About this study

Official title: Efficacy and Safety of the Obex® Nutritional Supplement in Overweight and Obese Subjects: Phase III.

  • Obesity is an important and growing worldwide
  • Obesity is highly related to the development of metabolic syndrome, diabetes, cardiovascular diseases and cancer
  • Diverse adverse events have been reported with the use of antiobesity drugs.
  • Several articles describe the beneficial effect of several specific components of the Obex® supplement on weight loss, in the reduction of waist circumference, suppression of appetite, decrease fasting glucose levels, improvement of insulin sensitivity and β cells function.
  • Therefore, the administration of Obex in overweight and obese patients could be an excellent strategy to induce weight loss and ameliorate the metabolic disturbances related to obesity and overweight.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Body Weight.

    Change in body weight from baseline (0) after six months of treatment (i.e., weight at six month minus weight at baseline 0). Body weight measured in kilograms (k).

    Measured: Six months

  2. Change From Baseline in Waist Circumference at Week 24.

    Change in waist circumference from baseline after six months of treatment (i.e., waist circumference at six month minus waist circumference at baseline 0). Waist measured in centimeters (cm).

    Measured: Six months

  3. To evaluate the effect of Obex® on fasting glucose levels.

    The primary outcome is to evaluate the effect of the treatment with Obex® on fasting glucose levels by blood analysis.

    Measured: Six months

Secondary outcomes (13)
  1. To evaluate the effect of Obex® on Body Mass Index (BMI).

    The BMI will be measured by Quételet index.

    Measured: Six months

  2. To evaluate the effect of Obex® on the waist and hip ratio.

    Waist and hip ratio will be measured according to the World Health Organisation's data gathering protocol.

    Measured: Six months

  3. To evaluate the effect of Obex® on the waist and height ratio.

    Waist and height ratio will be measured.

    Measured: Six months

  4. To evaluate the effect of Obex® on arterial blood pressures (BP).

    The arterial BP will be evaluated by the doctor.

    Measured: Six months

  5. To evaluate the effect of Obex® on fasting insulin levels.

    The insulin levels will be evaluated by blood analysis.

    Measured: Six months

  6. To evaluate the effect of Obex® on insulin resistance.

    Homeostasis model assessment-estimated insulin resistance (HOMA-IR), calculated from individual serum measures (fasting insulin x fasting glucose/22.5).

    Measured: Six months

  7. To evaluate the effect of Obex® on insulin sensitivity.

    The Quicki, Bennett and Raynaud insulin sensitivity indexes will be evaluated by QUICKI = [1/[log I0 + log G0], Bennett index (BEN) = 1/(log I0 x log G0), Raynaud index (RAY) = [40/I0]).

    Measured: Six months

  8. To evaluate the effect of Obex® on β-cell function.

    Homeostatic model assessment-beta cell (HOMA-β), calculated from individual serum measures (20 x fasting insulin (µU/mL)/fasting glucose (mmol/L)-3.5).

    Measured: Six months

  9. To evaluate the effect of Obex® on cholesterol.

    The cholesterol, triglyceride, HDL-c and LDL-c levels will be evaluated by blood analysis.

    Measured: Six months

  10. To evaluate the effect of Obex® on hepatic enzymes.

    The hepatic enzymes (Alanine aminotransferase, Aspartate aminotransferase, gamma-glutamyltransferase, Alkaline Phosphatase) will be evaluated by blood analysis.

    Measured: Six months

  11. To evaluate the effect of Obex® on creatinine and uric acid concentrations.

    The creatinine and uric acid levels will be evaluated by blood analysis.

    Measured: Six months

  12. To evaluate the effect of Obex® on haemoglobin levels.

    The haemoglobin levels will be evaluated by blood analysis.

    Measured: Six months

  13. To evaluate the effect of Obex® on Conicity Index (CI)

    CI will be measured by index.

    Measured: Six months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Obex in people with Overweight and Obesity, run by Catalysis SL at 1 site in Cuba.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Cuba. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Body Weight. (time frame: Six months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03541005, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Oct 2021.
