Summary

This trial is investigating the side effects and best dose of a modified measles virus, MV-s-NAP, in treating patients with metastatic breast cancer.

Who is the study for?

Adults with invasive breast cancer that has spread (metastatic) and no curative standard therapy available. Must have good organ function, acceptable blood counts, ECOG status 0-2, and a life expectancy of at least 12 weeks. Cannot be pregnant or have had certain treatments recently.

What is being tested?

The trial is testing MV-s-NAP, a modified measles virus designed to target and destroy breast cancer cells by producing an inflammatory protein called NAP. The study will determine the best dose and monitor its effects on metastatic breast cancer through various tests.

What are the potential side effects?

Potential side effects may include typical reactions to vaccines such as fever or rash, inflammation due to the immune response triggered by NAP protein production, and possible tissue damage at tumor sites where the virus is administered.

Trial Design

2Treatment groups

Experimental Treatment

Group I: Cohort 2 (multiple cycles MV-s-NAP)Experimental Treatment4 Interventions

Patients receive MV-s-NAP IT on day 1 of each cycle. Cycles repeat every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan, MRI, tumor biopsy and blood sample collection throughout the study.

Group II: Cohort 1 (single treatment MV-s-NAP)Experimental Treatment5 Interventions

Patients receive MV-s-NAP IT on day 1 in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan, MRI, tumor biopsy and blood sample collection throughout the study.
