    INDICATIONS AND USAGE

    WELCHOL is a bile acid sequestrant indicated as an adjunct to diet and exercise to:

    • reduce elevated low-density lipoprotein cholesterol (LDL-C) in adults with primary hyperlipidemia (1.1).
    • reduce LDL-C levels in boys and postmenarchal girls, 10 to 17 years of age, with heterozygous familial hypercholesterolemia (HeFH) (1.1).
    • improve glycemic control in adults with type 2 diabetes mellitus (1.2).

    Limitations of Use (1.3):

    • Do not use for treatment of type 1 diabetes or for diabetic ketoacidosis.
    • The effect on cardiovascular morbidity and mortality has not been determined.
    • Not studied in type 2 diabetes with a dipeptidyl peptidase 4 inhibitor.
    • Not studied in Fredrickson Type I, III, IV, and V dyslipidemias.
    • Not studied in children less than 10 years of age or in pre-menarchal girls.

    DOSAGE AND ADMINISTRATION

    • Obtain lipid parameters, including serum triglyceride (TG) levels and non-HDL C, before starting WELCHOL (2.1)
    • The recommended dosage for adults and children 10 to 17 years old with primary hyperlipidemia is 3.75 grams daily. The recommended dosage for adults with type 2 diabetes mellitus is 3.75 grams daily. WELCHOL should be taken as follows (2.2, 2.4):

    Tablets

    Take 6 tablets once daily or 3 tablets twice daily with a meal and liquid.

    For Oral Suspension

    Take one packet once daily with a meal. To prepare, empty the entire contents of one packet into a glass or cup. Add 1 cup of water, fruit juice, or diet soft drinks. Stir well and drink.

    Chewable Bars

    Take one bar once daily with a meal.

    DOSAGE FORMS AND STRENGTHS

    • Tablets: 625 mg (3)
    • For oral suspension: 3.75 gram packet (3)
    • Chewable Bars: 3.75 gram per bar (3)

    CONTRAINDICATIONS

    • Patients with serum triglyceride levels >500 mg/dL (4).
    • Patients with a history of hypertriglyceridemia-induced pancreatitis (4).
    • Patients with a history of bowel obstruction (4).

    WARNINGS AND PRECAUTIONS

    • Hypertriglyceridemia and Pancreatitis: WELCHOL can increase TG. Hypertriglyceridemia can cause acute pancreatitis. Monitor lipids, including TG and non-high density lipoprotein cholesterol (non-HDL-C). Instruct patients to discontinue WELCHOL and seek prompt medical attention if the symptoms of acute pancreatitis occur (5.1).
    • Gastrointestinal Obstruction: Cases of bowel obstruction have occurred. WELCHOL is not recommended in patients with gastroparesis, other gastrointestinal motility disorders, and in those who have had major gastrointestinal tract surgery and who may be at risk for bowel obstruction (5.2).
    • Vitamin K or Fat-Soluble Vitamin Deficiencies: WELCHOL may decrease absorption of fat-soluble vitamins. Patients with a susceptibility to deficiencies of vitamin K (e.g., patients on warfarin, patients with malabsorption syndromes) or other fat-soluble vitamins may be at increased risk. Patients on oral vitamin supplementation should take their vitamins at least 4 hours prior to WELCHOL (5.3).
    • Drug Interactions: Due to the potential for decreased absorption of other drugs that have not been tested for interaction, consider administering at least 4 hours prior to WELCHOL (5.4, 7, 12.3).
    • Risks in Patients with Phenylketonuria: Phenylalanine can be harmful to patients with phenylketonuria (PKU). WELCHOL for oral suspension contains 27 mg phenylalanine per 3.75 gram packet (5.5, 11).

    ADVERSE REACTIONS

    In clinical trials, the most common (incidence ≥2% and greater than placebo) adverse reactions with WELCHOL included constipation, dyspepsia, and nausea (6.1).

  • 1 INDICATIONS AND USAGE

    1.1 Primary Hyperlipidemia

    WELCHOL is indicated as an adjunct to diet and exercise to reduce elevated low-density lipoprotein cholesterol (LDL-C) in adults with primary hyperlipidemia.

    WELCHOL is indicated to reduce LDL-C levels in boys and postmenarchal girls, 10 to 17 years of age, with heterozygous familial hypercholesterolemia (HeFH) who are unable to reach LDL-C target levels despite an adequate trial of dietary therapy and lifestyle modification.

    1.2 Type 2 Diabetes Mellitus

    WELCHOL is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

    1.3 Limitations of Use

    • WELCHOL should not be used for the treatment of type 1 diabetes or for the treatment of diabetic ketoacidosis.
    • The effect of WELCHOL on cardiovascular morbidity and mortality has not been determined.
    • WELCHOL has not been studied in type 2 diabetes in combination with a dipeptidyl peptidase 4 inhibitor.
    • WELCHOL has not been studied in Fredrickson Type I, III, IV, and V dyslipidemias.

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Testing Prior to Initiation of WELCHOL

    Obtain lipid parameters, including TG levels and non-HDL-C, before starting WELCHOL. WELCHOL is contraindicated in patients with TG levels >500 mg/dL [see Contraindications (4) and Warnings and Precautions (5.1)].

    2.2 Recommended Dosage in Primary Hyperlipidemia and Type 2 Diabetes Mellitus

    The recommended dosage of WELCHOL for adults and children 10 to 17 years old with primary hyperlipidemia is 3.75 grams daily. The recommended dosage of WELCHOL for adults with type 2 diabetes mellitus is 3.75 grams daily. WELCHOL should be taken as follows:

    Tablets

    Take 6 tablets once daily or 3 tablets twice daily. Due to tablet size, WELCHOL for oral suspension is recommended for use in the pediatric population.

    For Oral Suspension

    Take one packet once daily.

    Chewable Bars

    Take one bar once daily.

    2.3 Important Dosing Information for Primary Hyperlipidemia

    WELCHOL can be dosed at the same time as a statin or WELCHOL and the statin can be dosed apart. Monitor lipid levels within 4 to 6 weeks after initiation of WELCHOL.

    2.4 Administration Instructions

    Tablets:

    Take WELCHOL tablets with a meal and liquid. For patients with difficulty swallowing tablets use WELCHOL for oral suspension [see Warnings and Precautions (5.2)].

      • 3.75 gram tan, rectangular, caramel flavored bar
  • 4 CONTRAINDICATIONS

    WELCHOL is contraindicated in patients with:

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Hypertriglyceridemia and Pancreatitis

    WELCHOL, like other bile acid sequestrants, can increase serum TG concentrations. Hypertriglyceridemia can cause acute pancreatitis.

    WELCHOL had effects on serum TG (median increase 5% compared to placebo) in trials of patients with primary hyperlipidemia.

    In trials in patients with type 2 diabetes, greater increases in TG levels occurred when WELCHOL was used as monotherapy (median increase 9.7% compared to placebo) and when WELCHOL was used in combination with pioglitazone (median increase 11% compared to placebo in combination with pioglitazone), sulfonylureas (median increase 18% compared to placebo in combination with sulfonylureas), and insulin (median increase 22% compared to placebo in combination with insulin) [see Adverse Reactions (6.1)].

    Obtain lipid parameters, including TG levels and non-HDL-C, before starting WELCHOL and periodically thereafter. WELCHOL is contraindicated in patients with TG levels >500 mg/dL or patients with a history of hypertriglyceridemia-induced pancreatitis [see Contraindications (4)]. Patients with TG levels greater than 300 mg/dL could have greater increases in serum TG levels with WELCHOL and may require additional TG monitoring. Instruct patients to discontinue WELCHOL and seek prompt medical attention if the symptoms of acute pancreatitis occur (e.g., severe abdominal pain with or without nausea and vomiting). Discontinue WELCHOL if TG levels exceed 500 mg/dL [see Adverse Reactions (6.1)].

    5.2 Gastrointestinal Obstruction

    Postmarketing cases of bowel obstruction have occurred with WELCHOL [see Adverse Reactions (6.2)]. Because of its constipating effects, WELCHOL is not recommended in patients with gastroparesis, other gastrointestinal motility disorders, and in those who have had major gastrointestinal tract surgery and who may be at risk for bowel obstruction. WELCHOL is contraindicated in patients with a history of bowel obstruction [see Contraindications (4)]. Instruct patients to promptly discontinue WELCHOL and seek medical attention if severe abdominal pain or severe constipation occurs.

    Because of the tablet size, WELCHOL tablets can cause dysphagia or esophageal obstruction. For patients with difficulty swallowing tablets use WELCHOL for oral suspension.

    5.3 Vitamin K or Fat-Soluble Vitamin Deficiencies

    WELCHOL may decrease the absorption of fat-soluble vitamins A, D, E, and K. Patients with a susceptibility to deficiencies of vitamin K (e.g., patients on warfarin, patients with malabsorption syndromes) or other fat-soluble vitamins may be at increased risk when taking WELCHOL.

    Patients on oral vitamin supplementation should take their vitamins at least 4 hours prior to WELCHOL [see Drug Interactions (7.1)].

    5.4 Drug Interactions

    WELCHOL reduces gastrointestinal absorption of some drugs. Administer drugs with a known interaction at least 4 hours prior to WELCHOL [see Drug Interactions (7)].

    Due to the potential for decreased absorption of other drugs that have not been tested for interaction, especially those with a narrow therapeutic index, consider administering at least 4 hours prior to WELCHOL [see Clinical Pharmacology (12.3)].

    5.5 Risks in Patients with Phenylketonuria

    Phenylalanine can be harmful to patients with phenylketonuria (PKU). WELCHOL for oral suspension contains phenylalanine, a component of aspartame. Each 3.75 gram packet contains 27 mg of phenylalanine. Before prescribing WELCHOL for oral suspension to a patient with PKU, consider the combined daily amount of phenylalanine from all sources, including WELCHOL for oral suspension.

    5.6 Macrovascular Outcomes

    There have been no clinical studies establishing conclusive evidence of macrovascular disease risk reduction with WELCHOL.

  • 6 ADVERSE REACTIONS

    The following important adverse reactions are described below and elsewhere in the labeling:

    6.1 Clinical Studies Experience

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

    Primary Hyperlipidemia: In 7 double-blind, placebo-controlled, clinical trials, 807 patients with primary hyperlipidemia (age range 18-86 years, 50% women, 90% Caucasians, 7% Blacks, 2% Hispanics, 1% Asians) and elevated LDL-C were treated with WELCHOL 1.5 g/day to 4.5 g/day from 4 to 24 weeks (total exposure 199 patient-years).

    Flu syndrome3.2%3.1%
    Rhinitis3.2%3.1%
    Myalgia2.1%0.4%

    Pediatric Patients 10 to 17 Years of Age: In an 8-week double-blind, placebo-controlled study boys and post-menarchal girls, 10 to 17 years of age, with HeFH (n=192), were treated with WELCHOL tablets (1.9-3.8 g, daily) or placebo tablets.

    Fatigue3.9%1.5%
    Creatine Phosphokinase Increase2.3%0.0%
    Rhinitis2.3%0.0%
    Vomiting2.3%1.5%

    The reported adverse reactions during the additional 18-week open-label treatment period with WELCHOL 3.8 g per day were similar to those during the double-blind period and included headache (7.6%), nasopharyngitis (5.4%), upper respiratory tract infection (4.9%), influenza (3.8%), and nausea (3.8%).

    Type 2 Diabetes Mellitus: In 5 add-on combination and 1 monotherapy double-blind, 12-26 week, placebo-controlled clinical trials in patients with type 2 diabetes mellitus, 1022 patients were treated with WELCHOL. The mean exposure duration was 20 weeks (total exposure 393 patient-years). Patients were to receive 3.8 grams of WELCHOL per day. The mean age of patients was 55.7 years, 52.8 percent of the population was male and 61.9% were Caucasian, 4.8% were Asian, and 15.9% were Black or African American. At baseline the population had a mean HbA1C of 8.2% and 26% had past medical history suggestive of microvascular complications of diabetes.

    Table 3 shows adverse reactions associated with the use of WELCHOL in patients with type 2 diabetes. These adverse reactions were not present at baseline, occurred more commonly on WELCHOL than on placebo, and occurred in at least 2% of patients treated with WELCHOL.

    Table 3 Clinical Studies of WELCHOL for Type 2 Diabetes: Adverse Reactions Reported in ≥ 2% of Patients and More Commonly than in Placebo
    WELCHOL
    N = 1015
    Placebo
    N = 1010
    Constipation6.5%2.2%
    Hypoglycemia3.4%3.1%
    Dyspepsia2.8%1.0%
    Nausea2.6%1.6%
    Hypertension 2.6%1.9%
    Back Pain2.3%1.3%

    A total of 5.3% of WELCHOL-treated patients and 3.6% of placebo-treated patients were discontinued from the diabetes trials due to adverse reactions. This difference was driven mostly by gastrointestinal adverse reactions such as abdominal pain and constipation.

    One patient in the add-on to sulfonylurea trial discontinued due to body rash and mouth blistering that occurred on the first day of dosing of WELCHOL, which may represent a hypersensitivity reaction to WELCHOL.

    Hypertriglyceridemia:

    Patients with fasting serum TG levels above 500 mg/dL were excluded from the diabetes clinical trials. In the diabetes trials, 1292 (67.7%) patients had baseline fasting serum TG levels less than 200 mg/dL, 426 (22.3%) had baseline fasting serum TG levels between 200 and less than 300 mg/dL, 175 (9.2%) had baseline fasting serum TG levels between 300 and 500 mg/dL, and 16 (0.8%) had fasting serum TG levels greater than or equal to 500 mg/dL. The median baseline fasting TG concentration for the study population was 160 mg/dL; the median post-treatment fasting TG was 180 mg/dL in the WELCHOL group and 162 mg/dL in the placebo group. WELCHOL therapy resulted in a median placebo-corrected increase in serum TG of 9.7% (p=0.03) in the monotherapy study and of 5% (p=0.22), 11% (p<0.001), 18% (p<0.001), and 22% (p<0.001), when added to metformin, pioglitazone, sulfonylureas, and insulin, respectively. In comparison, WELCHOL resulted in a median increase in serum TG of 5% compared to placebo (p=0.42) in a 24-week monotherapy lipid-lowering trial.

    Fasting TG concentrations ≥500 mg/dL occurred in 0.9% of WELCHOL-treated patients compared to 0.7% of placebo-treated patients in the diabetes trials. Among these patients, the TG concentrations with WELCHOL (median 606 mg/dL; interquartile range 570-794 mg/dL) were similar to that observed with placebo (median 663 mg/dL; interquartile range 542-984 mg/dL). Five (0.6%) patients on WELCHOL and 3 (0.3%) patients on placebo developed TG elevations ≥1000 mg/dL.

    Cardiovascular adverse reactions:

    During the diabetes trials, the incidence of patients with serious adverse reactions involving the cardiovascular system was 2.2% (22/1015)) in the WELCHOL group and 1% (10/1010) in the placebo group. These overall rates included disparate events (e.g., myocardial infarction, aortic stenosis, and bradycardia); therefore, the significance of this imbalance is unknown.

    6.2 Post-marketing Experience

    The following additional adverse reactions have been identified during post-approval use of WELCHOL. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

    Adverse Reactions Resulting from Drug Interactions [see Drug Interactions (7)]:

    • Increased seizure activity or decreased phenytoin levels in patients receiving phenytoin.
    • Reduced International Normalized Ratio (INR) in patients receiving warfarin therapy.
    • Elevated thyroid-stimulating hormone (TSH) in patients receiving thyroid hormone replacement therapy.

    Gastrointestinal:

    Bowel obstruction (in patients with a history of bowel obstruction or resection), dysphagia or esophageal obstruction (occasionally requiring medical intervention), fecal impaction, pancreatitis, abdominal distension, exacerbation of hemorrhoids, and increased transaminases.

    Laboratory Abnormalities:

    Hypertriglyceridemia

  • 7 DRUG INTERACTIONS

    7.1 WELCHOL Drug Interactions that Decrease the Exposure of the Concomitant Medication

    Table 4 includes a list of drugs that decrease exposure of the concomitant medication when administered concomitantly with WELCHOL and instructions for preventing or managing them.

    Table 4 WELCHOL Drug Interactions that Decrease the Exposure of the Concomitant Medication

    Intervention:Monitor patients glycemic control.
  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    WELCHOL is not absorbed systemically following oral administration, and maternal use is not expected to result in fetal exposure to the drug. Limited available data on the use of WELCHOL are insufficient to determine a drug-associated risk of major congenital malformations or miscarriage. In animal reproduction studies, no evidence of either maternal or fetal toxicity was found in rats or rabbits exposed to colesevelam hydrochloride during the period of fetal organogenesis at 5 and 8 times, respectively, the maximum recommended human dose (MRHD) of 3.75 g/day, based on body surface area (mg/m2). No adverse effects on offspring survival and development were observed in rats administered 5 times the MRHD (see Data). WELCHOL may decrease the absorption of fat-soluble vitamins [see Warnings and Precautions (5.3)]. There are no data available on the effect of colesevelam hydrochloride on the absorption of fat-soluble vitamins in pregnant women. If the patient becomes pregnant while taking WELCHOL, the patient should be advised of the lack of known clinical benefit with continued use during pregnancy.

    The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the US 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

    Human Data

    There are no adequate and well-controlled studies of colesevelam hydrochloride use in pregnant women. In the postmarketing setting there have been infrequent reports of pregnancy with use of WELCHOL and a causal association with congenital anomalies has not been established.

    Animal Data

    In pregnant rats given dietary doses of 0.3, 1.0, 3.0 g/kg/day colesevelam hydrochloride from gestation days 7 through 17, no teratogenic effects were observed. Exposures at 3.0 g/kg/day were 8 times the human exposure at 3.75 g/day MRHD, based on body surface area (mg/m2).

    In pregnant rabbits given an oral gavage doses of 0.1, 0.5, 1.0 g/kg/day colesevelam hydrochloride from gestation days 6 through 18, no teratogenic effects were observed. Exposures at 1.0 g/kg/day were 5 times the human exposure at 3.75 g/day MRHD, based on body surface area (mg/m2).

    In pregnant rats given oral gavage doses of 0.1, 0.3, 1.0 g/kg/day colesevelam hydrochloride from gestation day 6 through lactation day 21 (weaning), no adverse effects on survival and development were observed. Exposures at 1.0 g/kg/day were 5 times the human exposure at 3.75 g/day MRHD, based on body surface area (mg/m2).

    8.2 Lactation

    Risk Summary

    WELCHOL is not absorbed systemically by the mother following oral administration, and breastfeeding is not expected to result in exposure of the child to WELCHOL.

    8.3 Females and Males of Reproductive Potential

    Contraception

    Use of WELCHOL may reduce the efficacy of oral contraceptives. Advise patients to take oral contraceptives at least 4 hours prior to taking WELCHOL [see Drug Interactions (7)].

    8.4 Pediatric Use

    The safety and effectiveness of WELCHOL as monotherapy or in combination with a statin were evaluated in children, 10 to 17 years of age with HeFH [see Clinical Studies (14.1)]. The adverse reaction profile was similar to that of patients treated with placebo. In this limited controlled study, there were no significant effects on growth, sexual maturation, fat-soluble vitamin levels or clotting factors in the adolescent boys or girls relative to placebo [see Adverse Reactions (6.1)].

    Due to tablet size, WELCHOL for oral suspension is recommended for use in the pediatric population. Dose adjustments are not required when WELCHOL is administered to children 10 to 17 years of age.

    WELCHOL has not been studied in children younger than 10 years of age or in pre-menarchal girls.

    8.5 Geriatric Use

    Primary Hyperlipidemia: Of the 1350 patients enrolled in the hyperlipidemia clinical studies, 349 (26%) were ≥65 years old, and 58 (4%) were ≥75 years old. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

    Type 2 Diabetes Mellitus: Of the 2048 patients enrolled in the six diabetes studies, 397 (19%) were ≥65 years old, and 36 (2%) were ≥75 years old. In these trials, WELCHOL 3.8 g/day or placebo was added onto background anti-diabetic therapy. No overall differences in safety or effectiveness were observed between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

    8.6 Renal Impairment

    Type 2 Diabetes Mellitus: Of the 2048 patients enrolled in the six diabetes studies, 807 (39%) had mild renal insufficiency (creatinine clearance [CrCl] 50-<80 mL/min), 61 (3%) had moderate renal insufficiency (CrCl 30-<50 mL/min), and none had severe renal insufficiency (CrCl <30 mL/min), as estimated from baseline serum creatinine using the Modification of Diet in Renal Disease (MDRD) equation. No overall differences in safety or effectiveness were observed between patients with CrCl <50 mL/min (n=53) and those with a CrCl ≥50 mL/min (n=1075) in the add-on to metformin, sulfonylureas, and insulin diabetes studies. In the monotherapy study and add-on to pioglitazone study only 3 and 5 patients respectively had moderate renal insufficiency.

  • 10 OVERDOSAGE

    WELCHOL is not absorbed and the risk of systemic toxicity is low. Excessive doses of WELCHOL may cause more severe local gastrointestinal effects (e.g., constipation).

  • 11 DESCRIPTION

    WELCHOL (colesevelam hydrochloride) is a non-absorbed, polymeric, lipid-lowering and glucose-lowering agent for oral administration. Colesevelam hydrochloride is a high-capacity bile acid-binding molecule.

    Colesevelam hydrochloride is poly(allylamine hydrochloride) cross-linked with epichlorohydrin and alkylated with 1-bromodecane and (6-bromohexyl)-trimethylammonium bromide. The chemical name (IUPAC) of colesevelam hydrochloride is allylamine polymer with 1-chloro-2,3-epoxypropane, [6-(allylamino)-hexyl]trimethylammonium chloride and N-allyldecylamine, hydrochloride. The chemical structure of colesevelam hydrochloride is represented by the following formula:

    Chemical Structure

    wherein (a) represents allyl amine monomer units that have not been alkylated by either of the 1-bromodecane or (6-bromohexyl)-trimethylammonium bromide alkylating agents or cross-linked by epichlorohydrin; (b) represents allyl amine units that have undergone cross-linking with epichlorohydrin; (c) represents allyl amine units that have been alkylated with a decyl group; (d) represents allyl amine units that have been alkylated with a (6-trimethylammonium) hexyl group, and m represents a number ≥ 100 to indicate an extended polymer network. A small amount of the amines are dialkylated, and are not depicted in the formula above. No regular order of the groups is implied by the structure; cross-linking and alkylation are expected to occur randomly along the polymer chains. A large amount of the amines are protonated. The polymer is depicted in the hydrochloride form; a small amount of the halides are bromide. Colesevelam hydrochloride is hydrophilic and insoluble in water.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Primary Hyperlipidemia: Colesevelam hydrochloride, the active pharmaceutical ingredient in WELCHOL, is a non-absorbed, lipid-lowering polymer that binds bile acids in the intestine, impeding their reabsorption. As the bile acid pool becomes depleted, the hepatic enzyme, cholesterol 7-α-hydroxylase, is upregulated, which increases the conversion of cholesterol to bile acids. This causes an increased demand for cholesterol in the liver cells, resulting in the dual effect of increasing transcription and activity of the cholesterol biosynthetic enzyme, HMG-CoA reductase, and increasing the number of hepatic LDL receptors. These compensatory effects result in increased clearance of LDL-C from the blood, resulting in decreased serum LDL-C levels. Serum TG levels may increase or remain unchanged.

    Type 2 Diabetes Mellitus: The mechanism by which WELCHOL improves glycemic control is unknown.

    12.2 Pharmacodynamics

    A maximum therapeutic response to the lipid-lowering effects of WELCHOL was achieved within 2 weeks and was maintained during long-term therapy. In the diabetes clinical studies, a therapeutic response to WELCHOL, as reflected by a reduction in hemoglobin A1C (A1C), was initially noted following 4-6 weeks of treatment and reached maximal or near-maximal effect after 12-18 weeks of treatment.

    12.3 Pharmacokinetics

    Absorption: Colesevelam hydrochloride is a hydrophilic, water-insoluble polymer that is not hydrolyzed by digestive enzymes and is not absorbed.

    Distribution: Colesevelam hydrochloride is not absorbed, and therefore, its distribution is limited to the gastrointestinal tract.

    Metabolism: Colesevelam hydrochloride is not metabolized systemically and does not interfere with systemic drug-metabolizing enzymes such as cytochrome P-450.

    Excretion: In 16 healthy volunteers, an average of 0.05% of administered radioactivity from a single 14C-labeled colesevelam hydrochloride dose was excreted in the urine.

    Drug Interactions: Drug interactions between colesevelam and concomitantly administered drugs were screened through in vitro studies and confirmed in in vivo studies. In vitro studies demonstrated that cephalexin, metformin, and ciprofloxacin had negligible binding to colesevelam hydrochloride. Therefore, an in vivo pharmacokinetic interaction of WELCHOL with these drugs is unlikely. WELCHOL was found to have no significant effect on the bioavailability of aspirin, atenolol, digoxin, enalapril, fenofibrate, lovastatin, metoprolol, phenytoin, pioglitazone, quinidine, rosiglitazone, sitagliptin, valproic acid, and warfarin. The results of additional in vivo drug interactions of WELCHOL are presented in Table 6.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis: A 104-week carcinogenicity study with colesevelam hydrochloride was conducted in CD-1 mice, at oral dietary doses up to 3 g/kg/day. This dose was approximately 50 times the maximum recommended human dose of 4.5 g/day, based on body weight, mg/kg. There were no significant drug-induced tumor findings in male or female mice. In a 104-week carcinogenicity study with colesevelam hydrochloride in Harlan Sprague-Dawley rats, a statistically significant increase in the incidence of pancreatic acinar cell adenoma was seen in male rats at doses >1.2 g/kg/day (approximately 20 times the maximum human dose, based on body weight, mg/kg) (trend test only). A statistically significant increase in thyroid C-cell adenoma was seen in female rats at 2.4 g/kg/day (approximately 40 times the maximum human dose, based on body weight, mg/kg).

    Mutagenesis: Colesevelam hydrochloride and 4 degradants present in the drug substance have been evaluated for mutagenicity in the Ames test and a mammalian chromosomal aberration test. The 4 degradants and an extract of the parent compound did not exhibit genetic toxicity in an in vitro bacterial mutagenesis assay in S. typhimurium and E. coli (Ames assay) with or without rat liver metabolic activation. An extract of the parent compound was positive in the Chinese Hamster Ovary (CHO) cell chromosomal aberration assay in the presence of metabolic activation and negative in the absence of metabolic activation. The results of the CHO cell chromosomal aberration assay with 2 of the 4 degradants, decylamine HCl and aminohexyltrimethyl ammonium chloride HCl, were equivocal in the absence of metabolic activation and negative in the presence of metabolic activation. The other 2 degradants, didecylamine HCl and 6-decylamino-hexyltrimethyl ammonium chloride HCl, were negative in the presence and absence of metabolic activation.

    Impairment of Fertility: Colesevelam hydrochloride did not impair fertility in rats at doses up to 3 g/kg/day (approximately 50 times the maximum human dose, based on body weight, mg/kg).

    13.2 Animal Toxicology and/or Pharmacology

    Reproductive Toxicology Studies

    Reproduction studies have been performed in rats and rabbits at doses up to 3 g/kg/day and 1 g/kg/day, respectively (approximately 50 and 17 times the maximum human dose, based on body weight, mg/kg) and have revealed no evidence of harm to the fetus due to colesevelam hydrochloride.

  • 14 CLINICAL STUDIES

    14.1 Primary Hyperlipidemia

    WELCHOL reduces TC, LDL-C, apolipoprotein B (Apo B), and non-HDL-C when administered alone or in combination with a statin in patients with primary hyperlipidemia.

    Approximately 1600 patients were studied in 9 clinical trials with treatment durations ranging from 4 to 50 weeks. With the exception of one open-label, uncontrolled, long-term extension study, all studies were multicenter, randomized, double-blind, and placebo-controlled. A maximum therapeutic response to WELCHOL was achieved within 2 weeks and was maintained during long-term therapy.

    Monotherapy: In a study in patients with LDL-C between 130 mg/dL and 220 mg/dL (mean 158 mg/dL), WELCHOL was given for 24 weeks in divided doses with the morning and evening meals.

    As shown in Table 7, the mean LDL-C reductions were 15% and 18% at the 3.8 g and 4.5 g doses. The respective mean TC reductions were 7% and 10%. The mean Apo B reductions were 12% in both treatment groups. WELCHOL at both doses increased HDL-C by 3%. Increases in TG of 9-10% were observed at both WELCHOL doses but the changes were not statistically different from placebo.

    In a study in 98 patients with LDL-C between 145 mg/dL and 250 mg/dL (mean 169 mg/dL), WELCHOL 3.8 g was given for 6 weeks as a single dose with breakfast, as a single dose with dinner, or as divided doses with breakfast and dinner. The mean LDL-C reductions were 18%, 15%, and 18% for the 3 dosing regimens, respectively. The reductions with these 3 regimens were not statistically different from one another.

    Combination Therapy: Co-administration of WELCHOL and a statin (atorvastatin, lovastatin, or simvastatin) in 3 clinical studies demonstrated an additive reduction of LDL-C. The mean baseline LDL-C was 184 mg/dL in the atorvastatin study (range 156-236 mg/dL), 171 mg/dL in the lovastatin study (range 115-247 mg/dL), and 188 mg/dL in the simvastatin study (range 148-352 mg/dL). As demonstrated in Table 8, WELCHOL doses of 2.3 g to 3.8 g resulted in an additional 8% to 16% reduction in LDL-C above that seen with the statin alone.

    In all 3 studies, the LDL-C reduction achieved with the combination of WELCHOL and any given dose of statin therapy was statistically superior to that achieved with WELCHOL or that dose of the statin alone. The LDL-C reduction with atorvastatin 80 mg was not statistically significantly different from the combination of WELCHOL 3.8 g and atorvastatin 10 mg.

    Pediatric Therapy: The safety and efficacy of WELCHOL in pediatric patients were evaluated in an 8-week, multi-center, randomized, double-blind, placebo-controlled, parallel-group study followed by an open-label phase, in 194 boys and postmenarchal girls 10-17 years of age (mean age 14.1 years) with HeFH, taking a stable dose of an FDA-approved statin (with LDL-C >130 mg/dL) or naïve to lipid-lowering therapy (with LDL-C >160 mg/dL). This study had 3 periods: a single-blind, placebo stabilization period; an 8-week, randomized, double-blind, parallel-group, placebo-controlled treatment period; and an 18-week, open-label treatment period. Forty-seven (24%) patients were taking statins and 147 (76%) patients were statin-naïve at screening. The mean baseline LDL-C at Day 1 was approximately 199 mg/dL.

    During the double-blind treatment period, patients were assigned randomly to treatment: WELCHOL 3.8 g/day (n=64), WELCHOL 1.9 g/day (n=65), or placebo (n=65). In total, 186 patients completed the double-blind treatment period. After 8 weeks of treatment, WELCHOL 3.8 g/day significantly decreased plasma levels of LDL-C, non-HDL-C, TC, and Apo B and significantly increased HDL-C. A moderate, non-statistically significant increase in TG was observed versus placebo (Table 9).

    During the open-label treatment period patients were treated with WELCHOL 3.8 g/day. In total, 173 (89%) patients completed 26 weeks of treatment. Results at Week 26 were consistent with those at Week 8.

    14.2 Type 2 Diabetes Mellitus

    WELCHOL has been studied as monotherapy and in combination with metformin, pioglitazone, sulfonylureas, and insulin. In these studies, WELCHOL and placebo were administered either as 3 tablets twice daily with lunch and dinner or as 6 tablets with dinner alone.

    Monotherapy: The efficacy of WELCHOL 3.8 g/day as anti-diabetes monotherapy was evaluated in a randomized double-blind, placebo-controlled trial involving 357 patients (176 WELCHOL and 181 placebo) with T2DM who were treatment-naïve or had not received antihyperglycemic medication within 3 months prior to the start of the study. Statin use at baseline was reported in 13% of the WELCHOL-treated patients and 16% of the placebo-treated patients.

    WELCHOL resulted in a statistically significant reduction in A1C of 0.27% compared to placebo (Table 10).

    The mean baseline LDL-C was 121 mg/dL in the monotherapy trial. WELCHOL treatment resulted in a placebo-corrected 11% reduction in LDL-C. WELCHOL treatment also reduced serum TC, ApoB, and non-HDL-C (Table 11). The mean change in body weight was -0.6 kg for WELCHOL and -0.7 kg for placebo treatment groups.

    Placebo1601.81.20.9-0.13.05.8

    Add-on Combination Therapy: The efficacy of WELCHOL 3.8 g/day in patients with type 2 diabetes mellitus was evaluated in 5 double-blind, placebo-controlled add-on therapy trials involving a total of 1691 patients with baseline A1C 7.5-9.5%. Patients were enrolled and maintained on their pre-existing, stable, background anti-diabetic regimen. Statin use at baseline was reported in 41% of the WELCHOL-treated patients and 48% of the placebo-treated patients.

    In 3 add-on combination therapy trials (metformin, sulfonylurea and insulin), treatment with WELCHOL resulted in a statistically significant reduction in A1C of 0.5% compared to placebo. Similar placebo-corrected reductions in A1C occurred in patients who received WELCHOL in combination with metformin, sulfonylurea, or insulin monotherapy or combinations of these therapies with other anti-diabetic agents. In the pioglitazone trial, treatment with WELCHOL resulted in a statistically significant reduction in A1C of 0.32% compared to placebo. In the metformin, pioglitazone, and sulfonylurea trials, treatment with WELCHOL also resulted in statistically significant reductions in fasting plasma glucose (FPG) of at least 14 mg/dL compared to placebo.

    WELCHOL had consistent effects on A1C across subgroups of age, gender, race, body mass index, and baseline A1C. WELCHOL's effects on A1C were also similar for the two dosing regimens (3 tablets with lunch and with dinner or 6 tablets with dinner alone).

    The mean baseline LDL-C was 104 mg/dL in the metformin study (range 32-214 mg/dL), 107 mg/dL in the pioglitazone study (range 48-263 mg/dL), 106 mg/dL in the sulfonylurea study (range 41-264 mg/dL), 102 mg/dL in the insulin study (range 35-204 mg/dL). In these trials, WELCHOL treatment was associated with a 12% to 16% reduction in LDL-C levels. The percentage decreases in LDL-C were of similar magnitude to those observed in patients with primary hyperlipidemia. WELCHOL treatment was associated with statistically significant increases in TG levels in the studies of patients on insulin, patients on a sulfonylurea, and patients on pioglitazone but not in the study of patients on metformin. The clinical significance of these increases is unknown. WELCHOL is contraindicated in patients with TG levels > 500 mg/dL [see Contraindications (4)] and periodic monitoring of lipid parameters including TG and non-HDL-C levels is recommended [see Warnings and Precautions (5.2) and Adverse Reactions (6.1)].

    Body weight did not significantly increase from baseline with WELCHOL therapy, compared with placebo, in any of the add-on combination diabetes studies.

    Add-on Combination Therapy with Metformin: WELCHOL 3.8 g/day or placebo was added to background anti-diabetic therapy in a 26-week trial of 316 patients already receiving treatment with metformin alone (N=159) or metformin in combination with other oral agents (N=157). A total of 60% of these patients were receiving ≥1,500 mg/day of metformin. In combination with metformin, WELCHOL resulted in statistically significant placebo-corrected reductions in A1C and FPG (Table 12). WELCHOL also reduced TC, LDL-C, Apo B, and non-HDL-C (Table 13). The mean percent change in serum LDL-C levels with WELCHOL compared to placebo was -16% among statin users and statin non-users; the median percent change in serum TG levels with WELCHOL compared to placebo was -2% among statin users and 10% among statin non-users. The mean change in body weight was -0.5 kg for WELCHOL and -0.3 kg for placebo.

    Add-on Combination Therapy with pioglitazone: WELCHOL 3.8 g/day or placebo was added to background anti-diabetic therapy in a 24-week trial of 562 patients already receiving treatment with pioglitazone alone (N=51) or pioglitazone in combination with other oral agents (N=511). Of these, most were on dual therapy with metformin (N=298) or triple therapy with metformin and a sulfonylurea (N=139). In combination with pioglitazone-based therapy, WELCHOL resulted in statistically significant reductions in A1C and FPG compared to placebo (Table 14). WELCHOL also reduced TC, LDL-C, Apo B, and non-HDL-C but increased serum TG (Table 15). The mean change in body weight was 0.8 kg for WELCHOL and 0.4 kg for placebo.

    Add-on Combination Therapy with Sulfonylurea: WELCHOL 3.8 g/day or placebo was added to background anti-diabetic therapy in a 26-week trial of 460 patients already treated with sulfonylurea alone (N=156) or sulfonylurea in combination with other oral agents (N=304). A total of 72% of these patients were receiving at least half-maximal doses of sulfonylurea therapy. In combination with a sulfonylurea, WELCHOL resulted in statistically significant placebo-corrected reductions in A1C and FPG (Table 16). WELCHOL also reduced TC, LDL-C, Apo B, and non-HDL-C, but increased serum TG (Table 17). The mean percent change in serum LDL-C levels with WELCHOL compared to placebo was -18% among statin users and -15% among statin non-users; the median percent increase in serum TG with WELCHOL compared to placebo was 29% among statin users and 9% among statin non-users. The mean change in body weight was 0.0 kg for WELCHOL and -0.4 kg for placebo.

    Add-on Combination Therapy with Insulin: WELCHOL 3.8 g/day or placebo was added to background anti-diabetic therapy in a 16-week trial of 287 patients already treated with insulin alone (N=116) or insulin in combination with oral agents (N=171). At baseline, the median daily insulin dose was 70 units in the WELCHOL group and 65 units in the placebo group. In combination with insulin, WELCHOL resulted in a statistically significant placebo-corrected reduction in A1C (Table 18). WELCHOL also reduced LDL-C and Apo B, but increased serum TG (Table 19). The mean percent change in serum LDL-C levels with WELCHOL compared to placebo was -13% among statin users and statin non-users; the median percent increase in serum TG levels with WELCHOL compared to placebo was 24% among statin users and 17% among statin non-users. The mean change in body weight was 0.6 kg for WELCHOL and 0.2 kg for placebo.
