The safety evaluation of TRADJENTA 5 mg once daily in patients with type 2 diabetes mellitus is based on 14 placebo-controlled trials, 1 active-controlled trial, and one trial in patients with severe renal impairment. In the 14 placebo-controlled studies, a total of 3,625 patients were randomized and treated with TRADJENTA 5 mg daily and 2,176 with placebo. The mean exposure in patients treated with TRADJENTA across studies was 29.6 weeks. The maximum follow-up was 78 weeks. TRADJENTA 5 mg once daily was studied as monotherapy in three placebo-controlled trials of 18 and 24 weeks' duration and in five additional placebo-controlled studies lasting ≤18 weeks. The use of TRADJENTA in combination with other antihyperglycemic agents was studied in six placebo-controlled trials: two with metformin (12 and 24 weeks' treatment duration); one with a sulfonylurea (18 weeks' treatment duration); one with metformin and sulfonylurea (24 weeks' treatment duration); one with pioglitazone (24 weeks' treatment duration); and one with insulin (primary endpoint at 24 weeks). In a pooled dataset of 14 placebo-controlled clinical trials, adverse reactions that occurred in ≥2% of patients receiving TRADJENTA (n = 3,625) and more commonly than in patients given placebo (n = 2,176), are shown in Table 1. Table 1 Adverse Reactions Reported in ≥2% of Patients Treated with TRADJENTA and Greater than Placebo in Placebo-Controlled Clinical Studies of TRADJENTA Monotherapy or Combination Therapy Adverse Reactions TRADJENTA 5 mg (%) n = 3,625 Placebo (%) n = 2,176 Nasopharyngitis 7.0 6.1 Diarrhea 3.3 3.0 Cough 2.1 1.4 Rates for other adverse reactions for TRADJENTA 5 mg vs placebo when TRADJENTA was used in combination with specific antidiabetic agents were: urinary tract infection (3.1% vs 0%) and hypertriglyceridemia (2.4% vs 0%) when TRADJENTA was used as add-on to sulfonylurea; hyperlipidemia (2.7% vs 0.8%) and weight increased (2.3% vs 0.8%) when TRADJENTA was used as add-on to pioglitazone; and constipation (2.1% vs 1%) when TRADJENTA was used as add-on to basal insulin therapy. Other adverse reactions reported in clinical studies with treatment of TRADJENTA were hypersensitivity (e.g., urticaria, angioedema, localized skin exfoliation, or bronchial hyperreactivity) and myalgia. Following 104 weeks' treatment in a controlled trial comparing TRADJENTA with glimepiride in which all patients were also receiving metformin, adverse reactions reported in ≥5% of patients treated with TRADJENTA (n = 776) and more frequently than in patients treated with a sulfonylurea (n = 775) were back pain (9.1% vs 8.4%), arthralgia (8.1% vs 6.1%), upper respiratory tract infection (8.0% vs 7.6%), headache (6.4% vs 5.2%), cough (6.1% vs 4.9%), and pain in extremity (5.3% vs 3.9%). In the clinical trial program, pancreatitis was reported in 15.2 cases per 10,000 patient year exposure while being t …

7 DRUG INTERACTIONS Strong P-glycoprotein/CYP3A4 inducer: The efficacy of TRADJENTA may be reduced when administered in combination (e.g., with rifampin). Use of alternative treatments is strongly recommended. ( 7.1 ) 7.1 Inducers of P-glycoprotein or CYP3A4 Enzymes Rifampin decreased linagliptin exposure, suggesting that the efficacy of TRADJENTA may be reduced when administered in combination with a strong P-gp or CYP3A4 inducer. Therefore, use of alternative treatments is strongly recommended when linagliptin is to be administered with a strong P-gp or CYP3A4 inducer [see Clinical Pharmacology (12.3) ] . 7.2 Insulin Secretagogues or Insulin Insulin and insulin secretagogues are known to cause hypoglycemia. The risk of hypoglycemia is increased when linagliptin is used in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin. Coadministration of TRADJENTA with an insulin secretagogue (e.g., sulfonylurea) or insulin may require lower dosages of the insulin secretagogue or insulin to reduce the risk of hypoglycemia [see Warnings and Precautions (5.2) ] .

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary The limited data with TRADJENTA use in pregnant women are not sufficient to inform of drug-associated risk for major birth defects and miscarriage. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations ]. In animal reproduction studies, no adverse developmental effects were observed when linagliptin was administered to pregnant rats during the period of organogenesis at doses similar to the maximum recommended clinical dose, based on exposure [see Data ] . The estimated background risk of major birth defects is 6% to 10% in women with pre-gestational diabetes with a HbA1c >7 and has been reported to be as high as 20% to 25% in women with HbA1c >10. The estimated background risk of miscarriage for the indicated population is unknown. 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. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity. Data Animal Data No adverse developmental outcome was observed when linagliptin was administered to pregnant Wistar Han rats and Himalayan rabbits during the period of organogenesis at doses up to 240 mg/kg/day and 150 mg/kg/day, respectively. These doses represent approximately 943-times (rats) and 1,943-times (rabbits) the 5 mg maximum clinical dose, based on exposure. No adverse functional, behavioral, or reproductive outcome was observed in offspring following administration of linagliptin to Wistar Han rats from gestation day 6 to lactation day 21 at a dose 49-times the maximum recommended human dose, based on exposure. Linagliptin crosses the placenta into the fetus following oral dosing in pregnant rats and rabbits. 8.2 Lactation Risk Summary There is no information regarding the presence of linagliptin in human milk, the effects on the breastfed infant, or the effects on milk production. However, linagliptin is present in rat milk. Therefore, the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for TRADJENTA and any potential adverse effects on the breastfed child from TRADJENTA or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of TRADJENTA have not been established in pediatric patients. Effectiveness of TRADJENTA was not demonstrated in a 26-week randomized, double-blind, placebo-controlled trial (NCT03429543) in 157 pediatric patients aged 10 to 17 years with inadequately controlled type 2 diabetes mellitus. 8.5 Geriatric Use In linagliptin studies, 1,085 linagliptin-treated patients were 65 years of age and older and 131 patients were 75 years of age and older. In these linagliptin studies, no overall differences in safety or effectiveness of linagliptin were observed between geriatric patients and younger adult patients. 8.6 Renal Impairment No dosage adjustment is recommended for patients with renal impairment [see Clinical Pharmacology (12.3) ]. In the TRADJENTA treatment arm of the CARMELINA trial [see Clinical Studies (14) ] , 2,200 (63%) patients had renal impairment (eGFR <60 mL/min/1.73 m 2 ). Approximately 20% of the population had eGFR ≥45 to <60 mL/min/1.73 m 2 , 28% of the population had eGFR ≥30 to <45 mL/min/1.73 m 2 and 15% had eGFR <30 mL/min/1.73 m 2 . The overall incidence of adverse reactions were generally similar between the TRADJENTA and placebo treatment arms. 8.7 Hepatic Impairment No dose adjustment is recommended for patients with hepatic impairment [see Clinical Pharmacology (12.3) ] .

12.1 Mechanism of Action Linagliptin is an inhibitor of DPP-4, an enzyme that degrades the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Thus, linagliptin increases the concentrations of active incretin hormones, stimulating the release of insulin in a glucose-dependent manner and decreasing the levels of glucagon in the circulation. Both incretin hormones are involved in the physiological regulation of glucose homeostasis. Incretin hormones are secreted at a low basal level throughout the day and levels rise immediately after meal intake. GLP-1 and GIP increase insulin biosynthesis and secretion from pancreatic beta cells in the presence of normal and elevated blood glucose levels. Furthermore, GLP-1 also reduces glucagon secretion from pancreatic alpha-cells, resulting in a reduction in hepatic glucose output.
