Study of the Symptomatic Improvement in Patients With Fibromyalgia by Means of a Food Supplement

Completed

• Conditions: Fibromyalgia
• Interventions: Dietary Supplement: Food supplement

• Registration Number: NCT05718908
• Lead Sponsor: Arafarma Group, S.A.

Brief Summary

Fibromyalgia is a syndrome (set of symptoms) of unknown etiology and characterized by diffuse musculoskeletal pain and chronic fatigue. In addition, other symptoms such as cognitive alterations, sleep rhythm disturbances, psychiatric syndromes such as anxiety, depression, etc. Other very characteristic symptoms are hyperalgesia (very low pain threshold) and allodynia (amplified response to painful stimuli).

The treatment of fibromyalgia is symptomatic and the drugs only serve to reduce symptoms in some patients, in addition to the fact that these available treatments (antidepressants, pain signal modulators, rescue analgesics, etc.) have many side effects.

The food supplement which is the object of this study, FibrofixPlus®, is made up of a combination of natural substances.

This is the reason why this observational study aims to improve symptoms caused by fibromyalgia in patients treated with FibrofixPlus®.

Detailed Description

Patients who meet the fibromyalgia criteria according to the definition of the American College of Rheumatology (ACR) in 1990 and 2010, with a minimum score of 4 on the Visual Analogue Scale (VAS) of Fatigue and Pain and without any treatment (anxiolytics, neuroleptics, antidepressants and/or narcotic analgesics) in a minimum of 4 weeks prior to the beginning of the study, with some exceptions, and who do not meet any of the exclusion criteria will be invited to participate in the study.

There are three study visits which are distributed throughout 8 weeks.

Arm && Interventions

Group	Intervention	Description
Fibromyalgia patients	Food supplement	All patients will be administered with one sachet of food supplement (FibrofixPlus®) per day, for 8 weeks.

Primary Outcome Measures

Name	Time	Method
Symptomatic change of fibromyalgia through the Fibromyalgia Impact Questionnaire (s-FIQ), after taking the FibrofixPlus® food supplement, for 8 weeks.	From Visit 0, and at each visit (Visit 1 or 4 weeks after Visit 0; and Visit 2 or 8 weeks after Visit 0).	To assess the magnitude of the symptomatic improvement by measuring the results to questions of the Fibromyalgia Impact Questionnaire (s-FIQ). This questionnaire scores from 0 to 100, being 0 the best quality of life and functional capacity, and 100 is the worst result.

Secondary Outcome Measures

Name	Time	Method
Change of pain symptom through the Widespread Pain Index (WPI).	From Visit 0, and at each visit (Visit 1 or 4 weeks after Visit 0; and Visit 2 or 8 weeks after Visit 0).	To assess the pain symptom by the completion of the Widespread Pain Index (WPI).; The WPI scores from 0 to 19, being the highest result the worst outcome as defined by the number of body areas with pain.
Change of pain symptom through the Symptom Severity Score (SS Score).	From Visit 0, and at each visit (Visit 1 or 4 weeks after Visit 0; and Visit 2 or 8 weeks after Visit 0).	To assess the pain symptom by the completion of the Symptom Severity Score (SS Score).; The SS Score has a scoring from 0 to 12, being 0 the best outcome and 12 the worst outcome.
Change of the sleep quality through the Pittsburgh Sleep Quality Index (PSQI).	From Visit 0, and at each visit (Visit 1 or 4 weeks after Visit 0; and Visit 2 or 8 weeks after Visit 0).	To assess the sleep quality by the completion of the Pittsburgh Sleep Quality Index (PSQI).; The PSQI has a scoring from 0 to 21, being 0 the best outcome with no difficulties to sleep.
Rate of safety episodes.	Visit 1 to Visit 2, up to 4 weeks.	All episodes will be recorded, whether considered minor or serious, food supplement-related or not.
Change of the sleep quality through the Symptom Severity Score (SS Score).	From Visit 0, and at each visit (Visit 1 or 4 weeks after Visit 0; and Visit 2 or 8 weeks after Visit 0).	To assess the sleep quality by the completion of the Symptom Severity Score (SS Score).; The SS Score has a scoring from 0 to 12, being 0 the best outcome and 12 the worst outcome.
Change on the quality of life through the questionnaire Short Form-36.	At Visit 0 and at Visit 2, or 8 weeks after Visit 0.	To assess the quality of life by the completion of the Short Form-36 Questionnaire (SF-36).; The SF-36 has several questions so when the scoring is higher, better is the health status.
