Combining intra-arterial cisplatin and rh-endostatin with chemotherapy for osteosarcoma

Efficacy and Safety of Intra-arterial Cisplatin Plus Anti-angiogenesis Inhibitor Rh-endostatin (Endostar) Combined With Systematic Chemotherapy in Osteosarcoma

Phase1; Phase2 Interventional Shanghai 6th People's Hospital · NCT06562673

This study is testing a new way to treat osteosarcoma by combining a targeted delivery of two drugs with standard chemotherapy to see if it helps patients feel better and fight the cancer more effectively.

What this trial studies

This clinical trial aims to evaluate the safety and efficacy of administering intra-arterial cisplatin alongside the anti-angiogenesis inhibitor rh-endostatin, combined with standard chemotherapy for patients diagnosed with osteosarcoma. The study will involve newly diagnosed patients aged 18-40, who will receive high-dose methotrexate and adriamycin intravenously, while rh-endostatin and cisplatin will be delivered directly to the tumor via a catheter. The goal is to determine if this approach increases tumor necrosis rates compared to traditional treatments, potentially improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients aged 18-40 with a confirmed diagnosis of osteosarcoma who are willing to undergo neoadjuvant chemotherapy.

Not a fit: Patients with severe liver or kidney dysfunction, recent acute injuries, or other malignancies may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could enhance tumor response rates and improve survival outcomes for osteosarcoma patients.

How similar studies have performed: Previous studies have shown promising results with similar intra-arterial chemotherapy approaches, indicating potential for success in this novel combination.
