A clinical study of patritumab deruxtecan in people with breast cancer
EU CTIS ID: 2024-514376-40-00
What this study is testing
1. Part 1 Objective: To evaluate safety and tolerability of neoadjuvant patritumab deruxtecan (HER3-DXd) plus pembrolizumab before carboplatin/ paclitaxel plus pembrolizumab. 2. Part 2 Objective: To compare HER3-DXd plus pembrolizumab before carboplatin/paclitaxel plus pembrolizumab versus carboplatin/paclitaxel plus pembrolizumab followed by AC/EC plus pembrolizumab with respect to rate of pCR (ypT0/Tis ypN0) at the time of definitive surgery, as assessed by local pathologist. 3. Part 2 Objective: To compare HER3-DXd plus pembrolizumab after carboplatin/paclitaxel plus pembrolizumab versus carboplatin/paclitaxel plus pembrolizumab followed by AC/EC plus pembrolizumab with respect to rate of pCR (ypT0/Tis ypN0) at the time of definitive surgery, as assessed by local pathologist. 4. Part 2: To evaluate safety and tolerability of study interventions in all arms.

Who can take part
You may be able to join if
- Has locally advanced, non-metastatic (M0), breast cancer, defined as any of the following combined primary tumor (T) and regional lymph node (N) staging per current American Joint Committee on Cancer (AJCC) criteria: cT1c, N1-N2; cT2, N0-N2; cT3, N0-N2; or cT4a-d, N0-N2
- Has centrally confirmed diagnosis of breast cancer that is triple-negative or HR-low+/HER2- breast cancer that will be treated according to the triple-negative breast cancer (TNBC) paradigm
- Participants who are Hepatitis B surface antigen (HBsAg) positive are eligible if they have received Hepatitis B virus (HBV) antiviral therapy for at least 4 weeks and have undetectable HBV viral load
- Participants with a history of Hepatitis C virus (HCV) infection are eligible if HCV viral load is undetectable
- Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 within 28 days prior to allocation/randomization
- Has left ventricular ejection fraction (LVEF) of ≥50% or ≥ lower limit of normal (LLN) as assessed by echocardiogram (ECHO) or multigate acquisition scan (MUGA) scan
You likely can't join if
- Has uncontrolled or significant cardiovascular disease before randomization
- Has a history of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease, or where suspected ILD/pneumonitis cannot be ruled out by standard diagnostic assessments
- Has an active infection requiring systemic therapy
- Has concurrent active HBV and HCV infection
- Has clinically severe respiratory compromise resulting from intercurrent pulmonary illness
- Has clinically significant corneal disease
