Proportion of Responders According to the Modified Teacher's Drooling Scale (mTDS) [ Time Frame: 6 months ] [ Designated as safety issue: No ]
The primary efficacy variable was patient's response status using the change from baseline to Week 24 evaluations of the mTDS assessment. Each patient was classified as a responder or non-responder according to the change in their mean mTDS rating from baseline to Week 24. Responders were patients who had at least a 3-point decrease in mTDS rating from baseline

  • Parent/Caregiver's Assessment of the Extent of Drooling Using Visual Analog Scale (VAS) [ Time Frame: Baseline ] [ Designated as safety issue: No ]
    Parents/caregivers were to complete a 10 cm "Parent/Caregiver's Assessment of Extent of Drooling for the Day" VAS assessment (0 = normal; 10 = extremely wet) to provide an overall assessment of the extent of drooling for that day.
  • Parent/Caregiver's Assessment of the Extent of Drooling Using VAS [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
    Parents/caregivers were to complete a 10 cm "Parent/Caregiver's Assessment of Extent of Drooling for the Day" VAS assessment (0 = normal; 10 = extremely wet) to provide an overall assessment of the extent of drooling for that day.
  • Parent/Caregiver's Global Assessment of Treatment [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
    The parent/caregiver performed an overall evaluation of glycopyrrolate liquid for the treatment of drooling, benefits, and side effects over the duration of the study. The parent/caregiver selected one of the following choices to assess if 'This is a worthwhile treatment': 1 = strongly agree, 2 = agree, 3 = neutral, 4 = disagree, 5 = strongly disagree. A dichotomous global assessment was also performed and summarized with the categories 'responder' (strongly agree and agree responses aggregated) and 'non-responder'(neutral, disagree, and strongly disagree responses aggregated)
  • Investigator's Global Assessment of Treatment [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
    The investigator performed an overall evaluation of glycopyrrolate liquid for the treatment of drooling, benefits, and side effects over the duration of the study. The investigator selected one of the following choices to assess if 'This is a worthwhile treatment': 1 = strongly agree, 2 = agree, 3 = neutral, 4 = disagree, 5 = strongly disagree. A dichotomous global assessment was also performed and summarized with the categories 'responder' (strongly agree and agree responses aggregated) and 'non-responder' (neutral, disagree, and strongly disagree responses aggregated)

Safety and Efficacy Study of Oral Glycopyrrolate Liquid for the Treatment of Pathologic (Chronic Moderate to Severe) Drooling in Pediatric Patients 3 to 18 Years of Age With Cerebral Palsy or Other Neurologic Conditions
A Six-Month, Multi-Center, Open-Label Study to Assess the Safety and Efficacy of Oral Glycopyrrolate Liquid for the Treatment of Pathologic (Chronic Moderate to Severe) Drooling in Pediatric Patients 3 to 18 Years of Age With Cerebral Palsy or Other Neurologic Conditions

This is an open-label clinical research study of an oral glycopyrrolate liquid for the treatment of chronic moderate to severe drooling in patients with cerebral palsy or other neurological conditions. Patients participating in the study will receive oral glycopyrrolate liquid (1 mg/5 ml) three times a day (TID) for study duration of 24 weeks. After a washout, screening, and 2-day baseline period, patients will be enrolled in a 4-week dose titration period. Glycopyrrolate liquid doses will be titrated using dose levels in the Dose Titration Schedule. Titration will begin at 0.02 mg/kg per dose TID and sequentially increased in 0.02 mg/kg per dose increments TID every 5-7 days during the first four weeks until optimal individualized response is obtained for each patient or a maximum dose of 0.1 mg/kg TID is reached, not exceeding 3 mg TID or Dose-level 5 in the Dose Titration Schedule, whichever is lesser. Optimal dose for each patient is the dose at which he/she is receiving the maximum benefit from the study drug (greatest improvement in drooling) while experiencing minimum side effects. All patients will receive close attention by study staff throughout the study.

Inclusion Criteria:

To be included in this study, patients must meet the following criteria:

  • Male or female, weighing at least 13 kilograms (27 pounds), aged 3 through 18 years
  • Diagnosis of cerebral palsy and/or mental retardation or any other neurologic impairment or condition (cognitively capable and cognitively impaired patients may be enrolled)
  • Chronic drooling in the absence of treatment to the extent that the chin or clothing becomes wet on most days by confirming the Modified Teacher's Drooling Scale score ≥ 5
  • Must be living in a situation where reliable parents/caregivers are willing and capable of administering medications, as determined by the investigator
  • Written informed consent signed by the parent or legally acceptable representative
  • Written assent signed by the age-appropriate patient if mentally capable, as determined by the investigator, and required by the site's Institutional Review Board
  • If female of childbearing potential, the patient must have a negative pregnancy test at screening and Visit 2
  • If female of childbearing potential and sexually active, she must use a medically acceptable form of contraception

Exclusion Criteria:

Patients are excluded from this study if they meet any of the following criteria:

  • Patients who used glycopyrrolate within approximately 24 hours prior to the start of the baseline period, which began on Day -2
