Effectiveness, Tolerability, and Safety of Belimumab in Patients with Refractory SLE: a Review of Observational Clinical-Practice-Based Studies.

ABSTRACT: To date, belimumab is the only biological drug approved for the treatment of patients with active refractory SLE. We compared and critically analyzed the results of 11 observational clinical-practice-based studies, conducted in SLE referral centers. Despite the differences in endpoints and follow-up duration, all studies remarked that belimumab provides additional benefits when used as an add-on to existing treatment, allowing a higher rate of patients to reach remission and to taper or discontinue corticosteroids. In the OBSErve studies, 2-9.6% of patients discontinued corticosteroids and 72-88.4% achieved a ??20% improvement by physician's judgment at 6 months. In Hui-Yuen's study, 51% of patients attained response by simplified SRI at month 6. In Sthoeger's study, 72.3% of patients discontinued corticosteroids and 69.4% achieved clinical remission by PGA after a median follow-up of 2.3 years. In the multicentric Italian study, 77 and 68.7% of patients reached SRI-4 response at months 6 and 12, respectively. In all the studies, disease activity indices decreased over time. Retention rates at 6, 9, and 12 months were 82-94.1, 61.2-83.3, and 56.7-79.2%, respectively. The main limitations of these studies include the lack of a control group, the short period of observation (6-24 months) and the lack of precise restrictions regarding concomitant medication management. This notwithstanding, these experiences provide a more realistic picture of real-life effectiveness of the drug compared with the randomized controlled clinical trials, where stringent inclusion/exclusion criteria and changes in background therapy could limit the inference of data to the routine clinical care.

Project description:Background: Although infliximab has been recommended for the second-line treatment of seronegative spondyloarthropathy- or juvenile idiopathic arthritis-related uveitis, the issue of its systemic efficacy and safety in a broader diversity of refractory noninfectious uveitis is debatable. To assess the short-term and relatively long-term efficacy of infliximab in refractory noninfectious uveitis, we performed a systematic review and meta-analysis of observational studies. Methods: PubMed, Cochrane Library, EMBASE, and Wanfang Med Online were systematically searched from January 2005 to March 2020. Two investigators independently assessed eligibility. Data were independently collected by two investigators. The pooled proportions were estimated with patients for intraocular inflammation control and improvement of visual acuity. Pooled proportions with 95% credible intervals were computed. Study homogeneity was investigated using I 2 statistics to quantify the percentage of variation across studies. To pool the results, the Mantel-Haenszel fixed-effects or random-effects models were used. Results: Of 2316 studies identified, 16 unique studies with 509 unique participants were included in the meta-analysis. The pooled proportions of intraocular inflammation control reached 92% (95% CI: 87%-98%; I 2: 1%; p=0.42) and 95% (95% CI: 93%-97%; I 2: 0%; p=0.91) in groups of ≤6- and ≥12-month follow-up durations. During the relatively long follow-up period, the pooled proportions of maintaining visual acuity stable or increasing at least one line reached 99% (95% CI: 96%-100%; I 2: 0%; p=0.54) in the involved eyes. The corticosteroid-sparing effect of infliximab was also well demonstrated, with the proportion of corticosteroid-sparing success reaching 85.5% (112/131). Besides, about serious adverse events, 2.6% (13/500) of patients experienced hypersensitivity reactions, 2.4% (12/500) of patients experienced serious infections, 1.8% (9/500) of patients experienced autoimmune diseases, and 0.6% (3/500) of patients experienced neoplasia. Conclusions: This meta-analysis provided evidence that infliximab might be a promising choice in controlling inflammatory activity, gaining visual acuity, and sparing corticosteroid use with relatively few side effects when applied in treating refractory noninfectious uveitis.
