RE: The Issue Here28 Feb 2023 11:45
BITL - I agree - the presentation gave a lot of additional data and narrative about that particular table. There are number of issues in comparing the two sets of data (end stage vs primary treatment as just one example, but additional mitigation treatment would undoubtedly be used in primary treatment, so the data presented there could be artificially low if it wasn't also used with AVA6K). Saunders did issue caution about comparing the data and I would have like to ask a number of questions I have about the data presented about side effects, but what absolutely clear is that even with dose increases, we are not seeing the toxicity that prevents longer treatment with powerful doxirubicin. Don't forget that it is cleavin and dox is being deposited in the tumour significantly more so than the blood. Ideally there would be nothing in the blood, but given there is bloodflow all round the body including the tumour, then it is no supply that there is a small amount in the blood and potentially causing some side effects but at a significantly lower level.
Additionally, the tumour types are interesting. There are two patients with tumour types where dox is standard care... and at least one patient has had 8 cycles. I'm not sure if I was on a trial at end stage that I would go through 8 cycles if there was not some evidence that it was productive. Speculative, but not unreasonable to feel positive about that.
