Immunotherapy With Adaptive Pulse Radiotherapy in Solid Tumors
Sponsor: Samsung Medical Center
Summary
The goal of this clinical trial is to find out whether Adaptive Pulse Radiotherapy (Pulse RT) combined with immune checkpoint inhibitors (ICIs) helps treat advanced solid tumors. It will also check how safe this combined treatment is and how it affects the immune system and quality of life. The main questions the study will try to answer are: Does adding Pulse RT to ICIs improve tumor response and survival? What side effects occur when participants receive Pulse RT with ICIs? How does the treatment change immune-related blood and tissue markers? Does the treatment affect participants' quality of life? Researchers will compare this new approach to usual ICI treatment to see whether Pulse RT makes a difference. Participants will: Continue to receive their standard ICI treatment. Receive 2-3 sessions of high-dose Pulse RT (8-10 Gy each) given about every 3 weeks. Have the treatment volume adjusted based on how their tumors respond. Visit the clinic regularly for check-ups, imaging, blood tests, and quality-of-life questionnaires.

Pulse radiation therapy
Adaptive Pulse Radiotherapy (Pulse RT) is a personalized radiotherapy strategy designed to enhance anti-tumor immunity when combined with immune checkpoint inhibitors (ICIs). Patients receive 2-3 fractions of 8-10 Gy at 3-4-week intervals, with adaptive modification of target volumes according to tumor response. This approach aims to induce repeated immunogenic cell death and expand tumor-specific T-cell repertoires, thereby amplifying the efficacy of concurrent immunotherapy while maintaining safety within standard dose constraints. Both photon and proton modalities may be used, depending on lesion location and clinical judgment.
