According to MD Anderson We already knew that 3-BrOP was effective in preclinical research of glioblastoma, colon cancer and lymphoma & A Phase I clinical trial is planned to open this year for adult patients (this was from 2009). Also it seems its a glycolysis inhibitor. If it is then what about mitochondrial ATP? Quote | ReplyMore Sharing Services Share Share on email Share on facebook Share on twitterJcancom

It is interesting and disappointing that the optimal form of 3-BP does not appear to have yet established. The patent still needs to make broad claims for the best chemical composition. They still do not know!

Have they shown anything, or are they making claims?. Just 5 results from Pubmed, and no Phase I. I haven't read the patent in full, however cancer gets its energy two ways. They use glycolysis and mitochondrial which both produce ATP and cancer can use glutamine.

RE: Anyone used 3bp (3-bromopyruvate)?
by Jcancom on Sun May 10, 2015 06:05 PM Quote | ReplyYeah, it is very disappointing. 10 years after going through the patent process and they are still preparing for a phase 1 trial (page 4 below). How could ten years possibly be justified? 3-BrOP likely is a step-up from 3-BP- safer and more effective. Why the delay?

by Jcancom on Sun May 10, 2015 06:09 PM Quote | ReplyHow could the MD Anderson patent possibly be valid? Hopkins must have tried to sew up every possible chemical combination of 3-BP.

If it went to trial I do not know if a jury would buy the argument that 3-BrOP was sufficiently different from 3-BP to allow the patent. The claimed method of action of 3-BrOP appears to be identical to that of 3-BP.

RE: Anyone used 3bp (3-bromopyruvate)?
by Jcancom on Sun May 10, 2015 06:38 PM Quote | ReplyThe real problem might be that all of these trival variances that result in new patent claims deter companies from starting clinical trials at all. 3-BP likely is not the optimal formulation, 3-BrOP is possibly better, though not optimal. It would be hard to justify investing hundreds of millions of dollars only to be outdone by someone who made a minor modification resulting in a better product. Perhaps granting broader patent rights to all related or similar compounds with a specific therapeutic intent would give companies the protection they need to bring products like 3-BP to market.

We are now 15 years out from the first reports of 3-BP anti-cancer properties! If patent laws have really played a part in such an embarrassment, patent laws should be changed.

Maybe China would do it and do medical tourism. It is easy for doctors here to get DCA but not 3BP. Quote | Reply
