Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 75 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • All participants who were allocated to the study all had a history of taking tolerable and adequate dose of urate lowering therapy including febuxostat 40-80mg daily or allopurinol 200-300 mg daily for at least 4 weeks and were defined as difficult to treat or refractory gout patients. All patients had a negative of rheumatoid factor and antinuclear antibody, Hb>100g/L, total leukocyte count≥3.5×109, PLT≥80×109, serum creatinine<133umol/L, transaminases<60U/L and fasting urate≥6.0mg/dL.
  • Inclusion criteria for the gouty patients were age≥18 years old, BMI(18-30kg/m2). All participants enrolled in our study fulfilled American College of Rheumatology criteria for primary gout.

Who cannot join

  • Exclusion criteria included secondary gout (because it is always associated with some underlying renal disease), a history of congestive heart failure, serum creatinine≥133umol/L (because the patients have underlying risks if NSAID needed) or the use of glucocorticoid>15mg daily,colchicine, uricosuric drugs, chemotherapy or immunosuppressive therapy in the past three months.

About this study

Official title: Diacerein Combined With Febuxostat Relieves Symptoms of Gout by Suppressing IL-1βinflammation

The aim of study was to assess the efficiency and safety of oral IL-1βinhibitor in combination with urate lowering therapy on joint pain intensity,urate control, global assessments of disease activity, self-monitored gouty acute flare times, inflammatory markers and symptoms improving related life quantity in gouty patients.

Read the detailed description

This was a randomized single-dose, open-label and active-controlled study which was carried out in 96 primary gout patients. Subjects and doctors have no access to randomization sequence which is determined by the primary investigator.All patients received an open-label febuxostat 40mg daily during the whole study. Healthy control were 32 age-matched men from volunteers in the medical health center.Two primary end points included pain intensity measurement which was recorded at each visit and subsequently acute flare times which was recorded at home and reported to investigator.

Conditions
Primary Gout
Being tested
Diacerein, Colchicine, Febuxostat

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DiacereinDrug

    Also called Diacetylrhein

    oral administration of IL-1βinhibitory

  • ColchicineDrug

    Also called Colcrys, Generics

    Colchicine is a toxic natural product and secondary metabolite, originally extracted from plants of the genus Colchicum (autumn crocus, Colchicum autumnale, also known as "meadow saffron"). It was used originally to treat rheumatic complaints, especially gout as the positive control

  • FebuxostatDrug

    Also called No other names

    A urate lowering drug, an inhibitor of xanthine oxidase that is indicated for use in the treatment of hyperuricemia and gout

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patients'intensity of pain

    Patients' intensity of pain was assessed at each visit by a single question using a 100mm visual analogue scale (VAS). The pain question was how much pains have you had because of your illness in the past seven days? The two anchors were no pain (0 score) and unbearable pain (score of 100). Patients were instructed to draw a vertical mark on the scaleline and the investigator measured the length and recorded the result.

    Measured: 12 weeks

  2. Acute gout flare times

    Acute gout flare was defined by pain, redness, swelling, and warmth on joints or adjacent soft tissue and pain VAS more than 3.0. For subsequent gout flares, subjects were recorded events by themselves and were reported to investigator whether they had any new or recurrent gout flares since their last visit

    Measured: 24 weeks

Secondary outcomes (5)
  1. Serum and urine urate concentration

    serum urate concentration and 24h urine urate concentration

    Measured: 24 weeks

  2. HAQ

    Healthy Assessment Questionnaire (HAQ) disability index might be valuable to assess the joints function impaired by gout flares.HAQ comprised twenty questions and each question has a corresponding mark : 0, 1 or 2. Sum of each answer of the questions was divided by 20

    Measured: 12 weeks

  3. Flow Cytometry analysis on cell markers

    Inhibitory T cell:CD4 Help T cell:CD8 Natural Killer cell:CD56,CD69,CD16 and CD25 (CD 56 dim and CD56 bright) B cell:CD19 and CD20

    Measured: 12 weeks

  4. Quantitative PCR for mRNA expression of inflammatory cytokines on PBMC

    IL-1β,IL-18, IL-10

    Measured: 12 weeks

  5. Serum concentration of inflammatory cytokines

    IL-1β,IL-10,IL-6 and IL-8 etc.

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Diacerein, Colchicine and Febuxostat in people with Primary Gout, run by Tongji Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. 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 8 May 2014. 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 China. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Patients'intensity of pain (time frame: 12 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 May 2014.
