Clinical Trial Summary

Rates of local disease control in patients with locally advanced esophageal cancer who are not candidates for surgical resection are suboptimal. Despite treatment with chemotherapy and radiation therapy approximately half of patients will develop recurrence of their cancer at the site of the original primary cancer. Salvage therapy options are largely ineffective and nearly all patients who develop local disease recurrence will succumb to their cancer. Recent clinical trials for lung cancer have demonstrated that local tumor control can be improved safely with accelerated hypofractionated radiation therapy regimens in order to achieve radiation dose intensification. This clinical trial aims to adapt those techniques and assess the safety of such a regimen for the treatment of inoperable thoracic esophageal cancers.

• Chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of registration.
• Peripheral neuropathy > grade 1 at time of registration.
• Persistent complications from any major surgery within 4 weeks of study treatment start.
• Any other major medical illness that in the investigator's opinion would prevent safe administration or completion of protocol therapy.
• Pregnant or lactating woman. Women of childbearing potential with positive pregnancy test at baseline, or women who have not taken a pregnancy test at baseline. A man or woman who does not agree to use appropriate contraception.
• Patients with HIV are eligible unless their CD4+ T-cell counts are < 350 cells/mcL or they have a history of AIDS-defining opportunistic infection within the 12 months prior to registration. Concurrent treatment with effective ART according to DHHS treatment guidelines is recommended.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum tolerated dose (MTD) of hypofractionated IMRT with chemotherapy	The MTD of the combination of radiation and FOLFOX will be estimated using the proposed TITE-CRM model. After the phase I study, the MTD will be chosen as the dose that yields a posterior toxicity estimate closest to 20% while being between 15% and 25%. Toxicity will be coded using CTCAE v5.0.	Through 6 month follow-up for all enrolled patients (estimated to be 65 months)
Secondary	Median local relapse-free survival	-The length of time after treatment ends that the participants survives without any signs or symptoms of the cancer recurring within the radiated field	24 months
Secondary	Median overall survival	-The length of time from the start of treatment that participants are still alive	24 months
Secondary	Median progression-free survival	-The length of time from the start of treatment to progression or death from any cause	24 months
Secondary	Patient reported outcomes as measured by the MDASI-Plus	The MDASI-plus is a reliable, validated tool for assessing cancer-related symptoms regardless of therapy or specific cancer diagnosis. Patients are asked to fill out a twenty-seven question inventory, ranking their symptoms on a 0 (no problems) to 10 (worst imaginable) scale; The mean of the scores will be calculated at each time point and compared to other time points to assess changes in cancer-related symptoms	From baseline through 12 months post end of treatment
Secondary	Patient reported outcomes as measured by the EQ-5D	standardized 2-part, patient-administered instrument used for direct and indirect assessment of health state utilities; The first part asks respondents to "check the ONE box [next to the appropriate statement] that best describes your health TODAY" for each of 5 health dimensions, including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The second part of the EQ-5D is a visual analogue scale (VAS) valuing current health state; Both the 5-item index score and the VAS score are transformed into a utility score between 0 "Worst health state" and 1 "Best health state	From baseline through 12 months post end of treatment
Secondary	Patient reported outcomes as measured by the SF-12	12-item questionnaire measuring physical and mental functional status; Mental and physical component scores will be calculated in addition to calculating the measure's eight individual subscales (physical functioning, social functioning, role limitations due to physical problems, body pain, general health, role limitations due to emotional problems general health, vitality, and mental health). Higher scores indicate better quality of life	From baseline through 12 months post end of treatment
Secondary	Patient reported outcomes as measured by the MOS Social Support	-19 items; -. Response choices range from "none of the time" (1) to "all of the time" (5). A mean social support score for all 19 items is computed with higher scores indicating a greater availability of social support.	From baseline through 12 months post end of treatment
Secondary	Patient reported outcomes as measured by the 4-Item CES-D	4 item screening version to evaluate depressive symptoms; The mean of the scores will be calculated at each time point and compared to other time points to assess changes in depression symptoms	From baseline through 12 months post end of treatment
Secondary	Number and type of adverse events experienced by patient		12 months
