Clinical Trial Summary

This research study involves two investigational drugs, an Activator Ligand (INXN-1001) in combination with an Adenovirus Vector Engineered to Express hIL-12 (INXN-2001). IL-12 is a protein that may improve the body's natural response to disease by enhancing the ability of the immune system to kill tumor cells and may interfere with blood flow to the tumor.

The main purpose of this study is to evaluate the safety and tolerability of tumor injections of INXN-2001 given in combination with different doses of INXN-1001.


Clinical Trial Description

Single-arm, open label, Phase I/II dose escalation study of intratumoral injections INXN-2001 and oral INXN-1001 in subjects with unresectable Stage III or IV melanoma.

Four sequential dose escalation cohorts of INXN-1001 in combination with a fixed dose of INXN-2001 are planned. Subject enrollment and dose escalation will proceed according to a standard 3+3 design.

Approximately 15 additional subjects will be enrolled as an expansion cohort at a single dose level at or below the MTD.

- Safety and tolerability will be assessed by the incidence and severity of adverse events.

- The antitumor activity of study treatment will be assessed according to RECIST v1.1 guidelines. Additional assessment of anti-tumor activity will be explored based on total measurable tumor burden.

- Immunological and biological markers of response will include examinations of tumor biopsy samples, cytokine levels, peripheral blood mononuclear cells (PBMC) and antibody response to INXN-2001. ;
