Long-term lumiracoxib treatment non-inferior to celecoxib in patients with osteoarthritis .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(2):90 BMC Musculoskelet Disord. 2008 Mar 7;9:32.320 patients (>40 yr of age) with osteoarthritis of the hip, knee, hand, or spine were randomized to receive 100 mg of lumiracoxib, once or twice daily, or celecoxib 200 mg, once daily, for 52 week period. The purpose of the study was to compare the long-term efficacy, safety and tolerability in this population. Lumiracoxib 100 mg, once daily dose, was found to be safe and effective and had similar long-term retention effects as celecoxib 200 mg in patients with osteoarthritis (OA); Lumiracoxib 100 mg, once daily dose was non-inferior to celecoxib 200 mg.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?
Sì = 1

L'Indice di Fragilità è uno strumento che aiuta l'interpretazione dei risultati significativi, fornendo una misura della forza di un risultato. L'Indice di Fragilità rappresenta il numero di eventi consecutivi che devono essere aggiunti a un risultato dicotomico per rendere il risultato non più significativo. Un numero piccolo rappresenta un risultato più debole, mentre un numero grande rappresenta un risultato più forte.
Perché questo studio era necessario ora?
Osteoarthritis is a well-documented condition that is especially prevalent in older populations, associated with decreases in mobility and consequently, quality of life. Patients may pursue a wide variety of pharmacological treatments including analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), and selective cyclooxygenase inhibitors. However, the complications with extended use be serious. Lumiracoxib, elective cyclooxygenase inhibitor, has been cited to be efficacious, safe and tolerable, but the long-term have yet to be examined. This study compared the effects of lumiracoxib with those of celecoxib in patients with osteoarthritis.
Qual era la domanda di ricerca principale?
Is lumiracoxib superior to celecoxib in terms of OA pain in the target joint, patient's and physician's global assessments of disease activity, Short Arthritis Assessment Scale (SAS) total score, rescue medication use, safety, and tolerability, when assessed up to 1 year?
- Retention rates at 1 year for the lumiracoxib 100 mg o.d group were 46.9%, for the lumiracoxib 100 mg b.i.d group 47.5%, and for the celecoxib 200 mg o.d. group 45.3%. The retention on treatment with lumiracoxib (at either dose) was revealed to be non-inferior to celecoxib 200 mg o.d, with estimated differences of 0.02 (97.5% CI -0.04 to 0.07) for lumiracoxib 100 mg o.d and 0.02 (97.5% CI -0.03 to 0.07) for lumiracoxib 100 mg b.i.d.
- No between group differences were observed for improvement in OA pain intensity, the patient's global assessment of disease activity, and the physician's global assessment of disease activity.
- Overall incidence of adverse events was similar among the three groups; 72.6% in lumiracoxib 100 mg o.d.group, 71.0% in lumiracoxib 100 mg b.i.d. group and 69.4% in celecoxib 200 mg b.i.d group. Moreover, incidence of serious adverse events was comparable in groups; 5.4%, 4.7%, and 6.3%, respectively.
- Incidence of prespecified AEs, adjudicated GI, CV/cerebrovascular, liver events, AST/ALT >3 × ULN, and definite/probable APTC events were similar between groups.
Che cosa devo ricordare di più?
Long-term efficacy and tolerability with lumiracoxib 100 mg o.d. was non-inferior to celecoxib 200 mg o.d. in patients with osteoarthritis when assessed up to 1 year.
Come influenzerà l'assistenza ai miei pazienti?
Although the results of this study indicated that all treatments were well tolerated and yielded similar results in most of the outcome measures (both primary and secondary outcome measures), lumiracoxib has actually been withdrawn from various markets starting 2007 due to its adverse effect profile. As such, these findings should be interpreted with great caution.
