My father has recently been requested to participate in a study of a new drug called Tasmar, aka- Tolcapone. Has anyone else been approached to participate in this study or know anything about this drug? My dad has not responded to any other medications- including Sinemet- maybe that is why they chose him, but the letter indicates differently. I am just looking for anyone else that is considering participating in the study. Please email me at [log in to unmask] or respond on the listserv for eveyones' benifit. Thank you for your time.
