PARSIPPANY, N.J., Oct. 7 /PRNewswire/ -- Daiichi Sankyo, Inc. (DSI) announced today that the U.S. Food and Drug Administration (FDA) has approved the supplemental new drug application (sNDA) for Welchol(R) (colesevelam HCl) to be used as an adjunct to diet and exercise for the reduction of elevated low-density lipoprotein cholesterol (LDL-C) in boys and postmenarchal girls, 10 to 17 years of age, with heterozygous familial hypercholesterolemia (heFH) alone or in combination with a statin after failing an adequate trial of diet therapy. Originally approved in 2000 for LDL-C lowering and in 2008 for A1C reduction in adults, Welchol is approved as an adjunct to diet and exercise to reduce elevated LDL-C in adults with primary hyperlipidemia and improve glycemic control in adults with type 2 diabetes mellitus.
Familial hypercholesterolemia (FH) is a genetic disorder resulting in elevated LDL cholesterol and increased risk of cardiovascular disease (CVD).(1) There are 10 million people with FH worldwide, the majority of whom have heFH.(2)
“The FDA approval of Welchol for children with inherited high cholesterol provides another important treatment option for these children, whose elevated LDL cholesterol puts them at increased risk for cardiovascular disease*,"( )said Evan A. Stein, MD, PhD, Director, Metabolic & Atherosclerosis Research Center, Cincinnati, OH. “The pivotal trial of Welchol in this pediatric patient population demonstrated that Welchol, as monotherapy or when combined with a statin, significantly reduced LDL-C.”
The approval of Welchol for pediatric patients with heFH is based on data from an eight-week, multi-center, randomized, placebo-controlled clinical study, which evaluated the efficacy of Welchol tablets (1.875 or 3.75 g/d) as monotherapy or in combination with a statin. The study was conducted with boys and postmenarchal girls 10-17 years of age, who were either treatment naive or on stable background statin therapy.( )The most commonly reported adverse reactions reported in >/= 2 percent of patients -- and more commonly than those given placebo -- were nasopharyngitis, headache, fatigue, creatine phosphokinase increase, rhinitis and vomiting.

Welchol for Oral Suspension
The FDA also approved Welchol(R) (colesevelam HCl) for Oral Suspension, providing an alternative to the current tablet formulation. Welchol for Oral Suspension is indicated as an adjunct to diet and exercise to improve both glycemic control in adults with type 2 diabetes mellitus, and to reduce elevated LDL cholesterol in adults with primary hyperlipidemia (Fredrickson Type IIa) as monotherapy or in combination with a hydroxymethyl-glutaryl-coenzyme A (HMG CoA) reductase inhibitor (a statin). Welchol for Oral Suspension is also indicated for use as an adjunct to diet and exercise for the reduction of elevated LDL-C in boys and post-menarchal girls, 10 to 17 years of age, with heFH alone or in combination with a statin after failing an adequate trial of diet therapy. The recommended dose of Welchol for Oral Suspension is one 3.75 gram packet once daily.

Important Limitations of Use
Contraindications
Welchol is contraindicated in individuals with bowel obstruction, those with serum triglyceride (TG) concentrations of >500 mg/dL, or with a history of hypertriglyceridemia-induced pancreatitis.
Warnings and Precautions
The effect of Welchol on cardiovascular morbidity and mortality has not been determined.
Welchol can increase serum TG concentrations particularly when used in combination with sulfonylureas or insulin. Caution should be exercised when treating patients with TG levels >300 mg/dL.
Welchol may decrease the absorption of fat-soluble vitamins A, D, E and K. Patients on vitamin supplements should take their vitamins at least 4 hours prior to Welchol. Caution should be exercised when treating patients with a susceptibility to vitamin K or fat-soluble vitamin deficiencies.
Caution should also be exercised when treating patients with gastroparesis, gastrointestinal motility disorders, major gastrointestinal tract surgery, and when treating patients with dysphagia and swallowing disorders.
Welchol reduces gastrointestinal absorption of some drugs. Drugs with a known interaction with colesevelam, especially those with a narrow therapeutic index, should also be administered at least 4 hours prior to Welchol. Drugs that have not been tested for interaction with colesevelam, especially those with a narrow therapeutic index, should also be administered at least 4 hours prior to Welchol. Alternatively, the physician should monitor drug levels of the coadministered drug.
To avoid esophageal distress, Welchol for Oral Suspension should not be taken in its dry form.
Due to tablet size, Welchol for Oral Suspension is recommended for, but not limited to, use in the pediatric population as well as in any patient who has difficulty swallowing tablets.
Phenylketonurics: Welchol for Oral Suspension contains 48 mg phenylalanine per 3.75 gram dose.
Adverse Reactions
In clinical trials, the adverse reactions observed in >=2% of patients, and more commonly with Welchol than placebo, regardless of investigator assessment of causality seen in:
Post-marketing experience: Due to the voluntary nature of these reports it is not possible to reliably estimate frequency or establish a causal relationship.
Pregnancy
