Inclution Criteria
Inclusion Criteria:
1. Able to provide written informed consent and can understand and agree to comply with
the requirements of the study and the schedule of assessments
2. Age ≥ 18 years on the day of signing the informed consent form (or the legal age of
consent in the jurisdiction in which the study is taking place)
3. Able to provide blood and tumor tissue (for archival tumor tissue: formalin-fixed
paraffin-embedded [FFPE] blocks or at least 12 unstained FFPE tumor specimen slides
for retrospective confirmation of HER2 status and/or other biomarker analysis). Note:
Patients may be permitted to be enrolled on a case-by-case basis after discussion with the
sponsor’s medical monitor if fewer than 12 unstained slides are provided.
a. Patients who have no archival tumor tissue available must consent to provide fresh
biopsy samples before receiving treatment, unless previously discussed with
sponsor’s medical monitor.
4. Disease diagnosis and prior treatment:
a. Cohort 1 (the first-line breast cancer treatment cohort):
-Female patients with histologically or cytologically confirmed unresectable,
locally advanced, recurrent or metastatic adenocarcinoma of the breast and
candidate for chemotherapy. Locally recurrent disease must not be amenable to
resection with curative intent.
-HER2 IHC 3+ or in situ hybridization positive on the archival tumor tissue or
fresh biopsy sample. The most recently collected tissues are required if
applicable. For patients who had anti-HER2 therapy in neoadjuvant or adjuvant
setting, tumor tissue sample collected after completion of any prior anti-HER2
therapy is preferred. HER2 status determined (see details in Appendix 11) in the
investigational site is acceptable. If HER2 status cannot be acquired in the
investigational site, HER2 positivity must be confirmed in the sponsor designated
central laboratory as study entry eligibility.
-Have not received previous systemic anticancer therapy for locally advanced
unresectable or metastatic disease (with the exception of one prior hormonal
regimen for metastatic breast cancer which must be stopped with at least 14 days
of washout period), including any approved or investigational EGFR or anti-HER2
agents or vaccines, cytotoxic chemotherapy, antibody drug conjugate, checkpoint
inhibitors, or more than one prior hormonal regimen for metastatic breast cancer.
If a patient receives hormonal therapy for metastatic breast cancer and is switched
to a different hormonal therapy due to disease progression, this will be counted as
two “regimens” and the patient is not eligible.
Note: Prior systemic treatment in neoadjuvant or adjuvant setting is permitted if
the disease-free interval from completion of the systemic treatment (excluding
hormonal therapy) to diagnosis of locally advanced recurrent or metastatic disease
is ≥ 12 months. Prior trastuzumab with or without pertuzumab used in
neoadjuvant or adjuvant setting is permitted.
b. Cohort 2 (the first-line gastric/gastroesophageal junction adenocarcinoma
treatment cohort):
-Histologically or cytologically confirmed unresectable, locally advanced,
recurrent or metastatic adenocarcinoma of the stomach or gastroesophageal
junction
-HER2 IHC 3+ or HER2 IHC 2+ together with in situ hybridization positive on the
archival tumor tissue or fresh biopsy sample. The most recently collected tissues
are required if applicable. HER2 status determined (see details in Appendix 11) in
the investigational site is acceptable. If HER2 status cannot be acquired in the
investigational site, HER2 positivity must be confirmed in the sponsor designated
central laboratory as study entry eligibility.
-Have not received previous systemic anticancer therapy for locally advanced
unresectable or metastatic disease, including any approved or investigational
EGFR or anti-HER2 agents or vaccines, cytotoxic chemotherapy or checkpoint
inhibitors
Note: Prior systemic treatment in neoadjuvant or adjuvant setting will be
permitted if the disease-free interval from completion of the systemic treatment to
diagnosis of locally advanced recurrent or metastatic disease is longer than 6
months. Prior use of trastuzumab and/or pertuzumab is not allowed.
