   • Significant ventricular or supraventricular arrhythmias (Patients with chronic rate-controlled atrial fibrillation in the absence of other cardiac abnormalities are eligible).

Outcome Measure	Measure Description	Time Frame
Pathologic Complete Response (pCR) Rate in Patients Treated With ErC for 6 Cycles Prior to Surgery	One cycle = 21 days.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The Number of Adverse Events as a Measure of Safety and Tolerability.	Treatment-Related Adverse Events occurring in >= 15% of treated patients	43 months
Clinical Response Rate (cRR) of ErC as Neoadjuvant Therapy	Defined as the number of patients with a best response of clinical complete or partial response (cCR or cPR) divided by the number of patients qualified for tumor response analysis per Response Evaluation Criteria in Solid Tumors Criteria (RECIST) v1.1 for target lesions and assessed by MRI or CT. Complete Response (CR) defined as disappearance of all target lesions; Partial Response (PR) defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD;	43 months
