ALIMTA

AbsorptionThe pharmacokinetics of pemetrexed when ALIMTA 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.

14.1 Non-Squamous NSCLC Initial Treatment in Combination with Pembrolizumab and Platinum The efficacy of ALIMTA 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...

The following adverse reactions are discussed in greater detail in other sections of the labeling: Myelosuppression [see Warnings and Precautions ( 5.1 )] Renal failure [see Warnings and Precautions ( 5.2 )] Bullous and exfoliative skin toxicity [see Warning and Precautions ( 5.3 )] Interstitial pneumonitis [see Warnings and Precautions ( 5.4 )] Radiation recall [see Warnings and Precautions ( 5.5 )] The most common adverse reactions (incidence ≥20%) of ALIMTA, when administered as a single agen...

ALIMTA 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 )

Myelosuppression: Can cause severe bone marrow suppression resulting in cytopenia and an increased risk of infection. Do not administer ALIMTA 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 ALIMTA. ( 2.4 , 5.1 ) Renal Failure: Can cause severe, and sometimes fatal, renal failure. Do no...

7 DRUG INTERACTIONS Ibuprofen increased risk of ALIMTA 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 creatinin...
