On April 24, 2013, FDA approved revisions to the Prezista (darunavir) tablet and oral suspension label to update labeling with 48 week data from study TMC114-C228 for HIV-1 treatment experienced pediatric patients three to less than 6 years of age. The 48 week data is reflected in the Indications and Usage section and the following sections.

Section 6 Adverse Reactions
Study TMC114-C228
Clinical ADRs to PREZISTA/ritonavir (all grades, greater than or equal to 5%), were diarrhea (24%), vomiting (19%), rash (19%), abdominal pain (5%) and anorexia (5%).

Section 12 Clinical Pharmacology
Table 13 was updated to include the pharmacokinetic results from Study TMC114-C228

Section 14 Clinical Trials
Twenty subjects (95%) completed the 48 week period. One subject prematurely discontinued treatment due to vomiting assessed as related to ritonavir.

The proportion of subjects with HIV-1 RNA less than 50 copies/mL at Week 48 was 71%. The mean change in CD4+ percentage from baseline was 4%. The mean increase in CD4+ cell count from baseline was 187 x 106 cells/L.

The revised label will be made available at Drugs@FDA.
