• Adequate normal organ and marrow function as defined below. Screening laboratory values must meet the following criteria and should be obtained within 28 days prior to registration WBC ≥ 1500/μL Neutrophils ≥ 1000/μL Platelets ≥ 75 x103/μL Hemoglobin > 9.0 g/dL Serum creatinine ≤ 1.5 x institutional ULN or calculated creatinine clearance (CrCl) ≥ 40 mL/min (Cockcroft-Gault)

Males:

Creatinine CL (mL/min) = Weight (kg) x (140 - Age) 72 x serum creatinine (mg/dL)

Females:

Creatinine CL (mL/min) = Weight (kg) x (140 - Age) x 0.85 72 x serum creatinine (mg/dL)

AST/ALT (SGOT/SGPT) ≤ 2,5 x institutional ULN Total Bilirubin ≤ 1.5 x institutional ULN (except study participants with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL)

• Body weight > 30kg
• Reproductive Status Women of childbearing potential (WOCBP) must use appropriate method(s) of contraception and must agree to use adequate method to avoid pregnancy for 5 months (30 days plus the time required for durvalumab to undergo five half-lives) after the last dose of study drug.

Appropriate methods of contraception are:

• female sterilization or tubal ligation (at least 6 weeks prior to the start of the study treatment),
• male sterilization (at least 6 months prior to the start of the study treatment) and/or
• a combination of a hormonal method of contraception with a barrier method or/and

• an intrauterine device or system

  • Women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of β-HCG) within one until two weeks prior to the start of durvalumab at time of neoadjuvant treatment and after surgery before starting adjuvant treatment.
  • Women will be not be considered to be of childbearing potential if they are post-menopausal and/or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy). To be considered post-menopausal the appropriate age-specific requirements have to be met:

Women < 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution.

Women ≥ 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses > 1 year ago.

• Women must not be breastfeeding.
• Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men receiving durvalumab and who are sexually active with WOCBP must be willing to adhere to contraception for a period of 7 month post treatment completion.
• Sexually active men receiving durvalumab must use a condom, even if vasectomized, to prevent delivery of the drug via seminal fluid.

Exclusion Criteria:

• Study participants with squamous cell carcinoma of the esophagus
• Prior treatment with chemotherapy, targeted therapy or radiotherapy for treatment of advanced cancer disease less than 5 years

• Enrollment is possible for patients with:

  • Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
  • Adequately treated carcinoma in situ without evidence of disease
• Any other serious or uncontrolled medical disorder, active infections, physical exam findings, laboratory finding, altered mental status, or psychiatric condition that, in the opinion of the investigator, would limit a study participant's ability to comply with the study requirements, substantially increase risk to the study participant, or impact the interpretability or study results
• Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc]). The following are exceptions to this criterion:

Patients with vitiligo or alopecia Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement Any chronic skin condition that does not require systemic therapy Patients without active autoimmune or inflammatory disease in the last 5 years may be included but only after consultation with study physician Patients with celiac disease controlled by diet alone. Inhaled or topical steroids and adrenal replacement steroid doses > 10mg daily prednisone equivalent are permitted in the absence of active autoimmune disease.

• History of active primary immunodeficiency
• History of any allogenic organ transplantation with currently intake of immune suppressive treatment
• Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice), hepatitis B (known positive HBV surface antigen (HBsAg) result), hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies). Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
• Patients with interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected drug-related pulmonary toxicity. FEV 1 < 75%
