London - One of six men who fell violently ill in March during clinical trials of a new drug has been told by his doctors that he is showing early signs of cancer, a newspaper has reported.

David Oakley, 35, from London, has been told by doctors that he is showing "definite early signs" of lymph cancer, the Mail on Sunday reported.

He has also been warned that he faces the risk of multiple sclerosis, lupus, ME, rheumatoid arthritis and other illnesses.

He told the newspaper that he had an "aggressive" form of cancer and faces further tests to see what treatment is needed.

"It's very frightening. I'm trying not to be too down about the thought of having chemotherapy or that I might die," he said.

"Katrina and I had planned to start trying for children six months after getting married, but we can't do that now. Everything is on hold."

He told the newspaper that he took part in the trial to raise money for his wedding in June to wife Katrina, 29.

Oakley and the five other men had been in good health when they agreed to test a new drug for German company TeGenero AG at a clinical research unit operated by Parexel International, a US drug research company.

But they collapsed in agony, suffering from inflammation, and were rushed to hospital.

TGN 1412 -- the drug involved in the accident at Northwick Park Hospital in northwest London -- has been under development since 2000 for immunological diseases such as multiple sclerosis, rheumatoid arthritis and certain cancers.
