( 6.1 ) The most common adverse reactions (incidence ≥20%) of pemetrexed when administered with cisplatin are vomiting, neutropenia, anemia, stomatitis/pharyngitis, thrombocytopenia, and constipation. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc., at 1-800-438-1985 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 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. Non-Squamous NSCLC Initial Treatment in Combination with Cisplatin The safety of pemetrexed was evaluated in Study JMDB, a randomized (1:1), open-label, multicenter trial conducted in chemotherapy-naive patients with locally advanced or metastatic NSCLC. 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 2 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 2.

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. Table 3 provides the frequency and severity of adverse reactions reported in ≥5% of the 438 pemetrexed-treated patients in Study JMEN.

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. Table 4 provides the frequency and severity of adverse reactions reported in ≥5% of the 333 pemetrexed-treated patients in PARAMOUNT.

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 5 provides the frequency and severity of adverse reactions reported in ≥5% of the 265 pemetrexed-treated patients in Study JMEI. Study JMEI is 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 the Table 5 below.

Incidence 1% to <5% Body as a Whole — abdominal pain, allergic reaction/hypersensitivity, febrile neutropenia, infection Dermatology/Skin — erythema multiforme Neurology — motor neuropathy, sensory neuropathy Incidence <1% Cardiovascular — supraventricular arrhythmias Renal — renal failure Mesothelioma The safety of pemetrexed was evaluated in Study JMCH, a randomized (1:1), single-blind study conducted in patients with MPM who had received no prior chemotherapy for MPM. 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 6 provides the frequency and severity of adverse reactions ≥5% in the subgroup of pemetrexed-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, as compared to the control arm, for any specified adverse reaction listed in the table below. Table 6: Adverse Reactions Occurring in ≥5% of Fully Supplemented Subgroup of Patients Receiving Pemetrexed/Cisplatin in Study JMCH In Study JMCH, 226 patients received at least one dose of pemetrexed in combination with cisplatin and 222 patients received at least one dose of cisplatin. Table 6 provides the ADRs for subgroup of patients treated with pemetrexed in combination with cisplatin (168 patients) or cisplatin alone (163 patients) who received full supplementation with folic acid and vitamin B 12 during study therapy.

( 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 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.

Clinical Pharmacology

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Pemetrexed 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 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.

PATIENT INFORMATION Pemetrexed (peh-meh-TREX-ed) Injection for intravenous use
This Patient Information has been approved by the U.S. Food and Drug Administration.Issued: 6/2022
What is Pemetrexed Injection?
Pemetrexed Injection is a prescription medicine used to treat:
  • a kind of lung cancer called non-squamous non-small cell lung cancer (NSCLC). Pemetrexed Injection is used:
  • as the first treatment in combination with cisplatin when your lung cancer has spread (advanced NSCLC).
  • alone as maintenance treatment after you have received 4 cycles of chemotherapy that contains platinum for first treatment of your advanced NSCLC and your cancer has not progressed.
  • alone when your lung cancer has returned or spread after prior chemotherapy.
  • Pemetrexed Injection is not for use for the treatment of people with squamous cell, non-small cell lung cancer.
  • a kind of cancer called malignant pleural mesothelioma. This cancer affects the lining of the lungs and chest wall. Pemetrexed Injection is used in combination with cisplatin as the first treatment for malignant pleural mesothelioma that cannot be removed by surgery or you are not able to have surgery.
  • Pemetrexed Injection has not been shown to be safe and effective in children.
    Do not take Pemetrexed Injection if you have had a severe allergic reaction to any medicine that contains pemetrexed.
    Before taking Pemetrexed Injection, tell your healthcare provider about all of your medical conditions, including if you:
  • have kidney problems.
  • have had radiation therapy.
  • are pregnant or plan to become pregnant. Pemetrexed Injection can harm your unborn baby. Females who are able to become pregnant: Your healthcare provider will check to see if you are pregnant before you start treatment with Pemetrexed Injection. You should use effective birth control (contraception) during treatment with Pemetrexed Injection and for 6 months after the last dose. Tell your healthcare provider right away if you become pregnant or think you are pregnant during treatment with Pemetrexed Injection. Males with female partners who are able to become pregnant should use effective birth control (contraception) during treatment with Pemetrexed Injection and for 3 months after the last dose.
  • are breastfeeding or plan to breastfeed. It is not known if Pemetrexed Injection passes into breast milk. Do not breastfeed during treatment with Pemetrexed Injection and for 1 week after the last dose.
  • Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Tell your healthcare provider if you have kidney problems and take a medicine that contains ibuprofen. You should avoid taking ibuprofen for 2 days before, the day of, and 2 days after receiving treatment with Pemetrexed Injection.
    How is Pemetrexed Injection given?
  • It is very important to take folic acid and vitamin B12 during your treatment with Pemetrexed Injection to lower your risk of harmful side effects.
  • Take folic acid exactly as prescribed by your healthcare provider 1 time a day, beginning 7 days (1 week) before your first dose of Pemetrexed Injection and continue taking folic acid until 21 days (3 weeks) after your last dose of Pemetrexed Injection.
  • Your healthcare provider will give you vitamin B12 injections during treatment with Pemetrexed Injection. You will get your first vitamin B12 injection 7 days (1 week) before your first dose of Pemetrexed Injection, and then every 3 cycles.
  • Your healthcare provider will prescribe a medicine called corticosteroid for you to take 2 times a day for 3 days, beginning the day before each treatment with Pemetrexed Injection.
  • Pemetrexed Injection is given to you by intravenous (IV) infusion into your vein. The infusion is given over 10 minutes.
  • Pemetrexed Injection is usually given once every 21 days (3 weeks).
  • What are the possible side effects of Pemetrexed Injection?
    Pemetrexed Injection can cause serious side effects, including:
  • Low blood cell counts. Low blood cell counts can be severe, including low white blood cell counts (neutropenia), low platelet counts (thrombocytopenia), and low red blood cell counts (anemia). Your healthcare provider will do blood tests to check your blood cell counts regularly during your treatment with Pemetrexed Injection. Tell your healthcare provider right away if you have any signs of infection, fever, bleeding, or severe tiredness during your treatment with Pemetrexed Injection.
  • Kidney problems, including kidney failure. Pemetrexed Injection can cause severe kidney problems that can lead to death. Severe vomiting or diarrhea can lead to loss of fluids (dehydration) which may cause kidney problems to become worse. Tell your healthcare provider right away if you have a decrease in the amount of urine you make.
  • Severe skin reactions. Severe skin reactions that may lead to death can happen with Pemetrexed Injection. Tell your healthcare provider right away if you develop blisters, skin sores, skin peeling, or painful sores, or ulcers in your mouth, nose, throat or genital area.
  • Lung problems (pneumonitis). Pemetrexed Injection can cause serious lung problems that can lead to death. Tell your healthcare provider right away if you get any new or worsening symptoms of shortness of breath, cough, or fever.
  • Radiation recall. Radiation recall is a skin reaction that can happen in people who have received radiation treatment in the past and are treated with Pemetrexed Injection. Tell your healthcare provider if you get swelling, blistering, or a rash that looks like a sunburn in an area that was previously treated with radiation.
  • The most common side effects of Pemetrexed Injection when given alone are:
  • tiredness
  • nausea
  • loss of appetite
  • The most common side effects of Pemetrexed Injection when given with cisplatin are:
  • vomiting
  • swelling or sores in your mouth or sore throat
  • constipation
  • low white blood cell counts (neutropenia)
  • low platelet counts (thrombocytopenia)
  • low red blood cell counts (anemia)
  • Pemetrexed Injection may cause fertility problems in males. This may affect your ability to father a child. It is not known if these effects are reversible. Talk to your healthcare provider if this is a concern for you. Your healthcare provider will do blood tests to check for side effects during treatment with Pemetrexed Injection. Your healthcare provider may change your dose of Pemetrexed Injection, delay treatment, or stop treatment if you have certain side effects. Tell your healthcare provider if you have any side effect that bothers you or that does not go away. These are not all of the possible side effects of Pemetrexed Injection.

    Clinical Studies

    14 CLINICAL STUDIES 14.1 Non-Squamous NSCLC Initial Treatment in Combination with Cisplatin The efficacy of pemetrexed 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 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 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 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 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 8 and Figure 1.

Patients were randomized to receive pemetrexed 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 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 10 and Figure 4.

Patients were required to have an ECOG PS of 0 or 1. Patients were randomized to receive pemetrexed 500 mg/m 2 intravenously every 21 days or placebo until disease progression. Randomization was stratified by response to pemetrexed 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 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. Efficacy results for PARAMOUNT are presented in Table 12 and Figure 7.

Patients were randomized to receive pemetrexed 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 also received folic acid and vitamin B 12 . The study was designed to show that overall survival with pemetrexed was non-inferior to docetaxel, as the major efficacy outcome measure, and that overall survival was superior for patients randomized to pemetrexed compared to docetaxel, as a secondary outcome measure. A total of 571 patients were enrolled with 283 patients randomized to pemetrexed 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 13 and 14, 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 in Studies JMDB and JMEN [see Clinical Studies (14.1) ] .

Patients were randomized (n=456) to receive pemetrexed 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 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 and every 9 weeks thereafter, and dexamethasone 4 mg orally, twice daily, for 3 days starting the day prior to each pemetrexed 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 plus cisplatin, and 222 patients were randomized to and received cisplatin. Among the 226 patients who received cisplatin with pemetrexed, 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 15 and Figure 8.

Figure 8: 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 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 plus cisplatin arm compared to the control arm. Figure 8

    Geriatric Use

    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) ] .

    Pediatric Use

    8.4 Pediatric Use The safety and effectiveness of Pemetrexed Injection in pediatric patients have not been established. The safety and pharmacokinetics of pemetrexed 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. Pharmacokinetics of pemetrexed 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 Injection can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on Pemetrexed 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 Injection, advise women not to breastfeed during treatment with Pemetrexed Injection and for one week after last dose. 8.3 Females and Males of Reproductive Potential Based on animal data, pemetrexed 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 Injection and for 6 months after the last dose of Pemetrexed Injection. Males Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use effective contraception during treatment with Pemetrexed Injection and for 3 months after the last dose [see Nonclinical Toxicology (13.1) ] . Infertility Males Pemetrexed 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 Injection in pediatric patients have not been established. The safety and pharmacokinetics of pemetrexed were evaluated in two clinical studies conducted in pediatric patients with recurrent solid tumors (NCT00070473, N=32 and NCT00520936, N=72).

[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) ] .
