The purpose of this study is to assess the safety and tolerability of three doses of LP-10 (intravesical tacrolimus). Twelve subjects meeting the inclusion and exclusion criteria will be enrolled and treated in a prospective and multi-center trial with LP-10. The proposed trial will recruit 12 subjects in a dose-escalation trial where 4 subjects will be allocated into each one of three groups.
