Oseni Side Effects Center
Pharmacy Editor: Melissa Conrad Stöppler, MD
Oseni (alogliptin and pioglitazone) is used to treat and manage type 2 diabetes. Oseni is a combination antidiabetic medication. Oseni can cause serious side effects in some patients, including new or worsening heart failure, fluid retention (especially in the legs and ankles), swelling and weight gain.
Oseni is available as a tablet in the following strengths: 25 mg alogliptin and 15 mg pioglitazone, 25 mg alogliptin and 30 mg pioglitazone, 25 mg alogliptin and 45 mg pioglitazone. (3) 12.5 mg alogliptin and 15 mg pioglitazone, 12.5 mg alogliptin and 30 mg pioglitazone, 12.5 mg alogliptin and 45 mg pioglitazone. Oseni may result in ovulation in some premenopausal women who no longer ovulate. As a result, premenopausal women may be at risk for pregnancy. Adequate contraception in all premenopausal women treated with Oseni is recommended. Oseni should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether the components of Oseni (alogliptin and/or pioglitazone) are secreted in human milk. Because many drugs are excreted in human milk, and because of the potential for Oseni to cause serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or discontinue Oseni, taking into account the importance of Oseni to the mother.
Our Oseni (alogliptin and pioglitazone) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

Clinical Studies Experience
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 clinical practice.
Alogliptin and Pioglitazone
Over 1500 patients with type 2 diabetes have received alogliptin coadministered with pioglitazone in four large randomized, double-blind controlled clinical trials. The mean exposure to OSENI was 29 weeks with more than 100 subjects treated for more than one year. The studies consisted of two placebo-controlled studies of 16 to 26 weeks duration and two active-controlled studies of 26 weeks and 52 weeks in duration. In the OSENI arm, the mean duration of diabetes was approximately 6 years, the mean body mass index (BMI) was 31 kg/m² (54% of patients had a BMI > 30 kg/m²), and the mean age was 54 years (16% of patients > 65 years of age).
In a pooled analysis of these four controlled clinical studies, the overall incidence of adverse events was 65% in patients treated with OSENI compared to 57% treated with placebo. Overall discontinuation of therapy due to adverse events was 2.5% with OSENI compared to 2.0% with placebo, 3.7% with pioglitazone or 1.3% with alogliptin.
Adverse reactions reported in ≥ 4% of patients treated with OSENI and more frequently than in patients who received alogliptin, pioglitazone or placebo are summarized in Table 1.

Alogliptin Add-on Therapy to a Thiazolidinedione
In addition, in a 26-week, placebo-controlled, double-blind study, patients inadequately controlled on a thiazolidinedione alone or in combination with metformin or a sulfonylurea were treated with add-on alogliptin therapy or placebo; the adverse reactions reported in ≥ 5% of patients and more frequently than in patients who received placebo was influenza (alogliptin, 5.5%; placebo, 4.1%).
In a 26-week placebo-controlled factorial study with alogliptin in combination with pioglitazone on background therapy with metformin, the incidence of subjects reporting hypoglycemia was 0.8%, 0%, 3.8% for alogliptin 25 mg with pioglitazone 15 mg, 30 mg, or 45 mg, respectively; 2.3% for alogliptin 25 mg; 4.7%, 0.8%, 0.8% for pioglitazone 15 mg, 30 mg, or 45 mg, respectively; and 0.8% for placebo.
In a 26-week, active-controlled, double-blind study with alogliptin alone, pioglitazone alone or alogliptin coadministered with pioglitazone in patients inadequately controlled on diet and exercise, the incidence of hypoglycemia was 3% on alogliptin 25 mg with pioglitazone 30 mg, 0.6% on alogliptin 25 mg, and 1.8% on pioglitazone 30 mg.
In a 52-week, active-controlled, double-blind study of alogliptin as add-on therapy to the combination of pioglitazone 30 mg and metformin compared to the titration of pioglitazone 30 mg to 45 mg and metformin, the incidence of subjects reporting hypoglycemia was 4.5% in the alogliptin 25 mg with pioglitazone 30 mg and metformin group versus 1.5% in the pioglitazone 45 mg and metformin group.
Approximately 8500 patients with type 2 diabetes have been treated with alogliptin in 14 randomized, double-blind, controlled clinical trials with approximately 2900 subjects randomized to placebo and approximately 2200 to an active comparator. The mean exposure to alogliptin was 40 weeks with more than 2400 subjects treated for more than one year. Among these patients, 63% had a history of hypertension, 51% had a history of dyslipidemia, 25% had a history of myocardial infarction, 8% had a history of unstable angina, and 7% had a history of congestive heart failure. The mean duration of diabetes was 7 years, the mean body mass index (BMI) was 31 kg/m² (51% of patients had a BMI ≥ 30 kg/m²), and the mean age was 57 years (24% of patients ≥ 65 years of age). Two placebo-controlled monotherapy trials of 12 and 26 weeks of duration were conducted in patients treated with alogliptin 12.5 mg daily, alogliptin 25 mg daily and placebo. Four placebo-controlled add-on combination therapy trials of 26 weeks duration were also conducted: with metformin, with a sulfonylurea, with a thiazolidinedione, and with insulin.
Five placebo-controlled trials of 16 weeks up through two years in duration were conducted in combination with metformin, in combination with pioglitazone and with pioglitazone added to a background of metformin therapy.
Three active-controlled trials of 52 weeks in duration were conducted in patients treated with pioglitazone and metformin, in combination with metformin and as monotherapy compared to glipizide.
In a pooled analysis of these 14 controlled clinical trials, the overall incidence of adverse events was 66% in patients treated with alogliptin 25 mg compared to 62% with placebo and 70% with active comparator. Overall discontinuation of therapy due to adverse events was 4.7% with alogliptin 25 mg compared to 4.5% with placebo or 6.2% with active comparator.
Adverse reactions reported in ≥ 4% of patients treated with alogliptin 25 mg and more frequently than in patients who received placebo are summarized in Table 2.

In the clinical trial program, pancreatitis was reported in 11 of 5902 (0.2%) patients receiving alogliptin 25 mg daily compared to 5 of 5183 ( < 0.1%) patients receiving all comparators.
In a pooled analysis, the overall incidence of hypersensitivity reactions was 0.6% with alogliptin 25 mg compared to 0.8% with all comparators. A single event of serum sickness was reported in a patient treated with alogliptin 25 mg.
Hypoglycemic events were documented based upon a 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 compared to 1.6% with placebo. The use of alogliptin as add-on therapy to glyburide or insulin did not increase the incidence of hypoglycemia compared to placebo. In a monotherapy study comparing alogliptin to a sulfonylurea in elderly patients, the incidence of hypoglycemia was 5.4% with alogliptin compared to 26% with glipizide.
Over 8500 patients with type 2 diabetes have been treated with pioglitazone in randomized, double-blind, controlled clinical trials, including 2605 patients with type 2 diabetes and macrovascular disease treated with pioglitazone in the PROactive clinical trial. In these trials, over 6000 patients have been treated with pioglitazone for 6 months or longer, over 4500 patients have been treated with pioglitazone for one year or longer, and over 3000 patients have been treated with pioglitazone for at least 2 years.
Common Adverse Events: 16- to 26-Week Monotherapy Trials
A summary of the incidence and type of common adverse events reported in three pooled 16- to 26-week placebo-controlled monotherapy trials of pioglitazone is provided in Table 3. Terms that are reported represent those that occurred at an incidence of > 5% and more commonly in patients treated with pioglitazone than in patients who received placebo.

Congestive Heart Failure
A summary of the incidence of adverse events related to congestive heart failure for the 16- to 24-week add-on to sulfonylurea trials, for the 16- to 24-week add-on to insulin trials, and for the 16- to 24-week add-on to metformin trials were (at least one congestive heart failure, 0.2% to 1.7%; hospitalized due to congestive heart failure, 0.2% to 0.9%). None of the events were fatal.
Patients with type 2 diabetes and NYHA class II or early class III congestive heart failure were randomized to receive 24 weeks of double-blind treatment with either pioglitazone at daily doses of 30 mg to 45 mg (N=262) or glyburide at daily doses of 10 mg to 15 mg (N=256). A summary of the incidence of adverse events related to congestive heart failure reported in this study is provided in Table 4.

In the PROactive trial, 5238 patients with type 2 diabetes and a history of macrovascular disease were randomized to pioglitazone (N=2605), force-titrated up to 45 mg daily or placebo (N=2633) in addition to standard of care. Almost all patients (95%) were receiving cardiovascular medications (beta blockers, ACE inhibitors, angiotensin II receptor blockers, calcium channel blockers, nitrates, diuretics, aspirin, statins and fibrates). At baseline, patients had a mean age of 62 years, mean duration of diabetes of 9.5 years, and mean A1C of 8.1%. Mean duration of follow-up was 34.5 months.
The primary objective of this trial was to examine the effect of pioglitazone on mortality and macrovascular morbidity in patients with type 2 diabetes mellitus who were at high risk for macrovascular events. The primary efficacy variable was the time to the first occurrence of any event in a cardiovascular composite endpoint that included all-cause mortality, non-fatal myocardial infarction (MI) including silent MI, stroke, acute coronary syndrome, cardiac intervention including coronary artery bypass grafting or percutaneous intervention, major leg amputation above the ankle, and bypass surgery or revascularization in the leg. A total of 514 (19.7%) patients treated with pioglitazone and 572 (21.7%) placebo-treated patients experienced at least one event from the primary composite endpoint (hazard ratio 0.90; 95% Confidence Interval: 0.80, 1.02; p=0.10).
Although there was no statistically significant difference between pioglitazone and placebo for the 3-year incidence of a first event within this composite, there was no increase in mortality or in total macrovascular events with pioglitazone. The number of first occurrences and total individual events contributing to the primary composite endpoint is shown in Table 6.

Dose-related weight gain occurs when pioglitazone is used alone or in combination with other antidiabetic medications. The mechanism of weight gain is unclear but probably involves a combination of fluid retention and fat accumulation.
Edema induced from taking pioglitazone is reversible when pioglitazone is discontinued. The edema usually does not require hospitalization unless there is coexisting congestive heart failure.
There has been no evidence of pioglitazone-induced hepatotoxicity in the pioglitazone controlled clinical trial database to date. One randomized, double-blind, 3-year trial comparing pioglitazone to glyburide as add-on to metformin and insulin therapy was specifically designed to evaluate the incidence of serum ALT elevation to greater than 3 times the upper limit of the reference range, measured every 8 weeks for the first 48 weeks of the trial then every 12 weeks thereafter. A total of 3/1051 (0.3%) patients treated with pioglitazone and 9/1046 (0.9%) patients treated with glyburide developed ALT values > 3 times the upper limit of the reference range. None of the patients treated with pioglitazone in the pioglitazone controlled clinical trial database to date have had a serum ALT > 3 times the upper limit of the reference range and a corresponding total bilirubin > 2 times the upper limit of the reference range, a combination predictive of the potential for severe drug-induced liver injury.
In the pioglitazone clinical trials, adverse events of hypoglycemia were reported based on clinical judgment of the investigators and did not require confirmation with fingerstick glucose testing. In the 16-week add-on to sulfonylurea trial, the incidence of reported hypoglycemia was 3.7% with pioglitazone 30 mg and 0.5% with placebo. In the 16-week add-on to insulin trial, the incidence of reported hypoglycemia was 7.9% with pioglitazone15 mg, 15.4% with pioglitazone 30 mg, and 4.8% with placebo. The incidence of reported hypoglycemia was higher with pioglitazone 45 mg compared to pioglitazone 30 mg in both the 24-week add-on to sulfonylurea trial (15.7% vs. 13.4%) and in the 24-week add-on to insulin trial (47.8% vs. 43.5%). Three patients in these four trials were hospitalized due to hypoglycemia. All three patients were receiving pioglitazone 30 mg (0.9%) in the 24-week add-on to insulin trial. An additional 14 patients reported severe hypoglycemia (defined as causing considerable interference with patient's usual activities) that did not require hospitalization. These patients were receiving pioglitazone 45 mg in combination with sulfonylurea (N=2) or pioglitazone 30 mg or 45 mg in combination with insulin (N=12).
Urinary Bladder Tumors
Tumors were observed in the urinary bladder of male rats in the two-year carcinogenicity study [see Nonclinical Toxicology]. In two 3-year trials in which pioglitazone was compared to placebo or glyburide, there were 16/3656 (0.44%) reports of bladder cancer in patients taking pioglitazone compared to 5/3679 (0.14%) in patients not taking pioglitazone. After excluding patients in whom exposure to study drug was less than one year at the time of diagnosis of bladder cancer, there were six (0.16%) cases on pioglitazone and two (0.05%) cases on placebo. There are too few events of bladder cancer to establish causality.
Pioglitazone may cause decreases in hemoglobin and hematocrit. In placebo controlled monotherapy trials, mean hemoglobin values declined by 2% to 4% in patients treated with pioglitazone compared with a mean change in hemoglobin of -1% to +1% in placebo-treated patients. These changes primarily occurred within the first 4 to 12 weeks of therapy and remained relatively constant thereafter. These changes may be related to increased plasma volume associated with pioglitazone therapy and are not likely to be associated with any clinically significant hematologic effects.
During protocol-specified measurement of serum creatine phosphokinase (CPK) in pioglitazone clinical trials, an isolated elevation in CPK to greater than 10 times the upper limit of the reference range was noted in 9 (0.2%) patients treated with pioglitazone (values of 2150 to 11400 IU/L) and in no comparator-treated patient. Six of these nine patients continued to receive pioglitazone, two patients were noted to have the CPK elevation on the last day of dosing and one patient discontinued pioglitazone due to the elevation. These elevations resolved without any apparent clinical sequelae. The relationship of these events to pioglitazone therapy is unknown.
The following adverse reactions have been identified during the postmarketing use of alogliptin outside the United States. 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.
Hypersensitivity reactions including anaphylaxis, angioedema, rash, urticaria, and severe cutaneous adverse reactions including Stevens-Johnson syndrome; hepatic enzyme elevations; fulminant hepatic failure; and acute pancreatitis.
The following adverse reactions have been identified during the postmarketing use of pioglitazone. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Fatal and non-fatal hepatic failure [see WARNINGS AND PRECAUTIONS].
Postmarketing reports of congestive heart failure have been reported in patients treated with pioglitazone, both with and without previously known heart disease and both with and without concomitant insulin administration.
In postmarketing experience, there have been reports of unusually rapid increases in weight and increases in excess of that generally observed in clinical trials. Patients who experience such increases should be assessed for fluid accumulation and volumerelated events such as excessive edema and congestive heart failure [see BOXED WARNING and WARNINGS AND PRECAUTIONS].
