A federal oversight agency suspended almost all of Johns Hopkins federally financed medical research involving human subjects. The NewsHour Health Unit is funded by a grant from The Henry J. Kaiser Family Foundation. |

Earlier this week, Hopkins officials concluded their own investigation, saying the university's researcher had not adequately checked for problems with the compound, called hexamethonium. Hopkins also found that the researcher had not warned Roche properly about the chemical's risks.
RAY SUAREZ: Hopkins is not the first university to be punished for safety lapses. In recent years, several other universities, including the University of Pennsylvania and Georgetown University, have been sanctioned by the government, and because of broader concerns, the National Bioethics Advisory Commission recently recommended an overhaul of safeguards to protect human research. |

RAY SUAREZ: For more, we turn to Dr. Edward Miller, dean and CEO of Johns Hopkins Medicine at Johns Hopkins University, and Ernest Prentice, associate vice chancellor for academic affairs and regulatory compliance at the University of Nebraska Medical Center.
DR. EDWARD MILLER: Well, OHRP issued their findings on Thursday at noon, and essentially there was no process in place to address the issues. I contacted the Secretary of Health, Education, and Welfare, Tommy Thompson. He responded to me this morning. We now have a process in place where OHRP and Hopkins are working diligently tonight, as a matter of fact, to have a corrective action plan that will allow full accreditation of Hopkins' research very shortly. RAY SUAREZ: Well, given what the government body had to say about your institution's work in this research project, and what your own internal investigations have turned up, what can you tell us about how Ellen Roche died?
RAY SUAREZ: Vice Chancellor Prentice, you've seen some of the documents involved in this case, and you've overseen research projects yourself. Was this an appropriate action on the part of the Department of Health and Human Services? ERNEST PRENTICE: Well, I also serve as a compliance consultant to OHRP, and I've been on ten for-cause compliant site visits, 20 percent of which have resulted in shutdowns. So the action taken by OHRP is consistent with the kinds of actions they have taken in the past at institutions where they felt that there were deficiencies in their program for protection of human subjects. RAY SUAREZ: But when you find a flaw like this in one particular research project, why not just shut that one down? Why close down the entire range of work that an institution is doing?

RAY SUAREZ: Dr. Miller, let's look at the particular case of this asthma research. A compound was introduced to several test subjects' bodies, not to test that compound necessarily, if I understand this right, but to cause a reaction which would help you understand the way the body works better. Was there a problem with using this particular substance? DR. EDWARD MILLER: Well, this substance had been used in the past, in the 1950s, to treat patients with severe hypertension, given both orally and intravenously. The substance itself had been given to 20 volunteer subjects at four different institutions to look at lung studies, and there's a vast literature, in Russia, for example, using this drug to control hypertension. So this was not a substance that was totally unknown. It was taken off the market in 1972 by the FDA, and it was taken off the market not because of complications, but because that there were new and better agents that could lower blood pressure. RAY SUAREZ: But hexamethonium was not approved by the FDA for the use that you were using it for at Johns Hopkins. By calling it a medication in the consent form, did you perhaps create an impression in your volunteers about what was about to happen to them that you may do differently today?
RAY SUAREZ: Well, Vice Chancellor Prentice, maybe you can help us out a little bit there. When you're using something in what's called a challenge study-- that is, introducing a substance to get a reaction-- is there a different kind of protocol, a different kind of set of rules from when you are using something that is in itself being explored as a treatment or a therapy? ERNEST PRENTICE: Well, in terms of the application of the regulations, there really is no difference. We would characterize the protocol that Ellen was enrolled in as a non-therapeutic research protocol, meaning that there is no direct benefit to the individual subject. RAY SUAREZ: And when someone is involved in a test of that kind, when they are subjecting themselves to something from which they are likely to derive no benefit, is there a different set of rules that play there from, let's say, sick people who are trying experimental procedures in the hopes of getting well? ERNEST PRENTICE: Well, the rules are really not different. The IRB must determine that there is an acceptable risk- benefit relationship of the research, and basically it means that the societal benefit, in terms of an advancement of knowledge, must at least outweigh or balance the risk associated with the research. On the other hand, in therapeutic research or clinical research there's often benefit to the patient that can help balance out the risks. RAY SUAREZ: And from what you know about this case, do you think the risk-benefit ratio was in proper relationship?
RAY SUAREZ: When you use volunteers, Dr. Miller, is there really any way that you can fully inform them of every possibility, every downside that might occur in a clinical trial? Can we reduce risk to zero? DR. EDWARD MILLER: Well, I think everybody's goal would be to try to reduce it to zero, but human variability will probably not allow us to do that. As an anesthesiologist, for example, I give drugs to people. I'm not quite sure what their reaction is going to be, because everybody is a little bit different. I try to minimize the risk, but I cannot be 100 percent sure that I have minimized it to zero. The important thing in this case, I think, is that ten million people in this country have asthma; it is a condition that is getting worse all the time; and, importantly, hundreds of people in this country die from asthma every year. |

RAY SUAREZ: So if you're looking at perhaps a pause in this work rather than a complete cessation, might it provide the necessary breather to get things in order that you need to get in order at Johns Hopkins? I mean, is there some work that you can do during this suspension that might work to the benefit of future patients? DR. EDWARD MILLER: Well, as I said, we are probably more concerned about the welfare of patients than anyone. We're the ones who care for those patients on a daily basis, and patients come to us for it. We will comply fully with the OHRP to try to make sure any of the issues that they have with us are resolved as quickly as possible. I will point out, however, that on October 3, the OHRP sent us a letter addressing some of their concerns. We set up a second IRB group to review protocols, we did a variety of things, and we responded in writing to them on December 28, and we assumed from our December 28 letter that we were fully compliant. It was a little bit surprising that in seven months we have not heard from them that they did not feel that we were doing an adequate job in protection of human subjects. RAY SUAREZ: Those IRBs, or institutional review boards, are made up of people who work at Hopkins? DR. EDWARD MILLER: They are made up of some people that work at Hopkins, but also there's lay public involved. RAY SUAREZ: Do you think that they are uniformly able, in the various institutions that they're working in across the country, to do the work that they are charged to do or might the IRB system need a look?
RAY SUAREZ: And Vice Chancellor Prentice, on that same subject, is this a Hopkins' problem or a problem that we see with the system with research oversight? ERNEST PRENTICE: No, it's not a Hopkins' problem; it's a universal problem. We know from a number of different studies that IRBs have been chronically overloaded and under resourced. So there is a problem out there. I think it's gradually being corrected, but it's going to take some time. There are currently plans to have an IRB accreditation system in place. However, we're talking about thousands of IRBs potentially being accredited, so it's going to take some time to develop the infrastructure to accomplish that goal. RAY SUAREZ: And in the meantime, does work, the kind of work that was being done on asthma at Johns Hopkins, does that have to slow down or stop? Can we do this while the car is rolling, sort of repair it on its way?
RAY SUAREZ: And Dr. Miller, do you think that you can be back in business quickly? DR. EDWARD MILLER: Oh, I certainly do, and I think we do have an excellent program. We can always make improvements. We will strive to make those improvements, but again, I think it has to be recognized: We have treated literally thousands of patients under protocols here at Hopkins; we have had one death in one human healthy subject in over a hundred years of study-- a pretty good track record, not perfect; I wish it were perfect; but we do take it very seriously, the safety and welfare of patients that come to us. RAY SUAREZ: Gentlemen, thank you both. DR. EDWARD MILLER: Thank you very much. ERNEST PRENTICE: Thank you. |
