A number of COVID medicine are within the pipeline for 2022, some you may doubtlessly take at house, others to be used in hospital.
It’s taken virtually two years of the pandemic to get right here.
Nevertheless, as we argue in our paper, with extra and bigger collaborations, and specializing in repurposing the fitting medicine, we may have developed efficient COVID medicine at scale, earlier.
Right here’s what we are able to do higher for the following pandemic.

First, some excellent news
One current research discovered a generally prescribed drug for melancholy, fluvoxamine, given to folks recognized with COVID-19 decreased their likelihood of signs deteriorating, needing to go to hospital, and dying.
There are 4 highly effective options of this research. It was based mostly on:
an present human drug: medicine designed for an additional goal can have further therapeutic advantages. We additionally didn’t should design a drug from scratch and knew loads about tolerated doses, side-effects and drug interactions, over a few years of individuals taking it
earlier statement and knowledge: the drug was chosen based mostly on prior knowledge displaying folks taking the identical or comparable medicine for melancholy did higher with COVID-19 an infection
a big inhabitants: the research included sufficient folks to present significant outcomes
a world collaboration: it’s unclear why have been there not many, thorough, research of this kind carried out on the very begin of the pandemic. Collaboration helps with faster recruitment and broader enter into trial design.
Nevertheless, this instance is the exception quite than the rule on the subject of discovering COVID medicine. And through the pandemic, we’ve had a number of mis-steps.

We missed an early alternative
We are able to deal with COVID with one in every of two broad methods. One is to focus on or immobilise the virus itself. The opposite is to “deal with the host”. This entails treating the physique’s overwhelming response to the virus and the reason for most dying and illness. Fluvoxamine talked about above is an instance of the latter.
Nevertheless, we didn’t see any main technique to “deal with the host” within the early a part of the pandemic, besides with the decades-old corticosteroid medicine dexamethasone and budesonide.
Focusing extra on “treating the host” would have purchased us time to supply vaccines and antiviral medicine, which usually take longer to develop.
“Treating the host” is hardly radical. We’ve been doing this with present medicines for infectious illnesses for years.
In reality, we knew early on that we reply to COVID-19 in a lot the identical solution to being contaminated with different viral infections that may overwhelm the physique, comparable to influenza and Ebola.
That’s not the one mis-step.
We backed just a few flawed horses
It’s inevitable some present medicine trialled initially for COVID-19 would fall by the wayside and by no means be used clinically. However we backed among the flawed medicine, on the flawed doses. Based on primary analysis and scientific data of how medicine work within the physique, this could have been apparent from the beginning.
Over a century after medical doctors unsuccessfully tried to deal with the Spanish flu with quinine and its derivatives, historical past was repeating itself. We have been asking if the associated drug hydroxychloroquine could possibly be used to deal with COVID-19.
Researchers world wide carried out a number of trials with hydroxychloroquine, even after some others reported an absence of efficacy.
Within the first 12 months of the pandemic, hydroxychloroquine was examined in about 250 research involving practically 89,000 folks, regardless of proof it doesn’t assist.
If we’re to repurpose present medicine, this must be based mostly on our expertise of that drug in people with COVID-19, comparable to within the fluvoxamine instance. Alternatively, the drug wants to suit with what we find out about how the virus causes illness and the way the an infection develops in people.
If we’re to repurpose medicine recognized solely on cell-based laboratory research, this should even be based mostly on what we find out about how the human physique handles the drug and the way the drug works within the physique. We additionally want the related high quality mathematical fashions to get the dose proper for the early part human research.
Utilizing such primary approaches to drug improvement, which we’ve identified about for years, we may have foreseen that ivermectin and hydroxychloroquine would show to be ineffective – earlier than bigger scale human trials have been ever allowed to be carried out.

We additionally backed too many small trials
Through the pandemic, there have been an estimated 2,800 scientific trials for COVID medicine with fewer than 300 reported.
In a single database of COVID-19 trials, 40% stated researchers have been enrolling fewer than 100 sufferers, a pattern dimension usually too small to be helpful.
For us to get a greater thought if a COVID drug is secure and efficient, we’d like bigger, collaborative trials.
For instance, the RECOVERY trial
enrolled about 45,000 folks at 180 websites to check a variety of potential COVID therapies. It confirmed the repurposed drug dexamethasone decreased dying charges, altering commonplace apply.

How may we do higher subsequent time?
We have to begin desirous about methods of growing medicine for the early a part of the following pandemic, contemplating what we’ve discovered from this one.
That is important if we’re to have a variety of secure, efficient, low-cost and accessible therapies for treating the host, to purchase time to develop vaccines and antivirals.
We now know from world experiences the significance of rational alternative of medication for testing. We additionally know the significance of enormous scientific trials that come from main, worldwide collaborations.
We additionally must co-ordinate analysis efforts nationally, quite than compete for analysis {dollars} with different teams. Doing analysis in a pandemic is just not like doing analysis in non-pandemic occasions. So this implies international locations comparable to Australia must have their very own centre for pandemic preparedness or centre for illness management to co-ordinate analysis and funding priorities.
