Muvalaplin, an Oral Small Molecule Inhibitor of Lipoprotein(a) Formation: A Randomized Clinical Trial
Authors' conclusion
Muvalaplin, a selective small molecule inhibitor of Lp(a) formation, was not associated with tolerability concerns and lowered Lp(a) levels up to 65% following daily administration for 14 days.
Study context

Primary result
As reported in the abstract
Lp(a) lowering (multiple ascending dose) · 14 days
Maximum placebo-adjusted Lp(a) reduction
63% to 65%
Participants reaching Lp(a) <50 mg/dL
93%
Further findings
Pharmacokinetics (30 mg to 800 mg daily for 14 days)
- Increasing plasma concentrations; half-life
- 70 to 414 hours
Safety
Tolerability, adverse effects and plasminogen
- No tolerability concerns or clinically significant adverse effects
- No clinically significant changes in plasminogen levels or activity
