Official title:
LEEOMIC: CompLEEment-1 Canadian Correlative Sub-Study Comprehensive Proteomic Analysis Towards Discovery of Predictive Patterns of Protein Expression to Ribociclib Sensitivity and Resistance
Collection of tumor and blood samples from subjects enrolled in the main study (LEE011A2404) will undergo proteomic and ctDNA analysis respectively to better understand mechanisms of response and resistance to ribociclib in combination with letrozole therapy.
This is a sub-study of a phase IIIb interventional study (LEE011A2404). It cannot stand alone without the parent study. ;
