Bu çalışma, HER2 pozitif yemek borusu ve mide kanseri (esophagogastric cancer) olan kişilerde Pembrolizumab, Trastuzumab ve kemoterapinin birlikte kullanımını değerlendirmektedir. Çalışmaya 18 yaş ve üzeri, tümörü tamamen ameliyatla çıkarılabilir, HER2 pozitif hastalar katılabilmektedir. Faz 2 aşamasında yürütülmekte ve halen katılımcı almaktadır.

Exclusion Criteria: * Presence of metastatic or recurrent disease. * Has received prior treatment for esophagogastric cancer * Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-CTLA-4 agent. * Has received prior therapy with an anti-HER2 agent * Left ventricular ejection fraction \<50% within 1 month of screening by MUGA or echocardiogram. Patients with an ejection fraction 45-49% may be permissible in the absence of any cardiac symptoms, if cleared by a cardiologist, and per the investigator's discresion. * 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 been diagnosed or treated for another malignancy in the past 3 years (not including non-melanoma skin cancer) * 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. * Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator. * Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial. * Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment. * A WOCBP who has a positive urine pregnancy test within 72 hours prior to allocation. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. * Has had an allogeneic tissue or solid organ transplant * Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease; systemic lupus erythematosus; Wegener syndrome \[granulomatosis with polyangiitis\]; myasthenia gravis; Graves' disease; rheumatoid arthritis, hypophysitis, uveitis) within the past 3 years prior to the start of treatment. The following are exceptions to this criterion: * Subjects with vitiligo or alopecia * Subjects with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement or psoriasis not requiring systemic treatment. * Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies). * Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA \[qualitative\] is detected). * Has received a live vaccine within 30 days of planned start of study therapy. Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines, and are not allowed. * Is unwilling to give written informed consent, unwilling to participate, or unable to comply with the protocol for the duration of the study.
