A Phase II Study Evaluating the Combination of Neratinib Plus Trastuzumab or Neratinib Plus Cetuximab in Patients with "Quadruple Wild-Type" KRAS/NRAS/BRAF/PIK3CA Wild-Type) Metastatic Colorectal Cancer Based on HER2 Status: Amplified, Non-Amplified (Wild-Type) or Mutated
The primary aim of this study is to determine the progression-free survival (PFS) in each of these HER2 populations. Secondary aims include overall response rate (ORR) and clinical benefit rate (CBR) defined as the objective tumor decrease and stable disease by RECIST 1.1 criteria; toxicity and safety profile. Exploratory analysis will be performed to assess for molecular predictors of response. The local site will make the primary determination of response and progression based on all radiographic images (e.g., MRI, CT, PET, bone scan, etc.) as well as other relevant reports documenting disease response or progression.
For patients identified as quadruple WT with prior cetuximab or panitumumab treatment, a pre-entry blood sample will be required from consenting patients to confirm HER2 amplification for study eligibility.
