Hyperthermia and Olaparib in Treating Breast Cancer Patients With Chest Wall Recurrences

Recurrent Breast Carcinoma Clinical Trial

Official title: A Pilot Trial of Hyperthermia in Combination With Olaparib in Breast Cancer Patients With Chest Wall Recurrences

Status Active, not recruiting

Clinical Trial Summary

This phase I trial studies the side effects and best dose of olaparib when given with hyperthermia in treating patients with breast cancer that has come back in the chest wall. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hyperthermia treatment may kill or damage tumor cells by heating them to several degrees above normal body temperature. Giving olaparib and hyperthermia treatment may work better in treating patients with breast cancer that has come back in the chest well compared to standard of care.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To determine the dose limiting toxicities and maximum tolerated dose of olaparib given in combination with chest wall hyperthermia in patients with locally advanced or metastatic breast cancer with chest wall recurrences who have wild-type BRCA status (patients with germline BRCA mutations are excluded from this study).

SECONDARY OBJECTIVES:

I. To determine the local progression free survival (in months) for patients with chest wall recurrences defined as time to progression of disease on chest wall with olaparib with hyperthermia.

II. To determine the 1-year progression free survival (in months) for patients with chest wall recurrences treated with olaparib with hyperthermia.

III. To determine the best local overall response rate of chest wall after the combination of hyperthermia and olaparib.

IV. To determine the quality of life and pain scores before, during and after treatment as measured by the Edmonton Symptom Assessment System which includes a pain score and 8 other subjective measures of wellness for cancer patients (0 to 10).

EXPLORATORY OBJECTIVES:

I. To evaluate BRCA1/2 levels by immunohistochemistry and explore if hyperthermia induced BRCA1/2 expression.

II. To evaluate HR (homologous recombination) competency by RAD51 foci and explore if hyperthermia induces homologous recombination in breast tissue.

III. To explore deoxyribonucleic acid (DNA) damage as measured by gammaH2AX and comet assay in cells dissociated from biopsy tissues.

OUTLINE: This is a dose-escalation study of olaparib.

Patients receive olaparib orally (PO) twice daily (BID). Treatment continues for 4 weeks in the absence of disease progression and unacceptable toxicity. Beginning week 2, patients also undergo hyperthermia treatment over 1 hour twice weekly for 3 weeks in the absence of disease progression and unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 12 months. ;
