Covid-19: WHO suspends remdesivir from list of medicines

WHO advises against Gilead's remdesivir for all hospitalised Covid-19 patients

Gilead's remdesivir is not recommended for patients hospitalised with Covid-19, regardless of how ill they are, as there is no evidence the drug improves survival or reduces the need for ventilation, a World Health Organization panel said on Friday.

"The ... panel found a lack of evidence that remdesivir improved outcomes that matter to patients," the guideline said.

"Especially given the costs and resource implications associated with remdesivir ... the panel felt the responsibility should be on demonstrating evidence of efficacy, which is not established by the currently available data," it added.

The advice is another setback for the drug, which grabbed worldwide attention as a potentially effective treatment for Covid-19 in the summer after early trials showed some promise.

The antiviral, known by the brand name Veklury, is one of only two medicines currently authorised to treat Covid-19 patients across the world. But a large WHO-led trial known as the Solidarity Trial showed last month that it had little or no effect on 28-day mortality or length of hospital stays for Covid-19 patients.

The medication was one of the drugs used to treat U.S. President Donald Trump's coronavirus infection, and had been shown in previous studies to have cut time to recovery. It is authorised or approved for use as a Covid-19 treatment in more than 50 countries.

Gilead has questioned the Solidarity Trial's results and said in a statement on Friday it was "disappointed" at the new WHO guideline.

"Veklury is recognised as a standard of care for the treatment of hospitalised patients with COVID-19 in guidelines from numerous credible national organisations," it said.

"The WHO guidelines appear to ignore this evidence at a time when cases are dramatically increasing around the world and doctors are relying on Veklury as the first and only approved antiviral treatment for patients with COVID-19."

The WHO advice raises questions about whether the European Union will need the 500,000 courses of the antiviral, worth 1 billion euros ($1.2 billion), it ordered last month.

Italy's drugs regulator, AIFA, said it had been "stressing for weeks the modest effectiveness of remdesivir".

"In practice we have been saying for some time that it is not use for much," the regulator said.

No meaningful effect

The WHO's Guideline Development Group (GDG) panel said its recommendation was based on an evidence review that included data from four international randomised trials involving more than 7,000 patients hospitalised with COVID-19.

After reviewing the evidence, the panel said it concluded that remdesivir, which has to be given intravenously and is therefore costly and complex to administer, has no meaningful effect on death rates or other important outcomes for patients.

Peter Horby, a professor of emerging infectious diseases at Britain's Oxford University, said the WHO's new advice should prompt "a rethink about the place of remdesivir in COVID-19".

"Remdesivir is an expensive drug that must be given intravenously for five to 10 days, so this recommendation will save money and other healthcare resources," he said.

At the end of October, Gilead cut its 2020 revenue forecast, citing lower-than-expected demand and difficulty in predicting sales of remdesivir.

The fresh advice also comes after one of the world's top bodies representing intensive care doctors said remdesivir should not be used for COVID-19 patients in critical care.

The recommendation, which is not binding, is part of its so-called "living guidelines" project, designed to offer ongoing guidance for doctors. The panel added that it supported continued enrolment into clinical trials evaluating remdesivir in patients with COVID-19, which it said should "provide higher certainty of evidence for specific groups of patients".

The WHO said on Friday it has suspended Gilead's remdesivir from its so-called prequalification list, an official list of medicines used as a benchmark for procurement by developing countries, after issuing guidance against its use in hospitalised Covid patients.

"Yes we have suspended it from the PQ (prequalification list)," Tarik Jasarevic said in an emailed response to Reuters. "The suspension is a signal to countries that WHO, in compliance with the treatment guidelines, does not recommend countries procure the drug for COVID."

He added that the WHO was not aware that any international procurers were providing the drug to low- and middle-income countries.
