Ruxolitinib versus Dexamethasone in Hospitalized Adults with Covid-19: multicenter matched-controlled study
2021
Abstract Background Several anti-cytokine therapies were tested in the randomized trials in hospitalized patients with severe acute respiratory syndrome coronavirus 2 infection (COVID-19). Both janus kinase (JAK) inhibitor, baricitinib, and dexamethasone demonstrated the reduction of mortality. In this matched control study we compared dexamethasone to another JAK inhibitor, ruxolitinib. Methods The study included 146 hospitalized patients with COVID-19 and oxygen support requirement. The control group was selected 1:1 from 1355 dexamethasone-treated patients and was matched by 29 clinical and laboratory parameters predicting survival. Results Ruxolitinib treatment in the general cohort of patients was associated with equivalent to dexamethasone mortality rate: 9,6% (95% CI 4,6-14,6%) vs 13,0% (95% CI 7,5-18,5%, superiority p=0.35, non-inferiority p=0.0137), respectively. Time to discharge without oxygen support requirement was also not different between these groups: 13 vs 11 days (p=0.13). Subgroup analysis without adjustment for multiple comparisons demonstrated reduced mortality in ruxolitnib-treated patients with febrile fever (OR 0.33, 95%CI 0.11-1.00). Except higher incidence of grade 1 thrombocytopenia (37% vs 23%, p=0.042), ruxolitinib therapy was associated with better safety profile due to reduced rate of severe cardiovascular adverse events (6.8% vs 15%, p=0.025). Conclusions Ruxolitinib may be an alternative anti-cytokine therapy with comparable efficacy in patients with potential risks of steroid administration. Patients with febrile fever at admission may benefit from ruxolitinib administration. Funding Ruxolitinib was obtained from Novartis through Managed Access Program (MAP).
