Details and patient eligibility

About

This is a single center, open label, randomized, parallel design, single and multiple dose trial to evaluate the pharmacokinetics(PK), safety and tolerability of obeticholic acid (OCA).

Full description

Twenty-four eligible subjects will be enrolled and randomized to 1 of 3 treatment groups (5 mg, 10 mg, or 25 mg) in a treatment ratio of 1:1:1 and no less than a ratio of 1:1 for female: male subjects. The study comprises single dose and multiple dose phases. The randomized dose administered in the single dose phase will be the subject's dose level for the multiple dose phase. A single dose of OCA (5 mg, 10 mg, or 25 mg) will be administered on Day 1. PK, safety, and tolerability will then be assessed for 3 days. On Day 4, the multiple dose phase will begin at the same dose level (5 mg, 10 mg, or 25 mg), with subjects receiving OCA once daily for 14 days. PK, safety, and tolerability will be assessed for 2 weeks at the clinical site following the last investigational product (IP) dose on Day 17. Subjects will be confined at the inpatient trial site from Day 0 until the morning of Day 30. They will return to the study site on Day 37 for follow up.

Inclusion and exclusion criteria

Subjects are required to meet the following criteria in order to be included in the trial.

Males or females age 18 to 55 years

Contraception: Oral contraceptives are not allowed to be used for 2 weeks prior to trial start, during the trial, and for 30 days after the last dose of OCA. Therefore, female subjects must be postmenopausal, surgically sterile, or if premenopausal, be prepared to use more than 1 effective (≤ 1% failure rate) method of contraception during the trial and until at least 30 days after the last dose of OCA. Effective methods of contraception for males and females are considered to be the following:

  • Double barrier method, ie, (i) condom, with spermicide (male or female) or (ii) diaphragm with spermicide
  • Intrauterine device (IUD)
  • Vasectomy (partner)
  • Good general health as determined by medical history and by results of physical exam, vital signs, ECG, and clinical laboratory tests obtained within 14 days prior to IP administration
  • Body mass index (BMI) between 18 and 30 kg/m2; BMI is determined by the following equation: BMI = weight/height2 (kg/m2).
  • Willing to abstain from alcohol, caffeine, and xanthine containing food and beverages for 72 hours prior check in and during participation of the inpatient period of the trial
  • Willing and able to give written informed consent

Exclusion Criteria:

Subjects meeting any of the following criteria will be excluded from the trial:

  • Prior exposure to OCA (INT-747; 6-ECDCA)
  • History of known or suspected clinically significant hypersensitivity to OCA or any of its components
  • History or presence of any disease or condition known to interfere with the absorption, distribution, metabolism, or excretion of drugs including bile salt metabolism in the large intestine, eg, inflammatory bowel disease (IBD)
  • History of gastrointestinal surgeries or gall bladder removal (cholecystectomy)
  • History or presence of a clinically significant cardiovascular, hepatic, diabetic, gastrointestinal, metabolic, neurologic, pulmonary, endocrine, psychiatric, or neoplastic disorder(s)
  • History of known or suspected clinically significant hypersensitivity to any drug, aside from penicillin
  • Ingestion of a prescription medication, including oral contraceptives and bile acid sequestrants, within 14 days prior to IP dosing or ingestion of an over the counter medication within 7 days prior to IP dosing
  • Participation in radiologic examinations involving parenteral administration of iodinated contrast materials within 2 weeks prior to screening, or subsequently through the end of trial participation
  • History or presence of alcohol abuse (defined as consumption of more than 210 mL of alcohol per week, or the equivalent of fourteen 4 ounces [oz] glasses of wine or fourteen 12 oz. cans/bottles of beer or wine coolers per week) or positive alcohol tests
  • History or presence of substance abuse within the past 2 years or positive drug screen tests
  • Smoker or use of any tobacco or nicotine containing products
  • Any screening laboratory test for which the results are not within the normal reference range and considered clinically significant
  • Participation in another investigational drug trial within 30 days prior to Day 0
  • History of noncompliance to medical regimens, or subjects who are considered to be potentially unreliable
  • Blood or plasma donation within 30 days prior to Day 0
  • Mental instability or incompetence
  • Presence of human immunodeficiency virus (HIV), hepatitis C virus (HCV), or hepatitis B virus (HBV) at screening
  • Known or suspected Pregnancy
