Yet the CAFE study was not without risks. It barred subjects from being taken off their assigned drug; it didn’t allow them to be switched to another drug if their assigned drug was not working; and it restricted the number of additional drugs subjects could be given to manage side effects and symptoms such as depression, anxiety, or agitation. Like many clinical trials, the study was also randomized and double-blinded: Subjects were assigned a drug randomly by a computer, and neither the subjects nor the researchers knew which drug it was. These restrictions meant that subjects in the CAFE study had fewer therapeutic options than they would have had outside the study.
In fact, the CAFE study also contained a serious oversight that, if corrected, would have prevented patients like Dan from being enrolled. Like other patients with schizophrenia, patients experiencing their first psychotic episode are at higher risk of killing themselves or other people. For this reason, most studies of antipsychotic drugs specifically bar researchers from recruiting patients at risk of violence or suicide, for fear that they might kill themselves or someone else during the study. Conveniently, however, the CAFE study only prohibited patients at risk of suicide, not homicide. This meant that Dan—who had threatened to slit his mother’s throat, but had not threatened to harm himself—was a legitimate target for recruitment.When Mary found out that Dan had been recruited into the CAFE study, she was stunned. “I do not want him in a clinical study,” she told Olson. Just a few days earlier, Olson indicated in a petition to the court that Dan was both dangerous and mentally incapable of consenting to antipsychotic medication. How could he now be capable of consenting to a research study with the very same antipsychotics—especially when the alternative was commitment to a state mental institution?
After Dan was enrolled, he stayed at Fairview for about two more weeks. By that point, Olson thought Dan’s symptoms were under control, but Mary was still very worried by his erratic behavior. She recalls meeting with the doctor: “Olson came in and sat down and opened his file and said, ‘Oh, Dan is doing so well.’ And I said, ‘No, Dr. Olson, Dan is not doing well.’ I think he was taken aback.” Even so, on December 8, 2003, Dan was transferred to Theo House, a halfway house in St. Paul. He was required to sign an agreement confirming that he understood he could be involuntarily committed if he didn’t continue taking his medication and keeping his CAFE study appointments.
