Study summary

This randomized controlled trial evaluates the efficacy of three weekly GLP-1 receptor agonists (dulaglutide, semaglutide, and tirzepatide) in non-diabetic obese adults. 150 participants with BMI >30 will be randomized into three groups and followed for 6 months to assess changes in weight, BMI, lipid profile, and liver functions.

Read the detailed description

This is a single-center, randomized controlled trial planned at Al-Zafer Hospital, Najran, KSA.

150 non-diabetic obese participants (BMI >30, age >18) will be randomized into three equal groups: Group 1: Dulaglutide 1.5 mg weekly Group 2: Semaglutide 1.0 mg weekly Group 3: Tirzepatide 5 mg weekly, titrated as tolerated

Participants will be assessed at baseline, 3 months, and 6 months for weight, BMI, waist circumference, fasting glucose, lipid profile, and liver enzymes. Monthly follow-up will ensure medication adherence and monitor gastrointestinal adverse events.

Inclusion: BMI >30, age >18, non-diabetic. Exclusion: Diabetes, liver disease, renal dysfunction, pancreatic disease, thyroid disease, psychological disorders, pregnancy.

Inclusion criteria

  • Subjects (above 18 years old) obese (BMI) above 30

Exclusion criteria

Exclusion Criteria:

  • Subjects with liver disease, renal dysfunction diabetes, pancreatic diseases ,thyroid disorder or goiter psychological diseases like depression and pregnant women, and Patients who will refuse
Terms in these criteria, in plain language(1)

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.

BMI (body mass index)

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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2025 to primary completion in Apr 2026, 4 months.

Of 63 non-industry phase 3 interventional studies under Obesity, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 56. This study's 4 months is below that.

Counting every sponsor, half of 262 studies reached it within 24 months; a quarter within 18 and three quarters within 34.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
