Brief Summary
The purpose of this study is to find out whether treatment with trastuzumab combined with pembrolizumab will improve the clearance of tumor DNA from participants' bodies after surgery.

Outcome Measures
Primary Outcomes (1)
Rate of ctDNA Clearance at 6 Months
The primary endpoint of the study is the proportion of patients with ctDNA clearance at 6 months with trastuzumab/pembrolizumab or trastuzumab/placebo in patients with HER2+ esophagogastric cancer with persistent ctDNA despite curative surgery and standard perioperative/adjuvant therapy. CtDNA clearance is the conversion of detectable to undetectable ctDNA
6 months
Study Arms (1)
Trastuzumab and Pembrolizumab
EXPERIMENTALTrastuzumab will be administered on an every 3 week dosing schedule, with initial loading dose of 8 mg/kg as a 90 minute infusion, followed by trastuzumab 6 mg/kg every 3 weeks. The planned dose of pembrolizumab for this study is 200 mg every 3 weeks.
Interventions
Trastuzumab (8mg/kg loading dose; 6mg/kg maintenance) will be administered on day 1 of each 3-week dosing cycle (21 days).
Pembrolizumab 200 mg IV will be administered on day 1 of each 3-week dosing cycle (21 days).
Eligibility Criteria
You may qualify if:
- Age 18 years or older.
- ECOG performance status 0-2.
- Sign informed consent within 8 months after curative surgery and completion of standard of care perioperative and/or adjuvant therapy.
- HER2+ esophageal, GEJ, or gastric adenocarcinoma biopsy or resection specimen as defined by local HER2 IHC3+ or IHC 2+/FISH\>2.0 expression.
- Must have genetic testing of DNA from primary tumor for somatic genomic alterations across a minimum of 50 genes.
- Must have undergone a complete curative surgical resection (R0).
- Must have completed standard of care (SOC) surgery, neoadjuvant or adjuvant therapy
- CtDNA will be tested at a minimum of four weeks after completion of surgery and standard perioperative and/or adjuvant therapy. To be eligible for trastuzumab/pembrolizumab or trastuzumab therapy, the patients must have positive ctDNA (as defined in section 7.0) within 8 months after completion of appropriate standard of care therapy (surgery, chemotherapy, radiation as appropriate). For all patients, if the initial ctDNA has a negative result, ctDNA can be re-tested 4 weeks later, within 9 months of completion of standard therapy.
- Demonstrate adequate organ function as defined in Table 1.
- Hematological Absolute neutrophil Count (ANC): ≥ 1,500 /mcL Platelets: ≥ 100,000 /mcL Hemoglobin: ≥ 9 g/dL
- Renal Serum creatinine ≤ 1.5 X upper limit of normal (ULN)
- Hepatic Serum total bilirubin ≤ 1.5 X ULN OR Direct bilirubin ≤ ULN for subjects with total bilirubin levels \> 1.5 ULN. Except patients with Gilbert's disease (≤ 3 x ULN) AST and ALT ≤ 2.5 X ULN Albumin ≥ 3 mg/dL
You may not qualify if:
- Patients who have not recovered from serious adverse events (as determined by treating MD) related to surgery.
- Presence of metastatic or recurrent disease.
- Had R1 (microscopic residual tumor) or R2 resection (macroscopic residual tumor at resection margin).
- Left ventricular ejection fraction \<50% within 1 month of screening by MUGA or echocardiogram.
- Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment.
- Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment.
- Patients who have received acute, low dose, systemic immunosuppressant medications (e.g., dexamethasone containing antiemetic regimen or steroids as CT scan contrast premedication) may be enrolled.
- The use of inhaled corticosteroids and mineralocorticoids (e.g., fludrocortisone) for patients with orthostatic hypotension or adrenocortical insufficiency is allowed.
- Has a known history of active TB (Bacillus tuberculosis)
- Hypersensitivity to pembrolizumab or any of its excipients.
- Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent.
- ° Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
- Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis
- Has known history of, or any evidence of active, non-infectious pneumonitis.
- Has an active infection requiring systemic therapy.
