What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 54 participants in total. It began in 2020-09-23 with a primary completion date of 2027-08-15.

Brief Summary

This phase I trial investigates the side effects and best dose of using a modified measles virus, MV-s-NAP, in treating patients with invasive breast cancer that has spread to other places in the body (metastatic). Both the unmodified vaccination measles virus (MV-Edm) and this modified virus (MV-s-NAP) have been shown to multiply in and destroy breast cancer cells in the test tube and in research mice. MV-s-NAP has been altered by having an extra gene (piece of deoxyribonucleic acid \[DNA\]) so that virus can make a protein called helicobacter pylori neutrophil activating protein (NAP) which is normally expressed in inflammatory reactions. Monitoring blood, urine, tissue, and throat swab samples, and using imaging tests may help to determine whether MV-s-NAP has any impact on the amount of disease present in metastatic breast cancer patients.

Eligibility Criteria

research purposes * Life expectancy \>= 12 weeks * Concomitant administration of a bone modifying agent (e.g., zoledronic acid or denosumab) is permitted for the prevention or management of skeletal related events in patients with bone metastases and documentation of tolerability with prior exposures Exclusion Criteria: * Known standard therapy for the patient's disease that is potentially curative or definitely capable of extending life expectancy * Clinical or radiographic suspicion of impending visceral crisis due to invasion or compression by tumor * Active infection =\< 5 days prior to registration * History of other malignancy =\< 5 years except for non-melanoma skin cancer or carcinoma in situ of the cervix * Any of the following prior therapies: * Chemotherapy =\< 3 weeks prior to registration * Immunotherapy =\< 4 weeks prior to registration * HER2 directed therapy =\< 3 weeks prior to registration * Targeted therapy =\< 2 weeks prior to registration (e.g., CDK4/6 inhibitors, everolimus) * Investigational agent =\< 4 weeks prior to registration * Any viral or gene therapy prior to registration * Failure to fully recover from acute, reversible effects of prior systemic therapy regardless of interval since last treatment * New York Heart Association classification III or IV, known symptomatic coronary artery disease, or symptoms of coronary artery disease on systems review, or known cardiac arrhythmias (atrial fibrillation or supraventricular tachycardia \[SVT\]) * Untreated or progressive central nervous system (CNS) metastases * NOTE:
