Summary

This trial is testing a new cancer treatment for patients with triple negative breast cancer that has spread or can't be removed by surgery. The treatment boosts the immune system to recognize and destroy cancer cells.

Who is the study for?
This trial is for adults with triple negative breast cancer that has spread or can't be surgically removed. Participants need at least two target lesions, normal liver and blood function, and must use birth control if of child-bearing potential. Exclusions include active infections, certain heart conditions, immunodeficiency disorders, recent vaccine administration, and brain metastases.
What is being tested?
The trial tests a combination of dendritic cell-based treatment to boost the immune system's ability to fight cancer cells and pembrolizumab—an immune checkpoint inhibitor—to potentially enhance this effect. The goal is to see if these treatments together can reduce symptoms and improve life quality in patients.
What are the potential side effects?
Possible side effects may include reactions related to the immune system such as flu-like symptoms, fatigue, skin reactions; organ inflammation; increased risk of infection; allergic responses to pembrolizumab components; plus any discomfort from procedures like leukapheresis (white blood cell removal) or biopsies.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Treatment (ST-alpha-DC1, pembrolizumab)Experimental Treatment6 Interventions
Patients undergo leukapheresis over 90 minutes. Patients then receive ST-alpha-DC1 IT on days 1, 8, and 50 in the absence of disease progression or unacceptable toxicity. Patients also receive pembrolizumab IV on days 8, 29, 50, and 71 in the absence of disease progression or unacceptable toxicity. Patients who are receiving clinical benefit from treatment at the end of day 85, may continue to receive pembrolizumab IV every 3 weeks beyond the 4 study doses. Patients also undergo tumor biopsies on days 1, 8, and 50 and CT scans at baseline and days 50 and 85.
