Study Data Show CUVPOSA® Reduced Chronic Severe Drooling in Patients Ages 3-16 Years-Old with Neurologic Conditions

FLORHAM PARK, N.J., Jan. 25, 2012 /PRNewswire/ -- Shionogi Inc., the U.S.-based group company of Shionogi & Co., Ltd., today announced results from two studies published online today in the journal Therapeutics and Clinical Risk Management: the first study, a randomized, double-blind, placebo-controlled phase III trial, showed that children ages 3-16 with problem drooling due to neurologic conditions demonstrated a significantly better response to CUVPOSA® (glycopyrrolate) oral solution than to placebo.(1) The second study, a multicenter, open-label trial, evaluated the safety and efficacy of CUVPOSA® for over 24 weeks.(2)  The majority of patients in this study were between the ages of 3-16 with moderate-to-severe drooling.  CUVPOSA® oral solution is the first and only U.S. Food and Drug Administration-approved treatment to reduce chronic severe drooling in patients ages 3-16 with neurologic conditions associated with problem drooling, such as cerebral palsy.  

"Chronic severe drooling is a health issue for children with neurologic disorders," said lead study investigator Robert S. Zeller, MD, director, Blue Bird Circle Clinic for Pediatric Neurology at Texas Children's Hospital, Houston, Texas. "These studies reinforce the efficacy and safety, respectively, of CUVPOSA®." 

After eight weeks in the first study of 38 patients [CUVPOSA® (n=20), placebo (n=18)], 14 of 19 patients (73.7 percent) in the CUVPOSA® group and three of 17 (17.6 percent) in the placebo group exhibited at least a 3-point improvement on the modified Teacher's Drooling Scale (mTDS) (P=0.0011).  Two of the 38 patients were older than 16 and, as such, were excluded from the results.  A beneficial effect of CUVPOSA® was observed as early as two weeks after treatment initiation (52.6 percent; P=0.0007), with the proportion of responders increasing continuously through week 8.  Mean improvements in mTDS score at week 8 were 3.94 points (SD: 1.95; 95 percent CI 2.97, 4.91; median: 4.30 points) in the CUVPOSA® group and 0.71 points (SD: 2.14; 95 percent CI -0.43, 1.84; median: 0.25 points) in the placebo group (P<0.0001).

Statistically significant differences in the first study were observed for both the investigator and parent/caregiver global assessments of study medication.  For patients in the CUVPOSA® group, 84.2 percent of investigators and 100 percent of parent/caregivers agreed that the treatment was worthwhile, compared with 41.2 percent of investigators (P=0.0140) and 56.3 percent of parent/caregivers (P=0.0017) of patients in the placebo group.

"Parents and caregivers of children with neurologic conditions, such as cerebral palsy, can face many challenges," said Jennifer Davidson, DO, medical director, Shionogi Inc. "By treating the severe drooling that is often associated with these conditions, these caregivers can focus their time and resources on other aspects of their children's care. With CUVPOSA®, we are continuing our commitment to help address the unmet medical needs of patients." 

All 20 patients treated with CUVPOSA® and 15 of 18 (83.3 percent) who received the placebo had at least one treatment-emergent adverse event (TEAE), including 15 (75 percent) and seven (39 percent), respectively, who had TEAEs considered by the investigator to be related to treatment.  Four patients (20 percent) in the CUVPOSA® group, but none in the placebo group, had at least one severe TEAE.  The most common adverse reactions (greater than 30 percent incidence) were dry mouth, constipation, vomiting and nasal congestion.  Adverse reactions also included flushing (25 percent) and urinary retention (15 percent).

The second study of 137 intent-to-treat patients was a multicenter, open-label trial evaluating the safety and efficacy of CUVPOSA®. Most patients (n=122; 89 percent) had at least one TEAE, 47 percent of which were deemed related to CUVPOSA®, with most being mild to moderate in intensity.  Several TEAEs occurred more frequently in the high (>0.2 mg/kg) and middle (greater than or equal to 0.1 to less than or equal to 0.2 mg/kg) than in the low dose (<0.1 mg/kg) group.  Fourteen patients had 20 serious AEs, eight while taking the study drug and six within 30 days of the last dose.  Of these 20 SAEs, four were considered treatment-related: nystagmus, esophageal candidiasis, dehydration and gastrointestinal motility disorder. The most common treatment-emergent adverse events (incidence >5%) are constipation, vomiting, diarrhea, pyrexia, dry mouth, flushing and nasal congestion. Nineteen patients (13.9%) discontinued due to an AE, but no AE trend was specifically associated with discontinuation. 

After 24 weeks, 52.3 percent (95 percent CI, 43.7 percent–60.9 percent) of patients had a greater than or equal to 3-point decrease in mTDS from baseline and were classified as responders to treatment with CUVPOSA®.  The percentage of the 53 non-naive patients (i.e., patients previously treated with CUVPOSA®) classified as responders (58.5 percent; 95 percent CI, 45.2 percent–71.8 percent) was higher than that of the 84 naive patients (48.1 percent; 95 percent CI, 36.9 percent–59.2 percent).  At the end of the study, 83.5 percent of parents/caregivers and 85.8 percent of investigators rated CUVPOSA® as a worthwhile treatment.   

CUVPOSA® is supplied as a cherry-flavored, liquid solution for oral administration and was FDA approved in the United States in July 2010 and launched commercially in April 2011. 


CUVPOSA® is an anticholinergic indicated to reduce chronic severe drooling in patients ages 3-16 with neurologic conditions associated with problem drooling (e.g., CP). CUVPOSA® indirectly reduces the rate of salivation by preventing stimulation of acetylcholine receptors that are located on certain peripheral tissues, such as salivary glands.  CUVPOSA® is dosed on a titration schedule based on weight, therapeutic response and adverse reactions.  It must be administered to patients by caregivers using an accurate measuring device.  Please see the full prescribing information at for administration and dosing instructions. 

Important Safety Information About CUVPOSA®

  • Contraindicated in conditions that preclude anticholinergic therapy (e.g., glaucoma, paralytic ileus, unstable cardiovascular status in acute hemorrhage, severe ulcerative colitis, toxic megacolon complicating ulcerative colitis, myasthenia gravis)
  • Contraindicated in patients taking solid oral dosage forms of potassium chloride. The passage of potassium chloride tablets through the GI tract may be arrested or delayed with coadministration of Cuvposa
  • Constipation is a common dose-limiting adverse reaction and may lead to discontinuation of Cuvposa. Assess patients for constipation, particularly within 4-5 days of initial dosing or after a dose increase. Intestinal pseudoobstruction may present as abdominal distention, pain, nausea, or vomiting
  • Incomplete mechanical intestinal obstruction: diarrhea may be an early symptom, especially in patients with ileostomy or colostomy. If obstruction is suspected, discontinue Cuvposa and evaluate
  • Avoid patient exposure to high ambient temperatures. Heat prostration (fever and heatstroke due to decreased sweating) can occur with use of anticholinergic drugs such as Cuvposa
  • Cuvposa may cause drowsiness or blurred vision; do not engage in age-appropriate activities requiring mental alertness such as operating a motor vehicle or other machinery or performing hazardous work while taking Cuvposa
  • Use Cuvposa with caution in patients with conditions that are exacerbated by anticholinergic drug effects including:
    • Autonomic neuropathy, renal disease, ulcerative colitis—large doses may suppress intestinal motility to the point of producing a paralytic ileus and for this reason may precipitate or aggravate "toxic megacolon," a serious complication of the disease; hyperthyroidism, coronary heart disease, congestive heart failure, cardiac tachyarrhythmias, tachycardia, and hypertension; hiatal hernia associated with reflux esophagitis
  • Glycopyrrolate reduces GI transit time which may result in altered release of certain drugs when formulated in delayed or controlled-release forms. Cuvposa can increase serum levels of atenolol, metformin and digoxin (slow dissolution tablets; consider other oral dosage forms of digoxin). Dose reductions of atenolol or metformin may be needed
  • Cuvposa may decrease serum levels of haloperidol or levodopa. Consider dose increase of levodopa and closely monitor haloperidol patients for worsening of schizophrenic symptoms and development of tardive dyskinesia when coadministered with Cuvposa
  • The anticholinergic effects of Cuvposa may be increased with concomitant administration of amantadine. Cuvposa dose reduction should be considered
  • Cuvposa is largely renally eliminated. Cuvposa should be used with caution in patients with renal impairment
  • The most common adverse reactions (incidence greater than or equal to 30%) are dry mouth (40%), vomiting (40%), constipation (35%), flushing (30%), and nasal congestion (30%)

About Cerebral Palsy

Cerebral palsy is a lifelong condition that encompasses a group of non-progressive, neurological disorders affecting body movement and muscle coordination.  About 10-30 percent of children with cerebral palsy suffer from excessive drooling.(1)

About Chronic Severe Drooling

Sialorrhea (drooling or excessive salivation) is an unintentional loss of saliva from the mouth.(1)  Drooling is normal in infants, but a significant proportion of the developmentally disabled population experiences drooling caused primarily by neuromuscular dysfunction that makes it hard to swallow.
