`FULL PRESCRIBING INFORMATION
`
`
`
`WARNING: RISK OF SERIOUS DEHYDRATION IN PEDIATRIC PATIENTS
`• TRULANCE is contraindicated in patients less than 6 years of age; in nonclinical studies in young
`juvenile mice administration of a single oral dose of plecanatide caused deaths due to dehydration
`[see Contraindications (4), Use in Specific Populations (8.4)].
`• Avoid use of TRULANCE in patients 6 years to less than 18 years of age [see Warnings and
`Precautions (5.1), Use in Specific Populations (8.4)].
`• The safety and effectiveness of TRULANCE have not been established in patients less than 18
`years of age [see Use in Specific Populations (8.4)].
`1 INDICATIONS AND USAGE
`TRULANCE is indicated in adults for the treatment of chronic idiopathic constipation (CIC).
`2 DOSAGE AND ADMINISTRATION
`2.1 Recommended Dosage
`The recommended dosage of TRULANCE is 3 mg taken orally once daily.
`2.2 Preparation and Administration Instructions
`• Take TRULANCE with or without food [see Clinical Pharmacology (12.3)].
`If a dose is missed, skip the missed dose and take the next dose at the regular time. Do not take two
`•
`doses at the same time.
`• Swallow a tablet whole for each dose.
`• For adult patients with swallowing difficulties, TRULANCE tablets can be crushed and administered
`orally either in applesauce or with water or administered with water via a nasogastric or gastric
`feeding tube. Mixing TRULANCE crushed tablets in other soft foods or in other liquids has not
`been tested.
`Oral Administration in Applesauce:
`1. In a clean container, crush the TRULANCE tablet to a powder and mix with 1 teaspoonful of room
`temperature applesauce.
`2. Consume the entire tablet-applesauce mixture immediately. Do not store the mixture for later use.
`Oral Administration in Water:
`1. Place the TRULANCE tablet in a clean cup.
`2. Pour approximately 30 mL of room temperature water into the cup.
`3. Mix by gently swirling the tablet and water mixture for at least 10 seconds. The TRULANCE tablet
`will fall apart in the water.
`4. Swallow the entire contents of the tablet water mixture immediately.
`5. If any portion of the tablet is left in the cup, add another 30 mL of water to the cup, swirl for at least
`10 seconds, and swallow immediately.
`6. Do not store the tablet-water mixture for later use.
`Administration with Water via a Nasogastric or Gastric Feeding Tube:
`1. Place the TRULANCE tablet in a clean cup with 30 mL of room temperature water.
`2. Mix by gently swirling the tablet and water mixture for at least 15 seconds. The TRULANCE tablet
`will fall apart in the water.
`3. Flush the nasogastric or gastric feeding tube with 30 mL of water using an appropriate syringe.

`
`
`4. Draw up the mixture using the syringe and immediately administer via the nasogastric or gastric
`feeding tube. Do not reserve for future use.
`5. If any portion of the tablet is left in the cup, add another 30 mL of water to the cup, swirl for at least
`15 seconds, and using the same syringe, administer via the nasogastric or gastric feeding tube.
`6. Using the same or a fresh syringe, flush the nasogastric or gastric feeding tube with at least 10 mL of
`water.
`3 DOSAGE FORMS AND STRENGTHS
`TRULANCE Tablets:
`3 mg: white to off-white, plain, round tablet debossed with “SP” on one side and “3” for 3 mg on the other side.
`4 CONTRAINDICATIONS
`TRULANCE is contraindicated in:
`• Patients less than 6 years of age due to the risk of serious dehydration [see Warnings and Precautions
`(5.1), Use in Specific Populations (8.4)].
`• Patients with known or suspected mechanical gastrointestinal obstruction.
`5 WARNINGS AND PRECAUTIONS
`5.1 Risk of Serious Dehydration in Pediatric Patients
`TRULANCE is contraindicated in patients less than 6 years of age. The safety and effectiveness of
`TRULANCE in patients less than 18 years of age have not been established. In young juvenile mice (human
`age equivalent of approximately 1 month to less than 2 years), plecanatide increased fluid-secretion into the
`intestines as a consequence of stimulation of guanylate cyclase-C (GC-C), resulting in mortality in some mice
`within the first 24 hours, apparently due to dehydration. Due to increased intestinal expression of GC-C,
`patients less than 6 years of age may be more likely than patients 6 years of age and older to develop severe
`diarrhea and its potentially serious consequences.
`Avoid the use of TRULANCE in patients 6 years to less than 18 years of age. Although there were no deaths in
`older juvenile mice, given the deaths in younger mice and the lack of clinical safety and efficacy data in
`pediatric patients, avoid the use of TRULANCE in patients 6 years to less than 18 years of age [see
`Contraindications (4), Warnings and Precautions (5.2), Use in Specific Populations (8.4)].
`5.2 Diarrhea
`Diarrhea was the most common adverse reaction in the two placebo-controlled clinical trials. Severe diarrhea
`was reported in 0.6% of patients [see Adverse Reactions (6.1)]. If severe diarrhea occurs, suspend dosing and
`rehydrate the patient.
`6 ADVERSE REACTIONS
`6.1 Clinical Trials Experience
`Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the
`clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not
`reflect the rates observed in practice.
`The safety data described below reflect data from 1733 adult patients with CIC randomized in two double-blind,
`placebo-controlled clinical trials (Study 1 and Study 2) to receive placebo or 3 mg of TRULANCE once daily
`for 12 weeks. Demographic characteristics were comparable between the TRULANCE and placebo groups
`[see Clinical Studies (14)].

`Diarrhea
`The majority of reported cases of diarrhea occurred within 4 weeks of treatment initiation. Severe diarrhea was
`reported in 0.6% of TRULANCE-treated patients compared to 0.3% of placebo-treated patients. Severe
`diarrhea was reported to occur within the first 3 days of treatment [see Warnings and Precautions (5.2)].
`Adverse Reactions Leading to Discontinuation
`Discontinuations due to adverse reactions occurred in 4% of TRULANCE-treated patients and 2% of
`placebo-treated patients. The most common adverse reaction leading to discontinuation was diarrhea: 2% of
`TRULANCE-treated patients and 0.5% of placebo-treated patients withdrew due to diarrhea.
`Less Common Adverse Reactions
`Adverse reactions reported in less than 2% of TRULANCE-treated patients and at an incidence greater than
`placebo were: sinusitis, upper respiratory tract infection, abdominal distension, flatulence, abdominal
`tenderness, and increased liver biochemical tests (2 patients with alanine aminotransferase (ALT) greater than 5
`to 15 times the upper limit of normal and 3 patients with aspartate aminotransferase (AST) greater than 5 times
`the upper limit of normal).
`8 USE IN SPECIFIC POPULATIONS
`8.1 Pregnancy
`Risk Summary
`Plecanatide and its active metabolite are negligibly absorbed systemically following oral administration [see
`Clinical Pharmacology (12.3)] and maternal use is not expected to result in fetal exposure to the drug. The
`available data on TRULANCE use in pregnant women are not sufficient to inform any drug-associated risks for
`major birth defects and miscarriage. In animal developmental studies, no effects on embryo-fetal development
`were observed with oral administration of plecanatide in mice and rabbits during organogenesis at doses much
`higher than the recommended human dosage.
`The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
`All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the United States
`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
`Pregnant mice and rabbits were administered plecanatide during the period of organogenesis. There was no
`evidence of harm to embryo-fetal development at oral doses up to 800 mg/kg/day in mice and 250 mg/kg/day in
`
`Reference ID: 4044252
`
`4
`
`

`

`
`
`rabbits. Oral administration of up to 600 mg/kg/day in mice during organogenesis through lactation produced
`no developmental abnormalities or effects on growth, learning and memory, or fertility in the offspring through
`maturation.
`The maximum recommended human dose is approximately 0.05 mg/kg/day, based on a 60-kg body weight.
`Limited systemic exposure to plecanatide was achieved in animals during organogenesis (area under the plasma
`concentration-time curve [AUCt] = 449 ng•h/mL in rabbits given 250 mg/kg/day). Plecanatide and its active
`metabolite are not measurable in human plasma following administration of the recommended clinical dosage.
`Therefore, animal and human doses should not be compared directly for evaluating relative exposure.
`8.2 Lactation
`Risk Summary
`There is no information regarding the presence of plecanatide in human milk, or its effects on milk production
`or the breastfed infant. No lactation studies in animals have been conducted. Plecanatide and its active
`metabolite are negligibly absorbed systemically following oral administration [see Clinical Pharmacology
`(12.3)].
`It is unknown whether the negligible systemic absorption of plecanatide by adults will result in a clinically
`relevant exposure to breastfed infants. Exposure to plecanatide in breastfed infants has the potential for serious
`adverse effects [see Use in Special Populations (8.4)]. The developmental and health benefits of breastfeeding
`should be considered along with the mother’s clinical need for TRULANCE and any potential adverse effects
`on the breastfed infant from TRULANCE or from the underlying maternal condition.
`8.4 Pediatric Use
`TRULANCE is contraindicated in pediatric patients less than 6 years of age. Avoid use of TRULANCE in
`patients 6 years to less than 18 years of age [see Contraindications (4), Warnings and Precautions (5.1)]. The
`safety and effectiveness of TRULANCE in patients less than 18 years of age have not been established.
`In nonclinical studies, deaths occurred within 24 hours in young juvenile mice (human age equivalent of
`approximately 1 month to less than 2 years) following oral administration of plecanatide, as described below in
`Juvenile Animal Toxicity Data. Because of increased intestinal expression of GC-C, patients less than 6 years
`of age may be more likely than patients 6 years of age and older to develop diarrhea and its potentially serious
`consequences. TRULANCE is contraindicated in patients less than 6 years of age. Given the deaths in young
`juvenile mice and the lack of clinical safety and efficacy data in pediatric patients, avoid the use of
`TRULANCE in patients 6 years to less than 18 years of age.
`Juvenile Animal Toxicity Data
`Single oral doses of plecanatide at 0.5 mg/kg and 10 mg/kg caused mortality in young juvenile mice on
`postnatal days 7 and 14, respectively (human age equivalent of approximately 1 month to less than 2 years).
`Treatment-related increases in the weight of intestinal contents were observed in juvenile mice following single
`doses of plecanatide on postnatal day 14 (human age equivalent of approximately less than 2 years), consistent
`with increased fluid in the intestinal lumen. Although the recommended human dose is approximately 0.05
`mg/kg/day, based on a 60-kg body weight, plecanatide and its active metabolite are not measurable in adult
`human plasma, whereas systemic absorption was demonstrated in the juvenile animal toxicity studies. Animal
`and human doses should not be compared directly for evaluating relative exposure.
`8.5 Geriatric Use
`Clinical studies of TRULANCE did not include sufficient numbers of patients aged 65 and over to determine
`whether they respond differently from patients 18 years to less than 65 years of age. Of 2601 subjects in
`clinical trials of TRULANCE, 273 (10%) were 65 years of age and over, and 47 (2%) were 75 years and over.

`
`In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased
`hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
`11 DESCRIPTION
`TRULANCE (plecanatide) is a guanylate cyclase-C (GC-C) agonist. Plecanatide is a 16 amino acid peptide
`with the following chemical name: L-Leucine, L-asparaginyl-L-α-aspartyl-L-α-glutamyl-L-cysteinyl-L-α-
`glutamyl-L-leucyl-L-cysteinyl-L-valyl-L-asparaginyl-L-valyl-L-alanyl-L-cysteinyl-L-threonylglycyl-L-
`cysteinyl-, cyclic (4→12),(7→15)-bis(disulfide).
`The molecular formula of plecanatide is C65H104N18O26S4 and the molecular weight is 1682 Daltons. The amino
`acid sequence for plecanatide is shown below:
`S
`S
`H-Asn1-Asp2-Glu3-Cys4-Glu5-Leu6-Cys7-Val8-Asn9-Val10-Ala11-Cys12-Thr13-Gly14-Cys15-Leu16-OH
`S
`S
`
`
`The solid lines linking cysteines illustrate disulfide bridges.
`Plecanatide is an amorphous, white to off-white powder. It is soluble in water. TRULANCE tablets are
`supplied as a 3 mg tablet for oral administration. The inactive ingredients are magnesium stearate and
`microcrystalline cellulose.
`12 CLINICAL PHARMACOLOGY
`12.1 Mechanism of Action
`Plecanatide is structurally related to human uroguanylin, and similar to uroguanylin, plecanatide functions as a
`guanylate cyclase-C (GC-C) agonist. Both plecanatide and its active metabolite bind to GC-C and act locally
`on the luminal surface of the intestinal epithelium. Activation of GC-C results in an increase in both
`intracellular and extracellular concentrations of cyclic guanosine monophosphate (cGMP). Elevation of
`intracellular cGMP stimulates secretion of chloride and bicarbonate into the intestinal lumen, mainly through
`activation of the cystic fibrosis transmembrane conductance regulator (CFTR) ion channel, resulting in
`increased intestinal fluid and accelerated transit. In animal models, plecanatide has been shown to increase
`fluid secretion into the gastrointestinal (GI) tract, accelerate intestinal transit, and cause changes in stool
`consistency.
`In an animal model of visceral pain, plecanatide reduced abdominal muscle contractions, a measure of intestinal
`pain. The mechanism has not been studied.
`12.2 Pharmacodynamics
`Food Effect
`Subjects who received either a low-fat, low calorie (LF-LC) meal or a high fat, high calorie (HF-HC) meal
`reported looser stools than fasted subjects up to 24 hours after a single dose of TRULANCE 9 mg (3 times the
`recommended dose). In clinical studies, TRULANCE was administered with or without food [see Dosage and
`Administration (2.2)].
`
`Reference ID: 4044252
`
`6
`
`

`

`
`
`
`12.3 Pharmacokinetics
`Absorption
`Plecanatide is minimally absorbed with negligible systemic availability following oral administration.
`Concentrations of plecanatide and its active metabolite in plasma are below the limit of quantitation after an
`oral TRULANCE dose of 3 mg. Therefore, standard pharmacokinetic parameters such as AUC, maximum
`concentration (Cmax), and half-life (t½) cannot be calculated.
`Food Effect
`In a crossover study, 24 healthy subjects were given a single dose of TRULANCE 9 mg (3 times the
`recommended dose) in 3 different states: fasted; following a low-fat, low-calorie meal (LF-LC; approximately
`350 calories: 17% from fat, 66% from carbohydrate, and 17% from protein); and following a high-fat,
`high-calorie meal (HF-HC; approximately 1000 calories: 60% from fat, 25% from carbohydrate, and 15% from
`protein). Plecanatide was detected in 1 subject (fasted state) at 0.5 and 1 hour post dose. Plecanatide
`concentrations were below the limit of quantitation for all other time points and for all other subjects. The
`active metabolite was not detected in any subject.
`Distribution
`Given that plecanatide concentrations following clinically relevant oral doses are not measurable, plecanatide is
`expected to be minimally distributed in tissues. Oral plecanatide is localized to the GI tract where it exerts its
`effects as a GC-C agonist with negligible systemic exposure. Plecanatide exhibits little to no binding to human
`serum albumin or human α-1-acid glycoprotein.
`Elimination
`Metabolism
`Plecanatide is metabolized in the GI tract to an active metabolite by loss of the terminal leucine moiety. Both
`plecanatide and the metabolite are proteolytically degraded within the intestinal lumen to smaller peptides and
`naturally occurring amino acids.
`Excretion
`No excretion studies have been conducted in humans. Plecanatide and its active metabolite are not measurable
`in plasma following administration of the recommended clinical doses.
`Drug Interaction Studies
`Neither plecanatide nor its active metabolite inhibited the cytochrome P450 (CYP) enzymes 2C9 and 3A4, and
`they did not induce CYP3A4 in vitro.
`Plecanatide and its active metabolite are neither substrates nor inhibitors of the transporters P-glycoprotein
`(P-gp) or breast cancer resistance protein (BCRP) in vitro.
`13 NONCLINICAL TOXICOLOGY
`13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
`Carcinogenesis
`The carcinogenic potential of plecanatide was assessed in 2-year carcinogenicity studies in mice and rats.
`Plecanatide was not tumorigenic in mice at oral doses up to 90 mg/kg/day or in rats at oral doses up to
`100 mg/kg/day. Limited systemic exposure to plecanatide was achieved at the tested dose levels in animals,
`whereas no detectable exposure occurred in humans. Therefore, animal and human doses should not be
`compared directly for evaluating relative exposure.
`
`Reference ID: 4044252
`
`7
`
`

`

`
`
`
`Mutagenesis
`Plecanatide was not genotoxic in the in vitro bacterial reverse mutation (Ames) assay, in vitro mouse lymphoma
`mutation assay, or the in vivo mouse bone marrow micronucleus assay.
`Impairment of Fertility
`Plecanatide had no effect on fertility or reproductive function in male or female mice at oral doses of up to
`600 mg/kg/day.
`14 CLINICAL STUDIES
`The efficacy of TRULANCE for the management of symptoms of CIC was established in two 12-week,
`double-blind, placebo-controlled, randomized, multicenter clinical studies in adult patients (Study 1 and
`Study 2). In the Intention-to-Treat (ITT) population, a total of 905 patients (Study 1) and 870 patients (Study 2)
`were randomized 1:1 to either placebo or TRULANCE 3 mg, once daily. In clinical studies, study medication
`was administered without respect to food intake. Demographics for these studies included an overall mean age
`of 45 years (range 18 to 80 years), 80% female, 72% white, and 24% black.
`To be eligible for the studies, patients were required to meet modified Rome III criteria for at least 3 months
`prior to the screening visit, with symptom onset for at least 6 months prior to diagnosis. Rome III criteria were
`modified to require that patients report less than 3 defecations per week, rarely have a loose stool without the
`use of laxatives, not use manual maneuvers to facilitate defecations, and not meet criteria for IBS-C. In
`addition, patients were required to report at least two of the following symptoms:
`• Straining during at least 25% of defecations
`• Lumpy or hard stool in at least 25% of defecations
`• Sensation of incomplete evacuations for at least 25% of defecations
`• Sensation of anorectal obstruction/blockage for at least 25% of defecations
`Patients who met these criteria were also required to demonstrate the following during the last 2 weeks of the
`screening period:
`• Less than 3 complete spontaneous bowel movements (CSBMs) (a CSBM is an SBM that is associated
`with a sense of complete evacuation) in each of the two weeks
`• Bristol Stool Form Scale (BSFS) of 6 or 7 in less than 25% of spontaneous bowel movements (SBMs)
`(an SBM is a bowel movement occurring in the absence of laxative use)
`• One out of the following three:
`o BSFS of 1 or 2 in at least 25% of defecations
`o A straining value recorded on at least 25% of days when a BM was reported
`o At least 25% of BMs result in a sense of incomplete evacuation
`The efficacy of TRULANCE was assessed using a responder analysis and change-from-baseline in CSBM and
`SBM endpoints. Efficacy was assessed using information provided by patients on a daily basis in an electronic
`diary.
`A responder was defined as a patient who had a least 3 CSBMs in a given week and an increase of at least 1
`CSBM from baseline in the same week for at least 9 weeks out of the 12 week treatment period and at least 3 of
`the last 4 weeks of the study. The responder rates are shown in Table 2.

`# p-value <0.005
`In both studies, improvements in the frequency of CSBMs/week were seen as early as week 1 with
`improvement maintained through week 12. The difference between the TRULANCE group and the placebo
`group in the mean change of CSBMs/week frequency from baseline to week 12 was approximately
`1.1 CSBMs/week.
`Over the 12 week treatment period, improvements were observed in stool frequency (number of CSBMs/week
`and SBMs/week) and/or stool consistency (as measured by the BSFS), and/or in the amount of straining with
`bowel movements (amount of time pushing or physical effort to pass stool) in the TRULANCE group as
`compared to placebo.
`Following completion of the study drug treatment period, patients continued to record data in the daily diary for
`a 2 week Post-Treatment Period. During this time, TRULANCE-treated patients generally returned to baseline
`for these study endpoints.
`In Studies 1 and 2, a third randomized treatment arm of TRULANCE 6 mg once daily did not demonstrate
`additional treatment benefit and had a greater incidence of adverse reactions than TRULANCE 3 mg once daily.
`Therefore, TRULANCE 6 mg once daily is not recommended [see Dosage and Administration (2.1)].
