Glycopyrrolate

Larry Dillaha, M.D.Executive Vice President

for the treatment of chronic moderate-severe drooling in pediatric patients

Cerebral Palsy (CP) Cerebral Palsy (CP) Definition:

A group of motor impairments manifested as various physical and mental disorders caused by injury to the brain.

Common symptoms:Uncontrolled reflex movementsSpasticity affecting different parts of the bodyMental retardationSeizure disordersVision impairmentsAuditory impairmentsDrooling

Impact of CPImpact of CP

800,000 patients in US

$920,0001 total lifetime cost of care

Patients need around-the-clock care

Frequent doctor and hospital visits

Shortened life expectancy

DroolingDroolingDefinition - unintentional loss of saliva from the mouth

Sialorrhea - increase in salivary flow

Anatomy - 3 pairs of major salivary glandsParotid Submandibular – 70%Sublingual

Oral PhaseInability to close the mouthPoor head controlAbnormal tongue controlReduced intra-oral sensation

Pediatric DroolingPediatric Drooling

Drooling is normal in growing children, up to the age of 18 months

Drooling beyond the age of 4 is considered abnormal

Drooling frequently persists in children with CP

Parents of more than 1400 patients with CP stated:– Drooling is sometimes a problem 'requiring a bib' (34%)

– Drooling is often a problem 'requiring daily clothing changes' (16%)1

Complications of Severe DroolingComplications of Severe Drooling

Chronically irritated, chapped, or macerated skin cheilitis 67%

Pooling of saliva in mouthLeaking of saliva into the hypopharynx– Congested breathing– Loud rattle in the throat

Unrecognized aspirationRecurrent silent pneumoniaAnxiety and refusal to swallow

Efficacy AssessmentsEfficacy AssessmentsEfficacy will be assessed by:

Modified Teacher’s Drooling Scale (mTDS)

Visual analog scale (VAS) performed at the end of the day on thesame days as the mTDS

Rate today’s overall extent of drooling by placing a mark on the line below:

Normal Extremely wet

Global assessment by parent/caregiver and Investigator
