The World Health Organisation declared on Monday that Ebola can no longer be called an incurable disease, after two of four drugs being trialled in the major outbreak in the Democratic Republic of the Congo were found to have significantly reduced the death rate.
“From now on, we will no longer say that Ebola is incurable,” said Prof Jean-Jacques Muyembe, the director general of the Institut National de Recherche Biomédicale in DRC, which has overseen the trial. “These advances will help save thousands of lives.”
The successful drugs are two monoclonal antibodies which have reduced mortality rates in the ongoing trial by the World Health Organization and the US National Institute of Allergy and Infectious Diseases (US NIAID)
ZMapp, used during the massive Ebola epidemic in Sierra Leone, Liberia and Guinea, has been dropped along with Remdesivir.
Anthony Fauci, the director of the US NIAID, said the overall mortality of those given ZMapp in the trial in four centres was 49% while that of Remdesivir was 53%. A monoclonal antibody drug made by Regeneron had the lowest overall death rate, at 29%, while the monoclonal antibody 114 made by Ridgeback Biotherapeutics had a mortality rate of 34%.
But the results in people who arrived at a treatment centre soon after they became sick, rather than staying at home, were even more impressive – with death rates of 24% on ZMapp, 33% with Remdesivir, 11% with 114 and just 6% with Regeneron’s drug.
“Now that 90% of their patients can go into the treatment centre and come out completely cured, they will start believing it and building trust in the population and community,” he said.
One of the biggest obstacles in fighting the year-long DRC outbreak, the second biggest ever and now with 2,800 cases, has been the reluctance of those who fall sick to seek treatment.
On average, people who fall ill are not turning up at a treatment centre for four days, said Dr Michael Ryan from the WHO. This reduces their chances of survival and makes it likely that the virus, spread through bodily fluids, will be transmitted to their families.
“The numbers might change,” said Fauci. “Not all the data has been accumulated.” The two monoclonal antibodies will both now be used in every treatment centre in DRC.
Fauci paid tribute to all of those involved in the trial in four towns: Beni, Katwa, Butembo and Mangina. NGOs including International Medical Corps and Médecins Sans Frontières “put their lives on the line every day to care for patients in extremely difficult conditions in the area where the outbreak is occurring,” he said.
