Eggy, see at 8:20.
Doxorubicin half-life is 35 hours, meaning half of conventional doxorubicin is still circulating nearly a day and a half after iv infusion. Faridox, because it releases doxorubicin at the site of the tumour, has extended this half-life by 40%. And that is more than ample for a working prodrug.
Exatecan half-life is 9 hours and fundamental to why it failed in the clinic, which is why Avacta needed to design a sustained release version - AVA6103.
Avacta and lab results say half-life isn't a problem for either drug. If you can't accept that, at a distance from the experiments and lab results, then what does that say about you?
Maybe you don't realise that the half-life of the pre|CISION substrate (note: not platform - that's a technique, not a chemical) is totally irrelevant in this because it is inert - uncleaved AVA6000 just leaves the body. So, not enough AVA6000 getting to the tumour to cause a suitably strong therapeutic effect? Simple. just increase the dose, which is perfectly fine as long as it's not causing dose limiting toxicity. What do you think the Phase 1a trial has been about these past few years?
