Anti-GD2-800CW imaging to highlight neuroblastoma during surgery

A Phase Ib/II First-in-human Imaging Study of Anti-GD2-800CW in Patients With Neuroblastoma

Phase1; Phase2 Interventional Princess Maxima Center for Pediatric Oncology · NCT07399821

This trial will test whether a fluorescent antibody called anti-GD2-800CW can safely help surgeons see and remove neuroblastoma in children ages 1 to 18.

What this trial studies

This is an open-label phase Ib/II dose-escalation and expansion trial testing anti-GD2-800CW, a near-infrared fluorescent antibody, for intraoperative visualization of neuroblastoma. Children scheduled for standard-of-care tumor resection will receive a single dose of the agent before surgery and surgeons will use NIR fluorescence imaging to locate tumor tissue during the operation. The study will define a recommended imaging dose based on safety, tolerability, and intraoperative tumor detection performance. It is non-randomized and conducted at the Princess Maxima Centrum for Pediatric Oncology.

Who should consider this trial

Good fit: Children aged 1 to 18 with histologically confirmed neuroblastoma who are scheduled for surgical resection and have not previously received dinutuximab-beta are ideal candidates.

Not a fit: Patients who have received prior dinutuximab-beta, are pregnant or breastfeeding, or are not undergoing surgery are unlikely to benefit from this imaging approach.

Why it matters

Potential benefit: If successful, the agent could help surgeons see tumor tissue more clearly during operations, reducing complications and leftover tumor.

How similar studies have performed: Fluorescence-guided surgery has improved intraoperative tumor visualization in several adult cancers and early work with GD2-targeting agents supports feasibility, but using anti-GD2-800CW in pediatric neuroblastoma is early-phase and not yet proven.

Eligibility criteria
