Material Balance of [14C]Zorifertinib in Healthy Adult Male Participants in China

This is a single-center, single-dose, open-label, Phase I study to evaluate the mass balance, biotransformation, pharmacokinetic characteristics, excretion pathways, and safety of a single oral 200 mg/5 µCi dose of \[14C\]Zorifertinib in healthy Chinese adult male participants. The study includes a screening period (Day -14 to Day -1) and a dosing and observation period (Day 1 to Day 14). Blood, urine, and feces samples will be collected to measure radioactivity, drug concentrations, and metabolites. Safety will be assessed by adverse events, vital signs, laboratory tests, 12-lead ECG, and ophthalmic examinations. The target total radioactivity recovery is ≥90% of the administered dose.

A Phase II Observational Clinical Study on the Relationship Between Cerebrospinal Fluid Drug Concentration and Efficacy of Trastuzumab Deruxtecan in Central Nervous System Metastatic Breast Cancer

Approximately 5-15% breast cancer patients develop brain metastases. Current local treatments (surgery/radiotherapy) are associated with significant complications, and systemic treatments have limited efficacy. Although new-generation ADC drugs, such as trastuzumab deruxtecan, have demonstrated breakthrough efficacy in patients with brain metastases, the mechanisms of action are not fully elucidated, moreover the current treatment regimens still have limitations for patients with HER2-low expressing, safer and more effective systemic treatment options are urgently needed to improve patient survival. BCBM-006 is an open-label, prospective, single-arm, single-center Phase II clinical study to evaluate the relationship between cerebrospinal fluid drug concentration and efficacy of trastuzumab deruxtecan in central nervous system metastatic breast cancer, and explore the incidence of leptomeningeal metastases diagnosed via lumbar puncture in patients with brain parenchymal metastases, facilitate early intervention to improve prognosis.

A Prospective Cohort Study of Zorifertinib as a First-line Treatment in Patients With Epidermal Growth Factor Receptor-mutant Advanced Non-small Cell Lung Cancer With Central Nervous System (CNS) Metastases

This study is a patient-centered, two-group, three-cohort, multi-center, prospective study to further evaluate the survival benefits and safety of zorifertinib as a first-line treatment in EGFRm+ advanced NSCLC patients with CNS metastases, and to compare the clinical value of zorifertinib with other epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs).
