Safety and Efficacy of Radiotherapy Combined with Immunotherapy for Advanced Malignant Tumors.

February 25, 2025 updated by: Guangying Zhu, China-Japan Friendship Hospital

A Prospective Clinical Trial Evaluating the Safety and Efficacy of Radiotherapy Combined with Immunotherapy in Advanced Refractory Solid Malignancies After Standard Treatment Failure/drug Resistance.

The goal of this clinical trial is to find a new radioimmunotherapy regimen for advanced malignancies with multiple metastatic after standard treatment failure/drug resistance. The main questions it aims to answer is: the safety and efficacy of the new regimen for advanced multiple metastatic solid tumors standard treatment failure/drug resistance, and explore the impact on immune function. Participants will receive the combination of radiotherapy and immunotherapy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

More effective treatment regimens remain to be explored for advanced malignancies with multiple metastatic after standard treatment failure/drug resistance. The combination of radiotherapy and immunotherapy is considered to be a promising therapeutic strategy. Studies showed the efficacy of PRaG (PD-1 inhibitor, Radiotherapy and GM-CSF) treatment and stereotactic radiotherapy (SBRT) combined with low-dose radiotherapy (LDRT) for advanced tumors. Therefore, the investigators designed a new radioimmunotherapy regimen, including SBRT, LDRT , PD-1/PD-L1 inhibitor, and GM-CSF. This study aimed to evaluate the safety and efficacy of the new regimen for advanced multiple metastatic solid tumors standard treatment failure/drug resistance, and explore the impact on immune function.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No
