We recently posted Elephant Man drug trial victim showing signs of cancer, about a horrific ordeal involving six healthy young men who volunteered at Northwick Park Hospital, in London as participants in a clinical trial for a drug called TGN1412, designed to treat leukemia, autoimmune and inflammatory diseases.

According to the men, they were told by doctors there would be no serious short-term or long-term side effects from participating in the drug trial. That wasn't the case. The participants were misled regarding the safety of the experimental drug -- everything went terribly wrong -- and one of the six men has now been told he is showing signs of cancer.

Another egregious event has occurred on the other side of the pond, according to news of an allegation made by a woman who claims she was used as an experimental cancer drug guinea pig without consent.

The story began last year when Trelene Cave was diagnosed with ovarian cancer. Treated at Epsom General Hospital and the Royal Marsden Hospital in Sutton, she was later sent to St George's Hospital for a second opinion before undergoing an operation. The trouble begins when St George's Hospital doctors allegedly treated Cave with Scotroc4, an experimental cancer drug, without her informed consent. She developed a blood clot and almost died.

Cave states in the news report that, "I trusted them totally. Nobody discussed it with me. I just can't understand it."

St George's Healthcare Trust has apologized to her and her husband Norman for the incident. An investigation has been called for into whether St George's Hospital doctors side-stepped ethical guidelines in treating Cave without her knowledge.
