Details and patient eligibility

About

The purpose of the First-In-Human study was to assess the safety, tolerability, pharmacokinetics (PK), immunogenicity and preliminary efficacy of JBH492 as single agent.

Full description

This was a FIH, open-label, phase I/Ib, multi-center study, which consisted of a dose escalation part of JBH492 as a single agent, followed by an expansion part. The escalation part was conducted in patients with relapsed/refractory chronic lymphocytic leukemia (r/r CLL) and Non-Hodgkin's Lymphoma (r/r NHL). Once the maximum tolerated dose/recommended dose (MTD/RD) of single agent JBH492 was determined, the study continued with an expansion part with single agent JBH492 in defined patient populations.
