Alogliptin

1 INDICATIONS AND USAGE Alogliptin tablets are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus [see Clinical Studies (14) ]. Alogliptin tablets are a dipeptidyl peptidase-4 (DPP-4) inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. ( 1 ) Limitations of Use: Should not be used in patients with type 1 diabetes. ( 1 ) Limitations of Use Alogliptin tablets should not be used in patients with type 1 diabetes mellitus.

2 DOSAGE AND ADMINISTRATION The recommended dose in patients with normal renal function or mild renal impairment is 25 mg once daily. ( 2.1 ) Can be taken with or without food. ( 2.1 ) Adjust dose if moderate or severe renal impairment or end-stage renal disease (ESRD). ( 2.2 ) Degree of Renal Impairment Creatinine Clearance (mL/min) Recommended Dosing Moderate ≥30 to <60 12.5 mg once daily Severe/ESRD <30 6.25 mg once daily 2.1 Recommended Dosing The recommended dose of alogliptin tablets is 25 mg once daily. Alogliptin tablets may be taken with or without food. Do not split tablets. 2.2 Patients with Renal Impairment No dose adjustment of alogliptin tablets is necessary for patients with mild renal impairment (creatinine clearance [CrCl] ≥60 mL/min). The dose of alogliptin tablets is 12.5 mg once daily for patients with moderate renal impairment (CrCl ≥30 to <60 mL/min). The dose of alogliptin tablets is 6.25 mg once daily for patients with severe renal impairment (CrCl ≥15 to <30 mL/min) or with end-stage renal disease (ESRD) (CrCl <15 mL/min or requiring hemodialysis). Alogliptin tablets may be administered without regard to the timing of dialysis. Alogliptin tablets have not been studied in patients undergoing peritoneal dialysis [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ]. Because there is a need for dose adjustment based upon renal function, assessment of renal function is recommended prior to initiation of alogliptin tablets therapy and periodically thereafter.

A total of 14,778 patients with type 2 diabetes participated in 14 randomized, double-blind, controlled clinical trials of whom 9052 subjects were treated with alogliptin tablets, 3469 subjects were treated with placebo and 2257 were treated with an active comparator. The mean duration of diabetes was seven years, the mean body mass index (BMI) was 31 kg/m 2 (49% of patients had a BMI ≥30 kg/m 2 ), and the mean age was 58 years (26% of patients ≥65 years of age). The mean exposure to alogliptin tablets was 49 weeks with 3348 subjects treated for more than one year. In a pooled analysis of these 14 controlled clinical trials, the overall incidence of adverse reactions was 73% in patients treated with alogliptin tablets 25 mg compared to 75% with placebo and 70% with active comparator. Overall discontinuation of therapy due to adverse reactions was 6.8% with alogliptin tablets 25 mg compared to 8.4% with placebo or 6.2% with active comparator. Adverse reactions reported in ≥4% of patients treated with alogliptin tablets 25 mg and more frequently than in patients who received placebo are summarized in Table 1 . Table 1.

In the monotherapy study, the incidence of hypoglycemia was 1.5% in patients treated with alogliptin tablets compared to 1.6% with placebo. The use of alogliptin tablets as add-on therapy to glyburide or insulin did not increase the incidence of hypoglycemia compared to placebo. In a monotherapy study comparing alogliptin tablets to a sulfonylurea in elderly patients, the incidence of hypoglycemia was 5.4% with alogliptin tablets compared to 26% with glipizide (Table 2) . Table 2. Incidence and Rate of Hypoglycemia Adverse reactions of hypoglycemia were based on all reports of symptomatic and asymptomatic hypoglycemia; a concurrent glucose measurement was not required; intent-to-treat population. in Placebo and Active-Controlled Studies when Alogliptin Tablets Were Used as Add-On Therapy to Glyburide, Insulin, Metformin, Pioglitazone or Compared to Glipizide or Metformin Add-On to Glyburide (26 Weeks) Alogliptin Tablets 25 mg Placebo N=198 N=99 Overall (%) 19 (9.6) 11 (11.1) Severe (%) Severe events of hypoglycemia were defined as those events requiring medical assistance or exhibiting depressed level or loss of consciousness or seizure. 0 1 (1) Add-On to Insulin (± Metformin) (26 Weeks) Alogliptin Tablets 25 mg Placebo N=129 N=129 Overall (%) 35 (27) 31 (24) Severe (%) 1 (0.8) 2 (1.6) Add-On to Metformin (26 Weeks) Alogliptin Tablets 25 mg Placebo N=207 N=104 Overall (%) 0 3 (2.9) Severe (%) 0 0 Add-On to Pioglitazone (± Metformin or Sulfonylurea) (26 Weeks) Alogliptin Tablets 25 mg Placebo N=199 N=97 Overall (%) 14 (7.0) 5 (5.2) Severe (%) 0 1 (1) Compared to Glipizide (52 Weeks) Alogliptin Tablets 25 mg Glipizide N=222 N=219 Overall (%) 12 (5.4) 57 (26) Severe (%) 0 3 (1.4) Compared to Metformin (26 Weeks) Alogliptin Tablets 25 mg Metformin 500 mg twice daily N=112 N=109 Overall (%) 2 (1.8) 2 (1.8) Severe (%) 0 0 Add-On to Metformin Compared to Glipizide (52 Weeks) Alogliptin Tablets 25 mg Glipizide N=877 N=869 Overall (%) 12 (1.4) 207 (23.8) Severe (%) 0 4 (0.5) In the EXAMINE trial, the incidence of investigator reported hypoglycemia was 6.7% in patients receiving alogliptin tablets and 6.5% in patients receiving placebo. Serious adverse reactions of hypoglycemia were reported in 0.8% of patients treated with alogliptin tablets and in 0.6% of patients treated with placebo. Renal Impairment In glycemic control trials in patients with type 2 diabetes, 3.4% of patients treated with alogliptin tablets and 1.3% of patients treated with placebo had renal function adverse reactions. The most commonly reported adverse reactions were renal impairment (0.5% for alogliptin tablets and 0.1% for active comparators or placebo), decreased creatinine clearance (1.6% for alogliptin tablets and 0.5% for active comparators or placebo) and increased blood creatinine (0.5% for alogliptin tablets and 0.3% for active comparators or placebo) [see Use in Specific Populations (8.6) ] . In the EXAMINE trial of high CV risk type 2 diabetes patients, 23% of patients treated with alogliptin tablets and 21% of patients treated with placebo had an investigator reported renal impairment adverse reaction. The most commonly reported adverse reactions were renal impairment (7.7% for alogliptin tablets and 6.7% for placebo), decreased glomerular filtration rate (4.9% for alogliptin tablets and 4.3% for placebo) and decreased renal clearance (2.2% for alogliptin tablets and 1.8% for placebo). Laboratory measures of renal function were also assessed. Estimated glomerular filtration rate decreased by 25% or more in 21.1% of patients treated with alogliptin tablets and 18.7% of patients treated with placebo. Worsening of chronic kidney disease stage was seen in 16.8% of patients treated with alogliptin tablets and in 15.5% of patients treated with placebo. 6.2 Postmarketing Experience The following adverse reactions have been identified during the postmarketing use of alogliptin tablets. 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. Gastrointestinal disorders: acute pancreatitis, diarrhea, constipation, nausea, ileus Hepatobiliary disorders: fulminant hepatic failure Immune system disorders: hypersensitivity reactions including anaphylaxis Investigations: hepatic enzyme elevations Musculoskeletal and Connective Tissue Disorders: severe and disabling arthralgia, rhabdomyolysis Renal and urinary disorders: tubulointerstitial nephritis Skin and subcutaneous tissue disorders: angioedema, rash, urticaria and severe cutaneous adverse reactions including Stevens-Johnson syndrome, bullous pemphigoid
