Olaparib in Treating Patients with Newly Diagnosed BRCA-Mutant Ovarian, Primary Peritoneal, or Fallopian Cancer before Surgery
This early phase I trial studies how well olaparib works in treating patients with newly diagnosed BRCA-mutant ovarian, primary peritoneal, or fallopian cancer before surgery. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

- Resting electrocardiogram (ECG) indicating uncontrolled, potentially reversible cardiac conditions, as judged by the investigator (e.g., unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, mean QT interval corrected for heart rate with Fridericia’s correction (QTcF) prolongation > 500 ms, electrolyte disturbances, etc.), or patients with congenital long QT syndrome
- Any unresolved toxicity (> CTCAE grade 2) from previous anti-cancer therapy, excluding alopecia
- History of hypersensitivity to olaparib or its excipients
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, active peptic ulcer disease or gastritis, active bleeding diatheses including any subject known to have evidence of acute or chronic hepatitis B, hepatitis C or human immunodeficiency virus (HIV) or otherwise immunocompromised subjects, or psychiatric illness/social situations that would limit compliance with study requirements or compromise the ability of the subject to give written informed consent
- History of leptomeningeal carcinomatosis
- Subjects who are pregnant and/or breast-feeding
- Any condition that, in the opinion of the investigator, would interfere with evaluation of study treatment or interpretation of subject safety or study results
- Symptomatic or uncontrolled brain metastases requiring concurrent treatment, inclusive of but not limited to surgery, radiation and/or corticosteroids. The subject can receive a stable dose of corticosteroids before and during the study as long as these were started at least 4 weeks prior to treatment. Patients with spinal cord compression unless considered to have received definitive treatment for this and evidence of clinically stable disease for 28 days
- Subjects with uncontrolled seizures
- Patients with myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of myelodysplastic syndrome/acute myeloid leukemia (MDS/AML)

Trial Objectives and Outline
I. To determine the feasibility of daily olaparib given in the neoadjuvant setting in women with primary advanced high grade non-mucinous epithelial ovarian, fallopian tube, or primary peritoneal cancer.
I. Estimate efficacy of olaparib given in the neoadjuvant setting using response rate (by Response Evaluation Criteria in Solid Tumors [RECIST] and other measures of anti-tumor activity such as CA125 and resolution of non-target lesions [ascites/pleural effusion]).
II. Estimate proportion of subjects able to proceed immediately to interval tumor reductive surgery (without chemotherapy).
III. Determine progression-free survival (PFS).
IV. Determine complete pathologic response rate at the time of surgery.
V. Determine the toxicity of daily olaparib given in the neoadjuvant setting.
VI. Evaluate the toxicity of chemotherapy given after neoadjuvant olaparib.
VII. Measure longitudinal symptom burden of study subjects treated with neoadjuvant olaparib and chemotherapy after olaparib.
I. Explore deoxyribonucleic acid (DNA) copy number and level of ribonucleic acid (RNA) and protein expression in homologous recombination-related pathways before and after treatment with olaparib in women with primary advanced high grade non-mucinous epithelial ovarian, fallopian tube, or primary peritoneal cancer.
II. Correlate molecular results to clinical endpoints including response and survival.
Patients receive olaparib orally (PO) twice daily (BID) on days 1-28. Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. After treatment, patients either undergo surgery then receive standard chemotherapy for up to 4 cycles or receive standard chemotherapy within 14 days for up to 4 cycles then undergo surgery in the absence of disease progression or unacceptable toxicity at the discretion of the treating physician.
After completion of study treatment, patients are followed up at 30 days.
