About IRX-2

IRX-2 is a primary cell-derived biologic. Data collected to date suggest that IRX-2 reduces the immune suppression that is often seen in the cancer tumor microenvironment. This immunomodulatory activity appears to occur through the restoration of immune function and activation of a coordinated immune response against the tumor. IRX-2 is a proprietary therapeutic containing numerous active cytokine components, which restores and activates multiple immune cell types, including T cells, dendritic cells, and natural killer cells, that are able to recognize and destroy tumors. Currently, IRX-2 is being studied in an on-going Phase 2b clinical trial in patients with newly diagnosed Stage II, III, and IVA squamous cell carcinoma of the head and neck (SCCHN) (INSPIRE) ( NCT02609386) and in pre-operative early stage breast cancer (ESBC) ( NCT02950259).

IRX-2 Phase 2a Results

Data collected in a Phase 2a trial of patients with squamous cell carcinoma of the head and neck (SCCHN) demonstrated that neoadjuvant IRX-2 stimulated lymphocyte infiltration (LI) into the tumors, and greater LI was associated with longer survival. The overall 5-year survival rate was 65{991a4518005c0acae110dc2957c3093c53aab3e18df24b42d60853d4cdca3513} (17/26), and in patients with a large change in LI after treatment, there was a greater than 80{991a4518005c0acae110dc2957c3093c53aab3e18df24b42d60853d4cdca3513} probability of survival at 5 years (LIavg vs. survival, p<0.05).1 Of the 27 patients evaluable for safety, 85.2{991a4518005c0acae110dc2957c3093c53aab3e18df24b42d60853d4cdca3513} experienced at least one treatment-emergent adverse event (TEAE), the most common (>10{991a4518005c0acae110dc2957c3093c53aab3e18df24b42d60853d4cdca3513}) study drug-related TEAEs included nausea, injection site pain, headache, and dizziness. There were no drug-related deaths reported.2
