– Poster presentation highlights NL-201 activity in multiple myeloma stem cell transplant model –
– Abstract reports activity of NL-201 as monotherapy and anti-PD1 combination in non-Hodgkin lymphoma model –
SEATTLE, Dec. 11, 2021 (GLOBE NEWSWIRE) -- Neoleukin Therapeutics, Inc., “Neoleukin” (NASDAQ:NLTX), a biopharmaceutical company utilizing sophisticated computational methods to design de novo protein therapeutics, today announced the presentation of preclinical data on NL-201 in multiple myeloma at the 63rd American Society of Hematology (ASH) Annual Meeting and Exposition taking place virtually and in person December 11-14, 2021. Additionally, a published abstract in Blood reports on NL-201 antitumor activity in preclinical studies of non-Hodgkin lymphoma.
NL-201 is a de novo agonist of the IL-2 and IL-15 receptors, designed to expand cancer-fighting CD8 T cells and natural killer (NK) cells without a bias toward cells expressing the IL-2 receptor alpha subunit (CD25). NL-201 is currently in a Phase 1 clinical trial for patients with solid tumors.
The preclinical multiple myeloma data, to be presented in a poster session by Simone A. Minnie, PhD, Fred Hutchinson Cancer Research Center, demonstrate the ability of NL-201 to prevent relapse in murine myeloma models following autologous stem cell transplant. Experimental results indicate that anti-myeloma activity is mediated by expansion of cytotoxic memory CD8 T cells and a decrease in T-regulatory CD4 cells in the bone marrow. Furthermore, NL-201 treated mice had an increase in bone marrow T-cells expressing granzyme B and a decrease in the T-cell exhaustion phenotype.
“These data, generated by our collaborators at the Fred Hutchinson Cancer Research Center, demonstrate robust immune effects and anti-myeloma activity in a challenging setting,” said Priti Patel M.D., Chief Medical Officer of Neoleukin. “Together with our published results on the preclinical activity of NL-201 against B-cell lymphoma, we believe that a clinical trial of NL-201 in patients with hematologic malignancies is warranted. We expect to initiate a Phase 1 trial in 2022 to evaluate NL-201 in patients with these indications.”

NL-201 is a de novo agonist of the IL-2 and IL-15 receptors, designed to expand cancer-fighting CD8 T cells and natural killer (NK) cells without any bias toward cells expressing the alpha receptor subunit (CD25). Previously presented preclinical data has demonstrated the ability of NL-201 to stimulate and expand CD8+ and NK cells at low doses with minimal impact on immunosuppressive regulatory T cells. Furthermore, NL-201 has demonstrated both monotherapy and combination activity across a wide range of preclinical syngeneic tumor models.
