Phase 1
Recruiting
Led By Randa Tao, MD
Research Sponsored by University of Utah

Timeline
Screening 3 weeks

Follow Up 30 days after last study therapy
Awards & highlights
No Placebo-Only Group

Summary

This trial is testing whether a higher dose of radiation therapy, based on levels of tumor hypoxia, is safe.

Who is the study for?
This trial is for adults with esophageal cancer who can undergo chemoradiation therapy (CRT). They should be able to consent, have an ECOG Performance Status ≤ 2, and may include Stage IV patients with limited metastases if CRT is advised. Women must not be pregnant or must be post-menopausal.
What is being tested?
The trial tests personalized radiation therapy guided by hypoxia levels in tumors identified using FMISO PET CT and MRI scans. Patients with hypoxic tumors will receive higher radiation doses while others follow standard care. An interim MRI determines further treatment adjustments.
What are the potential side effects?
Potential side effects include those typically associated with radiation therapy such as skin irritation, fatigue, difficulty swallowing, nausea, and potential increased risk of secondary cancers long-term. Specific side effects from the imaging agents used could also occur.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
frequency of adverse events (AEs) and serious adverse events (SAEs) characterized by type, severity (as defined by the NIH CTCAE, version 5.0), seriousness, duration, and relationship to study treatment
rate of grade ≥ 4 esophageal adverse events attributed to radiation therapy that occur within 30 days of finishing radiation therapy
rate of grade ≥ 4 esophageal adverse events attributed to radiation therapy that occur within 84 days of finishing radiation therapy
Secondary study objectives
Pathological complete response (pCR) rate
Progression-free survival (PFS)
