Clinical Trial 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

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dose limiting toxicity	Dose limiting toxicity, evaluated in the Phase Ia, which will be used to determine the MTD and to determine dose escalation.	Within 28 days after the first dose
Primary	Incidence of adverse events (Safety and Tolerability)	Safety and tolerability as determined by the incidence of adverse events (AEs), including severe AEs and serious AEs (SAEs).	From consent to 28 days after the last dose of study drug
Secondary	Objective response rate (ORR)	Objective response rate is defined as the proportion of patients that achieve a complete response (CR) or partial response (PR) during the study participation.	Up to 12 months
Secondary	Duration of response (DoR)	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.	Up to 12 months following first reported response
Secondary	Disease control rate (DCR)	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.	Up to 12 months
Secondary	Time to response (TTR)	Time to response is defined as the time from Day 1 until the first documentation of objective response (CR or PR).	Up to 12 months from the start of study therapy
Secondary	Progression-free survival (PFS)	Progression-free survival is defined as the time from Day 1 to disease progression or death from any cause, whichever occurs earlier.	Up to 12 months
Secondary	Overall survival (OS)	Overall survival is defined as the time from Day 1 until death due to any cause.	Up to 24 months
