In clinical trials, the most common adverse reactions (incidence ≥20%) of Pemetrexed for Injection, when administered as a single agent, are fatigue, nausea, and anorexia. The most common adverse reactions (incidence ≥20%) of Pemetrexed for Injection, when administered in combination with cisplatin are vomiting, neutropenia, anemia, stomatitis/pharyngitis, thrombocytopenia, and constipation. The most common adverse reactions (incidence ≥20%) of Pemetrexed for Injection, 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 for Injection, 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 for Injection, pembrolizumab, and platinum every 3 weeks for 4 cycles followed by Pemetrexed for Injection and pembrolizumab (n=405), or placebo, Pemetrexed for Injection, and platinum every 3 weeks for 4 cycles followed by placebo and Pemetrexed for Injection (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 for Injection 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 for Injection was discontinued for adverse reactions in 23% of patients in the Pemetrexed for Injection, pembrolizumab, and platinum arm. The most common adverse reactions resulting in discontinuation of Pemetrexed for Injection in this arm were acute kidney injury (3%) and pneumonitis (2%). Adverse reactions leading to interruption of Pemetrexed for Injection occurred in 49% of patients in the Pemetrexed for Injection, pembrolizumab, and platinum arm. The most common adverse reactions or laboratory abnormalities leading to interruption of Pemetrexed for Injection 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 for Injection, pembrolizumab, and platinum.

Patients received either Pemetrexed for Injection 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 for Injection 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 for Injection. Table 4 provides the frequency and severity of adverse reactions that occurred in ≥5% of 839 patients receiving Pemetrexed for Injection in combination with cisplatin in Study JMDB. Study JMDB was not designed to demonstrate a statistically significant reduction in adverse reaction rates for Pemetrexed for Injection, as compared to the control arm, for any specified adverse reaction listed in Table 4 .

Patients received either Pemetrexed for Injection 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 for Injection 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 for Injection and a relative dose intensity of Pemetrexed for Injection 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 for Injection. Table 5 provides the frequency and severity of adverse reactions reported in ≥5% of the 438 Pemetrexed for Injection-treated patients in Study JMEN.

Patients received Pemetrexed for Injection 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 for Injection in combination with cisplatin and 222 patients who received at least one dose of cisplatin alone. Among 226 patients who received Pemetrexed for Injection 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 for Injection 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 for Injection/cisplatin fully supplemented group and 2 in the Pemetrexed for Injection/cisplatin never supplemented group. Patients receiving Pemetrexed for Injection in the fully supplemented group had a relative dose intensity of 93% of the protocol-specified Pemetrexed for Injection 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 for Injection-treated patients who were fully vitamin supplemented in Study JMCH. Study JMCH was not designed to demonstrate a statistically significant reduction in adverse reaction rates for Pemetrexed for Injection, as compared to the control arm, for any specified adverse reaction listed in the table below.

    Drug Interactions

    7 DRUG INTERACTIONS 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. 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 )

    Clinical Pharmacology

    12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Pemetrexed for Injection 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 for Injection 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.

    Clinical Studies

    14 CLINICAL STUDIES 14.1 Non-Squamous NSCLC Initial Treatment in Combination with Pembrolizumab and Platinum The efficacy of Pemetrexed for Injection in combination with pembrolizumab and platinum chemotherapy was investigated in Study KEYNOTE-189 (NCT02578680), a randomized, multicenter, double-blind, active-controlled trial conducted in patients with metastatic non-squamous NSCLC, regardless of PD-L1 tumor expression status, who had not previously received systemic therapy for metastatic disease and in whom there were no EGFR or ALK genomic tumor aberrations. 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. Randomization was stratified by smoking status (never versus former/current), choice of platinum (cisplatin versus carboplatin), and tumor PD-L1 status (TPS <1% [negative] versus TPS ≥1%). Patients were randomized (2:1) to one of the following treatment arms: • Pemetrexed for Injection 500 mg/m2, pembrolizumab 200 mg, and investigator’s choice of cisplatin 75 mg/m2 or carboplatin AUC 5 mg/mL/min intravenously on Day 1 of each 21-day cycle for 4 cycles followed by Pemetrexed for Injection 500 mg/m2 and pembrolizumab 200 mg intravenously every 3 weeks. Pemetrexed for Injection was administered after pembrolizumab and prior to platinum chemotherapy on Day 1. • Placebo, Pemetrexed for Injection 500 mg/m2, and investigator’s choice of cisplatin 75 mg/m2 or carboplatin AUC 5 mg/mL/min intravenously on Day 1 of each 21-day cycle for 4 cycles followed by placebo and Pemetrexed for Injection 500 mg/m2 intravenously every 3 weeks. Treatment with Pemetrexed for Injection continued until RECIST v1.1 (modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ)-defined progression of disease as determined by the investigator or unacceptable toxicity. Patients randomized to placebo, Pemetrexed for Injection, and platinum chemotherapy were offered pembrolizumab as a single agent at the time of disease progression. Assessment of tumor status was performed at Week 6, Week 12, and then every 9 weeks thereafter. The main efficacy outcome measures were OS and PFS as assessed by BICR RECIST v1.1, modified to follow a maximum of 10 target lesions and a maximum of five target lesions per organ. Additional efficacy outcome measures were ORR and duration of response, as assessed by the BICR according to RECIST v1.1, modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. A total of 616 patients were randomized: 410 patients to the Pemetrexed for Injection, pembrolizumab, and platinum chemotherapy arm and 206 to the placebo, Pemetrexed for Injection, and platinum chemotherapy arm. The study population characteristics were: median age of 64 years (range: 34 to 84); 49% age 65 or older; 59% male; 94% White and 3% Asian; 56% ECOG performance status of 1; and 18% with history of brain metastases. Thirty-one percent had tumor PD-L1 expression TPS <1%. Seventy-two percent received carboplatin and 12% were never smokers. A total of 85 patients in the placebo, Pemetrexed for Injection, and chemotherapy arm received an anti-PD-1/PD-L1 monoclonal antibody at the time of disease progression. The trial demonstrated a statistically significant improvement in OS and PFS for patients randomized to Pemetrexed for Injection in combination with pembrolizumab and platinum chemotherapy compared with placebo, Pemetrexed for Injection, and platinum chemotherapy (see Table 10 and Figure 1 ).

Figure 1: Kaplan-Meier Curve for Overall Survival in KEYNOTE-189* *Based on the protocol-specified final OS analysis Initial Treatment in Combination with Cisplatin The efficacy of Pemetrexed for Injection was evaluated in Study JMDB (NCT00087711), a multi-center, randomized (1:1), open-label study conducted in 1725 chemotherapy-naive patients with Stage IIIb/IV NSCLC. Patients were randomized to receive Pemetrexed for Injection with cisplatin or gemcitabine with cisplatin. Randomization was stratified by Eastern Cooperative Oncology Group Performance Status (ECOG PS 0 versus 1), gender, disease stage, basis for pathological diagnosis (histopathological/cytopathological), history of brain metastases, and investigative center. Pemetrexed for Injection was administered intravenously over 10 minutes at a dose of 500 mg/m 2 on Day 1 of each 21-day cycle. Cisplatin was administered intravenously at a dose of 75 mg/m 2 approximately 30 minutes after Pemetrexed for Injection administration on Day 1 of each cycle, gemcitabine was administered at a dose of 1250 mg/m 2 on Day 1 and Day 8, and cisplatin was administered intravenously at a dose of 75 mg/m 2 approximately 30 minutes after administration of gemcitabine, on Day 1 of each 21-day cycle. Treatment was administered up to a total of 6 cycles; patients in both arms received folic acid, vitamin B 12 , and dexamethasone [see Dosage and Administration (2.4) ] . The primary efficacy outcome measure was overall survival. A total of 1725 patients were enrolled with 862 patients randomized to Pemetrexed for Injection in combination with cisplatin and 863 patients to gemcitabine in combination with cisplatin. The median age was 61 years (range 26-83 years), 70% were male, 78% were White, 17% were Asian, 2.9% were Hispanic or Latino, and 2.1% were Black or African American, and <1% were other ethnicities. Among patients for whom ECOG PS (n=1722) and smoking history (n=1516) were collected, 65% had an ECOG PS of 1, 36% had an ECOG PS of 0, and 84% were smokers. For tumor characteristics, 73% had non-squamous NSCLC and 27% had squamous NSCLC; 76% had Stage IV disease. Among 1252 patients with non-squamous NSCLC histology, 68% had a diagnosis of adenocarcinoma, 12% had large cell histology and 20% had other histologic subtypes. Efficacy results in Study JMDB are presented in Table 11 and Figure 2 .

Patients were randomized to receive Pemetrexed for Injection 500 mg/m 2 intravenously every 21 days or placebo until disease progression or intolerable toxicity. Patients in both study arms received folic acid, vitamin B 12 , and dexamethasone [see Dosage and Administration (2.4) ]. Randomization was carried out using a minimization approach [Pocock and Simon (1975)] using the following factors: gender, ECOG PS (0 versus 1), response to prior chemotherapy (complete or partial response versus stable disease), history of brain metastases (yes versus no), non-platinum component of induction therapy (docetaxel versus gemcitabine versus paclitaxel), and disease stage (IIIb versus IV). The major efficacy outcome measures were progression-free survival based on assessment by independent review and overall survival; both were measured from the date of randomization in Study JMEN. A total of 663 patients were enrolled with 441 patients randomized to Pemetrexed for Injection and 222 patients randomized to placebo. The median age was 61 years (range 26-83 years); 73% were male; 65% were White, 32% were Asian, 2.9% were Hispanic or Latino, and <2% were other ethnicities; 60% had an ECOG PS of 1; and 73% were current or former smokers. Median time from initiation of platinum-based chemotherapy to randomization was 3.3 months (range 1.6 to 5.1 months) and 49% of the population achieved a partial or complete response to first-line, platinum-based chemotherapy. With regard to tumor characteristics, 81% had Stage IV disease, 73% had non-squamous NSCLC and 27% had squamous NSCLC. Among the 481 patients with non-squamous NSCLC, 68% had adenocarcinoma, 4% had large cell, and 28% had other histologies. Efficacy results are presented in Table 13 and Figure 5 .

Patients were required to have an ECOG PS of 0 or 1. Patients were randomized to receive Pemetrexed for Injection 500 mg/m 2 intravenously every 21 days or placebo until disease progression. Randomization was stratified by response to Pemetrexed for Injection in combination with cisplatin induction therapy (CR or PR versus SD), disease stage (IIIb versus IV), and ECOG PS (0 versus 1). Patients in both arms received folic acid, vitamin B 12 , and dexamethasone. The main efficacy outcome measure was investigator-assessed progression-free survival (PFS) and an additional efficacy outcome measure was overall survival (OS); PFS and OS were measured from the time of randomization. A total of 539 patients were enrolled with 359 patients randomized to Pemetrexed for Injection and 180 patients randomized to placebo. The median age was 61 years (range 32 to 83 years); 58% were male; 95% were White, 4.5% were Asian, and <1% were Black or African American; 67% had an ECOG PS of 1; 78% were current or former smokers; and 43% of the population achieved a partial or complete response to first-line, platinum-based chemotherapy. With regard to tumor characteristics, 91% had Stage IV disease, 87% had adenocarcinoma, 7% had large cell, and 6% had other histologies.

Patients were randomized to receive Pemetrexed for Injection 500 mg/m 2 intravenously or docetaxel 75 mg/m 2 as a 1-hour intravenous infusion once every 21 days. Patients randomized to Pemetrexed for Injection also received folic acid and vitamin B 12 . The study was designed to show that overall survival with Pemetrexed for Injection was non-inferior to docetaxel, as the major efficacy outcome measure, and that overall survival was superior for patients randomized to Pemetrexed for Injection compared to docetaxel, as a secondary outcome measure. A total of 571 patients were enrolled with 283 patients randomized to Pemetrexed for Injection and 288 patients randomized to docetaxel. The median age was 58 years (range 22 to 87 years); 72% were male; 71% were White, 24% were Asian, 2.8% were Black or African American, 1.8% were Hispanic or Latino, and <2% were other ethnicities; 88% had an ECOG PS of 0 or 1. With regard to tumor characteristics, 75% had Stage IV disease; 53% had adenocarcinoma, 30% had squamous histology; 8% large cell; and 9% had other histologic subtypes of NSCLC. The efficacy results in the overall population and in subgroup analyses based on histologic subtype are provided in Tables 16 and 17 , respectively. Study JMEI did not show an improvement in overall survival in the intent-to-treat population. In subgroup analyses, there was no evidence of a treatment effect on survival in patients with squamous NSCLC; the absence of a treatment effect in patients with NSCLC of squamous histology was also observed Studies JMDB and JMEN [see Clinical Studies (14.1) ].

Patients were randomized (n=456) to receive Pemetrexed for Injection 500 mg/m 2 intravenously over 10 minutes followed 30 minutes later by cisplatin 75 mg/m 2 intravenously over two hours on Day 1 of each 21-day cycle or to receive cisplatin 75 mg/m 2 intravenously over 2 hours on Day 1 of each 21-day cycle; treatment continued until disease progression or intolerable toxicity. The study was modified after randomization and treatment of 117 patients to require that all patients receive folic acid 350 mcg to 1000 mcg daily beginning 1 to 3 weeks prior to the first dose of Pemetrexed for Injection and continuing until 1 to 3 weeks after the last dose, vitamin B 12 1000 mcg intramuscularly 1 to 3 weeks prior to first dose of Pemetrexed for Injection and every 9 weeks thereafter, and dexamethasone 4 mg orally, twice daily, for 3 days starting the day prior to each Pemetrexed for Injection dose. Randomization was stratified by multiple baseline variables including KPS, histologic subtype (epithelial, mixed, sarcomatoid, other), and gender. The major efficacy outcome measure was overall survival and additional efficacy outcome measures were time to disease progression, overall response rate, and response duration. A total of 448 patients received at least one dose of protocol-specified therapy; 226 patients were randomized to and received at least one dose of Pemetrexed for Injection plus cisplatin, and 222 patients were randomized to and received cisplatin. Among the 226 patients who received cisplatin with Pemetrexed for Injection, 74% received full supplementation with folic acid and vitamin B 12 during study therapy, 14% were never supplemented, and 12% were partially supplemented. Across the study population, the median age was 61 years (range: 20 to 86 years); 81% were male; 92% were White, 5% were Hispanic or Latino, 3.1% were Asian, and <1% were other ethnicities; and 54% had a baseline KPS score of 90-100% and 46% had a KPS score of 70-80%. With regard to tumor characteristics, 46% had Stage IV disease, 31% Stage III, 15% Stage II, and 7% Stage I disease at baseline; the histologic subtype of mesothelioma was epithelial in 68% of patients, mixed in 16%, sarcomatoid in 10% and other histologic subtypes in 6%. The baseline demographics and tumor characteristics of the subgroup of fully supplemented patients was similar to the overall study population. The efficacy results from Study JMCH are summarized in Table 18 and Figure 9 .

Figure 9: Kaplan-Meier Curves for Overall Survival in Study JMCH Based upon prospectively defined criteria (modified Southwest Oncology Group methodology) the objective tumor response rate for Pemetrexed for Injection plus cisplatin was greater than the objective tumor response rate for cisplatin alone. There was also improvement in lung function (forced vital capacity) in the Pemetrexed for Injection plus cisplatin arm compared to the control arm. Figure 9

    Geriatric Use

    8.5 Geriatric Use Of the 3,946 patients enrolled in clinical studies of Pemetrexed for Injection, 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) ].

    Pediatric Use

    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 B 12 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.

    Pregnancy

    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).

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 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 for 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 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) ] . 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 B 12 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 for Injection, 34% were 65 and over and 4% were 75 and over.

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 for Injection is primarily excreted by the kidneys. Decreased renal function results in reduced clearance and greater exposure (AUC) to Pemetrexed for Injection 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) ].
