PALETTE was a randomized phase 3 trial (NCT00753688) that demonstrated single-agent activity of PAZ in advanced STS (aSTS). We evaluated the relationship between age, prior lines of therapy, and dose modifications on the safety and efficacy of PAZ in aSTS.


Median progression-free survival (mPFS) was evaluated in subgroups of prior lines of therapy (1 prior line; 2+ prior lines), age (


A total of 246 patients received pazopanib in the PALETTE study. Median PFS and median overall survival (OS) were longer in patients receiving PAZ who had only 1 prior line of therapy vs 2+ prior lines of therapy (mPFS, 24.7 vs 18.9 weeks [Table]; OS, 13.7 vs 11.3 months). In patients receiving PAZ, mPFS was similar in ages


Longer mPFS was observed in patients receiving PAZ following only 1 line of therapy. Additionally, mPFS with PAZ was maintained regardless of patient age or if dose modification was required to manage toxicity.
