Baricitinib plus Remdesivir for Hospitalized Adults with Covid-19.

ABSTRACT:

Background

Severe coronavirus disease 2019 (Covid-19) is associated with dysregulated inflammation. The effects of combination treatment with baricitinib, a Janus kinase inhibitor, plus remdesivir are not known.

Methods

We conducted a double-blind, randomized, placebo-controlled trial evaluating baricitinib plus remdesivir in hospitalized adults with Covid-19. All the patients received remdesivir (≤10 days) and either baricitinib (≤14 days) or placebo (control). The primary outcome was the time to recovery. The key secondary outcome was clinical status at day 15.

Results

A total of 1033 patients underwent randomization (with 515 assigned to combination treatment and 518 to control). Patients receiving baricitinib had a median time to recovery of 7 days (95% confidence interval [CI], 6 to 8), as compared with 8 days (95% CI, 7 to 9) with control (rate ratio for recovery, 1.16; 95% CI, 1.01 to 1.32; P = 0.03), and a 30% higher odds of improvement in clinical status at day 15 (odds ratio, 1.3; 95% CI, 1.0 to 1.6). Patients receiving high-flow oxygen or noninvasive ventilation at enrollment had a time to recovery of 10 days with combination treatment and 18 days with control (rate ratio for recovery, 1.51; 95% CI, 1.10 to 2.08). The 28-day mortality was 5.1% in the combination group and 7.8% in the control group (hazard ratio for death, 0.65; 95% CI, 0.39 to 1.09). Serious adverse events were less frequent in the combination group than in the control group (16.0% vs. 21.0%; difference, -5.0 percentage points; 95% CI, -9.8 to -0.3; P = 0.03), as were new infections (5.9% vs. 11.2%; difference, -5.3 percentage points; 95% CI, -8.7 to -1.9; P = 0.003).

Conclusions

Baricitinib plus remdesivir was superior to remdesivir alone in reducing recovery time and accelerating improvement in clinical status among patients with Covid-19, notably among those receiving high-flow oxygen or noninvasive ventilation. The combination was associated with fewer serious adverse events. (Funded by the National Institute of Allergy and Infectious Diseases; ClinicalTrials.gov number, NCT04401579.).

Project description:IntroductionBaricitinib-remdesivir (BARI-REM) combination is superior to remdesivir (REM) in reducing recovery time and accelerating clinical improvement among hospitalized patients with coronavirus disease 2019 (COVID-19), specifically those receiving high-flow oxygen/noninvasive ventilation. Here we assessed the cost-effectiveness of BARI-REM versus REM in hospitalized patients with COVID-19 in the USA.MethodsA three-state model was developed addressing costs and patient utility associated with COVID-19 hospitalization, immediate post hospital care, and subsequent lifetime medical care. Analysis was performed from the perspective of a payer and a hospital. Both perspectives evaluated two subgroups: all patients and patients who required oxygen. The primary measures of benefit in the model were patient quality-adjusted life years (QALYs) accrued during and after hospitalization, cost per life years gained, cost per death avoided, and cost per use of mechanical ventilation avoided.ResultsIn the base-case payer perspective with a lifetime horizon, treatment with BARI-REM versus REM resulted in an incremental total cost of $7962, a gain of 0.446 life years and gain of 0.3565 QALYs over REM. The incremental cost-effectiveness ratios of using BARI-REM were estimated as $22,334 per QALY and $17,858 per life year. The base-case and sensitivity analyses showed that the total incremental cost per QALY falls within the reduced willingness-to-pay threshold of $50,000/QALY applied under health emergencies. In all hospitalized patients, treatment with BARI-REM versus REM reduced total hospital expenditures per patient by $1778 and total reimbursement payments by $1526, resulting in a $252 reduction in net costs per patient; it also resulted in a net gain of 0.0018 QALYs and increased survival of COVID-19 hospitalizations by 2.7%.ConclusionOur study showed that BARI-REM is cost-effective compared to using REM for hospitalized patients with COVID-19. The base-case results of this cost-effectiveness model were most sensitive to average annual medical costs for recovered patients.

Project description:ImportanceSARS-CoV-2, which causes COVID-19, poses considerable morbidity and mortality risks. Studies using data collected during routine clinical practice can supplement randomized clinical trials to provide needed evidence, especially during a global pandemic, and can yield markedly larger sample sizes to assess outcomes for important patient subgroups.ObjectiveTo evaluate the association of remdesivir treatment with inpatient mortality among patients with COVID-19 outside of the clinical trial setting.Design, setting, and participantsA retrospective cohort study in US hospitals using health insurance claims data linked to hospital chargemaster data from December 1, 2018, to May 3, 2021, was conducted among 24 856 adults hospitalized between May 1, 2020, and May 3, 2021, with newly diagnosed COVID-19 who received remdesivir and 24 856 propensity score-matched control patients.ExposureRemdesivir treatment.Main outcomes and measuresAll-cause inpatient mortality within 28 days of the start of remdesivir treatment for the remdesivir-exposed group or the matched index date for the control group.ResultsA total of 24 856 remdesivir-exposed patients (12 596 men [50.7%]; mean [SD] age, 66.8 [15.4] years) and 24 856 propensity score-matched control patients (12 621 men [50.8%]; mean [SD] age, 66.8 [15.4] years) were included in the study. Median follow-up was 6 days (IQR, 4-11 days) in the remdesivir group and 5 days (IQR, 2-10 days) in the control group. There were 3557 mortality events (14.3%) in the remdesivir group and 3775 mortality events (15.2%) in the control group. The 28-day mortality rate was 0.5 per person-month in the remdesivir group and 0.6 per person-month in the control group. Remdesivir treatment was associated with a statistically significant 17% reduction in inpatient mortality among patients hospitalized with COVID-19 compared with propensity score-matched control patients (hazard ratio, 0.83 [95% CI, 0.79-0.87]).Conclusions and relevanceIn this retrospective cohort study using health insurance claims and hospital chargemaster data, remdesivir treatment was associated with a significantly reduced inpatient mortality overall among patients hospitalized with COVID-19. Results of this analysis using data collected during routine clinical practice and state-of-the-art methods complement results from randomized clinical trials. Future areas of research include assessing the association of remdesivir treatment with inpatient mortality during the circulation of different variants and relative to time from symptom onset.
