Patients voluntarily signed informed consent and expected compliance.
Exclusion Criteria:
Those meeting any of the following conditions may not be included.
- Known or suspected hypersensitivity to the ingredients of the study drug or its analogues;
- Patients with any other disease or medical condition that is unstable or may affect their safety or study compliance, any serious or uncontrolled systemic disease, including severe heart disease, cerebrovascular disease, uncontrolled diabetes, uncontrolled hypertension, active gastrointestinal ulcers, abnormal immune function, etc.;
Cardiovascular and cerebrovascular diseases/symptoms/indications that meet any of the following conditions:
- mean resting QTc > 470 ms (corrected QT interval [corrected by Fridericia formula]), mean QTc of 3 ECGs, QT interval measurement should start from QRS complex to the end of T wave);
- any clinically significant resting ECG abnormalities in rhythm, conduction or morphology, such as complete left bundle branch block, grade 2 and 3 heart block, PR interval > 250 ms, etc.;
- any factor that increases the risk of QTc prolongation or arrhythmia, such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome, etc. or unexplained sudden death in a first-degree relative under 40 years of age, or any concomitant medication known to prolong the QT interval;

Intervention / Treatment |
---|---|
Experimental: cohort-experimental
Patients will receive treatment observation every 21 days for up to 8 cycles.
Actual follow-up will be decided according to the patient 's condition and benefit, and each test requirement and data collection will be completed at specified time during the follow-up cycle.
|
Based on the development principle of NCV, a community-type tumor neoantigen mRNA vaccine, JCXH-212 injection, has been developed that can be applied to patients with advanced malignant solid tumors.
NCVs activate tumor-specific CD4+ T cells and CD8+ T cells through active immunity, and these T cells can inhibit and kill tumor cells in cancer patients, thus prolonging the survival of cancer patients.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
dose-limiting toxicity (DLT)
Time Frame: Up to 21 days after first dose every subject
|
Tolerability and safety analysis: determine the maximum tolerated dose (MTD) and determine the escalation of the relevant dose.
Incidence of DLTs was summarized overall and by dose level based on the DLT Analysis Set (DLTS).
|
Up to 21 days after first dose every subject
|
analysis of primary efficacy indicators
Time Frame: At the end of the time 3-6 months after last subject last dose
|
Efficacy analysis: In the study, correlation analysis will be performed between the main efficacy indicators and dose regimen in each dose group.
|
At the end of the time 3-6 months after last subject last dose
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
exploratory analysis of changes in peripheral blood neoantigen-specific T cell responses before and after administration
Time Frame: The day of administration of the last subject
|
Exploratory analysis: focus on describing changes in peripheral blood neoantigen-specific T cell responses before and after administration and the possible association or predictive role of such changes with treatment outcome
|
The day of administration of the last subject
