Brief Summary

This study aims to test whether a multi-disciplinary intervention involving exercise and nutrition can slow down the decline in physical function, muscle strength and mass in older adults (aged 65-75) with Type 2 diabetes (T2D) and obesity treated with Semaglutide.

The main questions it aims to answer are:

In older people with T2D and obesity, treated with Semaglutide, does a multi-disciplinary intervention of exercise and nutrition compared to standard health recommendations:

1. Reduce the rate of decline in muscle mass?

2. Reduce the rate of decline in muscle strength?

3. Reduce the rate of decline in physical function?

Participants will:

Administer Semaglutide once weekly for 6 months. Visit the clinic once every 8 weeks for checkups and tests. Keep a diary of their exercise and food consumption. Participants in the intervention group will participate in an online exercise program and will receive personal nutritional counseling.

Detailed Description

The study will be conducted at the Center for Successful Aging with Diabetes, Sheba Medical Center and the Clinical Research Center for Diabetes, Hadassah Medical Center, Israel. The research will include a team with expertise in endocrinology, nutritional interventions, physical therapy, fitness training, medical imaging and biostatistics.

Participants aged 65-75 years, with both type 2 diabetes (T2D) and overweight / obesity, will be randomly allocated to either a (1) Semaglutide and multi-disciplinary intervention group (MDIG) comprised of exercise and diet or (2) Semaglutide and general health recommendations control group (GHRG). The drug dosage (Wegovy, Semaglutide) will be gradually increased every 4 weeks starting with 0.25 milligrams (mg) on week 0 and reaching 2.4 mg by week 16 as per the Wegovy label and maintained at 2.4 mg until the end of the trial (week 26). If a participant is unable to tolerate the 2.4 mg subcutaneous weekly dose (SC QW) of Semaglutide, the highest tolerable dose will be administered, with continued efforts to gradually increase the dose over time.

Participants in the MDIG will undergo a once-weekly group exercise training that will be delivered online, followed by 2 unsupervised home-based sessions. Weekly phone calls and a personal exercise diary will be used in order to measure adherence to the exercise program. In addition, personal nutritional counseling will be administered by a certified dietitian every 2 weeks for the first 4 weeks and every 4 weeks for the remaining 22 weeks via a virtual meeting platform (i.e., "ZOOM"). In addition, a 2-day food diary will be filled out for tracking and documentation. All group exercise training will be conducted via a virtual meeting platform as well. Participants allocated to the GHRG will receive general health recommendations both verbally and in writing and continue with their regular daily routine. They will also be required to complete a personal exercise and food diary.

Visit 1- screening: All potential eligible subjects will be invited for a screening Visit, during which the following information would be obtained: a) Informed consent; b) Eligibility criteria form; c) Physician interview and examination; d) Demographic and medical information; e) Medical History and recent blood work.

Visits 2 - 5: After being allocated to the two study arms, 4 additional measurement visits will be booked: (1) baseline - week 0 (visit 2), (2) week 8 (visit 3), (3) week 16 (visit 4), and (4) end of treatment - week 26 (visit 5). The following information will be collected on each visit: a) Anthropometric measurements, including waist and hip circumference, waist to hip ratio, weight, height and body mass index (BMI, calculated in kg/m2); b) Body composition measured with Magnetic Resonance Imaging (MRI) and Dual-energy X-ray Absorptiometry (DXA); c) Functional and strength assessments, including balance, aerobic capacity, gait speed and strength tests d) Blood pressure (BP) and heart rate (HR) e) lipid profile and hemoglobin A1C test (HbA1C) (only on visits 2 and 5); f) frailty assessment (only on visits 2 and 5); g) Distribution of Semaglutide, usage and titration guidance (only visits 2-4) ; h) Documentation of 2-day self-reported food diary for MDIG (only on visits 3-5) i) Nutritional counseling for MDIG; j)collection and recording of partly used and full pens for estimation of Semaglutide adherence (only on visits 3-5); k) Documentation of exercise adherence through self-reported exercise diary (only on visits 3-5); l) Target Physical Examination; m) Adverse events collection (only on visits 3-5). All baseline measurements will be conducted within one week before the trial commences.

Measures of compliance/adherence: Compliance to the drug would be monitored in both arms. Consumption of <80% or >120% of study background medication (Semaglutide) would be considered poor adherence to therapy. Patients will be instructed to bring back all empty, partly used and full Semaglutide pens at each site visit and all pens will be counted and estimation of Semaglutide adherent will be recorded. In the MDIG, the subject's adherence to the exercise regimen will be assessed during weekly phone calls based on subject reporting and by documentation in a personal diary they will bring to each visit. Good compliance/adherence would be considered as performing ≥ 2 of the exercise sessions. In order to perform a protein consumption evaluation, the nutritional sessions will be recorded, and the patients will be asked to fill out a 2-day food diary before each visit.

Glucagon-like Peptide-1 Receptor Agonist (GLP-1-RA) treatment: All patients will receive Semaglutide 2.4 mg once a week for 26 weeks. Semaglutide will start at 0.25 mg per week and escalate in a fixed-dose regimen every 4 weeks until the target dose is reached (i.e., 2.4 mg by week 16 until the end of trial). If a participant will not be able to tolerate Semaglutide 2.4 mg SC QW dose, the highest tolerable dose of Semaglutide will be used and further attempts to increase Semaglutide dose will continue.

Changes in body composition will be carried out using whole-body MRI, DXA and body composition measures.

Functional assessments will include the following tests:

1. Timed up and Go (TUG) test which examines dynamic balance and mobility skills. The participant is asked to get up from a chair with handles, walk three meters, turn, walk back, and sit down in the shortest possible time. Data suggests that the TUG test is a reliable and valid test for quantifying functional mobility and risk for falls that may also be useful in following clinical change over time.

2. Short Physical Performance Battery (SPPB): The SPPB is an objective assessment tool for evaluating three domains of lower extremity physical function in older adults: balance, repeated chair stands, and gait speed. It is associated with various adverse health outcomes in older adults, including mobility impairments, difficulties performing basic activities of daily living (ADL) or instrumental activities of daily living (IADL), and falls. Poor performance on the SPPB and its components independently predict higher fall risk over 1 and 4 years of follow-up.

3. The 6-minute walk test (6MWT). The 6MWT assesses aerobic capacity. The test measures the distance walked over six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. The 6MWT has been linked to frailty and mortality in older adults.

4.10-meter walk (10MW): The 10MW determines gait speed. The participant is asked to walk at a "comfortable pace" for 14 meters. The score achieved is determined by the walking time of the central 10 meters. Studies have shown that better gait speed is associated with a lower risk for functional decline, hospitalization and mortality.

Strength tests:

1. 30 second chair stand (STS): The purpose of this test is to evaluate lower limb muscle strength. The instructions are to get up from sitting to standing as many times as possible without the assistance of the arms for 30 seconds. The number of times within 30 seconds that the participant succeeds to rise from a seated position is counted. The strength of the lower limb muscles has a crucial impact on daily function. Failure to perform STS movements efficiently and smoothly may lead to falls.

2. Hand grip strength test: The maximum grip strength test evaluates upper limb strength using the Jamar dynamometer. The test is conducted in a neutral hand position and repeated 3 times. Grip strength assessment has been shown to have predictive validity and low values are associated with falls, disability, impaired health-related quality of life and prolonged length of stay in hospital as well as increased mortality.

Screening for frailty will be performed using the Fried scale. The scale includes five criteria, and pre-frailty is defined as the presence of two components while frailty is defined as the presence of at least three of the following components: (1) unintentional weight loss - loss of 10 lbs/4.5 kg or more in 1 year; (2) self-reported exhaustion / fatigue; (3) low physical activity level as assessed by a modified Baecke questionnaire; (4) slow gait speed - less than 0.8 m/s with or without a walking aid; (5) low grip strength relative to gender and body weight.

Anthropometric measurements: Weight and height, with body mass index (BMI) calculated as kg/m2 and waist and hip circumference measured, and waist to hip ratio calculated.

Glycemic control (GC): Hba1c will be collected at baseline and at the end of trial.

Socio-demographic questionnaire: Socio-demographic characteristics, including age, gender, education, marital status, employment status, ethnicity, and smoking status, will be collected at visit 1.

Discontinuation: Participants may withdraw consent for any reason at any time or be discontinued from the trial by the investigator if, based upon his clinical judgment, continuation in the trial is deemed inappropriate. In addition, the investigator may discontinue a subject if enrollment into the trial is inappropriate, the trial plan is violated, or for administrative and/or any other safety reasons or if the trial is terminated early for any reason.
