Can a pill tame diabetes and obesity together?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Active syphilis: positive treponemal antibody test and positive nontreponemal serological test (rapid plasma reagin \[RPR\] or toluidine red unheated serum test \[TRUST\]) at screening. * 5.Abnormal physical or laboratory examination findings 1. Clinically significant abnormal chest X-ray/chest computed tomography (CT) or ECG findings, including Fridericia-corrected QT interval (QTcF) \> 450 milliseconds (ms) for male subjects and \> 470 ms for female subjects; 2.
