Two new drugs that inhibit the blood supply to tumours are to undergo clinical trials in humans. The combination of two drugs - angiostatin and endostatin - has been proved to eradicate all forms of cancer in mice by cutting off the blood supply to tumours. The US National Cancer Institute is to test the drugs separately for efficacy and side-effects in humans before trials of combination therapy begin. But Professor Karol Sikora from the Imperial Cancer Research Fund warns: 'There's a long way to go between the animal experiments and getting a drug that works successfully for a cancer patient each time.'
