Project description:ImportanceMost clinical trials assessing systemic immunomodulatory treatments for patients with atopic dermatitis are placebo-controlled.ObjectiveTo compare the effectiveness and safety of systemic immunomodulatory treatments for patients with atopic dermatitis in a systematic review and network meta-analysis.Data sourcesThe Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Latin American and Caribbean Health Science Information database, Global Resource of Eczema Trials database, and clinical trial registries were searched from inception to October 28, 2019.Study selectionEnglish-language randomized clinical trials of 8 weeks or more of treatment with systemic immunomodulatory medications for moderate to severe atopic dermatitis were included. Titles, abstracts, and articles were screened in duplicate. Of 10 324 citations, 39 trials were included.Data extraction and synthesisData were extracted in duplicate, and the review adhered to Preferred Reporting Items for Systematic Reviews and Meta-analyses for Network Meta-Analyses guidelines. Random-effects bayesian network meta-analyses were performed and certainty of evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation criteria.Main outcomes and measuresPrespecified outcomes were change in signs of disease, symptoms, quality of life, itch, withdrawals, and serious adverse events.ResultsA total of 39 trials with 6360 patients examining 20 medications and placebo were included. Most trials were conducted for adults receiving up to 16 weeks of therapy. Dupilumab, 300 mg every 2 weeks, was associated with improvement in the Eczema Area and Severity Index score vs placebo (mean difference, 11.3-point reduction; 95% credible interval [CrI], 9.7-13.1 [high certainty]). Cyclosporine (standardized mean difference, -1.1; 95% CrI, -1.7 to -0.5 [low certainty]) and dupilumab (standardized mean difference, -0.9; 95% CrI, -1.0 to -0.8 [high certainty]) were similarly effective vs placebo in clearing clinical signs of atopic dermatitis and may be superior to methotrexate (standardized mean difference, -0.6; 95% CrI, -1.1 to 0.0 [low certainty]) and azathioprine (standardized mean difference, -0.4; 95% CrI, -0.8 to -0.1 [low certainty]). Several investigational medications for atopic dermatitis are promising, but data to date are limited to small early-phase trials. Safety analyses were limited by low event rates.Conclusions and relevanceDupilumab and cyclosporine may be more effective for up to 16 weeks of treatment than methotrexate and azathioprine for treating adult patients with atopic dermatitis. More studies directly comparing established and novel treatments beyond 16 weeks are needed and will be incorporated into future updates of this review.

Project description:BackgroundCurrently, 6-month oxaliplatin-based chemotherapy has been recommended as the preferred adjuvant treatment against high-risk stage 2 and stage 3 colon cancer patients.MethodsRecord retrieval was conducted in PubMed, Web of Science, Cochrane Central Register of Controlled Trials, American Society of Clinical Oncology and European Society for Medical Oncology meeting libraries from inception to November 2019. Regarding survival and tolerability, randomized controlled trials comparing different adjuvant systemic regimens against high-risk stage 2 and stage 3 colon cancer were eligible. Disease-free survival was primary endpoint. Network calculation was based on a random-effects model, and relative ranking of each node was numerically indicated by p score.ResultsA total of 30 trials were included, corresponding to 54,109 patients. Regarding disease-free survival, none of the analyzed regimens displayed significant superiority against common comparator 6-month capecitabine plus oxaliplatin (XELOX), while 12-month [network hazard ratio (HR) 0.81 (0.60-1.10); 0.79 (0.57-1.10)] and 3-month XELOX [0.95 (0.86-1.04); 0.93 (0.83-1.05)] were top-ranking regimens showing non-inferiority among overall and stage 3 patients. Moreover, by pairwise meta-analysis, 3-month XELOX demonstrated significant superiority against 6-month XELOX among low-risk stage 3 patients [pairwise HR 0.78 (0.63-0.97)]. Concerning adverse events, 3-month oxaliplatin-based chemotherapy was significantly better than the 6-month counterpart with respect to peripheral sensory neuropathy, thrombocytopenia and fatigue. The 12-month capecitabine monotherapy failed to display non-inferiority among other major adverse events.ConclusionsThe 3-month XELOX treatment could be an alternative option of the 6-month regimen among low-risk stage 3 patients. Among high-risk stage 3 patients, 6-month oxaliplatin-based regimens still seem more competitive. In addition, clinical application of 12-month capecitabine monotherapy should be cautious, despite its top rankings, especially among non-Asian countries.

Project description:ImportanceSystemic treatments for atopic dermatitis are being evaluated primarily in placebo-controlled trials; network meta-analysis can provide relative efficacy and safety estimates for treatments that have not been compared head to head.ObjectiveTo compare reported measures of efficacy and assessments of safety in clinical trials of systemic treatments for atopic dermatitis in a living systematic review and network meta-analysis.Data sourcesThe Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Latin American and Caribbean Health Science Information database, Global Resource of EczemA Trials database, and trial registries were searched through June 15, 2021.Study selectionRandomized clinical trials examining 8 or more weeks of treatment with systemic immunomodulatory medications for moderate-to-severe atopic dermatitis were included after screening titles, abstracts, and papers in duplicate.Data extraction and synthesisData were abstracted in duplicate. Bayesian network meta-analyses and assessed Grading of Recommendations Assessment, Development and Evaluation certainty of evidence were performed. The updated analysis was completed from June to December 2021.Main outcomes and measuresOutcomes include change in Eczema Area and Severity Index (EASI), Patient Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), and Peak Pruritus Numeric Rating Scales (PP-NRS).ResultsSince October 2019, 21 new studies were added, for a total of 60 trials with 16 579 patients. Up to 16 weeks of treatment in adults, abrocitinib, 200 mg daily (mean difference [MD], 2.2; 95% credible interval [CrI], 0.2-4.0; high certainty) and upadacitinib, 30 mg daily (MD, 2.7; 95% CrI, 0.6-4.7; high certainty) were associated with reduced EASI slightly more than dupilumab, 600 mg then 300 mg every 2 weeks. Abrocitinib, 100 mg daily (MD, -2.1; 95% CrI, -4.1 to -0.3; high certainty), baricitinib, 4 mg daily (MD, -3.2; 95% CrI, -5.7 to -0.8; high certainty), baricitinib, 2 mg daily (MD, -5.2; 95% CrI, -7.5 to -2.9; high certainty) and tralokinumab, 600 mg then 300 mg every 2 weeks (MD, -3.5; 95% CrI, -5.8 to -1.3; high certainty) were associated with reduced EASI slightly less than dupilumab. There was little or no difference between upadacitinib, 15 mg daily, and dupilumab (MD, 0.2; 95% CrI, -1.9 to 2.2; high certainty). The pattern of results was similar for POEM, DLQI, and PP-NRS.Conclusions and relevanceIn this systematic review and meta-analysis, abrocitinib, 200 mg; and upadacitinib, 30 mg daily, were associated with slightly better scores than dupilumab, and upadacitinib, 15 mg daily, was associated with similar scores to dupilumab. Abrocitinib, 100 mg daily, baricitinib, 4 mg and 2 mg daily, and tralokinumab, 300 mg, every 2 weeks were associated with slightly worse scores.

Project description:ImportanceMultiple systemic treatments are available for metastatic castration-sensitive prostate cancer (mCSPC), with unclear comparative effectiveness and safety and widely varied costs.ObjectiveTo compare the effectiveness and safety determined in randomized clinical trials of systemic treatments for mCSPC.Data sourcesBibliographic databases (MEDLINE, Embase, and Cochrane Central), regulatory documents (US Food and Drug Administration and European Medicines Agency), and trial registries (ClinicalTrials.gov and European Union clinical trials register) were searched from inception through November 5, 2019.Study selection, data extraction, and synthesisEligible studies were randomized clinical trials evaluating the addition of docetaxel, abiraterone acetate, apalutamide, or enzalutamide to androgen-deprivation therapy (ADT) for treatment of mCSPC. Two investigators independently performed screening. Discrepancies were resolved through consensus. A Cochrane risk-of-bias tool was used to assess trial quality. Relative effects of competing treatments were assessed by bayesian network meta-analysis and survival models. The Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline was used.Main outcomes and measuresOverall survival, radiographic progression-free survival, and serious adverse events (SAEs).ResultsSeven trials with 7287 patients comparing 6 treatments (abiraterone acetate, apalutamide, docetaxel, enzalutamide, standard nonsteroidal antiandrogen, and placebo/no treatment) were identified. Ordered from the most to the least effective determined by results of clinical trials, treatments associated with improved overall survival when added to ADT included abiraterone acetate (hazard ratio [HR], 0.61; 95% credible interval [CI], 0.54-0.70), apalutamide (HR, 0.67; 95% CI, 0.51-0.89), and docetaxel (HR, 0.79; 95% CI, 0.71-0.89); treatments associated with improved radiographic progression-free survival when added to ADT included enzalutamide (HR, 0.39; 95% CI, 0.30-0.50), apalutamide (HR, 0.48; 95% CI, 0.39-0.60), abiraterone acetate (HR, 0.51; 95% CI, 0.45-0.58), and docetaxel (HR, 0.67; 95% CI 0.60-0.74). Docetaxel was associated with substantially increased SAEs (odds ratio, 23.72; 95% CI, 13.37-45.15), abiraterone acetate with slightly increased SAEs (odds ratio, 1.42; 95% CI, 1.10-1.83), and other treatments with no significant increase in SAEs. Risk of bias was noted for 4 trials with open-label design, 3 trials with missing data, and 2 trials with potential unprespecified analyses.Conclusions and relevanceIn this network meta-analysis, as add-on treatments to ADT, abiraterone acetate and apalutamide may provide the largest overall survival benefits with relatively low SAE risks. Although enzalutamide may improve radiographic progression-free survival to the greatest extent, longer follow-up is needed to examine the overall survival benefits associated with enzalutamide.
