- Primary Outcome Measures
Name Time Method Main Objective: The objective of this study is to investigate the efficacy and safety of two different dose levels of NT 201 (75 U or 100 U per cycle), compared with placebo, in reducing the salivary flow rate, and the severity and frequency of chronic troublesome sialorrhea that occurs as a result of various neurological conditions in adult subjects.;Secondary Objective: not applicable;Primary end point(s): Unstimulated salivary flow rate:Change from baseline to week 4; Subject's GICS entry (rating on the Global Impression of Change Scale; or carer's GICS entry, if the subject is not able to answer): week 4.;Timepoint(s) of evaluation of this end point: 4 weeks after first injection
- Secondary Outcome Measures
Name Time Method Secondary end point(s): Unstimulated salivary flow rate: Change from baseline to weeks 8 and 12. Subject's GICS entry (or carer's GICS entry, if the subject is not able to answer):weeks 1, 2, 8 and 12.;Timepoint(s) of evaluation of this end point: Weeks 1, 2, 8 and 12
