Yeah... BigP factors in research cost into the final price of the pill. If there is a great demand, this medicine should be cheaper pr pill. I said should but that is not always the case.
Medicine are patented for a specific time, but in many cases when this time is up the medicine is discontinued whereas it could greatly benefit e.g. Africa.

My wife works at a hospital pharmacy and at the department making medicine for cancer patients.
Some of the medicine is so specific or has such a narrow "target group" that it costs over 100 000 NoK (~ €12 000) for a single dose. Imagine the stress of the lab technician who handles the jar of powder worth millions and if made wrong when diluting a dose, it needs to be thrown out.
