Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data stable disease (SD)
8%
Patients Enrolled
Inclusion criteria for CLL patients require a confirmed diagnosis, while NHL patients must have a histologically confirmed diagnosis and be willing to undergo biopsies. Exclusion criteria apply to both groups, covering hypersensitivity to ADCs or mAbs, prior DM1/DM4 ADC treatment, corneal disorders, CNS involvement (unless treated), cardiac impairment, HIV, and active HBV/HCV (with controlled cases under antivirals eligible). Additional criteria may apply.

Administration Dosage
Five dose levels of JBH492 monotherapy ranging from 0.4 to 3.6 mg/kg (intravenous administration every 3 weeks [q3W]) were tested with 3 - 7 pts enrolled per dose level.

NCT Number NCT04240704  Clinical Status PHASE1
Clinical Description 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)
Primary Endpoint
The study evaluates the incidence and severity of dose-limiting toxicities (DLTs), adverse events (AEs), and serious adverse events (SAEs) over 32 months, with DLTs defined as protocol-specified adverse events during the first treatment cycle. It also measures treatment interruptions, dose reductions, and dose intensity, where relative dose intensity is calculated for subjects with non-zero exposure.

Other Endpoint
Key efficacy outcomes include overall response rate (ORR), best overall response (BOR), duration of response (DOR), and progression-free survival (PFS) over 32 months. Pharmacokinetic (PK) parameters cover AUClast, AUCinf, AUCtau, Cmax, Cmin, Tmax, and T1/2 for four analytes, alongside anti-JBH492 antibody incidence.
