In (1), they studied the effect of niacin and neomycin combined, but niacin
alone works too (2).

From (1):

"Neomycin (2g/day) reduced low density lipoprotein cholesterol and lipoprotein
Lp(a) concentrations by 23% and 24%, respectively. Combination
therapy with neomycin (2 g/day) and niacin (3 g/day) induced a 48%
decline in low density lipoprotein cholesterol levels and a 45% reduction
in the concentration of lipoprotein Lp(a)"

From (2):

"This study examines the effect of nicotinic acid (1 g t.d.s.) on serum
Lp(a) concentration in a group of patients with type II hyperlipidaemia
selected on the basis of a plasma Lp(a) concentration greater than 30
mg/dl. Reductions in total cholesterol, triglyceride, LDL-cholesterol
and Lp(a) were 16.3%, 25.5%, 23.7% and 36.4%, respectively, with an
increase in HDL cholesterol of 37.3%."
