About Nkarta


Founded in 2015 at the birthplace of biotechnology, our development pipeline of engineered NK cell therapy candidates includes two co-lead clinical programs, NKX101 and NKX019. Clinical trials for 101 are in process; 019 will begin in H2 2021. Nkarta recently announced a collaboration with CRISPR Therapeutics, a world leader in gene-based medicines, for the development and commercialization of up to three new cell therapy candidates and access to clinically validated CRISPR/Cas9 genome engineering.


Complementing our broad research and development capabilities, Nkarta has also built an extensive cell therapy manufacturing operation.  We have a 2,700-square foot clinical good manufacturing practice, or cGMP, facility on-site at our primary corporate location in South San Francisco, California. We plan to start in-house manufacturing of NKX019 in 2021 and NKX101 in 2022. We are also currently designing a separate, larger cGMP facility, to supply our anticipated pivotal clinical trial and commercial needs.
