Treatment for solid tumors expressing GD2 using a radioimmunotherapy complex

Phase 1 Trial With GD2-SADA:177Lu-DOTA Drug Complex in Patients With Recurrent or Refractory Metastatic Solid Tumors Known to Express GD2, Including Small Cell Lung Cancer, High Risk Neuroblastoma, Sarcoma and Malignant Melanoma

Phase 1 Interventional Y-mAbs Therapeutics · NCT05130255

This study is testing a new treatment using a special radioimmunotherapy for patients with solid tumors that have GD2, like certain lung cancers and melanomas, to see if it is safe and effective.

What this trial studies

This phase 1 trial evaluates the safety and tolerability of the GD2-SADA:177Lu-DOTA complex in patients with solid tumors known to express GD2, including Small Cell Lung Cancer, Malignant Melanoma, Sarcoma, and High Risk Neuroblastoma. The trial consists of three parts: a dose escalation for GD2-SADA, followed by a dose escalation for 177Lu-DOTA, and a repeated dosing phase based on the determined doses. Patients will receive up to five treatment cycles, allowing researchers to assess the therapeutic potential of this innovative approach.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older, and adolescents aged 16 and older with measurable GD2-expressing solid tumors and an expected survival of more than three months.

Not a fit: Patients who have received systemic chemotherapy, radiotherapy, immunotherapy, or major surgery within three weeks prior to the trial may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with GD2-expressing solid tumors.

How similar studies have performed: While this approach is novel, similar radioimmunotherapy strategies have shown promise in other studies, indicating potential for success.
