Abstract

The present disclosure relates to compositions, kits, uses, systems and methods related to naltrexone plus bupropion for treating an overweight or obese subject at increased risk of adverse cardiovascular outcomes. Preferably, the subject has had type-two diabetes for a period of less than 6 years or is a current smoker, optionally that does not have type-two diabetes.

Claims

1. A method of treating a subject for overweight or obesity, comprising:

selecting for treatment an overweight or obese subject at increased risk of a major adverse cardiovascular event that has had type-two diabetes for a period of less than 6 years; and

treating the subject for overweight or obesity by administering to the subject a daily dose of 32 mg of sustained release naltrexone, or a pharmaceutically acceptable salt thereof and 360 mg bupropion, or a pharmaceutically acceptable salt thereof, for a period of at least 12 weeks, wherein said administering reduces the risk of a major adverse cardiovascular event in said overweight or obese subject.

3. The method of claim 1, wherein the subject was administered:

about 8 mg of said sustained release naltrexone or a pharmaceutically acceptable salt thereof and about 90 mg of said sustained release bupropion or a pharmaceutically acceptable salt thereof daily for a first week of treatment;

about 16 mg of said sustained release naltrexone or a pharmaceutically acceptable salt thereof and about 180 mg of said sustained release bupropion or a pharmaceutically acceptable salt thereof daily for a second week of treatment;

about 24 mg of said sustained release naltrexone or a pharmaceutically acceptable salt thereof and about 270 mg of said sustained release bupropion or a pharmaceutically acceptable salt thereof daily for a third week of treatment; and

about 32 mg of said sustained release naltrexone or a pharmaceutically acceptable salt thereof and about 360 mg of said sustained release bupropion or a pharmaceutically acceptable salt thereof daily for a fourth week of treatment and any subsequent weeks of treatment.

4. The method of claim 1, wherein the period of treatment is at least 20 weeks.

2. A method of treating a subject for overweight or obesity, comprising:

selecting for treatment an overweight or obese subject at increased risk of a major adverse cardiovascular event that is a current smoker that does not have type-two diabetes; and

treating the subject for overweight or obesity by administering to the subject a daily dose of 32 mg of sustained release naltrexone and 360 mg bupropion, or a pharmaceutically acceptable salts thereof, for a period of at least 12 weeks, wherein said administrating reduces the risk of a major adverse cardiovascular event in said overweight or obese subject.

5. The method of claim 2, wherein the subject was administered:

about 8 mg of said sustained release naltrexone or a pharmaceutically acceptable salt thereof and about 90 mg of said sustained release bupropion or a pharmaceutically acceptable salt thereof daily for a first week of treatment;

about 16 mg of said sustained release naltrexone or a pharmaceutically acceptable salt thereof and about 180 mg of said sustained release bupropion or a pharmaceutically acceptable salt thereof daily for a second week of treatment;

about 24 mg of said sustained release naltrexone or a pharmaceutically acceptable salt thereof and about 270 mg of said sustained release bupropion or a pharmaceutically acceptable salt thereof daily for a third week of treatment; and

about 32 mg of said sustained release naltrexone or a pharmaceutically acceptable salt thereof and about 360 mg of said sustained release bupropion or a pharmaceutically acceptable salt thereof daily for a fourth week of treatment and any subsequent weeks of treatment.

6. The method of claim 2, wherein the period of treatment is at least 20 weeks.
