Summary
This research study is being done to determine whether treatment with L- Dihydroxyphenylserine (L-DOPS) versus placebo (an inactive substance that looks like study drug) in addition to other Parkinson Disease (PD) drugs will improve balance, walking, and reduce risk of falls and/or severity of falls in PD subjects. The study is also being done to determine the effectiveness, safety, and tolerability of L-DOPS, and whether it will decrease Freezing of Gait (FOG), improve apathy (generalized disinterest) or show a relationship between apathy and slowed movement and fall risk.

Placebo Group
Group I: L-DOPSActive Control1 Intervention
All participants will be on levodopa/carbidopa, and may be on additional dopaminergic drugs including dopamine agonists and/or monoamine type B oxidase inhibitors or amantadine. L-dihydoxyphenylserine will be added, administered as an oral capsule 3 times a day for 4 months. Dosing will begin at 100 mg of L-DOPS three times per day and titrated upward, by 100 mg three times a day, as tolerated. Tolerability will be evaluated based upon questionnaires, patient interviews, vital signs and investigator examination. In order to participate in the study, all subjects must be able to tolerate a minimum tolerated dose of 400 mg three times per day (1200mg/day). Subject maximum dose will be 600 mg three times per day (1800mg/day). Patients will be maintained on this dose for 4 months (until the cross-over). After a 7-day washout, participants will cross over to the Placebo arm.
Group II: PlaceboPlacebo Group1 Intervention

Placebo will be added, administered as an oral capsule 3 times a day for 4 months. Dosing will begin at 100 mg of placebo three times per day and titrated upward, by 100 mg three times a day, as tolerated. Tolerability will be evaluated based upon questionnaires, patient interviews, vital signs and investigator examination. In order to participate in the study, all subjects must be able to tolerate a minimum tolerated dose of 400 mg three times per day (1200mg/day). Subject maximum dose will be 600 mg three times per day (1800mg/day). Patients will be maintained on this dose for 4 months (until the cross-over) After a 7-day washout, participants will cross over to the L-DOPS arm.
