Descriptive Information
Brief TitleAn Observational, Retrospective, Multicenter, National Study for the Monitoring of Subjects Who Participated in the LoadET Clinical Trial
Official TitleRetrospective, Multicentric, National, Observational Study, to Follow-up the Patients Who Participated in the Loadet Study (RELOADET Study)
Brief Summary

Previous studies suggest that an increase in doses of weekly etanercept from 50 mg to 100 mg improves the efficacy of the treatment in patients with cutaneous psoriasis, rheumatoid arthritis, and psoriatic arthritis. In this same line of study, during the 2007 2008 period, we conducted a multicenter, double-blind, 12-week Study (LoadET, 0881A3-102090) comparing the efficacy of etanercept at a standard dose (50 mg/week) versus a double dose (100 mg/week) in subjects with AS refractory to conventional therapy. The interim results of said study do not appear to support the value of doubling the dose of etanercept in the treatment of subjects with AS. Once this study was finalised, the subjects continued to be monitored by their regular physician, who decided on the dose and treatment to follow according to the conditions of standard clinical practice.

The objective of this observational study is to evaluate the course of the disease in the long-term (three years) under the conditions of standard clinical practice, in subjects who had participated in the LoadET study. Therefore, we would like to follow-up on those patients by reviewing their clinical histories for the three-year period between the finalisation of their participation in the LoadET Study (0881A3-102090) and now. This will allow us to assess the efficacy and survival of the drug, as well as the possible appearance of side effects in the three years following the finalisation of the study by comparing the results according to if the subjects had received 50 mg/week or 100 mg/week during the LoadET study (0881A3 102090).

Detailed DescriptionGiven that this is a follow-up study of subjects who participated in the LoadET study (0881A3-102090), we have planned the inclusion of all subjects who completed said study, that is, 97 of the 108 subjects in the LoadET study.
Study TypeObservational
Study DesignObservational Model: Cohort
Time Perspective: Retrospective
Target Follow-Up DurationNot Provided
BiospecimenNot Provided
Sampling MethodNon-Probability Sample
Study PopulationAnkylosing Spondylitis subjects who were treated with ETN when participating in the previous LoadET study (0881A3-102090)
ConditionAnkylosing Spondylitis
InterventionDrug: ETANERCEPT

During the LoadET study (0881A3-102090), subjects were treated with etanercept 100 mg versus 50 mg weekly. After completing this study, the subjects were allowed to continue the treatment with etanercept 50 mg weekly, etanercept 100 mg weekly, another drug, or abandoned medication at the discretion of their physician.

This is a non-interventional study in which historic data will be collected retrospectively from the patient's clinical history. During the historical period covered in the Study, patients would have received the treatment and the medical care that their treating physicians considered appropriate under the conditions of standard clinical practice.
