The study will consist of 2 parts: dose-escalation (Part 1) and dose-expansion (Part 2). The dose-escalation part (Part 1) of the study is to evaluate the safety and tolerability of increasing dose levels of IKS03 to establish a recommended dose for expansion (RDE); and the dose-expansion part (Part 2) of the study is to further evaluate the safety, pharmacokinetics/pharmacodynamics, and efficacy of IKS03 at the RDE.
This first-in-human study will evaluate the recommended dose for further clinical development, safety, tolerability, antineoplastic activity, immunogenicity, pharmacokinetics and pharmacodynamics of IKS03, a CD19 targeting antibody-drug conjugate, in patients with advanced B cell non-Hodgkin lymphoma (NHL).
