load (<50 copies/mL) vs. 75 percent of patients in the lopinavir/r
arm, (p=not significant).
-- Of patients with baseline CD4+ cell count less than 200 cells per cubic
millimeter, 79 percent of patients in the PREZISTA/r arm reached an
undetectable viral load (<50 copies/mL) vs. 65 percent of patients in
the lopinavir/r arm, (p=0.009).
-- Of patients with baseline CD4+ cell count greater than 200 cells per
cubic millimeter, 79 percent of patients in the PREZISTA/r arm reached
an undetectable viral load (<50 copies/mL) vs. 75 percent of patients
in the lopinavir/r arm, (p=not significant).
ARTEMIS Safety Findings
-- Incidence of grade 2-4 treatment-related diarrhea reported in the
PREZISTA/r arm was four percent vs. 11 percent in the lopinavir/r arm.
Nausea was reported in two percent vs. three percent, respectively.
-- In both treatment arms, grade 2-4 treatment-related rash occurred
infrequently; three percent in the PREZISTA/r arm vs. one percent in the
lopinavir/r arm.
-- Discontinuations due to adverse events were four percent in the
PREZISTA/r arm vs. nine percent in the lopinavir/r arm.
Dosing
Recommended dosing for treatment-naive adult patients is 800 mg (two 400 mg tablets) taken with 100 mg ritonavir once daily with food. The new 400 mg tablet will be available by November 1. For treatment-experienced adult patients, the dosing for PREZISTA remains 600 mg taken with 100 mg ritonavir twice daily with food. PREZISTA must be taken in combination with other ARVs. PREZISTA/r is not recommended for use in patients with severe hepatic impairment.
