NIOSH (Draft) 2020 List: Table 1
Observe and exercise appropriate precautions for handling, preparation, administration, and disposal of hazardous drugs.
Use double chemotherapy gloves and a protective gown. Prepare in a biological safety cabinet or compounding aseptic containment isolator with a closed system drug transfer device. Eye/face and respiratory protection may be needed during preparation and administration.
If nanoparticle albumin-bound (nab) paclitaxel comes in contact with the skin, wash the affected area immediately and thoroughly with soap and water. Following topical exposure, tingling, burning, and redness may occur. If contact occurs with mucous membranes, flush the affected area thoroughly with water.
Emetic Risk
Low
Administer routine antiemetic prophylaxis prior to treatment.
Extravasation Risk
Vesicant
Administer drug through central line.

Injectable Administration

Visually inspect parenteral product prior to administration; discard if proteinaceous strands, particulate matter, or discoloration are observed.

Intravenous Administration

Administer as an intravenous (IV) infusion over 30 minutes. Limiting the infusion time to 30 minutes reduces the likelihood of infusion-related reactions.
Each single-use 100-mg vial contains approximately 900 mg of human albumin.
Substitution for (or with) other paclitaxel formulations is prohibited. The albumin formulation of nab-paclitaxel significantly affects the volume of distribution, exposure, and clearance of unbound drugs relative to those of solvent-based paclitaxel.
Consider premedication for patients who have had prior hypersensitivity reactions to nab-paclitaxel.
 
Reconstitution
Slowly inject 20 mL of 0.9% Sodium Chloride Injection, USP onto the inside wall of the vial of lyophilized powder over a minimum of 1 minute.
Do not inject the 0.9% Sodium Chloride Injection, USP direction onto the lyophilized cake as this will cause foaming.
Allow the vial to sit for a minimum of 5 minutes to ensure proper wetting of the lyophilized cake/powder.
Gently swirl and/or invert the vial slowly for at least 2 minutes until complete dissolution occurs; avoid the generation of foam.
If foaming or clumping occurs, allow the solution to stand for at least 15 minutes until the foam subsides.
The reconstituted suspension should be milky and homogenous without visible particles. If particulates or settling are visible, gently invert the vial again to ensure complete resuspension prior to use. Each mL of the reconstituted suspension contains 5 mg/mL of paclitaxel.
Stability after reconstitution: Use immediately if possible. If not used immediately, each reconstituted vial should be replaced in the original carton to protect it from bright light; refrigerate between 2 to 8 degrees C (36 to 46 degrees F) for a maximum of 24 hours. The total combined refrigerated storage time of reconstituted nab-paclitaxel 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 degrees C) and lighting conditions for a maximum of 4 hours.
 
Dilution
Inject the appropriate amount of reconstituted nab-paclitaxel into an empty, sterile IV bag (plasticized PVC containers, PVC or non-PVC type IV bag).
It is not necessary to use specialized DEHP-free solution containers or administration sets for preparation or administration. However, the use of medical devices containing silicone oil as a lubricant (i.e., syringes and IV bags) may result in the formation of proteinaceous strands.
Stability after dilution: Use immediately if possible. If not used immediately, protect from bright light and refrigerate at 2 to 8 degrees C (36 to 46 degrees F) for a maximum of 24 hours. The total combined refrigerated storage time of reconstituted nab-paclitaxel 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 degrees C) and lighting conditions for a maximum of 4 hours.

Boxed Warning
Bone marrow suppression, neutropenia, thrombocytopenia

Bone marrow suppression (e.g., neutropenia, thrombocytopenia) is the dose-limiting toxicity of nanoparticle albumin-bound (nab) paclitaxel. Nab-paclitaxel is contraindicated in patients with a baseline absolute neutrophil count (ANC) of less than 1,500 cells/mm3. Obtain a complete blood count (CBC) panel prior to starting a new cycle of nab-paclitaxel therapy on day 1 in all patients and prior to therapy on day 8 and 15 in patients with non-small cell lung cancer and pancreatic cancer. Do not resume a new cycle of therapy until the ANC is 1,500 cells/mm3 or more and the platelet count is 100,000 cells/mm3 or more. In patients who develop severe neutropenia or thrombocytopenia, hold nab-paclitaxel and reduce the dose of therapy for subsequent cycles as recommended for the particular indication of use and chemotherapy regimen.

Description

Nanoparticle albumin-bound taxane; a microtubule inhibitor
Used for metastatic breast cancer, locally advanced or metastatic NSCLC, and metastatic pancreatic cancer
Do not start a new cycle if ANC is less than 1,500 cells/mm3; myelosuppression requires monitoring and possible adjustments in therapy

Dosage And Indications
For the treatment of breast cancer. For metastatic breast cancer after the failure of combination chemotherapy or relapse within 6 months of adjuvant chemotherapy.
NOTE: Prior therapy should have included an anthracycline unless clinically contraindicated. 
Intravenous dosage Adults

260 mg/m2 IV over 30 minutes every 3 weeks. The primary endpoint of overall response rate (ORR) was significantly improved with nab-paclitaxel compared with standard paclitaxel (33% vs. 19%; p = 0.001) administered every 3 weeks in patients with metastatic breast cancer in a multicenter, randomized, phase 3 trial (n = 460). Additionally, the median time to progression (TTP) was significantly longer with nab-paclitaxel compared with standard paclitaxel (23 weeks vs. 16.9 weeks). The TTP was significantly longer in patients treated with nab-paclitaxel as second line or greater (20.9 weeks vs. 16.1 weeks) but not as first line (24 weeks vs. 19.7 weeks) therapy. The median overall survival (OS) time was not significantly improved with nab-paclitaxel compared with standard paclitaxel (65 weeks vs. 55.7 weeks); however, the median OS time was significantly improved in the subpopulation of patients treated with nab-paclitaxel as second line or greater (56.4 weeks vs. 46.7 weeks).

For the treatment of taxane-refractory metastatic breast cancer†. Intravenous dosage Adults

100 mg/m2 IV over 30 minutes once per week for 3 weeks, then 1 week off, every 28 days. In a phase 2, open-label non-randomized study of taxane-refractory metastatic breast cancer patients, 14% achieved a response and 12% had stable disease.

For the treatment of previously untreated metastatic breast cancer†. Intravenous dosage Adults

100 mg/m2 to 150 mg/m2 IV over 30 minutes once per week for 3 weeks, then 1 week off, every 28 days. In a phase 2 trial, 302 patients with previously untreated metastatic breast cancer were randomized to receive nab-paclitaxel 100 mg/m2 or 150 mg/m2 weekly for 3 out of 4 weeks, nab-paclitaxel 300 mg/m2 once every 3 weeks, or docetaxel 100 mg/m2 once every 3 weeks. Overall response rate, the primary endpoint, was not significantly different between the groups. However, when reviewed by an independent radiologist, progression-free survival (PFS) was significantly improved in the nab-paclitaxel 150 mg/m2 arm vs. docetaxel (12.9 months vs. 7.5 months) and in the nab-paclitaxel 100 mg/m2 arm (12.8 months vs. 7.5 months); in the nab-paclitaxel 300 mg/m2 every 3 weeks arm PFS was 11 months.

For the first-line treatment of locally advanced or metastatic, hormone-receptor (HR)-negative, HER2-negative (triple-negative) breast cancer, in combination with atezolizumab†.
NOTE: Do not substitute nab-paclitaxel with paclitaxel. In a phase 3 clinical trial (the IMpassion131 trial), treatment with atezolizumab and paclitaxel increased the risk of death compared with placebo and paclitaxel in the PD-L1-positive population.
NOTE: Atezolizumab is FDA-approved for this indication in combination with nab-paclitaxel.
Intravenous dosage Adults

100 mg/m2 IV on days 1, 8, and 15, every 28 days until disease progression or unacceptable toxicity. Administer in combination with atezolizumab 840 mg IV every 2 weeks; OR 1,200 mg IV every 3 weeks; OR 1,680 mg IV every 4 weeks until disease progression or unacceptable toxicity. Administer atezolizumab prior to nab-paclitaxel when given on the same day. Atezolizumab and nab-paclitaxel may be discontinued independently of each other. Coadministration of certain drugs may need to be avoided or dosage adjustments may be necessary; review drug interactions. First-line treatment with atezolizumab plus nab-paclitaxel significantly improved progression-free survival (PFS) compared with placebo plus nab-paclitaxel in the first interim analysis of a phase 3 clinical trial (IMpassion130). In the subgroup of patients with PD-L1 expression of 1% or more, PFS was 7.4 months in the atezolizumab arm compared with 4.8 months in the placebo arm; the objective response rate was 53% versus 33% for a median duration of 9.2 months versus 6.2 months, respectively. Overall survival was not significantly improved in the intent-to-treat population, and testing was not performed in the PD-L1 positive subgroup; however, numerical improvements were evident in both groups, and the final analysis may shed more light on this outcome.

For the neoadjuvant treatment of hormone receptor (HR)-negative, HER2-negative (triple-negative) breast cancer, in combination with atezolizumab and sequentially followed by cyclophosphamide plus doxorubicin (dose-dense AC) plus atezolizumab†. Intravenous dosage Adults

125 mg/m2 once weekly in combination with atezolizumab (840 mg IV every 2 weeks) for 12 weeks, followed by atezolizumab 840 mg IV every 2 weeks in combination with doxorubicin (60 mg/m2 IV) plus cyclophosphamide (600 mg/m2 IV) every 2 weeks for 8 weeks (dose-dense AC), followed by surgery. After surgery, continue atezolizumab 1,200 mg IV every 3 weeks for 11 cycles to complete approximately 12 months of atezolizumab therapy. Coadministration of certain drugs may need to be avoided or dosage adjustments may be necessary; review drug interactions. In a randomized, phase 3 clinical trial (IMpassion031), neoadjuvant treatment with atezolizumab plus sequential nab-paclitaxel and AC chemotherapy significantly improved pCR compared with neoadjuvant placebo plus sequential nab-paclitaxel and AC chemotherapy in patients with early TNBC, regardless of PD-L1 status.

For the treatment of locally recurrent unresectable or metastatic, PD-L1 positive (CPS 10 or more), triple negative breast cancer (TNBC), in combination with pembrolizumab†.
NOTE: Select patients for treatment based on the presence of positive PD-L1 expression. Information on FDA-approved tests for the detection of PD-L1 expression in TNBC is available at http://www.fda.gov/CompanionDiagnostics.
NOTE: Pembrolizumab is FDA-approved in combination with carboplatin and gemcitabine for this indication.
Intravenous dosage Adults

100 mg/m2 on days 1, 8, and 15, every 28 days in combination with pembrolizumab (200 mg IV repeated every 3 weeks OR 400 mg IV repeated every 6 weeks until disease progression or up to 24 months in patients without progression); the number of cycles of nab-paclitaxel was not specified.   In a multicenter, double-blind clinical trial (KEYNOTE-355), patients with locally recurrent unresectable or metastatic TNBC who had not been previously treated with chemotherapy in the metastatic setting were randomized to treatment with either pembrolizumab or placebo in combination with paclitaxel, nab-paclitaxel, or gemcitabine plus carboplatin regardless of tumor PD-L1 expression. The addition of pembrolizumab to chemotherapy significantly improved the median progression-free survival (9.7 months vs. 5.6 months) compared with placebo plus chemotherapy in the subgroup of patients with a CPS of 10 or more. The objective response rate was 53% compared with 40%, respectively (complete response, 17% vs. 13%) for a median duration of 19.3 months in the pembrolizumab arm and 7.3 months in the placebo arm.

For the treatment of non-small cell lung cancer (NSCLC). For the first-line treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) in patients who are not candidates for curative surgery or radiation, in combination with carboplatin. Intravenous dosage Adults

100 mg/m2 IV on days 1, 8, and 15 in combination with carboplatin (AUC 6 IV) on day 1 (immediately following the nab-paclitaxel infusion) of each 21-day cycle. The primary endpoint of overall response rate (ORR) assessed by independent radiologic review was significantly improved with nab-paclitaxel plus carboplatin (median number of cycles, 6) compared with solvent-based (sb) paclitaxel plus carboplatin (33% vs. 25%) in patients with previously untreated non-resectable stage IIIB or stage IV NSCLC in a multicenter, randomized, phase 3 trial (n = 1,052). All responding patients in the nab-paclitaxel arm had a partial response (PR); one patient in the sb-paclitaxel arm achieved a complete response, all others had a PR. In a subgroup analysis, the ORR was significantly improved with nab-paclitaxel plus carboplatin in patients with squamous cell histology (41% vs. 24%) but not nonsquamous cell histology (26% vs. 25%). Although treatment with nab-paclitaxel plus carboplatin was not statistically superior compared with sb-paclitaxel plus carboplatin for the secondary endpoints of median progression-free survival (6.3 months vs. 5.8 months) and overall survival (12.1 months vs. 11.2 months), noninferiority was demonstrated.

For the first-line treatment of metastatic squamous non-small cell lung cancer (NSCLC), in combination with carboplatin and pembrolizumab. Intravenous dosage Adults

100 mg/m2 IV on days 1, 8, and 15 and carboplatin (AUC 6 IV on day 1) repeated every 3 weeks for 4 cycles in combination with pembrolizumab (200 mg IV every 3 weeks OR 400 mg IV every 6 weeks until disease progression or up to a maximum of 24 months). Administer pembrolizumab prior to chemotherapy when given on the same day. In a multicenter, randomized, double-blind clinical trial (KEYNOTE-407), treatment with pembrolizumab plus carboplatin and either paclitaxel or nab-paclitaxel (n = 278) significantly improved median overall survival (17.1 months vs. 11.6 months) and progression-free survival (6.4 months vs. 4.8 months) compared with placebo plus carboplatin and paclitaxel/nab-paclitaxel (n = 281) in patients with metastatic squamous NSCLC. The overall response rate was also significantly improved in the pembrolizumab arm (58% vs. 35%), for a median duration of 7.2 months and 4.9 months, respectively.

For the first-line treatment of metastatic nonsquamous non-small cell lung cancer (NSCLC) without EGFR or ALK mutations, in combination with atezolizumab and carboplatin.
NOTE: Atezolizumab is FDA-approved in combination with nab-paclitaxel and carboplatin for this indication.
Intravenous dosage Adults

100 mg/m2 IV on days 1, 8, and 15, every 3 weeks for a maximum of 4 to 6 cycles. Administer in combination with carboplatin (AUC 6 IV on day 1 every 3 weeks for up to 4 to 6 cycles) and atezolizumab (840 mg IV every 2 weeks; OR 1,200 mg IV every 3 weeks; OR 1,680 mg IV every 4 weeks until disease progression or unacceptable toxicity). Administer atezolizumab prior to chemotherapy when given on the same day. Coadministration of certain drugs may need to be avoided or dosage adjustments may be necessary; review drug interactions. First-line treatment of EGFR- and ALK-negative metastatic NSCLC with atezolizumab plus nab-paclitaxel and carboplatin significantly improved median overall survival (18.6 months vs. 13.9 months) and median progression-free survival (7.2 months vs. 6.5 months) compared with nab-paclitaxel and carboplatin alone in a multicenter, randomized, open-label trial (IMpower130). The overall response rate was 46% (complete response [CR], 5%) in the atezolizumab arm compared with 32% (CR, 1%) in the control arm, for a median duration of 10.8 months versus 7.8 months, respectively.

For the first-line treatment of metastatic pancreatic cancer in combination with gemcitabine. Intravenous dosage Adults

125 mg/m2 IV over 30 to 40 minutes on days 1, 8, and 15 followed by gemcitabine (1,000 mg/m2 IV over 30 to 40 minutes on days 1, 8, and 15), every 28 days. In a multinational, randomized, open-label study, nab-paclitaxel plus gemcitabine (n = 431) was compared to gemcitabine 1,000 mg/m2 IV weekly for 7 weeks with a 1 week rest period in cycle 1, and then on days 1, 8, and 15 of each subsequent 28 day cycle (n = 430) until disease progression or unacceptable toxicity in patients with metastatic adenocarcinoma of the pancreas. Median overall survival (8.5 months vs. 6.7 months) and median progression free survival (5.5 months vs. 3.7 months) were significantly improved by the combination of nab-paclitaxel and gemcitabine. Additionally, 23% of patients treated with combination therapy had a confirmed complete or partial overall response, compared to 7% of patients treated with gemcitabine alone.

Mechanism Of Action

Paclitaxel 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.
 
Paclitaxel is hydrophobic and must be formulated in a solvent (Cremophohr EL) to increase solubility and bioavailability. Albumin carries water-insoluble molecules in the human body. Nanoparticle albumin-bound (nab) technology improves tumor penetration via albumin receptor-mediated (gp60) endothelial transcytosis.

Pharmacokinetics

Nab-paclitaxel is administered intravenously. In patients with solid tumors, nab-paclitaxel is extensively protein bound (94%) to plasma proteins and is evenly distributed into blood cells and plasma. In a within-patient comparison study, the fraction of unbound paclitaxel was significantly higher with nab-paclitaxel than with solvent-based paclitaxel (6.2% vs. 2.3%), contributing to significantly higher unbound paclitaxel exposure with nab-paclitaxel compared to solvent-based paclitaxel even when total exposure is comparable. The mean volume of distribution is 1,741 liters, indicating extensive extravascular distribution and/or tissue binding. The volume of distribution is 53% higher for nab-paclitaxel (260 mg/m2 IV over 30 minutes) compared to paclitaxel (175 mg/m2 IV over 3 hours). At 0.31 to 1.15 times the maximum approved recommended dosage, the mean total clearance of paclitaxel ranges from 13 to 30 liters/hour/m2, and the mean terminal elimination half-life ranges from 13 to 27 hours. Clearance was 43% higher for nab-paclitaxel (260 mg/m2 IV over 30 minutes) compared to paclitaxel (175 mg/m2 IV over 3 hours); there were no differences in terminal half-lives. Nab-paclitaxel undergoes extensive nonrenal clearance. After a 30-minute infusion, 4% of a 260 mg/m2 dose of nab-paclitaxel was recovered in the urine as unchanged paclitaxel, with less than 1% as either 6-alpha-hydroxypaclitaxel and 3'-p-hydroxypaclitaxel. Approximately 20% of the total dose is eliminated in the feces.
 
Affected Cytochrome P450 (CYP450) isoenzymes and drug transporters: CYP2C8, CYP3A4
Paclitaxel is primarily metabolized via CYP2C8 to 6-alpha-hydroxypaclitaxel in vitro; it also has 2 minor metabolites via CYP3A4 (3'-p-hydroxypaclitaxel and 6-alpha,3'-para-dihydroxypaclitaxel). In vitro, the metabolism of paclitaxel to 6-alpha-hydroxypaclitaxel was inhibited by several agents (i.e., ketoconazole, verapamil, diltiazem, quinidine, dexamethasone, cyclosporine, teniposide, etoposide, and vincristine), but the concentrations exceeded those found in vivo at therapeutic doses; testosterone, 17-alpha-ethinyl estradiol, retinoic acid, and quercetin also inhibited the in vitro formation of 6-alpha hydroxypaclitaxel. Substrates, inhibitors, and inducers of CYP2C8 and/or CYP3A4 may affect the pharmacokinetics of paclitaxel.

Paclitaxel exhibited linear drug exposure (AUC) across clinical doses ranging from 80 mg/m2 to 300 mg/m2 after IV administration of nab-paclitaxel. In patients with solid tumors, paclitaxel concentrations declined in a biphasic manner after IV administration of nab-paclitaxel, with an initial rapid decline representing distribution to the peripheral compartment and the slower second phase representing drug elimination. The pharmacokinetics of paclitaxel in nab-paclitaxel were independent of the duration of IV infusion.

Pregnancy And Lactation
Pregnancy

Pregnancy should be avoided by females of reproductive potential during nab-paclitaxel treatment and for at least 6 months after the last dose. Although there are no adequately controlled studies in pregnant humans, nab-paclitaxel can cause fetal harm or death when administered during pregnancy based on its mechanism of action and animal studies. Women who are pregnant or who become pregnant while receiving nab-paclitaxel should be apprised of the potential hazard to the fetus. In animal reproduction studies, administration of nab-paclitaxel to pregnant rats during organogenesis resulted in embryo-fetal toxicity at doses approximately 2% of the maximum recommended human dose (MRHD) on a mg/m2 basis. These toxicities included intrauterine mortality, increased resorptions (up to 5-fold), reduced numbers of litters and live fetuses, reduced fetal body weight, and increased fetal anomalies such as soft tissue and skeletal malformations (e.g. eye bulge, folded retina, microphthalmia, dilation of brain ventricles).

Due to the potential for serious adverse reactions in nursing infants from nab-paclitaxel, advise women to discontinue breast-feeding during treatment and for 2 weeks after the final dose. It is not known whether nab-paclitaxel is present in human milk, although many drugs are excreted in human milk.
