Brief Summary:

This is a single-center, single-arm, open-label, Simon 2-stage, phase II trial in up to 55 patients with a potentially resectable, histologically-proven, adenocarcinoma or poorly differentiated carcinoma of the stomach, esophagogastric junction (EGJ), or lower third of the esophagus.

Patients will receive neoadjuvant therapy consisting of 4 cycles of avelumab added to the modified chemotherapy regimen of docetaxel, cisplatin, 5- fluorouracil. Following surgery, pathologic response will be assessed. Patients will then receive adjuvant therapy consisting of 4 cycles of mDCF + avelumab. Patients will be followed to assess two-year disease-free survival rates.

The primary objective of this study is to assess the effect on pathologic complete response rate (pCR) of adding avelumab to an mDCF regimen. The secondary objectives of this study are to determine the safety of adding avelumab to an mDCF regimen and assess its effect on two-year disease-free survival.

Arm Intervention/treatment
Experimental: mDCF + Avelumab

Patients will receive neoadjuvant therapy consisting of 4 cycles of avelumab added to the modified chemotherapy regimen of docetaxel, cisplatin, 5-fluorouracil, followed by surgery and assessment of pathologic response. Then they will receive 4 cycles of adjuvant therapy of docetaxel, cisplatin, 5-fluorouracil and avelumab.

Docetaxel as a one-hour 40 mg/m2 IV infusion on day 1. Cisplatin 40 mg/m2 IV infusion on day 1. 5-FU 1000 mg/m2/day over 2 days. Avelumab 10 mg/kg following the completion of the mDCF regimen.

Drug: mDCF + Avelumab
Patients will receive neoadjuvant therapy consisting of 4 cycles of avelumab added to the modified chemotherapy regimen of docetaxel, cisplatin, 5-fluorouracil (mDCF), followed by surgery and assessment of pathologic response. Then they will receive 4 cycles of adjuvant therapy of mDCF and avelumab.




Primary Outcome Measures :
  1. Pathologic Complete Response (pCR) [ Time Frame: 30±4 weeks ]
    Assessment of the pathologic complete response (pCR) rate after preoperative (neoadjuvant) treatment. pCR has been shown to correlate with long-term outcomes.For the purpose of this study, pCR is considered to represent grade 0 and grade 1 responses, defined by the criteria of the College of American Pathologists.


Secondary Outcome Measures :
  1. Two-Year Disease Free Survival (DFS) [ Time Frame: 104 weeks ]
    Analysis of two-year disease-free survival (DFS) following treatment.

  2. Safety Assessment of Adding Avelumab to mDCF [ Time Frame: 104 weeks ]
    Measurement of the incidence of grade 3 or 4 avelumab-related adverse events following treatment.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Signed, informed consent;
  2. Age 18 years or older;
  3. Histological diagnosis of adenocarcinoma or poorly differentiated carcinoma of the stomach, esophagogastric junction (EGJ), or lower third of the esophagus;
  4. The tumour must be deemed by the team to be potentially resectable. This includes imaging studies (detailed below) to clinically stage the tumor and rule out the presence of metastatic disease, and includes a preoperative laparoscopic evaluation for gastric tumors only;
  5. Stage IB (TlNl only), II, IHA, IIIB;
  6. Life expectancy greater than 3 months;
  7. ECOG performance status of 0-1;
  8. Neutrophils ~ 1500/μL;
  9. Platelet count~ 100,000/μL;
  10. Hemoglobin~ 9 g/dL;
  11. Total bilirubin level :S 1.5 x the upper limit of normal (ULN) range unless consistent with Gilbert's syndrome (normal direct bilirubin);
  12. AST and ALT :S 2.5 x ULN;
  13. If serum creatinine above upper limit of normal (ULN), creatinine clearance ~ 60 ml/min as determined by 24-h creatinine clearance or Cockcroft-Gault formula;
  14. Negative pregnancy test for women of child-bearing potential; and
  15. Highly effective contraception for both male and female subjects throughout the study and for at least 60 days after last avelumab treatment administration if the risk of conception exists.

Exclusion Criteria:

  1. Current or prior use of immunosuppressive medication, including corticosteroids, within 7 days prior to registration EXCEPT for the following:

    1. intranasal, intra-ocular, inhaled, topical steroids, or local steroid injection (e.g., intraarticular injection);
    2. Systemic corticosteroids at physiologic doses :S 10 mg/day of prednisone or equivalent;
    3. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication);
  2. Active autoimmune disease that might deteriorate when receiving an immuno-stimulatory agent. However, patients with diabetes type I, vitiligo, psoriasis, hypo- or hyperthyroid disease not requiring immunosuppressive treatment are eligible;
  3. Prior organ transplantation, including allogeneic stem cell transplantation;
  4. Squamous-cell carcinoma diagnosis;
  5. Significant acute or chronic active infections requiring systemic therapy, including, among others:

    1. Known history of testing positive test for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS);

  6. Vaccination with live vaccines within 4 weeks of the first dose of avelumab and while on trial;

  11. Other severe acute or chronic medical conditions including colitis, inflammatory bowel disease, pneumonitis, pulmonary fibrosis or psychiatric conditions including recent (within the past year) or active suicidal ideation or behavior; or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study;
  12. Known alcohol or drug abuse;
  13. Prior systemic therapy for gastric cancer;
  14. Prior exposure to antibodies directed at PD-1, PD-L 1, CTLA 4 antigens;

  18. Significant hearing impairment, as judged by the need for or use of a hearing aid. If there is any uncertainty regarding the degree of hearing impairment, an audiogram will be done. If the audiogram is grossly normal or shows only minor hearing impairment (i.e. not requiring hearing aid), the patient may be enrolled;
  19. Unwillingness to undergo investigations and/or treatment as outlined on the study; or
  20. Participation to another trial where an investigational drug is being used.
  21. History of another malignancy requiring treatment within the last 3 years. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin treated curatively and in-situ cervical cancer.
