Study type: Interventional What is this?
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
This pilot randomized clinical trial studies the effects, good and/or bad, of taking doxepin hydrochloride compared to placebo (inactive drug) in treating esophageal pain in patients with thoracic cancer receiving radiation therapy to the thorax with or without chemotherapy. Doxepin hydrochloride is a tricyclic antidepressant drug which was recently shown to be helpful for mouth pain in patients receiving radiation therapy. Part of doxepin hydrochloride's drug action takes place at the surface of the esophagus, which may be helpful in reducing the pain caused by radiation therapy.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
See eligibility criteria
- Histological confirmation of thoracic malignancies including non-small cell lung cancer (NSCLC), small lung cancer (SCLC), lymphoma, thymoma, thymic carcinoma, mesothelioma, sarcoma, and pulmonary or pleural-based metastases
- Planned RT (with or without chemotherapy) to a dose of ≥ 20 Gray (Gy) using 1.60 to 4.00 Gy per daily fraction; if radiation is given twice daily, a cumulative planned dose of ≥ 15 Gy using 1.25 to 2.75 Gy per fraction is required
- At least 5 cm of the esophagus must be planned to receive radiotherapy, with a minimum dose of at least 10 Gy
- ≥ 4 esophageal pain, either at rest or during swallowing, felt to be related to esophagitis for which the patient wants relief, as measured by asking the following question
- "On a scale of 0 to 10 (0 = no pain; 10 = worst pain), what number best describes your chest pain* (right now) due to your radiation treatment?"
- Radiation can cause inflammation in your esophagus which can feel like a chest pain, either at rest or during swallowing
- Able to swallow
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1, or 2
- Direct bilirubin < 2.0 x upper limit of normal (ULN)
- Aspartate transaminase (AST) ≤ 4 x ULN
- Negative pregnancy test done ≤ 28 days prior to registration, for women of childbearing potential only
- Ability to complete questionnaire(s) by themselves or with assistance
- Provide informed written consent
- Willingness to complete evaluation and questionnaires per protocol at the participating institution for follow-up (during the active monitoring phase of the study)
- Willing to provide blood samples for correlative research purposes

- Histologic proof of and getting treatment for esophageal, stomach, spinal cord, thyroid, breast, and head and neck cancers and vertebral metastases
- Use of a tricyclic antidepressant or monoamine oxidase inhibitor within the 2 weeks prior to registration
- The presence or strong clinical suspicion of a tracheoesophageal fistula, or known esophageal invasion by cancer
- Current untreated or unresolved esophageal candidiasis or herpes simplex virus (HSV) infection
- Current untreated narrow angle glaucoma
- Current untreated urinary retention ≤ 6 weeks prior to registration
- Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens
