INVOKANA (canagliflozin) has been studied as monotherapy, in combination with metformin HCl, sulfonylurea, metformin HCl and sulfonylurea, metformin HCl and sitagliptin, metformin HCl and a thiazolidinedione (i.e., pioglitazone), and in combination with insulin (with or without other anti-hyperglycemic agents). The efficacy of INVOKANA was compared to a dipeptidyl peptidase-4 (DPP-4) inhibitor (sitagliptin), both as add-on combination therapy with metformin HCl and sulfonylurea, and a sulfonylurea (glimepiride), both as add-on combination therapy with metformin HCl. INVOKANA was also evaluated in adults 55 to 80 years of age and patients with moderate renal impairment.

Monotherapy

A total of 584 patients with type 2 diabetes inadequately controlled on diet and exercise participated in a 26-week double-blind, placebo-controlled trial to evaluate the efficacy and safety of INVOKANA. The mean age was 55 years, 44% of patients were male, and the mean baseline eGFR was 87 mL/min/1.73 m 2. Patients taking other antihyperglycemic agents (N=281) discontinued the agent and underwent an 8-week washout followed by a 2-week, single-blind, placebo run-in period. Patients not taking oral antihyperglycemic agents (N=303) entered the 2-week, single-blind, placebo run-in period directly. After the placebo run-in period, patients were randomized to INVOKANA 100 mg, INVOKANA 300 mg, or placebo, administered once daily for 26 weeks. 

At the end of treatment, INVOKANA 100 mg and 300 mg once daily resulted in a statistically significant improvement in HbA 1C(p<0.001 for both doses) compared to placebo. INVOKANA 100 mg and 300 mg once daily also resulted in a greater proportion of patients achieving an HbA 1Cless than 7%, in significant reduction in fasting plasma glucose (FPG), in improved postprandial glucose (PPG), and in percent body weight reduction compared to placebo (see Table 10). Statistically significant (p<0.001 for both doses) mean changes from baseline in systolic blood pressure relative to placebo were -3.7 mmHg and -5.4 mmHg with INVOKANA 100 mg and 300 mg, respectively. 

Add-on Combination Therapy with Metformin HCl

A total of 1,284 patients with type 2 diabetes inadequately controlled on metformin HCl monotherapy (greater than or equal to 2,000 mg/day, or at least 1,500 mg/day if higher dose not tolerated) participated in a 26-week, double-blind, placebo- and active-controlled trial to evaluate the efficacy and safety of INVOKANA in combination with metformin HCl. The mean age was 55 years, 47% of patients were male, and the mean baseline eGFR was 89 mL/min/1.73 m 2. Patients already on the required metformin HCl dose (N=1,009) were randomized after completing a 2-week, single-blind, placebo run-in period. Patients taking less than the required metformin HCl dose or patients on metformin HCl in combination with another antihyperglycemic agent (N=275) were switched to metformin HCl monotherapy (at doses described above) for at least 8 weeks before entering the 2-week, single-blind, placebo run-in. After the placebo run-in period, patients were randomized to INVOKANA 100 mg, INVOKANA 300 mg, sitagliptin 100 mg, or placebo, administered once daily as add-on therapy to metformin HCl. 

At the end of treatment, INVOKANA 100 mg and 300 mg once daily resulted in a statistically significant improvement in HbA 1C(p<0.001 for both doses) compared to placebo when added to metformin HCl. INVOKANA 100 mg and 300 mg once daily also resulted in a greater proportion of patients achieving an HbA 1Cless than 7%, in significant reduction in fasting plasma glucose (FPG), in improved postprandial glucose (PPG), and in percent body weight reduction compared to placebo when added to metformin HCl (see Table 11). Statistically significant (p<0.001 for both doses) mean changes from baseline in systolic blood pressure relative to placebo were -5.4 mmHg and -6.6 mmHg with INVOKANA 100 mg and 300 mg, respectively. 

Initial Combination Therapy with Metformin HCl

A total of 1,186 patients with type 2 diabetes inadequately controlled with diet and exercise participated in a 26-week double-blind, active-controlled, parallel-group, 5-arm, multicenter trial to evaluate the efficacy and safety of initial therapy with INVOKANA in combination with metformin HCl extended-release. The median age was 56 years, 48% of patients were male, and the mean baseline eGFR was 87.6 mL/min/1.73 m 2. The median duration of diabetes was 1.6 years, and 72% of patients were treatment naïve. After completing a 2-week single-blind placebo run-in period, patients were randomly assigned for a double-blind treatment period of 26 weeks to 1 of 5 treatment groups (Table 12). The metformin HCl extended-release dose was initiated at 500 mg/day for the first week of treatment and then increased to 1,000 mg/day. Metformin HCl extended-release or matching placebo was up-titrated every 2–3 weeks during the next 8 weeks of treatment to a maximum daily dose of 1,500 to 2,000 mg/day, as tolerated; about 90% of patients reached 2,000 mg/day. 

At the end of treatment, INVOKANA 100 mg and INVOKANA 300 mg in combination with metformin HCl extended-release resulted in a statistically significant greater improvement in HbA 1Ccompared to their respective INVOKANA doses (100 mg and 300 mg) alone or metformin HCl extended-release alone. 

INVOKANA Compared to Glimepiride, Both as Add-on Combination With Metformin HCl Extended-Release

A total of 1,450 patients with type 2 diabetes inadequately controlled on metformin HCl monotherapy (greater than or equal to 2,000 mg/day, or at least 1,500 mg/day if higher dose not tolerated) participated in a 52-week, double-blind, active-controlled trial to evaluate the efficacy and safety of INVOKANA in combination with metformin HCl.

The mean age was 56 years, 52% of patients were male, and the mean baseline eGFR was 90 mL/min/1.73 m 2. Patients tolerating maximally required metformin HCl dose (N=928) were randomized after completing a 2-week, single-blind, placebo run-in period. Other patients (N=522) were switched to metformin HCl monotherapy (at doses described above) for at least 10 weeks, then completed a 2-week single-blind run-in period. After the 2-week run-in period, patients were randomized to INVOKANA 100 mg, INVOKANA 300 mg, or glimepiride (titration allowed throughout the 52-week trial to 6 or 8 mg), administered once daily as add-on therapy to metformin HCl. 

As shown in Table 13 and Figure 1, at the end of treatment, INVOKANA 100 mg provided similar reductions in HbA 1Cfrom baseline compared to glimepiride when added to metformin HCl therapy. INVOKANA 300 mg provided a greater reduction from baseline in HbA 1Ccompared to glimepiride, and the relative treatment difference was -0.12% (95% CI: –0.22; –0.02). As shown in Table 13, treatment with INVOKANA 100 mg and 300 mg daily provided greater improvements in percent body weight change, relative to glimepiride. 

Add-on Combination Therapy with Sulfonylurea

A total of 127 patients with type 2 diabetes inadequately controlled on sulfonylurea monotherapy participated in an 18-week, double-blind, placebo-controlled sub-study to evaluate the efficacy and safety of INVOKANA in combination with sulfonylurea. The mean age was 65 years, 57% of patients were male, and the mean baseline eGFR was 69 mL/min/1.73 m 2. Patients treated with sulfonylurea monotherapy on a stable protocol-specified dose (greater than or equal to 50% maximal dose) for at least 10 weeks completed a 2-week, single-blind, placebo run-in period. After the run-in period, patients with inadequate glycemic control were randomized to INVOKANA 100 mg, INVOKANA 300 mg, or placebo, administered once daily as add-on to sulfonylurea. 

As shown in Table 14, at the end of treatment, INVOKANA 100 mg and 300 mg daily provided statistically significant (p<0.001 for both doses) improvements in HbA 1Crelative to placebo when added to sulfonylurea. INVOKANA 300 mg once daily compared to placebo resulted in a greater proportion of patients achieving an HbA 1Cless than 7%, (33% vs 5%), greater reductions in fasting plasma glucose (-36 mg/dL vs +12 mg/dL), and greater percent body weight reduction (-2.0% vs -0.2%). 

Add-on Combination Therapy with Metformin HCl and Sulfonylurea

A total of 469 patients with type 2 diabetes inadequately controlled on the combination of metformin HCl (greater than or equal to 2,000 mg/day or at least 1,500 mg/day if higher dose not tolerated) and sulfonylurea (maximal or near-maximal effective dose) participated in a 26-week, double-blind, placebo-controlled trial to evaluate the efficacy and safety of INVOKANA in combination with metformin HCl and sulfonylurea. The mean age was 57 years, 51% of patients were male, and the mean baseline eGFR was 89 mL/min/1.73 m 2. Patients already on the protocol-specified doses of metformin HCl and sulfonylurea (N=372) entered a 2-week, single-blind, placebo run-in period. Other patients (N=97) were required to be on a stable protocol-specified dose of metformin HCl and sulfonylurea for at least 8 weeks before entering the 2-week run-in period. Following the run-in period, patients were randomized to INVOKANA 100 mg, INVOKANA 300 mg, or placebo, administered once daily as add-on to metformin HCl and sulfonylurea. 

At the end of treatment, INVOKANA 100 mg and 300 mg once daily resulted in a statistically significant improvement in HbA 1C(p<0.001 for both doses) compared to placebo when added to metformin HCl and sulfonylurea. INVOKANA 100 mg and 300 mg once daily also resulted in a greater proportion of patients achieving an HbA 1Cless than 7%, in a significant reduction in fasting plasma glucose (FPG), and in percent body weight reduction compared to placebo when added to metformin HCl and sulfonylurea (see Table 15). 

Add-on Combination Therapy with Metformin HCl and Sitagliptin

A total of 217 patients with type 2 diabetes inadequately controlled on the combination of metformin HCl (greater than or equal to 1,500 mg/day) and sitagliptin 100 mg/day (or equivalent fixed-dose combination) participated in a 26-week, double-blind, placebo-controlled trial to evaluate the efficacy and safety of INVOKANA in combination with metformin HCl and sitagliptin. The mean age was 57 years, 58% of patients were male, 73% of patients were White, 15% were Asian, and 12% were Black or African American. The mean baseline eGFR was 90 mL/min/1.73 m 2and the mean baseline BMI was 32 kg/m 2. The mean duration of diabetes was 10 years. Eligible patients entered a 2-week, single-blind, placebo run-in period and were subsequently randomized to INVOKANA 100 mg or placebo, administered once daily as add-on to metformin HCl and sitagliptin. Patients with a baseline eGFR of 70 mL/min/1.73 m 2or greater who were tolerating INVOKANA 100 mg and who required additional glycemic control (fasting finger stick 100 mg/dL or greater at least twice within 2 weeks) were up-titrated to INVOKANA 300 mg. While up-titration occurred as early as Week 4, most (90%) patients randomized to INVOKANA were up-titrated to INVOKANA 300 mg by 6 to 8 weeks. 

At the end of 26 weeks, INVOKANA resulted in a statistically significant improvement in HbA 1C(p<0.001) compared to placebo when added to metformin HCl and sitagliptin. 

INVOKANA Compared to Sitagliptin, Both as Add-on Combination Therapy with Metformin HCl and Sulfonylurea

A total of 755 patients with type 2 diabetes inadequately controlled on the combination of metformin HCl (greater than or equal to 2,000 mg/day or at least 1,500 mg/day if higher dose not tolerated) and sulfonylurea (near-maximal or maximal effective dose) participated in a 52-week, double-blind, active-controlled trial to compare the efficacy and safety of INVOKANA 300 mg versus sitagliptin 100 mg in combination with metformin HCl and sulfonylurea. The mean age was 57 years, 56% of patients were male, and the mean baseline eGFR was 88 mL/min/1.73 m 2. Patients already on protocol-specified doses of metformin HCl and sulfonylurea (N=716) entered a 2-week single-blind, placebo run-in period. Other patients (N=39) were required to be on a stable protocol-specified dose of metformin HCl and sulfonylurea for at least 8 weeks before entering the 2-week run-in period. Following the run-in period, patients were randomized to INVOKANA 300 mg or sitagliptin 100 mg as add-on to metformin HCl and sulfonylurea. 

As shown in Table 17 and Figure 2, at the end of treatment, INVOKANA 300 mg provided greater HbA 1Creduction compared to sitagliptin 100 mg when added to metformin HCl and sulfonylurea (p<0.05). INVOKANA 300 mg resulted in a mean percent change in body weight from baseline of -2.5% compared to +0.3% with sitagliptin 100 mg. A mean change in systolic blood pressure from baseline of -5.06 mmHg was observed with INVOKANA 300 mg compared to +0.85 mmHg with sitagliptin 100 mg.

Add-on Combination Therapy with Metformin HCl and Pioglitazone

A total of 342 patients with type 2 diabetes inadequately controlled on the combination of metformin HCl (greater than or equal to 2,000 mg/day or at least 1,500 mg/day if higher dose not tolerated) and pioglitazone (30 or 45 mg/day) participated in a 26-week, double-blind, placebo-controlled trial to evaluate the efficacy and safety of INVOKANA in combination with metformin HCl and pioglitazone. The mean age was 57 years, 63% of patients were male, and the mean baseline eGFR was 86 mL/min/1.73 m 2. Patients already on protocol-specified doses of metformin HCl and pioglitazone (N=163) entered a 2-week, single-blind, placebo run-in period. Other patients (N=181) were required to be on stable protocol-specified doses of metformin HCl and pioglitazone for at least 8 weeks before entering the 2-week run-in period. Following the run-in period, patients were randomized to INVOKANA 100 mg, INVOKANA 300 mg, or placebo, administered once daily as add-on to metformin HCl and pioglitazone. 

At the end of treatment, INVOKANA 100 mg and 300 mg once daily resulted in a statistically significant improvement in HbA 1C(p<0.001 for both doses) compared to placebo when added to metformin HCl and pioglitazone. INVOKANA 100 mg and 300 mg once daily also resulted in a greater proportion of patients achieving an HbA 1Cless than 7%, in significant reduction in fasting plasma glucose (FPG) and in percent body weight reduction compared to placebo when added to metformin HCl and pioglitazone (see Table 18). Statistically significant (p<0.05 for both doses) mean changes from baseline in systolic blood pressure relative to placebo were -4.1 mmHg and -3.5 mmHg with INVOKANA 100 mg and 300 mg, respectively. 

Add-On Combination Therapy with Insulin (With or Without Other Antihyperglycemic Agents)

A total of 1,718 patients with type 2 diabetes inadequately controlled on insulin greater than or equal to 30 units/day or insulin in combination with other antihyperglycemic agents participated in an 18-week, double-blind, placebo-controlled substudy of a cardiovascular trial to evaluate the efficacy and safety of INVOKANA in combination with insulin. The mean age was 63 years, 66% of patients were male, and the mean baseline eGFR was 75 mL/min/1.73 m 2. Patients on basal, bolus, or basal/bolus insulin for at least 10 weeks entered a 2-week, single-blind, placebo run-in period. Approximately 70% of patients were on a background basal/bolus insulin regimen. After the run-in period, patients were randomized to INVOKANA 100 mg, INVOKANA 300 mg, or placebo, administered once daily as add-on to insulin. The mean daily insulin dose at baseline was 83 units, which was similar across treatment groups. 

At the end of treatment, INVOKANA 100 mg and 300 mg once daily resulted in a statistically significant improvement in HbA 1C(p<0.001 for both doses) compared to placebo when added to insulin. INVOKANA 100 mg and 300 mg once daily also resulted in a greater proportion of patients achieving an HbA 1Cless than 7%, in significant reductions in fasting plasma glucose (FPG), and in percent body weight reductions compared to placebo (see Table 19). Statistically significant (p<0.001 for both doses) mean changes from baseline in systolic blood pressure relative to placebo were -2.6 mmHg and -4.4 mmHg with INVOKANA 100 mg and 300 mg, respectively. 

Study in Patients Ages 55 to 80

A total of 714 type 2 diabetes patients ages 55 to 80 years and inadequately controlled on current diabetes therapy (either diet and exercise alone or in combination with oral or parenteral agents) participated in a 26-week, double-blind, placebo-controlled trial to evaluate the efficacy and safety of INVOKANA in combination with current diabetes treatment. The mean age was 64 years, 55% of patients were male, and the mean baseline eGFR was 77 mL/min/1.73 m 2. Patients were randomized in a 1:1:1 ratio to the addition of INVOKANA 100 mg, INVOKANA 300 mg, or placebo, administered once daily. At the end of treatment, INVOKANA provided statistically significant improvements from baseline relative to placebo in HbA 1C(p<0.001 for both doses) of -0.57% (95% CI: -0.71%; -0.44%) for INVOKANA 100 mg and -0.70% (95% CI: -0.84%; -0.57%) for INVOKANA 300 mg [see Use in Specific Populations (8.5)] . 

Glycemic Control in Patients with Moderate Renal Impairment

A total of 269 patients with type 2 diabetes and a baseline eGFR of 30 mL/min/1.73 m 2to less than 50 mL/min/1.73 m 2inadequately controlled on current diabetes therapy participated in a 26-week, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of INVOKANA in combination with current diabetes treatment (diet or antihyperglycemic agent therapy, with 95% of patients on insulin and/or sulfonylurea). The mean age was 68 years, 61% of patients were male, and the mean baseline eGFR was 39 mL/min/1.73 m 2. Patients were randomized in a 1:1:1 ratio to the addition of INVOKANA 100 mg, INVOKANA 300 mg, or placebo, administered once daily. 

At the end of treatment, INVOKANA 100 mg and INVOKANA 300 mg daily provided greater reductions in HbA 1Crelative to placebo (-0.30% [95% CI: -0.53%; -0.07%] and -0.40%, [95% CI: -0.64%; -0.17%], respectively) [see Warnings and Precautions (5.3), Adverse Reactions (6.1), Use in Specific Populations (8.6), and Clinical Studies (14.3)] .
