Study summary

Gout, the most common inflammatory rheumatism in France, is a complication of chronic hyperuricemia (> 360umol / l). The resulting urate crystals are deposited in many tissues, especially the skeletal or kidneys. It appears in the form of spontaneously regressive inflammatory joint attacks in 5 to 7 days but recurrent. Gout turns into a chronic disease if uric acidemia is not reduced, and is responsible for joint destruction. It becomes a vector of renal failure and is associated with cardiovascular morbidity and a reduction in life expectancy. It is cured if a long-term treatment such as febuxostat leading to the normalization of the uric acidemia is administered.

However, the frequency of this disease is increasing in industrialized or emerging countries. The causes are numerous, particularly food, but also related to flaws in therapeutic care. Studies show that this treatment is not taken in particular because, after the acute attack, the patient who has become asymptomatic again no longer consults. Currently, in a traditional way and according to European recommendations, it is not prescribed until several weeks after the acute attack in order to avoid early relapses, which would then be more numerous. Nevertheless, even if the hypouricemic agent is prescribed late , the attacks can be repeated and become rare for several months after obtaining a uricemia below 360umol / l; they eventually disappear. Lack of knowledge of this disease largely affects the hazards of disease-modifying treatment, which alone can prevent the progression to chronic inflammatory disease and its cardiovascular and renal impact and on mortality. One of the causes of not taking a hypouricemic agent is its delayed administration.

This study is proposed to assess the relevance of early initiation versus delayed administration of such treatment.

Read the detailed description

This is a non-inferiority study comparing immediate administration with 6 weeks delayed administration of febuxostat at a dose of 80 mg / day. The methodology of non-inferiority is what we want to show. Indeed, the immediate initiation of a hypo-uricemic agent is currently considered as an aggravating factor with respect to the duration or the risks of early relapse of the crisis, without this being supported by precise studies. The basic treatment is beneficial in the long term: by normalizing uricemia, it controls gouty disease. We want to show that the early introduction is as well tolerated as its abstention which is the current recommendation.

The diagnosis of gout attack is based on recently established American-European criteria.

The choice of the hyporuricemic molecule is febuxostat, on the one hand because of a greater potency of action than allopurinol at the available dosages, which should make it possible to obtain a clear reduction in uraemia (of approximately 40%) and on the other hand easy to use - without dose adjustment - in patients with renal insufficiency with a creatinine clearance greater than 30 ml / min.

The number of patients participating in the study is set at 128, which is higher than the published prospective studies. Patients will be randomized (in order of succession when entering the study) into 2 groups, the first receiving febuxostat immediately for 6 weeks, the second receiving no immediate febuxostat treatment - which corresponds to current practice.

This study covers several periods:

  • the first, lasting 6 weeks, will allow a direct comparison of febuxostat with no DMARD: this is the primary objective.
  • the second is an extension phase and runs from the 7th to the 12th week where each patient in the context of routine care is treated with febuxostat: it makes it possible to compare the immediate use of the febuxostat (phase S0-S1 of the group 1) to its delayed administration (phase S6-S12 of group 2 with delayed administration) in terms of recurrence of gouty attacks.
  • the 3 ° of 3 months allows a later evaluation at 6 months of therapeutic maintenance.

The evaluations will take place at the end of the 2nd and 6th week (plus or minus 3 days) and at the end of the 3rd and 6th month (plus or minus one week).

They are carried out by an assessor who does not know the treatment of the patient.

They are based on the following parameters:

1- The number of days with gouty joint crisis, its location, reported by the patient in a booklet filled out daily: the occurrence of a new attack according to the criteria evaluated will also be collected.

2 - Assessment by the patient of his condition (pain, asthenia, walking, overall condition) by daily use of the VAS scale. Two functional indexes will be used and have been evaluated in gout -: the SF 36 Physical Dimension is filled during the 6 ° and 12 ° week visits: this index was chosen because it was not specific for a joint disease. and evaluate a period of 4 weeks; HAQ, developed for rheumatoid arthritis, evaluates a period of 2 weeks and provides a correct estimate of overall physical function (locomotor status) in tophaceae gout, less in the absence of tophus.

3 - Assessment by the doctor of the patient's clinical condition: joint and somatic examination: arthritis (yes or no), presence of tophi, arterial pressure, cardiovascular and skin examination.

4 - Collection of drug intolerances. 5 - At W6 and W12, biological examinations will be carried out, according to the recommendations: determination of uricemia, serum creatinine, transaminases, CRP and determination of the CBC-platelets which makes it possible to control the intake and the biological tolerance of the hypouricemic treatment, the level of biological inflammation.

The treatment of the crisis will respond to European recommendations and will be left to the doctor's free initiative. This treatment will be immediately followed by a preventive treatment for relapse at the recommended doses.

Febuxostat:

Its indication will not refer to European recommendations but to French recommendations: hypo-uricemic treatment is indicated as soon as the diagnosis of gout is retained. It will be delivered at the same time as the treatment of the crisis, within 5 days maximum following its diagnosis.

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
