There is evidently a new anti-HIV agent, OPC-8212, made by Otsuka
Pharmaceuticals, Japan, about to enter clinical trials here.
It’s progress should be rapid: according to the info I heard,
it has already passed a lot of the basic toxicology stuff (phase 1)
in trials as a treatment for heart disease. It also has supposedly
had some phase 2, and even 3 trials in the US . It is licensed for that
indication in Japan. Some sharp character figured out that it is
also a potentially very effective HIV Tx. In addition to direct
anti-viral activity, it is also a down-regulator of TNF and IL-6,
thus intervening on some of the more credible immunopathological
processes in HIV disease.It is supposedly antagonistic to the
nucleosides, although that mechanism is unstated. I find it
hard to believe that this should be so for all the nukes,as the
only common point it would make sense for there to be antagonism
would be at phosphorylation, where (correct me if I am wrong)
those enzymes that are common to the phosphorylation of both
the purine and pyrimidine nucleoside analogues are also highly
necessary for all kinds of desirable processes. (2p->3p)
It is an oral drug, and trial are starting at UCLA, Cornell, and ARCA
(Atlanta). That’s what I know….Does anybody else know more?
