Trial summary

The purpose of this research study is to determine if radiation using proton beam therapy will kill the germ cell tumor in the participant's central nervous system. This type of radiation has been used previously on many patients with different types of cancers. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 3 to 25 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Histologically confirmed germ cell tumor or elevated AFP or B-HCG in the setting of radiographic disease consistent with a germ cell tumor. Disease must be confined to the central nervous system.
  • Participants do not need to have measurable disease. Most patients will not have measurable disease at the time of treatment.
  • 3 years of age or older and 25 years of age or younger at the time of diagnosis because this study evaluates this disease entity in the pediatric population which may differ from the adult population.
  • Life expectancy of greater than 12 months.
  • ECOG performance status of 0, 1 or 2
  • Baseline MRI of the brain and spinal axis with gadolinium and prior to any chemotherapy is required. If surgical resection is performed a post-operative MRI is required. If the patient receives chemotherapy prior to radiation, a post-chemotherapy MRI of the brain is required. If spinal involvement was seen on initial MRI and prior to chemotherapy, a MRI of the spine is required after chemotherapy and prior to radiation.
  • Serum and lumbar CSF must be obtained to evaluate for alpha fetoprotein (AFP) and beta human chorionic gonadotropin (HCG). This is needed to stratify patients into pure GCT and NGGCT.
  • Women of child-bearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation.

Who cannot join

  • Patients will be ineligible if any prior therapeutic radiation therapy > 200 cGy has been delivered to the central nervous system.
  • Patients will be ineligible if chemotherapy was completed greater than 1 year from the planned start date of radiation therapy or if the patient is referred for radiation therapy after a relapse following a regimen with chemotherapy alone.
  • Individuals with a history of a different malignancy are ineligible except for the following circumstances: Disease-free for at least 5 years and are deemed by the investigator to be at low risk for recurrence of that malignancy. Individuals diagnosed and treated within the past 5 years for cervical cancer in situ and basal cell or squamous cell carcinoma of the skin.
  • Pregnant females

About this study

Official title: Phase II Study of Proton Radiation Therapy for CNS Germ Cell Tumors: Evaluation of Acute and Late Side Effects

The purpose of this research study is to determine if radiation using proton beam therapy will kill the germ cell tumor in the participant's central nervous system. This type of radiation has been used previously on many patients with different types of cancers. There are two types of external radiation treatments, proton beam and photon beam. In this study we will be examining the effects of proton beam radiation therapy. Studies have suggested that this kind of radiation can spare normal tissue more than photon radiation therapy. The physical characteristics of proton beam radiation let the doctor safely increase the amount of radiation delivered to the tumor. We believe that proton beam therapy will potentially reduce side effects that participants would normally experience with photon radiation therapy.

Read the detailed description
  • Before participants begin radiation therapy they will have scans done to prepare them for radiation treatment. Doctors will use the information gathered from these scans to plan the best way to deliver radiation to the tumor.
  • Participants will receive treatment as an outpatient at the Francis H. Burr Proton Center located at the Massachusetts General Hospital.
  • Not everyone who participates in this study will receive the same amount of proton radiation therapy. The length of time and amount of radiation that the participant will receive will depend on the type of germ cell tumor they have and the stage of the their disease.
  • Radiation treatment will be given once a day, 5 days a week (Monday-Friday), for 4-8 weeks depending on the condition of the participant's disease.
  • During each week of proton radiation therapy, participants will have a physical exam and be asked questions about their general health and any problems they might be experiencing.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To describe late complications of craniospinal, whole ventricle, and involved field radiation therapy delivered with proton radiotherapy in place of photon radiation for this patient population.

    Measured: 2 years

  2. To evaluate acute and subacute toxicities of craniospinal, whole ventricle, and involved field radiation therapy delivered with proton radiotherapy in place of photon radiation in this patient population.

    Measured: 2 years

Secondary outcomes (1)
  1. To determine 3 year progression free survival rate of patients with pure germ cell tumors and non-germinomatous germ cell tumors treated with proton radiation.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A study testing Proton Beam radiation in people with Germ Cell Tumor and Central Nervous System Germ Cell Tumor, run by Massachusetts General Hospital at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 29 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To describe late complications of craniospinal, whole ventricle, and involved field radiation therapy delivered with proton radiotherapy in place of photon radiation for this patient population. (time frame: 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2026; AzTrials last refreshed its copy on 6 Nov 2026.
