JX-594 Anti-Cancer Virus Found in Canada
Out of 23 patients, who have highly metabolized cancer, which means that the cancer has spread throughout their body and doesn’t show signs of being decreased, have been injected with a cancer fighting virus which hopes to kill the cancer cells.
This is not the first time that a cancer virus has been suggested to the public. However, normally with cancer viruses, the virus itself had to be administered and injected directly into the tumor. This is extremely difficult as, tumors are not always stationary within the human body.
The anti-cancer virus JX-594 was injected into the blood of 23 patients. 8 out of the 23 patients had the JX-594 replicating itself inside the cancer tumors, and not spreading into other healthy non-cancer cells.
"We are very excited because this is the first time in medical history that a viral therapy has been shown to consistently and selectively replicate in cancer tissue after intravenous infusion in humans.” Said, Professor John Bell, who is the lead research from the University of Ottawa.
Professor Nick Lemoine, director of Barts Cancer Institute said, “Viruses that multiply in just tumor cells - avoiding healthy cells - are showing real promise as a new biological approach to target hard-to-treat cancers.
This new study is important because it shows that a virus previously used safely to vaccinate against smallpox in millions of people can now be modified to reach cancers through the bloodstream - even after cancer has spread widely through the patient's body.
"t is particularly encouraging that responses were seen even in tumors like mesothelioma, a cancer which can be particularly hard to treat."
What happened to the other 15 patients who did not show sign of progress? Well...it’s not said. However, 6 of the patients did have infection which prevented the growth of any tumor progress. JX-594 was only given to the 23 patients at a small does, and only one does, because it is so early in the stages.
Hopefully cancer fighting viruses can continue to gain exposure and take off in our fight to kill cancer.
