Title

An open label phase I/randomised, double blind phase II study in metastatic castration resistant Prostate Cancer of AZD5363 In combination with Docetaxel and prednisolone chemotherapy

Description

A phase I/II trial to determine if the addition of the AKT inhibitor AZD5363 to docetaxel and prednisolone (DP) prolongs progression free survival (PFS) in metastatic castration resistant prostate cancer (mCRPC) to a degree worthy of further investigation.

Objectives

Primary Endpoints:

Phase I:

• Determination of a suitable dose of AZD5363 using a 4 days on/3 days off continuous schedule, in combination with DP

Phase II:

• Progression free survival (PFS) in patients receiving AZD5363 versus placebo when combined with DP in mCRPC

Secondary Endpoints:

Phase I:

• Safety and tolerability profiles using CTCAE version 4.03
• AZD5363 pharmacokinetics in combination with DP

Phase II:

• Overall survival
• Bone pain changes using the brief pain inventory
• PFS excluding biochemical (PSA) alone progression
• Biochemical (PSA) response rates according to PCWG2 criteria
• Safety and tolerability profiles using CTCAE version 4.03
  
  

Trial Design

ProCAID will first comprise a dose-finding, single arm, open label phase I study exploring the combination of AZD5363 and Docetaxel and prednisolone chemotherapy (DP). This will be followed by a double-blind, randomised phase II study comparing DP + AZD5363 with DP + placebo. All patients will have chemotherapy naive mCRPC and will be suitable for treatment with palliative docetaxel. Patients may, but are not required to, have had prior second generation anti-hormonal therapies (e.g., abiraterone, enzalutamide).

Phase I:

• AZD5363 at dose levels between 320 mg bd and 480 mg bd, taken 4 days on/3 days off, continuously starting from day 2 of cycle 1 of DP onwards.

Phase II:

• AZD5363 twice daily at a dose level ?defined in phase I (experimental arm) or matching placebo (control arm), taken 4 days on/3 days off, continuously from day 2 of cycle 1 of DP onwards.
