UN: OK to use untested Ebola drugs in outbreak

The same vaccine was actually used once in 2009. It was rushed to a German lab worker who pricked her gloved finger with a needle that had contained Ebola. She survived, though it wasn't known if she was ever really infected with Ebola and if the vaccine worked.

Some experts aren't convinced, though, that any novel drugs or vaccines would make a difference in ending the current outbreak.

Once they're put to the test, most experimental drugs that seemed promising in animal studies "don't turn out to benefit people," said Dr. Jesse Goodman, former chief scientist for the US Food and Drug Administration, now at Georgetown University Medical Center.

He said some drugs prove harmful. "Unless we can ascertain that carefully, how do we really help people in the long run?"

After the two Americans received the experimental drug ZMapp, officials in Liberia requested it. Officials in Sierra Leone and Guinea have expressed interest in getting experimental treatments but haven't yet asked.

"The Liberians can count on their government, but Guineans can only count on God in the face of Ebola," said Assiatou Diallo, a nurse in Conakry, Guinea's capital.

The Spanish missionary, 75-year-old Miguel Pajares, died in Madrid's Carlos III Hospital, the hospital and his order said. A doctor who was part of the team treating the priest confirmed he had received the experimental drug. The doctor, an infectious diseases specialist, spoke on condition of anonymity, not being authorized to discuss the treatment.

Pajares' body will be cremated Wednesday to avoid any public health risks, the hospital said. He had worked for the San Juan de Dios hospital order, a Catholic group, helping to treat people with Ebola in Liberia when he became ill and was evacuated.

WHO said the size of the outbreak - the first in West Africa - made the experimental use of drugs ethical even though there is no evidence they work and it is possible they could be dangerous. The agency convened an expert panel of ethicists, infectious disease experts and patient representatives to discuss the issue on Monday.

"We don't have enough people to rely on the traditional methods if we want to stop the outbreak as soon as possible," Kieny said.

WHO said it was OK to use unproven treatments or vaccines if patients give their informed consent and are guaranteed confidentiality and freedom of choice.

There was no specific advice on who should get them; the panel only said more analysis and discussion was needed.

"I don't think there could be any fair distribution of something available in such small quantities," Kieny noted.

She said some companies were speeding up trials of their new Ebola vaccines and there might be some preliminary safety data by the end of the year.

WHO also said the world had "a moral duty" to collect evidence about the safety and effectiveness of Ebola treatments in scientific trials.

Canada's Tekmira Pharmaceuticals Corp. is developing a drug that targets Ebola's genetic material. The FDA had halted a small safety study with questions about a reaction in healthy volunteers. Last week, Tekmira announced that the FDA had modified its restriction, clearing a roadblock to possible experimental use in patients, and said it was "carefully evaluating options."

West African nations are struggling to control both the deadly outbreak and the fear it has created. Some airlines flying in and out of the region have suspended flights.

The Cote d'Ivoire, which shares borders with Liberia and Guinea, banned direct flights from those countries and said it would increase health inspections at its borders. Guinea-Bissau also announced it was temporarily closing its border with Guinea because of the Ebola outbreak.

On Tuesday, Liberian President Ellen Johnson Sirleaf suspended all travel by executive branch officials for one month. She also ordered those already abroad to return home within a week "or be considered as abandoning their jobs," according to a statement.
