Details and patient eligibility

About

This is a multi-center, double blind, prospective, longitudinal, randomized, 12-week study with a 52-week open-label follow-up to evaluate the safety and efficacy of daily administration of Pravastatin 40 mg or Fenofibrate 160 mg or Pravafen (the combination of both Pravastatin and Fenofibrate 40/160 mg) in the treatment of combined hyperlipidemia. There will be an open-label, 8-week, Selection Phase prior to randomization in which all patients will be stabilized on Pravastatin 40 mg/day. Following the Selection Phase, and if the patients meet all inclusion/exclusion criteria, they will be randomized to a three arm, double blind, 12-week Efficacy Phase during which they would receive either Pravastatin 40 mg or Fenofibrate 160 mg or Pravafen (the combination of Pravastatin and Fenofibrate 40/160 mg). The 12-week Efficacy Phase will be followed by an open-label, 52-week, Safety Phase in which all patients will receive Pravafen.

After the 8-week Selection Phase, patients that still meet the inclusion/exclusion criteria will be randomized on a 1:1:2 ratio to Pravastatin 40 mg or Fenofibrate 160 mg or Pravafen (the combination of both Pravastatin and Fenofibrate 40/160 mg) for 12 weeks. After the completion of the 12-week double-blind phase of the study, all patients that haven't had changes in their well being, will be allowed to roll-over into the 52-week, open-label, follow-up portion of the study. During the 52 week, open label, Safety Phase of the study, all patients will receive Pravafen (the combination of Pravastatin and Fenofibrate 40/160 mg).

Patients will be evaluated at baseline and every three weeks thereafter throughout the initial 12-week Efficacy Phase of the study. Patients that roll-over into the 52-week, open-label, follow-up Safety Phase will be evaluated at 12, 24, 36 and 52 weeks.

Participation in the study can be up to 72 weeks.

Enrollment: 481 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Patients meeting all the criteria listed below may be selected to enroll into the Selection Phase of the study:

   * A patient that has received NO lipid lowering therapy within 6 weeks prior to the Selection Visit, will be considered Naïve to treatment.

3.

4. Able to comply with all study procedures.

5. Patients that provide a written informed consent to participate in the study indicated by a personal signature and date on the patient consent form.

At the end of the Selection Phase, patients meeting all of the criteria listed below may be selected and randomized into the Efficacy Phase of the study:

1. Selected patients with LDL Cholesterol ≥ 100 mg/dl and/or TG ≥ 150 mg/dl and ≤ 400 mg/dl at Week-1 / Visit 2 after taking Pravastatin 40 mg/day from Visit 1.
2. Patients still meeting the selection criteria a, c, d and e as listed under section 4.1.
3. Patients with a compliance ≥ 80% during the 8-week Pravastatin phase of the study.
