Summary

This phase II trial studies how well radiation therapy with or without olaparib works in treating patients with inflammatory breast cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether radiation therapy with or without olaparib may work better in treating patients with inflammatory breast cancer.

Objectives

PRIMARY OBJECTIVES:
I. To compare the Invasive Disease-Free Survival (IDFS) of patients with inflammatory breast cancer receiving concurrent administration of olaparib with standard doses of radiotherapy to the chest wall and regional lymph nodes compared to standard doses of radiotherapy alone to the chest wall and regional lymph nodes.

SECONDARY OBJECTIVES:
I. To compare the effect of concurrent administration of olaparib with radiotherapy versus radiotherapy alone on improvement in locoregional control (measured by Locoregional Recurrence-Free Interval), Distant Relapse-Free Survival, and Overall Survival in inflammatory breast cancer patients.

ADDITIONAL OBJECTIVES:
I. To collect tissue and whole blood for processing and banking in anticipation of future correlative studies in this patient population.

OUTLINE: Participants are randomized to 1 of 2 groups.

GROUP I: Participants receive olaparib orally (PO) twice daily (BID) the day before standard radiation therapy (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. Participants undergo radiation therapy 5 days per week for 6 weeks in the absence of disease progression or unaccepted toxicity.

GROUP II: Participants undergo standard radiation therapy 5 days per week for 6 weeks in the absence of disease progression or unaccepted toxicity.

After completion of study treatment, participants are followed up within 5 weeks, then every 3 months until 3 years after registration, and then every 6 months for up to 8 years after registration.
**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments.
