Outcome Measures

Primary Outcomes (1)

  • To evaluate the effect of 8 weeks treatment with WelChol on insulin sensitivity,as measured by the hyperinsulinemic-euglycemic clamp method, i.e., placebo-corrected change from baseline in M-value.

    8 weeks

Secondary Outcomes (3)

  • To evaluate the effect of 2 weeks treatment with WelChol on insulin sensitivity,as measured by the hyperinsulinemic-euglycemic clamp method.

    2 weeks

  • To evaluate acute and chronic effects of treatment with WelChol on plasma glucose after ingestion of a standard meal replacement.

    8 weeks

  • To evaluate the effect of treatment with WelChol on HbA1C, insulin, fasting plasma glucose, and fructosamine.

You may qualify if:

  • Subjects meeting the following criteria at the Screening Visit will be eligible to participate in the trial:
  • Have given written informed consent
  • Ages 18 to 75 years, inclusive
  • Diagnosis of type 2 diabetes mellitus of at least 3 months duration
  • HbA1C 7.0- 10.0%, inclusive
  • Antidiabetic treatment may include oral agents; all antidiabetic agents must be withdrawn before randomization
  • Women may be enrolled if they are not pregnant (negative serum βHCG at the Screening Visit), are not breast-feeding, and do not plan to become pregnant during the trial. In addition, they must either have had a hysterectomy or tubal ligation at least 6 months before signing informed consent, be post-menopausal for 1 year, or practicing an acceptable method of birth control. An acceptable method of birth control may be oral, injectable or implantable hormonal contraceptives, intrauterine device, diaphragm plus spermicide, or female condom plus spermicide. Abstinence, partner's use of condoms, and partner's vasectomy are NOT acceptable methods of contraception
  • BMI 25 - 45 kg/M sq, inclusive

You may not qualify if:

  • Subjects are excluded from participation in the study if any of the following criteria apply:
  • Type 1 diabetes mellitus or history of diabetic ketoacidosis
  • Treatment with lipid or blood pressure lowering therapy that has not been stable for three months before randomization
  • Treatment with WelChol, cholestyramine or colestipol for hyperlipidemia within the last 3 months
  • Treatment with thiazolidinediones
  • History of dysphagia, swallowing disorders, or intestinal motility disorder
  • Serum triglyceride \>500 mg/dL at Visit 1
  • Serum LDL-C \<60 mg/dL at Visit 1
  • Any condition or therapy which, in the opinion of the investigator, poses a risk to the subject or makes participation not in the subject's best interest
  • Use of any investigational drug within 30 days before randomization
  • Chronic treatment with oral corticosteroids
  • History of hyperthyroidism and/or treatment with thyroid hormone/ levothyroxine
