Detailed Description

This clinical study is a real-world exploratory study to observe the safety and initial effectiveness of DC-CTL cells combined with conventional anti-tumor therapy in patients with colorectal cancer, esophageal cancer, lung cancer, liver cancer, breast cancer and other solid tumors. In this study, DC-CTL cells were injected once a day for two consecutive days, 1-2 days after study participants received a conventional antitumor regimen, and subcutaneous injections of DC cells were administered before a second infusion of DC-CTL cells. A total of about 4-6 cycles of cell infusion are required, and the specific number of infusion and the composition of the peptide pool are determined by the investigator based on clinical needs and test results. After the cells have been transfused, their safety is examined first, and their effectiveness is evaluated during follow-up. According to the needs, this study plans to enroll about 20-200 patients with solid tumors such as colorectal cancer, esophageal cancer, lung cancer, liver cancer, and breast cancer. If the disease progresses during treatment, it is evaluated comprehensively by the investigator according to the clinical situation to determine whether the patient can be withdrawn from the study. Study participants in the follow-up phase who develop disease progression, begin other anti-tumor therapy without reaching disease progression after infusion, and voluntarily request to withdraw from the follow-up phase will be withdrawn from the follow-up phase and will be followed for survival only.

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.

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.

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.
