The outcomes of the ACTT-1 trial, which seemed on the effectiveness of remdesivir as a therapy for COVID-19, have lastly been printed. Thus far the one drug that has been proven to cut back deaths from the illness has been dexamethasone, a steroid that suppresses the immune system via its anti-inflammatory results. Steroids have a secondary impact on the illness – they don’t goal the virus itself. Remdesivir, alternatively, goes straight to the reason for the illness by inhibiting the virus.
The drug, which was developed by Gilead Sciences, was authorized to be used by the US Meals and Drug Administration underneath an “emergency use authorisation” on Might 1. It was just lately used to deal with President Donald Trump.
Gilead Sciences has claimed that the drug has important advantages for sufferers – however sturdy knowledge has been missing till now. This makes the long-awaited outcomes of the ACTT-1 trial vital. Having learn the examine, most physicians treating sufferers with COVID-19 can be asking themselves the identical query: “Ought to I be utilizing remdesivir for my sufferers?”
Ought to all COVID-19 sufferers get remdesivir?
The trial follows a gold-standard design of being double blind, randomised and managed, and like most trials printed in high medical journals, at first look the outcomes are pretty spectacular. They discovered that sufferers receiving the drug improved and recovered extra shortly, have been much less more likely to progress to extreme illness, have been discharged from hospital sooner, and had a decrease dying fee of 11.4% in contrast with 15.2% in sufferers receiving “ordinary” therapy.
Based mostly on these constructive findings, it might be tempting to conclude that each one sufferers who’ve the illness ought to obtain the drug, however because it prices round US$2,340 (£1,795) to deal with one affected person, and is more likely to be briefly provide within the UK for the foreseeable future, the query warrants a extra thought-about evaluation.
The usage of any drug additionally has probably detrimental penalties. Remdesivir has not been round lengthy sufficient to have a monitor document for security, and the reviews of side-effects in COVID sufferers proceed to develop.
After we unpick the info and take a look at analyses of smaller teams (subgroup analyses), the one sufferers for whom profit was conclusively demonstrated have been those that have been much less severely in poor health and receiving solely supplemental oxygen slightly than being on a ventilator. It’s price remembering that ACTT-1 is a comparatively small trial and sicker sufferers could nicely profit, however it has but to be confirmed. One other attention-grabbing subgroup evaluation confirmed that sufferers receiving dexamethasone confirmed additional advantage with the addition of remdesivir, which is nice information.
A affected person receiving supplemental oxygen is more likely to profit probably the most.

No magic bullet
So once I go into my hospital this week and am confronted on the wards with sufferers who’re in poor health with COVID-19, ACTT-1 tells me that, offered I can discover remdesivir on the pharmacy shelf, I needs to be assured to make use of it in any sufferers who’re receiving oxygen alone, within the hope that they may recuperate sooner and, extra importantly, keep away from development to needing air flow on intensive care. I must also proceed to make use of dexamethasone as regular, anticipating additional advantage.
The examine additionally tells me that I mustn’t shut the doorways to the intensive care unit simply but. By prescribing remdesivir on high of making use of one of the best therapy obtainable, one in ten sufferers will proceed to deteriorate and die. Remdesivir is just not the magic bullet. If one exists, it has but to be designed.
