Over the last two Mondays, I've been writing about an unproven cancer therapy that I hadn't really heard much about before. The cancer treatment is called Rigvir; it is manufactured in Latvia and marketed primarily through a Latvian entity called the International Virotherapy Center (IVC).
To recap, Rigvir is an unmodified Echovirus, specifically ECHO-7, that, according to the IVC, seeks out cancer cells, replicates in them, and thus lyses the cancer cells (causes their membranes to break, spilling out the cancer cells contents, thus killing the cell), hence the term "oncolytic virus."
Somehow, mysteriously Rigvir was approved by the Latvian equivalent of the FDA in 2004 for the treatment of malignant melanoma despite what appears to have been grossly inadequate supporting evidence and then even more mysteriously placed on the Latvian Health Ministry's list of reimbursable medications in 2011. I suspect that the reason that I didn't look into Rigvir earlier was probably because its use had been primarily restricted to Latvia, Georgia, and Armenia. Also, there was the language barrier.
