A Phase 1 Open-Label Study to Evaluate the Safety, Tolerability and Efficacy of JCXH-211 Intratumoral Injection in Patients With Malignant Solid Tumors

: A Phase 1 Open-Label Study to Evaluate the Safety, Tolerability and Efficacy of JCXH-211 Intratumoral Injection in Patients with Malignant Solid Tumors

Study Overview

Status

Completed

Intervention / Treatment

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.

Description

Inclusion Criteria:

  • Male or female patients 18-75
  • Patients with malignant solid tumors that have been diagnosed by pathology and/or cytology

Exclusion Criteria:

  • Patients with tumors that impinge on major airways, blood vessels, or nerve bundles
  • Patients with a history of autoimmune disease that has the possibility of recurrence or active autoimmune disease that requires immunosuppressive medications
  • Patients who had a major surgical procedure within 4 weeks prior to the first dose of study treatment
  • Current or prior use of immunosuppressive medication within 2 weeks prior to the first dose of study treatment
  • Patient with history of solid organ or allogenic bone marrow transplantation

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of adverse events (Safety and Tolerability)
Time Frame: 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).
From consent to 28 days after the last dose of study drug
Dose limiting toxicity
Time Frame: Within 28 days or 14days 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.
Within 28 days or 14days after the first dose

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Duration of response (DoR)
Time Frame: 6 months after the last patient is enrolled.
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.
6 months after the last patient is enrolled.
Disease control rate (DCR)
Time Frame: 6 months after the last patient is enrolled.
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.
6 months after the last patient is enrolled.
Progression-free survival (PFS)
Time Frame: 6 months after the last patient is enrolled.
Progression-free survival is defined as the time from Day 1 to disease progression or death from any cause, whichever occurs earlier.
6 months after the last patient is enrolled.
Overall survival (OS)
Time Frame: 6 months after the last patient is enrolled.
Overall survival is defined as the time from Day 1 until death due to any cause.
6 months after the last patient is enrolled.
Objective response rate (ORR)
Time Frame: 6 months after the last patient is enrolled.
Objective response rate is defined as the proportion of patients that achieve a complete response (CR) or partial response (PR) during the study participation.
6 months after the last patient is enrolled.
Clinical benefit rate (CBR)
Time Frame: 6 months after the last patient is enrolled.
Clinical benefit rate is defined as the proportion of patients with the best response of CR, PR, or SD (duration ≥ 24 weeks) throughout the study from Day 1 of treatment with the study drug to disease progression.
6 months after the last patient is enrolled.
