Study Overview
Brief Summary
This study evaluates whether a Food for Special Medical Purposes (FSMP) can help to preserve appendicular skeletal muscle mass (ASMM) in adults undergoing weight loss treatment with GLP-1 receptor agonists or dual GIP/GLP-1 receptor agonists. Participants will receive the FSMP or a matching placebo for 24 weeks while continuing standard GLP-1-based therapy. ASMM will be measured using Bioelectrical Impedance Vector Analysis (BIVA).
Detailed Description
This randomized, double-blind, placebo-controlled investigates whether a Food for Special Medical Purposes (FSMP) can help preserve appendicular skeletal muscle mass (ASMM) in adults undergoing weight loss treatment with GLP-1 receptor agonists or dual GIP/GLP-1 receptor agonists.
Eligible participants are adults with obesity or overweight with comorbidities who are initiating GLP-1-based therapy as part of standard clinical management. Participants are randomized in a 1:1 ratio to receive either the FSMP or a matching placebo for 24 weeks, in addition to their ongoing GLP-1 RA or dual GIP/GLP-1 RA therapy. Study visits occur at baseline, 8 weeks, 16 weeks, and 24 weeks.
This trial aims to determine whether targeted nutritional support can mitigate the loss of lean mass commonly observed during pharmacologically assisted weight loss, thereby improving functional outcomes and overall patient well-being.

Arms & Interventions
Myosave®
Participants receive Myosave® twice daily (two sachets/day) for 24 weeks, in addition to standard GLP-1 RA or dual GIP/GLP-1 RA therapy.
Intervention: Myosave® (Dietary Supplement)
Placebo
Participants receive a matching placebo twice daily for 24 weeks, in addition to standard GLP-1 RA or dual GIP/GLP-1 RA therapy.
Intervention: Placebo (Other)
Outcomes
Primary Outcomes
Change in Appendicular Skeletal Muscle Mass (ASMM)
Time Frame: Baseline, Week 8, Week 16, Week 24
ASMM will be assessed using Bioelectrical Impedance Vector Analysis (BIVA). The primary endpoint is the change in ASMM from baseline to Week 24 to determine whether the Food for Special Medical Purposes (FSMP) preserves skeletal muscle mass compared with placebo.
Secondary Outcomes
- Handgrip Strength(Baseline, Week 8, Week 16, Week 24)
- Change in Fat-Free Mass (FFM)(Baseline, Week 8, Week 16, Week 24)
- Change in Fat Mass (FM)(Baseline, Week 8, Week 16, Week 24)
- Change in Health-Related Quality of Life (Short Form-36 Health Survey, SF-36)(Baseline, Week 8, Week 16, Week 24)
- Change in Body Weight (kg)(Baseline to Week 24)
