Summary
Brief summary
This is a randomized, double-blind, placebo-controlled, multicenter, multiple ascending dose
(MAD) study to evaluate the safety and tolerability, pharmacokinetic (PK), and
pharmacodynamic (PD) profiles of HTD1801 in overweight to obese adults with
hypercholesterolemia. There were 3 cohorts of dose levels as 500, 1000 and 2000 mg/day, with
16 subjects planned for each cohort randomized 3:1 to receive either HTD1801 or Placebo.
