INDICATIONS AND USAGE

Pioglitazone Tablets, USP are a thiazolidinedione and an agonist for peroxisome proliferator- activated receptor (PPAR) gamma indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus in multiple clinical settings. (1.1, 14)

Important Limitation of Use:

Not for treatment of type 1 diabetes or diabetic ketoacidosis. (1.2)

DOSAGE AND ADMINISTRATION

Initiate Pioglitazone Tablets, USP at 15 mg or 30 mg once daily. Limit initial dose to 15 mg once daily in patients with NYHA Class I or II heart failure. (2.1)
If there is inadequate glycemic control, the dose can be increased in 15 mg increments up to a maximum of 45 mg once daily. (2.1)
The maximum recommended dose of Pioglitazone Tablets, USP is 15 mg once daily in patients taking strong CYP2C8 inhibitors (e.g., gemfibrozil). (2.3, 7.1)
Obtain liver tests before starting Pioglitazone Tablets, USP. If abnormal, use caution when treating with Pioglitazone Tablets, USP, investigate the probable cause, treat (if possible) and follow appropriately. Monitoring liver tests while on Pioglitazone Tablets, USP is not recommended in patients without liver disease. (5.3)

DOSAGE FORMS AND STRENGTHS

Tablets: 15 mg, 30 mg, and 45 mg (3)

CONTRAINDICATIONS

Do not initiate Pioglitazone Tablets, USP in patients with established NYHA Class III or IV heart failure. (4)
Do not use in patients with a history of a serious hypersensitivity reaction to Pioglitazone Tablets, USP or its ingredients. (4)

WARNINGS AND PRECAUTIONS

Congestive heart failure: Fluid retention may occur and can exacerbate or lead to congestive heart failure. Combination use with insulin and use in congestive heart failure NYHA Class I and II may increase risk. Monitor patients for signs and symptoms. (5.1)
Edema: Dose-related edema may occur. (5.2)
Hepatic effects: Postmarketing reports of hepatic failure, sometimes fatal. Causality cannot be excluded. If liver injury is detected, promptly interrupt Pioglitazone Tablets, USP and assess patient for probable cause, then treat cause if possible, to resolution or stabilization. Do not restart Pioglitazone Tablets, USP if liver injury is confirmed and no alternate etiology can be found. (5.3)
Fractures: Increased incidence in female patients. Apply current standards of care for assessing and maintaining bone health. (5.4)
Bladder cancer: Preclinical and clinical trial data, and results from an observational study suggest an increased risk of bladder cancer in pioglitazone users. The observational data further suggest that the risk increases with duration of use. Do not use in patients with active bladder cancer. Use caution when using in patients with a prior history of bladder cancer (5.5)
Hypoglycemia: When used with insulin or an insulin secretagogue, a lower dose of the insulin or insulin secretagogue may be needed to reduce the risk of hypoglycemia. (5.6)
Macular edema: Postmarketing reports. Recommend regular eye exams in all patients with diabetes according to current standards of care with prompt evaluation for acute visual changes. (5.7)
Macrovascular outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Pioglitazone Tablets, USP or any other anti-diabetic drug. (5.9)

FULL PRESCRIBING INFORMATION

WARNING: CONGESTIVE HEART FAILURE

Thiazolidinediones, including Pioglitazone Tablets, USP, cause or exacerbate congestive heart failure in some patients [see Warnings and Precautions (5.1)].
After initiation of Pioglitazone Tablets, USP, and after dose increases, monitor patients carefully for signs and symptoms of heart failure (e.g., excessive, rapid weight gain, dyspnea, and/or edema). If heart failure develops, it should be managed according to current standards of care and discontinuation or dose reduction of Pioglitazone Tablets, USP must be considered.
Pioglitazone Tablets, USP are not recommended in patients with symptomatic heart failure.
Initiation of Pioglitazone Tablets, USP in patients with established New York Heart Association (NYHA) Class III or IV heart failure is contraindicated [see Contraindications (4) and Warnings and Precautions (5.1)].

1 INDICATIONS AND USAGE

1.1 Monotherapy and Combination Therapy

Pioglitazone Tablets, USP are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus in multiple clinical settings [see Clinical Studies (14)].

1.2 Important Limitation of Use

Pioglitazone Tablets, USP exert their antihyperglycemic effect only in the presence of endogenous insulin. Pioglitazone Tablets, USP should not be used to treat type 1 diabetes or diabetic ketoacidosis, as it would not be effective in these settings.

Use caution in patients with liver disease [see Warnings and Precautions (5.3)].

2 DOSAGE AND ADMINISTRATION

2.1 Recommendations for all patients

Pioglitazone Tablets, USP should be taken once daily and can be taken without regard to meals.

The recommended starting dose for patients without congestive heart failure is 15 mg or 30 mg once daily.

The recommended starting dose for patients with congestive heart failure (NYHA Class I or II) is 15 mg once daily.

The dose can be titrated in increments of 15 mg up to a maximum of 45 mg once daily based on glycemic response as determined by HbA1c.

After initiation of Pioglitazone Tablets, USP or with dose increase, monitor patients carefully for adverse reactions related to fluid retention such as weight gain, edema, and signs and symptoms of congestive heart failure [see Boxed Warning and Warnings and Precautions (5.2)].

Liver tests (serum alanine and aspartate aminotransferases, alkaline phosphatase, and total bilirubin) should be obtained prior to initiating Pioglitazone Tablets, USP. Routine periodic monitoring of liver tests during treatment with Pioglitazone Tablets, USP is not recommended in patients without liver disease. Patients who have liver test abnormalities prior to initiation of Pioglitazone Tablets, USP or who are found to have abnormal liver tests while taking Pioglitazone Tablets, USP should be managed as described under Warnings and Precautions [see Warnings and Precautions (5.3) and Clinical Pharmacology (12.3)].

2.2 Concomitant use with an insulin secretagogue or insulin

If hypoglycemia occurs in a patient co-administered Pioglitazone Tablets, USP and an insulin secretagogue (e.g., sulfonylurea), the dose of the insulin secretagogue should be reduced.

If hypoglycemia occurs in a patient co-administered Pioglitazone Tablets, USP and insulin, the dose of insulin should be decreased by 10% to 25%. Further adjustments to the insulin dose should be individualized based on glycemic response.

2.3 Coadministration with strong CYP2C8 inhibitors

Coadministration of Pioglitazone Tablets, USP and gemfibrozil, a strong CYP2C8 inhibitor, increases pioglitazone exposure approximately 3-fold. Therefore, the maximum recommended dose of Pioglitazone Tablets, USP is 15 mg daily when used in combination with gemfibrozil or other strong CYP2C8 inhibitors [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)].

3 DOSAGE FORMS AND STRENGTHS

Round tablet contains pioglitazone as follows:

15 mg: White to off-white, debossed with "PGZ" on one side and "15" on the other side
30 mg: White to off-white, debossed with "PGZ" on one side and "30" on the other side
45 mg: White to off-white, debossed with "PGZ" on one side and "45" on the other side

4 CONTRAINDICATIONS

Do not initiate in patients with NYHA Class III or IV heart failure [see Boxed Warning].

Do not use in patients with a history of a serious hypersensitivity reaction to Pioglitazone Tablets, USP or any of its ingredients.

5 WARNINGS AND PRECAUTIONS

5.1 Congestive Heart Failure

Pioglitazone Tablets, USP, like other thiazolidinediones, can cause dose-related fluid retention when used alone or in combination with other antidiabetic medications and is most common when Pioglitazone Tablets, USP are used in combination with insulin. Fluid retention may lead to or exacerbate congestive heart failure. Patients should be observed for signs and symptoms of congestive heart failure. If congestive heart failure develops, it should be managed according to current standards of care and discontinuation or dose reduction of Pioglitazone Tablets, USP must be considered [see Boxed Warning, Contraindications (4), and Adverse Reactions (6.1)].

5.2 Edema

In controlled clinical trials, edema was reported more frequently in patients treated with Pioglitazone Tablets, USP than in placebo-treated patients and is dose-related [see Adverse Reactions (6.1)]. In postmarketing experience, reports of new onset or worsening edema have been received.

Pioglitazone Tablets, USP should be used with caution in patients with edema. Because thiazolidinediones, including Pioglitazone Tablets, USP, can cause fluid retention, which can exacerbate or lead to congestive heart failure, Pioglitazone Tablets, USP should be used with caution in patients at risk for congestive heart failure. Patients treated with Pioglitazone Tablets, USP should be monitored for signs and symptoms of congestive heart failure [see Boxed Warning, Warnings and Precautions (5.1) and Patient Counseling Information (17.1)].

5.3 Hepatic Effects

There have been postmarketing reports of fatal and non-fatal hepatic failure in patients taking Pioglitazone Tablets, USP, although the reports contain insufficient information necessary to establish the probable cause. There has been no evidence of drug-induced hepatotoxicity in the Pioglitazone Tablets, USP controlled clinical trial database to date [see Adverse Reactions (6.1)].

Patients with type 2 diabetes may have fatty liver disease or cardiac disease with episodic congestive heart failure, both of which may cause liver test abnormalities, and they may also have other forms of liver disease, many of which can be treated or managed. Therefore, obtaining a liver test panel (serum alanine aminotransferase [ALT], aspartate aminotransferase [AST], alkaline phosphatase, and total bilirubin) and assessing the patient is recommended before initiating Pioglitazone Tablets, USP therapy. In patients with abnormal liver tests, Pioglitazone Tablets, USP should be initiated with caution.

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 abnormal liver tests (ALT greater than 3 times the upper limit of the reference range), Pioglitazone Tablets, USP treatment should be interrupted and investigation done to establish the probable cause. Pioglitazone Tablets, USP should not be restarted in these patients without another explanation for the liver test abnormalities.

Patients who have serum ALT greater than three times the reference range with serum total bilirubin greater than two times the reference range without alternative etiologies are at risk for severe drug-induced liver injury, and should not be restarted on Pioglitazone Tablets, USP. For patients with lesser elevations of serum ALT or bilirubin and with an alternate probable cause, treatment with Pioglitazone Tablets, USP can be used with caution.

5.4 Fractures

In PROactive (the Prospective Pioglitazone Clinical Trial in Macrovascular Events), 5238 patients with type 2 diabetes and a history of macrovascular disease were randomized to Pioglitazone Tablets, USP (N=2605), force-titrated up to 45 mg daily or placebo (N=2633) in addition to standard of care. During a mean follow-up of 34.5 months, the incidence of bone fracture in females was 5.1% (44/870) for Pioglitazone Tablets, USP versus 2.5% (23/905) for placebo. This difference was noted after the first year of treatment and persisted during the course of the study. The majority of fractures observed in female patients were nonvertebral fractures including lower limb and distal upper limb. No increase in the incidence of fracture was observed in men treated with Pioglitazone Tablets, USP (1.7%) versus placebo (2.1%). The risk of fracture should be considered in the care of patients, especially female patients, treated with Pioglitazone Tablets, USP and attention should be given to assessing and maintaining bone health according to current standards of care.

5.5 Urinary Bladder Tumors

Tumors were observed in the urinary bladder of male rats in the two-year carcinogenicity study [see Nonclinical Toxicology (13.1)]. In two 3-year trials in which Pioglitazone Tablets, USP were compared to placebo or glyburide, there were 16/3656 (0.44%) reports of bladder cancer in patients taking Pioglitazone Tablets, USP compared to 5/3679 (0.14%) in patients not taking Pioglitazone Tablets, USP. 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 Tablets, USP and two (0.05%) cases on placebo.

A five-year interim report of an ongoing 10-year observational cohort study found a non-significant increase in the risk of bladder cancer in subjects ever exposed to Pioglitazone Tablets, USP, compared to subjects never exposed to Pioglitazone Tablets, USP (HR 1.2 [95% CI 0.9-1.5]). Compared to never exposure, a duration of Pioglitazone Tablets, USP therapy longer than 12 months was associated with an increase in risk (HR 1.4 [95% CI 0.9-2.1]), which reached statistical significance after more than 24 months of Pioglitazone Tablets, USP use (HR 1.4 [95% CI 1.03-2.0]). Interim results from this study suggest that taking Pioglitazone Tablets, USP longer than 12 months increased the relative risk of developing bladder cancer in any given year by 40% which equates to an absolute increase of 3 cases in 10,000 (from approximately 7 in 10,000 [without Pioglitazone Tablets, USP] to approximately 10 in 10,000 [with Pioglitazone Tablets, USP]).

There are insufficient data to determine whether pioglitazone is a tumor promoter for urinary bladder tumors. Consequently, Pioglitazone Tablets, USP should not be used in patients with active bladder cancer and the benefits of glycemic control versus unknown risks for cancer recurrence with Pioglitazone Tablets, USP should be considered in patients with a prior history of bladder cancer.

5.6 Hypoglycemia

Patients receiving Pioglitazone Tablets, USP in combination with insulin or other anti-diabetic medications (particularly insulin secretagogues such as sulfonylureas) may be at risk for hypoglycemia. A reduction in the dose of the concomitant anti-diabetic medication may be necessary to reduce the risk of hypoglycemia [see Dosage and Administration (2.2)].

5.7 Macular Edema

Macular edema has been reported in postmarketing experience in diabetic patients who were taking Pioglitazone Tablets, USP or another thiazolidinedione. Some patients presented with blurred vision or decreased visual acuity, but others were diagnosed on routine ophthalmologic examination.

Most patients had peripheral edema at the time macular edema was diagnosed. Some patients had improvement in their macular edema after discontinuation of the thiazolidinedione.

Patients with diabetes should have regular eye exams by an ophthalmologist according to current standards of care. Patients with diabetes who report any visual symptoms should be promptly referred to an ophthalmologist, regardless of the patient's underlying medications or other physical findings [see Adverse Reactions (6.1)].

5.8 Ovulation

Therapy with Pioglitazone Tablets, USP, like other thiazolidinediones, may result in ovulation in some premenopausal anovulatory women. As a result, these patients may be at an increased risk for pregnancy while taking Pioglitazone Tablets, USP [see Use in Specific Populations (8.1)]. This effect has not been investigated in clinical trials, so the frequency of this occurrence is not known. Adequate contraception in all premenopausal women treated with Pioglitazone Tablets, USP is recommended.

5.9 Macrovascular Outcomes

There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Pioglitazone Tablets, USP or any other anti-diabetic drug.

6 ADVERSE REACTIONS

The following serious adverse reactions are discussed elsewhere in the labeling:

Congestive heart failure [see Boxed Warning and Warnings and Precautions (5.1)]
Edema [see Warnings and Precautions (5.2)]
Fractures [see Warnings and Precautions (5.4)]

6.1 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 practice.

Over 8500 patients with type 2 diabetes have been treated with Pioglitazone Tablets, USP in randomized, double-blind, controlled clinical trials, including 2605 patients with type 2 diabetes and macrovascular disease treated with Pioglitazone Tablets, USP in the PROactive clinical trial. In these trials, over 6000 patients have been treated with Pioglitazone Tablets, USP for 6 months or longer, over 4500 patients have been treated with Pioglitazone Tablets, USP for one year or longer, and over 3000 patients have been treated with Pioglitazone Tablets, USP for at least 2 years.

In six pooled 16 to 26-week placebo-controlled monotherapy and 16 to 24-week add-on combination therapy trials, the incidence of withdrawals due to adverse events was 4.5% for patients treated with Pioglitazone Tablets, USP and 5.8% for comparator-treated patients. The most common adverse events leading to withdrawal were related to inadequate glycemic control, although the incidence of these events was lower (1.5%) with Pioglitazone Tablets, USP than with placebo (3.0%).

In the PROactive trial, the incidence of withdrawals due to adverse events was 9.0% for patients treated with Pioglitazone Tablets, USP and 7.7% for placebo-treated patients. Congestive heart failure was the most common serious adverse event leading to withdrawal occurring in 1.3% of patients treated with Pioglitazone Tablets, USP and 0.6% of patients treated with placebo.

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 Tablets, USP is provided in Table 1. Terms that are reported represent those that occurred at an incidence of > 5% and more commonly in patients treated with Pioglitazone Tablets, USP than in patients who received placebo. None of these adverse events were related to Pioglitazone Tablets, USP dose.

Cardiovascular Safety:

In the PROactive trial, 5238 patients with type 2 diabetes and a history of macrovascular disease were randomized to Pioglitazone Tablets, USP (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 HbA1c 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 Tablets, USP 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 Tablets, USP 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 Tablets, USP 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 Tablets, USP. The number of first occurrences and total individual events contributing to the primary composite endpoint is shown in Table 9.

Weight Gain:

Dose-related weight gain occurs when Pioglitazone Tablets, USP are used alone or in combination with other anti-diabetic medications. The mechanism of weight gain is unclear but probably involves a combination of fluid retention and fat accumulation.

Tables 10 and 11 summarize the changes in body weight with Pioglitazone Tablets, USP and placebo in the 16 to 26-week randomized, double-blind monotherapy and 16 to 24-week combination add-on therapy trials and in the PROactive trial.

Edema:

Edema induced from taking Pioglitazone Tablets, USP is reversible when Pioglitazone Tablets, USP are discontinued. The edema usually does not require hospitalization unless there is coexisting congestive heart failure. A summary of the frequency and types of edema adverse events occurring in clinical investigations of Pioglitazone Tablets, USP is provided in Table 12.

Hepatic Effects:

There has been no evidence of Pioglitazone Tablets, USP-induced hepatotoxicity in the Pioglitazone Tablets, USP controlled clinical trial database to date. One randomized, double-blind, 3-year trial comparing Pioglitazone Tablets, USP 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 Tablets, USP 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 Tablets, USP in the Pioglitazone Tablets, USP 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.

Hypoglycemia:

In the Pioglitazone Tablets, USP 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 Tablets, USP 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 Pioglitazone Tablets, USP 15 mg, 15.4% with Pioglitazone Tablets, USP 30 mg, and 4.8% with placebo.

The incidence of reported hypoglycemia was higher with Pioglitazone Tablets, USP 45 mg compared to Pioglitazone Tablets, USP 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 Tablets, USP 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 Tablets, USP 45 mg in combination with sulfonylurea (n=2) or Pioglitazone Tablets, USP 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 (13.1)]. In two 3-year trials in which Pioglitazone Tablets, USP were compared to placebo or glyburide, there were 16/3656 (0.44%) reports of bladder cancer in patients taking Pioglitazone Tablets, USP compared to 5/3679 (0.14%) in patients not taking Pioglitazone Tablets, USP. 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 Tablets, USP and two (0.05%) cases on placebo. There are too few events of bladder cancer to establish causality.

6.2 Laboratory Abnormalities

Hematologic Effects:

Pioglitazone Tablets, USP 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 Tablets, USP 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 Tablets, USP therapy and are not likely to be associated with any clinically significant hematologic effects.

Creatine Phosphokinase:

During protocol-specified measurement of serum creatine phosphokinase (CPK) in Pioglitazone Tablets, USP 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 Tablets, USP (values of 2150 to 11400 IU/L) and in no comparator-treated patients. Six of these nine patients continued to receive Pioglitazone Tablets, USP, two patients were noted to have the CPK elevation on the last day of dosing and one patient discontinued Pioglitazone Tablets, USP due to the elevation. These elevations resolved without any apparent clinical sequelae. The relationship of these events to Pioglitazone Tablets, USP therapy is unknown.

6.3 Postmarketing Experience

The following adverse reactions have been identified during post-approval use of Pioglitazone Tablets, USP. 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.

New onset or worsening diabetic macular edema with decreased visual acuity [see Warnings and Precautions (5.2)].
Fatal and non-fatal hepatic failure [see Warnings and Precautions (5.3)].

Postmarketing reports of congestive heart failure have been reported in patients treated with Pioglitazone Tablets, USP, 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 volume-related events such as excessive edema and congestive heart failure [see Boxed Warning and Warnings and Precautions (5.1)].

7 DRUG INTERACTIONS

7.1 Strong CYP2C8 Inhibitors

An inhibitor of CYP2C8 (e.g., gemfibrozil) significantly increases the exposure (area under the serum concentration-time curve or AUC) and half-life of pioglitazone. Therefore, the maximum recommended dose of Pioglitazone Tablets, USP is 15 mg daily if used in combination with gemfibrozil or other strong CYP2C8 inhibitors [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].

7.2 CYP2C8 Inducers

An inducer of CYP2C8 (e.g., rifampin) may significantly decrease the exposure (AUC) of pioglitazone. Therefore, if an inducer of CYP2C8 is started or stopped during treatment with Pioglitazone Tablets, USP, changes in diabetes treatment may be needed based on clinical response without exceeding the maximum recommended daily dose of 45 mg for Pioglitazone Tablets, USP [see Clinical Pharmacology (12.3)].

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C.

There are no adequate and well-controlled studies of Pioglitazone Tablets, USP in pregnant women. Animal studies show increased rates of post-implantation loss, delayed development, reduced fetal weights, and delayed parturition at doses 10 to 40 times the maximum recommended human dose. Pioglitazone Tablets, USP should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Clinical Considerations:

Abnormal blood glucose concentrations during pregnancy are associated with a higher incidence of congenital anomalies, as well as increased neonatal morbidity and mortality. Most experts recommend the use of insulin during pregnancy to maintain blood glucose concentrations as close to normal as possible for patients with diabetes.

Animal Data:

In animal reproductive studies, pregnant rats and rabbits received pioglitazone at doses up to approximately 17 (rat) and 40 (rabbit) times the maximum recommended human oral dose (MRHD) based on body surface area (mg/m2); no teratogenicity was observed [see Nonclinical Toxicology (13.3)]. Increases in embryotoxicity (increased postimplantation losses, delayed development, reduced fetal weights, and delayed parturition) occurred in rats that received oral doses approximately 10 or more times the MRHD (mg/m2 basis). No functional or behavioral toxicity was observed in rat offspring. When pregnant rats received pioglitazone during late gestation and lactation, delayed postnatal development, attributed to decreased body weight, occurred in rat offspring at oral maternal doses approximately 2 or more times the MRHD (mg/m2 basis). In rabbits, embryotoxicity occurred at oral doses approximately 40 times the MRHD (mg/m2 basis).

8.3 Nursing Mothers

It is not known whether Pioglitazone Tablets, USP are secreted in human milk. Pioglitazone is secreted in the milk of lactating rats. Because many drugs are excreted in human milk, and because of the potential for Pioglitazone Tablets, USP to cause serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or discontinue Pioglitazone Tablets, USP, taking into account the importance of Pioglitazone Tablets, USP to the mother.

8.4 Pediatric Use

Safety and effectiveness of Pioglitazone Tablets, USP in pediatric patients have not been established.

Use in pediatric patients is not recommended for the treatment of diabetes due to lack of long-term safety data. Risks including fractures and other adverse effects associated with Pioglitazone Tablets, USP have not been determined in this population [see Warnings and Precautions (5.4)].

8.5 Geriatric Use

A total of 92 patients (15.2%) treated with Pioglitazone Tablets, USP in the three pooled 16 to 26-week double-blind, placebo-controlled, monotherapy, trials were ≥ 65 years old and 2 patients (0.3%) were ≥75 years old. In the two pooled 16 to 24-week add-on to sulfonylurea trials, 201 patients (18.7%) treated with Pioglitazone Tablets, USP were ≥ 65 years old and 19 (1.8%) were ≥ 75 years old. In the two pooled 16 to 24 week add-on to metformin trials, 155 patients (15.5%) treated with Pioglitazone Tablets, USP were ≥ 65 years old and 19 (1.9%) were ≥ 75 years old. In the two pooled 16 to 24 week add-on to insulin trials, 272 patients (25.4%) treated with Pioglitazone Tablets, USP were ≥ 65 years old and 22 (2.1%) were ≥ 75 years old.

In PROactive, 1068 patients (41.0%) treated with Pioglitazone Tablets, USP were ≥ 65 years old and 42 (1.6%) were ≥ 75 years old.

In pharmacokinetic studies with pioglitazone, no significant differences were observed in pharmacokinetic parameters between elderly and younger patients. These clinical experiences have not identified differences in effectiveness and safety between the elderly (≥ 65 years) and younger patients although small sample sizes for patients ≥ 75 years old limit conclusions [see Clinical Pharmacology (12.3)].

10 OVERDOSAGE

During controlled clinical trials, one case of overdose with Pioglitazone Tablets, USP was reported. A male patient took 120 mg per day for four days, then 180 mg per day for seven days. The patient denied any clinical symptoms during this period.

In the event of overdosage, appropriate supportive treatment should be initiated according to the patient's clinical signs and symptoms.

11 DESCRIPTION

Pioglitazone Tablets, USP are an oral antidiabetic medication.

Pioglitazone [(±)-5-[[4-[2-(5-ethyl-2-pyridinyl) ethoxy] phenyl] methyl]-2,4-] thiazolidinedione monohydrochloride contains one asymmetric carbon, and the compound is synthesized and used as the racemic mixture. The two enantiomers of pioglitazone interconvert in vivo. No differences were found in the pharmacologic activity between the two enantiomers. The structural formula is as shown:

Chemical Structure-Pioglitazone Hydrochloride

Pioglitazone hydrochloride, USP is an odorless white crystalline powder that has a molecular formula of C19H20N2O3S•HCl and a molecular weight of 392.90 daltons. It is soluble in N,N-dimethylformamide, slightly soluble in anhydrous ethanol, very slightly soluble in acetone and acetonitrile, practically insoluble in water, and insoluble in ether.

Pioglitazone Tablets, USP are available as tablets for oral administration containing 15 mg, 30 mg, or 45 mg of pioglitazone (as the base) formulated with the following excipients: lactose monohydrate NF, hydroxypropyl - cellulose NF, carboxymethylcellulose calcium NF, and magnesium stearate NF.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Pioglitazone Tablets, USP are a thiazolidinedione that depends on the presence of insulin for its mechanism of action. Pioglitazone Tablets, USP decrease insulin resistance in the periphery and in the liver resulting in increased insulin-dependent glucose disposal and decreased hepatic glucose output. Pioglitazone is not an insulin secretagogue. Pioglitazone is an agonist for peroxisome proliferator-activated receptor-gamma (PPARγ). PPAR receptors are found in tissues important for insulin action such as adipose tissue, skeletal muscle, and liver. Activation of PPARγ nuclear receptors modulates the transcription of a number of insulin responsive genes involved in the control of glucose and lipid metabolism.

In animal models of diabetes, pioglitazone reduces the hyperglycemia, hyperinsulinemia, and hypertriglyceridemia characteristic of insulin-resistant states such as type 2 diabetes. The metabolic changes produced by pioglitazone result in increased responsiveness of insulin-dependent tissues and are observed in numerous animal models of insulin resistance.

Because pioglitazone enhances the effects of circulating insulin (by decreasing insulin resistance), it does not lower blood glucose in animal models that lack endogenous insulin.

12.2 Pharmacodynamics

Clinical studies demonstrate that Pioglitazone Tablets, USP improve insulin sensitivity in insulin-resistant patients. Pioglitazone Tablets, USP enhance cellular responsiveness to insulin, increase insulin-dependent glucose disposal and improve hepatic sensitivity to insulin. In patients with type 2 diabetes, the decreased insulin resistance produced by Pioglitazone Tablets, USP results in lower plasma glucose concentrations, lower plasma insulin concentrations, and lower HbA1c values. In controlled clinical trials, Pioglitazone Tablets, USP had an additive effect on glycemic control when used in combination with a sulfonylurea, metformin, or insulin [see Clinical Studies (14.2)].

Patients with lipid abnormalities were included in clinical trials with Pioglitazone Tablets, USP. Overall, patients treated with Pioglitazone Tablets, USP had mean decreases in serum triglycerides, mean increases in HDL cholesterol, and no consistent mean changes in LDL and total cholesterol. There is no conclusive evidence of macrovascular benefit with Pioglitazone Tablets, USP or any other antidiabetic medication [see Warnings and Precautions (5.9) and Adverse Reactions (6.1)].

In a 26-week, placebo-controlled, dose-ranging monotherapy study, mean serum triglycerides decreased in the 15 mg, 30 mg, and 45 mg Pioglitazone Tablets, USP dose groups compared to a mean increase in the placebo group. Mean HDL cholesterol increased to a greater extent in patients treated with Pioglitazone Tablets, USP than in the placebo-treated patients. There were no consistent differences for LDL and total cholesterol in patients treated with Pioglitazone Tablets, USP compared to placebo (Table 14).

In the two other monotherapy studies (16 weeks and 24 weeks) and in combination therapy studies with sulfonylurea (16 weeks and 24 weeks), metformin (16 weeks and 24 weeks ) or insulin (16 weeks and 24 weeks), the results were generally consistent with the data above.

12.3 Pharmacokinetics

Following once daily administration of Pioglitazone Tablets, USP, steady-state serum concentrations of both pioglitazone and its major active metabolites, M-III (keto derivative of pioglitazone) and M-IV (hydroxyl derivative of pioglitazone), are achieved within 7 days. At steady-state, M-III and M-IV reach serum concentrations equal to or greater than that of pioglitazone. At steady-state, in both healthy volunteers and patients with type 2 diabetes, pioglitazone comprises approximately 30% to 50% of the peak total pioglitazone serum concentrations (pioglitazone plus active metabolites) and 20% to 25% of the total AUC. Maximum serum concentration (Cmax), AUC, and trough serum concentrations (Cmin) for pioglitazone and M-III and M-IV, increased proportionally with administered doses of 15 mg and 30 mg per day.

Absorption:

Following oral administration of pioglitazone hydrochloride, peak concentrations of pioglitazone were observed within 2 hours. Food slightly delays the time to peak serum concentration (Tmax) to 3 to 4 hours, but does not alter the extent of absorption (AUC).

Distribution:

The mean apparent volume of distribution (Vd/F) of pioglitazone following single-dose administration is 0.63 ± 0.41 (mean ± SD) L/kg of body weight. Pioglitazone is extensively protein bound (> 99%) in human serum, principally to serum albumin. Pioglitazone also binds to other serum proteins, but with lower affinity. M-III and M-IV are also extensively bound (> 98%) to serum albumin.

Metabolism:

Pioglitazone is extensively metabolized by hydroxylation and oxidation; the metabolites also partly convert to glucuronide or sulfate conjugates. Metabolites M-III and M-IV are the major circulating active metabolites in humans.

In vitro data demonstrate that multiple CYP isoforms are involved in the metabolism of pioglitazone. The cytochrome P450 isoforms involved are CYP2C8 and, to a lesser degree, CYP3A4 with additional contributions from a variety of other isoforms including the mainly extrahepatic CYP1A1. In vivo study of pioglitazone in combination with gemfibrozil, a strong CYP2C8 inhibitor showed that pioglitazone is a CYP2C8 substrate [see Dosage and Administration (2.3) and Drug Interactions (7)]. Urinary 6β-hydroxycortisol/cortisol ratios measured in patients treated with Pioglitazone Tablets, USP showed that pioglitazone is not a strong CYP3A4 enzyme inducer.

Excretion and Elimination:

Following oral administration, approximately 15% to 30% of the pioglitazone dose is recovered in the urine. Renal elimination of pioglitazone is negligible, and the drug is excreted primarily as metabolites and their conjugates. It is presumed that most of the oral dose is excreted into the bile either unchanged or as metabolites and eliminated in the feces.

The mean serum half-life of pioglitazone and its metabolites (M-III and M-IV) range from 3 to 7 hours and 16 to 24 hours, respectively. Pioglitazone has an apparent clearance, CL/F, calculated to be 5 to 7 L/hr.

Renal Impairment:

The serum elimination half-life of pioglitazone, M-III, and M-IV remains unchanged in patients with moderate (creatinine clearance 30 to 50 mL/min) and severe (creatinine clearance < 30 mL/min) renal impairment when compared to subjects with normal renal function. Therefore, no dose adjustment in patients with renal impairment is required.

Hepatic Impairment:

Compared with healthy controls, subjects with impaired hepatic function (Child-Turcotte-Pugh Grade B/C) have an approximate 45% reduction in pioglitazone and total pioglitazone (pioglitazone, M-III and M-IV) mean peak concentrations but no change in the mean AUC values. Therefore, no dose adjustment in patients with hepatic impairment is required.

There are postmarketing reports of liver failure with Pioglitazone Tablets, USP and clinical trials have generally excluded patients with serum ALT > 2.5x the upper limit of the reference range. Use caution in patients with liver disease [see Warnings and Precautions (5.3)].

Geriatric Patients:

In healthy elderly subjects, peak serum concentrations of pioglitazone are not significantly different, but AUC values are approximately 21% higher than those achieved in younger subjects. The mean terminal half-life values of pioglitazone were also longer in elderly subjects (about 10 hours) as compared to younger subjects (about 7 hours). These changes were not of a magnitude that would be considered clinically relevant.

Pediatric Patients:

Safety and efficacy of pioglitazone in pediatric patients have not been established. Pioglitazone Tablets, USP are not recommended for use in pediatric patients [see Use in Specific Populations (8.4)].

Gender:

The mean Cmax and AUC values of pioglitazone were increased 20% to 60% in women compared to men. In controlled clinical trials, HbA1c decreases from baseline were generally greater for females than for males (average mean difference in HbA1c 0.5%). Because therapy should be individualized for each patient to achieve glycemic control, no dose adjustment is recommended based on gender alone.

Ethnicity:

Pharmacokinetic data among various ethnic groups are not available.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

A two-year carcinogenicity study was conducted in male and female rats at oral doses up to 63 mg/kg (approximately 14 times the maximum recommended human oral dose of 45 mg based on mg/m2). Drug-induced tumors were not observed in any organ except for the urinary bladder. Benign and/or malignant transitional cell neoplasms were observed in male rats at 4 mg/kg/day and above (approximately equal to the maximum recommended human oral dose based on mg/m2). A two-year carcinogenicity study was conducted in male and female mice at oral doses up to 100 mg/kg/day (approximately 11 times the maximum recommended human oral dose based on mg/m2). No drug-induced tumors were observed in any organ.

Pioglitazone hydrochloride was not mutagenic in a battery of genetic toxicology studies, including the Ames bacterial assay, a mammalian cell forward gene mutation assay (CHO/HPRT and AS52/XPRT), an in vitro cytogenetics assay using CHL cells, an unscheduled DNA synthesis assay, and an in vivo micronucleus assay.

No adverse effects upon fertility were observed in male and female rats at oral doses up to 40 mg/kg pioglitazone hydrochloride daily prior to and throughout mating and gestation (approximately 9 times the maximum recommended human oral dose based on mg/m2).

13.2 Animal Toxicology and/or Pharmacology

Heart enlargement has been observed in mice (100 mg/kg), rats (4 mg/kg and above) and dogs (3 mg/kg) treated orally with pioglitazone hydrochloride (approximately 11, 1, and 2 times the maximum recommended human oral dose for mice, rats, and dogs, respectively, based on mg/m2). In a one-year rat study, drug-related early death due to apparent heart dysfunction occurred at an oral dose of 160 mg/kg/day (approximately 35 times the maximum recommended human oral dose based on mg/m2). Heart enlargement was seen in a 13-week study in monkeys at oral doses of 8.9 mg/kg and above (approximately 4 times the maximum recommended human oral dose based on mg/m2), but not in a 52-week study at oral doses up to 32 mg/kg (approximately 13 times the maximum recommended human oral dose based on mg/m2).

13.3 Reproductive and Developmental Toxicology

Pioglitazone was not teratogenic in rats at oral doses up to 80 mg/kg or in rabbits given up to 160 mg/kg during organogenesis (approximately 17 and 40 times the maximum recommended human oral dose based on mg/m2, respectively). Delayed parturition and embryotoxicity (as evidenced by increased postimplantation losses, delayed development and reduced fetal weights) were observed in rats at oral doses of 40 mg/kg/day and above (approximately 10 times the maximum recommended human oral dose based on mg/m2). No functional or behavioral toxicity was observed in offspring of rats. In rabbits, embryotoxicity was observed at an oral dose of 160 mg/kg (approximately 40 times the maximum recommended human oral dose based on mg/m2). Delayed postnatal development, attributed to decreased body weight, was observed in offspring of rats at oral doses of 10 mg/kg and above during late gestation and lactation periods (approximately 2 times the maximum recommended human oral dose based on mg/m2).

14 CLINICAL STUDIES

14.1 Monotherapy

Three randomized, double-blind, placebo-controlled trials with durations from 16 to 26 weeks were conducted to evaluate the use of Pioglitazone Tablets, USP as monotherapy in patients with type 2 diabetes. These trials examined Pioglitazone Tablets, USP at doses up to 45 mg or placebo once daily in a total of 865 patients.

In a 26-week dose-ranging monotherapy trial, 408 patients with type 2 diabetes were randomized to receive 7.5 mg, 15 mg, 30 mg, or 45 mg of Pioglitazone Tablets, USP, or placebo once daily. Therapy with any previous antidiabetic agent was discontinued 8 weeks prior to the double-blind period. Treatment with 15 mg, 30 mg, and 45 mg of Pioglitazone Tablets, USP produced statistically significant improvements in HbA1c and fasting plasma glucose (FPG) at endpoint compared to placebo (see Figure 1 and Table 17).

Figure 1 shows the time course for changes in HbA1c in this 26-week study.

In a 24-week placebo-controlled monotherapy trial, 260 patients with type 2 diabetes were randomized to one of two forced-titration Pioglitazone Tablets, USP treatment groups or a mock-titration placebo group. Therapy with any previous antidiabetic agent was discontinued 6 weeks prior to the double-blind period. In one Pioglitazone Tablets, USP treatment group, patients received an initial dose of 7.5 mg once daily. After four weeks, the dose was increased to 15 mg once daily and after another four weeks, the dose was increased to 30 mg once daily for the remainder of the trial (16 weeks). In the second Pioglitazone Tablets, USP treatment group, patients received an initial dose of 15 mg once daily and were titrated to 30 mg once daily and 45 mg once daily in a similar manner. Treatment with Pioglitazone Tablets, USP, as described, produced statistically significant improvements in HbA1c and FPG at endpoint compared to placebo.

14.2 Combination Therapy

Three 16-week, randomized, double-blind, placebo-controlled clinical trials were conducted to evaluate the effects of Pioglitazone Tablets, USP (15 mg and/or 30 mg) on glycemic control in patients with type 2 diabetes who were inadequately controlled (HbA1c ≥ 8%) despite current therapy with a sulfonylurea, metformin, or insulin. In addition, three 24-week randomized, double-blind clinical trials were conducted to evaluate the effects of Pioglitazone Tablets, USP 30 mg vs. Pioglitazone Tablets, USP 45 mg on glycemic control in patients with type 2 diabetes who were inadequately controlled (HbA1c ≥ 8%) despite current therapy with a sulfonylurea, metformin, or insulin. Previous diabetes treatment may have been monotherapy or combination therapy.

Add-on to Sulfonylurea Trials:

Two clinical trials were conducted with Pioglitazone Tablets, USP in combination with a sulfonylurea. Both studies included patients with type 2 diabetes on any dose of a sulfonylurea, either alone or in combination with another antidiabetic agent. All other antidiabetic agents were withdrawn at least 3 weeks prior to starting study treatment.

In the first study, 560 patients were randomized to receive 15 mg or 30 mg of Pioglitazone Tablets, USP or placebo once daily for 16 weeks in addition to their current sulfonylurea regimen. Treatment with Pioglitazone Tablets, USP as add-on to sulfonylurea produced statistically significant improvements in HbA1c and FPG at endpoint compared to placebo add-on to sulfonylurea (Table 20).

Add-on to Insulin Trials:

Two clinical trials were conducted with Pioglitazone Tablets, USP in combination with insulin. Both trials included patients with type 2 diabetes on insulin, either alone or in combination with another antidiabetic agent. All other antidiabetic agents were withdrawn prior to starting study treatment. In the first trial, 566 patients were randomized to receive either 15 mg or 30 mg of Pioglitazone Tablets, USP or placebo once daily for 16 weeks in addition to their insulin regimen. Treatment with Pioglitazone Tablets, USP as add-on to insulin produced statistically significant improvements in HbA1c and FPG at endpoint compared to placebo add-on to insulin (see Table 24). The mean daily insulin dose at baseline in each treatment group was approximately 70 units. The majority of patients (75% overall, 86% treated with placebo, 77% treated with Pioglitazone Tablets, USP 15 mg, and 61% treated with Pioglitazone Tablets, USP 30 mg) had no change in their daily insulin dose from baseline to the final study visit. The mean change from baseline in daily dose of insulin (including patients with no insulin dose modifications) was -3 units in the patients treated with Pioglitazone Tablets, USP 15 mg, -8 units in the patients treated with Pioglitazone Tablets, USP 30 mg, and -1 unit in patients treated with placebo.

In the second trial, 690 patients receiving a median of 60 units per day of insulin were randomized to receive either 30 mg or 45 mg of Pioglitazone Tablets, USP once daily for 24 weeks in addition to their current insulin regimen. The mean reduction from baseline at Week 24 in HbA1c was 1.2% for the 30 mg dose and 1.5% for the 45 mg dose. The mean reduction from baseline at Week 24 in FPG was 32 mg/dL for the 30 mg dose and 46 mg/dL for the 45 mg dose (see Table 25). The mean daily insulin dose at baseline in both treatment groups was approximately 70 units. The majority of patients (55% overall, 58% treated with Pioglitazone Tablets, USP 30 mg, and 52% treated with Pioglitazone Tablets, USP 45 mg) had no change in their daily insulin dose from baseline to the final study visit. The mean change from baseline in daily dose of insulin (including patients with no insulin dose modifications) was -5 units in the patients treated with Pioglitazone Tablets, USP 30 mg and -8 units in the patients treated with Pioglitazone Tablets, USP 45 mg.

The therapeutic effect of Pioglitazone Tablets, USP in combination with insulin was observed in patients regardless of the insulin dose.
