Brief Summary
The purpose of this Phase I study is to determine the recommended phase 2 dose (RP2D) and safety profile of NBTXR3 activated by radiation therapy with concurrent chemotherapy for the treatment of patients with esophageal adenocarcinoma. NBTXR3 is a drug that when activated by radiation therapy, may cause targeted destruction of cancer cells. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as oxaliplatin, fluorouracil, capecitabine, docetaxel, paclitaxel, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving NBTXR3 activated by radiation therapy with concurrent chemotherapy may help control the disease.

Conditions
Outcome Measures
Primary Outcomes (2)
Incidence of dose limiting toxicities (DLTs)
Will be coded and graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5 criteria. Descriptive summary tables will be produced, providing the DLTs by initial planned dose level of NBTXR3, initial planned volume of NBTXR3 to be injected, the injected volume, the radiation therapy dose given and the details of the concurrent chemotherapy given.
Up to end of treatment visit (day 85)
Maximum tolerated dose and recommended phase 2 dose (RP2D)
The Bayesian Optimal Interval design, with accelerated titration, will be used to identify RP2D.
Up to end of treatment visit (day 85)
Secondary Outcomes (8)
Incidence of NBTXR3/radiation therapy related late onset toxicities
From end of treatment visit (day 85) until end of study (1 year)
Feasibility of NBTXR3 injection in the esophageal tumor and involved regional lymph nodes
Up to 1 year
Objective response rate
Up to 1 year
Major pathological response rate
Up to 1 year
Local progression-free survival
From NBTXR3 injection to locoregional (i.e., within the esophagus or regional nodes) disease recurrence, local progression confirmed radiographically (RECIST v1.1), or death from any cause, whichever occurs first, assessed up to 1 year
- +3 more secondary outcomes
Other Outcomes (11)
Time-course dependent presence of hafnium in blood and urine following NBTXR3 intratumoral/intranodal injection
Up to 4 hrs post NBTXR3 injection
Disease control rate
At 6 months post NBTXR3
R-status
Up to 1 year
- +8 more other outcomes
Study Arms (1)
Treatment (NBTXR3, IMRT, chemotherapy)
EXPERIMENTALPatients receive NBTXR3 IT or IN on day 1. Beginning day 15, patients undergo IMRT 5 days per week for 6 weeks for a total of 28 fractions, in the absence of disease progression or unacceptable toxicity. Concurrent with IMRT, patients receive a chemotherapy regimen consisting of either fluorouracil and oxaliplatin with or without leucovorin, oxaliplatin and capecitabine, docetaxel and fluorouracil with or without leucovorin, docetaxel and paclitaxel, or carboplatin and paclitaxel per physician discretion.

Eligibility Criteria
You may qualify if:
- Biopsy proven adenocarcinoma of the cervical or thoracic esophagus or gastroesophageal junction

- Carboplatin and paclitaxel
- Amenable to undergo the endoscopic ultrasound (EUS) guided injection of NBTXR3 as determined by the investigator or treating physician
- Patients with lesions for which the EUS scope is not able to traverse the tumor are allowed on this trial as long as an injection can be performed as per treating physician's discretion
- Has at least 1 and up to 4 target lesion(s) in the esophagus that are measurable on cross sectional imaging and repeated measurements (via Response Evaluation Criteria in Solid Tumors \[RECIST\] version \[v\] 1.1) at the same anatomical location should be achievable
- Local nodal disease around the esophagus allowed
- Nodal target lesions must be \>= 15 mm (short axis) based on computed tomography (CT) (slice thickness of 5 mm or less) or magnetic resonance imaging (MRI)
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- Hemoglobin \>= 8.0 g/dL
- Absolute neutrophil count (ANC) \>= 1,500/mm\^3

- +7 more criteria
You may not qualify if:

- Prior surgical resection of esophageal tumor
- Esophageal cancer with radiographic evidence of metastases at screening
- At screening, past medical history of:
- Esophageal fistula
- Tracheoesophageal fistula
- Siewert type III tumors
- Evidence of bulky disease and/or abutment of tumor above the carina that may result in tracheoesophageal fistulas as determined by the investigator or treating physician
- Tumors above the carina without defacement of the fat plane between tumor and the airway are allowed
- Known uncontrolled (grade \>= 2) or active esophageal or gastric ulcer disease within 28 days of enrollment
- Known contraindication to iodine-based or gadolinium-based intravenous (IV) contrast
- Active malignancy, in addition to esophageal cancer except for basal cell carcinoma of the skin or non-metastatic low risk prostate cancer definitively treated and relapse free within at least 3 months from time of screening
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, renal failure, cardiac arrhythmia, or psychiatric illness that would limit compliance with treatment
- Known active, uncontrolled (high viral load) human immunodeficiency virus (HIV) or hepatitis B or hepatitis C infection
