• the neurotoxin l-Methyl-4-phenyl-l,2,3,6-tetrahydropyridine was identified as a compound that selectively induced degeneration of dopaminergic neurons in the substantia nigra when it was discovered as a contaminant in heroin and users presented with clinical symptoms indistinguishable from PD. It is now used in non-human primates to model primary parkinsonian motor symptom phenotypes and subsequent response to therapies such as L-dopa including dyskinesia- thus it can be used as foundational model for LID.

• Compound 1 was administered in a single ascending dose (SAD) study conducted in approximately 54 healthy adult volunteers to investigate Compound 1 pharmacokinetics, safety, and tolerability. The study was conducted in two groups.
• SAD ascending dose
• Group 1 evaluated multiple dose cohorts administered Compound 1 in a single ascending dose (SAD) manner to establish a maximum tolerated dose (MTD) using the doses described in Table 10.
• SAD single ascending dose
• MTD maximum tolerated dose
• MTD was established at the dose which produced mild to moderate cholinergic adverse effects. Cholinergic effects were monitored for each dose, including pupillometry and salivation.

Subjects received 8 mg of fesoterodine fumarate tablet or matched placebo tablet 4 hours prior to administration of 40 mg of Compound 1. [0096] Results: Safety - In Group 1, a total of 95 treatment-emergent adverse events (TEAEs) were observed by 22 (61.6%) of the 36 subjects who received any dose of compound 1. About 50.0%, 33.3%, 50.0%, 50.0%, 50.0%, 83.3%, and 100% subjects in 0 mg (placebo), 1 mg, 3mg, 10 mg, 20 mg, 40 mg, and 60 mg treatment groups, respectively, reported TEAEs.

• the administration of Compound 1 following single oral doses ranging from 1 mg to 40 mg was generally safe and well tolerated in healthy subjects, with 40 mg established as the MTD of Compound 1 when administered alone. Objective increase in salivation was observed with increasing dose of Compound 1.
• pretreatment with extended-release fesoterodine resulted in a delay in TEAE onset following Compound 1 dosing.
