ListOutcomeTime frameDescription
PrimaryOccurrence, Seriousness, Severity, and Causality Assessment of Treatment Emergent Adverse Events (TEAE)Visits at Weeks 4 and 13 combined for each TS; including Visit at Week 8 for TS1TEAEs Related to Study Medication include TEAEs classified as Possibly, Probably and Definitely Related. Treatment Session (TS)
PrimaryOccurrence of Adverse Events of Special Interest (AESI)Visits at Weeks 4 and 13 combined for each TS; including Visit at Week 8 for TS1Treatment Session (TS) AESI includes: Aspiration, Aspirational pneumonia, Choking and Dysphagia.
PrimaryColumbia Suicide Rating Scale (C-SSRS): Suicidal Ideation, Behavior Scores and Intensity ScoresBaseline (Day 1) of each TS to the following: TS1 Visits at Weeks 4, 8, 13; TS2-4 Visits at Weeks 4, 13
Participants Analyzed does not match the Participant Flow because one participant discontinued prior to the first post-injection visit. Per protocol participants were only required to complete two treatment sessions with a maximum of 4 treatment sessions allowed. All subjects received 3500 U doses except for 13 subjects who had decreased doses at Treatment Session 2 and/or 3 (2500 U to 3000 U).
PrimaryOccurrence of Dental Adverse EventsVisits at Weeks 4 and 13 combined for each TS; including Visit at Week 8 for TS1Treatment Session (TS)
SecondaryChange From Baseline in Unstimulated Salivary Flow Rate (USFR): Treatment Sessions 1-4Baseline (Day 1) of each TS to the following: TS1 Visits at Weeks 4, 8, 13; TS2-4 Visits at Weeks 4, 13
For Treatment Sessions 2-4, the change from baseline is calculated using the Week 13 value from the previous Treatment Session as the new baseline. Week 8 was only assessed in Treatment Session 1. Treatment Session (TS) Participants Analyzed does not match the Participant Flow because patient data was not always captured for each endpoint at every visit.
SecondaryChange From Baseline in Clinical Global Impression of Severity (CGI-S)Baseline (Day 1) of each TS to the following: TS1 Visits at Weeks 4, 8, 13; TS2-4 Visits at Weeks 4, 13
CGI-S will be used to record the severity of illness (sialorrhea) on a 7-point scale ranging from a score of 1, "normal" to a score of 7, "among the most extremely ill patients". Treatment Session (TS) Participants Analyzed does not match the Participant Flow because participant discontinued prior to the first post-injection visit.
SecondaryClinical Global Impression of Change (CGI-C)TS1 Visits at Weeks 4, 8, 13; TS2-4 Visits at Weeks 4, 13
CGI-C will be used to record change or improvement of illness (sialorrhea) on a 7-point scale ranging from a score of 1, "very much improved" to a score of 7, "very much worse". Participants Analyzed does not match the Participant Flow because participant discontinued prior to the first post-injection visit. Treatment Session (TS)
SecondaryChange From Baseline in Drooling Frequency and Severity Scale Performed by Trained Assessor (DFSS-I)Baseline (Day 1) of each TS to the following: TS1 Visits at Weeks 4, 8, 13; TS2-4 Visits at Weeks 4, 13
The DFSS will be used to assess the frequency and severity of drooling on a 5-point scale ranging from a score of 1, dry never drools to a score of 5, profuse clothing hands tray objects become wet. Drooling frequency will be assessed on a 4-point scale ranging from a score of 1, never drools to a score of 4, constantly drools. Treatment Session (TS) Participants Analyzed does not match the Participant Flow because participant discontinued prior to the first post-injection visit. The severity score and frequency score are summed together to create the DFSS total score (range 2-9). A decrease from baseline indicates improvement.
SecondaryChange From Baseline in Drooling Frequency and Severity Scale Performed by Subject (DFSS-S)Baseline (Day 1) of each TS to the following: TS1 Visits at Weeks 4, 8, 13; TS2-4 Visits at Weeks 4, 13
The DFSS will be used to assess the frequency and severity of drooling on a 5-point scale ranging from a score of 1, dry never drools to a score of 5, profuse clothing hands tray objects become wet. Drooling frequency will be assessed on a 4-point scale ranging from a score of 1, never drools to a score of 4, constantly drools. Treatment Session (TS) Participants Analyzed does not match the Participant Flow because patient data was not always captured for each endpoint at every visit. The severity score and frequency score are summed together to create the DFSS total score (range 2 -9). A decrease from baseline indicates improvement.
SecondaryChange From Baseline in Patient Global Impression of Severity (PGI-S)Baseline (Day 1) of each TS to the following: TS1 Visits at Weeks 4, 8, 13; TS2-4 Visits at Weeks 4, 13
The PGI-S scale will be used by the subject to rate the severity of his/her illness (sialorrhea) on an 7-point scale ranging from a score of 1, "normal" to a score of 7, "among the most extremely ill". Treatment Session (TS) Participants Analyzed does not match the Participant Flow because participant discontinued prior to the first post-injection visit.
SecondaryPatient Global Impression of Change (PGI-C)TS1 Visits at Weeks 4, 8, 13; TS2-4 Visits at Weeks 4, 13
The PGI-C scale will be used by the subject to rate the change in symptoms of his/her illness (sialorrhea) on an 7-point scale ranging from a score of 1, "very much improved" to a score of 7, "very much worse". Treatment Session (TS) Participants Analyzed does not match the Participant Flow because participant discontinued prior to the first post-injection visit.
SecondaryChange From Baseline in Drooling Impact Score (DIS)Baseline (Day 1) of each TS to the following: TS1 Visits at Weeks 4, 8, 13; TS2-4 Visits at Weeks 4, 13
The DIS is a 10-item questionnaire with each item rated by the subject to evaluate the impact of sialorrhea on daily activities (e.g., speech, social activities). Treatment Session (TS) Participants Analyzed does not match the Participant Flow because patient data was not always captured for each endpoint at every visit. Subject is requested to compare their current status to their last study visit using a 4-point scale ranging from a score of 1, not at all to a score of 4, very much. The DIS total score ranges from 10 to 40. A negative change from baseline indicates a positive clinical outcome.
