About this study
Official title: A Phase I/II Study of Combination of Proton Therapy With Immunotherapy in Multiple Metastases Cancer
The purpose of this research study is to compare the effects (good and bad) on subjects and their cancer using proton radiation therapy in combination with immunotherapy(ie. Programmed cell death protein 1, also known as PD-1 antibody) in multiple metastases.
Read the detailed description
As is known to all, the main treatment method for metastatic tumors is systemic chemotherapy and radiotherapy is merely for the purpose of palliative treatment. Recent studies have shown that tumors with no more than 5 metastatic sites can still achieve satisfactory overall survival by local treatments such as radiotherapy. However, for tumors with more metastatic lesions, side effect is pretty high for photon radiotherapy due to the wide range of irradiation. Protons might be a safe treatment means for multiple metastases cancer because of the Brag peak, when the normal tissue dose can be significantly reduced. Combination of proton therapy with immunotherapy can be a research direction for multiple metastatic tumors. This study intends to observe the safety and efficacy of proton technique combined with immunotherapy in improving the overall anti- tumor effect for metastatic tumors.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Radiation: Proton Therapy+PD-1 Ab in people with Proton Therapy and Immunotherapy, run by Peking University First Hospital.
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 6 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 5 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.
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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Yun Bai, MD ((+86)010 83575641, 08043@pkufh.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Adverse events (time frame: Through 1 years after completion of treatment). 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 5 Dec 2018; AzTrials last refreshed its copy on 8 Nov 2026.
