Amidst news from Spain that a 75-year-old Catholic priest has received the experimental treatment ZMapp for Ebola, Art Caplan critiques what he describes as the “bad science” behind choosing its recipients:
ZMapp is not the answer to the Ebola epidemic ravaging West Africa. There is no chance of getting a significant amount of this drug made for many months. Deploying more health care workers, face guards, moon suits, gloves and antiseptic, along with restrictions on travel and burying the dead, is the only way to get the epidemic under control. [...]
The fact that a 75-year-old has been given the scarce drug is especially disturbing, not because he is 75 but because 75-year-olds do not have strong immune systems — something very important in battling a virus like Ebola. Moreover 75-year-olds often have other medical problems that complicate the ability of scientists to figure out if the drug is safe and if it is really working.
In testing unapproved, highly risky drugs like ZMapp, it is crucial that recipients not be so sick that they may well die regardless of whether they get the drug or not. Indeed, the recipients ought not be very sick so that side-effects can be seen and efficacy determined. To do that, doctors need to be able to monitor experimental subjects for months to make sure the drug does not damage their livers or cause any other fatal side-effect. So not every person infected with Ebola makes for the best recipient — younger, those more recently infected and those who can be closely monitored are among the “best” candidates.
