TAA06 injection for treating B7-H3-positive neuroblastoma

An Open-label, Dose-escalation, and Dose-expansion Phase I Trial of TAA06 Injection in Patients With Relapsed/Refractory Neuroblastoma

Phase 1 Interventional PersonGen BioTherapeutics (Suzhou) Co., Ltd. · NCT05562024

This study is testing a new T cell injection called TAA06 to see if it can safely help patients with hard-to-treat neuroblastoma that has come back.

What this trial studies

This Phase I clinical trial evaluates the safety and tolerability of TAA06, a T cell injection targeting B7-H3, in patients with relapsed or refractory neuroblastoma. The trial employs a dose-escalation design, enrolling 12-18 subjects across three dose groups to assess dose-limited toxicity and determine the recommended phase 2 dose (RP2D). Following safety evaluations, the study will expand to include more patients at the RP2D to gather additional efficacy and pharmacokinetic data.

Who should consider this trial

Good fit: Ideal candidates are children aged 1 year and older with B7-H3-positive relapsed or refractory neuroblastoma.

Not a fit: Patients who have not undergone at least one line of standard treatment or those with a Karnofsky/Lansky score below 60 may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat neuroblastoma.

How similar studies have performed: While this approach is novel in targeting B7-H3, similar immunotherapy strategies have shown promise in other cancers.

* Participated in other clinical studies within 1 month before screening
* Subjects screened for evidence of central nervous system involvement
* For patients with liver metastases, the distribution of liver metastases exceeds 1/2 of the liver
