What this study is about

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).

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Full registry criteria

Inclusion Criteria: * Age ≥18 years and ≤ 65 years old; * BMI ≥ 30 Kg/m2 and ≤45 kg/m2 * BMI from 27 kg/m2 to 30 Kg/m2 with at least one associated co-morbidity related to overweight \[e.g. dysglycemia (pre-diabetes and/or metabolic syndrome), hypertension, dyslipidemia, obstructive sleep apnea syndrome (OSAS\], or cardiovascular disease\] * Starting to use a GLP-1 RAs (liraglutide, semaglutide) or dual GIP and GLP-1 RAs (tirzepatide) for weight reduction; patient can be enrolled if they start the treatment at the time of enrollment or up to 2 weeks * Diet composition adjusted to provide 0.9-1.1 g/Kg ideal body weight proteins * Signed informed consent Exclusion Criteria: * Type I and Type II diabetes; patients with pre-diabetes and/or metabolic syndrome and assuming Metformin and SGLT-2 inhibitors can be enrolled * Monogenic obesity (Subjects with a known diagnosis of monogenic obesity, including but not limited to pathogenic mutations in LEP, LEPR, MC4R, POMC, PCSK1, or other genes known to cause monogenic forms of early-onset or syndromic obesity) * Reduced kidney function, defined as eGFR \< 60 mL/min/1.73 m², calculated using the CKD-EPI equation (see Appendix 1) * Oncologic patients in active treatments * Hypersensitivity to any of the constituents of the study product * Pregnancy * Breastfeeding * Use of meal replacements for a diet enriched with aminoacids and/or HMB * Use of food supplements containing aminoacids and/or HMB; patients can be included in the study if they undergo a washout period of at least 15 days

Treatments and study arms

Myosave®

Primary outcomes

Change in Appendicular Skeletal Muscle Mass (ASMM)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.
