A New Way Forward
for Autoimmune Disease
Our Mission
Why We’re Here
We’re a biotechnology company with a big ambition: to transform the standard of care for autoimmune disease. By unlocking the innate power of natural killer (NK) cells — the immune system’s first responders — we’re working to eliminate malfunctioning B cells at the heart of some of medicine’s most devastating autoimmune conditions with the aim of alleviating suffering and delivering better health.
Patients First
Our Clinical Trial Promise
Instead of asking people with serious diseases to reconstruct their lives around our studies, drug developers should be striving to design our research around their lives. Read about what we’re doing to make clinical trial opportunities more accessible and equitable.

Boosted Killer Cells Show Promise For Autoimmune Disease
“Supercharged ‘natural killer’ cells could become a potent way to reset a disordered immune system,” according to one of the world's most prestigious scientific journals.

Our Autoimmune Targets
We are dedicated to realizing the potential of natural killer (NK) cells for the treatment of autoimmune diseases. Our proprietary technology is designed to harness the inherent disease-fighting capabilities of these immune cells to act against cells that are dysfunctional, diseased or otherwise abnormal.

#LupusAwarenessMonth is a reminder of how much work remains in getting to a diagnosis. Marisa Zeppieri waited 15 years from the onset of symptoms that compounded as she grew older for reasons that eluded dozens of doctors. As a member of Gen X coming of age before the internet normalized health information sharing, she was failed by the medical establishment from elementary to graduate school.
Marisa recalls the bittersweet taste of going from limbo to #lupus diagnosis at age 23 when her lifetime’s worth of medical symptoms all flared at once during her prolonged hospitalization from a 2001 vehicular trauma. That experience led Marisa to become one of the first visible lupus patient advocates of the social media era, starting in 2004. Today, as a journalist, author, advocate, and speaker, she reaches 8 million people a month on her social channels and Lupus Chick website, a nonprofit she created to demystify the disease and build a support system for patients facing isolation and stigma.
Earlier this year, Marisa shared her story with our employees in a riveting and emotional fireside chat with her husband Mickey at Nkarta headquarters. Her poise and resilience were deeply impactful as she tearfully thanked us for tackling autoimmunity at its cellular roots and offering hope for a future less defined by flares, fever, fatigue, and joint damage.
