Experiment 1 Reporting the Activity Date of This ADC [1]
Patients Enrolled
Eligible patients must have HER2+ non-breast solid tumors refractory to standard therapies (ECOG ≤2) with biopsy-accessible lesions. Key exclusions include prior TLR7/8 treatment, cardiac dysfunction, autoimmune/active lung diseases, HIV, checkpoint inhibitor toxicity history, or QT-prolonging drug use. Additional protocol criteria may apply.
Administration Dosage
As of July 01, 2020, 18 patients (10 males, 8 females; median age, 52.5 years [range, 42-74 years]) were enrolled in 5 dose cohorts (0.1-1.6 mg/kg).
Related Clinical Trial
NCT Number NCT03696771  Clinical Status PHASE1
Clinical Description
A Phase I, Multicenter, Open-label Dose Finding Study of NJH395, Administered Intravenously in Patients With Non-breast HER2+ Advanced Malignancies
Primary Endpoint
Dose-limiting toxicities (DLTs) incidence and severity will be assessed over 21 days, extending to 42 days in the second study phase. Adverse event data collection spans 2.5 years.
Other Endpoint
PK profiles for NJH395 and metabolites will be tracked for 126 days, including Cmax/AUC measurements. Anti-drug antibody assessment and efficacy endpoints (ORR, CBR, PFS, DOR per RECIST v1.1/iRECIST) will be evaluated over 2.5 years. Tumor infiltrating lymphocyte changes will be monitored via IHC at specified treatment cycles (21-day intervals).
