NL-201 Stimulates CD8 Effector T and NK Cells More Selectively Than IL-2 NL-201 is ~330-fold and ~90-fold more selective for CD8+ T and NK cells (vs. Tregs) than IL-2, respectively STAT5 phosphorylation in CD8+ T cells, NK cells, and Tregs was measured by flow cytometry using PBMCs from 10 healthy human donors. Proliferation was evaluated using Ki67. Walkey et. al, AACR Virtual Annual Meeting II, Abstract #4518, June 2020

NL-201 is Well Tolerated and Promotes Durable Anti-tumor Activity NL-201 is well-tolerated at therapeutic doses NL-201 treatment exhibits single-agent activity NL-201 promotes durable anti-tumor immunity Study in a checkpoint inhibitor-resistant CT26 colon cancer murine model. Walkey et. al, AACR Virtual Annual Meeting II, Abstract #4518, June 2020
NL-201 Demonstrates Robust Single-Agent Activity in Multiple Tumor Models NL-201 was administered QWx2 when tumors reached ~100mm3. Tumor growth inhibition (TGI) is reported in each graph vs. control. NL-201 treatment inhibited tumor growth in all models: NL-201 significantly inhibited tumor growth in models that are typically refractory to anti-PD-1 checkpoint inhibitors.
