Summary

This trial is testing radiation therapy with or without olaparib to see which is more effective in treating inflammatory breast cancer.

Who is the study for?

This trial is for adults with inflammatory breast cancer without distant metastases who have completed neoadjuvant chemotherapy and mastectomy. They must not have had prior radiation to the chest or certain drug treatments during the study, agree to contraception if of childbearing potential, and cannot be breastfeeding. Participants need proper organ function, no uncontrolled diseases or recent major surgeries, and can't be on strong CYP3A inhibitors/inducers.

What is being tested?

The trial is testing whether adding Olaparib (a PARP inhibitor that prevents cancer cells from repairing DNA damage) to standard radiation therapy improves outcomes in patients with inflammatory breast cancer compared to radiation alone. Patients are randomly assigned to one of these two treatment options.

What are the potential side effects?

Olaparib may cause nausea, vomiting, fatigue, anemia (low red blood cell counts), neutropenia (low white blood cell counts), thrombocytopenia (low platelet counts), digestive issues like diarrhea or constipation, and increased risk of developing other cancers such as leukemia.

Trial Design

2Treatment groups

Experimental Treatment

Active Control

Group I: Group I (olaparib, radiation therapy)Experimental Treatment4 Interventions

Patients receive olaparib PO BID the day before standard RT commences (Day 0) and throughout the RT course until the last day of RT administration. Olaparib is also continued on weekends (routine days without RT) throughout the RT course. Patients undergo standard radiation therapy 5 days per week for 6 weeks in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection throughout the study.

Group II: Group II (radiation therapy)Active Control3 Interventions

Patients undergo standard radiation therapy 5 days per week for 6 weeks in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection throughout the study.
