I've done what you're doing before and the numbers become insane very quickly. I've run the numbers for predicting license and partnership valuations, which is a much more conservative prospect, and the numbers still go insane quickly. For example K at typical license structure with a 7% royalty winds up around 35 a share
Against one type cancer
Just in north America
Using royalties on sales, both at the lowest end
There are 5 more major cancers with wild or mutant p53 as primary factors. In addition to North America, there are East Asia, Oceania, and the EU with similar market potentials, which still leaves out huge regions of the world. And, six major cancers does not include even more cancers with p53 factors such as some types of leukemia.
The numbers get just ridiculously insanely huge. .
