Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Patients must have measurable disease, per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) for the evaluation of measurable disease

Patients must have received at least one prior treatment for metastatic disease and progressed on treatment or been intolerant to treatment

Must not have

Patients with active brain metastases or leptomeningeal metastases are excluded from this clinical trial

Patients with a history of myocarditis are excluded due to the potential of myocarditis with anti-PD-L1 antibodies or other immunotherapies

Timeline

Screening 3 weeks

Treatment Varies

Follow Up up to 1 year after completion of study medication

Awards & highlights

No Placebo-Only Group

Summary

This trial tests a combo of drugs & manufactured cells to fight metastatic GD2+ HER2- breast cancer.

Who is the study for?

This trial is for adults with metastatic, GD2 expressing, HER2 negative breast cancer who've had at least one prior treatment. They must understand the study and consent to it, have good organ function and performance status, resolved any previous therapy side effects to a mild level, and agree to use effective contraception. Excluded are those with certain allergies, recent other cancers or treatments, brain metastases, severe heart conditions or infections.

What is being tested?

The trial tests gemcitabine (a chemotherapy drug) combined with lab-grown NK cells that boost immune response against cancer cells. It also examines the addition of naxitamab—a monoclonal antibody targeting specific proteins on tumor cells—to this combination in patients whose tumors express a particular protein called GD2.

What are the potential side effects?

Potential side effects include reactions related to the immune system's enhancement such as fever and fatigue; typical chemotherapy-related issues like nausea; blood cell count changes leading to increased infection risk; possible allergic reactions; and infusion-related responses from monoclonal antibodies.

4Treatment groups

Experimental Treatment

Group I: Arm IV (Gemcitabine, naxitamab, TGFBi x2)Experimental Treatment6 Interventions

Patients receive gemcitabine IV over 30 minutes on days 1, 8, and 15 of each cycle followed by naxitamab IV over 30-60 minutes on days 1, 4, and 8 of each cycle. Cycles repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients receive TGFBi NK cells IV over 10-30 minutes on day 16 and 18 of cycle 1. Patients undergo CT scan and blood sample collection and may undergo MRI throughout the study.

Group II: Arm III (Gemcitabine naxitamab, TGFBi)Experimental Treatment6 Interventions

Patients receive gemcitabine IV over 30 minutes on days 1, 8, and 15 of each cycle followed by naxitamab IV over 30-60 minutes on days 1, 4, and 8 of each cycle. Cycles repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients receive TGFBi NK cells IV over 10-30 minutes on day 16 of cycle 1. Patients undergo CT scan and blood sample collection and may undergo MRI throughout the study.

Group III: Arm II (Gemcitabine, TGFBi x2)Experimental Treatment5 Interventions

Patients receive gemcitabine IV over 30 minutes on days 1, 8, and 15 of each cycle. Cycles repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients receive TGFBi NK cells IV over 10-30 minutes on day 16 and 18 of cycle 1. Patients undergo CT scan and blood sample collection and may undergo MRI throughout the study.

Group IV: Arm I (Gemcitabine, TGFBi)Experimental Treatment5 Interventions

Patients receive gemcitabine intravenously (IV) over 30 minutes on days 1, 8, and 15 of each cycle. Cycles repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients receive TGFBi NK cells IV over 10-30 minutes on day 16 of cycle 1. Patients undergo CT scan and blood sample collection and may undergo MRI throughout the study.
