ANRS 132 : Study Design and Objectives Randomized, partly blinded, open-label, non-inferiority study Primary objective: demonstrate non-inferiority of Polyacrylamide gel vs. Polylactic acid injections in patient satisfaction at week 48 as assessed by a visual analogue scale score (VAS). Primary analysis Week 48 End of study W 96 Injections Week 0 4 8 12 16 20 24 148 patients randomized Polylactic Acid (N=73) • ARV-experienced pts, 18 yrs • ART-induced lipoatrophy • No previous facial injection • CD4 cell count >100 c/mm3 • No d4T • Normal coagulation tests Polyacrylamide Gel (N=75) Patients stratified by severity of lipoatrophy* *as assessed by the baseline satisfaction visual analogue scale score

ANRS 132 : Safety Summary *assessed by a visual analogue scale
ANRS 132 : Conclusions • Polyacrylamide hydrogel is non-inferior to polylactic acid for the treatment of facial lipoatrophy • Both treatments were associated with high patients satisfaction scores. • Polyacrylamide hydrogel is associated with more pain during injections. • Long-term inflammatory reactions at the injection site are a concern with polyacrylamide gel • Long-term follow-up is in progress
