A Phase II Study of AT-101 to Overcome Bcl-2--Mediated Resistance to Androgen Deprivation Therapy in Patients With Newly Diagnosed Castration-Sensitive Metastatic Prostate Cancer.

ABSTRACT:

Unlabelled

In a phase II multicenter study, men with castration sensitive metastatic prostate cancer were treated with AT-101, a small molecule Bcl-2 inhibitor, and androgen deprivation therapy. At the end of 7 cycles of therapy in 55 patients, an undetectable PSA was achieved in 31%. However, the combination did not meet the pre-specified level of activity for further development.

Background

We conducted a phase II study in men with castration-sensitive metastatic prostate cancer to test the hypothesis that AT-101, a small molecule Bcl-2 inhibitor, has clinical activity in patients initiating androgen deprivation therapy (ADT) for metastatic prostate cancer.

Materials and methods

Patients with metastatic prostate cancer scheduled to start, or who had recently (within
