YONDELIS® (trabectedin) Efficacy

YONDELIS® (trabectedin) EFFICACY

YONDELIS® significantly improved progression-free survival (PFS)1

YONDELIS® is the first FDA-approved treatment for liposarcoma and leiomyosarcoma studied against an active comparator in a phase 3 trial.1

VIEW THE STUDY DESIGN

YONDELIS® improved median PFS* vs dacarbazine:

(HR=0.55; 95% CI: 0.44, 0.70; P<0.001)1

*

An exploratory analysis of independent radiology committee-determined PFS,§ in a subgroup consisting of approximately 60% of the total population, provided similar results to the investigator-determined PFS.

Hazard ratio (HR) is estimated using Cox proportional hazards model with treatment group as the only covariate.

P value is based on unstratified log-rank test.

§

The time from randomization to the occurrence of disease progression or death, whichever occurred first.2

CI=confidence interval; FDA=US Food and Drug Administration; HR=hazard ratio.

In a subgroup analysis of PFS, YONDELIS® demonstrated activity in both leiomyosarcoma and liposarcoma3

Overall survival=the time between randomization and death from any cause.2

Objective response rate=percentage of patients achieving complete response or partial response.2

Duration of response=duration of response for patients with complete response or partial response.2

CR=complete response; NE=not estimable; PR=partial response.

HR is estimated using Cox proportional hazards model with treatment group as the only covariate.1

P value is based on unstratified log-rank test.1

YONDELIS® (trabectedin) study design1

YONDELIS® was studied in a phase 3 randomized, open-label, active-controlled, multicenter trial of patients (N=518) with unresectable, locally advanced or metastatic leiomyosarcomas (73%) or liposarcomas (27%).
