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

EXPERIMENTAL

Trastuzumab 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.

Drug: TrastuzumabDrug: Pembrolizumab

Interventions

Trastuzumab (8mg/kg loading dose; 6mg/kg maintenance) will be administered on day 1 of each 3-week dosing cycle (21 days).

Trastuzumab and Pembrolizumab

Pembrolizumab 200 mg IV will be administered on day 1 of each 3-week dosing cycle (21 days).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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.
  • +12 more criteria
