Part A, Regimen 2
Arm Description
AT13387 given as a 1-hr IV infusion at a starting dose of 220 mg/m2 once weekly for 3 weeks in a 4-week cycle, in combination with abiraterone acetate 1000 mg by mouth (PO) daily (QD) and prednisone or prednisolone 5 mg PO twice daily.
At13387 administered as a 1-hr IV infusion at a starting dose of 120 mg/m2 on Day 1 and Day 2 weekly for 3 weeks in a 4-week cycle, in combination with abiraterone acetate 1000 mg by mouth (PO) daily (QD) and prednisone or prednisolone 5 mg PO twice daily.
Outcomes
Primary Outcome Measures
Part A: Safety and tolerability of the combination of AT13387 and abiraterone and to select the most promising treatment regimen in CRPC patients who are no longer responding to treatment with abiraterone alone.
Number of patients with adverse events
Change in prostate specific antigen measurement and circulating tumor cell count every 4 weeks
Change in tumor measurements by RECIST 1.1 every 12 weeks
Part B: Compare the antitumor activity (response rate per the Prostate Cancer Working Group 2 [PCWG2]) between single-agent AT13387 and combination of AT13387 plus abiraterone in patients who are no longer responding to treatment with abiraterone alone.
Change in prostate specific antigen measurement and circulating tumor cell count every 4 weeks
Change in tumor measurements by RECIST 1.1 every 12 weeks
Secondary Outcome Measures
Pharmacokinetics of combination treatment of AT13387 and abiraterone.
Area under the plasma concentration versus time curve (AUC) of AT13387 and abiraterone alone and in combination by Week 4
Maximum concentration (Cmax) of AT13387 and abiraterone alone and in combination by Week 4
Pharmacodynamics of combination treatment of AT13387 and abiraterone.
CTC enumeration and characterization every 4 weeks.

5. Study Description
Brief Summary
A 2-part, Phase 1-2, open-label, parallel group, randomized study in patients with Castration-Resistant Prostate Cancer (CRPC) who are no longer responding to treatment with abiraterone and steroids. In Part A (Phase 1), patients will continue to receive the same doses of abiraterone and steroids they were receiving prior to study entry and will be randomized to receive 1 of 2 different treatment regimens of AT13387 in combination with abiraterone. Once the best regimen is established in Part A, based on safety and antitumor activity, patients will be randomized to the selected treatment regimen and dose of AT13387 in combination with abiraterone or AT13387 alone in Part B (Phase 2).
