Study Summary

This trial is testing a new cancer treatment that uses a combination of drugs and electrical pulses to kill tumors. The study will enroll people with a certain type of breast cancer that has spread to the skin.

Who is the study for?
This trial is for adults with inoperable locally advanced or metastatic Triple-Negative Breast Cancer (TNBC). Participants must have measurable disease, no prior systemic therapy in the metastatic setting for Cohort 2, and at least one prior line of treatment for Cohort 1. They should be able to provide a tumor biopsy, have an ECOG performance status of 0-1, and expect to live at least six more months. Women who can get pregnant must test negative for pregnancy and agree to use contraception.Check my eligibility
What is being tested?
The study tests Tavo (tavokinogene telseplasmid) with electroporation plus Pembrolizumab alone (Cohort 1), or combined with chemotherapy options like nab-paclitaxel or gemcitabine plus carboplatin (Cohort 2). It's a Phase 2 trial where all participants receive the experimental treatments without being compared to a control group receiving standard care.See study design
What are the potential side effects?
Possible side effects include reactions related to immune system activation such as inflammation in various organs, infusion-related reactions from the drugs administered intravenously, fatigue, blood disorders that may affect clotting or immunity levels, potential nerve damage from chemotherapy agents leading to numbness or tingling sensations.
