E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Prospective validation of biomarkers indicating phosphoinositide-3-kinase pathway activation for breast cancer treatment. This substudy aims to improve “personalized” treatment options for patients with metastatic, estrogen receptor (ER)-positive breast cancer, the leading cause of breast cancer-related mor-tality in Germany. This shall be achieved by validating robust, highly sensitive and noninvasive technologies for detection of genomic biomarkers, by refinement of the diagnostic panel for prediction of response to pharmacologic inhibitors of the phosphoinositide-3-kinase (PI3K) pathway based on comprehensive genomic analyses, and prospectively by nominating novel therapeutic targets. Specific aims of the substudy are: -To validate noninvasive detection assays of genomic biomarkers associated with PI3K pathway activation for prediction and monitoring of response to pharmacologic PI3K pathway modulation in ER-positive metastatic breast cancer. -To develop and validate multiplexed, targeted biomarker profiling using next generation sequencing technology in diagnostic tumor samples from breast cancer patients pro-spectively enrolled in the screening and treatment phases of the PIKTAM study -To conduct comprehensive genome analyses in diagnostic tumor samples (i) to identify novel and more refined genomic signatures associated with clinical outcome in response to pharmacologic PI3K pathway modulation, and (ii) to prospectively nominate novel therapeutic targets for improvement of PI3K-directed therapies in ER-positive metastatic breast cancer. |

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
-Progression free survival (PFS)- rate in the subpopulations after 6 months of combination therapy -PFS in subpopulations and full population. PFS is defined as time from date of start of treatment to the date of the event, defined as the first documented disease progression or death due to any cause per local investigator assessment -OS in subpopulations and full population. OS is defined as time from date of start of treatment to the date of death from any cause. - ORR in subpopulations and full population. ORR is defined as the proportion of patients with best overall response of complete response (CR) or partial response (PR) - DCR in subpopulations and full population. DCR is defined as the proportion of patients with best overall response of complete response (CR) or partial response (PR) or stable disease (SD) lasting more than 12 weeks -Type, frequency and severity of adverse events per CTCAE v4.03 -Change in depressive episodes assessed by PHQ-9 questionnaire and GAD-7 |
