Study results published in the New England Journal of Medicine and featured in a special symposium at the American Diabetes Association 77th Scientific Sessions
TORONTO, June 12, 2017 /CNW/ - Results from the landmark CANVAS Program showed INVOKANA® (canagliflozin) significantly reduced the combined risk of cardiovascular (CV) death, myocardial infarction (MI), and nonfatal stroke, versus placebo in patients with type 2 diabetes mellitus (T2DM) at risk for or with a history of CV disease. The results also showed canagliflozin treatment was associated with a reduced risk for hospitalization for heart failure (HHF) and demonstrated potential renal protective effects. These data from the integrated analysis of the CANVAS and CANVAS-R trials were published in the New England Journal of Medicine, and presented in a special symposium at the American Diabetes Association 77th Scientific Sessions on Monday, June 12, in San Diego, CA.
Canagliflozin was studied in the longest, largest and broadest completed CV outcomes program of any sodium glucose cotransporter-2 (SGLT2) inhibitor. The CANVAS Program is the first program to assess the efficacy, safety and durability of canagliflozin in more than 10,000 patients with T2DM, who had either a prior history of CV disease, or at least two CV risk factors.
Canagliflozin achieved a 14% reduction in the risk of the composite primary endpoint of CV mortality, nonfatal MI, or nonfatal stroke (HR: 0.86; 95% CI: 0.75 to 0.97), and demonstrated the CV safety of canagliflozin (p<0.0001 for non-inferiority) and superiority compared to placebo (p=0.0158). Each component evenly contributed to this risk reduction, including nonfatal MI by 15% (HR: 0.85; 95% CI: 0.69 to 1.05), CV death by 13% (HR: 0.87; 95% CI: 0.72 to 1.06), and nonfatal stroke by 10% (HR: 0.90; 95% CI: 0.71 to 1.15). These outcomes were broadly consistent across various patient subgroups, and across the individual composite primary endpoint.
Additional analysis further revealed canagliflozin lowered the risk of HHF by 33% (HR: 0.67; 95% CI: 0.52 to 0.87), and provided sustained positive effects on glycemic and blood pressure control, as well as weight reduction, demonstrating wide-ranging durability.
In addition, canagliflozin showed potential renal protective effects, delaying progression of albuminuria and reducing the risk of clinically important renal composite outcomes (such as renal death, renal replacement therapy, and 40% reduction of eGFR) by 40% (HR: 0.60; 95% CI: 0.47 to 0.77).The ongoing, fully enrolled CREDENCE study, the first dedicated SGLT2 inhibitor renal outcome trial in patients with T2DM and kidney disease, is further evaluating the effects of canagliflozin on renal and CV outcomes.
"The CANVAS results are important because they clearly demonstrate the benefit of canagliflozin over current standard-of-care treatments," said Dr. Vincent Woo, CANVAS Program investigator and endocrinologist at the Diabetes Research Group, University of Manitoba. "The CANVAS Program demonstrated consistent reductions across all components of the primary study outcome, which were cardiovascular death, myocardial infarction and stroke. These results confirm the efficacy of canagliflozin for CV risks that patients living with type-2 diabetes are most likely to experience."
Overall adverse events seen in the CANVAS Program were consistent with previous findings. An increased risk of amputation with canagliflozin was seen in both the completed CANVAS study and in the CANVAS-R study. This is consistent with the observation made by the study's Independent Data Monitoring Committee (IDMC) in 2016, and interim data from the CANVAS study shared with Health Canada in March 2016 and reflected in the current Product Monograph. In the completed CANVAS Program, there was an increased risk of amputation (6.3 vs. 3.4/1000 patient-years in the canagliflozin vs. the placebo arm) corresponding to a hazard ratio (HR) of 1.97. The highest absolute risk of amputation occurred in patients with a prior history of amputation or peripheral vascular disease, but the relative risk for amputation with canagliflozin was comparable across these subgroups.
Separately, while an increased risk of adjudicated low trauma fracture was identified in the CANVAS study and reflected in the Canadian Product Monograph, no increase was observed in the CANVAS-R study. A full assessment is ongoing to provide a complete safety review of these results.
About the CANVAS Program
The CANVAS Program is composed of two, nearly-identical large outcomes studies CANVAS (CANagliflozin CardioVascular Assessment Study, (NCT01032629) and CANVAS-R (Study of the Effects of Canagliflozin on Renal Endpoints in Adult Subjects with T2DM, (NCT01989754).
The CANVAS Program is the largest completed CV outcomes program of any SGLT2 inhibitor to date, with a total of 10,142 patients – 4,330 patients in CANVAS and 5,812 patients in CANVAS-R. In the randomized, placebo-controlled Phase 3/4 studies, a vast majority of patients were obese, with a history of hypertension, and 66% of patients had a history of CV disease (14% had a history of heart failure) and 34% of patients had at least two CV risk factors. The study assessed the safety of canagliflozin relative to placebo in patients receiving specific commonly-used diabetes agents. The primary endpoint was defined as major adverse CV events (MACE), composed of nonfatal MI, nonfatal stroke, and CV death, and the secondary endpoint was defined as progression of albuminuria, beta-cell function, eGFR changes and UACR.
In the CANVAS study, patients were randomly assigned in a 1:1:1 ratio to placebo, canagliflozin 100mg and canagliflozin 300mg. The mean and median exposure to investigational product was approximately 4.3 and 5.8 years, respectively. The mean and median follow-up time was 5.7 and 6.1 years, respectively.
In the CANVAS-R study, patients were randomly assigned in a 1:1 ratio to placebo or canagliflozin 100mg (with an investigator option to up-titrate to 300mg if the patient required additional glycemic control, provided the 100mg dosage was well tolerated). The mean and median exposure to investigational product was approximately 1.8 and 1.9 years, respectively. The mean and median follow-up time was 2.1 years.
These CANVAS and CANVAS-R studies were designed to be highly similar in patient population, procedures and assessments, evaluating the effects of canagliflozin on CV events in a similar study population. This approach is demonstrated in three published studies: "Rationale, design, and baseline characteristics of the Canagliflozin Cardiovascular Assessment Study (CANVAS)—A randomized placebo-controlled trial," published online by American Heart Journal; "Rationale, design and baseline characteristics of the CANagliflozin cardioVascular Assessment Study–Renal (CANVAS-R): A randomized, placebo-controlled trial," published online by Diabetes, Obesity and Metabolism; and "Optimizing the analysis strategy for the CANVAS Program – a pre-specified plan for the integrated analyses of the CANVAS and CANVAS-R trials," published online by Diabetes, Obesity and Metabolism.
INVOKANA® was approved in the United States in March 2013 and in Canada in May 2014 based on a comprehensive global Phase 3 clinical program, including 713 Canadians in six studies, which was one of the largest global clinical programs in type 2 diabetes ever conducted. INVOKANA® has been studied as a single agent (monotherapy), in combination with metformin and in combination with other glucose-lowering agents, including insulin, in patients who need further glucose control.
Results from this program showed that the 100 mg and the 300 mg doses of INVOKANA® significantly improved glycemic control, body weight and systolic blood pressure.
In two studies comparing INVOKANA® as an add-on therapy with metformin to current standard treatments, INVOKANA® dosed at 300 mg provided superior reductions compared to sitagliptin and to glimepiride in both A1C levels (measure that reflects the average blood sugar levels over the past three months) and body weight.
INVOKANA® is currently approved as a single agent in 79 countries and continues to be the number-one prescribed SGLT2 inhibitor leading with more prescriptions than all other SGLT2 inhibitors combined in U.S. in 2017*.

WHAT IS INVOKANA®?
INVOKANA® is a prescription medicine used along with diet and exercise to lower blood sugar in adults with type 2 diabetes. INVOKANA® is not for people with type 1 diabetes or with diabetic ketoacidosis (increased ketones in blood or urine). It is not known if INVOKANA® is safe and effective in children under 18 years of age.
IMPORTANT SAFETY INFORMATION
INVOKANA® can cause important side effects, including:
- Dehydration. INVOKANA® can cause some people to become dehydrated (the loss of too much body water), which may cause you to feel dizzy, faint, lightheaded, or weak, especially when you stand up (orthostatic hypotension). You may be at higher risk of dehydration if you have low blood pressure, take medicines to lower your blood pressure (including diuretics [water pills]), are on a low sodium (salt) diet, have kidney problems, or are 65 years of age or older
- Vaginal yeast infection. Women who take INVOKANA® may get vaginal yeast infections. Symptoms include: vaginal odor, white or yellowish vaginal discharge (discharge may be lumpy or look like cottage cheese), or vaginal itching
- Yeast infection of the penis (balanitis or balanoposthitis). Men who take INVOKANA® may get a yeast infection of the skin around the penis. Symptoms include: redness, itching, or swelling of the penis; rash of the penis; foul-smelling discharge from the penis; or pain in the skin around penis
Talk to your doctor about what to do if you get symptoms of a yeast infection of the vagina or penis.
Do not take INVOKANA® if you:
- are allergic to canagliflozin or any of the ingredients in INVOKANA®. Symptoms of allergic reaction may include: rash; raised red patches on your skin (hives); or swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing
- have severe kidney problems or are on dialysis
Before you take INVOKANA®, tell your doctor if you have kidney problems; liver problems; history of urinary tract infections or problems with urination; are on a low sodium (salt) diet; are going to have surgery; are eating less due to illness, surgery, or change in diet; pancreas problems; drink alcohol very often (or drink a lot of alcohol in short-term); ever had an allergic reaction to INVOKANA®; or have other medical conditions.
Tell your doctor if you are or plan to become pregnant, are breastfeeding, or plan to breastfeed. INVOKANA® may harm your unborn baby. If you become pregnant while taking INVOKANA®, tell your doctor right away. INVOKANA® may pass into your breast milk and may harm your baby. Do not breastfeed while taking INVOKANA®.
Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Especially tell your doctor if you take diuretics (water pills), rifampin (used to treat or prevent tuberculosis), phenytoin or phenobarbital (used to control seizures), ritonavir (Norvir®, Kaletra® – used to treat HIV infection), or digoxin (Lanoxin®– used to treat heart problems).
Possible Side Effects of INVOKANA®
INVOKANA® may cause serious side effects, including:
- Ketoacidosis (increased ketones in your blood or urine). Ketoacidosis has happened in people who have type 1 or type 2 diabetes, during treatment with INVOKANA®. Ketoacidosis can be life-threatening and may need to be treated in a hospital. Ketoacidosis can happen with INVOKANA® even if your blood sugar is less than 250 mg/dL. Stop taking INVOKANA® and call your doctor right away if you get any of the following symptoms: nausea, vomiting, stomach-area pain, tiredness, or trouble breathing
- Kidney problems. Sudden kidney injury has happened to people taking INVOKANA®. Talk to your doctor right away if you: 1) reduce the amount of food or liquid you drink, if you are sick, or cannot eat or 2) you start to lose liquids from your body from vomiting, diarrhea, or being in the sun too long
- A high amount of potassium in your blood (hyperkalemia)
- Serious Urinary Tract Infections: may lead to hospitalization and have happened in people taking INVOKANA®. Tell your doctor if you have signs or symptoms of a urinary tract infection such as: burning feeling while urinating, need to urinate often or right away, pain in the lower part of your stomach (pelvis), or blood in the urine. Some people may also have high fever, back pain, nausea, or vomiting
- Low blood sugar (hypoglycemia). If you take INVOKANA® with another medicine that can cause low blood sugar, such as a sulfonylurea or insulin, your risk of getting low blood sugar is higher. The dose of your sulfonylurea medicine or insulin may need to be lowered while you take INVOKANA®
Signs and symptoms of low blood sugar may include: headache, drowsiness, weakness, dizziness, confusion, irritability, hunger, fast heartbeat, sweating, shaking, or feeling jittery.
Serious allergic reaction. If you have any symptoms of a serious allergic reaction, stop taking INVOKANA® and call your doctor right away or go to the nearest hospital emergency room.
Broken Bones (fractures): Taking INVOKANA® increases your risk of breaking a bone. Talk to your doctor about factors that may increase your risk of bone fracture.
The most common side effects of INVOKANA® include: vaginal yeast infections and yeast infections of the penis; changes in urination, including urgent need to urinate more often, in larger amounts, or at night.
