A man’s cancer vanished after he was injected with a weakened herpes virus in a promising clinical trial

Source: www.insider.com Author: Andrea Michelson A new cancer therapy that uses a modified herpes virus to attack tumor cells showed promise in early clinical trials abroad. The drug, called RP2, completely obliterated one patient's oral cancer. The 39-year-old told the BBC that he had cancer of the salivary glands, which continued to grow despite attempts at treatment. He was preparing for the end of his life when he learned about the experimental drug, which was available through a phase one safety trial at the Institute of Cancer Research in the UK. After a short course of the drug, the patient — Krzysztof Wojkowski of west London — has been cancer-free for two years and counting, he told the BBC. Other patients in the trial saw their tumors shrink, although the majority did not have a significant change: three out of nine patients who were given the trial drug alone, and seven of 30 who received a combined treatment, appeared to benefit from the experimental therapy. While more research needs to be done to see how RP2 compares to known therapies, the drug seemed to help some patients and only caused mild side effects, such as tiredness. These early results are promising, said Jonathan Zager of the Moffitt Cancer Center, who was not involved in the trial. "We'll see some more studies done in the very near future, and I'm excited — certainly not disheartened or skeptical," Zager told Insider. A modified virus delivers a 'one-two punch' to cancer cells The [...]

Herpes virus treats head and neck cancer patients

Source: www.healthcanal.com Author: staff A genetically engineered cold sore virus has been used to treat head and neck cancer patients in a Phase I/II clinical trial run by The Institute of Cancer Research (ICR) and The Royal Marsden NHS Foundation Trust. The herpes simplex virus, known as OncoVEX and owned by BioVex Inc, had been modified so it multiplies inside cancer cells but not healthy cells. It bursts and kills tumour cells and, by expressing a human protein, it also helps stimulate patients’ immune systems. The virus was injected into 17 patients’ cancer-affected lymph nodes in up to four doses, and the patients were also given radiotherapy and chemotherapy. Head and neck tumour shrinkage could be seen on scans for 14 patients (82.3%), while 93 per cent of patients had no trace of residual cancer in their lymph nodes during subsequent surgery to remove them. After an average follow-up time of 29 months (19 to 40 months), 82.4 per cent of patients had not succumbed to the disease. Only two of 13 patients given the virus treatment at a high dose relapsed. “Around 35 to 55 per cent of patients given the standard chemotherapy and radiotherapy treatment typically relapse within two years, so these results compare very favourably,” Principal Investigator Dr Kevin Harrington from the ICR and The Royal Marsden says. “This was a small study so the results should be interpreted with caution; however the very high rates of tumour response have led to the decision to take this [...]
