Study information

Scientific 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 (ProCAID)



Study hypothesis

Docetaxel and prednisolone chemotherapy (DP) is the only treatment proven to extend survival as first line chemotherapy in metastatic castration resistant prostate cancer (mCRPC). Clinical benefit from DP is modest however and DP resistance is a common problem raising a pressing clinical need to build on the benefits of DP.
One approach to this is to develop a rational combination of docetaxel with a drug with likely clinical synergy and complimentary toxicity profile that might circumvent DP resistance. AKT (Protein Kinase B) activation is common in prostate cancer reaching up to 100% in metastatic disease. This contributes to disease progression and DP resistance. AZD5363 is an orally available potent AKT inhibitor. The ProCAID trial will test the hypothesis that AZD5363 prolongs progression free survival when combined with DP for mCRPC.

Participant inclusion criteria

1.Histologically or cytologically proven mCRPC with documented metastases (measurable or evaluable disease is acceptable) now eligible for treatment with docetaxel chemotherapy
2.Disease progression since the last change in therapy defined by one or more of the following according to the Prostate Cancer Working Group (PCWG2) criteria (J Clin Oncol 2008¿26:11481159):
2.1. PSA progression as defined by the prostate cancer working group (2) (PCWG2) criteria (Scher et al. 2008 J Clin Oncol. 26¿ 1148). This must be based on a series of at least 3 readings at least 7 days apart. The 3rd reading must be >= 2ng/ml. In the event where an intermediate reading is lower than a previous reading, then the patient will still be eligible (ie. the 3 readings do not need to be consecutive). The first of the three readings must have been obtained after commencing the previous systemic therapy, or, in the case of androgen receptor antagonists, after discontinuing.
2.2. Radiographic progression of nodal or visceral metastases as defined by RECIST version 1.1 (Eur J Cancer 2009¿45:228). See Appendix 5
2.3. The appearance of two or more new bony metastases
3.Serum testosterone <1.7 nmol/L (ongoing LHRH analogue or antagonist therapy is permitted to maintain a castrate state)
4.Discontinuation of prior therapies for prostate cancer ≥ 4 weeks prior to commencing study treatment (with the exception of an LHRH agonist or antagonist where required for ongoing testosterone suppression)
5.No antiandrogen withdrawal response. Withdrawal responses typically occur following combined androgen blockade (LHRH analogue/antagonist or orchidectomy combined with an antiandrogen)
as initial therapy for a prolonged period, or in patients who respond to an antiandrogen as secondline therapy. Consistent with PCWG2
guidelines, investigators should evaluate such patients for withdrawal response for 6 weeks and then confirm disease progression. Investigators need not wait to assess withdrawal response in patients who did not respond, or who showed a PSA decline for ≤ 3 months, after an antiandrogen was administered as a secondline or later intervention
6.ECOG performance status 0 or 1
7.Hb ≥ 9g/dL¿ platelets ≥ 100 x 109/L¿ neutrophils ≥ 1.5 x109/L
8.Bilirubin ≤ ULN ¿ ALT and AST ≤ 1.5 x ULN.
9.Sodium and potassium within the normal range for the site
10.Able to swallow study drugs (without crushing/opening in the case of AZD5363)
11.Life expectancy > 3 months
12.Aged 18 years or over
13.Provision of written informed consent

Target number of participants

Planned Sample Size: 150; UK Sample Size: 150; Description: England: Phase 1 – up to 12, Phase II - 105N. Ireland: Phase II - 9Scotland: Phase 1 – up to 6, Phase II - 9Wales: Phase II - 9

Participant exclusion criteria

1.Previous treatment with cytotoxic chemotherapy (patients may have received previous or ongoing bisphosphonates or denosumab). There are no restrictions on prior use of second generation hormonal therapies e.g. abiraterone, enzalutamide
2.Prior malignancy with an estimated ≥ 30% chance of relapse within 2 years following curative treatment
3.Previously identified brain metastases, or spinal cord compression unless treated with full functional recovery
4.Prior radiotherapy to > 30% of bone marrow

6.Type I or II diabetes mellitus requiring either insulin or oral hypoglycaemics for routine management. Patients with type II diabetes mellitus that is well controlled by dietary measures alone are eligible to participate. Patients found to have a fasting glucose ≥7 mmol/L (≥126 mg/dL) or glycosylated haemoglobin >8% (64 mmol/mol) at screening should be assessed for appropriate management according to local policy.
