Following WHO recommendations against the use of hydroxychloroquine in the prevention of COVID-19, including its use in controlled trials, we are reviewing the guideline and available evidence. We are concerned that this judgement from the authors of the guideline is scientifically unsound.

In the next few months, the first Phase 3 COVID-19 vaccine trials – the majority of them in upper-middle or high-income countries and in specific target populations like young adults – will report their results. How relevant will their study results be for low-resource settings?

Hydroxychloroquine doses in COVID-19 prevention trials should be safe, study finds. Now let’s find out if they’re effective.

COPCOV COVID-19 MORU Bangkok Research

As the world waits impatiently for a COVID-19 vaccine, an exhaustive review of hydroxychloroquine and chloroquine pharmacology suggests that the doses used in COVID-19 prevention trials are safe, say University of Oxford affiliated researchers in a study published in PLoS Medicine.

Hydroxychloroquine is being discarded prematurely in COVID-19 prevention

COPCOV COVID-19 MORU Bangkok

Hydroxychloroquine could still prevent COVID-19 and save tens of thousands of lives around the world, say leading scientific researchers. While it doesn’t work in treatment of hospitalised patients, it could still prevent infections. However, fraudulent data, unjustified extrapolation and exaggerated safety concerns together with intense politicisation and negative publicity may stop COPCOV, the only large, global clinical trial testing hydroxychloroquine in COVID-19 prevention, from ever finding out.

UK regulator gives green light to clinical trial of hydroxychloroquine to prevent Covid-19 in healthcare workers

COPCOV COVID-19 MORU Bangkok

The UK regulator MHRA announced on 26 June that it would again permit recruitment to the COPCOV COVID-19 prevention clinical trial. The MHRA decision came 5 weeks after it reacted immediately to the now-discredited paper published in The Lancet suggesting harms with hydroxychloroquine, and paused recruitment of UK participants. But The Lancet paper was based on fabricated data and was swiftly retracted. After this interruption, recruitment around the globe to COPCOV can now resume.

COVID-19 prevention and treatment: a critical analysis of chloroquine and hydroxychloroquine clinical pharmacology

COPCOV COVID-19 MORU Bangkok Publication

Paper by NJ White et al, PLoS Medicine, in press. Using available pharmacokinetic information from healthy volunteers, the treatment of malaria, the chronic treatment of rheumatological conditions and the toxicokinetics of chloroquine in self-poisoning, the authors predict exposures and safety margins in the high dose chloroquine and hydroxychloroquine COVID-19 prevention and treatment regimens currently under evaluation. These regimens are predicted to have reasonable safety margins. Large, well conducted randomised clinical trials with appropriate monitoring are required to determine if chloroquine and hydroxychloroquine have preventive or treatment efficacy in COVID-19 and acceptable safety. Current recommendations for their use outside of clinical trials are not justified at this time.
