RE: SCIB1 and iSCIB1+20 Jan 2024 16:22
Hi Chester
My take on this is that the market size for late stage unresected melanoma is $1.5 per annum currently.
Scancell's plan is to prove iSCIB1+ with the 2 CPIs and then this becomes the marketable product for unresected late stage melanoma in combination with CPIs.
However, if and when a deal is made, our partner must surely be mindful of SCIB1's monotherapy success for resected late stage melanoma in the original trial. The chances are they would want to conduct a trial with iSCIB1+ both as a monotherapy and also with CPIs for late stage resected melanoma. So that trial, if it takes place, and it is at least as successful as the original trial, would open up a second market for resected late stage melanoma.
But it may not end there, since iSCIB1+ may also be effective as a monotherapy in early stage melanona. Richard Goodfellow did state that SCIB1 was vey good at mopping up melanoma metastases. This suggests that maybe it could also be used at any stage, especially if iSCIB1+ proves to have the same lack of toxicity as SCIB1.
I wouldn't like to guess what percentage of the total melanoma market iSCIB1+ would attract.

This article suggests that the market size is expanding rapidly, possibly as a result of global warming and depletion of the ozone layer.
