The safety of VANTAS was evaluated in 171 patients with prostate cancer treated for up to 36 months in 2 clinical trials. The pivotal study (study 301) consisted of 138 patients, while a separate supportive study (study 302) consisted of 33 patients.

In a multi-year clinical study, 94% of patients (n=113) elected to receive a second implant following their first year of treatment.5*

VANTAS, like other GnRH agonists, causes a transient increase in serum concentrations of testosterone during the first week of treatment.

*Open-label multicenter phase 3 study in 138 patients with prostate cancer treated with a single VANTAS implant and evaluated for at least 60 weeks. At week 52, the study included the option for removal and insertion of a new implant, with evaluation for an additional 52 weeks. A total of 120 patients completed the initial 52-week treatment period. 113 patients underwent removal of the first implant and insertion of a second implant for another year of therapy.3,5
