Raritan, N.J., June 11, 2016 – Janssen Research & Development, LLC (Janssen) will announce findings of a multicenter, randomized, Phase 2 proof-of-concept clinical trial showing the combination therapy of canagliflozin, a sodium-glucose co-transporter 2 (SGLT2) inhibitor, and phentermine was effective for weight loss in overweight or obese non-diabetic adults. These data were accepted as a late-breaking poster presentation at the 76th Annual Scientific Sessions of the American Diabetes Association (ADA) taking place June 10-14, 2016 in New Orleans, La. Canagliflozin is currently indicated for the treatment of adults with type 2 diabetes mellitus (T2DM), and is not indicated for the treatment of chronic weight management.
This 26-week, randomized Phase 2 trial, consisting of 334 adults, evaluated the safety and efficacy of canagliflozin in combination with phentermine across four arms. Canagliflozin 300 mg with phentermine 15 mg; phentermine 15 mg; canagliflozin 300 mg; or placebo was administered to adults without T2DM and a body mass index (BMI) of 30 to <50 kg/m2 or, if with hypertension and/or dyslipidemia, a BMI of 27 to <50 kg/m2 (mean weight, 102.9 kg; BMI, 37.3 kg/m2). At 26 weeks, patients in the canagliflozin with phentermine arm experienced a significant placebo-subtracted reduction in systolic blood pressure (–4.2 mmHg; P = 0.015) and demonstrated statistically superior weight loss compared to placebo, with the canagliflozin with phentermine, phentermine, canagliflozin and placebo arms producing weight decreases of 7.5%, 4.1%, 1.9% and 0.6% compared to baseline respectively (P <0.001). Additionally, among the patients observed throughout the 26 week duration of the study, significantly more achieved ≥5% weight loss in the canagliflozin with phentermine arm vs. placebo (66.7% vs 17.5%; P <0.001). The coadministration of canagliflozin and phentermine was well tolerated with no new or unexpected safety signals.
“The findings support the potential clinical impact that canagliflozin could have on the lives of people constantly having to manage their weight,” said James F. List, M.D., Ph.D., Global Therapeutic Head, Cardiovascular & Metabolism, Janssen. “We are committed to pursuing transformational therapies and hope to grow our understanding of how canagliflozin can be used to help more patients in the future.”
In March 2013, the U.S. FDA approved canagliflozin – INVOKANA® – as a single agent. In two studies comparing INVOKANA® plus metformin to current standard treatments plus metformin – one studying sitagliptin[i] and the other studying glimepiride[ii] – 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 adverse events 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.[iii] It is also the second most common branded therapy prescribed by primary care physicians when adding or switching therapies in patients.[iv] Since its launch, more than 8 million prescriptions have been written for INVOKANA®.[v]

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): Bone fractures have been seen in patients taking INVOKANA®. 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.
Tell your doctor if you have any side effect that bothers you or that does not go away. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. You may also report side effects to Janssen Scientific Affairs, LLC at 1-800-526-7736.
