VA Principal Investigators plan to gather information about veterans at the VAHCS who are interested in participating in rehabilitation research. Subject information collected will be housed in a centralized Rehabilitation Research Repository. VAHCS investigators may access this repository to quickly identify and recruit individuals who wish to be contacted for current and future VA IRB R&D approved rehabilitation research.

An 81-week clinical research study to compare the effect on body weight loss of CagriSema 2.4 mg vs. tirzepatide (known as Mounjaro) 15 mg weekly, along with a reduced-calorie diet and increased physical activity in participants with obesity.
The medicines are injected subcutaneously (under the skin) once a week.

Subjects meet inclusion for this study based on obesity (a high body mass index (BMI), which means too much weight for an individual's height), and they have Heart Failure with Preserved Ejection Fraction (HFpEF). This is a condition where the lower left chamber (left ventricle) of the heart is not able to fill properly with blood during the filling phase and the amount of blood pumped out to the body is below normal.
This study will help to find the best dose of HU6 for treating HFpEF, will help to see its impact on weight reduction, and will help to see its effect on subjects' ability to exercise and on how well they feel.
The study is a placebo-controlled double-blind study that will last approximately 28 weeks. There will be 8 clinic visits (approx. 6-8 hours), and 7 phone visits (approx. 20 minutes). The study drug will be capsules taken orally in the morning before eating.
Possible risks are loose bowel movements/diarrhea which was most prominent within the first 2-3 three weeks of dosing and seemed to improve with time and flushing, especially when alcohol is consumed.

This is a randomized, double-blinded, placebo-controlled phase 2b clinical trial to characterize, examine and compare the effects of GLP-1 receptor agonist (semaglutide) in HIV-infected adult individuals with lipohypertrophy versus healthy controls with obesity but without HIV.

The two populations will be studied in separate but similarly-designed studies running in parallel.

Subjects in both populations will be assigned by chance (1:1) to semaglutide or placebo.
