| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
• Determine whether dual inhibition of mTORC 1 and mTORC2 with AZD2014 will increase the anti-tumour activity of endocrine treatment with fulvestrant in ER-positive advanced or metastatic breast cancer.
• Determine whether inhibition of both mTORC 1 and mTORC2 using AZD2014 will have superior anti-tumour activity compared to inhibition of mTORC1 alone with everolimus, when combined with fulvestrant
• Evaluate the efficacy and safety of an intermittent schedule of AZD2014 relative to continuous daily dosing of AZD2014
• Explore whether additional efficacy is likely to be present in a subgroup with PI3K-pathway activation for whom it is hypothesised that there will be greater sensitivity to mTOR inhibitors
• Characterize the patient population who might benefit from fulvestrant plus AZD2014 to identify potential predictors of sensitivity |
|
| E.2.2 | Secondary objectives of the trial |
- Estimate the clinical benefit, assess the clinical activity (measured by repsonse rate per RECIST 1.1), clinical benefit rate, duration of clinical benefit and duration of response and establish the safety and tolerability and overall survival benefit of the Fulvestrant + AZD2014 continuous and intermittent schedule relative to each other and Fulvestrant + Everolimus and Fulvestrant alone.
- Investigate the effects of fulvestrant +/- AZD2014 or everolimus on bone-turnover biomarkers
- Compare the differences in patient reported outcomes as measured by the Functional Assessment of Cancer Therapy-General (FACT-G) scale together with the Breast-Anti-A and Endocrine Symptom (FACTAnti-A-ES) subscales
- Investigate the pharmacokinetics of AZD2014 in breast cancer patients co-administered with fulvestrant
- Determine the minimum plasma concentration at steady state in breast cancer patients of fulvestrant alone and when administered in combination with AZD2014 or everolimus |
