Report assails FDA oversight of clinical trials
Federal investigator says little done to ensure patient safety
WASHINGTON - The Food and Drug Administration does very little to ensure the safety of the millions of people who participate in clinical trials, a federal investigator has found.
In a report released Friday, the inspector general of the Department of Health and Human Services, Daniel R. Levinson, said federal health officials did not know how many clinical trials were being conducted, audited fewer than 1 percent of the testing sites and, on the rare occasions when inspectors did appear, generally showed up long after the tests had been completed.
The F.D.A. has 200 inspectors, some of whom audit clinical trials part time, to police an estimated 350,000 testing sites. Even when those inspectors found serious problems in human trials, top drug officials in Washington downgraded their findings 68 percent of the time, the report found. Among the remaining cases, the agency almost never followed up with inspections to determine whether the corrective actions that the agency demanded had occurred, the report found.
“In many ways, rats and mice get greater protection as research subjects in the United States than do humans,” said Arthur L. Caplan, chairman of the department of medical ethics at the University of Pennsylvania.
Animal research centers have to register with the federal government, keep track of subject numbers, have unannounced spot inspections and address problems speedily or risk closing, none of which is true in human research, Mr. Caplan said.
Enforcement needs more 'teeth'
Because no one collects the data systematically, there is no way to tell how safe the nation’s clinical research is or ever has been.
The drug agency oversees just the safety of trials by companies seeking approval to sell drugs or devices. Using an entirely different set of rules, the Office for Human Research Protections oversees trials financed by the federal government.
Privately financed noncommercial trials have no federal oversight.
“It’s crazy that we have all these different sets of rules,” said Dr. Ezekiel J. Emanuel, chairman of the bioethics department at the National Institutes of Health. “It would facilitate things a lot if we had one agency overseeing things.”
Dr. Janet Woodcock, chief medical officer at the drug agency, acknowledged that it needs to put more “teeth” in its enforcement. “We are working to address these problems very aggressively,” Dr. Woodcock said.
The case of Audine Graybill demonstrates the flaws in the system. According to the F.D.A., in the spring of 2005, she decided to try an experimental drug to treat mania associated with bipolar disorder. The consent form that she signed on May 29 stated that she could change her mind at any point in the study.
She checked into High Pointe Healthcare in Oklahoma City, a psychiatric center owned by a psychiatrist, Dr. David Linden. On June 3, Ms. Graybill changed her mind and asked to leave.
Dr. Linden refused to let her go.
On June 6, she was given the experimental medicine. Ms. Graybill’s lawyer, Anthony Sykes, obtained a writ of habeas corpus for her to appear in court and took the writ to the hospital, where the staff refused to honor it and said it would not give it to Dr. Linden, Mr. Sykes said.
Mr. Sykes tracked Dr. Linden to another office and had him served with the writ, Mr. Sykes said. Within hours, Dr. Linden’s lawyer called Mr. Sykes and said Ms. Graybill was free to go. Mr. Sykes took her home on June 7.
Ms. Graybill could not be reached.
More than nine months later, an F.D.A. inspector appeared at Dr. Linden’s research center and uncovered myriad other problems.
The agency sent its warning letter more than two years after Ms. Graybill’s experience.
Last November, the Oklahoma Board of Medical Licensure and Supervision suspended Dr. Linden’s license for three months because he had sex with two patients and gave them genital herpes infections, according to board records. Dr. Linden, who also owns a psychiatric center in Las Vegas, did not return repeated telephone messages.
Dr. Linden has conducted clinical trials for most major pharmaceutical companies and continues to do research, according to his Web site.
The F.D.A. disqualified investigators from conducting further clinical trials 26 times from 2000 to 2005 and disqualified their data just twice even though the agency found serious problems at trial sites 348 times in that period, the inspector general found.
While some of the report’s findings surprised ethicists, its conclusion that the agency’s oversight of clinical trials is disorganized and underfinanced has long been known and is, in many ways, identical to criticisms leveled at other agency functions, including its oversight of imported food, foreign drug manufacturers, animal food and the safety of older medicines.
