New Era in Cancer Treatment

Virotherapy is an effective cancer treatment that uses oncotropic and oncolytic viruses with the ability of a virus to find and destroy malignant cells in the body. Virotherapy is gentle and safe treatment, it improves survival and quality of life of patients.

Oncolytic virotherapy in the world is coordinated by the International Virotherapy Center (IVC). The mission of the IVC is to provide virotherapy treatment to every cancer patient who needs it. The main objectives of the IVC are training and certification of doctors, accreditation of medical institutions and coordination of international service of patients.

“...To treat cancer with a virus is a fantastic idea which occurred in the beginning of the last century. Before the World War I, cancer was already treated with the rabies virus vaccine and other viruses. I managed to find a virus which is not dangerous for a man. This virus can be found in intestines of healthy children. Unlike the chemotherapy and the radiation therapy, this medicine does not leave such serious consequences in patient's organs. The world began to speak in the beginning of the '90s about what I have discovered in the '70s. While reading conclusions drawn by Japanese and American scientists, I had a feeling that I am going through my own book...”

“…Cancer virotherapy is one of the most promising modern cancer therapy methods. Therefore, the leading countries in the development of pharmaceutical products have largely involved in virological researches with the aim of finding the most effective and safest viruses with the ability to selectively destroy malignant cells. Nobody doubts any more that viruses are able to do it. Just like nobody doubts any more that Latvia through Rigvir has become the leader and, at the same time, the pioneer in virotherapy. The only question is – how much time will it take until some other viral anticancer medicines will join Rigvir. Clearer and stronger with every day, virotherapy is claimed around the world as one of the firm primary therapy types, that can be more effective, safer, and patient-caring than the cancer treatment methods known until now. I will do everything that depends on me in order to develop virotherapy and help many cancer patients around the world, who have deserved such humane and effective treatment long ago…”

Ojars Sparitis, Dr.

  • President of Latvian Academy of Sciences

"It is one of the most unique Latvian scientific discoveries, which is highly valued in the world. This medicine is indicated for treatment of a very aggressive form of cancer –melanoma, after entering the human body this medicine effectively destroys cancer cells, while not harming healthy cells. The negative effects of traditional chemotherapy or radiation, as we all know, can be very destructive, as along with unhealthy cells, they destroys healthy cells as well. Virotherapy method does not have such side effects."

After more than half a decade, Latvian scientists were finally able to hit huge success as they accomplished a break-through in cancer treatment through Virotherapy techniques rather than Chemotherapy; a success which will definitely have its big trace in history as Rivgir (the first ans so far the only) will change cancer treatment methods worldwide.
