Study of MB07811 in Subjects With Hypercholesterolemia

Phase 2, Randomized, Double-Blind, Placebo-Controlled, Multicenter Study to Assess the Efficacy, Safety, and Tolerability of MB07811 for 12 Weeks Followed by a 6-Week Off Drug Phase in Subjects With Primary Hypercholesterolemia

A Phase 2 randomized, placebo controlled study assessing the efficacy, safety, and tolerability of MB07811 given orally to subjects with primary hypercholesterolemia for 12 weeks followed by a 6-week off drug phase.

This is an outpatient, Phase 2, multicenter, double-blind, placebo-controlled, randomized, parallel-group study assessing the efficacy, safety, and tolerability of MB07811 given orally to subjects with primary hypercholesterolemia for 12 weeks. There will be a 3- to 6-week screening/run-in period, including washout of any lipid-modifying therapies (as needed) prior to randomization. Eligible subjects will be randomized (1:1:1:1) to placebo, or 3 different doses of MB07811 for 12 weeks. After the double-blind treatment phase, all randomized subjects will proceed into a 6-week off-drug phase. Assessments include: laboratory tests, adverse events (AEs), electrocardiograms (ECGs), vitals, and PK samples.
