Summary

This trialis researching Immunotherapy as a possible adjuvant treatment for Triple Negative Breast Cancer. It will look at safety, tolerability, and immune response.

Who is the study for?
This trial is for women over 18 with Stage II or III Triple Negative Breast Cancer who've finished their planned cancer therapy. They must not have HIV, hepatitis B/C, autoimmune diseases, or certain medical conditions that could affect the study. Participants need to be HLA-A2 positive and willing to use birth control if they can have children.
What is being tested?
The trial tests a combination of PVX-410 vaccine and Durvalumab (MEDI4736), a PD-L1 inhibitor, as additional treatment after standard care for breast cancer. It aims to assess safety, tolerability, and how well the immune system responds to these treatments in patients.
What are the potential side effects?
Possible side effects include reactions at the injection site from the vaccine and immune-related issues due to Durvalumab such as inflammation in various organs. Fatigue and digestive problems may also occur.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
Dose Limiting Toxicity Rate of PVX-410 in Combination With Durvalumab
Secondary study objectives
Adverse events according to Common Toxicology Criteria for Adverse Events (CTCAE 4.0) will be assessed for the PVX-410 vaccine regimen alone versus PVX-410 vaccine regimen plus durvalumab
Disease-Free Survival
