NPSP
Not really Dew, I think Preos is definetely a superior product than Forteo and it is a near term driver. I am not sure if NPSP will be there by the time it's competition matures. Also osteoporosis is underdiagnosed and because of many babyboomers retiring, Preos will do fine as osteoporosis is a huge market. Reg advertising about PTH, doctors are already aware because of the big pharma. Also Teduglutide proof of concept is a near term driver as I said.
Long term, next gen pth calcilytics is in phase 1, But you might not be holding it till then...:-) Praveen
