E.2.1 | Main objective of the trial |
Part A. Safety run-in: To assess the safety and tolerability of two intermittent dosing schedules of AZD5363 when combined with weekly paclitaxel in patients with advanced or metastatic breast cancer; and to recommend, by assessment of dose limiting toxicities and other safety, tolerability, pharmacokinetic and pharmacodynamic data, a dose and schedule of AZD5363 for further study when combined with weekly paclitaxel.
Part B. Randomised expansion: To assess the relative efficacy of AZD5363 when combined with weekly paclitaxel compared with weekly paclitaxel plus placebo by assessment of progression-free survival in the overall advanced or metastatic Estrogen Receptor positive breast cancer population and in a Phosphoinositide 3-kinase (PIK3CA) mutation-positive sub-population. |
|
E.2.2 | Secondary objectives of the trial |
Part A:To assess anti-tumour activity of AZD5363+paclitaxel by objective response rate and % of patients without progressive disease at 12 w.
Part B:To assess relative efficacy of AZD5363+paclitaxel vs.paclitaxel+placebo by objective response rate at 12 w., best objective response, durable response rate and duration of response.To assess relative antitumour activity of AZD5363+paclitaxel vs.paclitaxel+placebo by change in tumour size at 12 w.To compare overall survival in patients treated with AZD5363+paclitaxel vs. paclitaxel+placebo by time to death.To further assess safety and tolerability of AZD5363+paclitaxel vs.paclitaxel+placebo.To investigate effects on patients' quality of life of AZD5363+paclitaxel vs.paclitaxel+placebo by changes from baseline, using a patient questionnaire.
PartsA and B:To assess PK ofAZD5363 and paclitaxel alone and in combination.To assess relationship between plasma AZD5363 exposure and concentrations of plasma biomarkers; toxicity burden of diarrhoea. |

E.5 End points |
E.5.1 | Primary end point(s) |
Part A: Safety and tolerability of AZD5363 when combined with paclitaxel, in terms of numbers of patients with adverse events and serious adverse events.
Part B: Relative efficacy of AZD5363, compared to placebo, when combined with paclitaxel, by assessment of progression-free survival. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Regular assessments, to include vital signs, clinical chemistry, haematology and ECGs, will be conducted from screening, throughout the period that patients receive AZD5363/placebo and paclitaxel, up to 28-days following discontinuation of study treatments. Tumour assessments by RECIST 1.1 will be conducted at baseline and every 12 weeks up to disease progression or withdrawal of consent. Recording of adverse events will be conducted from screening, throughout the period that patients receive AZD5363/placebo and paclitaxel, up to 28-days following discontinuation of study treatments. In Part B, serious adverse events that are considered related to study procedures will be recorded up to disease progression. |
|
E.5.2 | Secondary end point(s) |
Part A: Preliminary anti-tumour activity of AZD5363 when combined with paclitaxel, by assessment of overall response rate (ORR) and percentage of patients without progressive disease at 12 weeks.
Part B: Relative efficacy of AZD5363, compared to placebo, when combined with paclitaxel, by assessment of ORR at 12 weeks, best objective response (BOR), duration of response (DoR) and durable response rate (DRR).
Part B: Relative anti-tumour activity of AZD5363, compared to placebo, when combined with paclitaxel, by comparison of change in tumour size at 12 weeks.
Part B: Safety and tolerability of AZD5363 when combined with paclitaxel,in terms of numbers of patients with adverse events and serious adverse events.
Part B: Effect on patient's quality of life (QoL) due to receipt of AZD5363 when combined with paclitaxel, by assessing changes from baseline score in a patient-completed QoL questionnaire (EORTC QLQ-30 / BR-23).
Parts A and B: Assessment of the plasma concentration profile of AZD5363 when combined with paclitaxel.
Parts A and B: Assessment of the plasma concentration (PK) profile of paclitaxel alone and when combined with AZD5363
Parts A and B: Assessment of the pharmacokinetic/pharmacodynamic relationship between plasma concentration of AZD5363 and plasma concentrations of pharmacodynamic biomarkers and correlation with anti-tumour activity.
Parts A and B: To assess the toxicity burden associated with diarrhoea in relation to the number of episodes, duration of episodes and variations in intensity within episodes of the event's occurrence.
Part B: Overall survival of patients treated with AZD5363, compared to
placebo, when in combination with paclitaxel by assessment of time to
death. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Regular assessments, including vital signs, clinical chemistry, haematology and ECGs, will be conducted from screening to 28-days after discontinuation of study treatments. Multiple blood samples for PK/PD assessments will be taken during the first 28-day cycle. Blood sampling for: glycosylated haemoglobin, lipids, circulating tumour cells, and assessment of: MUGA/Echo, QoL and RECIST 1.1, will be conducted every 12 weeks from baseline to disease progression or withdrawal of consent. Adverse events will be recorded from screening to 28-days after discontinuation of study treatments. Part B: serious adverse events that are considered related to study procedures will be recorded up to disease progression; patients will be followed for survival status to death or withdrawal of consent. |
