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, 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 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 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%).

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 for injection 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 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/cisplatin fully supplemented group and 2 in the pemetrexed/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 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, as compared to the control arm, for any specified adverse reaction listed in the table below.

Additional Experience Across Clinical Trials Sepsis, with or without neutropenia, including fatal cases : 1% Severe esophagitis, resulting in hospitalization: <1% 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of pemetrexed for injection. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Blood and Lymphatic System — immune-mediated hemolytic anemia Gastrointestinal — colitis, pancreatitis General Disorders and Administration Site Conditions — edema Injury, poisoning, and procedural complications — radiation recall Respiratory — interstitial pneumonitis Skin — Serious and fatal bullous skin conditions, Stevens-Johnson syndrome, and toxic epidermal necrolysis

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.
