Associate Director, Process Development

Over the past decade we have seen important advances in the cellular immunotherapy therapy field in particular, with dramatic rates of clinical response in hematological malignancies, and rapid evolution of our understanding of factors that could extend this success to solid tumors. However, these transformative therapies are often accompanied by severe and potentially life-threatening toxicities, and patient access is limited by such factors as complex, time-consuming patient-specific manufacturing, variable product quality, and cost.

Our Mission

At Artiva, our mission is to deliver highly effective cell therapies that are also safe and immediately available and accessible to any patient who stands to benefit.
