Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To explore the safety, tolerability, pharmacokinetics and efficacy of ABT-SLV187 in advanced Parkinson's disease (PD) patients with severe motor complications. The complications of medical devices for the naso-jejunum (NJ) infusion system of ABT-SLV187 will also be investigated.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Levodopa-carbidopa intestinal gel

Following a 28-day Run-in Period where participants are switched from prior anti-PD medications to monotherapy with an oral 100 mg levodopa/10 mg carbidopa tablet (optimized every 3rd hour during waking hours), participants receive ABT-SLV187 (levodopa-carbidopa intestinal gel), administered over 16 hours a day with an infusion pump directly into the proximal jejunum by an NJ tube, for 3 weeks.

The individually-adjusted infusion dose (composed of the morning dose, the continuous maintenance dose, and the extra dose) is optimized by the Investigator for each participant during the study based on the participant's symptoms.
