DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. Alogliptin tablets are primarily renally excreted. Cytochrome (CYP) P450-related metabolism is negligible. No significant drug-drug interactions were observed with the CYP-substrates or inhibitors tested or with renally excreted drugs [see Clinical Pharmacology (12.3)].

GERIATRIC USE SECTION.

8.5 Geriatric Use. Of the total number of patients (N=9052) in clinical safety and efficacy studies treated with alogliptin tablets, 2257 (24.9%) patients were 65 years and older and 386 (4.3%) patients were 75 years and older. No overall differences in safety or effectiveness were observed between patients 65 years and over and younger patients. While this clinical experience has not identified differences in responses between the elderly and younger patients, greater sensitivity of some older individuals cannot be ruled out.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.A total of 14,778 patients with type 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/m2 (49% of patients had BMI >=30 kg/m2), 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 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.

HypoglycemiaHypoglycemic events were documented based upon blood glucose value and/or clinical signs and symptoms of hypoglycemia.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 monotherapy study comparing alogliptin tablets to 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 HypoglycemiaAdverse reactions of hypoglycemia were based on all reports of symptomatic and asymptomatic hypoglycemia; 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 MetforminAdd-On to Glyburide(26 Weeks)Alogliptin Tablets 25 mgPlaceboN=198N=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. 01 (1)Add-On to Insulin (+- Metformin)(26 Weeks)Alogliptin Tablets 25 mgPlaceboN=129N=129 Overall (%)35 (27)31 (24) Severe (%) (0.8)2 (1.6)Add-On to Metformin(26 Weeks)Alogliptin Tablets 25 mgPlaceboN=207N=104 Overall (%)03 (2.9) Severe (%) 00Add-On to Pioglitazone(+- Metformin or Sulfonylurea)(26 Weeks)Alogliptin Tablets 25 mgPlaceboN=199N=97 Overall (%)14 (7.0)5 (5.2) Severe (%) 01 (1)Compared to Glipizide(52 Weeks)Alogliptin Tablets 25 mgGlipizideN=222N=219 Overall (%)12 (5.4)57 (26) Severe (%) 03 (1.4)Compared to Metformin(26 Weeks)Alogliptin Tablets 25 mgMetformin 500 mgtwice dailyN=112N=109 Overall (%)2 (1.8)2 (1.8) Severe (%) 00Add-On to Metformin Compared to Glipizide(52 Weeks)Alogliptin Tablets 25 mgGlipizideN=877N=869 Overall (%)12 (1.4)207 (23.8) Severe (%) 04 (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 ImpairmentIn glycemic control trials in patients with type 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 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. 6.2Postmarketing Experience. The following adverse reactions have been identified during the postmarketing use of alogliptin tablets. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.Acute Pancreatitis, hypersensitivity reactions including anaphylaxis, angioedema, rash, urticaria and severe cutaneous adverse reactions, including Stevens-Johnson syndrome, hepatic enzyme elevations, fulminant hepatic failure, severe and disabling arthralgia, bullous pemphigoid, rhabdomyolysis, and diarrhea, constipation, nausea, and ileus [see Warnings and Precautions (5.1, 5.3, 5.4, 5.6, 5.7)].

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Rats were administered oral doses of 75, 400 and 800 mg/kg alogliptin for two years. No drug-related tumors were observed up to 75 mg/kg or approximately 32 times the maximum recommended clinical dose of 25 mg, based on area under the plasma concentration curve (AUC) exposure. At higher doses (approximately 308 times the maximum recommended clinical dose of 25 mg), combination of thyroid C-cell adenomas and carcinomas increased in male but not female rats. No drug-related tumors were observed in mice after administration of 50, 150 or 300 mg/kg alogliptin for two years, or up to approximately 51 times the maximum recommended clinical dose of 25 mg, based on AUC exposure.Alogliptin was not mutagenic or clastogenic, with and without metabolic activation, in the Ames test with S. typhimurium and E. coli or the cytogenetic assay in mouse lymphoma cells. Alogliptin was negative in the in vivo mouse micronucleus study.In fertility study in rats, alogliptin had no adverse effects on early embryonic development, mating or fertility at doses up to 500 mg/kg, or approximately 172 times the clinical dose based on plasma drug exposure (AUC).

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Increased concentrations of the incretin hormones such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are released into the bloodstream from the small intestine in response to meals. These hormones cause insulin release from the pancreatic beta cells in glucose-dependent manner but are inactivated by the dipeptidyl peptidase-4 (DPP-4) enzyme within minutes. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, reducing hepatic glucose production. In patients with type diabetes, concentrations of GLP-1 are reduced but the insulin response to GLP-1 is preserved. Alogliptin is DPP-4 inhibitor that slows the inactivation of the incretin hormones, thereby increasing their bloodstream concentrations and reducing fasting and postprandial glucose concentrations in glucose-dependent manner in patients with type diabetes mellitus. Alogliptin selectively binds to and inhibits DPP-4 but not DPP-8 or DPP-9 activity in vitro at concentrations approximating therapeutic exposures.. 12.2 Pharmacodynamics. Single-dose administration of alogliptin tablets to healthy subjects resulted in peak inhibition of DPP-4 within two to three hours after dosing. The peak inhibition of DPP-4 exceeded 93% across doses of 12.5 mg to 800 mg. Inhibition of DPP-4 remained above 80% at 24 hours for doses greater than or equal to 25 mg. Peak and total exposure over 24 hours to active GLP-1 were three to four fold greater with alogliptin tablets (at doses of 25 to 200 mg) than placebo. In 16 week, double-blind, placebo-controlled study, alogliptin tablets 25 mg demonstrated decreases in postprandial glucagon while increasing postprandial active GLP-1 levels compared to placebo over an eight hour period following standardized meal. It is unclear how these findings relate to changes in overall glycemic control in patients with type diabetes mellitus. In this study, alogliptin tablets 25 mg demonstrated decreases in two hour postprandial glucose compared to placebo (-30 mg/dL versus 17 mg/dL, respectively).Multiple-dose administration of alogliptin to patients with type diabetes also resulted in peak inhibition of DPP-4 within one to two hours and exceeded 93% across all doses (25 mg, 100 mg and 400 mg) after single dose and after 14 days of once-daily dosing. At these doses of alogliptin tablets, inhibition of DPP-4 remained above 81% at 24 hours after 14 days of dosing.. Cardiac ElectrophysiologyIn randomized, placebo-controlled, four-arm, parallel-group study, 257 subjects were administered either alogliptin 50 mg, alogliptin 400 mg, moxifloxacin 400 mg or placebo once daily for total of seven days. No increase in corrected QT (QTc) was observed with either dose of alogliptin. At the 400 mg dose, peak alogliptin plasma concentrations were 19 fold higher than the peak concentrations following the maximum recommended clinical dose of 25 mg.. 12.3 Pharmacokinetics. The pharmacokinetics of alogliptin tablets has been studied in healthy subjects and in patients with type diabetes. After administration of single, oral doses up to 800 mg in healthy subjects, the peak plasma alogliptin concentration (median Tmax) occurred one to two hours after dosing. At the maximum recommended clinical dose of 25 mg, alogliptin tablets were eliminated with mean terminal half-life (T1/2) of approximately 21 hours.After multiple-dose administration up to 400 mg for 14 days in patients with type diabetes, accumulation of alogliptin was minimal with an increase in total [e.g., area under the plasma concentration curve (AUC)] and peak (i.e., Cmax) alogliptin exposures of 34% and 9%, respectively. Total and peak exposure to alogliptin increased proportionally across single doses and multiple doses of alogliptin ranging from 25 mg to 400 mg. The intersubject coefficient of variation for alogliptin AUC was 17%. The pharmacokinetics of alogliptin tablets were also shown to be similar in healthy subjects and in patients with type diabetes.. AbsorptionThe absolute bioavailability of alogliptin tablets is approximately 100%. Administration of alogliptin tablets with high-fat meal results in no significant change in total and peak exposure to alogliptin. Alogliptin tablets may therefore be administered with or without food.. DistributionFollowing single, 12.5 mg intravenous infusion of alogliptin to healthy subjects, the volume of distribution during the terminal phase was 417 L, indicating that the drug is well distributed into tissues.Alogliptin is 20% bound to plasma proteins.. MetabolismAlogliptin does not undergo extensive metabolism and 60% to 71% of the dose is excreted as unchanged drug in the urine.Two minor metabolites were detected following administration of an oral dose of [14C] alogliptin, N-demethylated, M-I (less than 1% of the parent compound), and N-acetylated alogliptin, M-II (less than 6% of the parent compound). M-I is an active metabolite and is an inhibitor of DPP-4 similar to the parent molecule; M-II does not display any inhibitory activity toward DPP-4 or other DPP-related enzymes. In vitro data indicate that CYP2D6 and CYP3A4 contribute to the limited metabolism of alogliptin.Alogliptin exists predominantly as the (R)-enantiomer (more than 99%) and undergoes little or no chiral conversion in vivo to the (S)-enantiomer. The (S)-enantiomer is not detectable at the 25 mg dose.. ExcretionThe primary route of elimination of [14C] alogliptin-derived radioactivity occurs via renal excretion (76%) with 13% recovered in the feces, achieving total recovery of 89% of the administered radioactive dose. The renal clearance of alogliptin (9.6 L/hr) indicates some active renal tubular secretion and systemic clearance was 14.0 L/hr.. Special Populations. Renal ImpairmentA single-dose, open-label study was conducted to evaluate the pharmacokinetics of alogliptin 50 mg in patients with chronic renal impairment compared with healthy subjects.In patients with mild renal impairment (creatinine clearance [CrCl] >=60 to <90 mL/min), an approximate 1.2 fold increase in plasma AUC of alogliptin was observed. Because increases of this magnitude are not considered clinically relevant, dose adjustment for patients with mild renal impairment is not recommended.In patients with moderate renal impairment (CrCl >=30 to <60 mL/min), an approximate two fold increase in plasma AUC of alogliptin was observed. To maintain similar systemic exposures of alogliptin tablets to those with normal renal function, the recommended dose is 12.5 mg once daily in patients with moderate renal impairment.In patients with severe renal impairment (CrCl >=15 to <30 mL/min) and end-stage renal disease (ESRD) (CrCl <15 mL/min or requiring dialysis), an approximate three and four fold increase in plasma AUC of alogliptin were observed, respectively. Dialysis removed approximately 7% of the drug during three hour dialysis session. Alogliptin tablets may be administered without regard to the timing of the dialysis. To maintain similar systemic exposures of alogliptin tablets to those with normal renal function, the recommended dose is 6.25 mg once daily in patients with severe renal impairment, as well as in patients with ESRD requiring dialysis.. Hepatic ImpairmentTotal exposure to alogliptin was approximately 10% lower and peak exposure was approximately 8% lower in patients with moderate hepatic impairment (Child-Pugh Grade B) compared to healthy subjects. The magnitude of these reductions is not considered to be clinically meaningful. Patients with severe hepatic impairment (Child-Pugh Grade C) have not been studied. Use caution when administering alogliptin tablets to patients with liver disease [see Use in Specific Populations (8.6) and Warnings and Precautions (5.3)].. GenderNo dose adjustment of alogliptin tablets is necessary based on gender. Gender did not have any clinically meaningful effect on the pharmacokinetics of alogliptin.. GeriatricNo dose adjustment of alogliptin tablets is necessary based on age. Age did not have any clinically meaningful effect on the pharmacokinetics of alogliptin.. PediatricStudies characterizing the pharmacokinetics of alogliptin in pediatric patients have not been performed.. RaceNo dose adjustment of alogliptin tablets is necessary based on race. Race (White, Black, and Asian) did not have any clinically meaningful effect on the pharmacokinetics of alogliptin.. Drug Interactions. In Vitro Assessment of Drug InteractionsIn vitro studies indicate that alogliptin is neither an inducer of CYP1A2, CYP2B6, CYP2C9, CYP2C19 and CYP3A4, nor an inhibitor of CYP1A2, CYP2C8, CYP2C9, CYP2C19, CYP3A4 and CYP2D6 at clinically relevant concentrations.. In Vivo Assessment of Drug Interactions. Effects of Alogliptin on the Pharmacokinetics of Other DrugsIn clinical studies, alogliptin did not meaningfully increase the systemic exposure to the following drugs that are metabolized by CYP isozymes or excreted unchanged in urine (Figure 1). No dose adjustment of alogliptin tablets is recommended based on results of the described pharmacokinetic studies.Figure 1. Effect of Alogliptin on the Pharmacokinetic Exposure to Other DrugsWarfarin was given once daily at stable dose in the range of mg to 10 mg. Alogliptin had no significant effect on the prothrombin time (PT) or International Normalized Ratio (INR).Caffeine (1A2 substrate), tolbutamide (2C9 substrate), dextromethorphan (2D6 substrate), midazolam (3A4 substrate) and fexofenadine (P-gp substrate) were administered as cocktail.. Figure 1. Effects of Other Drugs on the Pharmacokinetics of AlogliptinThere are no clinically meaningful changes in the pharmacokinetics of alogliptin when alogliptin tablets are administered concomitantly with the drugs described below (Figure 2).Figure 2. Effect of Other Drugs on the Pharmacokinetic Exposure of Alogliptin. Figure 2.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. Alogliptin tablets have been studied as monotherapy and in combination with metformin, sulfonylurea, thiazolidinedione (either alone or in combination with metformin or sulfonylurea) and insulin (either alone or in combination with metformin).A total of 14,053 patients with type diabetes were randomized in 11 double-blind, placebo- or active-controlled clinical safety and efficacy studies conducted to evaluate the effects of alogliptin tablets on glycemic control. The racial distribution of patients exposed to study medication was 70% Caucasian, 17% Asian, 6% Black and 7% other racial groups. The ethnic distribution was 30% Hispanic. Patients had an overall mean age of 57 years (range 21 to 91 years).In patients with type diabetes, treatment with alogliptin tablets produced clinically meaningful and statistically significant improvements in hemoglobin A1c (A1C) compared to placebo. As is typical for trials of agents to treat type diabetes, the mean reduction in A1C with alogliptin tablets appears to be related to the degree of A1C elevation at baseline.Alogliptin tablets had similar changes from baseline in serum lipids compared to placebo.. 14.1Patients with Inadequate Glycemic Control on Diet and Exercise. total of 1768 patients with type diabetes participated in three double-blind studies to evaluate the efficacy and safety of alogliptin tablets in patients with inadequate glycemic control on diet and exercise. All three studies had four week, single-blind, placebo run-in period followed by 26 week randomized treatment period. Patients who failed to meet prespecified hyperglycemic goals during the 26 week treatment periods received glycemic rescue therapy.In 26 week, double-blind, placebo-controlled study, total of 329 patients (mean baseline A1C 8%) were randomized to receive alogliptin tablets 12.5 mg, alogliptin tablets 25 mg or placebo once daily. Treatment with alogliptin tablets 25 mg resulted in statistically significant improvements from baseline in A1C and fasting plasma glucose (FPG) compared to placebo at Week 26 (Table 3). total of 8% of patients receiving alogliptin tablets 25 mg and 30% of those receiving placebo required glycemic rescue therapy.Improvements in A1C were not affected by gender, age or baseline body mass index (BMI).The mean change in body weight with alogliptin tablets was similar to placebo.Table 3.

Both coadministration treatment arms (alogliptin tablets 12.5 mg metformin HCl 500 mg and alogliptin tablets 12.5 mg metformin HCl 1000 mg) resulted in statistically significant improvements in A1C and FPG when compared with their respective individual alogliptin and metformin component regimens (Table 5). Coadministration treatment arms demonstrated improvements in two hour postprandial glucose (PPG) compared to alogliptin tablets alone or metformin alone (Table 5). total of 12.3% of patients receiving alogliptin tablets 12.5 mg metformin HCl 500 mg, 2.6% of patients receiving alogliptin tablets 12.5 mg metformin HCl 1000 mg, 17.3% of patients receiving alogliptin tablets 12.5 mg, 22.9% of patients receiving metformin HCl 500 mg, 10.8% of patients receiving metformin HCl 1000 mg and 38.7% of patients receiving placebo required glycemic rescue.Improvements in A1C were not affected by gender, age, race or baseline BMI. The mean decrease in body weight was similar between metformin alone and alogliptin tablets when coadministered with metformin.Table 5.

Add-On Therapy to MetforminA total of 2081 patients with type diabetes participated in two 26 week, double-blind, placebo-controlled studies to evaluate the efficacy and safety of alogliptin tablets as add-on therapy to metformin. In both studies, patients were inadequately controlled on metformin at dose of at least 1500 mg per day or at the maximum tolerated dose. All patients entered four week, single-blind placebo run-in period prior to randomization. Patients who failed to meet prespecified hyperglycemic goals during the 26 week treatment periods received glycemic rescue therapy.In the first 26 week, placebo-controlled study, total of 527 patients already on metformin (mean baseline A1C 8%) were randomized to receive alogliptin tablets 12.5 mg, alogliptin tablets 25 mg or placebo. Patients were maintained on stable dose of metformin (median dose 1700 mg) during the treatment period. Alogliptin tablets 25 mg in combination with metformin resulted in statistically significant improvements from baseline in A1C and FPG at Week 26, when compared to placebo (Table 6). total of 8% of patients receiving alogliptin tablets 25 mg and 24% of patients receiving placebo required glycemic rescue.Improvements in A1C were not affected by gender, age, baseline BMI or baseline metformin dose.The mean decrease in body weight was similar between alogliptin tablets and placebo when given in combination with metformin.Table 6.

Add-On Therapy to ThiazolidinedioneIn 26 week, placebo-controlled study, total of 493 patients inadequately controlled on thiazolidinedione alone or in combination with metformin or sulfonylurea (10 mg) (mean baseline A1C 8%) were randomized to receive alogliptin tablets 12.5 mg, alogliptin tablets 25 mg or placebo. Patients were maintained on stable dose of pioglitazone (median dose 30 mg) during the treatment period; those who were also previously treated on metformin (median dose 2000 mg) or sulfonylurea (median dose 10 mg) prior to randomization were maintained on the combination therapy during the treatment period. All patients entered into four week, single-blind placebo run-in period prior to randomization. Patients who failed to meet prespecified hyperglycemic goals during the 26 week treatment period received glycemic rescue therapy.The addition of alogliptin tablets 25 mg once daily to pioglitazone therapy resulted in statistically significant improvements from baseline in A1C and FPG at Week 26, compared to placebo (Table 8). total of 9% of patients who were receiving alogliptin tablets 25 mg and 12% of patients receiving placebo required glycemic rescue.Improvements in A1C were not affected by gender, age, baseline BMI or baseline pioglitazone dose.Clinically meaningful reductions in A1C were observed with alogliptin tablets compared to placebo regardless of whether subjects were receiving concomitant metformin or sulfonylurea (-0.2% placebo versus -0.9% alogliptin tablets) therapy or pioglitazone alone (0% placebo versus -0.52% alogliptin tablets).The mean increase in body weight was similar between alogliptin tablets and placebo when given in combination with pioglitazone.Table 8.

Add-on Combination Therapy with Pioglitazone and MetforminIn 52 week, active-comparator study, total of 803 patients inadequately controlled (mean baseline A1C 8.2%) on current regimen of pioglitazone 30 mg and metformin at least 1500 mg per day or at the maximum tolerated dose were randomized to either receive the addition of alogliptin tablets 25 mg or the titration of pioglitazone 30 mg to 45 mg following four week, single-blind placebo run-in period. Patients were maintained on stable dose of metformin (median dose 1700 mg). Patients who failed to meet prespecified hyperglycemic goals during the 52 week treatment period received glycemic rescue therapy.In combination with pioglitazone and metformin, alogliptin tablets 25 mg were shown to be statistically superior in lowering A1C and FPG compared with the titration of pioglitazone from 30 mg to 45 mg at Week 26 and at Week 52 (Table 9; results shown only for Week 52). total of 11% of patients in the alogliptin tablets 25 mg treatment group and 22% of patients in the pioglitazone up-titration group required glycemic rescue.Improvements in A1C were not affected by gender, age, race or baseline BMI.The mean increase in body weight was similar in both treatment arms.Table 9.

Add-On Therapy to SulfonylureaIn 26 week, placebo-controlled study, total of 500 patients inadequately controlled on sulfonylurea (mean baseline A1C 8.1%) were randomized to receive alogliptin tablets 12.5 mg, alogliptin tablets 25 mg or placebo. Patients were maintained on stable dose of glyburide (median dose 10 mg) during the treatment period. All patients entered into four week, single-blind, placebo run-in period prior to randomization. Patients who failed to meet prespecified hyperglycemic goals during the 26 week treatment period received glycemic rescue therapy.The addition of alogliptin tablets 25 mg to glyburide therapy resulted in statistically significant improvements from baseline in A1C at Week 26 when compared to placebo (Table 10). Improvements in FPG observed with alogliptin tablets 25 mg were not statistically significant compared with placebo. total of 16% of patients receiving alogliptin tablets 25 mg and 28% of those receiving placebo required glycemic rescue.Improvements in A1C were not affected by gender, age, baseline BMI or baseline glyburide dose.The mean change in body weight was similar between alogliptin tablets and placebo when given in combination with glyburide.Table 10.

Add-On Therapy to InsulinIn 26 week, placebo-controlled study, total of 390 patients inadequately controlled on insulin alone (42%) or in combination with metformin (58%) (mean baseline A1C 9.3%) were randomized to receive alogliptin tablets 12.5 mg, alogliptin tablets 25 mg or placebo. Patients were maintained on their insulin regimen (median dose 55 IU) upon randomization and those previously treated with insulin in combination with metformin (median dose 1700 mg) prior to randomization continued on the combination regimen during the treatment period. Patients entered the trial on short-, intermediate- or long-acting (basal) insulin or premixed insulin. Patients who failed to meet prespecified hyperglycemic goals during the 26 week treatment period received glycemic rescue therapy.The addition of alogliptin tablets 25 mg once daily to insulin therapy resulted in statistically significant improvements from baseline in A1C and FPG at Week 26, when compared to placebo (Table 11). total of 20% of patients receiving alogliptin tablets 25 mg and 40% of those receiving placebo required glycemic rescue.Improvements in A1C were not affected by gender, age, baseline BMI or baseline insulin dose. Clinically meaningful reductions in A1C were observed with alogliptin tablets compared to placebo regardless of whether subjects were receiving concomitant metformin and insulin (-0.2% placebo versus -0.8% alogliptin tablets) therapy or insulin alone (0.1% placebo versus -0.7% alogliptin tablets).The mean increase in body weight was similar between alogliptin tablets and placebo when given in combination with insulin.Table 11.

The trial compared the risk of major adverse cardiovascular events (MACE) between alogliptin tablets (N=2701) and placebo (N=2679) when added to standard of care therapies for diabetes and atherosclerotic vascular disease (ASCVD). The trial was event driven and patients were followed until sufficient number of primary outcome events accrued.Eligible patients were adults with type diabetes who had inadequate glycemic control at baseline (e.g., HbA1c >6.5%) and had been hospitalized for an acute coronary syndrome event (e.g., acute myocardial infarction or unstable angina requiring hospitalization) 15 to 90 days prior to randomization. The dose of alogliptin tablets was based on estimated renal function at baseline per dosage and administration recommendations [see Dosage and Administration (2.2)]. The average time between an acute coronary syndrome event and randomization was approximately 48 days.The mean age of the population was 61 years. Most patients were male (68%), Caucasian (73%), and were recruited from outside of the United States (86%). Asian and Black patients contributed 20% and 4% of the total population, respectively. At the time of randomization patients had diagnosis of type diabetes mellitus for approximately years, 87% had prior myocardial infarction and 14% were current smokers. Hypertension (83%) and renal impairment (27% with an eGFR <=60 ml/min/1.73 m2) were prevalent co-morbid conditions. Use of medications to treat diabetes (e.g., metformin 73%, sulfonylurea 54%, insulin 41%), and ASCVD (e.g., statin 94%, aspirin 93%, renin-angiotensin system blocker 88%, beta-blocker 87%) was similar between patients randomized to alogliptin tablets and placebo at baseline. During the trial, medications to treat diabetes and ASCVD could be adjusted to ensure care for these conditions adhered to standard of care recommendations set by local practice guidelines.The primary endpoint in EXAMINE was the time to first occurrence of MACE defined as the composite of cardiovascular death, nonfatal myocardial infarction (MI), or nonfatal stroke. The study was designed to exclude pre-specified risk margin of 1.3 for the hazard ratio of MACE. The median exposure to study drug was 526 days and 95% of the patients were followed to study completion or death.Table 12 shows the study results for the primary MACE composite endpoint and the contribution of each component to the primary MACE endpoint. The upper bound of the confidence interval was 1.16 and excluded risk margin larger than 1.3.Table 12.

INFORMATION FOR PATIENTS SECTION.

17 PATIENT COUNSELING INFORMATION. Advise the patient to read the FDA-approved patient labeling (Medication Guide).Inform patients of the potential risks and benefits of alogliptin tablets.Patients should be informed that acute pancreatitis has been reported during use of alogliptin tablets. Patients should be informed that persistent, severe abdominal pain, sometimes radiating to the back, which may or may not be accompanied by vomiting, is the hallmark symptom of acute pancreatitis. Patients should be instructed to promptly discontinue alogliptin tablets and contact their physician if persistent severe abdominal pain occurs. Patients should be informed of the signs and symptoms of heart failure. Before initiating alogliptin tablets, patients should be asked about history of heart failure or other risk factors for heart failure including moderate to severe renal impairment. Patients should be instructed to contact their healthcare providers as soon as possible if they experience symptoms of heart failure, including increasing shortness of breath, rapid increase in weight, or swelling of the feet.Patients should be informed that allergic reactions have been reported during use of alogliptin tablets. If symptoms of allergic reactions (including skin rash, hives and swelling of the face, lips, tongue and throat that may cause difficulty in breathing or swallowing) occur, patients should be instructed to discontinue alogliptin tablets and seek medical advice promptly.Patients should be informed that postmarketing reports of liver injury, sometimes fatal, have been reported during use of alogliptin tablets. If signs or symptoms of liver injury occur, patients should be instructed to discontinue alogliptin tablets and seek medical advice promptly.Inform patients that hypoglycemia can occur, particularly when an insulin secretagogue or insulin is used in combination with alogliptin tablets. Explain the risks, symptoms and appropriate management of hypoglycemia.Inform patients that severe and disabling joint pain may occur with this class of drugs. The time to onset of symptoms can range from one day to years.

LACTATION SECTION.

8.2 Lactation. Risk SummaryThere is no information regarding the presence of alogliptin in human milk, the effects on the breastfed infant, or the effects on milk production. Alogliptin is present in rat milk: however, due to species specific differences in lactation physiology, animal lactation data may not reliably predict levels in human milk. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for alogliptin tablets and any potential adverse effects on the breastfed infant from alogliptin tablets or from the underlying maternal condition.

MECHANISM OF ACTION SECTION.

12.1 Mechanism of Action. Increased concentrations of the incretin hormones such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are released into the bloodstream from the small intestine in response to meals. These hormones cause insulin release from the pancreatic beta cells in glucose-dependent manner but are inactivated by the dipeptidyl peptidase-4 (DPP-4) enzyme within minutes. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, reducing hepatic glucose production. In patients with type diabetes, concentrations of GLP-1 are reduced but the insulin response to GLP-1 is preserved. Alogliptin is DPP-4 inhibitor that slows the inactivation of the incretin hormones, thereby increasing their bloodstream concentrations and reducing fasting and postprandial glucose concentrations in glucose-dependent manner in patients with type diabetes mellitus. Alogliptin selectively binds to and inhibits DPP-4 but not DPP-8 or DPP-9 activity in vitro at concentrations approximating therapeutic exposures.

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Rats were administered oral doses of 75, 400 and 800 mg/kg alogliptin for two years. No drug-related tumors were observed up to 75 mg/kg or approximately 32 times the maximum recommended clinical dose of 25 mg, based on area under the plasma concentration curve (AUC) exposure. At higher doses (approximately 308 times the maximum recommended clinical dose of 25 mg), combination of thyroid C-cell adenomas and carcinomas increased in male but not female rats. No drug-related tumors were observed in mice after administration of 50, 150 or 300 mg/kg alogliptin for two years, or up to approximately 51 times the maximum recommended clinical dose of 25 mg, based on AUC exposure.Alogliptin was not mutagenic or clastogenic, with and without metabolic activation, in the Ames test with S. typhimurium and E. coli or the cytogenetic assay in mouse lymphoma cells. Alogliptin was negative in the in vivo mouse micronucleus study.In fertility study in rats, alogliptin had no adverse effects on early embryonic development, mating or fertility at doses up to 500 mg/kg, or approximately 172 times the clinical dose based on plasma drug exposure (AUC).

OVERDOSAGE SECTION.

10 OVERDOSAGE. The highest doses of alogliptin tablets administered in clinical trials were single doses of 800 mg to healthy subjects and doses of 400 mg once daily for 14 days to patients with type diabetes (equivalent to 32 times and 16 times the maximum recommended clinical dose of 25 mg, respectively). No serious adverse reactions were observed at these doses.In the event of an overdose, it is reasonable to institute the necessary clinical monitoring and supportive therapy as dictated by the patients clinical status. Per clinical judgment, it may be reasonable to initiate removal of unabsorbed material from the gastrointestinal tract.Alogliptin is minimally dialyzable; over three-hour hemodialysis session, approximately 7% of the drug was removed. Therefore, hemodialysis is unlikely to be beneficial in an overdose situation. It is not known if alogliptin tablets are dialyzable by peritoneal dialysis.

8.4 Pediatric Use. Safety and effectiveness of alogliptin tablets in pediatric patients have not been established.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. Single-dose administration of alogliptin tablets to healthy subjects resulted in peak inhibition of DPP-4 within two to three hours after dosing. The peak inhibition of DPP-4 exceeded 93% across doses of 12.5 mg to 800 mg. Inhibition of DPP-4 remained above 80% at 24 hours for doses greater than or equal to 25 mg. Peak and total exposure over 24 hours to active GLP-1 were three to four fold greater with alogliptin tablets (at doses of 25 to 200 mg) than placebo. In 16 week, double-blind, placebo-controlled study, alogliptin tablets 25 mg demonstrated decreases in postprandial glucagon while increasing postprandial active GLP-1 levels compared to placebo over an eight hour period following standardized meal. It is unclear how these findings relate to changes in overall glycemic control in patients with type diabetes mellitus. In this study, alogliptin tablets 25 mg demonstrated decreases in two hour postprandial glucose compared to placebo (-30 mg/dL versus 17 mg/dL, respectively).Multiple-dose administration of alogliptin to patients with type diabetes also resulted in peak inhibition of DPP-4 within one to two hours and exceeded 93% across all doses (25 mg, 100 mg and 400 mg) after single dose and after 14 days of once-daily dosing. At these doses of alogliptin tablets, inhibition of DPP-4 remained above 81% at 24 hours after 14 days of dosing.. Cardiac ElectrophysiologyIn randomized, placebo-controlled, four-arm, parallel-group study, 257 subjects were administered either alogliptin 50 mg, alogliptin 400 mg, moxifloxacin 400 mg or placebo once daily for total of seven days. No increase in corrected QT (QTc) was observed with either dose of alogliptin. At the 400 mg dose, peak alogliptin plasma concentrations were 19 fold higher than the peak concentrations following the maximum recommended clinical dose of 25 mg.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. The pharmacokinetics of alogliptin tablets has been studied in healthy subjects and in patients with type diabetes. After administration of single, oral doses up to 800 mg in healthy subjects, the peak plasma alogliptin concentration (median Tmax) occurred one to two hours after dosing. At the maximum recommended clinical dose of 25 mg, alogliptin tablets were eliminated with mean terminal half-life (T1/2) of approximately 21 hours.After multiple-dose administration up to 400 mg for 14 days in patients with type diabetes, accumulation of alogliptin was minimal with an increase in total [e.g., area under the plasma concentration curve (AUC)] and peak (i.e., Cmax) alogliptin exposures of 34% and 9%, respectively. Total and peak exposure to alogliptin increased proportionally across single doses and multiple doses of alogliptin ranging from 25 mg to 400 mg. The intersubject coefficient of variation for alogliptin AUC was 17%. The pharmacokinetics of alogliptin tablets were also shown to be similar in healthy subjects and in patients with type diabetes.. AbsorptionThe absolute bioavailability of alogliptin tablets is approximately 100%. Administration of alogliptin tablets with high-fat meal results in no significant change in total and peak exposure to alogliptin. Alogliptin tablets may therefore be administered with or without food.. DistributionFollowing single, 12.5 mg intravenous infusion of alogliptin to healthy subjects, the volume of distribution during the terminal phase was 417 L, indicating that the drug is well distributed into tissues.Alogliptin is 20% bound to plasma proteins.. MetabolismAlogliptin does not undergo extensive metabolism and 60% to 71% of the dose is excreted as unchanged drug in the urine.Two minor metabolites were detected following administration of an oral dose of [14C] alogliptin, N-demethylated, M-I (less than 1% of the parent compound), and N-acetylated alogliptin, M-II (less than 6% of the parent compound). M-I is an active metabolite and is an inhibitor of DPP-4 similar to the parent molecule; M-II does not display any inhibitory activity toward DPP-4 or other DPP-related enzymes. In vitro data indicate that CYP2D6 and CYP3A4 contribute to the limited metabolism of alogliptin.Alogliptin exists predominantly as the (R)-enantiomer (more than 99%) and undergoes little or no chiral conversion in vivo to the (S)-enantiomer. The (S)-enantiomer is not detectable at the 25 mg dose.. ExcretionThe primary route of elimination of [14C] alogliptin-derived radioactivity occurs via renal excretion (76%) with 13% recovered in the feces, achieving total recovery of 89% of the administered radioactive dose. The renal clearance of alogliptin (9.6 L/hr) indicates some active renal tubular secretion and systemic clearance was 14.0 L/hr.. Special Populations. Renal ImpairmentA single-dose, open-label study was conducted to evaluate the pharmacokinetics of alogliptin 50 mg in patients with chronic renal impairment compared with healthy subjects.In patients with mild renal impairment (creatinine clearance [CrCl] >=60 to <90 mL/min), an approximate 1.2 fold increase in plasma AUC of alogliptin was observed. Because increases of this magnitude are not considered clinically relevant, dose adjustment for patients with mild renal impairment is not recommended.In patients with moderate renal impairment (CrCl >=30 to <60 mL/min), an approximate two fold increase in plasma AUC of alogliptin was observed. To maintain similar systemic exposures of alogliptin tablets to those with normal renal function, the recommended dose is 12.5 mg once daily in patients with moderate renal impairment.In patients with severe renal impairment (CrCl >=15 to <30 mL/min) and end-stage renal disease (ESRD) (CrCl <15 mL/min or requiring dialysis), an approximate three and four fold increase in plasma AUC of alogliptin were observed, respectively. Dialysis removed approximately 7% of the drug during three hour dialysis session. Alogliptin tablets may be administered without regard to the timing of the dialysis. To maintain similar systemic exposures of alogliptin tablets to those with normal renal function, the recommended dose is 6.25 mg once daily in patients with severe renal impairment, as well as in patients with ESRD requiring dialysis.. Hepatic ImpairmentTotal exposure to alogliptin was approximately 10% lower and peak exposure was approximately 8% lower in patients with moderate hepatic impairment (Child-Pugh Grade B) compared to healthy subjects. The magnitude of these reductions is not considered to be clinically meaningful. Patients with severe hepatic impairment (Child-Pugh Grade C) have not been studied. Use caution when administering alogliptin tablets to patients with liver disease [see Use in Specific Populations (8.6) and Warnings and Precautions (5.3)].. GenderNo dose adjustment of alogliptin tablets is necessary based on gender. Gender did not have any clinically meaningful effect on the pharmacokinetics of alogliptin.. GeriatricNo dose adjustment of alogliptin tablets is necessary based on age. Age did not have any clinically meaningful effect on the pharmacokinetics of alogliptin.. PediatricStudies characterizing the pharmacokinetics of alogliptin in pediatric patients have not been performed.. RaceNo dose adjustment of alogliptin tablets is necessary based on race. Race (White, Black, and Asian) did not have any clinically meaningful effect on the pharmacokinetics of alogliptin.. Drug Interactions. In Vitro Assessment of Drug InteractionsIn vitro studies indicate that alogliptin is neither an inducer of CYP1A2, CYP2B6, CYP2C9, CYP2C19 and CYP3A4, nor an inhibitor of CYP1A2, CYP2C8, CYP2C9, CYP2C19, CYP3A4 and CYP2D6 at clinically relevant concentrations.. In Vivo Assessment of Drug Interactions. Effects of Alogliptin on the Pharmacokinetics of Other DrugsIn clinical studies, alogliptin did not meaningfully increase the systemic exposure to the following drugs that are metabolized by CYP isozymes or excreted unchanged in urine (Figure 1). No dose adjustment of alogliptin tablets is recommended based on results of the described pharmacokinetic studies.Figure 1. Effect of Alogliptin on the Pharmacokinetic Exposure to Other DrugsWarfarin was given once daily at stable dose in the range of mg to 10 mg. Alogliptin had no significant effect on the prothrombin time (PT) or International Normalized Ratio (INR).Caffeine (1A2 substrate), tolbutamide (2C9 substrate), dextromethorphan (2D6 substrate), midazolam (3A4 substrate) and fexofenadine (P-gp substrate) were administered as cocktail.. Figure 1. Effects of Other Drugs on the Pharmacokinetics of AlogliptinThere are no clinically meaningful changes in the pharmacokinetics of alogliptin when alogliptin tablets are administered concomitantly with the drugs described below (Figure 2).Figure 2. Effect of Other Drugs on the Pharmacokinetic Exposure of Alogliptin. Figure 2.

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryLimited data with alogliptin in pregnant women are not sufficient to determine drug-associated risk for major birth defects or miscarriage. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations]. No adverse developmental effects were observed when alogliptin was administered to pregnant rats and rabbits during organogenesis at exposures 180 and 149 times the 25 mg clinical dose, respectively, based on plasma drug exposure (AUC) [see Data].The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes with HbA1c >7 and has been reported to be as high as 20-25% 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 2-4% and 15-20%, respectively. Clinical Considerations. Disease-associated maternal and/or embryo/fetal riskPoorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, still birth and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, still birth, and macrosomia related morbidity.. Data. Animal DataAlogliptin administered to pregnant rabbits and rats during the period of organogenesis did not cause adverse developmental effects at doses of up to 200 mg/kg and 500 mg/kg, or 149 times and 180 times, the 25 mg clinical dose, respectively, based on plasma drug exposure (AUC).Placental transfer of alogliptin into the fetus was observed following oral dosing to pregnant rats.No adverse developmental outcomes were observed in offspring when alogliptin was administered to pregnant rats during gestation and lactation at doses up to 250 mg/kg (~ 95 times the 25 mg clinical dose, based on AUC).

SPL UNCLASSIFIED SECTION.

1.1Monotherapy and Combination Therapy. Alogliptin tablets are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type diabetes mellitus [see Clinical Studies (14)]. Important Limitations of UseAlogliptin tablets are not indicated for the treatment of type diabetes mellitus or diabetic ketoacidosis, as it would not be effective in these settings.

TERATOGENIC EFFECTS SECTION.

Animal DataAlogliptin administered to pregnant rabbits and rats during the period of organogenesis did not cause adverse developmental effects at doses of up to 200 mg/kg and 500 mg/kg, or 149 times and 180 times, the 25 mg clinical dose, respectively, based on plasma drug exposure (AUC).Placental transfer of alogliptin into the fetus was observed following oral dosing to pregnant rats.No adverse developmental outcomes were observed in offspring when alogliptin was administered to pregnant rats during gestation and lactation at doses up to 250 mg/kg (~ 95 times the 25 mg clinical dose, based on AUC).

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS. 8.1 Pregnancy. Risk SummaryLimited data with alogliptin in pregnant women are not sufficient to determine drug-associated risk for major birth defects or miscarriage. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations]. No adverse developmental effects were observed when alogliptin was administered to pregnant rats and rabbits during organogenesis at exposures 180 and 149 times the 25 mg clinical dose, respectively, based on plasma drug exposure (AUC) [see Data].The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes with HbA1c >7 and has been reported to be as high as 20-25% 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 2-4% and 15-20%, respectively. Clinical Considerations. Disease-associated maternal and/or embryo/fetal riskPoorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, still birth and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, still birth, and macrosomia related morbidity.. Data. Animal DataAlogliptin administered to pregnant rabbits and rats during the period of organogenesis did not cause adverse developmental effects at doses of up to 200 mg/kg and 500 mg/kg, or 149 times and 180 times, the 25 mg clinical dose, respectively, based on plasma drug exposure (AUC).Placental transfer of alogliptin into the fetus was observed following oral dosing to pregnant rats.No adverse developmental outcomes were observed in offspring when alogliptin was administered to pregnant rats during gestation and lactation at doses up to 250 mg/kg (~ 95 times the 25 mg clinical dose, based on AUC).. 8.2 Lactation. Risk SummaryThere is no information regarding the presence of alogliptin in human milk, the effects on the breastfed infant, or the effects on milk production. Alogliptin is present in rat milk: however, due to species specific differences in lactation physiology, animal lactation data may not reliably predict levels in human milk. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for alogliptin tablets and any potential adverse effects on the breastfed infant from alogliptin tablets or from the underlying maternal condition.. 8.4 Pediatric Use. Safety and effectiveness of alogliptin tablets in pediatric patients have not been established.. 8.5 Geriatric Use. Of the total number of patients (N=9052) in clinical safety and efficacy studies treated with alogliptin tablets, 2257 (24.9%) patients were 65 years and older and 386 (4.3%) patients were 75 years and older. No overall differences in safety or effectiveness were observed between patients 65 years and over and younger patients. While this clinical experience has not identified differences in responses between the elderly and younger patients, greater sensitivity of some older individuals cannot be ruled out.. 8.6Renal Impairment. total of 602 patients with moderate renal impairment (eGFR >=30 and <60 mL/min/1.73 m2) and patients with severe renal impairment/end-stage renal disease (eGFR <30 mL/min/1.73 m2 or <15 mL/min/1.73 m2, respectively) at baseline were treated with alogliptin tablets in clinical trials in patients with type diabetes. Reductions in HbA1c were generally similar in this subgroup of patients. The overall incidence of adverse reactions was generally balanced between alogliptin tablets and placebo treatments in this subgroup of patients.In the EXAMINE trial of high CV risk type diabetes patients, 694 patients had moderate renal impairment and 78 patients had severe renal impairment or end-stage renal disease at baseline. The overall incidences of adverse reactions, serious adverse reactions and adverse reactions leading to study drug discontinuation were generally similar between the treatment groups.. 8.7Hepatic Impairment. No dose adjustments are required in patients with mild to moderate hepatic impairment (Child-Pugh Grade and B) based on insignificant change in systemic exposures (e.g., AUC) compared to subjects with normal hepatic function in pharmacokinetic study. Alogliptin tablets have not been studied in patients with severe hepatic impairment (Child-Pugh Grade C). Use caution when administering alogliptin tablets to patients with liver disease [see Warnings and Precautions (5.3)].

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Acute pancreatitis: There have been postmarketing reports of acute pancreatitis. If pancreatitis is suspected, promptly discontinue alogliptin tablets. (5.1)Heart failure: Consider the risks and benefits of alogliptin tablets prior to initiating treatment in patients at risk for heart failure. If heart failure develops, evaluate and manage according to current standards of care and consider discontinuation of alogliptin tablets (5.2).Hypersensitivity: There have been postmarketing reports of serious hypersensitivity reactions in patients treated with alogliptin tablets such as anaphylaxis, angioedema and severe cutaneous adverse reactions, including Stevens-Johnson syndrome. In such cases, promptly discontinue alogliptin tablets, assess for other potential causes, institute appropriate monitoring and treatment and initiate alternative treatment for diabetes. (5.3)Hepatic effects: Postmarketing reports of hepatic failure, sometimes fatal. Causality cannot be excluded. If liver injury is detected, promptly interrupt alogliptin tablets and assess patient for probable cause, then treat cause if possible, to resolution or stabilization. Do not restart alogliptin tablets if liver injury is confirmed and no alternative etiology can be found. (5.4)Hypoglycemia: When an insulin secretagogue (e.g., sulfonylurea) or insulin is used in combination with alogliptin tablets, lower dose of the insulin secretagogue or insulin may be required to minimize the risk of hypoglycemia. (5.5)Arthralgia: Severe and disabling arthralgia has been reported in patients taking DPP-4 inhibitors. Consider as possible cause for severe joint pain and discontinue drug if appropriate. (5.6)Bullous pemphigoid: There have been postmarketing reports of bullous pemphigoid requiring hospitalization in patients taking DPP-4 inhibitors. Tell patients to report development of blisters or erosions. If bullous pemphigoid is suspected, discontinue alogliptin tablets. (5.7)Macrovascular outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with alogliptin tablets or any other antidiabetic drug. (5.8). Acute pancreatitis: There have been postmarketing reports of acute pancreatitis. If pancreatitis is suspected, promptly discontinue alogliptin tablets. (5.1). Heart failure: Consider the risks and benefits of alogliptin tablets prior to initiating treatment in patients at risk for heart failure. If heart failure develops, evaluate and manage according to current standards of care and consider discontinuation of alogliptin tablets (5.2).. Hypersensitivity: There have been postmarketing reports of serious hypersensitivity reactions in patients treated with alogliptin tablets such as anaphylaxis, angioedema and severe cutaneous adverse reactions, including Stevens-Johnson syndrome. In such cases, promptly discontinue alogliptin tablets, assess for other potential causes, institute appropriate monitoring and treatment and initiate alternative treatment for diabetes. (5.3). Hepatic effects: Postmarketing reports of hepatic failure, sometimes fatal. Causality cannot be excluded. If liver injury is detected, promptly interrupt alogliptin tablets and assess patient for probable cause, then treat cause if possible, to resolution or stabilization. Do not restart alogliptin tablets if liver injury is confirmed and no alternative etiology can be found. (5.4). Hypoglycemia: When an insulin secretagogue (e.g., sulfonylurea) or insulin is used in combination with alogliptin tablets, lower dose of the insulin secretagogue or insulin may be required to minimize the risk of hypoglycemia. (5.5). Arthralgia: Severe and disabling arthralgia has been reported in patients taking DPP-4 inhibitors. Consider as possible cause for severe joint pain and discontinue drug if appropriate. (5.6). Bullous pemphigoid: There have been postmarketing reports of bullous pemphigoid requiring hospitalization in patients taking DPP-4 inhibitors. Tell patients to report development of blisters or erosions. If bullous pemphigoid is suspected, discontinue alogliptin tablets. (5.7). Macrovascular outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with alogliptin tablets or any other antidiabetic drug. (5.8). 5.1Pancreatitis. Acute pancreatitis has been reported in the postmarketing setting and in randomized clinical trials. In glycemic control trials in patients with type diabetes, acute pancreatitis was reported in (0.2%) patients treated with alogliptin tablets 25 mg and (<0.1%) patients treated with active comparators or placebo. In the EXAMINE trial (a cardiovascular outcomes trial of patients with type diabetes and high cardiovascular (CV) risk), acute pancreatitis was reported in 10 (0.4%) of patients treated with alogliptin tablets and in (0.3%) of patients treated with placebo.It is unknown whether patients with history of pancreatitis are at increased risk for pancreatitis while using alogliptin tablets. After initiation of alogliptin tablets, patients should be observed for signs and symptoms of pancreatitis. If pancreatitis is suspected, alogliptin tablets should promptly be discontinued and appropriate management should be initiated.. 5.2Heart Failure. In the EXAMINE trial which enrolled patients with type diabetes and recent acute coronary syndrome, 106 (3.9%) of patients treated with alogliptin tablets and 89 (3.3%) of patients treated with placebo were hospitalized for congestive heart failure.Consider the risks and benefits of alogliptin tablets prior to initiating treatment in patients at risk for heart failure, such as those with prior history of heart failure and history of renal impairment, and observe these patients for signs and symptoms of heart failure during therapy. Patients should be advised of the characteristic symptoms of heart failure and should be instructed to immediately report such symptoms. If heart failure develops, evaluate and manage according to current standards of care and consider discontinuation of alogliptin tablets.. 5.3Hypersensitivity Reactions. There have been postmarketing reports of serious hypersensitivity reactions in patients treated with alogliptin tablets. These reactions include anaphylaxis, angioedema and severe cutaneous adverse reactions, including Stevens-Johnson syndrome. If serious hypersensitivity reaction is suspected, discontinue alogliptin tablets, assess for other potential causes for the event and institute alternative treatment for diabetes [see Adverse Reactions (6.2)]. Use caution in patients with history of angioedema with another dipeptidyl peptidase-4 (DPP-4) inhibitor because it is unknown whether such patients will be predisposed to angioedema with alogliptin tablets.. 5.4Hepatic Effects. There have been postmarketing reports of fatal and nonfatal hepatic failure in patients taking alogliptin tablets, although some of the reports contain insufficient information necessary to establish the probable cause [see Adverse Reactions (6.2)].In glycemic control trials in patients with type diabetes, serum alanine aminotransferase (ALT) elevations greater than three times the upper limit of normal (ULN) were reported in 1.3% of patients treated with alogliptin tablets 25 mg and 1.7% of patients treated with active comparators or placebo. In the EXAMINE trial (a cardiovascular outcomes trial of patients with type diabetes and high cardiovascular (CV) risk), increases in serum alanine aminotransferase three times the upper limit of the reference range occurred in 2.4% of patients treated with alogliptin tablets and in 1.8% of patients treated with placebo.Measure liver tests promptly in patients who report symptoms that may indicate liver injury, including fatigue, anorexia, right upper abdominal discomfort, dark urine or jaundice. In this clinical context, if the patient is found to have clinically significant liver enzyme elevations and if abnormal liver tests persist or worsen, alogliptin tablets should be interrupted and investigation done to establish the probable cause. Alogliptin tablets should not be restarted in these patients without another explanation for the liver test abnormalities.. 5.5Use with Medications Known to Cause Hypoglycemia. Insulin and insulin secretagogues, such as sulfonylureas, are known to cause hypoglycemia. Therefore, lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used in combination with alogliptin tablets.. 5.6Severe and Disabling Arthralgia. There have been postmarketing reports of severe and disabling arthralgia in patients taking DPP-4 inhibitors. The time to onset of symptoms following initiation of drug therapy varied from one day to years. Patients experienced relief of symptoms upon discontinuation of the medication. subset of patients experienced recurrence of symptoms when restarting the same drug or different DPP-4 inhibitor. Consider DPP-4 inhibitors as possible cause for severe joint pain and discontinue drug if appropriate.. 5.7Bullous Pemphigoid. Postmarketing cases of bullous pemphigoid requiring hospitalization have been reported with DPP-4 inhibitor use. In reported cases, patients typically recovered with topical or systemic immunosuppressive treatment and discontinuation of the DPP-4 inhibitor. Tell patients to report development of blisters or erosions while receiving alogliptin tablets. If bullous pemphigoid is suspected, alogliptin tablets should be discontinued and referral to dermatologist should be considered for diagnosis and appropriate treatment.. 5.8Macrovascular Outcomes. There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with alogliptin tablets or any other antidiabetic drug.
