Pharmacotherapy describes the successful treatment of a patient with COVID-19 with remdesivir antiviral therapy 13 days after symptom onset. A male aged 40 years was admitted to Mercy Health Saint Mary’s Hospital, Grand Rapids, Michigan, 3 days after the onset of COVID-19 symptoms (cough, fever, shortness of breath). The patient was obese, had hypercholesterolemia, and had a history of anxiety, depression, and vaping with nicotine. The patient’s condition progressed and he was mechanically ventilated. A request for compassionate use remdesivir was submitted on the same day he tested positive for SARS-CoV-2 on positive real-time reverse transcriptase polymerase chain reaction (RT-PCR).Supportive measures, including a 5‐day course of hydroxychloroquine, cefepime 2 g every 8 hours, and azithromycin 500 mg every 24 hours were maintained until remdesivir was delivered on day 9 of hospitalisation (13 days after symptom onset). A 200 mg IV loading dose was administered to the patient, followed by 100 mg IV maintenance dose every 24 hours for the next 9 days. During the following 48 hours, the patient continued to progress and was able to tolerate aggressive mechanical ventilation weaning. On day 16 of illness (hospital day 12), he was extubated without incident. Oxygen saturations remained stable requiring 2 to 3 litres of oxygen by nasal cannula and his oxygenation saturation was maintained on room air by day 17 of illness (hospital day 13).The patient continues to be in stable condition on room air and is progressing towards discharge. “Late initiation of remdesivir may be effective in treating SARS‐CoV‐2, unlike antivirals utilised for different disease states, such as oseltamivir, which are most effective when started as soon as possible following symptom onset,” wrote Julie J. Belfer, Mercy Health Saint Mary’s, and colleagues. “Urgent action is needed by regulatory agencies to work with drug manufacturers to expedite the study and approval of investigational agents targeting SARS‐CoV‐2 as well as to meet manufacturing demands.”
