Evaluation of Obex® in Overweight and Obesity
October 20, 2021 updated by: Catalysis SL
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Obex
a nutritional supplement Obex® 8 g daily by oral route divided into two doses of 4g (between 15 and 20 minutes before lunch and dinner) diluted in water or juice for 6 months.
Patients will be recommended to comply with a healthy lifestyle through diet and exercise.
|
After concluded the six months of treatment, patients will be follow-up during six months without consumption of Obex
|
Placebo Comparator: Placebo
Placebo 8 g daily by oral route divided into two doses of 4g (between 15 and 20 minutes before lunch and dinner) diluted in water or juice for 6 months.
Patients will be recommended to comply with a healthy lifestyle through diet and exercise.
|
After concluded the six months of treatment, patients will be follow-up during six months without consumption of the placebo.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Body Weight.
Time Frame: Six months
|

Body weight measured in kilograms (k).
|
Six months
|
Change From Baseline in Waist Circumference at Week 24.
Time Frame: Six months
|
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).
|
Six months
|
To evaluate the effect of Obex® on fasting glucose levels.
Time Frame: Six months
|
The primary outcome is to evaluate the effect of the treatment with Obex® on fasting glucose levels by blood analysis.
|
Six months
|
