Improving Pre-operative Systemic Therapy for Human Epidermal Growth Factor Receptor 2 (HER2) Amplified Breast Cancer (PREDIXIIHER2)
Improving Pre-operative Systemic Therapy for Human Epidermal Growth Factor Receptor 2 (HER2) Amplified Breast Cancer Part of a Platform of Translational Phase II Trials Based on Molecular Subtypes
Study Overview
Status
Detailed Description
The primary aim is to investigate whether the rate of pCR, after optimal neoadjuvant anti-HER2 based systemic therapy, can be increased by addition of atezolizumab.
Secondary aims are to assess safety and tolerability of this treatment combination, and to identify therapy predictive factors for the anti-HER2 monoclonal antibodies trastuzumab and pertuzumab plus-minus atezolizumab with a backbone of chemotherapy, using modern molecular biological investigational procedures with analyses by repeated biopsies from an intra-patient longitudinal study design.

Symptoms using the Memorial Symptoms Assessment Scale (MSAS).
The 32-item MSAS scale includes occurrence, frequency, severity, and distress associated with each symptom using four- and five-point rating scales.

Higher scores indicates higher symptom burden.
