Follow applicable special handling and disposal procedures. 1 Calculate the dose of pemetrexed for injection and determine the number of vials needed. Reconstitute pemetrexed for injection to achieve a concentration of 25 mg/mL as follows: Reconstitute each 100-mg vial with 4.2 mL of 0.9% Sodium Chloride Injection, USP (preservative-free) Reconstitute each 500-mg vial with 20 mL of 0.9% Sodium Chloride Injection, USP (preservative-free) Reconstitute each 1-gram vial with 40 mL of 0.9% Sodium Chloride Injection, USP (preservative-free) Do not use calcium-containing solutions for reconstitution. Gently swirl each vial until the powder is completely dissolved. The resulting solution is clear and ranges in color from colorless to yellow or greenish-yellow. FURTHER DILUTION IS REQUIRED prior to administration. Store reconstituted, preservative-free product under refrigerated conditions [2 to 8°C (36 to 46°F)] for no longer than 24 hours from the time of reconstitution. Discard vial after 24 hours. Inspect reconstituted product visually for particulate matter and discoloration prior to further dilution. If particulate matter is observed, discard vial. Withdraw the calculated dose of pemetrexed for injection from the vial(s) and discard vial with any unused portion. Further dilute pemetrexed for injection with 0.9% Sodium Chloride Injection (preservative-free) to achieve a total volume of 100 mL for intravenous infusion. Store diluted, reconstituted product under refrigerated conditions [2 to 8°C (36 to 46°F)] for no more than 24 hours from the time of reconstitution. Discard after 24 hours.

Dosage forms and strengths

For injection: 100 mg, 500 mg or 1 gram pemetrexed as a white to either light yellow or greenish-yellow lyophilized powder in single-dose vials for reconstitution. For Injection: 100 mg, 500 mg or 1 gram lyophilized powder in single-dose vial ( 3 )

Contraindications

Pemetrexed for injection is contraindicated in patients with a history of severe hypersensitivity reaction to pemetrexed [see Adverse Reactions ( 6.1 )]. History of severe hypersensitivity reaction to pemetrexed. ( 4 )

Warnings and precautions

5 WARNINGS AND PRECAUTIONS Myelosuppression: Can cause severe bone marrow suppression resulting in cytopenia and an increased risk of infection. Do not administer pemetrexed for injection when the absolute neutrophil count is less than 1500 cells/mm 3 and platelets are less than 100,000 cells/mm 3 . Initiate supplementation with oral folic acid and intramuscular vitamin B 12 to reduce the severity of hematologic and gastrointestinal toxicity of pemetrexed for injection. ( 2.4 , 5.1 ) Renal Failure: Can cause severe, and sometimes fatal, renal failure. Do not administer when creatinine clearance is less than 45 mL/min. ( 2.3 , 5.2 ) Bullous and Exfoliative Skin Toxicity: Permanently discontinue for severe and life-threatening bullous, blistering or exfoliating skin toxicity. ( 5.3 ) Interstitial Pneumonitis: Withhold for acute onset of new or progressive unexplained pulmonary symptoms. Permanently discontinue if pneumonitis is confirmed. ( 5.4 ) Radiation Recall: Can occur in patients who received radiation weeks to years previously; permanently discontinue for signs of radiation recall. ( 5.5 ) Embryo-Fetal Toxicity: Can cause fetal harm. Advise patients of the potential risk to a fetus and to use effective contraception. ( 5.7 , 8.1 , 8.3 )

5.1 Myelosuppression and Increased Risk of Myelosuppression without Vitamin Supplementation Pemetrexed for injection can cause severe myelosuppression resulting in a requirement for transfusions and which may lead to neutropenic infection. The risk of myelosuppression is increased in patients who do not receive vitamin supplementation. In Study JMCH, incidences of Grade 3-4 neutropenia (38% versus 23%), thrombocytopenia (9% versus 5%), febrile neutropenia (9% versus 0.6%), and neutropenic infection (6% versus 0) were higher in patients who received pemetrexed plus cisplatin without vitamin supplementation as compared to patients who were fully supplemented with folic acid and vitamin B 12 prior to and throughout pemetrexed plus cisplatin treatment. Initiate supplementation with oral folic acid and intramuscular vitamin B 12 prior to the first dose of pemetrexed for injection; continue vitamin supplementation during treatment and for 21 days after the last dose of pemetrexed for injection to reduce the severity of hematologic and gastrointestinal toxicity of pemetrexed for injection [see Dosage and Administration ( 2.4 )] . Obtain a complete blood count at the beginning of each cycle. Do not administer pemetrexed for injection until the ANC is at least 1500 cells/mm 3 and platelet count is at least 100,000 cells/mm 3 . Permanently reduce pemetrexed for injection in patients with an ANC of less than 500 cells/mm 3 or platelet count of less than 50,000 cells/mm 3 in previous cycles [see Dosage and Administration ( 2.6 )] . In Studies JMDB and JMCH, among patients who received vitamin supplementation, incidence of Grade 3-4 neutropenia was 15% and 23%, the incidence of Grade 3-4 anemia was 6% and 4%, and incidence of Grade 3-4 thrombocytopenia was 4% and 5%, respectively. In Study JMCH, 18% of patients in the pemetrexed arm required red blood cell transfusions compared to 7% of patients in the cisplatin arm [see Adverse Reactions ( 6.1 )]. In Studies JMEN, PARAMOUNT, and JMEI, where all patients received vitamin supplementation, incidence of Grade 3-4 neutropenia ranged from 3% to 5%, and incidence of Grade 3-4 anemia ranged from 3% to 5%.

5.2 Renal Failure Pemetrexed for injection can cause severe, and sometimes fatal, renal toxicity. The incidences of renal failure in clinical studies in which patients received pemetrexed with cisplatin were: 2.1% in Study JMDB and 2.2% in Study JMCH. The incidence of renal failure in clinical studies in which patients received pemetrexed as a single agent ranged from 0.4% to 0.6% (Studies JMEN, PARAMOUNT, and JMEI [see Adverse Reactions ( 6.1 )] . Determine creatinine clearance before each dose and periodically monitor renal function during treatment with pemetrexed for injection. Withhold pemetrexed for injection in patients with a creatinine clearance of less than 45 mL/minute [see Dosage and Administration ( 2.3 )] .

5.3 Bullous and Exfoliative Skin Toxicity Serious and sometimes fatal, bullous, blistering and exfoliative skin toxicity, including cases suggestive of Stevens-Johnson Syndrome/Toxic epidermal necrolysis can occur with pemetrexed for injection. Permanently discontinue pemetrexed for injection for severe and life-threatening bullous, blistering or exfoliating skin toxicity.

5.4 Interstitial Pneumonitis Serious interstitial pneumonitis, including fatal cases, can occur with pemetrexed for injection treatment. Withhold pemetrexed for injection for acute onset of new or progressive unexplained pulmonary symptoms such as dyspnea, cough, or fever pending diagnostic evaluation. If pneumonitis is confirmed, permanently discontinue pemetrexed for injection.

5.5 Radiation Recall Radiation recall can occur with pemetrexed for injection in patients who have received radiation weeks to years previously. Monitor patients for inflammation or blistering in areas of previous radiation treatment. Permanently discontinue pemetrexed for injection for signs of radiation recall.

5.6 Increased Risk of Toxicity with Ibuprofen in Patients with Renal Impairment Exposure to pemetrexed for injection is increased in patients with mild to moderate renal impairment who take concomitant ibuprofen, increasing the risks of adverse reactions of pemetrexed for injection. In patients with creatinine clearances between 45 mL/min and 79 mL/min, avoid administration of ibuprofen for 2 days before, the day of, and 2 days following administration of pemetrexed for injection. If concomitant ibuprofen use cannot be avoided, monitor patients more frequently for pemetrexed for injection adverse reactions, including myelosuppression, renal, and gastrointestinal toxicity [see Dosage and Administration ( 2.5 ), Drug Interactions ( 7 ), and Clinical Pharmacology ( 12.3 )] .

5.7 Embryo-Fetal Toxicity Based on findings from animal studies and its mechanism of action, pemetrexed for injection can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, intravenous administration of pemetrexed to pregnant mice during the period of organogenesis was teratogenic, resulting in developmental delays and increased malformations at doses lower than the recommended human dose of 500 mg/m 2 . Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with pemetrexed for injection and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with pemetrexed for injection and for 3 months after the last dose [see Use in Specific Populations ( 8.1 , 8.3 ) and Clinical Pharmacology ( 12.1 )] .

Drug interactions

Ibuprofen increased risk of pemetrexed for injection toxicity in patients with mild to moderate renal impairment. Modify the ibuprofen dosage as recommended for patients with a creatinine clearance between 45 mL/min and 79 mL/min. ( 2.5 , 5.6 , 7 ) Effects of Ibuprofen on Pemetrexed Ibuprofen increases exposure (AUC) of pemetrexed [see Clinical Pharmacology ( 12.3 )] . In patients with creatinine clearance between 45 mL/min and 79 mL/min: Avoid administration of ibuprofen for 2 days before, the day of, and 2 days following administration of pemetrexed for injection [see Dosage and Administration ( 2.5 )] . Monitor patients more frequently for myelosuppression, renal, and gastrointestinal toxicity, if concomitant administration of ibuprofen cannot be avoided.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reactions rates cannot be directly compared to rates in other clinical trials and may not reflect the rates observed in clinical practice. In clinical trials, the most common adverse reactions (incidence ≥20%) of pemetrexed, when administered as a single agent, are fatigue, nausea, and anorexia. The most common adverse reactions (incidence ≥20%) of pemetrexed, when administered in combination with cisplatin are vomiting, neutropenia, anemia, stomatitis/pharyngitis, thrombocytopenia, and constipation. The most common adverse reactions (incidence ≥20%) of pemetrexed, when administered in combination with pembrolizumab and platinum chemotherapy, are fatigue/asthenia, nausea, constipation, diarrhea, decreased appetite, rash, vomiting, cough, dyspnea, and pyrexia. Non-Squamous NSCLC First-line Treatment of Metastatic Non-squamous NSCLC with Pembrolizumab and Platinum Chemotherapy The safety of pemetrexed, in combination with pembrolizumab and investigator's choice of platinum (either carboplatin or cisplatin), was investigated in Study KEYNOTE-189, a multicenter, double-blind, randomized (2:1), active-controlled trial in patients with previously untreated, metastatic non-squamous NSCLC with no EGFR or ALK genomic tumor aberrations. A total of 607 patients received pemetrexed, pembrolizumab, and platinum every 3 weeks for 4 cycles followed by pemetrexed and pembrolizumab (n=405), or placebo, pemetrexed, and platinum every 3 weeks for 4 cycles followed by placebo and pemetrexed (n=202). Patients with autoimmune disease that required systemic therapy within 2 years of treatment; a medical condition that required immunosuppression; or who had received more than 30 Gy of thoracic radiation within the prior 26 weeks were ineligible [see Clinical Studies ( 14.1 )] . The median duration of exposure to pemetrexed was 7.2 months (range: 1 day to 1.7 years). Seventy-two percent of patients received carboplatin. The study population characteristics were: median age of 64 years (range: 34 to 84), 49% age 65 years or older, 59% male, 94% White and 3% Asian, and 18% with history of brain metastases at baseline. Pemetrexed was discontinued for adverse reactions in 23% of patients in the pemetrexed, pembrolizumab, and platinum arm. The most common adverse reactions resulting in discontinuation of pemetrexed in this arm were acute kidney injury (3%) and pneumonitis (2%). Adverse reactions leading to interruption of pemetrexed occurred in 49% of patients in the pemetrexed, pembrolizumab, and platinum arm. The most common adverse reactions or laboratory abnormalities leading to interruption of pemetrexed in this arm (≥2%) were neutropenia (12%), anemia (7%), asthenia (4%), pneumonia (4%), thrombocytopenia (4%), increased blood creatinine (3%), diarrhea (3%), and fatigue (3%). Table 2 summarizes the adverse reactions that occurred in ≥20% of patients treated with pemetrexed, pembrolizumab, and platinum.

Patients received either pemetrexed 500 mg/m 2 intravenously and cisplatin 75 mg/m 2 intravenously on Day 1 of each 21-day cycle (n=839) or gemcitabine 1250 mg/m 2 intravenously on Days 1 and 8 and cisplatin 75 mg/m 2 intravenously on Day 1 of each 21-day cycle (n=830). All patients were fully supplemented with folic acid and vitamin B 12 . Study JMDB excluded patients with an Eastern Cooperative Oncology Group Performance Status (ECOG PS of 2 or greater), uncontrolled third-space fluid retention, inadequate bone marrow reserve and organ function, or a calculated creatinine clearance less than 45 mL/min. Patients unable to stop using aspirin or other non-steroidal anti-inflammatory drugs or unable to take folic acid, vitamin B 12 or corticosteroids were also excluded from the study. The data described below reflect exposure to pemetrexed plus cisplatin in 839 patients in Study JMDB. Median age was 61 years (range 26-83 years); 70% of patients were men; 78% were White, 16% were Asian, 2.9% were Hispanic or Latino, 2.1% were Black or African American, and <1% were other ethnicities; 36% had an ECOG PS 0. Patients received a median of 5 cycles of pemetrexed. Table 4 provides the frequency and severity of adverse reactions that occurred in ≥5% of 839 patients receiving pemetrexed in combination with cisplatin in Study JMDB. Study JMDB was not designed to demonstrate a statistically significant reduction in adverse reaction rates for pemetrexed, as compared to the control arm, for any specified adverse reaction listed in Table 4 .

Patients received either pemetrexed 500 mg/m 2 or matching placebo intravenously every 21 days until disease progression or unacceptable toxicity. Patients in both study arms were fully supplemented with folic acid and vitamin B 12 . Study JMEN excluded patients with an ECOG PS of 2 or greater, uncontrolled third-space fluid retention, inadequate bone marrow reserve and organ function, or a calculated creatinine clearance less than 45 mL/min. Patients unable to stop using aspirin or other non-steroidal anti-inflammatory drugs or unable to take folic acid, vitamin B 12 or corticosteroids were also excluded from the study. The data described below reflect exposure to pemetrexed in 438 patients in Study JMEN. Median age was 61 years (range 26-83 years), 73% of patients were men; 65% were White, 31% were Asian, 2.9% were Hispanic or Latino, and <2% were other ethnicities; 39% had an ECOG PS 0. Patients received a median of 5 cycles of pemetrexed and a relative dose intensity of pemetrexed of 96%. Approximately half the patients (48%) completed at least six, 21-day cycles and 23% completed ten or more 21-day cycles of pemetrexed.

Patients were randomized to receive pemetrexed 500 mg/m 2 or matching placebo intravenously on Day 1 of each 21-day cycle until disease progression or unacceptable toxicity. Patients in both study arms received folic acid and vitamin B 12 supplementation. PARAMOUNT excluded patients with an ECOG PS of 2 or greater, uncontrolled third-space fluid retention, inadequate bone marrow reserve and organ function, or a calculated creatinine clearance less than 45 mL/min. Patients unable to stop using aspirin or other non-steroidal anti-inflammatory drugs or unable to take folic acid, vitamin B 12 or corticosteroids were also excluded from the study. The data described below reflect exposure to pemetrexed in 333 patients in PARAMOUNT. Median age was 61 years (range 32 to 83 years); 58% of patients were men; 94% were White, 4.8% were Asian, and <1% were Black or African American; 36% had an ECOG PS 0. The median number of maintenance cycles was 4 for pemetrexed and placebo arms. Dose reductions for adverse reactions occurred in 3.3% of patients in the pemetrexed arm and 0.6% in the placebo arm. Dose delays for adverse reactions occurred in 22% of patients in the pemetrexed arm and 16% in the placebo arm.

Patients received pemetrexed 500 mg/m 2 intravenously or docetaxel 75 mg/m 2 intravenously on Day 1 of each 21-day cycle. All patients on the pemetrexed arm received folic acid and vitamin B 12 supplementation. Study JMEI excluded patients with an ECOG PS of 3 or greater, uncontrolled third-space fluid retention, inadequate bone marrow reserve and organ function, or a calculated creatinine clearance less than 45 mL/min. Patients unable to discontinue aspirin or other non-steroidal anti-inflammatory drugs or unable to take folic acid, vitamin B 12 or corticosteroids were also excluded from the study. The data described below reflect exposure to pemetrexed in 265 patients in Study JMEI. Median age was 58 years (range 22 to 87 years); 73% of patients were men; 70% were White, 24% were Asian, 2.6% were Black or African American, 1.8% were Hispanic or Latino, and <2% were other ethnicities; 19% had an ECOG PS 0. Table 7 provides the frequency and severity of adverse reactions reported in ≥5% of the 265 pemetrexed-treated patients in Study JMEI.

Patients received pemetrexed 500 mg/m 2 intravenously in combination with cisplatin 75 mg/m 2 intravenously on Day 1 of each 21-day cycle or cisplatin 75 mg/m 2 intravenously on Day 1 of each 21-day cycle administered until disease progression or unacceptable toxicity. Safety was assessed in 226 patients who received at least one dose of pemetrexed in combination with cisplatin and 222 patients who received at least one dose of cisplatin alone. Among 226 patients who received pemetrexed in combination with cisplatin, 74% (n=168) received full supplementation with folic acid and vitamin B 12 during study therapy, 14% (n=32) were never supplemented, and 12% (n=26) were partially supplemented. Study JMCH excluded patients with Karnofsky Performance Scale (KPS) of less than 70, inadequate bone marrow reserve and organ function, or a calculated creatinine clearance less than 45 mL/min. Patients unable to stop using aspirin or other non-steroidal anti-inflammatory drugs were also excluded from the study. The data described below reflect exposure to pemetrexed in 168 patients that were fully supplemented with folic acid and vitamin B 12 . Median age was 60 years (range 19 to 85 years); 82% were men; 92% were White, 5% were Hispanic or Latino, 3.0% were Asian, and <1% were other ethnicities; 54% had KPS of 90-100. The median number of treatment cycles administered was 6 in the pemetrexed/cisplatin fully supplemented group and 2 in the pemetrexed/cisplatin never supplemented group. Patients receiving pemetrexed in the fully supplemented group had a relative dose intensity of 93% of the protocol-specified pemetrexed dose intensity. The most common adverse reaction resulting in dose delay was neutropenia. Table 8 provides the frequency and severity of adverse reactions ≥5% in the subgroup of pemetrexed-treated patients who were fully vitamin supplemented in Study JMCH.

Overdosage

No drugs are approved for the treatment of pemetrexed for injection overdose. Based on animal studies, administration of leucovorin may mitigate the toxicities of pemetrexed for injection overdosage. It is not known whether pemetrexed is dialyzable.

Use in specific populations

Lactation: Advise not to breastfeed. ( 8.2 )

8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action, pemetrexed for injection can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12.1 )] . There are no available data on pemetrexed for injection use in pregnant women. In animal reproduction studies, intravenous administration of pemetrexed to pregnant mice during the period of organogenesis was teratogenic, resulting in developmental delays and malformations at doses lower than the recommended human dose of 500 mg/m 2 [see Data ] . Advise pregnant women of the potential risk to a fetus [see Use in Special Populations ( 8.3 )] . 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 Pemetrexed was teratogenic in mice. Daily dosing of pemetrexed by intravenous injection to pregnant mice during the period of organogenesis increased the incidence of fetal malformations (cleft palate; protruding tongue; enlarged or misshaped kidney; and fused lumbar vertebra) at doses (based on BSA) 0.03 times the human dose of 500 mg/m 2 . At doses, based on BSA, greater than or equal to 0.0012 times the 500 mg/m 2 human dose, pemetrexed administration resulted in dose-dependent increases in developmental delays (incomplete ossification of talus and skull bone; and decreased fetal weight).

8.2 Lactation Risk Summary There is no information regarding the presence of pemetrexed or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. Because of the potential for serious adverse reactions in breastfed infants from pemetrexed for injection, advise women not to breastfeed during treatment with pemetrexed for injection and for one week after the last dose.

8.3 Females and Males of Reproductive Potential Based on animal data pemetrexed for injection can cause malformations and developmental delays when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . Pregnancy Testing Verify pregnancy status of females of reproductive potential prior to initiating Pemetrexed Injection [see Use in Specific Populations ( 8.1 )] . Contraception Females Because of the potential for genotoxicity, advise females of reproductive potential to use effective contraception during treatment with pemetrexed for injection and for 6 months after the last dose. Males Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use effective contraception during treatment with pemetrexed for injection and for 3 months after the last dose [see Nonclinical Toxicology ( 13.1 )] . Infertility Males pemetrexed for injection may impair fertility in males of reproductive potential. It is not known whether these effects on fertility are reversible [see Nonclinical Toxicology ( 13.1 )] . Infertility Males Pemetrexed for injection may impair fertility in males of reproductive potential. It is not known whether these effects on fertility are reversible [see Nonclinical Toxicology ( 13.1 )] .

8.4 Pediatric Use The safety and effectiveness of pemetrexed for injection in pediatric patients have not been established. The safety and pharmacokinetics of pemetrexed for injection were evaluated in two clinical studies conducted in pediatric patients with recurrent solid tumors (NCT00070473 N=32 and NCT00520936 N=72). Patients in both studies received concomitant vitamin B12 and folic acid supplementation and dexamethasone. No tumor responses were observed. Adverse reactions observed in pediatric patients were similar to those observed in adults. Single-dose pharmacokinetics of pemetrexed for injection were evaluated in 22 patients age 4 to 18 years enrolled in NCT00070473 were within range of values in adults.

8.5 Geriatric Use Of the 3,946 patients enrolled in clinical studies of pemetrexed, 34% were 65 and over and 4% were 75 and over. No overall differences in effectiveness were observed between these patients and younger patients. The incidences of Grade 3-4 anemia, fatigue, thrombocytopenia, hypertension, and neutropenia were higher in patients 65 years of age and older as compared to younger patients: in at least one of five randomized clinical trials. [see Adverse Reactions ( 6.1 ) and Clinical Studies ( 14.1 , 14.2 )].

8.6 Patients with Renal Impairment Pemetrexed is primarily excreted by the kidneys. Decreased renal function results in reduced clearance and greater exposure (AUC) to pemetrexed compared with patients with normal renal function [Warnings and Precautions ( 5.2 , 5.6 ) and Clinical Pharmacology ( 12.3 )] . No dose is recommended for patients with creatinine clearance less than 45 mL/min [see Dosage and Administration ( 2.3 )].

Clinical pharmacology

12.1 Mechanism of Action Pemetrexed is a folate analog metabolic inhibitor that disrupts folate-dependent metabolic processes essential for cell replication. In vitro studies show that pemetrexed inhibits thymidylate synthase (TS), dihydrofolate reductase, and glycinamide ribonucleotide formyltransferase (GARFT), which are folate-dependent enzymes involved in the de novo biosynthesis of thymidine and purine nucleotides. Pemetrexed is taken into cells by membrane carriers such as the reduced folate carrier and membrane folate binding protein transport systems. Once in the cell, pemetrexed is converted to polyglutamate forms by the enzyme folylpolyglutamate synthetase. The polyglutamate forms are retained in cells and are inhibitors of TS and GARFT.

12.2 Pharmacodynamics Pemetrexed inhibited the in vitro growth of mesothelioma cell lines (MSTO-211H, NCI-H2052) and showed synergistic effects when combined with cisplatin. Based on population pharmacodynamic analyses, the depth of the absolute neutrophil counts (ANC) nadir correlates with the systemic exposure to pemetrexed and supplementation with folic acid and vitamin B 12 . There is no cumulative effect of pemetrexed exposure on ANC nadir over multiple treatment cycles.

12.3 Pharmacokinetics Absorption The pharmacokinetics of pemetrexed when pemetrexed was administered as a single agent in doses ranging from 0.2 to 838 mg/m 2 infused over a 10-minute period have been evaluated in 426 cancer patients with a variety of solid tumors. Pemetrexed total systemic exposure (AUC) and maximum plasma concentration (C max ) increased proportionally with increase of dose. The pharmacokinetics of pemetrexed did not change over multiple treatment cycles. Distribution Pemetrexed has a steady-state volume of distribution of 16.1 liters. In vitro studies indicated that pemetrexed is 81% bound to plasma proteins. Elimination The total systemic clearance of pemetrexed is 91.8 mL/min and the elimination half-life of pemetrexed is 3.5 hours in patients with normal renal function (creatinine clearance of 90 mL/min). As renal function decreases, the clearance of pemetrexed decreases and exposure (AUC) of pemetrexed increases. Metabolism Pemetrexed is not metabolized to an appreciable extent. Excretion Pemetrexed is primarily eliminated in the urine, with 70% to 90% of the dose recovered unchanged within the first 24 hours following administration. In vitro studies indicated that pemetrexed is a substrate of OAT3 (organic anion transporter 3), a transporter that is involved in the active secretion of pemetrexed. Specific Populations Age (26 to 80 years) and sex had no clinically meaningful effect on the systemic exposure of pemetrexed based on population pharmacokinetic analyses. Racial Groups The pharmacokinetics of pemetrexed were similar in Whites and Blacks or African Americans. Insufficient data are available for other ethnic groups. Patients with Hepatic Impairment Pemetrexed has not been formally studied in patients with hepatic impairment. No effect of elevated AST, ALT, or total bilirubin on the PK of pemetrexed was observed in clinical studies. Patients with Renal Impairment Pharmacokinetic analyses of pemetrexed included 127 patients with impaired renal function. Plasma clearance of pemetrexed decreases as renal function decreases, with a resultant increase in systemic exposure. Patients with creatinine clearances of 45, 50, and 80 mL/min had 65%, 54%, and 13% increases, respectively in systemic exposure (AUC) compared to patients with creatinine clearance of 100 mL/min [see Dosage and Administration ( 2.3 ) and Warnings and Precautions ( 5.2 )] . Third-Space Fluid The pemetrexed plasma concentrations in patients with various solid tumors with stable, mild to moderate third-space fluid were comparable to those observed in patients without third space fluid collections. The effect of severe third space fluid on pharmacokinetics is not known. Drug Interaction Studies Drugs Inhibiting OAT3 Transporter Ibuprofen, an OAT3 inhibitor, administered at 400 mg four times a day decreased the clearance of pemetrexed and increased its exposure (AUC) by approximately 20% in patients with normal renal function (creatinine clearance >80 mL/min). In Vitro Studies Pemetrexed is a substrate for OAT3. Ibuprofen, an OAT3 inhibitor inhibited the uptake of pemetrexed in OAT3-expressing cell cultures with an average [I u ]/IC 50 ratio of 0.38. In vitro data predict that at clinically relevant concentrations, other NSAIDs (naproxen, diclofenac, celecoxib) would not inhibit the uptake of pemetrexed by OAT3 and would not increase the AUC of pemetrexed to a clinically significant extent. [see Drug Interactions ( 7 )] . Pemetrexed is a substrate for OAT4. In vitro, ibuprofen and other NSAIDs (naproxen, diclofenac, celecoxib) are not inhibitors of OAT4 at clinically relevant concentrations. Aspirin Aspirin, administered in low to moderate doses (325 mg every 6 hours), does not affect the pharmacokinetics of pemetrexed. Cisplatin Cisplatin does not affect the pharmacokinetics of pemetrexed and the pharmacokinetics of total platinum are unaltered by pemetrexed. Vitamins Neither folic acid nor vitamin B 12 affect the pharmacokinetics of pemetrexed. Drugs Metabolized by Cytochrome P450 Enzymes In vitro studies suggest that pemetrexed does not inhibit the clearance of drugs metabolized by CYP3A, CYP2D6, CYP2C9, and CYP1A2.

In Vitro Studies Pemetrexed is a substrate for OAT3. Ibuprofen, an OAT3 inhibitor inhibited the uptake of pemetrexed in OAT3-expressing cell cultures with an average [I u ]/IC 50 ratio of 0.38. In vitro data predict that at clinically relevant concentrations, other NSAIDs (naproxen, diclofenac, celecoxib) would not inhibit the uptake of pemetrexed by OAT3 and would not increase the AUC of pemetrexed to a clinically significant extent. [see Drug Interactions ( 7 )] . Pemetrexed is a substrate for OAT4. In vitro, ibuprofen and other NSAIDs (naproxen, diclofenac, celecoxib) are not inhibitors of OAT4 at clinically relevant concentrations. Aspirin Aspirin, administered in low to moderate doses (325 mg every 6 hours), does not affect the pharmacokinetics of pemetrexed. Cisplatin Cisplatin does not affect the pharmacokinetics of pemetrexed and the pharmacokinetics of total platinum are unaltered by pemetrexed. Vitamins Neither folic acid nor vitamin B 12 affect the pharmacokinetics of pemetrexed. Drugs Metabolized by Cytochrome P450 Enzymes In vitro studies suggest that pemetrexed does not inhibit the clearance of drugs metabolized by CYP3A, CYP2D6, CYP2C9, and CYP1A2.

Carcinogenesis, mutagenesis, fertility

, Mutagenesis, Impairment of Fertility No carcinogenicity studies have been conducted with pemetrexed. Pemetrexed was clastogenic in an in vivo micronucleus assay in mouse bone marrow but was not mutagenic in multiple in vitro tests (Ames assay, Chinese Hamster Ovary cell assay). Pemetrexed administered intraperitoneally at doses of ≥0.1 mg/kg/day to male mice (approximately 0.0006 times the recommended human dose based on BSA) resulted in reduced fertility, hypospermia, and testicular atrophy.

Information for patients
