These Highlights Do Not Include All The Information Needed To Use Alogliptin Tablets Safely And Effectively. See Full Prescribing Information For Alogliptin Tablets.

Animal Data

Alogliptin 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).

Limitations of Use

Alogliptin tablets should not be used in patients with type 1 diabetes mellitus.

In the event of an overdose, it is reasonable to institute the necessary clinical monitoring and supportive therapy as dictated by the patient's clinical status. Per clinical judgment, it may be reasonable to initiate removal of unabsorbed material from the gastrointestinal tract.

Alogliptin is minimally dialyzable; over a 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.

Alogliptin tablets contain the active ingredient alogliptin, which is a selective, orally bioavailable inhibitor of the enzymatic activity of dipeptidyl peptidase-4 (DPP-4).

Chemically, alogliptin is prepared as a benzoate salt, which is identified as 2-({6-[(3R)-3-aminopiperidin-1-yl]-3-methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl}methyl)benzonitrile monobenzoate. It has a molecular formula of C₁₈H₂₁N₅O₂∙C₇H₆O₂ and a molecular weight of 461.51 daltons. The structural formula is:

Alogliptin benzoate is a white to off-white crystalline powder containing one asymmetric carbon in the aminopiperidine moiety. It is soluble in dimethylsulfoxide, sparingly soluble in water and methanol, slightly soluble in ethanol and very slightly soluble in octanol and isopropyl acetate.

Each alogliptin tablet contains 34 mg, 17 mg or 8.5 mg alogliptin benzoate, which is equivalent to 25 mg, 12.5 mg or 6.25 mg, respectively, of alogliptin and the following inactive ingredients: mannitol, microcrystalline cellulose, hydroxypropyl cellulose, croscarmellose sodium and magnesium stearate. In addition, the film coating contains the following inactive ingredients: hypromellose, titanium dioxide, ferric oxide (red or yellow) and polyethylene glycol, and is marked with printing ink (Gray F1).

Acute pancreatitis has been reported in the postmarketing setting and in randomized clinical trials. In glycemic control trials in patients with type 2 diabetes, acute pancreatitis was reported in 6 (0.2%) patients treated with alogliptin tablets 25 mg and 2 (<0.1%) patients treated with active comparators or placebo. In the EXAMINE trial (a cardiovascular outcomes trial of patients with type 2 diabetes and high cardiovascular (CV) risk), acute pancreatitis was reported in 10 (0.4%) of patients treated with alogliptin tablets and in 7 (0.3%) of patients treated with placebo.

It is unknown whether patients with a 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.

In the EXAMINE trial which enrolled patients with type 2 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 a prior history of heart failure and a 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.

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

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.

Alogliptin tablets have been studied as monotherapy and in combination with metformin, a sulfonylurea, a thiazolidinedione (either alone or in combination with metformin or a sulfonylurea) and insulin (either alone or in combination with metformin).

A total of 14,053 patients with type 2 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 2 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 2 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.

Serious hypersensitivity reaction to alogliptin or any of the excipients in Alogliptin tablets. Reactions such as anaphylaxis, angioedema and severe cutaneous adverse reactions have been reported [see Warnings and Precautions (5.3), Adverse Reactions (6.2)].

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 2 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 2 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.

The following serious adverse reactions are described below or elsewhere in the prescribing information:

• Pancreatitis [see Warnings and Precautions (5.1)]
• Heart Failure [see Warnings and Precautions (5.2)]
• Hypersensitivity Reactions [see Warnings and Precautions (5.3)]
• Hepatic Effects [see Warnings and Precautions (5.4)]
• Severe and Disabling Arthralgia [see Warnings and Precautions (5.6)]
• Bullous Pemphigoid [see Warnings and Precautions (5.7)]

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)].

A total of 602 patients with moderate renal impairment (eGFR ≥30 and <60 mL/min/1.73 m²) and 4 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 2 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 2 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.

Single-dose administration of alogliptin tablets to healthy subjects resulted in a 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 a 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 a standardized meal. It is unclear how these findings relate to changes in overall glycemic control in patients with type 2 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 2 diabetes also resulted in a peak inhibition of DPP-4 within one to two hours and exceeded 93% across all doses (25 mg, 100 mg and 400 mg) after a 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.

The pharmacokinetics of alogliptin tablets has been studied in healthy subjects and in patients with type 2 diabetes. After administration of single, oral doses up to 800 mg in healthy subjects, the peak plasma alogliptin concentration (median T_max) occurred one to two hours after dosing. At the maximum recommended clinical dose of 25 mg, alogliptin tablets were eliminated with a mean terminal half-life (T_1/2) of approximately 21 hours.

After multiple-dose administration up to 400 mg for 14 days in patients with type 2 diabetes, accumulation of alogliptin was minimal with an increase in total [e.g., area under the plasma concentration curve (AUC)] and peak (i.e., C_max) 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 2 diabetes.

The recommended dose of alogliptin tablets is 25 mg once daily. Alogliptin tablets may be taken with or without food. Do not split tablets.

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 a dermatologist should be considered for diagnosis and appropriate treatment.

No dose adjustments are required in patients with mild to moderate hepatic impairment (Child-Pugh Grade A and B) based on insignificant change in systemic exposures (e.g., AUC) compared to subjects with normal hepatic function in a 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 (5.4)].

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)].

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 a 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 2 diabetes, concentrations of GLP-1 are reduced but the insulin response to GLP-1 is preserved. Alogliptin is a DPP-4 inhibitor that slows the inactivation of the incretin hormones, thereby increasing their bloodstream concentrations and reducing fasting and postprandial glucose concentrations in a glucose-dependent manner in patients with type 2 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.

• 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, a 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 a 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)

• 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)

• 25 mg tablets are light red, oval, biconvex, film-coated, with "TAK ALG-25" printed on one side.
• 12.5 mg tablets are yellow, oval, biconvex, film-coated, with "TAK ALG-12.5" printed on one side.
• 6.25 mg tablets are light pink, oval, biconvex, film-coated, with "TAK ALG-6.25" printed on one side.

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

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 a 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 a 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.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a 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 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/m² (49% of patients had a 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 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.

A randomized, double-blind, placebo-controlled cardiovascular outcomes trial (EXAMINE) was conducted to evaluate the cardiovascular risk of alogliptin tablets. 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 a sufficient number of primary outcome events accrued.

Eligible patients were adults with type 2 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 a diagnosis of type 2 diabetes mellitus for approximately 9 years, 87% had a 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 a MACE defined as the composite of cardiovascular death, nonfatal myocardial infarction (MI), or nonfatal stroke. The study was designed to exclude a 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 a risk margin larger than 1.3.

The Kaplan-Meier based cumulative event probability is presented in Figure 4 for the time to first occurrence of the primary MACE composite endpoint by treatment arm. The curves for placebo and alogliptin tablets overlap throughout the duration of the study. The observed incidence of MACE was highest within the first 60 days after randomization in both treatment arms (14.8 MACE per 100 PY), decreased from day 60 to the end of the first year (8.4 per 100 PY) and was lowest after one year of follow-up (5.2 per 100 PY).

The rate of all cause death was similar between treatment arms with 153 (3.6 per 100 PY) recorded among patients randomized to alogliptin tablets and 173 (4.1 per 100 PY) among patients randomized to placebo. A total of 112 deaths (2.9 per 100 PY) among patients on alogliptin tablets and 130 among patients on placebo (3.5 per 100 PY) were adjudicated as cardiovascular deaths.

Advise the patient to read the FDA-approved patient labeling (Medication Guide).

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.

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. A subset of patients experienced a recurrence of symptoms when restarting the same drug or a different DPP-4 inhibitor. Consider DPP-4 inhibitors as a possible cause for severe joint pain and discontinue drug if appropriate.

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), a 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 a 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).

A total of 1768 patients with type 2 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 a four week, single-blind, placebo run-in period followed by a 26 week randomized treatment period. Patients who failed to meet prespecified hyperglycemic goals during the 26 week treatment periods received glycemic rescue therapy.

In a 26 week, double-blind, placebo-controlled study, a 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). A 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.

In a 26-week, double-blind, active-controlled study, a total of 655 patients (mean baseline A1C = 8.8%) were randomized to receive alogliptin tablets 25 mg alone, pioglitazone 30 mg alone, alogliptin tablets 12.5 mg with pioglitazone 30 mg or alogliptin tablets 25 mg with pioglitazone 30 mg once daily. Coadministration of alogliptin tablets 25 mg with pioglitazone 30 mg resulted in statistically significant improvements from baseline in A1C and FPG compared to alogliptin tablets 25 mg alone and to pioglitazone 30 mg alone (Table 4). A total of 3% of patients receiving alogliptin tablets 25 mg coadministered with pioglitazone 30 mg, 11% of those receiving alogliptin tablets 25 mg alone and 6% of those receiving pioglitazone 30 mg alone required glycemic rescue.

Improvements in A1C were not affected by gender, age or baseline BMI.

The mean increase in body weight was similar between pioglitazone alone and alogliptin tablets when coadministered with pioglitazone.

In a 26 week, double-blind, placebo-controlled study, a total of 784 patients inadequately controlled on diet and exercise alone (mean baseline A1C = 8.4%) were randomized to one of seven treatment groups: placebo; metformin HCl 500 mg or metformin HCl 1000 mg twice daily; alogliptin tablets 12.5 mg twice daily; alogliptin tablets 25 mg daily; or alogliptin tablets 12.5 mg in combination with metformin HCl 500 mg or metformin HCl 1000 mg twice daily. 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). A 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.

Insulin and insulin secretagogues, such as sulfonylureas, are known to cause hypoglycemia. Therefore, a lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used in combination with alogliptin tablets.

Animal Data

Alogliptin 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).

Limitations of Use

Alogliptin tablets should not be used in patients with type 1 diabetes mellitus.

In the event of an overdose, it is reasonable to institute the necessary clinical monitoring and supportive therapy as dictated by the patient's clinical status. Per clinical judgment, it may be reasonable to initiate removal of unabsorbed material from the gastrointestinal tract.

Alogliptin is minimally dialyzable; over a 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.

Alogliptin tablets contain the active ingredient alogliptin, which is a selective, orally bioavailable inhibitor of the enzymatic activity of dipeptidyl peptidase-4 (DPP-4).

Chemically, alogliptin is prepared as a benzoate salt, which is identified as 2-({6-[(3R)-3-aminopiperidin-1-yl]-3-methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl}methyl)benzonitrile monobenzoate. It has a molecular formula of C₁₈H₂₁N₅O₂∙C₇H₆O₂ and a molecular weight of 461.51 daltons. The structural formula is:

Alogliptin benzoate is a white to off-white crystalline powder containing one asymmetric carbon in the aminopiperidine moiety. It is soluble in dimethylsulfoxide, sparingly soluble in water and methanol, slightly soluble in ethanol and very slightly soluble in octanol and isopropyl acetate.

Each alogliptin tablet contains 34 mg, 17 mg or 8.5 mg alogliptin benzoate, which is equivalent to 25 mg, 12.5 mg or 6.25 mg, respectively, of alogliptin and the following inactive ingredients: mannitol, microcrystalline cellulose, hydroxypropyl cellulose, croscarmellose sodium and magnesium stearate. In addition, the film coating contains the following inactive ingredients: hypromellose, titanium dioxide, ferric oxide (red or yellow) and polyethylene glycol, and is marked with printing ink (Gray F1).

Acute pancreatitis has been reported in the postmarketing setting and in randomized clinical trials. In glycemic control trials in patients with type 2 diabetes, acute pancreatitis was reported in 6 (0.2%) patients treated with alogliptin tablets 25 mg and 2 (<0.1%) patients treated with active comparators or placebo. In the EXAMINE trial (a cardiovascular outcomes trial of patients with type 2 diabetes and high cardiovascular (CV) risk), acute pancreatitis was reported in 10 (0.4%) of patients treated with alogliptin tablets and in 7 (0.3%) of patients treated with placebo.

It is unknown whether patients with a 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.

In the EXAMINE trial which enrolled patients with type 2 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 a prior history of heart failure and a 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.

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

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.

Alogliptin tablets have been studied as monotherapy and in combination with metformin, a sulfonylurea, a thiazolidinedione (either alone or in combination with metformin or a sulfonylurea) and insulin (either alone or in combination with metformin).

A total of 14,053 patients with type 2 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 2 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 2 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.

Serious hypersensitivity reaction to alogliptin or any of the excipients in Alogliptin tablets. Reactions such as anaphylaxis, angioedema and severe cutaneous adverse reactions have been reported [see Warnings and Precautions (5.3), Adverse Reactions (6.2)].

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 2 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 2 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.

The following serious adverse reactions are described below or elsewhere in the prescribing information:

• Pancreatitis [see Warnings and Precautions (5.1)]
• Heart Failure [see Warnings and Precautions (5.2)]
• Hypersensitivity Reactions [see Warnings and Precautions (5.3)]
• Hepatic Effects [see Warnings and Precautions (5.4)]
• Severe and Disabling Arthralgia [see Warnings and Precautions (5.6)]
• Bullous Pemphigoid [see Warnings and Precautions (5.7)]

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)].

A total of 602 patients with moderate renal impairment (eGFR ≥30 and <60 mL/min/1.73 m²) and 4 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 2 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 2 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.

Single-dose administration of alogliptin tablets to healthy subjects resulted in a 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 a 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 a standardized meal. It is unclear how these findings relate to changes in overall glycemic control in patients with type 2 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 2 diabetes also resulted in a peak inhibition of DPP-4 within one to two hours and exceeded 93% across all doses (25 mg, 100 mg and 400 mg) after a 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.

The pharmacokinetics of alogliptin tablets has been studied in healthy subjects and in patients with type 2 diabetes. After administration of single, oral doses up to 800 mg in healthy subjects, the peak plasma alogliptin concentration (median T_max) occurred one to two hours after dosing. At the maximum recommended clinical dose of 25 mg, alogliptin tablets were eliminated with a mean terminal half-life (T_1/2) of approximately 21 hours.

After multiple-dose administration up to 400 mg for 14 days in patients with type 2 diabetes, accumulation of alogliptin was minimal with an increase in total [e.g., area under the plasma concentration curve (AUC)] and peak (i.e., C_max) 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 2 diabetes.

The recommended dose of alogliptin tablets is 25 mg once daily. Alogliptin tablets may be taken with or without food. Do not split tablets.

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 a dermatologist should be considered for diagnosis and appropriate treatment.

No dose adjustments are required in patients with mild to moderate hepatic impairment (Child-Pugh Grade A and B) based on insignificant change in systemic exposures (e.g., AUC) compared to subjects with normal hepatic function in a 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 (5.4)].

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)].

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 a 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 2 diabetes, concentrations of GLP-1 are reduced but the insulin response to GLP-1 is preserved. Alogliptin is a DPP-4 inhibitor that slows the inactivation of the incretin hormones, thereby increasing their bloodstream concentrations and reducing fasting and postprandial glucose concentrations in a glucose-dependent manner in patients with type 2 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.

• 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, a 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 a 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)

• 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)

• 25 mg tablets are light red, oval, biconvex, film-coated, with "TAK ALG-25" printed on one side.
• 12.5 mg tablets are yellow, oval, biconvex, film-coated, with "TAK ALG-12.5" printed on one side.
• 6.25 mg tablets are light pink, oval, biconvex, film-coated, with "TAK ALG-6.25" printed on one side.

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

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 a 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 a 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.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a 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 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/m² (49% of patients had a 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 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.

A randomized, double-blind, placebo-controlled cardiovascular outcomes trial (EXAMINE) was conducted to evaluate the cardiovascular risk of alogliptin tablets. 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 a sufficient number of primary outcome events accrued.

Eligible patients were adults with type 2 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 a diagnosis of type 2 diabetes mellitus for approximately 9 years, 87% had a 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 a MACE defined as the composite of cardiovascular death, nonfatal myocardial infarction (MI), or nonfatal stroke. The study was designed to exclude a 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 a risk margin larger than 1.3.

The Kaplan-Meier based cumulative event probability is presented in Figure 4 for the time to first occurrence of the primary MACE composite endpoint by treatment arm. The curves for placebo and alogliptin tablets overlap throughout the duration of the study. The observed incidence of MACE was highest within the first 60 days after randomization in both treatment arms (14.8 MACE per 100 PY), decreased from day 60 to the end of the first year (8.4 per 100 PY) and was lowest after one year of follow-up (5.2 per 100 PY).

The rate of all cause death was similar between treatment arms with 153 (3.6 per 100 PY) recorded among patients randomized to alogliptin tablets and 173 (4.1 per 100 PY) among patients randomized to placebo. A total of 112 deaths (2.9 per 100 PY) among patients on alogliptin tablets and 130 among patients on placebo (3.5 per 100 PY) were adjudicated as cardiovascular deaths.

Advise the patient to read the FDA-approved patient labeling (Medication Guide).

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.

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. A subset of patients experienced a recurrence of symptoms when restarting the same drug or a different DPP-4 inhibitor. Consider DPP-4 inhibitors as a possible cause for severe joint pain and discontinue drug if appropriate.

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), a 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 a 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).

A total of 1768 patients with type 2 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 a four week, single-blind, placebo run-in period followed by a 26 week randomized treatment period. Patients who failed to meet prespecified hyperglycemic goals during the 26 week treatment periods received glycemic rescue therapy.

In a 26 week, double-blind, placebo-controlled study, a 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). A 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.

In a 26-week, double-blind, active-controlled study, a total of 655 patients (mean baseline A1C = 8.8%) were randomized to receive alogliptin tablets 25 mg alone, pioglitazone 30 mg alone, alogliptin tablets 12.5 mg with pioglitazone 30 mg or alogliptin tablets 25 mg with pioglitazone 30 mg once daily. Coadministration of alogliptin tablets 25 mg with pioglitazone 30 mg resulted in statistically significant improvements from baseline in A1C and FPG compared to alogliptin tablets 25 mg alone and to pioglitazone 30 mg alone (Table 4). A total of 3% of patients receiving alogliptin tablets 25 mg coadministered with pioglitazone 30 mg, 11% of those receiving alogliptin tablets 25 mg alone and 6% of those receiving pioglitazone 30 mg alone required glycemic rescue.

Improvements in A1C were not affected by gender, age or baseline BMI.

The mean increase in body weight was similar between pioglitazone alone and alogliptin tablets when coadministered with pioglitazone.

In a 26 week, double-blind, placebo-controlled study, a total of 784 patients inadequately controlled on diet and exercise alone (mean baseline A1C = 8.4%) were randomized to one of seven treatment groups: placebo; metformin HCl 500 mg or metformin HCl 1000 mg twice daily; alogliptin tablets 12.5 mg twice daily; alogliptin tablets 25 mg daily; or alogliptin tablets 12.5 mg in combination with metformin HCl 500 mg or metformin HCl 1000 mg twice daily. 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). A 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.

Insulin and insulin secretagogues, such as sulfonylureas, are known to cause hypoglycemia. Therefore, a lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used in combination with alogliptin tablets.
