I think we can all agree that the drug is only viable if the human results are equivalent to the macaque results. They could sell it for less and make less money, but how do they justify charging insurance 80k a year for endo, prostate cancer, RA, or pulmonary fibrosis, or whatever other indications they have, while charging cash customers only 20k a year for hair loss?
Our resident statistician tells us that the odds of the macaque results translating to humans is less than 1%. Clearly sophisticated investors think the chance is a great deal higher than that, as those are not odds they would take. Perhaps if they had a Canadian statistician they would make better investments.
