ABSTRACT
KEY POINTS: In a multicenter point-prevalence study, we found that the rate of supportive care was high; among those receiving COVID-19 drug therapies, adverse reactions occurred in 12% of patients. PURPOSE: There are currently no FDA-approved medications for the treatment of coronavirus disease 2019 (COVID-19). At the onset of the pandemic, off-label medication use was supported by limited or no clinical data. We sought to characterize experimental COVID-19 therapies and identify safety signals during this period. METHODS: We conducted a noninterventional, multicenter, point prevalence study of patients hospitalized with suspected/confirmed COVID-19. Clinical and treatment characteristics within a 24-hour window were evaluated in a random sample of up to 30 patients per site. The primary objective was to describe COVID-19-targeted therapies. The secondary objective was to describe adverse drug reactions (ADRs). RESULTS: A total of 352 patients treated for COVID-19 at 15 US hospitals From April 18 to May 8, 2020, were included in the study. Most patients were treated at academic medical centers (53.4%) or community hospitals (42.6%). Sixty-seven patients (19%) were receiving drug therapy in addition to supportive care. Drug therapies used included hydroxychloroquine (69%), remdesivir (10%), and interleukin-6 antagonists (9%). Five patients (7.5%) were receiving combination therapy. The rate of use of COVID-19-directed drug therapy was higher in patients with vs patients without a history of asthma (14.9% vs 7%, P = 0.037) and in patients enrolled in clinical trials (26.9% vs 3.2%, P < 0.001). Among those receiving drug therapy, 8 patients (12%) experienced an ADR, and ADRs were recognized at a higher rate in patients enrolled in clinical trials (62.5% vs 22%; odds ratio, 5.9; P = 0.028). CONCLUSION: While we observed high rates of supportive care for patients with COVID-19, we also found that ADRs were common among patients receiving drug therapy, including those enrolled in clinical trials. Comprehensive systems are needed to identify and mitigate ADRs associated with experimental COVID-19 treatments.

Drug therapies included hydroxychloroquine (69%), remdesivir (10%), and interleukin-6 inhibitors (9%). Five patients (7.5%) were receiving combination therapy. Patients with a history of asthma (14.9% vs. 7%, p=0.037) and those enrolled in clinical trials (26.9% vs. 3.2%, p<0.001) were more likely to receive therapy. Among those receiving COVID-19 therapy, eight patients (12%) experienced an ADR, and ADRs were more commonly recognized in patients enrolled in clinical trials (62.5% vs 22%, OR=5.9, p=0.028). CONCLUSIONS: While we observed high rates of supportive care for patients with COVID-19, we also found that ADRs were common among patients receiving drug therapy including in clinical trials. Comprehensive systems are needed to identify and mitigate ADRs associated with experimental COVID-19 therapies.
