Is there a potential demand or requirement for a stem cell clinical trial for raised PSA?

Dear friends, my company develops and manufacture safe, effective yet cost affordable stem cell products for doctors to clinical trial/treat their patients.
While running a heart clinical trial, we noticed an 87-year-old patient with PSA 26 and free PSA of 6.0 returned to normal incidentally; so, may I ask for your personal opinion/comments what’s the likely hood one with raised PSA will ask for such treatment trial? Given the consideration that the treatment cost might become as high as 25k in the future? Thanks.
