Immunotherapy drug candidate that underwent a Phase 1 human clinical trial in cancer patients
NL-201 was an immunotherapy drug candidate that underwent a Phase 1 human clinical trial in cancer patients.[1] It is a de novo protein that was first computationally designed at the Institute of Protein Design (IPD), University of Washington.[2] In November 2022, Neoleukin Therapeutics announced it would discontinue the development of NL-201.[3]
History
The predecessor of NL-201, neoleukin-2/15, was first described and published on Nature magazine in January 2019.[2] The citizen science distributed computing project Rosetta@home, based at the University of Washington, contributed with "forward folding" experiments that helped validate protein designs of neoleukin-2/15, from which NL-201 was further developed by Neoleukin Therapeutics, a biopharmaceutical company that originated at the IPD.[4][5]
The Phase 1 human clinical trial began on May 5, 2021.[6]
In January 2022, Neoleukin Therapeutics announced a collaboration with Merck for a combination clinical trial of Merck's Pembrolizumab and Neoleukin's NL-201.[7]
In November 2022, Neoleukin Therapeutics announced it would discontinue the development of NL-201.[3]
