About this trial

This 12-week randomized, double-blind, placebo-controlled trial will test the hypothesis that Vibegron (brand name GEMTESA) can improve energy metabolism, cardiometabolic risk factors, and physical and cognitive function in middle-aged and older adults with obesity.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Obese (BMI ≥30 kg/m2 or BMI ≥27 kg/m2 with a waist circumference >102 cm for men and >88 cm for women)

Disqualifiers

Major depression

Evidence of cognitive impairment

Uncontrolled diabetes (hemoglobin A1c >7%)

Trial outcomes

Primary outcomes

1

Resting Metabolic Rate

Resting metabolic rate (RMR) will be measured by indirect calorimetry using a computerized metabolic cart that provides valid and reliable measurement of oxygen consumption and carbon dioxide production - RMR can be estimated using formulas such as the Mifflin-St Jeor equation: Males: RMR = 10 \* weight (kg) + 6.25 \* height (cm) - 5 \* age (years) + 5 Females: RMR = 10 \* weight (kg) + 6.25 \* height (cm) - 5 \* age (years) - 161

Secondary outcomes

1

Glucose Tolerance Level

Glucose tolerance will be assessed using a standard 75-g oral glucose load to measure changes in glucose and insulin levels. Glucose tolerance will be defined as the 2-hour glucose level - a normal two-hour post-glucose level is below 140 mg/dL (7.8 mmol/L). Levels between 140 and 199 mg/dL (7.8 and 11 mmol/L) indicate impaired glucose tolerance (also called prediabetes), while levels of 200 mg/dL (11.1 mmol/L) or higher suggest diabetes.

Time frame
Baseline and Week 12
2

Expanded Short Physical Performance Battery (eSPPB)

Lower extremity function will be assessed using the eSPPB which measures balance, gait speed, and leg strength - Each component is scored separately, and then the scores are summed to give a total score ranging from 0 (worst) to 12 (best) - The total score is calculated by summing the scores from the three subtests. A higher total score indicates better lower extremity function, while a lower score indicates more functional limitations.

Time frame
Baseline and Week 12

Other outcomes

1

Core body temperature

Core body temperature will be measured continuously using a temperature monitoring patch worn on the chest.

Time frame
Baseline and Week 12
2

Lipid levels

Plasma levels of total cholesterol, VLDL cholesterol, HDL cholesterol, and triglycerides will be measured in fasted blood samples.

Time frame
Baseline, Week 4, and Week 12
3

Depressive Symptoms: 15-item Geriatric Depression Scale (GDS-15)

Questionnaire used to measure depressive symptoms in the elderly; ranges from 0-15 with higher scores indicating greater severity of depression; score of 0-4 is within normal range; score of 5-8 mild depression; score of 9-11 moderate depression; score of 12-15 severe depression

Time frame
Baseline and Week 12
4

Quality of Life: Medical Outcomes Study Short Form 36 (SF-36)

Quality of life questionnaire with a score that ranges from 0 to 100 with higher scores indicating better quality of life.

Time frame
Baseline and Week 12
