Exclusion Criteria:

- Tumors with significant involvement of the proximal stomach which, in the opinion of
the treating thoracic surgeon, would require an esophagogastrectomy
- Patients with evidence of metastatic disease, including:
- Positive malignant cytology of the pleural, pericardium or peritoneum
- Radiographic evidence of distant organ involvement
- Non-regional lymph nodes that cannot be contained within a radiation field
- Biopsy-proven tumor invasion of the tracheobronchial tree or presence of
tracheoesophageal fistula. Recurrent laryngeal or phrenic nerve paralysis
- Grade 2 = peripheral neuropathy
- 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
- History of pneumonitis
- The use of immunosuppressive medication within 28 days prior to the first dose of
durvalumab-/tremelimumab. The following are exceptions to this criterion:
- Intranasal, topical, inhaled corticosteroids or local steroid injections (e.g.
intraarticular injection)
- Systemic corticosteroids at physiologic doses =10 mg/day of prednisone or
equivalent
- Steroids as premedication for hypersensitivity reactions (e.g. CT scan
premedication)
- Known HIV positivity
- Chronic Hepatitis B or known Hepatitis C infection (e.g. Hepatitis B surface Ag
positive or detectable viral load for Hepatitis B). Patients with prior evidence of
Hepatitis B or C without active infection are eligible
- Known history of previous clinical diagnosis of tuberculosis
- Uncontrolled seizures
- Pregnant or breast-feeding women. Women of childbearing potential (WOCBP) must undergo
a negative pregnancy test (either serum or urine) prior to study entry. Male and
female patients of reproductive potential need to employ two highly effective and
acceptable forms of contraception throughout their participation in the study and for
90 days after last dose of study drug. WOCBP include:
- Any woman who has experienced menarche and who has not undergone surgical
sterilization (hysterectomy, bilateral tubal ligation or oophorectomy) or who is
not post-menopausal (defined as amenorrheic =12 consecutive months)
- Women on hormone replacement therapy with documented serum follicle stimulating
hormone level > 35 mIU/ml
- Women who are using oral, implanted or injectable contraceptive hormones or
mechanical products such as intrauterine device or barrier methods to prevent
pregnancy or are practicing abstinence of where the partner is sterile
- Prior malignancy (other than basal cell/squamous cell carcinoma of the skin, in-situ
cervical carcinoma or superficial transitional cell bladder carcinoma) diagnosed
and/or treated within three years of study entry
- Connective tissue disorders, e.g. scleroderma, that in the opinion of the treating
physicians is a contraindication to radiation therapy
- History of primary immunodeficiency
- History of allogenic organ transplant
- Receipt of live attenuated vaccination within 30 days prior to study entry or within
30 days of receiving durvalumab. For example, the intramuscular influenza vaccine can
be administered but the intranasal vaccine is a live attenuated virus that cannot be
given
- Any previous treatment with a PD-1 or PD-L1 inhibitor, including durvalumab, or a
CTLA-4 inhibitor, including tremelimumab.
- History of hypersensitivity to durvalumab or tremelimumab or any excipient
Uncontrolled intercurrent illness including but not limited to, ongoing or active
infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable
angina pectoris, cardiac arrhythmia, active peptic ulcer disease, active bleeding
diatheses or psychiatric illness/social situations that would limit compliance with
study requirements or compromise the ability of the subject to give written informed
consent
