Duopa Prescribing Information

2.1 DUOPA Daily Dose

DUOPA is administered over a 16-hour infusion period. The daily dose is determined by individualized patient titration and composed of:

A Morning Dose
A Continuous Dose
Extra Doses

The maximum recommended daily dose of DUOPA is 2000 mg of the levodopa component (i.e., one cassette per day) administered over 16 hours. At the end of the daily 16-hour infusion, patients will disconnect the pump from the PEG-J and take their night-time dose of oral immediate-release carbidopa-levodopa tablets.

Treatment with DUOPA is initiated in 3 steps [see Dosage and Administration ( 2.2)]:

Conversion of patients to oral immediate-release carbidopa-levodopa tablets in preparation for DUOPA treatment.
Calculation and administration of the DUOPA starting dose (Morning Dose and Continuous Dose) for Day 1.
Titration of the dose as needed based on individual clinical response and tolerability.

Extra Doses

DUOPA has an extra dose function that can be used to manage acute “Off” symptoms that are not controlled by the Morning Dose and the Continuous Dose administered over 16 hours. The extra dose function should be set at 1 mL (20 mg of levodopa) when starting DUOPA. If the amount of the extra dose needs to be adjusted, it is typically done in 0.2 mL increments. The extra dose frequency should be limited to one extra dose every 2 hours. Administration of frequent extra doses may cause or worsen dyskinesias.

Once no further adjustments are required to the DUOPA Morning Dose, Continuous Dose, or Extra Dose, this dosing regimen should be administered daily. Over time, additional changes may be necessary based on the patient’s clinical response and tolerability.

2.2 Initiation and Titration Instructions

Prepare for DUOPA Treatment

Prior to initiating DUOPA, convert patients from all other forms of levodopa to oral immediate-release carbidopa-levodopa tablets (1:4 ratio). Patients should remain on a stable dose of their concomitant medications taken for the treatment of Parkinson's disease before initiation of DUOPA infusion.

Healthcare providers should ensure patients take their oral Parkinson's disease medications the morning of the PEG-J procedure.

Determine the DUOPA Starting Dose for Day 1

The steps for determining the initial DUOPA daily dosing (Morning Dose and Continuous Dose) for Day 1 are outlined below.

Step 1: Calculate and administer the DUOPA Morning Dose for Day 1
a.	Determine the total amount of levodopa (in milligrams) in the first dose of oral immediate-release carbidopa-levodopa that was taken by the patient on the previous day.
b.	Convert the oral levodopa dose from milligrams to milliliters by multiplying the oral dose by 0.8 and dividing by 20 mg/mL. This calculation will provide the Morning Dose of DUOPA in milliliters.
c.	Add 3 milliliters to the Morning Dose to fill (prime) the intestinal tube to obtain the Total Morning Dose.
d.	The Total Morning Dose is usually administered over 10 to 30 minutes.
e.	Program the pump to deliver the Total Morning Dose.
Step 2: Calculate and administer the DUOPA Continuous Dose for Day 1
a.	Determine the amount of oral immediate-release levodopa that the patient received from oral immediate-release carbidopa-levodopa doses throughout the previous day (16 waking hours), in milligrams. Do not include the doses of oral immediate-release carbidopa-levodopa taken at night when calculating the levodopa amount.
b.	Subtract the first oral levodopa dose in milligrams taken by the patient on the previous day (determined in Step 1 (a)) from the total oral levodopa dose in milligrams taken over 16 waking hours (determined in Step 2 (a)). Divide the result by 20 mg/mL. This is the dose of DUOPA administered as a Continuous Dose (in mL) over 16 hours.
c.	The hourly infusion rate (mL per hour) is obtained by dividing the Continuous Dose by 16 (hours). This value will be programmed into the pump as the continuous rate.
d.	If persistent or numerous “Off” periods occur during the 16-hour infusion, consider increasing the Continuous Dose or using the Extra Dose function. If dyskinesia or DUOPA-related adverse reactions occur, consider decreasing the Continuous Dose or stopping the infusion until the adverse reactions subside.

DUOPA Titration

The daily dose of DUOPA can be titrated as needed, based on the patient’s individual clinical response and tolerability after Day 1 of DUOPA treatment and until a stable daily dose is maintained. Adjustments to concomitant Parkinson’s disease medications may be needed. In the controlled trial, the average number of titration days required to establish a stable Morning and Continuous Dose was 5 days. Additional dose adjustments may be necessary over time based on the patient level of activity and disease progression.

The recommendations for adjusting the DUOPA Morning and Continuous Doses are provided below.

Morning Dose Adjustment

If there was an inadequate clinical response within 1 hour of the Morning Dose on the preceding day, adjust the Morning Dose (excluding the 3 mL to fill the tube) as follows:

If the Morning Dose on the preceding day was less than or equal to 6 mL, increase the Morning Dose by 1 mL.
If the Morning Dose on the preceding day was greater than 6 mL, increase the Morning Dose by 2 mL.

If the patient experienced dyskinesias or DUOPA-related adverse reactions within 1 hour of the Morning Dose on the preceding day, decrease the Morning Dose by 1 mL.

Continuous Dose Adjustment

Consider increasing the Continuous Dose based on the number and volume of Extra Doses of DUOPA (i.e., total amount of levodopa component) that were needed for the previous day and the patient’s clinical response.

Consider decreasing the Continuous Dose if the patient experienced troublesome dyskinesia, or other troublesome DUOPA-related adverse reactions on the preceding day:

For troublesome adverse reactions lasting for a period of one hour or more, decrease the Continuous Dose by 0.3 mL per hour.
For troublesome adverse reactions lasting for two or more periods of one hour or more, decrease the Continuous Dose by 0.6 mL per hour.

2.3 Administration Information

DUOPA should be used at room temperature. Take one DUOPA cassette out of the refrigerator and out of the carton 20 minutes prior to use; failure to use the product at room temperature may result in the patient not receiving the right amount of medication.
DUOPA is delivered as a 16-hour infusion through either a naso-jejunal tube for short-term administration or through a PEG-J for long-term administration.
The cassettes are for single-use only and should not be used for longer than 16 hours, even if some drug product remains.
An opened cassette should not be re-used.
The PEG-J should be disconnected from the pump at the end of the daily 16-hour administration period and flushed with room temperature potable water with a syringe.

Long-term administration of DUOPA requires placement of a PEG-J outer transabdominal tube and inner jejunal tube by percutaneous endoscopic gastrostomy. DUOPA is dispensed from medication cassette reservoirs that are specifically designed to be connected to the CADD®-Legacy 1400 pump.

Establishment of the transabdominal port should be performed by a gastroenterologist or other healthcare provider experienced in this procedure. See Table 1 for the recommended tubing sets for PEG-J administration.

For short-term, temporary administration of DUOPA prior to PEG-J tube placement, treatment may be initiated by a naso-jejunal tube with observation of the patient’s clinical response. See Table 2 for the recommended tubing sets for naso-jejunal administration.

2.4 Discontinuation of DUOPA

Avoid sudden discontinuation or rapid dose reduction in patients taking DUOPA.

If patients need to discontinue DUOPA, the dose should be tapered or patients should be switched to oral immediate-release carbidopa-levodopa tablets [see Warnings and Precautions ( 5.7)].

When using a PEG-J tube, DUOPA can be discontinued by withdrawing the tube and letting the stoma heal. The removal of the tube should only be performed by a qualified healthcare provider.

8.1 Pregnancy

Risk Summary

There are no adequate data on the developmental risk associated with the use of DUOPA in pregnant women. In animal studies, carbidopa-levodopa has been shown to be developmentally toxic (including teratogenic effects) at clinically relevant doses (see Data).

The estimated background risk of major birth defects and miscarriage in the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

When administered to pregnant rabbits throughout organogenesis, carbidopa-levodopa caused both visceral and skeletal malformations in fetuses at all doses and ratios of carbidopa-levodopa tested. No teratogenic effects were observed when carbidopa-levodopa was administered to pregnant mice throughout organogenesis. There was a decrease in the number of live pups delivered by rats receiving carbidopa-levodopa during organogenesis.

8.2 Lactation

Risk Summary

Levodopa has been detected in human milk after administration of carbidopa-levodopa. There are no data on the presence of carbidopa in human milk, the effects of levodopa or carbidopa on the breastfed infant, or the effects on milk production. However, inhibition of lactation may occur because levodopa decreases secretion of prolactin in humans. Carbidopa is excreted in rat milk.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for DUOPA and any potential adverse effects on the breastfed infant from DUOPA or from the underlying maternal condition.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

8.5 Geriatric Use

In the controlled clinical trial, 49% of patients were 65 years and older, and 8% were 75 years and older. In patients 65 years and older, there was an increased risk for elevation of BUN and CPK (above the upper limit of the normal reference range for these laboratory analytes) during treatment with DUOPA compared to the risk for patients less than 65 years.

5.1 Gastrointestinal and Gastrointestinal Procedure-Related Risks

Because DUOPA is administered using a PEG-J or naso-jejunal tube, gastrointestinal complications can occur.

These complications include abscess, bezoar, ileus, implant site erosion/ulcer, intestinal hemorrhage, intestinal ischemia, intestinal obstruction, intestinal perforation, intussusception, pancreatitis, peritonitis, pneumonia (including aspiration pneumonia), pneumoperitoneum, post-operative wound infection, and sepsis. These complications may result in serious outcomes, such as the need for surgery or death.

Instruct patients to notify their healthcare provider immediately if they experience abdominal pain, prolonged constipation, nausea, vomiting, fever, or melanotic stool [see Patient Counseling Information ( 17)].

5.2 Falling Asleep During Activities of Daily Living and Somnolence

Patients treated with levodopa, a component of DUOPA, have reported falling asleep while engaged in activities of daily living, including the operation of motor vehicles, which sometimes resulted in accidents. Although many of these patients reported somnolence while on levodopa, some perceived that they had no warning signs (sleep attack), such as excessive drowsiness, and believed that they were alert immediately prior to the event. Some of these events have been reported more than one year after initiation of treatment.

Falling asleep while engaged in activities of daily living usually occurs in patients experiencing preexisting somnolence, although patients may not give such a history. For this reason, prescribers should reassess patients for drowsiness or sleepiness in DUOPA-treated patients, especially since some of the events occur well after the start of treatment. Prescribers should be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities. Patients who have already experienced somnolence or an episode of sudden sleep onset should not participate in these activities while taking DUOPA.

Before initiating treatment with DUOPA, advise patients about the potential to develop drowsiness and specifically ask about factors that may increase the risk for somnolence with DUOPA such as the use of concomitant sedating medications or the presence of sleep disorders. Consider discontinuing DUOPA in patients who report significant daytime sleepiness or episodes of falling asleep during activities that require active participation (e.g., conversations, eating). If DUOPA is continued, they should be advised to avoid driving and other potentially dangerous activities that might result in harm if the patient becomes somnolent.

5.3 Orthostatic Hypotension

DUOPA-treated patients were more likely to experience a decline in orthostatic blood pressure than patients treated with oral immediate-release carbidopa-levodopa in the controlled clinical study. Orthostatic systolic hypotension (≥30 mm Hg decrease) occurred in 73% of DUOPA-treated patients compared to 68% of patients treated with oral immediate-release carbidopa-levodopa in the controlled clinical study. Orthostatic diastolic hypotension (≥20 mm Hg decrease) occurred in 70% of DUOPA-treated patients compared to 62% of patients treated with oral immediate-release carbidopa-levodopa. Inform patients about the risk for hypotension and syncope. Monitor patients for orthostatic hypotension, especially after starting DUOPA or increasing the dose.

5.4 Hallucinations/Psychosis/Confusion

There is an increased risk for hallucinations and psychosis in patients taking DUOPA. In the controlled clinical trial, hallucinations occurred in 5% of DUOPA-treated patients compared to 3% of patients treated with oral immediate-release carbidopa-levodopa. Confusion occurred in 8% of DUOPA-treated patients compared to 3% of patients treated with oral immediate-release carbidopa-levodopa, and psychotic disorder occurred in 5% of DUOPA-treated patients compared to 3% of patients treated with oral immediate-release carbidopa-levodopa.

Hallucinations associated with levodopa may present shortly after the initiation of therapy and may be responsive to dose reduction in levodopa. Confusion, insomnia, and excessive dreaming may accompany hallucinations. Abnormal thinking and behavior may present with one or more symptoms, including paranoid ideation, delusions, hallucinations, confusion, psychosis, disorientation, aggressive behavior, agitation, and delirium.

Because of the risk of exacerbating psychosis, patients with a major psychotic disorder should not be treated with DUOPA. In addition, medications that antagonize the effects of dopamine used to treat psychosis may exacerbate the symptoms of Parkinson’s disease and may decrease the effectiveness of DUOPA [see Drug Interactions ( 7.3)].

5.5 Impulse Control/Compulsive Behaviors

Patients may experience intense urges to gamble, increased sexual urges, intense urges to spend money, binge or compulsive eating, and/or other intense urges, and the inability to control these urges while taking one or more of the medications, including DUOPA, that increase central dopaminergic tone and that are generally used for the treatment of Parkinson’s disease. In some cases, although not all, these urges were reported to have stopped when the dose was reduced or the medication was discontinued.

Because patients may not recognize these behaviors as abnormal, it is important for prescribers to ask patients or their caregivers specifically about the development of new or increased gambling urges, sexual urges, uncontrolled spending, binge or compulsive eating, or other urges while being treated with DUOPA. Consider reducing the dose or discontinuing DUOPA if a patient develops such urges.

5.6 Depression and Suicidality

In the controlled clinical trial, 11% of DUOPA-treated patients developed depression compared to 3% of oral immediate-release carbidopa-levodopa-treated patients.

Monitor patients for the development of depression and concomitant suicidal tendencies.

5.7 Withdrawal-Emergent Hyperpyrexia and Confusion

A symptom complex that resembles neuroleptic malignant syndrome (characterized by elevated temperature, muscular rigidity, altered consciousness, and autonomic instability), with no other obvious etiology, has been reported in association with rapid dose reduction, withdrawal of, or changes in dopaminergic therapy. Avoid sudden discontinuation or rapid dose reduction in patients taking DUOPA. If DUOPA is discontinued, the dose should be tapered to reduce the risk of hyperpyrexia and confusion [see Dosage and Administration ( 2.4)].

5.8 Dyskinesia

DUOPA may cause or exacerbate dyskinesias. In the controlled clinical trial, dyskinesia occurred in 14% of DUOPA-treated patients compared to 12% of patients treated with oral immediate-release carbidopa-levodopa. The occurrence of dyskinesias may require a dosage reduction of DUOPA or other medications used to treat Parkinson’s disease.

5.9 Neuropathy

In clinical studies, 19 of 412 (5%) patients treated with DUOPA developed a generalized polyneuropathy. The onset of neuropathy could be determined in 13 of 19 patients. Most cases (12/19) were classified as subacute or chronic in onset. The neuropathy was most often characterized as sensory or sensorimotor. Electrodiagnostic testing performed in 16 patients was most often (15/16) consistent with an axonal polyneuropathy, and one patient was classified as having a demyelinating neuropathy. There was insufficient information to determine the potential role of vitamin deficiencies in the etiology of neuropathy associated with DUOPA.

Patients should have clinical assessments for the signs and symptoms of peripheral neuropathy before starting DUOPA. Monitor patients periodically for signs of neuropathy after starting DUOPA, especially in patients with pre-existing neuropathy and in patients taking medications or those who have medical conditions that are also associated with neuropathy.

5.10 Cardiovascular Ischemic Events

In clinical studies, myocardial infarction and arrhythmia were reported in patients taking carbidopa-levodopa. Ask patients about symptoms of ischemic heart disease and arrhythmia, especially those with a history of myocardial infarction or cardiac arrhythmias.

5.11 Laboratory Test Abnormalities

DUOPA may increase the risk for elevated (above the upper limit of normal for the reference range) blood urea nitrogen (BUN) and creatine phosphokinase (CPK). In the controlled clinical trial, the shift from a low or normal value at baseline to an increased BUN value was greater for DUOPA-treated patients (13%) than for patients treated with oral immediate-release carbidopa-levodopa (4%). The shift from a low or normal value at baseline to an increased CPK value was greater for DUOPA-treated patients (17%) than for patients treated with oral immediate-release carbidopa-levodopa (7%). The incidence of patients with a markedly increased BUN (≥10 mmol/L; ≥28 mg/dL) was greater for patients treated with DUOPA (11%) than that for patients treated with oral immediate-release carbidopa-levodopa (0%). The incidence of patients with an increased CPK (>3 times the upper limit of normal) was greater for patients treated with DUOPA (9%) than that for patients treated with oral immediate-release carbidopa-levodopa (0%).

Patients taking levodopa or carbidopa-levodopa may have increased levels of catecholamines and their metabolites in plasma and urine giving false positive results suggesting the diagnosis of pheochromocytoma in patients on levodopa and carbidopa-levodopa.

5.12 Glaucoma

Carbidopa-levodopa may cause increased intraocular pressure in patients with glaucoma. Monitor intraocular pressure in patients with glaucoma after starting DUOPA.

6.1 Clinical Trials Experience

Because clinical studies are run under widely varying conditions, the incidence of adverse reactions 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.

In clinical studies, 416 patients with advanced Parkinson’s disease received DUOPA. 338 patients were treated with DUOPA for more than 1 year, 233 patients were treated with DUOPA for more than 2 years, and 162 patients were treated with DUOPA for more than 3 years.

In a 12-week, active-controlled clinical trial (Study 1), a total of 71 patients with advanced Parkinson’s disease were enrolled and had a PEG-J procedure. Of these, 37 patients received DUOPA and 34 received oral immediate-release carbidopa-levodopa.

The most common adverse reactions for DUOPA (incidence at least 7% greater than oral immediate-release carbidopa-levodopa) were: complication of device insertion, nausea, depression, peripheral edema, hypertension, upper respiratory tract infection, oropharyngeal pain, atelectasis, and incision site erythema.

Table 3 lists the incidence of adverse reactions occurring in the DUOPA-treated group (requiring at least 2 patients in this group) in Study 1 when the incidence was numerically greater than that for oral immediate-release carbidopa-levodopa.

Procedure and Device- Related Adverse Reactions

The most common adverse reactions associated with complications due to naso-jejunal (NJ) insertion were: oropharyngeal pain, abdominal distention, abdominal pain, abdominal discomfort, pain, throat irritation, gastrointestinal injury, esophageal hemorrhage, anxiety, dysphagia, and vomiting.

The most common adverse reactions associated with complications due to PEG-J insertion were: abdominal pain, abdominal discomfort, abdominal distension, flatulence, or pneumoperitoneum.

Additional adverse reactions that were co-reported with complication of naso-jejunal and PEG-J insertion included upper abdominal pain, duodenal ulcer, duodenal ulcer hemorrhage, erosive duodenitis, erosive gastritis, gastrointestinal hemorrhage, intussusception, peritonitis, post-operative abscess, and small intestine ulcer.

7.1 Monoamine Oxidase (MAO) Inhibitors

The use of nonselective MAO inhibitors with DUOPA is contraindicated [see Contraindications ( 4)]. Discontinue use of any nonselective MAO inhibitors at least two weeks prior to initiating DUOPA.

The use of selective MAO-B inhibitors (e.g., rasagiline and selegiline) with DUOPA may be associated with orthostatic hypotension. Monitor patients who are taking these drugs.

7.2 Antihypertensive Drugs

The concurrent use of DUOPA with antihypertensive medications can cause symptomatic postural hypotension. A dose reduction of the antihypertensive medication may be needed after starting or increasing the dose of DUOPA.

7.3 Dopamine D2 Receptor Antagonists and Isoniazid

Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone, metoclopramide, papaverine) and isoniazid may reduce the effectiveness of levodopa. Monitor patients for worsening Parkinson’s symptoms.

7.4 Iron Salts

Iron salts or multi-vitamins containing iron salts can form chelates with levodopa, carbidopa, and can cause a reduction in the bioavailability of DUOPA. If iron salts or multi-vitamins containing iron salts are co-administered with DUOPA, monitor patients for worsening Parkinson’s symptoms.

7.5 High-Protein Diet

Because levodopa competes with certain amino acids for transport across the gut wall, the absorption of levodopa may be decreased in patients on a high-protein diet. Advise patients that a high-protein diet may reduce the effectiveness of DUOPA.

DUOPA is a combination of carbidopa, an inhibitor of aromatic amino acid decarboxylation, and levodopa, an aromatic amino acid.

Carbidopa is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.2. It is designated chemically as (2S)-3-(3,4-dihydroxyphenyl)-2-hydrazino-2-methylpropanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O, and its structural formula is:

carbidopa chem structure

The content of carbidopa in DUOPA is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.3. The 4.63 mg/mL of anhydrous carbidopa is equivalent to 5.0 mg/mL of carbidopa.

Levodopa is a white, crystalline compound, slightly soluble in water, with a molecular weight of 197.2. It is designated chemically as (2S)-2-Amino-3-(3,4-dihydroxyphenyl) propanoic acid. Its empirical formula is C9H11NO4, and its structural formula is:

levodopa chem structure

The inactive ingredients in DUOPA are carmellose sodium and purified water.

12.1 Mechanism of Action

Carbidopa

When levodopa is administered orally, it is rapidly decarboxylated to dopamine in extracerebral tissues so that only a small portion of a given dose is transported unchanged to the central nervous system. Carbidopa inhibits the decarboxylation of peripheral levodopa, making more levodopa available for delivery to the brain.

Levodopa

Levodopa is the metabolic precursor of dopamine, does cross the blood-brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa treats the symptoms of Parkinson's disease.

12.2 Pharmacodynamics

Because its decarboxylase inhibiting activity is limited to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available to the brain. The addition of carbidopa to levodopa reduces the peripheral effects (e.g., nausea and vomiting) due to decarboxylation of levodopa; however, carbidopa does not decrease the adverse reactions due to the central effects of levodopa.

12.3 Pharmacokinetics

The pharmacokinetics of carbidopa and levodopa with 16-hour intrajejunal infusion of DUOPA was evaluated in 18 patients with advanced Parkinson's disease who had been on DUOPA therapy for 30 days or longer. Patients remained on their individualized DUOPA doses.

The plasma concentrations versus time profile for levodopa with DUOPA 16-hour intrajejunal infusion is presented in Figure 1.

Figure 1. Plasma Concentrations (mean ± standard deviation) versus Time Profile of Levodopa with DUOPA (levodopa, 1580 ± 403 mg; carbidopa, 366 ± 92 mg) 16-Hour Infusion

Absorption and Bioavailability

Following initiation of the 16-hour intrajejunal infusion of DUOPA, peak plasma levels of levodopa is reached at 2.5 hours. The absorption of levodopa may be decreased in patients on a high-protein diet because levodopa competes with certain amino acids for transport across the gut wall. The gastric emptying rate does not influence the absorption of DUOPA since it is administered by continuous intestinal infusion. In a cross-study population pharmacokinetic analysis, DUOPA had comparable bioavailability to the oral immediate-release carbidopa-levodopa (25/100 mg) tablets (over-encapsulated tablets). The estimated bioavailability for levodopa from DUOPA relative to oral immediate-release carbidopa-levodopa tablets was 97% (95% confidence interval; 95% to 98%).

In the controlled clinical trial, the intra-subject variability in carbidopa and levodopa plasma concentrations were lower for patients treated with DUOPA (N=33, 25% and 21%, respectively) than in patients treated with oral immediate-release carbidopa-levodopa (25/100 mg) tablets (N=28, 39% and 67%, respectively).

Distribution

Carbidopa is approximately 36% bound to plasma proteins. Levodopa is approximately 10-30% bound to plasma proteins.

Metabolism and Elimination

Carbidopa

Carbidopa is metabolized to two main metabolites (α-methyl-3-methoxy-4-hydroxyphenylpropionic acid and α-methyl-3,4-dihydroxyphenylpropionic acid). These 2 metabolites are primarily eliminated in the urine unchanged or as glucuronide conjugates. Unchanged carbidopa accounts for 30% of the total urinary excretion. The elimination half-life of carbidopa is approximately 2 hours.

Levodopa

Levodopa is mainly eliminated via metabolism by the aromatic amino acid decarboxylase (AAAD) and the catechol-O-methyl-transferase (COMT) enzymes. Other routes of metabolism are transamination and oxidation. The decarboxylation of levodopa to dopamine by AAAD is the major enzymatic pathway when no enzyme inhibitor is co-administered. O-methylation of levodopa by COMT forms 3-O-methyldopa. When administered with carbidopa, the elimination half-life of levodopa is approximately 1.5 hours (see Figure 1).

Drug Interaction Studies

COMT Inhibitors

Systemic exposure of levodopa is expected to increase in the presence of entacapone.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

In rat, oral administration of carbidopa-levodopa for two years resulted in no evidence of carcinogenicity. DUOPA contains hydrazine, a degradation product of carbidopa. In published studies, hydrazine has been demonstrated to be carcinogenic in multiple animal species. Increases in liver (adenoma, carcinoma) and lung (adenoma, adenocarcinoma) tumors have been reported with oral administration of hydrazine in mouse, rat, and hamster.

Mutagenesis

Carbidopa was positive in the in vitro Ames test, in the presence and absence of metabolic activation, and the in vitro mouse lymphoma tk assay in the absence of metabolic activation but was negative in the in vivo mouse micronucleus assay.

In published studies, hydrazine was reported to be positive in in vitro genotoxicity (Ames, chromosomal aberration in mammalian cells, and mouse lymphoma tk) assays and in the in vivo mouse micronucleus assay.

Impairment of Fertility

In reproduction studies, no effects on fertility were observed in rats receiving carbidopa-levodopa.

The efficacy of DUOPA was established in a randomized, double-blind, double-dummy, active-controlled, parallel group, 12-week study (Study 1) in patients with advanced Parkinson's disease who were levodopa-responsive and had persistent motor fluctuations while on treatment with oral immediate-release carbidopa-levodopa and other Parkinson's disease medications.

Patients were eligible for participation in the studies if they were experiencing 3 hours or more of “Off” time on their current Parkinson's disease drug treatment and they demonstrated a clear responsiveness to treatment with levodopa. Seventy-one (71) patients enrolled in the study and 66 patients completed the treatment (3 patients discontinued treatment because of adverse reactions, 1 patient for lack of effect, and 1 patient for non-compliance).

Patients enrolled in this study had a mean age of 64 years and disease duration of 11 years. Most patients (89%) were taking at least one concomitant medication for Parkinson’s disease (e.g., dopaminergic agonist, COMT-inhibitor, MAO-B inhibitor) in addition to oral immediate-release carbidopa-levodopa. Thirty nine percent of patients were taking two or more of such concomitant medications.

Patients were randomized to either DUOPA and placebo capsules or placebo suspension and oral immediate-release carbidopa-levodopa 25/100 mg capsules. Patients in both treatment arms had a PEG-J device placement. DUOPA or placebo-suspension was infused over 16 hours daily through a PEG-J tube via the CADD®-Legacy 1400 model ambulatory infusion pump. The mean daily levodopa dose was 1117 mg/day in the DUOPA group and 1351 mg/day in the oral immediate-release carbidopa-levodopa group.

The clinical outcome measure in Study 1 was the mean change from baseline to Week 12 in the total daily mean “Off” time, based on a Parkinson's disease diary. The "Off" time was normalized to a 16-hour awake period, based on a typical person's waking day and the daily infusion duration of 16 hours. The mean score decrease (i.e., improvement) in “Off” time from baseline to Week 12 for DUOPA was significantly greater (p=0.0015) than for oral immediate-release carbidopa-levodopa. Additionally, the mean score increase (i.e., improvement) in “On” time without troublesome dyskinesia from baseline to Week 12 was significantly greater (p=0.0059) for DUOPA than for oral immediate-release carbidopa-levodopa. The treatment difference (DUOPA – oral immediate release carbidopa-levodopa) for decrease in “Off” time was approximately 1.9 hours and the treatment difference for the increase in “On” time without troublesome dyskinesia was approximately 1.9 hours. Results of Study 1 are shown in Table 4.

Warnings

This operator’s manual should be used by clinicians only. Do not permit patients to have access to this manual, as the information contained would allow the patient complete access to all programming and operating functions. Improper programming could compromise patient treatment.
To avoid explosion hazard, do not use the pump in the presence of flammable anesthetics or explosive gases.
The CADD-Legacy® 1400 pump and medication cassette reservoir are designed for enteral delivery of medication only. They are NOT intended for IV or other parenteral routes of infusion.
Do not disclose to the patient the pump’s security codes or any other information that would allow the patient complete access to all programming and operating functions. Improper programming could compromise patient treatment.
Always have new batteries available for replacement. If power is lost, non-delivery of medication will occur.
If the pump is dropped or hit, the battery door or tabs may break. Do not use the pump if the battery door or tabs are damaged because the batteries will not be properly secured; this may result in loss of power and non-delivery of medication.
If a gap is present anywhere between the battery door and the pump housing, the door is not properly latched. If the battery door becomes detached or loose, the batteries will not be properly secured; this could result in loss of power and non-delivery of medication.
System delivery inaccuracies beyond the stated accuracy may occur as a result of back pressure or fluid resistance, which depends upon temperature, medication viscosity, catheter size, extension set tubing, flow rate, and orientation of the pump system.
Programming the pump at a delivery rate other than what is prescribed will cause over- or under-delivery of medication.
Clamp the fluid path tubing and/or disconnect the tubing from the enteral access device before removing the medication cassette reservoir from the pump to prevent unintended delivery of medication.
Use only approved DUOPA medication cassette reservoirs to maintain pump accuracy and assure proper pump operations.
Use only extension sets approved for use with DUOPA, paying particular attention to all warnings and cautions associated with their use.
Attach the cassette properly. The cassette is the part of the medication cassette reservoir that attaches to the pump. A detached or improperly attached cassette could result in unintended delivery of medication.
Do not prime the fluid path with the tubing connected to a patient as this could result in over-delivery of medication.
If the pump is dropped or hit, inspect the pump for damage. Do not use a pump that is damaged or is not functioning properly, as this could compromise patient treatment.
The use of power supplies and a remote dose cord other than those listed in the electromagnetic emissions declaration may result in increased emissions or decreased immunity of the pump.
The pump should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is necessary, the user should verify normal operation of the pump in the configuration in which it is to be used.
There are potential health hazards associated with improper disposal of batteries, electronics, and contaminated (used) reservoirs and extension sets. Dispose of used batteries, reservoirs, extension sets and other used accessories, or a pump that has reached the end of its useful life, in an environmentally safe manner, and according to any regulations that may apply.

Cautions

Use only Smiths Medical accessories and replacement parts, as using other brands may adversely affect the operation of the pump.
Do not operate the pump at temperatures below 2°C (36°F) or above 40°C (104°F).
Do not store the pump at temperatures below -20°C (-4°F) or above 60°C (140°F). Do not store the pump with the medication cassette reservoir attached. Use the protective cassette provided.
Do not expose the pump to humidity levels below 20% or above 90% relative humidity.
Do not sterilize the pump or medication cassette reservoir as this could cause damage.
When the upstream occlusion sensor is turned off, the pump will not detect occlusions in the medication cassette reservoir. Periodically inspect the medication cassette reservoir for decreasing volume. Undetected occlusions could result in under- or non-delivery of medication.
Do not use rechargeable NiCd or nickel metal hydride (NiMH) batteries. Do not use carbon zinc (“heavy duty”) batteries. They do not provide sufficient power for the pump to operate properly.
Do not store the pump for prolonged periods of time with the batteries installed. Battery leakage could damage the pump.
Prior to starting medication delivery, inspect the fluid path for kinks, a closed clamp, or other obstruction. An undetected occlusion may result in under- or non-delivery of medication and/or nuisance alarms.
When you enter a new value, any lockout time already in effect will be cleared. An extra dose or morning dose could be requested and delivered immediately upon starting the pump, which may result in over-delivery of medication.
Do not immerse the pump in cleaning fluid or water. Do not allow solution to soak into the pump, accumulate on the keypad, or enter the battery compartment. Moisture buildup inside the pump may damage the pump.
Do not clean the pump with acetone, other plastic solvents, or abrasive cleaners, as damage to the pump may occur.
Do not expose the pump to therapeutic levels of ionizing radiation as permanent damage to the pump’s electronic circuitry may occur. The best procedure to follow is to remove the pump from the patient during therapeutic radiation sessions. If the pump must remain in the vicinity during a therapy session, it should be shielded, and its ability to function properly should be confirmed following treatment.
Do not expose the pump directly to ultrasound, as permanent damage to the electronic circuitry may occur.
Do not use the pump in the vicinity of magnetic resonance imaging (MRI) equipment as magnetic fields may adversely affect the operation of the pump. Remove the pump from the patient during MRI procedures and keep it at a safe distance from magnetic energy.
This pump may interfere with ECG equipment. Monitor ECG equipment carefully when using this pump.
CADD-Legacy® 1400 pumps are sealed units. A broken or damaged seal will, therefore, be considered conclusive evidence that the pump has been misused and/or altered, which voids any and all warranties. All service and repair of CADD-Legacy® 1400 pumps must be performed by Smiths Medical or its authorized agents.
Review programming screens when complete to make sure desired programming has been entered. Check to make sure unintended changes were not made to the morning dose, continuous rate, or extra dose volume. If unintended changes were made, go to the appropriate screen and program the desired value.

Description of the Keys, Display, and Features

AC Indicator Light

The green indicator light is on when you are using the AC adapter to power the pump.

Display

The liquid crystal display (LCD) shows programming information and messages. In this manual, the term “display” is synonymous with display panel or LCD.

Keypad

The keys on the keypad are described below. A key beeps when pressed if it is operable in the current lock level.

	used to start and stop pump delivery; silences alarms.
	used to enter (save) a new value in the pump’s memory when programming doses or pump settings or to clear values from record-keeping screens. It is also used to return from the biomed functions to the main screen (see Section 4).
	used to fill the tubing with medication.
	used to confirm and deliver the morning dose (typically used as a daily loading dose) when the pump is running. When the pump is stopped, it is used to view or change the pump’s current lock level. Lock levels are used to limit patient access to certain programming and operating functions. (See Lock Levels, this section.)
	used to move from one programming screen to the next without changing the setting or value displayed; silences alarms.
	used to “scroll up” or increase a value, or scroll through biomed function settings.
	used to “scroll down” or decrease a value, or scroll through biomed function settings.
	used to put the pump into a low power state when not in use or back into full power.
	used by the patient to deliver a programmed amount of medication upon request (extra dose).

Power Jack

You may plug an AC adapter into the power jack as an alternate source of power. The indicator light on the front of the pump will illuminate when the AC adapter is in use.

Accessory Jack

The accessory jack is used for attaching accessory cables. See the instructions for use supplied with those accessories.

Medication Cassette Reservoir

The medication cassette reservoir is the single-use reservoir designed for use with the CADD-Legacy® 1400 pump. In this manual and on the pump’s display, the word “disposable” refers to the medication cassette reservoir. In AbbVie’s patient instructions for use, medication cassette reservoir is referred to as DUOPA cassette.

Battery Compartment

Two AA batteries fit into the battery compartment. The AA batteries serve as the primary source of power, or as backup power when an AC adapter is in use.

Cassette Latch

The cassette latch attaches the cassette to the pump. The term “cassette” refers to the part of the medication cassette reservoir that attaches to the bottom of the pump. If the cassette becomes unlatched while the pump is running, delivery will stop and an alarm will occur. If the cassette becomes unlatched while the pump is stopped, an alarm will occur.

Other Features Not Shown

Upstream Occlusion Sensor: The pump contains an upstream occlusion sensor. This feature may be turned on or off (see Section 4, Biomed Functions). When the sensor is turned on, and an occlusion in the reservoir is detected, an alarm will sound, delivery will stop, and the display will show Upstream Occlusion.

CAUTION: When the upstream occlusion sensor is turned off, the pump will not detect occlusions in the medication cassette reservoir. Periodically inspect the medication cassette reservoir for decreasing volume. Undetected occlusions could result in under- or non-delivery of medication.

Downstream Occlusion Sensor: The pump contains a downstream occlusion sensor. When a downstream occlusion (between the pump and the patient) is detected, an alarm will sound, delivery will stop, and the display will show High Pressure.

Reservoir Volume Alarm: The reservoir volume alarm indicates when the volume of medication in the medication cassette reservoir is low or depleted. Each time you change the medication cassette reservoir, you may reset the reservoir volume to the originally programmed value. Then, as medication is delivered, the reservoir volume automatically decreases. When the pump calculates that 5 ml remain in the medication cassette reservoir, beeps sound and ResVol Low appears on the main screen. This alarm recurs at every subsequent decrease of 1 ml until the reservoir volume reaches 0 ml, at which point the pump stops and the reservoir volume empty alarm sounds.

NOTE: The default setting for Reservoir Volume is Not in Use. The reservoir volume alarm is activated only when a value is programmed into the Reservoir Volume screen. Programming a reservoir volume value is not required for general use, but is available at provider discretion.

The Main Screen

The main screen is the starting point for programming or viewing the pump’s settings.

If no keys are pressed for 2 minutes, the display reverts to the main screen. When the two AA batteries are low, LowBat appears on the main screen.

Lock Levels

Lock levels are used to limit patient access to certain programming and operating functions. The table on the next page lists the functions that are accessible in lock level 0 (LL0), lock level 1 (LL1), and lock level 2 (LL2). When a function is accessible, the key associated with the function beeps when pressed. If a function is not accessible, the pump ignores the key press and a beep does not sound. Section 2, Pump Setup and Programming, describes how to change the lock level.

Security Codes

The following security codes are preset by the manufacturer for the clinician’s use:

2.0 Pump Setup and Programming

Installing or Replacing the Batteries

Use new, AA alkaline batteries such as DURACELL® or EVEREADY® ENERGIZER® batteries to power the pump. The pump retains all programmed values while the batteries are removed.

Dispose of used batteries in an environmentally safe manner, and according to any regulations which may apply.

WARNING:
Always have new batteries available for replacement. If power is lost, non-delivery of medication will occur, which could compromise patient treatment.
If the pump is dropped or hit, the battery door or tabs may break. Do not use the pump if the battery door or tabs are damaged because the batteries will not be properly secured; this may result in loss of power and non-delivery of medication, which could compromise patient treatment.

CAUTION: Do not use rechargeable NiCd or nickel metal hydride (NiMH) batteries. Do not use carbon zinc (“heavy duty”) batteries. They do not provide sufficient power for the pump to operate properly.

In order to install or replace the batteries, be sure the pump is Stopped. Then, follow these steps:

1. Push down and hold the arrow button while sliding the door off.

open battery door

2. Remove the used batteries. Pulling on the end of the battery strap will make battery removal easier.

install battery with strap

NOTE:

Be sure to match the polarity markings of the new batteries (+ and –) with those labeled in the battery compartment. If you put the batteries in backwards, the display will remain blank, and you will not hear a beep.
Use two new, AA alkaline batteries to power the pump. You may use any alkaline batteries, including DURACELL® Alkaline and EVEREADY® ENERGIZER® Alkaline, for example.

4. Place the battery door over the battery compartment and slide the door closed.

close battery door

5. Ensure that the door is latched by trying to remove the door without pressing the arrow button.

NOTE: The power-up sequence will start, the pump will go through an electronic self-test, and the pump will beep 6 times at the end of the power-up sequence. All of the display indicators, the software revision, and each parameter will appear briefly.

WARNING: If a gap is present anywhere between the battery door and the pump housing, the door is not properly latched. If the battery door becomes detached or loose, the batteries will not be properly secured; this could result in loss of power and non-delivery of medication, which could compromise patient treatment.

improper closed battery door

6. Resume operation of the current program by pressing and holding

stop-start-button

to start the pump or proceed to program the pump.

NOTE:

The life of the batteries is dependent on the amount of medication delivered, delivery rate, battery age, and the temperature.
At the rate of 100 ml per day, alkaline batteries will usually last about 7 days.
The power of the batteries will be quickly depleted at temperatures below 10°C (50°F).

CAUTION: Do not store the pump for prolonged periods of time with the batteries installed. Battery leakage could damage the pump.

Watching Power Up

When you install the batteries, the pump will start its power up sequence during which it performs self-tests and displays programmed values. Watch for the following:

Pump model number and last error code (“LEC”) if any, will appear. (If an error code appears, the pump should be removed from use and returned for service.)
The software revision will appear.
The display will turn on, showing a series of blocks. Look for any blank areas, which would indicate a faulty display.
The display will turn off briefly.
The pump’s program screens will appear, followed by the current lock level setting. The pump will beep after each screen. If messages appear, see Messages and Alarms Table, Section 5 for further explanation and instruction.
When power up is complete, 6 beeps will sound, and the pump will be stopped on the main screen.

These are the programming screens for the CADD-Legacy® 1400 pump. Descriptions of the screens follow.

Reservoir Volume (ml)
Continuous Rate (ml/hr)
Extra Dose (ml)
Given (ml)

Reservoir Volume

NOTE: The default setting for Reservoir Volume is Not in Use. Programming a reservoir volume value is not required for general use, but is available at provider discretion.

If you wish to use the reservoir volume feature, enter the volume of medication contained in the filled medication cassette reservoir. The reservoir volume value decreases as the pump delivers medication or as you prime the tubing. When you change the medication cassette reservoir, reset the reservoir volume value on this screen. If you do not wish to use the reservoir volume feature, scroll down to Not In Use (located before 1 and after 9999 in the range of values).

The reservoir volume value could be set higher than the capacity of the medication cassette reservoir. Be sure to program the reservoir volume to reflect the actual volume in the reservoir.

Continuous Rate

Enter the continuous rate of medication delivery in ml/hr. The maximum rate is 20 ml/hr. If the prescription does not call for a continuous rate, enter zero.

NOTE: If you intend to run the pump in lock level 1 so the continuous rate can be varied, you should enter the maximum allowable rate while programming in lock level 0. After programming, you may then change to lock level 1 and decrease the rate to its starting value. See Programming with Upper Limits, Adjusting Doses in LL1 at the end of Section 2.

Extra Dose

Enter the amount of medication to be delivered when the patient presses

extra dose button

If the prescription does not call for an extra dose, enter zero.

NOTE: If you intend to run the pump in lock level 1 so the extra dose can be varied, you should enter the maximum allowable dose while programming in lock level 0. After programming, you may then change to lock level 1 and decrease the dose to its starting value. See Programming with Upper Limits, Adjusting Doses in LL1 at the end of Section 2.

Given

This screen shows the total amount of medication delivered since the last time this value was cleared. The amount shown is rounded to the nearest 0.05 ml. If this value reaches 99999.95, it automatically returns to 0 and continues counting. When using the pump’s

Safety Features and Fault Detection

Hardware Safety Features

Key hardware safety features include a watchdog timer circuit, motor driver and motor watchdog circuits, and a voltage detector circuit. Each safety circuit performs a unique function to insure the overall safety of the device.

Watchdog Timer Circuit

The microprocessor must send an appropriate signal to the watchdog circuit at least once per second. If the microprocessor does not, the watchdog circuit will time out and shut down the pump controller.

Watchdog timer circuitry is provided to monitor the status of the microprocessor and disable the motor and enable the audible alarm if the microprocessor fails to function properly. The microprocessor must strobe the watchdog circuit at least once every second in order to prevent the watchdog from performing its reset function. The reset output from the watchdog circuit is a pulse output. This acts to “jump startˮ the microprocessor. This unique feature allows the microprocessor to test the watchdog circuit on every power-up.

By setting a flag in the memory and not strobing the watchdog, the microprocessor can force a watchdog time-out. After being reset, the microprocessor checks the status flag to see if this was a time-out test. If so, the microprocessor continues normal power-up activities. If the reset occurred when the microprocessor was not expecting it, the microprocessor traps the event, sounds the audible alarm and displays an error message on the LCD.

Motor Driver/Motor Watchdog Circuit

Motor drive circuitry is composed of a series of power FET transistors, passive components, and 2 voltage comparators. Built into the motor drive circuitry is an RC timer which times how long the motor runs each time it is turned on. If the motor runs for more than an average of 3 seconds, the circuit will time out and disable the motor. A unique feature of this circuit is that control lines to and from the microprocessor circuit allow the microprocessor to perform a complete functional test of the motor drive circuit without running the motor. The microprocessor performs this test function every several minutes to assure its continued functionality. An input from the watchdog circuit prevents motor operation if the watchdog timer expires. The software verifies this function during the watchdog test described above.

Voltage Detector Circuit

Low voltage detection is performed by part of the watchdog circuit and by the microprocessor via software. Three low voltage levels are detected. The first 2 levels are detected by software and the third by hardware. The first level to be reached is the low battery warning threshold which occurs when the battery voltage decays to a nominal value of 2.4 volts when the motor is off or 1.8 volts when the motor is active. An analog to digital converter (ADC) built into the microprocessor allows the microprocessor, via software, to monitor the battery voltage. At the low battery warning threshold, the microprocessor enables a periodic series of beeps and displays a low battery warning message on the LCD. As the voltage operating the motor reaches a nominal value of 4.75 volts, the software disables delivery, places a battery depleted message on the LCD, and enables a constant two tone audible alarm. When the battery voltage decays to a nominal value of 1.0 volts, a hardware reset circuit is triggered which places the microprocessor in reset. This prevents ambiguous microprocessor operation when the battery voltage continues to decay. The hardware reset continues until the battery is completely discharged or until it is removed. Once the pump controller goes into low battery shutdown, only replacing the depleted batteries with new ones will clear the condition.

Software Safety Features

Hardware-related Software Safety Features

Program Memory Check

At power up and at regular intervals thereafter, the program memory is tested by calculating a cyclic redundancy code (CRC) on the program and then comparing it with the CRC stored with the program.

If the stored and calculated CRCs do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

RAM Memory Check

At power up, the random access memory is checked. A series of bit patterns is written to and read from each address in the RAM. If the read data is different from the written data, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Motor Circuit Check

At power up and at regular intervals thereafter, the motor circuit is checked to ensure that no power is being applied to the motor unless the motor is actually on. If the software detects power being applied to the motor at any other time, it will sound a continuous two-tone audible alarm and will no longer attempt to deliver medication. During every pump activation, the software checks to see whether the motor completes one activation. If the motor fails to turn, or fails to complete a cycle, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Keyboard Encoder Check

Every time the software receives data from the keyboard encoder, it is checked. If the data is not a valid key press, the software will disregard the key press. The keyboard is designed with redundant switches for

Prime

extra dose button

, and

stop-start-button

. The software must detect that both switches are activated before taking any action.

Data Handling Software Safety Features

Data Stored in RAM

Before use, data associated with delivery and stored in RAM is tested by calculating a CRC on the data and then comparing it with the CRC stored with the data. If the stored and calculated CRCs do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Data Stored in EEPROM

Before use, data associated with delivery and stored in EEPROM is tested by calculating a CRC on the data and then comparing it with the CRC stored with the data. If the stored and calculated CRCs do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Data Stored in NOVRAM

Before use, data associated with delivery and stored in NOVRAM is tested by calculating a CRC on the data and then comparing it with the CRC stored with the data. If the stored and calculated CRCs do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Data Used in Calculations

Calculations on data used in some way to control the delivery of medication are performed redundantly.

The two calculated values are then compared. If the two values do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Timer Data Registers

The data in the real time clock is checked at regular intervals. If the data is not reasonable, the software will turn on a continuous two-tone audible alarm and stop all medication delivery.

Annual Functional Inspection

Smiths Medical recommends annual functional inspections and tests on the CADD-Legacy® 1400 pump. Contact Smiths Medical to coordinate return and inspection of the pump.

CAUTION: CADD-Legacy® 1400 pumps are sealed units. A broken or damaged seal will, therefore, be considered conclusive evidence that the pump has been misused and/or altered, which voids any and all warranties. All service and repair of CADD-Legacy® 1400 pumps must be performed by Smiths Medical or its authorized agents.
