This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether taking a daily oil rich in linoleic acid (a type of omega-6 fat) for 8 weeks can improve insulin resistance in adults aged 20-60 who have this condition plus at least one other cardiometabolic risk factor (like abdominal obesity or high blood pressure). Participants will be randomly assigned to receive either the linoleic acid oil or a control blended oil, while keeping their usual diet. The main goal is to see if the oil reduces insulin resistance, which could help manage metabolic disease.

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 120 people

The number the study aims to enrol. It can still change while the study runs.

Started

May 2025

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Men and women aged 20 to 60 years. * Insulin resistance (HOMA-IR \> 2.6). * At least one cardiometabolic risk factor: abdominal obesity (waist circumference \> 90 cm in men or \> 80 cm in women); low HDL-cholesterol (\< 40 mg/dL in men or \< 50 mg/dL in women); elevated LDL-cholesterol (\> 70 / 100 / 130 mg/dL, according to estimated cardiovascular risk); or elevated blood pressure (≥ 130/85 mmHg). Exclusion Criteria: * Diabetes diagnosis. * Severe psychiatric illness. * Malabsorption disorders or previous bariatric surgery. * Pregnancy or lactation. * Previous clinical cardiovascular disease. * Regular use of medications that could influence study outcomes, including: lipid-lowering agents insulin sensitizers antihypertensive drugs anticoagulants antiretroviral therapy thyroid hormones oral corticosteroids immunosuppressants polyunsaturated fatty acid (PUFA) supplements. * Fasting serum triglycerides ≥ 500 mg/dL or LDL-cholesterol ≥ 190 mg/dL. * Body mass index (BMI) ≥ 35 kg/m². * Very high blood pressure. * Any additional condition that may limit adherence to the study.
