ADVERSE REACTIONS Hypoglycemia: See PRECAUTIONS and OVERDOSAGE sections. PRANDIN has been administered to 2931 individuals during clinical trials. Approximately 1500 of these individuals with type 2 diabetes have been treated for at least 3 months, 1000 for at least 6 months, and 800 for at least 1 year. The majority of these individuals (1228) received PRANDIN in one of five 1-year, active-controlled trials. The comparator drugs in these 1-year trials were oral sulfonylurea drugs (SU) including glyburide and glipizide. Over one year, 13% of PRANDIN patients were discontinued due to adverse events, as were 14% of SU patients. The most common adverse events leading to withdrawal were hyperglycemia, hypoglycemia, and related symptoms (see PRECAUTIONS ). Mild or moderate hypoglycemia occurred in 16% of PRANDIN patients, 20% of glyburide patients, and 19% of glipizide patients. The table below lists common adverse events for PRANDIN patients compared to both placebo (in trials 12 to 24 weeks duration) and to glyburide and glipizide in one year trials. The adverse event profile of PRANDIN was generally comparable to that for sulfonylurea drugs (SU).

The incidence of other selected cardiovascular events (hypertension, abnormal EKG, myocardial infarction, arrhythmias, and palpitations) was1% and not different between PRANDIN and the comparator drugs. The incidence of total serious cardiovascular adverse events, including ischemia, was higher for repaglinide (4%) than for sulfonylurea drugs (3%) in controlled comparator clinical trials. In 1-year controlled trials, PRANDIN treatment was not associated with excess mortality when compared to the rates observed with other oral hypoglycemic agent therapies.

There were six serious adverse events of myocardial ischemia in patients treated with PRANDIN plus NPH-insulin from two studies, and one event in patients using insulin formulations alone from another study. Infrequent Adverse Events (<1% of Patients) Less common adverse clinical or laboratory events observed in clinical trials included elevated liver enzymes, thrombocytopenia, leukopenia, and anaphylactoid reactions. Although no causal relationship with repaglinide has been established, postmarketing experience includes reports of the following rare adverse events: alopecia, hemolytic anemia, pancreatitis, Stevens-Johnson Syndrome, and severe hepatic dysfunction including jaundice and hepatitis. Combination Therapy with Thiazolidinediones During 24-week treatment clinical trials of PRANDIN-rosiglitazone or PRANDIN-pioglitazone combination therapy (a total of 250 patients in combination therapy), hypoglycemia (blood glucose < 50 mg/dL) occurred in 7% of combination therapy patients in comparison to 7% for PRANDIN monotherapy, and 2% for thiazolidinedione monotherapy. Peripheral edema was reported in 12 out of 250 PRANDIN-thiazolidinedione combination therapy patients and 3 out of 124 thiazolidinedione monotherapy patients, with no cases reported in these trials for PRANDIN monotherapy. When corrected for dropout rates of the treatment groups, the percentage of patients having events of peripheral edema per 24 weeks of treatment were 5% for PRANDIN-thiazolidinedione combination therapy, and 4% for thiazolidinedione monotherapy. There were reports in 2 of 250 patients (0.8%) treated with PRANDIN-thiazolidinedione therapy of episodes of edema with congestive heart failure. Both patients had a prior history of coronary artery disease and recovered after treatment with diuretic agents. No comparable cases in the monotherapy treatment groups were reported. Mean change in weight from baseline was +4.9 kg for PRANDIN-thiazolidinedione therapy. There were no patients on PRANDIN-thiazolidinedione combination therapy who had elevations of liver transaminases (defined as 3 times the upper limit of normal levels).
