Summary

This trial is testing a new cancer treatment to see if it is safe and effective.

Who is the study for?
This trial is for adults over 18 with early stage breast cancer, who are planning to have surgery and chemotherapy. It's specifically for those with a certain type of aggressive breast cancer (triple-negative) and tumors larger than 5 mm. Participants need to be in good health overall, as shown by their Karnofsky Performance status.
What is being tested?
The study tests the IRX-2 regimen's safety and how well patients respond before standard chemo. The regimen includes Cyclophosphamide, Indomethacin, Omeprazole, and Multivitamin given pre-operatively to see if it improves outcomes in triple-negative breast cancer cases.
What are the potential side effects?
Possible side effects from the IRX-2 regimen may include reactions related to immune system activation such as fever or fatigue; digestive issues due to Omeprazole; potential liver function changes from Indomethacin; and risks typically associated with Cyclophosphamide like hair loss or bladder irritation.

Trial Design

2Treatment groups
Experimental Treatment
Group I: IRX-2 Regimen -Triple Negative Breast CancerExperimental Treatment4 Interventions
Enrolled subjects with triple negative breast cancer will receive a single dose of cyclophosphamide (300 mg/m2) by IV infusion on Day 1. Also starting on Day 1 and continuing until Day 21, subjects will take daily oral indomethacin (25 mg three times each day), daily oral omeprazole (one tablet) and daily oral multivitamin containing 15-30 mg of zinc. On any 10 consecutive day period between Days 4-17, patients will receive two 1 mL subcutaneous periareolar injections of IRX-2.
Group II: IRX-2 Regimen -Early Stage Breast CancerExperimental Treatment4 Interventions
