Study Summary

This trial tests a new combo of drugs to treat advanced triple-negative breast cancer.

Who is the study for?
Adults with metastatic triple-negative breast cancer can join this trial. They should have normal organ function, no severe neuropathy, and be in good physical condition. Prior treatments for cancer are okay if they've recovered from the side effects. People with certain viral infections must have them under control.Check my eligibility
What is being tested?
The trial is testing ASTX727 (a combo of decitabine and cedazuridine) added to standard chemotherapy (paclitaxel) and immunotherapy (pembrolizumab). It aims to find a safe dose that might help shrink or stabilize cancer better than the usual treatment alone.See study design
What are the potential side effects?
Possible side effects include reactions related to immune system activation, nerve damage from paclitaxel, blood cell count changes due to decitabine, and gastrointestinal issues affecting medication absorption.

Experimental Treatment
Group I: Treatment (ASTX727, paclitaxel, pembrolizumab)Experimental Treatment7 Interventions
Patients receive ASTX727 PO on days 1-4, paclitaxel IV over 1 hour on days 1, 8, and 15, and pembrolizumab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo collection of blood samples and CT and/or MRI throughout the trial. Patients in the dose-expansion phase also undergo a tumor biopsy during screening and day 1 of the treatment cycle 2 of the study. Patients will be followed every 3 months for 2 years after treatment and then every 6 months for an additional 3 years or until death, whichever occurs first.
