The Science Behind CONTRAVE®

CONTRAVE® is a prescription-only, FDA-approved weight-loss medication believed to work on two areas of your brain—the hunger center and the reward system—to reduce hunger and help control cravings.CONTRAVE contains two medicines, bupropion and naltrexone. These well-known drugs have been prescribed separately for years—bupropion for depression and smoking cessation, and naltrexone for alcohol and opioid dependence.2

2The individual components of CONTRAVE are not approved for weight loss. CONTRAVE is not approved to treat depression or other mental illnesses, alcohol or opioid dependency, or to help people quit smoking.

CONTRAVE has a well-studied safety and tolerability profile. Three long-term (56 weeks) studies have shown that patients who add CONTRAVE lose approximately 2 to 4 times more weight than with diet and exercise alone.3 In one study, patients who also participated in an intensive diet and exercise program and remained on CONTRAVE for a full year, lost 25 pounds on average.

3Across three 56-week studies, 46% of patients on CONTRAVE lost 5% or more body weight (vs 23% of patients on placebo). Results may vary.

Across three studies, patients who added CONTRAVE for a full year:

Lost Approximately

2-4x

more weight on average than with diet and exercise alone3

In one study, patients who took CONTRAVE for a full year and participated in intensive behavior modification:

Lost

CONTRAVE was studied for efficacy and safety in
several clinical trials that included thousands of patients.

In three long-term studies,

2,322 participants

were enrolled who were struggling
with obesity (BMI of 30 or greater) or were overweight (BMI of 27 or greater).

Those with a BMI between 27 and 29.9 had at least one weight-related medical condition, such as controlled hypertension, dyslipidemia, or diabetes. While some participants received CONTRAVE, others were randomly selected to receive a placebo. Everyone participated in lifestyle modification programs that included a reduced-calorie diet and regular physical activity.

After 56 weeks, across the three studies,

46%

of patients taking CONTRAVE lost
5% or more
of their body weight with CONTRAVE

vs.
23%

of patients on placebo.

Study 1

In this 56-week study, patients taking CONTRAVE lost 5.4% of their body weight (on average) compared with the placebo group who lost 1.3% (on average) with diet and exercise alone.

Additionally, 42% of the CONTRAVE users lost at least 5% of their total body weight (while 17% of the placebo group lost at least 5% of their total body weight with diet and exercise).

For participants who remained on CONTRAVE for the whole study, average weight loss was 8.1% or approximately 18 pounds, which was 4 times more weight than participants taking placebo.

COR-1 study

Study 2

In this 56-week study, patients participated in an intensive diet and exercise program, including group visits. At 56 weeks, patients taking CONTRAVE lost 8.1% (on average) of their total body weight compared with a body weight loss of 4.9% (on average) for the placebo group.

Additionally, 57% of those who took CONTRAVE lost at least 5% of their total body weight (while 43% of those on placebo lost at least 5% body weight with diet and exercise alone).

For participants who remained on CONTRAVE for the whole study, average weight loss was 11.5% or approximately 25 pounds.

Study 3

For people with type 2 diabetes, CONTRAVE has the potential to provide sustainable weight loss and this weight loss may also lower A1C levels. In this study, patients taking CONTRAVE lost 3.7% of their body weight (on average) compared with the placebo group who lost 1.7% (on average) with diet and exercise alone after 56 weeks.

Additionally, 36% of those who took CONTRAVE lost at least 5% of their total body weight (while 18% of the placebo group lost at least 5% of their total body weight with diet and exercise).

CONTRAVE users also had a reduction in HbA1c of 0.6% (compared with a reduction of 0.1% in the placebo group) at 56 weeks. (Keep in mind that CONTRAVE is not approved to treat diabetes.)

Taking CONTRAVE

If you’re new to CONTRAVE, it’s important to increase your dose slowly over time to help you adjust to the medication. Begin with one morning tablet during your first week, and then gradually work up to two tablets twice a day by week four. Remember to always take your CONTRAVE dose exactly as your doctor prescribes. Refer to this CONTRAVE dosing chart to help you stay on track, and know that some people, like those with renal or hepatic impairment, or those taking other medications, may need to follow a different dosing schedule.

Dosing for most patients taking CONTRAVE

CONTRAVE may help patients make long-term changes to their eating behavior, lose weight, and keep it off. Across three long-term studies, patients taking CONTRAVE lost approximately 2-4x more weight than with diet and exercise alone. In one study, patients who stayed on CONTRAVE for a full year and participated in intensive behavior modification lost 25 pounds on average.

For people with type 2 diabetes, sustainable weight loss with CONTRAVE may improve other areas of their health, like improved blood glucose levels. In one study, CONTRAVE users with type 2 diabetes had a reduction in HbA1c levels at 56 weeks. Please note that CONTRAVE is not approved to treat any other health condition, such as type 2 diabetes.

If you have not lost at least 5% of your body weight after 16 weeks of taking CONTRAVE, your healthcare provider might tell you to stop taking it. CONTRAVE does not work for everyone in the same way.

CONTRAVE was studied for efficacy and safety in numerous clinical trials that included thousands of patients.

Some people taking CONTRAVE experience nausea as they increase their dose. But for most people, this symptom went away within the first four weeks of taking CONTRAVE.

Other common side effects include constipation, headache, vomiting, dizziness, trouble sleeping, dry mouth, and diarrhea. Call your doctor if you experience side effects while taking CONTRAVE that bother you or don’t go away while taking CONTRAVE.

Be careful not to take CONTRAVE with high-fat meals, and also avoid drinking a lot of alcohol. Be sure to tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. This is important because CONTRAVE may affect the way other medications work, especially opioid medicines or medicines to help stop taking opioids.
