SEATTLE, Nov. 12, 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 new preclinical data on NL-201, an alpha-independent, de novo-designed IL-2 and IL-15 dual agonist, at the Society for Immunotherapy of Cancer’s 36th Annual Meeting (SITC 2021).
The presentation highlights preclinical data on NL-201 alone and in several combination regimens. 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 IL-2 receptor alpha subunit (CD25).
“The SITC presentations highlight the broad potential of NL-201, which we believe to be the first fully de novo designed protein to enter clinical trials, to activate the immune system to fight cancer,” said Jonathan Drachman, M.D., Chief Executive Officer of Neoleukin. “New data demonstrate that NL-201 can activate the tumor microenvironment and increase T-cell receptor diversity. We also found that local, intratumoral administration can control both the injected and distant tumors with improved tolerability compared to systemic administration in pre-clinical models. We are pleased to share this research as we continue to advance the NL-201 phase 1 clinical trial.”
Further details from the presentations are as follows:

About NL-201
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.
About Neoleukin Therapeutics, Inc.
Neoleukin is a biopharmaceutical company creating next generation immunotherapies for cancer, inflammation and autoimmunity using de novo protein design technology. Neoleukin uses sophisticated computational methods to design proteins that demonstrate specific pharmaceutical properties that provide potentially superior therapeutic benefit over native proteins. Neoleukin’s lead product candidate, NL-201, is a combined IL-2 and IL-15 agonist designed to improve tolerability and activity by eliminating the alpha receptor binding interface.
