- Unstimulated Salivary Flow Rate (USFR) at Week 4 Post-injection Visit (Part A) [ Time Frame: 4 Weeks ]Change weight of expectorated saliva at a Week 4 post-injection visit.
- Clinical Global Impression Change (CGI-C) at Week 4 Post-injection (Part A) [ Time Frame: 4 weeks ]CGI-C was assessed on a 7-point scale ranging from "very much improved" to "very much worse" with 1 assigned to "very much improved" and 7 assigned to "very much worse"; ranging from a minimum score of 1 and a maximum score of 7.
