Study to Evaluate JCXH-211 as Monotherapy in Patients With Malignant Solid Tumors

Immorna Biotherapeutics, Inc.1 enrolled

Overview

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

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 3 stages, Single administration stage, Multiple administration stage and Visceral 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.

Outcomes

Primary Outcomes

Dose limiting toxicity

Dose limiting toxicity, evaluated in the single administration stage of Phase 1a, which will be used to determine the MTD and to determine dose escalation

Time frame: Day 1 to Day 29

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)

Time frame: From consent to 30 days after the last dose of study drug

Secondary Outcomes

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.

Time frame: Up to 12 months

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.

Time frame: Up to 12 months following first reported response

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).

Time frame: Up to 12 months from the start of study therapy

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 ≥ 12 weeks observed from Day 1 to disease progression.

Time frame: Up to 12 months

Progression-free survival (PFS)
