About this study

Official title: 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

Patients with Small Cell Lung Cancer, High Risk Neuroblastoma, Sarcoma and Malignant Melanoma will be treated with GD2-SADA:177Lu-DOTA complex(The IMP is a two-step radioimmunotherapy, delivered as two separate products GD2-SADA and 177Lu-DOTA) to assess safety and tolerability

Read the detailed description

A phase 1 dose-escalation single-arm, open-label, non-randomized, multi-center trial of the safety and tolerability of GD2-SADA:177Lu-DOTA complex in GD2 expressing solid tumors.

The trial is planned as a Phase 1 trial with three parts, A, B and C. Escalation in this trial will be based on a classical 3+3 trial design.

Part A is a GD2-SADA dose escalation phase, in which patients will receive one treatment cycle.

Part B is a 177Lu-DOTA dose escalation phase, in which patients will receive up to 2 treatment cycles .

Part C is a repeated dosing phase where the doses determined in Part A and B will be administered. Patients will receive repeated treatment cycles with a maximum of 5 cycles.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GD2-SADA (0.3 mg/kg) and 177Lu-DOTA (30 mCi), GD2-SADA (3 mg/kg) 177Lu-DOTA (30 mCi) and GD2-SADA (0.3 mg/kg) 177Lu-DOTA (200 mCi) in people with SCLC and Malignant Melanoma, run by Y-mAbs Therapeutics at 8 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 18 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Jun 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Dose Limiting Toxicity (time frame: Within 6 weeks after first IMP administration). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jun 2026.
