Exclusion Criteria
Any current, recent use (past 4 weeks), or planned use of:
16. Female who is pregnant, breastfeeding, or intends to become pregnant or is of and not using a highly effective contraceptive method.
15. to GLP-1 receptor agonist therapy as per Tirzepatide (Zepbound ®) label, including a personal or family history of medullary thyroid carcinoma; a history or diagnosis of multiple endocrine neoplasia syndrome type 2; known to tirzepatide or any of its .
16. Currently enrolled in another clinical study involving an product or participated in one and received treatment (active or placebo) in the last 30 days.
17. Planned surgical procedures requiring general anesthesia or sedation during the study or within 2 weeks following the last dose of study drug.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Change in Vasomotor Symptoms Frequency
Change in the frequency of self-reported daily average vasomotor symptoms from baseline to 24 weeks. Vasomotor symptoms will be captured for 2 weeks at baseline and 2 weeks at the end of the study.
Time frame: Baseline, 24 weeks
Change in Vasomotor Symptom Severity
Change in self-reported daily vasomotor symptom severity from baseline to 24 weeks. Vasomotor symptoms will be captured for 2 weeks at baseline and at the end of the study. Severity will be classified as follows: Mild, sensation of heat without sweating/dampness; Moderate: sensation of heat with sweating/dampness, but able to continue current activity. May briefly fan yourself; Severe: sensation of intense heat with sweating causing disruption of current activity.
Time frame: Baseline, 24 weeks
Aging Biomarkers: Cellular Senescence Markers in Plasma
Cellular senescence markers are measured in plasma samples to assess biological aging and cellular stress. These markers may include proteins associated with the senescence-associated secretory phenotype (SASP). Quantification is performed using immunoassays. Higher levels of senescence markers indicate increased cellular senescence.
Time frame: 24 weeks
Difference between biological and chronological age
Epigenetic clocks estimate biological age by analyzing DNA methylation patterns at specific CpG sites across the genome. Biological age estimates are compared to chronological age to assess aging acceleration or deceleration. Biological age greater than chronological age indicates accelerated biological aging and potential increased risk of morbidity and mortality. Primary measure is the difference (ΔAge) between biological and chronological ages = reported in years.
Time frame: 24 weeks
Change in Reactive hyperemic index
Vascular function will be measured using the EndoPAT device to assesses reactive hyperemia index (RHI) from baseline to week 24 on treatment or placebo. RHI is automatically calculated through a computer algorithm by following the equation: \[(tested arm-post occlusion/tested arm-baseline)/(control arm-post occlusion/control arm-baseline)\] × baseline correction factor. Endothelial dysfunction is defined as having an RHI ratio of equal or less than 1.67.
Time frame: Baseline, 12 weeks and 24 weeks
Change in Augmentation Index percentage
Augmentation Index (AIx): AIX uses applanation tonometry of the radial artery pulse, calibrated to resting brachial systolic and diastolic pressures (SphygmoCor XCEL, Medtronic, Minneapolis, MN). Aortic systolic, diastolic, and pulse pressures will be derived from a synthesized aortic waveform using a validated mathematical transfer function. Augmentation pressure, reflecting the difference between aortic systolic pressure and the inflection point caused by the reflected wave, is influenced by arterial stiffness as well as factors like heart rate and ejection dynamics. AIx is calculated as augmentation pressure divided by aortic pulse pressure × 100%, adjusted to a heart rate of 75 bpm (AIx@75 bpm). Measurements will be performed in duplicate and averaged.
Time frame: Baseline, 12 weeks, and 24 weeks
Change in Pulse Wave Velocity
SphygmoCor estimates central arterial stiffness by calculating the speed at which the pressure wave travels between the carotid and femoral arteries using applanation tonometry and reported as the pulse wave velocity (PWV); PWV m/s
Time frame: Baseline, 12 weeks, and 24 weeks
Change in Cardiometabolic Parameters: Blood Pressure
Change in cardiometabolic parameters including blood pressure from baseline to week 24 on treatment or placebo. Measured in mmhg
Time frame: Baseline, 24 weeks
Change in Cardiometabolic Parameters: Fasting Glucose
Change in cardiometabolic parameters including fasting glucose from baseline to week 24 on treatment or placebo. Measured in mg/dL
Time frame: Baseline, 24 weeks
Changes in Cardiometabolic Parameters: HbA1C
Change in cardiometabolic parameters including HbA1C from baseline to week 24 on treatment or placebo. Measured in %
Time frame: Baseline, 24 weeks
Changes in Cardiometabolic Parameters: Lipoprotein profile

Time frame: Baseline, 24 weeks
Changes in Cardiometabolic Parameters: hsCRP
Change in cardiometabolic parameters including hsCRP from baseline to week 24 on treatment or placebo. Measured in mg/L
Time frame: Baseline, 24 weeks
Change in Physical Function Measure: Short Physical Performance Battery (SPPB) score.
The SPPB is a standardized test that evaluates lower extremity function using three components: balance tests (standing in various positions), gait speed (walking a short distance), and chair stand (repeated standing from a seated position). Each component is scored from 0 to 4; the total score ranges from 0 to 12. Higher scores represent better physical function
Time frame: Baseline, 24 weeks
Change in Physical Function Measure: Modified Clinical Test of Sensory Interaction in Balance (mCTSIB) performed on the Rehabilitation Artificial Physical Intelligence Database (RAPID) foot pressure mat
The mCTSIB assesses balance under four sensory conditions: eyes open/closed on firm and foam surfaces. Testing is performed while standing on the RAPID foot pressure mat, which captures center of pressure and postural sway data. The primary measure is average sway area of the four sensory conditions. The sway area is the area which is required to correct equilibrium, representing the total area covered by postural sway, measured in square centimeters (cm²).
Time frame: Baseline, 24 weeks
Change in Physical Function Measure: Standing Chest Throw Test with a 2-kg Weighted Ball using Motion Sensor Technology (MST)
This test evaluates upper body muscular power. Participants perform a two-handed chest throw of a 2-kg medicine ball from a standing position. The MST is used to record throw distance, velocity, and related performance metrics. The primary measure is Peak Power Score (W).
Time frame: Baseline, 24 weeks
Change in Physical Function Measure: Chair-to-Stand Tests using Motion Sensor Technology (MST)
This test assesses lower body strength and function. Participants are instructed to stand up from a chair and sit back down five times without using their arms. The MST measures movement dynamics. The primary measure is peak power score (W).
Time frame: Baseline, 24 weeks
Change in Physical Function Measure: Six-Minute Walk Test (6MWT)
The 6MWT is a standardized submaximal exercise test used to assess functional aerobic capacity. Participants are instructed to walk as far as possible in six minutes along a flat, straight course. The total distance walked is recorded in feet. Longer walking distances indicate better aerobic capacity and endurance.
Time frame: Baseline, 24 weeks
Change in Physical Function Measure: Hand Grip Strength using a Hydraulic Hand Dynamometer
Participants are instructed to squeeze the dynamometer with maximum effort, measured in kilograms. The highest value from multiple trials is recorded.
Time frame: Baseline, 24 weeks
