Efficacy and Safety of Fevipiprant in Asthma: A Review and Meta-Analysis.

Abstract

Fevipiprant is a non-steroidal oral prostaglandin D2 (PGD2) receptor 2 antagonist that reduces bronchial wall inflammation, possibly improving clinical outcomes in the asthmatic population. A systemic review search was conducted on PubMed, Embase, and Central Cochrane Registry. Randomized clinical trials were included with Fevipiprant as an intervention arm compared to placebo. For continuous variables, the standardized mean difference, and for discrete variables, Mantel-Haenszel Risk Ratio (MH Risk ratio) was used for analysis. Confidence interval of 95% and p-value < 0.05 was considered significant. The analysis was done using a random-effects model irrespective of heterogeneity. Heterogeneity was evaluated using the I2 statistic. A total of five articles, including seven trials, were included in the analysis. There was significant increase in post-bronchodilator forced expiratory volume in one second (FEV1) 0.249 (0.157-0.341), p<0.001 and pre-bronchodilator FEV1 0.115 (0.043 to 0.188), p=0.002. A decrease in asthma control questionnaire (ACQ) score of -0.124 (-0.187 to -0.062), p<0.001, was reported. Statistically significant asthma exacerbation reduction was reported in the high eosinophil count population with a daily dose of 450mg 0.77 relative risks (RR) (0.61-0.97). There was a positive deviation toward Fevipiprant 450mg dose for asthma reduction in the overall population, but it was not statistically significant. Fevipiprant produced a slight statistically significant reduction in asthma exacerbations in the high eosinophil count population with favorable deviation in the overall population. It significantly increased pre-and post-bronchodilator FEV1 and improved ACQ scores in treated patients. The benefits, though statistically significant, failed to translate into clinical importance.
