Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following serious or otherwise important adverse reactions for bowel preparations are described elsewhere in the labeling: Serious Fluid and Electrolyte Abnormalities [see Warnings and Precautions (5.1) ] Seizures [see Warnings and Precautions (5.2) ] Use in Patients with Renal Impairment [see Warnings and Precautions (5.3) ] Cardiac Arrhythmias [see Warnings and Precautions (5.4) ] Syncope [see Warnings and Precautions (5.5) ] Colonic Mucosal Ulceration, Ischemic Colitis and Ulcerative Colitis [see Warnings and Precautions (5.6) ] Use in Patients with Significant Gastrointestinal Disease [see Warnings and Precautions (5.7) ] Aspiration [see Warnings and Precautions (5.8) ] Most common adverse reactions are: Adults (≥2%): nausea, headache, hypermagnesemia, abdominal pain and dehydration or dizziness. ( 6.1 ) Pediatrics 9 to 16 years (>5%): nausea, vomiting, and abdominal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Ferring Pharmaceuticals Inc. at 1-888-FERRING (1-888-337-7464) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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 clinical trials of another drug and may not reflect the rates observed in practice. Adults Clinical Study of CLENPIQ - Study 1 Table 1 displays the most common adverse reactions in a randomized, multicenter, assessor-blinded, non-inferiority trial of CLENPIQ for colon cleansing in adults (Study 1). CLENPIQ was compared to another oral sodium picosulfate, magnesium oxide, and anhydrous citric acid product, both administered according to the Split-Dose dosage regimen [see Clinical Studies (14) ] .

In this study the protocol specified that abdominal bloating, distention, pain/cramping, and watery diarrhea, which are known to occur in response to bowel preparation, were documented as adverse events only if they required medical intervention (such as a change in study drug or led to discontinuation, therapeutic or diagnostic procedures, met the criteria for serious adverse event) or showed clinically significant worsening during the study that was not in the frame of the usual clinical course, as determined by the investigator. The most common adverse reactions in Study 2 are shown in Table 2.

Drug Interactions

7 DRUG INTERACTIONS Drugs that increase risks due to fluid and electrolyte changes. ( 7.1 ) 7.1 Drugs That May Increase Risks of Fluid and Electrolyte Abnormalities Use caution when prescribing CLENPIQ for patients with conditions or who are taking other drugs, that increase the risk for fluid and electrolyte disturbances or may increase the risk of renal impairment, seizures, syncope, arrhythmias or QT prolongation in the setting of fluid and electrolyte abnormalities [see Warnings and Precautions (5.1 , 5.2 , 5.3 , 5.4 , 5.5) ] . 7.2 Potential for Reduced Drug Absorption CLENPIQ can reduce the absorption of other co-administered drugs [see Dosage and Administration (2.1) ] : Administer oral medications at least one hour before of the start of administration of CLENPIQ. Administer tetracycline and fluoroquinolone antibiotics [see Drug Interactions (7.3) ] , iron, digoxin, chlorpromazine, and penicillamine at least 2 hours before and not less than 6 hours after administration of CLENPIQ to avoid chelation with magnesium. 7.3 Antibiotics Prior or concomitant use of antibiotics with CLENPIQ may reduce efficacy of CLENPIQ as conversion of sodium picosulfate to its active metabolite BHPM is mediated by colonic bacteria.

Contraindications

4 CONTRAINDICATIONS CLENPIQ is contraindicated in the following conditions: Patients with severe renal impairment (creatinine clearance less than 30 mL/minute), which may result in accumulation of magnesium [see Warnings and Precautions (5.3) ]. Gastrointestinal obstruction or ileus [see Warnings and Precautions (5.6) ]. Bowel perforation [see Warnings and Precautions (5.6) ]. Toxic colitis or toxic megacolon. Gastric retention. Hypersensitivity to any of the ingredients in CLENPIQ [see Adverse Reactions (6.2) ]. Severe renal impairment (creatinine clearance less than 30 mL/minute) ( 4 , 5.3 , 8.6 ) Gastrointestinal (GI) obstruction or ileus ( 4 ) Bowel perforation ( 4 ) Toxic colitis or toxic megacolon ( 4 ) Gastric retention ( 4 ) Hypersensitivity to any of the ingredients in CLENPIQ ( 4 )

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary There are no data with CLENPIQ use in pregnant women to determine a drug-associated risk of adverse developmental outcomes. In animal reproduction studies, no adverse developmental effects were observed in pregnant rats when sodium picosulfate, magnesium oxide, and anhydrous citric acid were administered orally at doses 1.2 times the recommended human dose based on body surface area during organogenesis. 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 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 Reproduction studies with sodium picosulfate, magnesium oxide, and anhydrous citric acid have been performed in pregnant rats following oral administration of up to 2000 mg/kg twice daily (about 1.2 times the recommended human dose based on body surface area) during the period of organogenesis. There was no evidence of harm to the fetus due to sodium picosulfate, magnesium oxide, and anhydrous citric acid. The reproduction study in rabbits was not adequate, as treatment-related mortalities were observed at all doses. A pre and postnatal development study with sodium picosulfate, magnesium oxide, and anhydrous citric acid in rats showed no evidence of any adverse effect on pre and postnatal development at oral doses up to 2000 mg/kg twice daily (about 1.2 times the recommended human dose based on body surface area). Published reproduction studies with sodium picosulfate in pregnant rats and rabbits during the period of organogenesis did not show evidence of harm to the fetus at doses up to 100 mg/kg (approximately 49 and 98 times, respectively, the recommended human dose of 10 mg sodium picosulfate based on body surface area).

Overdosage

10 OVERDOSAGE Overdosage of more than the recommended dose of CLENPIQ may lead to severe electrolyte disturbances, as well as dehydration and hypovolemia, with signs and symptoms of these disturbances [see Warnings and Precautions (5.1) ] . Monitor for fluid and electrolyte disturbances and treat symptomatically.
