A Study of Intensity-Modulated Pleural Radiation Therapy (IMPRINT) in People With Thymic Cancer That Has Spread to the Lining of the Lungs and Chest

May 1, 2026 updated by: Memorial Sloan Kettering Cancer Center

Phase II Study of Hemithoracic Intensity-Modulated Pleural Radiation Therapy (IMPRINT) for Patients With Pleural Metastases From Thymic Malignancies

The researchers are doing this study to find out whether hemithoracic intensity-modulated pleural radiation therapy (IMPRINT) is a safe treatment that causes few or mild side effects in people with pleural metastases from thymic malignancies. The researchers will also look at whether hemithoracic IMPRINT is effective against participants' cancer.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Provide written informed consent to participate on the study
  • Patients must have a pathologically confirmed diagnosis of thymic malignancy. Thymic carcinoma is allowed.
  • Patients must have radiologic or pathologic evidence of pleural metastases. Patients may have de novo stage IVA or recurrent disease in the pleura. Gross disease in the fissure is allowed if resected.
  • No evidence of extrathoracic metastatic disease or contralateral pleural/pericardial disease.
  • Patient age ≥ 18 years but ≤ 80 years at the time of consent
  • Karnofsky performance status ≥ 80%
  • Preoperative or Postoperative Pulmonary Function Tests: DLCO > 40% predicted (corrected for Hgb) and FEV1 ≥ 35% (corrected for Hgb)
  • Glomerular filtration rate (GFR): ≥50 mL/min/1.73 m2 (must be calculated using estimated creatinine clearance (CrCl) by the Cockcroft-Gault (C-G) equation (Nephron 1976;16:31-41): CrCl (mL/min) = [140 - age (years)] x weight (kg) [x 0.85 for female patients] 72 x serum creatinine (mg / dL) ° In cases of concern about decreased renal function and potential high radiation dose to the kidneys, an optional nuclear medicine kidney function scan may be performed prior to radiation therapy to determine the functional contribution of each kidney.

Exclusion Criteria:

  • Continuous oxygen use
  • Patients with an acute flare of myasthenia gravis requiring addition of new medication in the past 6 months
  • Prior nephrectomy on the contralateral side of the pleural metastases
  • Prior thoracic radiation therapy preventing hemithoracic pleural IMRT. Prior thymic bed radiation is allowed. Prior pleural SBRT is allowed.
  • Patients undergoing extrapleural pneumonectomy. Other surgical resection approaches of the pleural nodules (ex: P/D, debulking/metastasectomy) are allowed. Surgical resection of the primary thymic tumor is allowed.
  • Acute congestive heart failure requiring hospitalization within the past 30 days.
  • COPD requiring chronic oral steroid therapy of > 10 mg prednisone daily or equivalent at the time of registration. Inhaled corticosteroids are allowed
  • Unstable angina requiring hospitalization and/or transmural myocardial infarction within the last 3 months
  • History of interstitial lung disease

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
assess the rate of radiation pneumonitis
Time Frame: 2 years
as indicated by the rate of grade 3 or higher radiation pneumonitis defined by the NCI Common Terminology Criteria (CTC) version 5.0.
2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
progression-free survival (PFS)
Time Frame: 12 month
PFS events will include death and/or progression of thymic malignancy due to local-regional or distant recurrence/progression. PFS will be calculated from the start of radiation treatment and will be estimated by the Kaplan-Meier method.
12 month
