CUVPOSA is indicated to reduce chronic severe drooling in patients aged 3 to 16 years with neurologic conditions associated with problem drooling (e.g., cerebral palsy).

DOSAGE AND ADMINISTRATION

CUVPOSA must be measured and administered with an accurate measuring device [see Patient Counseling Information (17) ].

Initiate dosing at 0.02 mg/kg orally three times daily and titrate in increments of 0.02 mg/kg every 5-7 days based on therapeutic response and adverse reactions. The maximum recommended dosage is 0.1 mg/kg three times daily not to exceed 1.5-3 mg per dose based upon weight. For greater detail, see Table 1.

During the four-week titration period, dosing can be increased with the recommended dose titration schedule while ensuring that the anticholinergic adverse events are tolerable. Prior to each increase in dose, review the tolerability of the current dose level with the patient's caregiver.

CUVPOSA should be dosed at least one hour before or two hours after meals.

The presence of high fat food reduces the oral bioavailability of CUVPOSA if taken shortly after a meal [see Clinical Pharmacology (12.3) ].

CONTRAINDICATIONS

CUVPOSA is contraindicated in:

WARNINGS AND PRECAUTIONS

5.1 Constipation or Intestinal Pseudo-obstruction

Constipation is a common dose-limiting adverse reaction which sometimes leads to glycopyrrolate discontinuation [see Adverse Reactions (6.1) ]. Assess patients for constipation, particularly within 4-5 days of initial dosing or after a dose increase. Intestinal pseudo-obstruction has been reported and may present as abdominal distention, pain, nausea or vomiting.

5.2 Incomplete Mechanical Intestinal Obstruction

Diarrhea may be an early symptom of incomplete mechanical intestinal obstruction, especially in patients with ileostomy or colostomy. If incomplete mechanical intestinal obstruction is suspected, discontinue treatment with CUVPOSA and evaluate for intestinal obstruction.

5.3 High Ambient Temperatures

In the presence of high ambient temperature, heat prostration (fever and heat stroke due to decreased sweating) can occur with the use of anticholinergic drugs such as CUVPOSA. Advise patients/caregivers to avoid exposure of the patient to hot or very warm environmental temperatures.

5.4 Operating Machinery or an Automobile

CUVPOSA may produce drowsiness or blurred vision. As appropriate for a given age, warn the patient not to engage in activities requiring mental alertness such as operating a motor vehicle or other machinery, or performing hazardous work while taking CUVPOSA.

5.5 Anticholinergic Drug Effects

Use CUVPOSA with caution in patients with conditions that are exacerbated by anticholinergic drug effects including:

ADVERSE REACTIONS

The following serious adverse reactions are described elsewhere in the labeling:

The most common adverse reactions reported with CUVPOSA are dry mouth, vomiting, constipation, flushing, and nasal congestion.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data described below reflect exposure to CUVPOSA in 151 subjects, including 20 subjects who participated in an 8-week placebo-controlled study (Study 1) and 137 subjects who participated in a 24-week open-label study (six subjects who received CUVPOSA in the placebo-controlled study and 131 new subjects).

Table 2 presents adverse reactions reported by >= 15% of CUVPOSA-treated subjects for the placebo-controlled clinical trial.

Headache 3 (15%) 1 (6%)
Sinusitis 3 (15%) 1 (6%)
Upper Respiratory Tract Infection 3 (15%) 0
Urinary Retention 3 (15%) 0

The following adverse reactions occurred at a rate of <2% of patients receiving CUVPOSA in the open-label study.

6.2 Postmarketing Experience

The following adverse reactions have been identified during postapproval use of other formulations of glycopyrrolate for other indications. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Additional adverse reactions identified during postapproval use of glycopyrrolate tablets include: loss of taste and suppression of lactation.

DRUG INTERACTIONS

Drugs Affected by Reduced GI Transit Time

Glycopyrrolate reduces GI transit time, which may result in altered release of certain drugs when formulated in delayed- or controlled-release dosage forms.

Amantadine

The anticholinergic effects of glycopyrrolate may be increased with concomitant administration of amantadine. Consider decreasing the dose of glycopyrrolate during coadministration of amantadine.

Drugs Whose Plasma Levels May be Increased by Glycopyrrolate

Coadministration of glycopyrrolate may result in increased levels of certain drugs.

Drugs Whose Plasma Levels May be Decreased by Glycopyrrolate

Coadministration of glycopyrrolate may result in decreased levels of certain drugs.

USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C

There are no adequate and well-controlled studies in pregnant women. Animal reproduction studies have not been conducted with glycopyrrolate. It is also not known whether glycopyrrolate can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. CUVPOSA should be given to a pregnant woman only if clearly needed.

8.3 Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when CUVPOSA is administered to a nursing woman.

8.4 Pediatric Use

CUVPOSA was evaluated for chronic severe drooling in patients aged 3-16 years with neurologic conditions associated with problem drooling. CUVPOSA has not been studied in subjects under the age of 3 years.

8.5 Geriatric Use

Clinical studies of CUVPOSA did not include subjects aged 65 and over.

8.6 Renal Impairment

Because glycopyrrolate is largely renally eliminated, CUVPOSA should be used with caution in patients with renal impairment [see Clinical Pharmacology (12.3) ].

OVERDOSAGE

Because glycopyrrolate is a quaternary amine which does not easily cross the blood-brain barrier, symptoms of glycopyrrolate overdosage are generally more peripheral in nature rather than central compared to other anticholinergic agents. In case of accidental overdose, therapy may include:

DESCRIPTION

CUVPOSA is an anticholinergic drug available as an oral solution containing 1 mg glycopyrrolate per 5 mL. The chemical name for glycopyrrolate is pyrrolidinium, 3-[(cyclopentylhydroxyphenylacetyl) oxy]-1,1-dimethyl-,bromide. The chemical structure is:

The empirical formula for CUVPOSA is C19H28BrNO3 and the molecular weight is 398.33. The inactive ingredients in CUVPOSA are: citric acid, glycerin, natural and artificial cherry flavor, methylparaben, propylene glycol, propylparaben, saccharin sodium, sodium citrate, sorbitol solution, and purified water.

CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Glycopyrrolate is a competitive inhibitor of acetylcholine receptors that are located on certain peripheral tissues, including salivary glands. Glycopyrrolate indirectly reduces the rate of salivation by preventing the stimulation of these receptors.

12.2 Pharmacodynamics

Glycopyrrolate inhibits the action of acetylcholine on salivary glands thereby reducing the extent of salivation.

12.3 Pharmacokinetics

Absorption

In a parallel study of children (n=6 per group) aged 7-14 years undergoing intraocular surgery, subjects received either intravenous (IV) or oral glycopyrrolate as a premedication. The mean absolute bioavailability of oral glycopyrrolate tablets was low (approximately 3%) and highly variable among subjects (range 1.3 to 13.3%). A similar pattern of low and variable relative bioavailability is seen in adults.

Analysis of population pharmacokinetic data from normal adults and children with cerebral palsy associated chronic moderate to severe drooling failed to demonstrate linear pharmacokinetics across the dose range. In the same analysis, population estimates of the apparent oral clearance (scaled by weight in children and adults) ranged from 5.28 - 38.95 L/hr/kg for healthy adults and 8.07 - 25.65 L/hr/kg for patients with cerebral palsy, a reflection of the low and highly variable oral bioavailability of glycopyrrolate.

Absorption of CUVPOSA (fasting) was compared to that of a marketed glycopyrrolate oral tablet. The Cmax after oral solution administration was 23% lower compared to tablet administration and AUC0-inf was 28% lower after oral solution administration. Mean Cmax after oral solution administration in the fasting state was 0.318 ng/mL, and mean AUC0-24 was 1.74 ng.hr/mL. Mean time to maximum plasma concentration for CUVPOSA was 3.1 hours, and mean plasma half-life was 3.0 hours.

In healthy adults, a high fat meal was shown to significantly affect the absorption of glycopyrrolate oral solution (10 mL, 1 mg/5 mL). The mean Cmax under fed high fat meal conditions was approximately 74% lower than the Cmax observed under fasting conditions. Similarly, mean AUC0-T was reduced by about 78% by the high fat meal compared with the fasting AUC0-T. A high fat meal markedly reduces the oral bioavailability of CUVPOSA. Therefore, CUVOPSA should be dosed at least one hour before or two hours after meals. Pharmacokinetic results (mean +- SD) are described in Table 3.

Distribution

After IV administration, glycopyrrolate has a mean volume of distribution in children aged 1 to 14 years of approximately 1.3 to 1.8 L/kg, with a range from 0.7 to 3.9 L/kg. In adults aged 60-75 years, the volume of distribution was lower (0.42 L/kg +/- 0.22).

Metabolism

In adult patients who underwent surgery for cholelithiasis and were given a single IV dose of tritiated glycopyrrolate, approximately 85% of total radioactivity was excreted in urine and <5% was present in T-tube drainage of bile. In both urine and bile, >80% of the radioactivity corresponded to unchanged drug. These data suggest a small proportion of IV glycopyrrolate is excreted as one or more metabolites.

Elimination

Approximately 65-80% of an IV glycopyrrolate dose was eliminated unchanged in urine in adults. In two studies, after IV administration to pediatric patients ages 1-14 years, mean clearance values ranged from 1.01- 1.41 L/kg/hr (range 0.32 -2.22 L/kg/hr). In adults, IV clearance values were 0.54 +- 0.14 L/kg/hr.

Pediatrics

The estimated apparent clearance of glycopyrrolate from a population pharmacokinetic analysis (scaled by weight in children and adults) of oral and IV data was found to be 13.2 L/hr/kg or 92.7 L/hr for a typical 70 kg subject. In the same population based analysis, gender was not identified as having an effect on either glycopyrrolate clearance or systemic exposure.

Gender

Population pharmacokinetic evaluation of adults and children administered IV or oral glycopyrrolate identified no effect of gender on glycopyrrolate clearance or systemic exposure.

Race

The pharmacokinetics of glycopyrrolate by race have not been characterized.

Elderly

Glycopyrrolate pharmacokinetics have not been characterized in the elderly.

Renal Impairment

In one study, glycopyrrolate 4 mcg/kg was administered intravenously in uremic patients undergoing renal transplantation surgery. Mean AUC (10.6 mcg[? ]h/L), mean plasma clearance (0.43 L/hr/kg) and mean 3-hour urinary excretion (0.7%) for glycopyrrolate were significantly different than those of control patients (3.73 ug[? ]h/L, 1.14 L/hr/kg, and 50%, respectively). These results suggest that elimination of glycopyrrolate is severely impaired in patients with renal failure.

Hepatic Impairment

Glycopyrrolate is largely renally eliminated. The pharmacokinetics of glycopyrrolate have not been evaluated in patients with hepatic impairment.

NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term animal studies have not been performed to evaluate the carcinogenic potential of glycopyrrolate.

Glycopyrrolate did not elicit any genotoxic effects in the Ames mutagenicity assay, the human lymphocyte chromosome aberration assay, or the micronucleus assay.

Glycopyrrolate was assessed for effects on fertility or general reproductive function in rats. Rats of both genders received glycopyrrolate at dosages up to 100 mg/kg/day via oral gavage (approximately 50 times the maximum recommended human dose, when comparing on the basis of body surface area estimates). No treatment-related effects on fertility or reproductive parameters of both genders were observed in this study.

CLINICAL STUDIES

CUVPOSA was evaluated in a multi-center, randomized, double-blind, placebo-controlled, parallel, eight-week study for the control of pathologic drooling in children (Study 1). The study enrolled 38 subjects aged 3-23 years; thirty-six subjects were aged 3-16 years and two patients were greater than 16 years. The subjects were male or female, weighed at least 13 kg (27 lbs), and had cerebral palsy, mental retardation, or another neurologic condition associated with problem drooling defined as drooling in the absence of treatment so that clothing became damp on most days (approximately five to seven days per week). Subjects were randomized in a 1:1 fashion to receive CUVPOSA or placebo. Doses of study medication were titrated over a 4-week period to optimal response beginning at 0.02 mg/kg three times a day increasing doses in increments of approximately 0.02 mg/kg three times per day every 5-7 days, not to exceed the lesser of approximately 0.1 mg/kg three times per day or 3 mg three times per day.

Subjects were evaluated on the 9-point modified Teacher's Drooling Scale (mTDS), which is presented below. The mTDS evaluations were recorded by parents/caregivers 3 times daily approximately two hours post-dose on evaluation days during pre-treatment baseline and at Weeks 2, 4, 6 and 8 of therapy.
