Condition(s) targeted: Hypercholesterolemia; Hyperlipidemia

Intervention: Vytorin + Niaspan (Drug); Vytorin (Drug); Niaspan (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Merck Sharp & Dohme Corp.


This is a single-center, randomized, open-label, 3-period, 3-treatment multiple-dose crossover study designed to assess the interaction between VYTORIN« (Ezetimibe and Simvastatin) and NIASPAN« (Niacin Extended-Release Tablets) in healthy subjects. Treatment spans 7 days

Clinical Details

Official title: SCH 465981: Assessment of Bi-Directional Interaction Between Components of Vytorin« (Ezetimibe and Simvastatin) and Niaspan« (Niacin Extended-Release Tablets) in Healthy Subjects

Study design: Allocation: Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Evaluate the potential for a PK interaction between NIASPAN and components of VYTORIN, using Tmax, Cmax, and AUC.

Secondary outcome: Evaluate safety and tolerability: laboratory test results, ECGs, adverse events, vital signs.


Minimum age: 18 Years. Maximum age: 55 Years. Gender(s): Both.


Inclusion Criteria: The subject must meet ALL the criteria listed below for entry:

- Subjects must be willing to give written informed consent and able to adhere to dose

and visit schedules.

- Subjects of either sex and of any race between the ages of 18 and 55 years,

inclusive, having a Body Mass Index (BMI) between 19 to 32, inclusive. BMI = weight (kg)/height (m^2).

- Subjects' clinical laboratory tests (CBC, blood chemistry, and urinalysis) must be

within normal limits or clinically acceptable to the investigator/sponsor. Subject's liver function test results (AST, ALT, and GGT) must not be elevated above normal limits at Screening and on Day-1. Subjects' CPK test results must not be elevated

more than 1. 25 times the upper limit of normal, at Screening and on Day - 1.

- Subjects must be free of any clinically significant disease that would interfere with

the study evaluations.

- Screening ECG conduction intervals must be within gender specific normal range (QTc

males <=430 msec and females <=450 msec).

- Vital sign measurements (taken after ~3 minutes in a seated position) must be within

the following ranges:

- oral body temperature between 35. 0┬░C to 37. 5┬░C

- systolic blood pressure, 90 to 140 mm Hg

- diastolic blood pressure, 45 to 90 mm Hg

- pulse rate, 40 to 100 bpm

- Female subjects of childbearing potential must have a negative serum pregnancy test

(beta-hCG) at Screening and have a negative urine pregnancy test upon each admission to the study center.

- Women of child-bearing potential must agree to use medically accepted methods of

contraception prior to screening, while receiving protocol-specified medication, and for 30 days after stopping the medication. Acceptable methods of contraception include:

- Condoms (male or female) with spermicide,

- Diaphragm or cervical cap with spermicide

- Medically prescribed IUD with spermicide, and

- Surgical sterilization (eg. hysterectomy or tubal ligation). Vasectomy of the

partner should be considered a single barrier and one additional contraceptive methods listed above must be used. Females who are not currently sexually active must agree and consent to use one of the above-mentioned methods should they become sexually active while participating in the study.

- Female subjects must be surgically sterilized (eg, documented hysterectomy or tubal

ligation) or be postmenopausal. (Defined as 12 months with no menses and with an estradiol level of <30 pg/mL.)

- Men must agree to use a medically accepted method of contraception prior to

Screening, while receiving protocol-specified medication, and for 30 days after stopping the medication. Exclusion Criteria: The subject will be excluded from entry if ANY of the criteria listed below are met:

- Female subjects who are pregnant, intend to become pregnant (within 3 months of

ending the study), or are breastfeeding.

- Subjects who, in the opinion of the investigator, will not be able to participate

optimally in the study.

- Any surgical or medical condition which might significantly alter the absorption,

distribution, metabolism or excretion of any drug. The investigator should be guided by evidence of any of the following and be discussed with the sponsor prior to enrollment into the trial:

- history or presence of inflammatory bowel disease, ulcers, gastrointestinal or

rectal bleeding;

- history of major gastrointestinal tract surgery such as gastrectomy,

gastroenterostomy, or bowel resection;

- history of pancreatic injury or pancreatitis;

- history or presence of liver disease or liver injury;

- history or presence of impaired renal function as indicated by abnormal

creatinine, urinary albumin, BUN/urea or clinical significant urinary cellular constituents (eg, cast); or

- history of urinary obstruction or difficulty in voiding.

- Subject who has a history of any infectious disease within 4 weeks prior to drug


- Subjects who are positive for hepatitis B surface antigen, hepatitis C antibodies or


- Subjects who have a positive screen for drugs with a high potential for abuse.

- Subjects with a history of mental instability or who have been treated for mood


- Subjects with a history of alcohol or drug abuse in the past 2 years.

- Subjects who have donated blood in the past 60 days.

- Subjects who have previously received and demonstrated intolerance to NIASPAN®

(niacin extended-release tablets), VYTORIN® (ezetimibe/simvastatin), ZETIA® (ezetimibe), ZOCOR® (simvastatin) or products containing niacin/nicotinic acid.

- Subjects who are currently participating in another clinical study or have

participated in a clinical study within 30 days.

- Subjects who are part of the study staff personnel or family members of the study

staff personnel.

- Subjects who have demonstrated allergic reactions (eg, food, drug, atopic reactions

or asthmatic episodes).

- Subjects who smoke more than 10 cigarettes or equivalent tobacco use per day.
