About
A randomized, double-blinded, placebo controlled study intended to capture cardiovascular outcomes during real-world use of naltrexone/bupropion (NB).
Full description
This multi-center, prospective, randomized, pragmatic, double-blinded study has been designed to capture cardiovascular (CV) outcomes during the real-world use of NB after initial randomization. The aim of the study is to assess whether patients receiving treatment with NB are at an elevated risk of experiencing MACE compared with patients receiving placebo. Both patient groups will also be counselled to lose weight via a reduced-calorie diet and increased physical activity.

Inclusion criteria
Patient age ≥18 years at screening
Able to understand the key components of the study, as described in the written informed consent document, and willing and able to provide written informed consent
BMI ≥30 kg/m2 (obese) or ≥27 kg/m2 (overweight) in the presence of at least 1 weight-related comorbidity (eg, hypertension, type 2 diabetes mellitus, or dyslipidemia)
At increased risk of adverse cardiovascular outcomes:
In the opinion of the investigator, has a high likelihood of cardiovascular disease with at least 1 of the following:
Type 2 diabetes mellitus with at least 2 of the following:
Patients who have completed a washout (2-weeks or 5 half-lives, whichever is longer) of the prohibited concomitant medication(s) at screening
Subject willing to comply with daily completion of an eDiary using a mobile smartphone application
Exclusion criteria
Using prescription medications, other than Contrave/Mysimba, or surgical or medical device interventions for weight loss
History of MI or stroke within 90 days prior to screening
Uncontrolled hypertension, defined as systolic BP ≥160 mmHg and/or >100 mmHg diastolic BP on the average of 3 seated BP measurements after the patient has been at rest for at least 5 minutes
Meets any of the following criteria:
Seizure disorders or history of seizures, not including subjects with a history of pediatric febrile seizures
Use of other bupropion-containing products (including but not limited to Wellbutrin, Wellbutrin SR, Wellbutrin XL, and Aplenzin)
