F16IL2 in combination with paclitaxel

Philogen S.p.A. · Phase 1 active Small molecule ✓ Verified Jun 2026 Quality 40/100

F16IL2 in combination with paclitaxel is a Immunocytokine Small molecule drug developed by Philogen S.p.A.. It is currently in Phase 1 development.

F16IL2 targets tumor vasculature via antibody fragment F16 and delivers IL-2 to stimulate immune response at the tumor site, combined with paclitaxel chemotherapy.

F16IL2 in combination with paclitaxel is being studied in clinical trials for various conditions, including Merkel Cell Carcinoma, Solid Tumor, Breast Cancer, Metastatic Melanoma, and Non-small Cell Lung Cancer (NSCLC). The study, identified as NCT02054884, is a Phase II trial conducted by Philogen S.p.A. to evaluate the efficacy of F16IL2 plus paclitaxel in patients with metastatic Merkel Cell Carcinoma.

Mechanism of action

F16IL2 is an immunocytokine consisting of the F16 antibody fragment that binds to the A1 domain of tenascin-C, a protein overexpressed in tumor vasculature and stroma, fused to interleukin-2. This targets IL-2-mediated immune activation to the tumor microenvironment. Paclitaxel provides cytotoxic chemotherapy activity.
