Study to Evaluate JCXH-211 as Monotherapy in Patients With Malignant Solid Tumors
- Conditions
- Malignant Solid TumorCutaneous Tumor
- Interventions
- Drug: JCXH-211 Injection
- Registration Number
- NCT05727839
- Lead Sponsor
- Immorna Biotherapeutics, Inc.
- Brief Summary
: A Phase 1 Open-Label Study to Evaluate the Safety, Tolerability and Efficacy of JCXH-211 Intratumoral Injection in Patients with Malignant Solid Tumors
- Detailed Description
The main purpose of this study is to find out how safe and tolerable the study drug, JCXH-211, is and also how well it works in people with malignant solid tumors. The study drug JCXH-211, is an immunotherapy drug. This means that it aims to work by boosting immune system's response to tumors, to help fight against the growth of the cancer cells. The study has 2 main phases: Phase
1a and Phase 1b. Phase 1a has 2 stages, skin/subcutaneous lesions stage, deep (visceral) lesions stage. Phase 1b will not start until all the data collected in Phase 1a has been completed and reviewed to check that it is safe and well tolerated.

Group Intervention Description Phase Ia:Dose escalation JCXH-211 Injection JCXH-211 will be delivered by intratumoral injection in 2 stages: （Part1）Intratumoral injection stage of skin/subcutaneous lesions. According to Part 1 study results,1-2 dose groups were selected for deep lesion injection study, dose escalation will follow the "3 + 3" principle. Phase Ib: Dose Extension JCXH-211 Injection JCXH-211 will be delivered by intratumoral injection. The dose to be used will be determined after review of the data from Phase Ia.
- Primary Outcome Measures
Name Time Method Incidence of adverse events （Safety and Tolerability） From consent to 28 days after the last dose of study drug Safety and tolerability as determined by the incidence of adverse events （AEs）, including severe AEs and serious AEs （SAEs）.
Dose limiting toxicity Within 28 days after the first dose Dose limiting toxicity, evaluated in the Phase Ia, which will be used to determine the MTD and to determine dose escalation.
- Secondary Outcome Measures
Name Time Method Time to response （TTR） Up to 12 months from the start of study therapy Time to response is defined as the time from Day 1 until the first documentation of objective response （CR or PR）.
Disease control rate （DCR） Up to 12 months Disease control rate is defined as the proportion of patients with CR or PR or stable disease （SD） with the DoR ≥ 12weeks observed from Day 1 to disease progression.
Progression-free survival （PFS） Up to 12 months Progression-free survival is defined as the time from Day 1 to disease progression or death from any cause, whichever occurs earlier.
Overall survival （OS） Up to 24 months Overall survival is defined as the time from Day 1 until death due to any cause.
Objective response rate （ORR） Up to 12 months Objective response rate is defined as the proportion of patients that achieve a complete response （CR） or partial response （PR） during the study participation.
Duration of response （DoR） Up to 12 months following first reported response Duration of response is defined as the time from the first assessment of tumor as CR or PR to the first assessment as progressive disease or death from any cause.
