RE: UPS patient29 May 2024 11:54
Just reposting this excellent piece from JT
“ The Undifferentiated pleomorphic sarcoma (UPS) patient, who I believe is likely to become the first "complete response" patient on the ava6k trial, began their ava6k treatment in Feb. 2023. Their tumours are sensitive to dox, but if they were given straight dox, they would only be allowed 6 cycles, meaning that their treatment would have ended after 18 weeks, which would have been in June or July. Progression free survival of sarcoma patients after ending their dox treatment is just 2 or 3 months (it is 6-7 months from the beginning of streatment).
Instead of progression, his tumours continue to shrink. At the November 2023 cutoff, the tumours at shrunk by 65%. By the Jan. 2024 cutoff it had shrunk to nearly 80%. So it is the fact that ava6k can be given for much longer periods that is going to be the game changer here.
Just a reminder that many tumours are sensitive to dox, but that 6 cycles is simply not enough to wipe them out. In fact, the tumours are often just starting to show significant shrinkage when the treatment stops. Precision will upend this, drastically improving response rates and improving the quality of life at the same time.”
