"Here you basically have a drug that's activated only at the tumour site"18 May 2026 20:54
I'd strongly recommend jumping to 17m44 in Part II of the Science Day Video. Now, listen carefully to all Alex Spira says, who is a lead investigator on the trial.
18m33: "Here you basically have a drug thats activated only at the tumour site, because the drug is activated only when its at the tumours.... and that's super important for lots of reasons"
"Here you basically have a drug - that's activated only at the tumour site".
How do most cancer therapies fail? The more you hit the tumour, the more you damage the patient. So the utopian scenario, is this level of precision. This is the CSO of NEXT Oncology, saying very clearly that this mechanism may solve one of the most central issues in oncology.
A quick breakdown of direct quotes around this section (Spira & Dave Liebowitz):
- "Activated only at the tumour site" which implies a cleaner therapeutic index, (i.e. potentially much less systemic exposure/toxicity)
- "We deliver a lot more of that because of the safety" - because of the localised activation, you can safely administer higher payload
- "We get really sustained inhibition of tumour growth long after the last dose" - hows that for durable anti-tumour activity and prolonged tumour exposure?
- "You can see that we get really very deep responses with AVA6103" - this is a major implication, think large tumour shrinkage
Makes sense why CC is grinning from ear to ear for the majority of the videos.
