Intervention type:
Biological
Intervention name:
JCXH-212 Injection
Description:
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
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.
Arm group label:
cohort-experimental
Summary:
To evaluate the safety and tolerability of JCXH-212 monotherapy and combined with
Toripalimab in patients with malignant solid tumors; to determine the maximum tolerated
dose (MTD), and to evaluate the dose-limiting toxicity (DLT) of JCXH-212 monotherapy and
combined with Toripalimab.
Detailed description:
This study uses 3+3 clinical design. About 12-24 patients with solid tumor malignancies
are expected to be enrolled in this study.
For JCXH-212 monotherapy, 2 dose groups are set for dose escalation (100μg, 200μg). Doses
were administered every 21 days, with a DLT observation period of 21 days after the first
dose. After completion of DLT assessment, the investigator decided whether to continue
the treatment after the end of DLT assessment based on the subject 's tolerance and the
safety profile of the dose group. Subjects may continue to receive dosing if the
investigator determines that the subject is benefiting from continued treatment. No more
than 8 total doses of JCXH-212 will be administered.
For JCXH-212 combined with Toripalimab, 2 dose groups are set for dose escalation (100μg,
200μg of JCXH-212). JCXH-212 will be administered every 6 weeks, with a DLT observation
period of 21 days after the first dose. Toripalimab (240mg per dose) will be
administrated every 3 weeks. After completion of DLT assessment, the investigator decided
whether to continue the treatment after the end of DLT assessment based on the subject 's
tolerance and the safety profile of the dose group. Subjects may continue to receive
JCXH-212 if the investigator determines that the subject is benefiting from continued
treatment. No more than 8 total doses of JCXH-212 will be administered.
