CVT-301 then Placebo (AB)
Placebo then CVT-301 (BA)
All subjects will receive both CVT-301 and placebo in two dosing periods separated by one day. Subjects will be randomized 1:1 into sequence AB or BA [CVT-301 (A) administered first, followed by placebo (B), or the reverse order (BA)] and they will start pre-treatment of carbidopa (as Lodosyn®) administered every 8 hours until the completion of all study treatments.
