Evaluating FZ-AD005 for patients with advanced solid tumors

A PhaseⅠStudy to Evaluate the Safety, Tolerability, Pharmacokinetics and Efficacy of FZ-AD005 in Patients With Advanced Solid Tumors

Phase 1 Interventional Shanghai Fudan-Zhangjiang Bio-Pharmaceutical Co., Ltd. · NCT06424665

This study is testing a new treatment called FZ-AD005 to see if it can help people with advanced solid tumors like small cell lung cancer and large cell neuroendocrine carcinoma.

What this trial studies

This is a first-in-human, open-label Phase I study designed to assess the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of FZ-AD005 in patients diagnosed with advanced solid tumors, particularly small cell lung cancer (SCLC) and large cell neuroendocrine carcinoma (LCNEC). Participants will be required to provide tumor tissue samples for testing and must have measurable lesions as defined by RECIST criteria. The study aims to determine the potential effectiveness of FZ-AD005 in treating these challenging cancer types.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 75 with advanced solid tumors, specifically SCLC or LCNEC, who can provide informed consent and have measurable lesions.

Not a fit: Patients with active CNS metastasis or those who have previously received treatment with anti-DLL3 antibodies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced solid tumors, potentially improving their outcomes.

How similar studies have performed: While this approach is novel in the context of FZ-AD005, similar studies targeting advanced solid tumors have shown promise in the past.
