David,
it will be really interesting to read more about development of imatinib and read their version of the story.
While reading Emperor of all maladies I was quite shocked after reading how it was developed. Making long story short it is that they did not wanted to product that drug (Dr Druker insisted and even beg them to send him some samples) because they did not saw any potential for the drug or to be more precise small market (around 180k people living in US at that time) and with huge cost of approval process.
From my side the best start is
- Emperor of all maladies - Siddhartha Mukherjee - this is one of the best book I've ever read 10/10
- Gene, an intimate history - Siddhartha Mukherjee - same author, same way of writing 10/10
