Description

11 DESCRIPTION INVOKANA ® (canagliflozin) contains canagliflozin, an inhibitor of SGLT2, the transporter responsible for reabsorbing the majority of glucose filtered by the kidney. Canagliflozin, the active ingredient of INVOKANA, is chemically known as (1 S )-1,5-anhydro-1-[3-[[5-(4-fluorophenyl)-2-thienyl]methyl]-4-methylphenyl]-D-glucitol hemihydrate and its molecular formula and weight are C 24 H 25 FO 5 S∙1/2 H 2 O and 453.53, respectively. The structural formula for canagliflozin is: Canagliflozin is practically insoluble in aqueous media from pH 1.1 to 12.9. INVOKANA is supplied as film-coated tablets for oral administration, containing 102 and 306 mg of canagliflozin in each tablet strength, corresponding to 100 mg and 300 mg of canagliflozin (anhydrous), respectively. Inactive ingredients of the core tablet are croscarmellose sodium (E468), hydroxypropyl cellulose (E463), lactose anhydrous, magnesium stearate (E572), and microcrystalline cellulose (E460[i]). The magnesium stearate is vegetable-sourced. The tablets are finished with a commercially available film-coating consisting of the following excipients: iron oxide yellow (E172) (100 mg tablet only), macrogol/PEG3350 (E1521), polyvinyl alcohol (E1203) (partially hydrolyzed), talc (E553b), and titanium dioxide (E171).

To report SUSPECTED ADVERSE REACTIONS, contact Janssen Pharmaceuticals, Inc. at 1-800-526-7736 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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 the rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. INVOKANA has been evaluated in clinical trials in adults and pediatric patients aged 10 years and older with type 2 diabetes mellitus. Additionally, INVOKANA has been studied in clinical trials in adult patients with type 2 diabetes mellitus who also have heart failure or chronic kidney disease. The overall safety profile of INVOKANA was consistent across the studied indications. Clinical Trials in Adult Patients with Type 2 Diabetes Mellitus Pool of Placebo-Controlled Trials for Glycemic Control The data in Table 2 are derived from four 26-week placebo-controlled trials where INVOKANA was used as monotherapy in one trial and as add-on therapy in three trials. These data reflect exposure of 1,667 adult patients to INVOKANA and a mean duration of exposure to INVOKANA of 24 weeks. Patients received INVOKANA 100 mg (N=833), INVOKANA 300 mg (N=834) or placebo (N=646) once daily. The mean age of the population was 56 years and 2% were older than 75 years of age. Fifty percent (50%) of the population was male and 72% were White, 12% were Asian, and 5% were Black or African American. At baseline the population had diabetes for an average of 7.3 years, had a mean HbA 1C of 8.0% and 20% had established microvascular complications of diabetes. Baseline renal function was normal or mildly impaired (mean eGFR 88 mL/min/1.73 m 2 ). Table 2 shows common adverse reactions associated with the use of INVOKANA. These adverse reactions were not present at baseline, occurred more commonly on INVOKANA than on placebo, and occurred in at least 2% of patients treated with either INVOKANA 100 mg or INVOKANA 300 mg. Table 2: Adverse Reactions from Pool of Four 26–Week Placebo-Controlled Trials Reported in ≥ 2% of INVOKANA-Treated Adult Patients The four placebo-controlled trials included one monotherapy trial and three add-on combination trials with metformin HCl, metformin HCl and sulfonylurea, or metformin HCl and pioglitazone. Note: Percentages were weighted by studies. Trial weights were proportional to the harmonic mean of the three treatment sample sizes. Adverse Reaction Placebo N=646 INVOKANA 100 mg N=833 INVOKANA 300 mg N=834 Urinary tract infections Urinary tract infections include the following adverse reactions: Urinary tract infection, Cystitis, Kidney infection, and Urosepsis. 3.8% 5.9% 4.4% Increased urination Increased urination includes the following adverse reactions: Polyuria, Pollakiuria, Urine output increased, Micturition urgency, and Nocturia. 0.7% 5.1% 4.6% Thirst Thirst includes the following adverse reactions: Thirst, Dry mouth,...

Drug Interactions

7 DRUG INTERACTIONS Table 7: Clinically Significant Drug Interactions with INVOKANA UGT Enzyme Inducers Clinical Impact: UGT enzyme inducers decrease canagliflozin exposure which may reduce the effectiveness of INVOKANA. Intervention: For patients with eGFR 60 mL/min/1.73 m 2 or greater, if an inducer of UGTs is administered with INVOKANA, increase the dosage to 200 mg daily in patients currently tolerating INVOKANA 100 mg daily. The total daily dosage may be increased to 300 mg daily in patients currently tolerating INVOKANA 200 mg daily who require additional glycemic control. For patients with eGFR less than 60 mL/min/1.73 m 2 , if an inducer of UGTs is administered with INVOKANA, increase the dosage to 200 mg daily in patients currently tolerating INVOKANA 100 mg daily. Consider adding another antihyperglycemic agent in patients who require additional glycemic control [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ] . Examples: Rifampin, phenytoin, phenobarbital, ritonavir Insulin or Insulin Secretagogues Clinical Impact: The risk of hypoglycemia is increased when INVOKANA is used concomitantly with insulin secretagogues (e.g., sulfonylurea) or insulin. Intervention: Concomitant use may require a lower dosage of the insulin secretagogue or insulin to reduce the risk of hypoglycemia. Digoxin Clinical Impact: Canagliflozin increases digoxin exposure [see Clinical Pharmacology (12.3) ] . Intervention: Monitor patients taking INVOKANA with concomitant digoxin for a need to adjust the dosage of digoxin. Lithium Clinical Impact: Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Intervention: Monitor serum lithium concentration more frequently during INVOKANA initiation and dosage changes. Drug/Laboratory Test Interference Positive Urine Glucose Test Clinical Impact: SGLT2 inhibitors increase urinary glucose excretion which will lead to positive urine glucose tests. Intervention: Monitoring glycemic control with urine glucose tests is not recommended in patients taking SGLT2 inhibitors. Use alternative methods to monitor glycemic control. Interference with 1,5-anhydroglucitol (1,5-AG) Assay Clinical Impact: Measurements of 1,5-AG are unreliable in assessing glycemic control in patients taking SGLT2 inhibitors. Intervention: Monitoring glycemic control with 1,5-AG assay is not recommended in patients taking SGLT2 inhibitors. Use alternative methods to monitor glycemic control. See full prescribing information for information on drug interactions and interference of INVOKANA with laboratory tests ( 7 ).

Contraindications

4 CONTRAINDICATIONS INVOKANA is contraindicated in patients with a serious hypersensitivity reaction to INVOKANA, such as anaphylaxis or angioedema [see Warnings and Precautions (5.8) and Adverse Reactions (6.1 , 6.2) ] .

Serious hypersensitivity reaction to INVOKANA ( 4 )

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary Based on juvenile animal data showing adverse renal effects, INVOKANA is not recommended during the second and third trimesters of pregnancy. Limited data with INVOKANA in pregnant women are not sufficient to determine a drug-associated risk for major birth defects or miscarriage. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations ]. In juvenile animal studies, adverse renal pelvic and tubule dilatations that were not reversible were observed in rats when canagliflozin was administered during a period of renal development corresponding to the late second and third trimesters of human pregnancy, at an exposure 0.5-times the 300 mg clinical dose, based on AUC. The estimated background risk of major birth defects is 6–10% in women with pre-gestational diabetes with a HbA 1C >7 and has been reported to be as high as 20–25% in women with a HbA 1C >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 2–4% and 15–20%, 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. Animal Data Canagliflozin dosed directly to juvenile rats from postnatal day (PND) 21 until PND 90 at doses of 4, 20, 65, or 100 mg/kg increased kidney weights and dose dependently increased the incidence and severity of renal pelvic and tubular dilatation at all doses tested. Exposure at the lowest dose was greater than or equal to 0.5-times the 300 mg clinical dose, based on AUC. These outcomes...

Overdosage

10 OVERDOSAGE In the event of an overdose, contact the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations. It is also reasonable to employ the usual supportive measures, e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring, and institute supportive treatment as dictated by the patient's clinical status. Canagliflozin was negligibly removed during a 4-hour hemodialysis session. Canagliflozin is not expected to be dialyzable by peritoneal dialysis.
