Maybe this is just my Western sensibilities shining through, but is there reason to trust the reporting coming from Russia? I'm genuinely interested to know if that's just my own bias or if there's something to that.

It is mostly your own bias, yes. That said publications about cancer breakthroughs ought to be taken with at least as much salt as those in western mass media.

Some information about the Russian drug from the main (I think) oncology research institute in Moscow: https://new.nmicr.ru/en/pacientam/metody-diagnostiki-i-leche...

I had a quick search and the news is apparently about results of a stage 1 trial and an earlier news article from February guessed it would take at least 2.5 years for this to become available assuming all trials were successful.

I have not found any official announcements about results of the trial, only some somewhat shady (mostly-foreign) news sites reposting each other.

According to the registry of clinical trials (https://grls.rosminzdrav.ru) the ЭнтероМикс phase 1 trials run Nov 24 - Oct 26 so I strongly suspect this is scummy clickbait reporting,
