Study summary

The prevalence of obesity in Mexico is 35.4%, and it is considered a risk factor for the development of diabetes, systemic arterial hypertension and dyslipidemia. Obesity due to the increased distribution and growth of adipose tissue creates a pro-inflammatory state induced by molecules secreted by the adipocytes themselves. Netrin-1 is a cell migration protein, which directs the recruitment, migration and entrapment of macrophages in different tissues, within adipose tissue the entrapment of macrophages induces the release of pro-inflammatory cytokines, which increase the secretion of pro-inflammatory adipokines. It has been found in high concentration in patients with obesity, insulin resistance and type 2 diabetes. Thymol is a phytopharmaceutical derived from oregano oil that has shown powerful anti-inflammatory and antioxidant effects through the stimulation of PPAR-gamma, adiponectin and inhibition of the NF-κB pathway mediated by the JNK pathway, pathways in which netrin-1 is involved in macrophage entrapment and recruitment.

Read the detailed description

Objective: To evaluate the effect of thymol administration on the serum concentration of netrin-1 in obese subjects.

Material and methods: this is a randomized, double-blind, placebo-controlled clinical trial design.

Inclusion criteria:

    • Subjects between 18 and 35 years old.
    • Subjects with BMI ≥ 30.0 and ≤35.0.
    • Subjects with systolic blood pressure less than 135 mmHg.
    • Subjects with diastolic blood pressure less than 85 mmHg.
    • Voluntary acceptance and signing of the informed consent. These patients will be randomly assigned to two groups, one will have the intervention with thymol 200 mg every 8 hours for 90 days while the other will have placebo with Mg 200 mg every 8 hours for 90 days.

Statistical analysis: quantitative variables: means and standard deviation. Qualitative variables: frequencies and percentages. In the comparison according to the serum level of netrin-1 between the two groups after the intervention: t student for quantitative variables, Chi square for qualitative variables. Statistical significance p equal to or less than 0.05.

Terms in these criteria, in plain language(3)

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.

GFR and eGFR (kidney filtering)

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.

Contraception

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.

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

Started Apr 2022 (actual). Primary completion is estimated for Dec 2022, 8 months after the start.

Of 132 non-industry phase 2 interventional studies under Obesity, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 57. This study's planned 8 months is below that.

Counting every sponsor, half of 308 studies reached it within 16 months; a quarter within 10 and three quarters within 35.

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 Jun 22, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
