What the trial is, and whether it could suit you
To characterize the impact of Isturisa on clinical features and comorbidities associated with MACS. The investigators hypothesize that patients treated with Isturisa will exhibit significantly better metabolic indicators (such as fasting glucose, HbA1c, and lipid profile), blood pressure, weight, body composition and bone mineral density than at Baseline. The investigators also assess the effect of Isturisa on quality of life and psychological symptoms in patients with MACS. The investigators hypothesize that treatment with Isturisa will lead to significant improvements in quality-of-life scores and reductions in depression scores compared to Baseline.
