What this phase means
Phase 4: the treatment is already approved. This study asks new questions — longer-term effects, other diseases, or how it compares in everyday care.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Dual GIP/GLP-1 Receptor Agonist Tirzepatide, or Resistance Training. The registry lists allocation as randomized. Incretin-based pharmacotherapies induce significant weight loss and represent a paradigm shift in obesity treatment.
They plan to enroll about 150 people at München. Taking part typically means taking a study drug (or dummy pill), following a program (exercise, therapy, diet, or an app) plus check-ins.
Official title (unrewritten)
A Phase IV, Randomized Controlled Trial to Evaluate the Effects of Resistance Training Versus Usual Care on Thigh Muscle Volume During Treatment With the Dual GIP/GLP-1 Receptor Agonist Tirzepatide in Adults With Obesity
Interventions: Dual GIP/GLP-1 Receptor Agonist Tirzepatide, Resistance Training
Primary outcome (registry wording): Change in contractile thigh muscle volume (mL), as assessed by magnetic resonance imaging (MRI)
