In a major head-to-head study comparing the efficacy of statin
medications among people living with HIV, Livalo (pitavastatin) proved
superior to Pravachol (pravastatin) on numerous measures, MedPage Today
reports.
Publishing their findings in The Lancet HIV,
researchers from the randomized, double-blind, active-controlled, Phase
IV INTREPID study recruited people with well-treated HIV between the
ages of 18 and 70 who had been taking antiretroviral (ARV) treatment for
at least six months and had dyslipidemia (abnormally elevated
cholesterol or fats in the blood—a condition, researchers said, that may
occur in up to 80 percent of people living with HIV).
Between
February 2011 and March 2013, the researchers randomized the
participants to receive 4 milligrams of Livalo or 40 mg of Pravachol
with matching placebo tablets once daily for 12 weeks. Participants
could also participate in an additional 40 weeks of the study, intended
for an analysis of drug safety (unlike many other statins, Livalo and
Pravachol are not restricted in their use with protease inhibitors).
The
average age of the participants was 50; 86 percent of them were men.
Ten percent also had hepatitis B or C virus (HBV/HCV).
A
total of 224 individuals participated in the initial 12 weeks of the
study, with 190 of them completing all 52 weeks of follow-up. A total of
27 of those receiving Livalo and 35 of those who received Pravachol
dropped out of the study because of adverse health events.
After
12 weeks of treatment, those receiving Livalo experienced an average 31
percent reduction in LDL cholesterol, compared with 21 percent among
those receiving Pravachol. The superior performance of Livalo persisted
through the 52-week mark as well as after the researchers controlled the
data for hep B and C status and certain types of ARVs, including
Sustiva (efavirenz) and Norvir (ritonavir).
In
addition, those who took Livalo, compared with those receiving
Pravachol, saw greater reductions in variables that contribute to fatty
plaques in arteries, including non-HDL cholesterol and apolipoprotein B.
Eighty-five
of 126 people who received Livalo and 88 of 126 people who received
Pravachol experienced adverse health events. Sixty percent of these
health events were mild, and 29 percent were moderate. The most common
adverse health event among those on Livalo was diarrhea, while the most
common among those on Pravachol was upper respiratory tract infection.
