Cost-utility and Biological Underpinnings of MBSR in Fibromyalgia Syndrome
A Phase 3 study testing MBSR, FibroQol and TAU in people with Fibromyalgia Syndrome, run by Fundació Sant Joan de Déu at 1 site in Spain.
Trial summary
Purpose: Fibromyalgia syndrome (FMS) is a disabling condition mainly characterized by chronic widespread pain, disturbed sleep, fatigue, and distress. The estimated overall prevalence of FMS in Europe is 2.9% and it incurs in high personal, social and healthcare costs. Read more about this study

About this study
Official title: Cost-utility and Biological Underpinnings of Mindfulness-Based Stress Reduction (MBSR) in Fibromyalgia Syndrome: A Three-arm Randomized, Controlled Trial (EUDAIMON Project)
Purpose:
Fibromyalgia syndrome (FMS) is a disabling condition mainly characterized by chronic widespread pain, disturbed sleep, fatigue, and distress. The estimated overall prevalence of FMS in Europe is 2.9% and it incurs in high personal, social and healthcare costs. Available treatments in FMS are not curative and there is some evidence of positive effects of mindfulness-based stress reduction (MBSR) in patients with chronic pain and FMS. Nevertheless, although promising, the positive findings obtained in previous studies implementing mindfulness-based interventions in patients with FMS have to be interpreted with caution due to important methodological limitations (e.g. absence of randomization, high attrition rates, or small sample sizes). Therefore, further research in larger studies using more adequate methodologies is warranted. Furthermore, little is known about putative neurobiological processes underpinning the effects of mindfulness training in patients with chronic pain.

Aims: The aim of this randomized, controlled trial (RCT) is two-fold: firstly, to assess the effectiveness and cost-utility of MBSR added to treatment as usual (TAU); and secondly, to evaluate the effects of the compared interventions on neurobiological parameters. Specifically, MBSR will be compared to an active control which was previously reported as a cost-effective intervention (TAU + FibroQol psycho-educational program; Luciano et al., 2013) and also vs. TAU alone (in a 12-month follow-up RCT). Brain structure and function of pain-relevant areas and levels of inflammation markers (cytokines) will be assessed pre-post interventions in half of the study participants.
Methods:
Design: RCT with three arms:
- TAU + MBSR,
- TAU + FibroQoL and
- TAU.
Sample: 180 adults with FMS according to the ACR 1990 criteria (N=60 for each study arm) will be recruited from from the Parc Sanitari Sant Joan de Déu Rheumatology Service, Sant Boi de Llobregat, Spain. Half of the participants will be randomly selected to participate in the neurobiological pre-post evaluation (N= 30 each group). All patients will be assessed at baseline, post-intervention and 12-month follow-up for clinical variables, prep-post intervention for biomarkers study, and baseline and 12-month follow-up for cost-related variables.

Also called Usual care
In Spain the treatment as usual provided in FMS is mainly pharmacological and adjusted to the symptomatic profile of the patient. Counselling about aerobic exercise adjusted to patients' physical limitations is usually also provided.

Clinical summary

Nevertheless, although promising, the positive findings obtained in previous studies implementing mindfulness-based interventions in patients with FMS have to be interpreted with caution due to important methodological limitations (e.g. absence of randomization, high attrition rates, or small sample sizes). Therefore, further research in larger studies using more adequate methodologies is warranted. Furthermore, little is known about putative neurobiological processes underpinning the effects of mindfulness training in patients with chronic pain.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing MBSR, FibroQol and TAU in people with Fibromyalgia Syndrome, run by Fundació Sant Joan de Déu at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 14 Oct 2019. 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 Spain. 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. 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?
Effectiveness Evaluation: Revised Fibromyalgia Impact Questionnaire (FIQR) (time frame: Change from baseline scores at 12 months). The study lists 6 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 NCT02561416, which also lists 3 linked publications.
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 14 Oct 2019.
