Scientific title

A Phase I/Ib Open-label, Multi-center Dose Escalation Study of JBH492 in Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia (CLL) and Non-Hodgkin's Lymphoma (NHL)


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

For patients with CLL:

• Confirmed diagnosis of chronic lymphocytic leukemia (CLL)

For patients with NHL:

Histologically confirmed diagnosis of B- or T-cell non-Hodgkins lymphoma (NHL).Must have a site of disease amenable to biopsy, and be suitable and willing to undergo study required biopsies at screening and during therapy.

, applicable to both CLL and NHL:

History of anaphylactic or other severe hypersensitivity/infusion reactions to ADCs, monoclonal antibodies (mAbs) and/or their excipients such that the patient in unable to tolerate immunoglobulin/monoclonal antibody administrationAny prior history of treatment with maytansine (DM1 or DM4)-based ADC Known intolerance to a maytansinoid Patients with any active or chronic corneal disorders Patients who have any other condition that precludes monitoring of the retina or fundus Patients with active CNS involvement are excluded, except if the CNS involvement has been effectively treated and provided that local treatment was > 4 weeks before enrollment. Patients that have been effectively treated for CNS disease and are stable under systemic therapy may be enrolled provided all other inclusion and exclusion criteria are met. Impaired cardiac function or clinically significant cardiac disease Known history of Human Immunodeficiency Virus (HIV) infection Active Hepatitis B Virus (HBV) or Hepatitis C Virus (HCV) infection

Other inclusion and exclusion criteria may apply.
