Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Tadalafil | Subjects will be randomized to one of two arms. 100 obese adult subjects will be randomized to the Tadalafil arm following the screening visit. Beginning at their baseline visit, they will receive an oral daily dose of Tadalafil (20mg) that they will take for 12 weeks (through their completion of the study). After randomization has occurred, the active comparator subjects will undergo the following visit protocol: baseline visit (two half-days), an interim visit (6 weeks post-baseline), and a 12-week visit (two half-days).~Tadalafil: Tadalafil is an FDA approved, clinically-available drug that inhibits the enzyme phosphodiesterase type 5A (PDE5). Subjects who are randomized to this arm will be provided with 20mg of Tadalafil to take every day for 12 weeks, beginning at their baseline visit. | 0 | 61 | EG000 |
| Group 2 | Placebo | Subjects will be randomized to one of two arms. 100 obese adult subjects will be randomized to the placebo arm following the screening visit. Beginning at their baseline visit, they will receive an oral daily dose of a placebo pill (20mg) that they will take for 12 weeks (through their completion of the study). After randomization has occurred, the placebo comparator subjects will undergo the following visit protocol: baseline visit (two half-days), an interim visit (6 weeks post-baseline), and a 12-week visit (two half-days).~Placebo: 100 patients will be randomized to receive a placebo pill. Subjects in this arm will be provided with 20mg Placebo to take every day for 12 weeks, beginning at their baseline visit. | 0 | 64 | EG001 |
