12-Week Extension Trial:

Inclusion Criteria

Inclusion criteria are those described for the original 1-year trial (enumerated above). The principal exception from these criteria is that participants will only be required to have a BMI > 27 kg/m2, with or without co-morbidities, to be eligible to participate in the extension study. All participants will have met BMI inclusion criteria when they initiated the use of liraglutide and now will use it, potentially with phentermine 15 mg/d, to facilitate to the maintenance of lost weight. (Liraglutide is approved for chronic weight management, including following successful weight loss.) We do not wish to enroll participants with a BMI < 27 kg/m2 because of the possibility that they could reduce substantially below a BMI of 24.9 kg/m2, the upper limit of "normal" weight.

Exclusion Criteria:

Exclusion criteria will include those listed in the original protocol, including those specific to the use of liraglutide 3.0 mg/d (e.g., family history of medullary thyroid cancer).

Additional exclusion criteria added to the 12-week extension study are specific to the use of phentermine 15 mg/d. They include:

1. Use of monoamine oxidase inhibitors in the past 2 weeks

2. Glaucoma

3. Presence or history of marked agitation

4. History of drug abuse

5. Known hypersensitivity to sympathomimetic amines

6. Current use of selective serotonin re-uptake inhibitors (e.g., fluoxetine, sertraline, etc)

7. Current use of any other weight loss medications (besides liraglutide 3.0 mg/d)

8. History of coronary artery disease
