albumin-bound) in metastatic breast cancer.

    Single Arm Open Label Studies
    In one study, paclitaxel protein-bound particles for injectable suspension (albumin-bound) was administered as a 30-minute infusion at a dose of 175 mg/m 2to 43 patients with metastatic breast cancer. The second trial utilized a dose of 300 mg/m 2as a 30-minute infusion in 63 patients with metastatic breast cancer. Cycles were administered at 3-week intervals. Objective responses were observed in both studies.

    Randomized Comparative Study
    This multicenter trial was conducted in 460 patients with metastatic breast cancer. Patients were randomized to receive paclitaxel protein-bound particles for injectable suspension (albumin-bound) at a dose of 260 mg/m 2given as a 30-minute infusion, or paclitaxel injection at 175 mg/m 2given as a 3-hour infusion. Sixty-four percent of patients had impaired performance status (ECOG 1 or 2) at study entry; 79% had visceral metastases; and 76% had > 3 sites of metastases. Fourteen percent of the patients had not received prior chemotherapy; 27% had received chemotherapy in the adjuvant setting, 40% in the metastatic setting and 19% in both metastatic and adjuvant settings. Fifty-nine percent received study drug as second or greater than second-line therapy. Seventy-seven percent of the patients had been previously exposed to anthracyclines.

    In this trial, patients in the paclitaxel protein-bound particles for injectable suspension (albumin-bound) treatment arm had a statistically significantly higher reconciled target lesion response rate (the trial primary endpoint) of 21.5% (95% CI: 16.2% to 26.7%), compared to 11.1% (95% CI: 6.9% to 15.1%) for patients in the paclitaxel injection treatment arm. See Table 11. There was no statistically significant difference in overall survival between the two study arms.
