Brief Summary

In low-income areas worldwide, most patients with Parkinson's disease (PD) cannot afford long-term Levodopa therapy. A potential therapeutic option for them is the use of a legume called Mucuna Pruriens var. Utilis (MP), which has seeds with a high levodopa content (5-6%) and grows in all tropical areas of the world. MP powder is very cheap (total annual cost for a PD patient: 10-15 US $). The aim of this study is to assess efficacy and tolerability of acute and chronic use of MP compared to standard Levodopa therapy. The primary objective of this study is to investigate efficacy of acute levodopa challenge using MP in comparison to levodopa with a Dopa Decarboxylase Inhibitor (LD+DDCI) and without (LD-DDCI) and placebo. The secondary objectives are to investigate safety of acute intake of MP as well as efficacy and safety of chronic intake of MP over a 8-week period in comparison to usual LD+DDCI home therapy.

Study Arms (3)

MP-Equivalent; MP-Low; MP+DDCI

EXPERIMENTAL

MP-Equivalent: Mucuna pruriens powder at equivalent dosage than LD+DDCI. The dose of MP is calculated to obtain a 5-fold Levodopa dose than LD+DDCI (for example 100mg of Madopar corresponds to 500mg of Levodopa in MP). MP-Low: Mucuna pruriens powder at low dosage. The dose of MP is calculated to obtain a 3.5-fold Levodopa content than LD+DDCI (for example 100mg of Madopar corresponds to 350mg of Levodopa in MP) MP+DDCI: Mucuna pruriens powder plus Benserazide. The dosage of MP is calculated to obtain the same Levodopa content than LD+DDCI (for example 100mg of Madopar corresponds to 100mg of Levodopa in MP plus 25mg of Benserazide)

ACTIVE COMPARATOR

LD+DDCI: Levodopa plus Benserazide (dispersible formulation). The dose is calculated as 3.5mg per kg of body weight. LD-DDCI: Levodopa without any dopa decarboxylase inhibitor (galenic formulation). The dose is 5-fold than LD+DDCI.
