The
doctor who had been leading Sierra Leone’s battle against the Ebola
outbreak was now fighting for his own life, and his international
colleagues faced a fateful decision: whether to give him a drug that had
never before been tested on people.
Would the drug, known as ZMapp,
help the stricken doctor? Or would it perhaps harm or even kill one of
the country’s most prominent physicians, a man considered a national
hero, shattering the already fragile public trust in international
efforts to contain the world’s worst Ebola outbreak?
The
treatment team, from Doctors Without Borders and the World Health
Organization, agonized through the night and ultimately decided not to
try the drug. The doctor, Sheik Umar Khan, died a few days later, on
July 29.
The doses of the drug that were not used were eventually sent to
Liberia, where other doctors made the opposite decision — and two
American aid workers became the first people in the world to receive
ZMapp. Both of them survived and are now being treated at Emory
University Hospital in Atlanta.
“It’s
a little political; that’s what it looks like to me,” Alhajie Khan, Dr.
Khan’s brother, said of the decision. “Why would you not give it to
him? The guy who helped all of these people.”
The provision of ZMapp, which is in extremely limited supply, to foreign aid workers has raised broad ethical questions
about the disparities in treatment between white outsiders and the
Africans who form the overwhelming majority of victims in the epidemic.
Those
concerns were heightened further after Spanish officials confirmed that
they had obtained a supply of ZMapp for a third patient, a 75-year-old
Spanish priest who died Tuesday after having been evacuated to Madrid
from Liberia.
The
previously untold story of Dr. Khan, recounted by two doctors involved
in discussions about whether to use ZMapp, offered an unusual glimpse
into the wrenching ethical dilemma of when and how experimental drugs
should be used to combat the Ebola epidemic in West Africa. Had the
treatment team decided differently in his case, the first person treated
with the drug would have been African.
On
Tuesday, the World Health Organization endorsed the use of untested
drugs to combat the outbreak, which has already killed more than 1,000
people and continues to spread. But ZMapp and other potential treatments
are in such short supply that another politically charged question
remains: Who should get them?
What You Need to Know About the Ebola Outbreak
Marie-Paule
Kieny, assistant director general of the World Health Organization,
said at a news conference in Geneva on Tuesday that several drugs and
vaccines had shown some promise in animal testing and might conceivably
be used.
But
none are “available in unlimited supplies right now,” Dr. Kieny said.
“I don’t think that there could be any fair distribution of something
which is available in such a small quantity.”
On
Tuesday, Liberia’s government announced that it would receive ZMapp
after its president, Ellen Johnson Sirleaf, requested the drug from the
United States. It said the drug would be used to treat two doctors who
have Ebola.
That would be the first known use of the drug to treat Africans, but it also might be the last for a while. The manufacturer, Mapp Bio-pharmaceutical,
said that it had complied with a request from a West African nation,
but noted in a statement that the available supply of the drug was now
exhausted.
In the case of Dr. Khan, who has been called “the arrowhead
of the fight” against Ebola in his country, the doctors involved said
there was no intention to save the drug for Americans. They said it was
not known that the American aid workers were sick at the time of the
decision not to treat Dr. Khan, around July 23. Instead, they said,
doctors feared stoking the considerable suspicion of Western medical institutions in the country, which was already making it harder to contain the outbreak.
“What
they really didn’t want to do was kill Dr. Khan with their attempt at
therapy,” said Dr. Armand Sprecher, a public health specialist at
Doctors Without Borders. “If word got out that M.S.F. killed Dr. Khan,
that would have implications for outbreak control,” he added, using the
initials for the French name of the relief group.
Dr.
Sprecher, who is involved in the procurement and use of drugs for
Doctors Without Borders but was not directly treating Dr. Khan, said
another factor was that Dr. Khan’s virus levels were so high it was
believed the drug would probably not work.
He
said the treatment team never discussed the option of using the drug
with Dr. Khan himself, deciding it would do so only if it decided to go
ahead with the treatment.
“There
are an awful lot of people who are very traumatized by the whole
event,” Dr. Sprecher said in a telephone interview from Brussels on
Tuesday.
At
the time the decision was made, less was known about ZMapp, which may
have helped the two American relief workers, Dr. Kent Brantly and Nancy
Writebol, who were initially treated in Liberia and then evacuated.
