New Data Show Initial Use of Canagliflozin in Combination with Metformin Extended Release Significantly Improves A1C Levels in Adults with Type 2 Diabetes
Initial Combination Therapy with Canagliflozin and Metformin Extended Release also Showed Significant Weight Reduction versus Metformin XR Alone
RARITAN, N.J., June 6, 2015 /PRNewswire/ -- Janssen Research & Development, LLC (Janssen) today announced results of a phase 3, randomized study showing that the use of initial combination therapy of canagliflozin and metformin extended release (XR) in people with type 2 diabetes with higher A1C levels and who treat their type 2 diabetes with diet and exercise only – where monotherapy is unlikely to be adequate to reach glycemic goals – was effective and generally well tolerated. The data were accepted as a late-breaking poster for presentation during the 75th Annual Scientific Sessions of the American Diabetes Association (ADA).
In the study, patients treated with canagliflozin in combination with metformin XR experienced greater reduction in A1C levels in comparison to those treated with either single agent. Additionally, from a pre-specified secondary endpoint, patients treated with the combination therapy showed significant weight reduction when compared with those treated with metformin XR. Canagliflozin monotherapy at 100mg and 300mg showed similar and non-inferior results in lowering A1C and greater body weight reduction versus metformin XR alone. Canagliflozin as a monotherapy and in combination with metformin is not indicated for weight reduction. Overall, rates of serious adverse events (AEs) were low. Incidences of genital mycotic infections and osmotic diuresis, volume depletion and renal-related AEs and hypoglycemia were higher in the patients with canagliflozin.
"We are excited to share these promising results that further our understanding of how canagliflozin can help patients living with type 2 diabetes," said James F. List, M.D., Ph.D., Global Therapeutic Head, Cardiovascular & Metabolism, Janssen Research & Development. "We are committed to continuing the fight against diabetes by exploring additional potential uses of canagliflozin and pursuing additional transformational treatments for diabetes."
About the Study
The 26-week, phase 3, randomized study was designed to assess the effectiveness of the co-administration of canagliflozin and metformin XR compared with canagliflozin alone, and metformin XR alone in patients with type 2 diabetes mellitus with inadequate control despite treatment with diet and exercise. Additionally, comparisons of canagliflozin to metformin were assessed. Canagliflozin was also evaluated for safety and tolerability.
The study included a total of 1,186 patients with type 2 diabetes with inadequate glycemic control (mean HbA1c baseline of 8.8 percent). Patients were randomized to receive canagliflozin 100mg in combination with metformin XR (median 2000mg/day), canagliflozin 300mg in combination with metformin XR, canagliflozin 100mg, canagliflozin 300mg or metformin XR. Both groups receiving canagliflozin in combination with metformin XR showed statistically superior A1C reductions (change from baseline -1.77 and -1.78, respectively) in comparison to patients treated with either canagliflozin at 100mg (change from baseline -1.30), 300mg (change from baseline -1.37) or metformin XR (change from baseline -1.42) alone.
Significant weight reduction (a pre-specified secondary endpoint) was seen among patients treated with canagliflozin in combination with metformin XR in comparison to patients treated with metformin XR alone.
Overall AE rates were 41.8 percent, 44.3 percent, 37.1 percent, 39.9 percent and 37.6 percent with canagliflozin 100mg in combination with metformin XR, canagliflozin 300mg in combination with metformin XR, canagliflozin 100mg and 300mg and metformin XR, respectively, with low rates of serious AEs. Incidence of genital mycotic infections and osmotic diuresis, volume depletion and renal-related AEs and hypoglycemia were few in number, but higher in all groups treated with canagliflozin in comparison to those treated with metformin XR, with overall low discontinuation rates across groups.
About INVOKANA® and INVOKAMET®/VOKANAMET®
In March 2013, the FDA approved canagliflozin – INVOKANA® – as a single agent. In two studies comparing INVOKANA® plus metformin to current standard treatments plus metformin – one studying sitagliptin1 and the other studying glimepiride2 – INVOKANA® dosed at 300 mg provided greater reductions in A1C levels and body weight than either comparator. In the two studies, the overall incidence of AEs was similar with INVOKANA® and the comparators. INVOKANA® is currently the number-one branded non-insulin type 2 diabetes medication prescribed by U.S. endocrinologists.3 It is also the second most common branded therapy prescribed by primary care physicians when adding or switching therapies in patients.4 Since its launch, more than 4 million prescriptions have been written for INVOKANA®.5
In August 2014, the U.S. FDA approved INVOKAMET®, the first fixed-dose combination tablet in the United States combining canagliflozin and immediate release metformin hydrochloride, for the treatment of adults with type 2 diabetes. The same formulation was approved by the European Commission in April 2014, under the name VOKANAMET® for the treatment of adults with type 2 diabetes mellitus to improve glycemic control.

About Type 2 Diabetes
Of the approximately 29 million people who have diabetes in the United States, 90 to 95 percent of them have type 2 diabetes,6 which is chronic and affects the body's ability to metabolize sugar (glucose), and is characterized by the inability of pancreatic beta cell function to keep up with the body's demand for insulin.
Nearly half of adults with type 2 diabetes do not achieve recommended levels of glucose control, and if left uncontrolled, type 2 diabetes can lead to serious complications.4,7,8 Improved glycemic control has been demonstrated to reduce the onset and progression of these complications.4
WHAT IS INVOKAMET®?
INVOKAMET® contains two prescription medicines called canagliflozin (INVOKANA®) and metformin hydrochloride. It is used along with diet and exercise to improve blood sugar (glucose) control in adults with type 2 diabetes when treatment with either canagliflozin or metformin, or both medications, has not controlled blood sugar. INVOKAMET® is not for people with type 1 diabetes or with diabetic ketoacidosis (increased ketones in blood or urine). It is not known if INVOKAMET® is safe and effective in children under 18 years of age.
IMPORTANT SAFETY INFORMATION
INVOKAMET® can cause serious side effects, including:
- Lactic Acidosis. Metformin, one of the medicines in INVOKAMET®, can cause a rare but serious condition called lactic acidosis (a build-up of lactic acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in the hospital. Stop taking INVOKAMET® and call your doctor right away if you have any of the following symptoms which could be signs of lactic acidosis: feel very weak or tired; have unusual (not normal) muscle pain; have trouble breathing; have unusual sleepiness or sleep longer than usual; have stomach pains, nausea, or vomiting; feel dizzy or lightheaded; or have a slow/irregular heartbeat
You have a higher chance of getting lactic acidosis with INVOKAMET® if you have conditions such as: kidney problems, or your kidneys are affected by certain X-ray tests that use injectable dye; liver problems; congestive heart failure; drink alcohol very often (or drink a lot of alcohol in short-term); get dehydrated; have surgery; have a heart attack, severe infection, or stroke; or are 80 years of age or older and have not had your kidneys tested.
Do not take INVOKAMET® if you:
- Have severe kidney problems or are on dialysis, have a condition called metabolic acidosis or diabetic ketoacidosis (increased ketones in the blood or urine). Are allergic to canagliflozin, metformin, or any of the ingredients in INVOKAMET®. See the end of the Medication Guide for a list of ingredients in INVOKAMET®. Symptoms of allergic reaction may include: rash; raised red patches on your skin (hives); swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing
Before you take INVOKAMET®, tell your doctor if you: have kidney problems, have liver problems, are on a low sodium (salt) diet, have ever had an allergic reaction to INVOKAMET®, or are going to get an injection of dye or contrast agents for an X-ray procedure (INVOKAMET® will need to be stopped for a short time); have heart problems (including congestive heart failure); drink alcohol very often (or drink a lot of alcohol in short term); or have any other medical conditions.
Tell your doctor if you are or plan to become pregnant, are breastfeeding or plan to breastfeed. It is not known if INVOKAMET® will harm your unborn baby. It is also not known if INVOKAMET® passes into your breast milk.
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®, Lopinavir®-used to treat HIV infection), or digoxin (Lanoxin®- used to treat heart problems).
Possible Side Effects of INVOKAMET®
INVOKAMET® may cause serious side effects, including: dehydration- INVOKAMET® can cause some people to have dehydration (the loss of body water and salt), kidney problems, a high amount of potassium in your blood (hyperkalemia), liver problems, or low blood sugar (hypoglycemia). If you take INVOKAMET® 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 INVOKAMET®.
Signs and symptoms of low blood sugar may include: headache, drowsiness, weakness, dizziness, confusion, irritability, hunger, fast heartbeat, sweating, shaking or feeling jittery.
Vaginal yeast infection: Women taking INVOKAMET® may get vaginal yeast infections. Symptoms include: vaginal odor, white or yellowish discharge, or vaginal itching.
Yeast infection of the penis (balanitis or balanoposthitis): Men taking INVOKAMET® may get a yeast infection of the skin around the penis. Symptoms include: redness, itching, or swelling of the penis; rash; foul smelling discharge; or pain in the skin around penis.
Serious allergic reaction: If you have any symptoms of a serious allergic reaction, stop taking INVOKAMET® and call your doctor right away or go to the nearest hospital emergency room.
Low vitamin B12 (vitamin B12 deficiency): Using metformin for long periods of time may cause a decrease in the amount of vitamin B12 in your blood. Your doctor may do blood tests to check your levels.
The most common side effects of INVOKAMET® include: urinary tract infection; changes in urination, including urgent need to urinate more often, in larger amounts, or at night; diarrhea, nausea and vomiting, gas, weakness, indigestion, upset stomach, or headache.
