Adverse Reactions

6 ADVERSE REACTIONS The following serious adverse reaction is also described elsewhere in the labeling: Hypoglycemia [see Warnings and Precautions (5.1) ] Common adverse reactions associated with Nateglinide Tablets (3% or greater incidence) were upper respiratory tract infection, back pain, flu symptoms, dizziness, arthropathy, diarrhea. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Rising Pharma Holdings, Inc. at 1-844-874-7464 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials 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. In clinical trials, approximately 2,600 patients with type 2 diabetes mellitus were treated with Nateglinide Tablets. Of these, approximately 1,335 patients were treated for 6 months or longer and approximately 190 patients for one year or longer. Table 1 shows the most common adverse reactions associated with Nateglinide Tablets.

Overdosage

10 OVERDOSAGE There have been no instances of overdose with Nateglinide Tablets in clinical trials. However, an overdose may result in an exaggerated glucose-lowering effect with the development of hypoglycemic symptoms. Hypoglycemic symptoms without loss of consciousness or neurological findings should be treated with oral glucose and adjustments in dosage and/or meal patterns. Severe hypoglycemic reactions with coma, seizure, or other neurological symptoms should be treated with intravenous glucose. As Nateglinide Tablets are highly protein bound, dialysis is not an efficient means of removing it from the blood.

Clinical Pharmacology

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Nateglinide lowers blood glucose levels by stimulating insulin secretion from the pancreas. This action is dependent upon functioning beta-cells in the pancreatic islets. Nateglinide interacts with the ATP- sensitive potassium (K + ATP ) channel on pancreatic beta-cells. The subsequent depolarization of the beta cell opens the calcium channel, producing calcium influx and insulin secretion. The extent of insulin release is glucose dependent and diminishes at low glucose levels. Nateglinide is highly tissue selective with low affinity for heart and skeletal muscle. 12.2 Pharmacodynamics Nateglinide Tablets stimulate pancreatic insulin secretion within 20 minutes of oral administration. When Nateglinide Tablets are dosed before meals, the peak rise in plasma insulin occurs approximately 1 hour after dosing and falls to baseline by 4 hours after dosing. 12.3 Pharmacokinetics In patients with Type 2 diabetes, multiple dose administration of nateglinide over the dosage range of 60 mg to 240 mg shows linear pharmacokinetics for both area under the curve (AUC) and C max . In patients with Type 2 diabetes, there is no apparent accumulation of nateglinide upon multiple dosing of up to 240 mg three times daily for 7 days. Absorption Absolute bioavailability of nateglinide is approximately 73%. Plasma profiles are characterized by multiple plasma concentration peaks when nateglinide is administered under fasting conditions. This effect is diminished when nateglinide is taken prior to a meal. Following oral administration immediately prior to a meal, the mean peak plasma nateglinide concentrations (C max ) generally occur within 1 hour (T max ) after dosing. T max is independent of dose. The pharmacokinetics of nateglinide are not affected by the composition of a meal (high protein, fat, or carbohydrate). However, peak plasma levels are significantly reduced when Nateglinide Tablets are administered 10 minutes prior to a liquid meal as compared to solid meal. When given with or after meals, the extent of nateglinide absorption (AUC) remains unaffected. However, there is a delay in the rate of absorption characterized by a decrease in C max and a delay in time to peak plasma concentration (T max ). Nateglinide Tablets did not have any effect on gastric emptying in healthy subjects as assessed by acetaminophen testing. Distribution Following intravenous (IV) administration of nateglinide, the steady-state volume of distribution of nateglinide is estimated to be approximately 10 L in healthy subjects. Nateglinide is extensively bound (98%) to serum proteins, primarily serum albumin, and to a lesser extent α 1 acid glycoprotein. The extent of serum protein binding is independent of drug concentration over the test range of 0.1 to 10 mcg/mL. Elimination In healthy volunteers and patients with type 2 diabetes mellitus, nateglinide plasma concentrations declined with an average elimination half-life of approximately 1.5 hours. Metabolism In vitro drug metabolism studies indicate that Nateglinide Tablets are predominantly metabolized by the cytochrome P450 isozyme CYP2C9 (70%) and to a lesser extent CYP3A4 (30%). The major routes of metabolism are hydroxylation followed by glucuronide conjugation. The major metabolites are less potent antidiabetic agents than nateglinide. The isoprene minor metabolite possesses potency similar to that of the parent compound nateglinide. Excretion Nateglinide and its metabolites are rapidly and completely eliminated following oral administration. Eighty-three percent of the 14 C -nateglinide was excreted in the urine with an additional 10% eliminated in the feces. Approximately 16% of the 14 C -nateglinide was excreted in the urine as parent compound. Specific Populations Renal Impairment No pharmacokinetic data are available in subjects with mild renal impairment (CrCl 60 to 89 mL/min). Compared to healthy matched subjects, patients with type 2 diabetes mellitus and moderate and severe renal impairment (CrCl 15-50 mL/min) not on dialysis displayed similar apparent clearance, AUC, and C max . Patients with type 2 diabetes and renal failure on dialysis exhibited reduced overall drug exposure (C max decreased by 49%; not statistically significant). However, hemodialysis patients also experienced reductions in plasma protein binding compared to the matched healthy volunteers. In a cohort of 8 patients with type 2 diabetes and end-stage renal disease (ESRD) (eGFR < 15 mL/min/1.73m 2 ) M1 metabolite accumulation up to 1.2 ng/mL occurred with a dosage of 90 mg once daily for 1 to 3 months. In another cohort of 8 patients with type 2 diabetes on hemodialysis, M1 concentration decreased after a single session of hemodialysis. Although the hypoglycemic activity of the M1 metabolite is approximately 5 times lower than nateglinide, metabolite accumulation may increase the hypoglycemic effect of the administered dose. Hepatic Impairment In patients with mild hepatic impairment, the mean increase in C max and AUC of nateglinide were 37% and 30 % respectively, as compared to healthy matched control subjects. There is no data on pharmacokinetics of Nateglinide Tablets in patients with moderate-to-severe hepatic impairment. Gender No clinically significant differences in nateglinide pharmacokinetics were observed between men and women. Race Results of a population pharmacokinetic analysis including subjects of Caucasian, Black, and other ethnic origins suggest that race has little influence on the pharmacokinetics of nateglinide. Age Age does not influence the pharmacokinetic properties of nateglinide. Drug Interactions: In vitro assessment of drug interactions Nateglinide Tablets are a potential inhibitor of the CYP2C9 isoenzyme in vivo as indicated by its ability to inhibit the in vitro metabolism of tolbutamide. Inhibition of CYP3A4 metabolic reactions was not detected in in vitro experiments. In vitro displacement studies with highly protein-bound drugs such as furosemide, propranolol, captopril, nicardipine, pravastatin, glyburide, warfarin, phenytoin, acetylsalicylic acid, tolbutamide, and metformin showed no influence on the extent of nateglinide protein binding. Similarly, nateglinide had no influence on the serum protein binding of propranolol, glyburide, nicardipine, warfarin, phenytoin, acetylsalicylic acid, and tolbutamide in vitro . However, prudent evaluation of individual cases is warranted in the clinical setting. In vivo assessment of drug interactions The effect of coadministered drugs on the pharmacokinetics of nateglinide and the effect of nateglinide on pharmacokinetics of coadministered drugs are shown in Tables 3 and 4. No clinically relevant change in pharmacokinetic parameters of either agent was reported when nateglinide was coadministered with glyburide, metformin, digoxin, warfarin, and diclofenac.

Carcinogenesis And Mutagenesis And Impairment Of Fertility

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity: Nateglinide did not increase tumors in two year carcinogenicity studies conducted in mice and rats. Oral doses of Nateglinide up to 900 mg/kg in rats and 400 mg/kg in mice were tested, which produced exposures in rats approximately 30-40 times and in mice 10-30 times the human therapeutic exposure of nateglinide at a dose of 120 mg three times daily, based on AUC. Mutagenesis: Nateglinide was not genotoxic in the in vitro Ames test, mouse lymphoma assay, chromosome aberration assay or in the in vivo mouse micronucleus test. Impairment of Fertility: Fertility was unaffected by administration of nateglinide to rats at doses up to 600 mg/kg (corresponding to 16 times the MRHD of 120 mg three times per day, based on BSA).

Clinical Studies

14 CLINICAL STUDIES 14.1 Monotherapy In a 24-week, double-blind, placebo-controlled study, patients with type 2 diabetes were randomized to receive either Nateglinide Tablets (60 mg or 120 mg three times daily before meals) or placebo. Patients previously treated with antidiabetic medications were required to discontinue that medication for at least 2 months before randomization. At Week 24, treatment with Nateglinide Tablets before meals resulted in statistically significant reductions in mean HbA1C and mean fasting plasma glucose (FPG) compared to placebo (see Table 5). The reductions in HbA1C and FPG were similar for patient’s naïve to, and those previously exposed to, antidiabetic medications.

Patients randomized to Nateglinide Tablets had statistically significant increases in mean HbA1C and mean FPG at endpoint compared to patients randomized to glyburide. Table 6: Endpoint Results for a 24-Week Study of Nateglinide Tablets Monotherapy Compared to Glyburide Glyburide 10 mg Once daily Nateglinide Tablets 60 mg three times daily before meals Nateglinide Tablets 120 mg three times daily before meals HbA 1C (%) N=183 N=178 N=179 Baseline (mean) 7.8 8.0 7.9 Change from baseline (mean) 0.3 1.3 1.1 Difference from glyburide 1.0 a 0.9 a FPG (mmol/L) N=184 N=182 N=180 Baseline (mean) 9.44 9.67 9.61 Change from baseline (mean) 0.19 3.06 2.84 Difference from glyburide 2.87 a 2.66 a a p-value <0.001 14.3 Monotherapy and In Combination with Metformin In a 24-week, double-blind, active- and placebo-controlled study, patients with type 2 diabetes were randomized to receive either Nateglinide Tablets alone (120 mg three times daily before meals), metformin alone (500 mg three times daily), a combination of Nateglinide Tablets 120 mg (three times daily before meals) and metformin (500 mg three times daily), or placebo. Fifty-seven percent of patients were previously untreated with oral antidiabetic therapy. Patients previously treated with antidiabetic medications were required to discontinue medication for at least 2 months before randomization. At Week 24, statistically significant reductions in mean HbA1c and FPG were observed with metformin monotherapy compared to Nateglinide Tablets monotherapy, and the combination of Nateglinide Tablets and metformin compared to either Nateglinide Tablets or metformin monotherapy (see Table 7). Compared to placebo, Nateglinide Tablets monotherapy was associated with a statistically significant increase in mean body weight, while no significant change in body weight was observed with metformin monotherapy or combination of Nateglinide Tablets and metformin therapy (see Table 7). Among the subset of patients previously treated with other antidiabetic agents, primarily glyburide, HbA1C in the Nateglinide Tablets monotherapy group increased slightly from baseline, whereas HbA1C was reduced in the metformin monotherapy group (see Table 7).

The addition of Nateglinide Tablets (120 mg three times per day with meals) was associated with statistically significantly greater reductions in HbA1C compared to placebo as add-on to rosiglitazone. The mean change in weight from baseline was +3 kg for patients treated with Nateglinide Tablets compared to +1 kg for patients treated with placebo when added to rosiglitazone.

Geriatric Use

8.5 Geriatric Use 436 patients 65 years and older, and 80 patients 75 years and older were exposed to Nateglinide Tablets in clinical studies. No differences were observed in safety or efficacy of Nateglinide Tablets between patients age 65 and over, and those under age 65. However, greater sensitivity of some older individuals to Nateglinide Tablets therapy cannot be ruled out.

Pediatric Use

8.4 Pediatric Use The safety and effectiveness of Nateglinide Tablets have not been established in pediatric patients.

Pregnancy

8.1 Pregnancy Risk Summary The available data from published literature and the applicant’s pharmacovigilance with use of Nateglinide Tablets in pregnant women are insufficient to identify a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy ( see Clinical Considerations ). Nateglinide Tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. In animal reproduction studies, there was no teratogenicity in rats and rabbits administered oral nateglinide during organogenesis at approximately 27 and 8 times the maximum recommended human dose (MRHD), respectively, based on body surface area (BSA). The estimated background risk of major birth defects is 6% to 10% in women with pre-gestational diabetes with a HbA1c > 7 and has been reported to be as high as 20% to 25% in women with a HbA1c > 10. The estimated background risk of miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity. Data Animal data In embryofetal development studies, nateglinide administered orally during the period of organogenesis was not teratogenic in rats at doses up to 1,000 mg/kg (corresponding to 27 times the MRHD of 120 mg three times per day, based on BSA). In rabbits, embryonic development was adversely affected at 500 mg/kg/day and the incidence of gallbladder agenesis or small gallbladder was increased at a dose of 300 and 500 mg/kg (corresponding to 16 and 27 times the MRHD). No such effects were observed at 150 mg/kg/day (corresponding to 8 times the MRHD). In a pre- and postnatal development study in rats, nateglinide administered by oral gavage at doses of 100, 300, and 1000 mg/kg/day from gestation day 17 to lactation day 21 resulted in lower body weight in offspring of rats administered nateglinide at 1,000 mg/kg/day (corresponding to 27 times the MHRD).

The drug is present in animal milk. When a drug is present in animal milk, it is likely that the drug will be present in human milk ( see Data ). Because the potential for hypoglycemia in breast-fed infants, advise women that use of Nateglinide Tablets are not recommended while breastfeeding. Data In rat reproduction studies, nateglinide and its metabolite are excreted in the milk following oral dose (300 mg/kg). The overall milk: plasma (M/P) concentration ratio of the total radioactivity was approximately 1.4 based on AUC 0-48 values. The M/P ratio of unchanged nateglinide was approximately 2.2. 8.4 Pediatric Use The safety and effectiveness of Nateglinide Tablets have not been established in pediatric patients. 8.5 Geriatric Use 436 patients 65 years and older, and 80 patients 75 years and older were exposed to Nateglinide Tablets in clinical studies. No differences were observed in safety or efficacy of Nateglinide Tablets between patients age 65 and over, and those under age 65. However, greater sensitivity of some older individuals to Nateglinide Tablets therapy cannot be ruled out. 8.6 Renal Impairment No dosage adjustment is recommended in patients with mild to severe renal impairment [see Clinical Pharmacology (12.3) ]. 8.7 Hepatic Impairment No dose adjustment is recommended for patients with mild hepatic impairment. Use of Nateglinide Tablets in patients with moderate-to-severe hepatic impairment has not been studied and therefore, should be used with caution in these patients [see Clinical Pharmacology (12.3) ].
