What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines the safety of a new treatment called IRX-2 for individuals with early-stage and triple-negative breast cancer. The study aims to assess patient response to chemotherapy following the IRX-2 treatment. Participants will take a combination of medications and receive injections over several weeks before their regular cancer treatment. This trial may suit someone with a confirmed breast cancer diagnosis who plans to undergo surgery and has not yet begun any cancer treatment. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot be on chronic anticoagulation (blood thinners) that can't be safely stopped for at least 2 days before starting the study treatment. It's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Research has shown that the IRX-2 treatment is safe for patients with early-stage and triple-negative breast cancer. In past studies, patients tolerated the treatment well, and no serious safety issues emerged. For early-stage breast cancer, studies demonstrated that IRX-2 led to positive changes in the immune system, which is encouraging. In triple-negative breast cancer, the treatment was also well tolerated, supporting further research. Although this trial remains in the early stages and safety tests continue, the current data is promising regarding its safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for breast cancer, which often include chemotherapy, radiation, or surgery, IRX-2 stands out due to its immunotherapy approach. This treatment uses a combination of a subcutaneous IRX-2 injection, which is believed to stimulate the immune system to fight cancer cells, along with supportive medications like cyclophosphamide, indomethacin, omeprazole, and zinc. Researchers are excited because IRX-2 directly targets the immune system, potentially offering a more targeted and less toxic alternative to conventional therapies. This approach could lead to improved outcomes for patients, especially those with triple-negative and early-stage breast cancer, where treatment options are currently limited.

What evidence suggests that this trial's treatments could be effective for breast cancer?

Research has shown that IRX-2, which participants in this trial may receive, may effectively treat triple-negative breast cancer. One study found that 83% of patients had a complete response with IRX-2, compared to 33% with another treatment. This suggests that IRX-2 might enhance the body's ability to fight cancer. For early-stage breast cancer, IRX-2 serves as another treatment option in this trial, proving safe and capable of positively affecting the immune system. Although the complete remission rate was low, patients tolerated the treatment well. Overall, these findings support further research into the effectiveness of IRX-2. ^{6 7 8 9 10}

Are You a Good Fit for This Trial?

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 Are the Treatments Tested in This Trial?

Interventions

• IRX-2

Trial Overview

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.

How Is the Trial Designed?

Group I: IRX-2 Regimen -Triple Negative Breast Cancer Experimental Treatment 4 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 Cancer Experimental Treatment 4 Interventions

Enrolled subjects with early stage 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.

Published Research Related to This Trial

In a trial involving 67 breast cancer patients undergoing neo-adjuvant therapy, pre-operative chemotherapy showed low side effects, with 79% of patients experiencing no hair loss and 74% reporting no gastrointestinal issues, despite the use of five different cytotoxic agents.

Response rates to pre-operative chemotherapy included 4% complete remission and 38% partial remission, indicating that while the treatment was generally well-tolerated, the effectiveness varied, and the study aims to identify which patients would benefit most from subsequent post-operative treatments.
