A Randomized, Double-Blind, Placebo-Controlled, Phase III Study of the Matrix Metalloprotease Inhibitor AG3340 in Combination With Mitoxantrone and Prednisone With Provision for Subsequent Change in Therapy in Patients Having Hormone-Refractory Prostate Cancer


OBJECTIVES: I. Compare symptomatic progression free survival among patients having
metastatic, hormone refractory prostate cancer receiving one of two doses of matrix
metalloprotease inhibitor AG3340 or placebo initially in combination with mitoxantrone and
prednisone with provision for subsequent change in therapy. II. Compare the symptomatic
response, quality of life, serologic (PSA) response, PSA progression free survival,
radiographic response, radiographic progression free survival, one year survival, and
overall survival of these patients. III. Evaluate the safety of AG3340 in regimen
combination and in combination with therapies administered subsequent to first line in this
patient population. IV. Evaluate the population pharmacokinetics of AG3340 when given in
this treatment regimen.

OUTLINE: This is a randomized, double blind, placebo controlled, multicenter study. Patients
receive the matrix metalloprotease inhibitor AG3340 (at one of two dosages) or placebo,
orally twice a day, beginning on day 1. Patients receive mitoxantrone by intravenous
infusion on day 1 and prednisone orally twice daily beginning on day 1. Treatment course is
repeated every 3 weeks in the absence of unacceptable toxicity. Mitoxantrone and/or
prednisone may be discontinued or switched at the investigator's discretion.

PROJECTED ACCRUAL: There will be 525 patients accrued into this study from approximately 50
centers.
