STA-9090 in Castration-Resistant Prostate Cancer With Assessment of Androgen Receptor Pathway Signaling

Phase 2
Withdrawn
Conditions
Adenocarcinoma of the Prostate
Interventions
Registration Number
NCT01368003
Lead Sponsor
Toni Choueiri, MD
Brief Summary

In this research study, the investigators are looking to determine the safety and efficacy of an investigational drug, STA9090 alone and in combination with dutasteride for the treatment of castrate resistant prostate cancer. STA9090 may cause the growth of cancer to slow down or shrink by targeting proteins required for the cancer to grow. The investigators are also looking to determine whether the use of dutasteride to lower male hormone levels will enhance the effect of STA9090 in the treatment of castrate resistant prostate cancer.

Detailed Description

Subjects will have a tumor biopsy before treatment begins. Subjects who are randomized to Arm A will receive infusions of STA9090 on days 1, 8, and 15 of a 28 day cycle. Subjects randomized on Arm B will receive daily oral dutasteride for 2 weeks prior to beginning STA9090 treatment. They will continue to receive dutasteride while on study.

Primary Outcome Measures
NameTimeMethod
To assess AR transcriptional activity based on expression of a series of AR regulated genes, in baseline and on therapy tumor biopsies in CRPC patients treated with STA- 9090 +/-dutasteride.2 years

The primary objective is to determine whether STA-9090, or the combination with dutasteride further suppresses AR transcriptional activity. AR transcriptional activity will be assessed based on expression of a series of AR regulated genes, in baseline and on therapy tumor biopsies in CRPC patients treated with STA-9090 +/- dutasteride.

Secondary Outcome Measures
NameTimeMethod
To evaluate progression-free survival (PFS) of men with CRPC treated with STA9090 with or without dutasteride2 years

PFS will be summarized using K-M method.

To determine the response rate of measurable disease if present (RECIST)2 years

Patients with measurable disease will be evaluated for response using RECIST criteria and summarized descriptively.

To assess the safety and tolerability of STA9090 in men the CRPC2 years

Each type of toxicity rate (a proportion) will be analyzed and summarized descriptively.

To evaluate the overall survival of men with metastatic CRPC treated with STA9090 alone or in combination with dutasteride2 years

OS will be summarized using K-M method.
