Methotrexate Combined With Immunotherapy During Radiotherapy for Solid Tumors

October 22, 2024 updated by: Wei Geng, Yancheng First People's Hospital

Safety and Efficacy of Oral Methotrexate Tablets Combined With Immunotherapy During Radiotherapy for Unresectable/Metastatic Solid Tumors: a Single-center, Prospective Study

Immune checkpoint inhibitors, such as programmed death 1 (PD-1) and programmed cell death-Ligand 1 (PD-L1), offer new approaches for systemic treatment of tumors, but clinical efficacy remains limited. Previous studies by our team have found that methotrexate can activate anti-tumor immunity. The discovery of a new effect of this drug will improve tumor response to immunotherapy and prognosis of patients.

Study Overview

Status

Status

Active, not recruiting

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Malignant tumor is a systemic and complex disease that seriously endangers human health, surgery is the preferred treatment for solid tumors. Due to the extensive invasion and metastasis of advanced tumors, radiotherapy and chemotherapy are the main treatment options. However, the tolerance of tumor to chemoradiotherapy often leads to treatment failure and poor prognosis. Immunotherapy provides a new approach for the systemic treatment of tumors, but the clinical efficacy is still limited. Therefore, it is important to find effective drugs to improve the tumor response to radiotherapy and immunotherapy. Previous studies by our team have found that methotrexate can activate anti-tumor immunity. The discovery of a new effect of this drug will improve tumor response to immunotherapy and prognosis of patients. The objective of this clinical trial is to explore the efficacy and safety of methotrexate combined with immunotherapy and radiotherapy in patients with unresectable/recurrence solid tumors.

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

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

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.

Treatment-related adverse events (AEs)
Time Frame: Up to 6 months

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.
