Efficacy of Immunobiologic and Small Molecule Inhibitor Drugs for Psoriasis: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

ABSTRACT:

Background

Psoriasis is an immune-mediated inflammatory disease for which treatment has evolved over the past few years due to the introduction of immunobiologic and small molecule inhibitor medications. A better understanding of the comparative efficacies of drugs may help doctors to choose the most appropriate treatment for patients.

Objective

The aim of this study was to conduct a systematic review and meta-analysis to assess the efficacy of immunobiologic and small molecule inhibitor drugs for patients with moderate to severe psoriasis.

Data sources

The EMBASE, PUBMED, LILACS, Web of Science and ClinicalTrials.org databases were searched for trials published to 21 July 2016.

Study selection

Only randomized, double-blind, placebo-controlled clinical trials that evaluated the efficacy of immunobiologics or small molecule inhibitors for moderate to severe plaque-type psoriasis were selected by two independent authors. No restrictions were used.

Data extraction and synthesis

Two authors independently extracted the data and a random-effects model meta-analysis was performed.

Main outcomes and measures

The Psoriasis Area and Severity Index (PASI) 75 was considered the primary outcome, measured at the primary endpoint of each study.

Results

Thirty-eight studies were included in our analysis. The overall pooled effect favored biologics and small molecule inhibitors over placebo (risk difference [RD] 0.59, 95% confidence interval [CI] 0.58-0.60). Ixekizumab at a dose of 160 mg on week 0 and then every 2 weeks (RD 0.84, 95% CI 0.81-0.88), brodalumab 210 mg (RD 0.79, 95% CI 0.76-0.82), infliximab 5 mg/kg (RD 0.76, 95% CI 0.73-0.79), and secukinumab 300 mg (RD 0.76, 95% CI 0.71-0.81) showed a greater chance of response (PASI 75) when compared with placebo.

Limitations

The methodology of a traditional meta-analysis does not allow for drugs to be ranked. Included studies used short-term endpoints (10-16 weeks) to evaluate the primary outcome, therefore long-term efficacy could not be determined.

Conclusions and relevance

The anti-IL-17 drugs brodalumab, ixekizumab and secukinumab showed an equal or greater chance of helping patients achieve a 75% improvement on PASI compared with other reviewed drugs.

Project description:BackgroundOrally effective therapeutics for plaque psoriasis with improved response rates, lower toxicity and costs are needed in clinical practices. This study aims to assess the efficacy and safety of the recently approved TYK2 inhibitor deucravacitinib in adults with moderate to severe plaque psoriasis through meta-analysis.MethodsA systematic search was performed for eligible studies using electronic databases, including PubMed, Embase, Cochrane Library, Clinical Trials, the EU Clinical Trials Register, and the International Clinical Trials Registry Platform (ICTRP). Randomized controlled trials (RCTs) comparing the efficacy and safety of deucravacitinib vs. placebo or active comparators in adult patients with plaque psoriasis were included. The effectiveness of deucravacitinib was evaluated using a 75% improvement in Psoriasis Area and Severity Index (PASI 75) from baseline and the proportion of patients achieving the static Physician's Global Assessment (sPGA) response. The secondary endpoint was the proportion of patients achieving PASI 90, PASI 100, ssPGA 0/1, and Dermatology Life Quality Index 0/1 (DLQI). The incidence of adverse events (AEs), serious AEs (SAEs), and AE-related treatment discontinuation were statistically analyzed to determine the safety of deucravacitinib.ResultsThe systematic review and meta-analysis included five RCTs involving 2,198 patients with moderate to severe plaque psoriasis. Results showed that deucravacitinib was superior to placebo as well as active comparator apremilast in multiple key endpoints, including PASI 75, sPGA 0/1, PASI 90, PASI 100, DLQI 0/1 at week 16. Moreover, a durable response was seen in the two 52-week studies. Safety assessment showed that deucravacitinib was generally well tolerated, and the incidence of AEs, SAEs, and AE-related treatment discontinuation was low and balanced across groups.ConclusionDeucravacitinib demonstrated superior efficacy to apremilast in adult patients with moderate to severe plaque psoriasis with an acceptable safety profile and has the potential to be used as the first-line oral therapy for plaque psoriasis.

Project description:The relative efficacy of antihypertensive drugs/combinations is not well known. Identifying the most effective ones and the patients' characteristics associated with best performance of the drugs will improve management of hypertensive patients.To assess the blood pressure (BP) reduction attributed to antihypertensive drugs and identify characteristics associated with BP decrease.MEDLINE, Cochrane Central Register of Controlled Trials from inception through July 2012 and selected papers.Double-blind, randomized clinical trials whose main result was the reduction in BP by antihypertensive treatment, with study population ?50 or ?25 if the study was a crossover, follow-up of at least 8 weeks, and available required data.Study data were independently extracted by multiple observers and introduced in an electronic database. Inconsistencies were resolved by discussion and referral back to the original articles. Meta-analysis was performed according to PRISMA statement and using a Bayesian framework.Mean decrease in systolic (SBP) and diastolic blood pressure (DBP) achieved by each drug or combination.Two hundred eight trials including 94,305 patients were identified. In monotherapy, most drugs achieved 10 to 15?mm Hg SBP and 8 to 10?mm Hg DBP decreases.Olmesartan/amlodipine, olmesartan/hydrochlorothiazide, felodipine/metoprolol, and valsartan/hydrochlorothiazide were the combinations leading to the greatest mean SBP reductions (>20?mm Hg). Female sex and body mass index >25?kg/m were associated with more pronounced SBP and DBP reductions, whereas Afro-American ethnicity was associated with BP reductions smaller than the median. Results were adjusted by study duration, cardiovascular disease, and diabetes mellitus. Still, the estimation was performed using the mean administered doses, which do not exactly match those of the available drug formats.Data corresponded to those obtained in each of the included trials; the analysis of the combinations was limited to the most recent ones; estimations were performed using the mean administered doses.Certain drug combinations achieve BP reductions ranging from 20 to 25/10 to 15?mm Hg. Sex, ethnicity, and obesity are associated with antihypertensive response. This information can contribute to better selection of the antihypertensive drug, depending on the magnitude of pretreatment BP elevation. Guidelines should be revised.

Project description:We systematically compared the effects of prophylactic anticonvulsant drug use in patients with traumatic brain injury. We searched four electronic databases from their inception until July 13, 2021. Two researchers independently screened, appraised, and extracted the included studies. Network meta-analysis using multivariate random effects and a frequentist framework was adopted for data analysis. The risk of bias of each study was assessed using the Cochrane risk of bias tool, and confidence in evidence was assessed through confidence in network meta-analysis (CINeMA). A total of 11 randomized controlled trials involving 2,450 participants and six different treatments (i.e., placebo, carbamazepine, phenytoin, levetiracetam, valproate, and magnesium sulfate) were included. We found that anticonvulsant drugs as a whole significantly reduced early posttraumatic seizures (PTS) but not late PTS compared with placebo (odd ratios [ORs] = 0.42 and 0.82, 95% confidence intervals [CIs] = 0.21-0.82 and 0.47-1.43). For the findings of network meta-analysis, we observed that phenytoin (ORs = 0.43 and 0.71; 95% CIs = 0.18-1.01 and 0.23-2.20), levetiracetam (ORs = 0.56 and 1.58; 95% CIs = 0.12-2.55 and 0.03-84.42), and carbamazepine (ORs = 0.29 and 0.64; 95% CIs = 0.07-1.18 and 0.08-5.28) were more likely to reduce early and late PTS compared with placebo; however, the treatment effects were not significant. Sensitivity analysis, after excluding a study enrolling only children, revealed that phenytoin had a significant effect in preventing early PTS (OR = 0.33; 95% CI = 0.14-0.78). Our findings indicate that no antiepileptic drug had an effect on early or late PTS superior to that of another; however, the sensitivity analysis revealed that phenytoin might prevent early PTS. Additional studies with large sample sizes and a rigorous design are required to obtain high-quality evidence on prophylactic anticonvulsant drug use in patients with traumatic brain injury.
