Olaparib Before Surgery in Treating Participants With Localized Prostate Cancer
Open-Label, Pilot Study of Olaparib as a Neoadjuvant Therapy for Patients Undergoing Prostatectomy for Localized Prostate Cancer
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
PRIMARY OBJECTIVE:
I. To assess the pathological complete response rate following olaparib when administered as neoadjuvant therapy prior to prostatectomy in patients with localized prostate cancer containing homozygous or complementary deoxyribonucleic acid [DNA] repair deficiency.
SECONDARY OBJECTIVE:
I. To determine the rate of positive surgical margins, extracapsular extension, positive seminal vesicles and lymph nodes at the time of prostatectomy.
OUTLINE:
Participants receive olaparib orally twice daily for 90 days in the absence of unacceptable toxicity. Beginning 1 day after last olaparib dose, participants undergo radical prostatectomy.
After completion of study treatment, participants are followed up for 30 days.

Description
Inclusion Criteria:
- Provision of informed consent prior to any study specific procedures.
- Histologically confirmed adenocarcinoma of the prostate without morphologic neuroendocrine differentiation or small cell features.
- The presence of homologous recombination deficiency defined by either; A) Inherited pathogenic variant of BRCA2, ATM, BRCA1, PALB2 by a Clinical Laboratory Improvement Act (CLIA) level germline assay or B) have evidence by somatic sequencing using a CLIA level assay of biallelic inactivation of BRCA1, BRCA2, PALB2, FANCA or biallelic inactivation or monoallelic inactivating mutation of ATM. It is anticipated that the majority of patients will be germline carriers of a pathogenic variant of BRCA1, BRCA2 or ATM. Other germline mutations will be considered at investigator's discretion.
- Must be candidates for radical prostatectomy and considered surgically resectable by urologic evaluation.
- No evidence of metastatic disease or nodal disease as determined by radionuclide bone scans and computed tomography (CT)/magnetic resonance imaging (MRI); non-pathological lymph nodes must be less than 20 mm in the short (transverse) axis.
- Provided written authorization for use and release of health and research study information.
- Hemoglobin >= 10.0 g/dL with no blood transfusion in the past 28 days.
- Absolute neutrophil count (ANC) >= 1.5 x 10^9/L (within 28 days prior to administration of study treatment).
- Platelet count >= 100 x 10^9/L (within 28 days prior to administration of study treatment).
- Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) (within 28 days prior to administration of study treatment).
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) / alanine aminotransferase (ALT) (serum glutamic pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal unless liver metastases are present in which case they must be =< 5 x ULN (within 28 days prior to administration of study treatment).
- Patients must have creatinine clearance estimated using the Cockcroft-Gault equation of >= 51 mL/min (within 28 days prior to administration of study treatment).
- Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
- Patients must have a life expectancy >= 16 weeks.
- Male patients and their partners, who are sexually active and of childbearing potential, must agree to the use of two highly effective forms of contraception in combination throughout the period of taking study treatment and for 3 months after last dose of study drug(s) to prevent pregnancy in a partner.
- Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations.
Exclusion Criteria:
- Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).
- Any previous treatment with PARP inhibitor, including olaparib.
- Other malignancy within the last 5 years except: adequately treated non-melanoma skin cancer, or other solid tumors including lymphomas (without bone marrow involvement) curatively treated with no evidence of disease for >= 5 years.
- Resting electrocardiogram (ECG) with corrected QT interval (QTc) > 470 msec on 2 or more time points within a 24-hour period or family history of long QT syndrome.
- Patients receiving any systemic chemotherapy, hormonal therapy or radiotherapy.
- Concomitant use of known strong CYP3A inhibitors (e.g. itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (e.g. ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil). The required washout period prior to starting olaparib is 2 weeks.
- Concomitant use of known strong (e.g. phenobarbital, phenytoin, rifampicin, rifabutin, rifapentine, carbamazepine, nevirapine and St John's wort) or moderate CYP3A inducers (e.g. bosentan, efavirenz, modafinil). The required washout period prior to starting olaparib is 5 weeks for phenobarbital and 3 weeks for other agents.
- Patients with myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of myelodysplastic syndromes (MDS)/acute myeloid leukemia (AML).
- Major surgery within 2 weeks of starting study treatment and patients must have recovered from any effects of any major surgery.
- Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, extensive interstitial bilateral lung disease on high resolution computed tomography (HRCT) scan or any psychiatric disorder that prohibits obtaining informed consent.
- Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication.
- Immunocompromised patients, e.g., patients who are known to be serologically positive for human immunodeficiency virus (HIV).
- Patients with a known hypersensitivity to olaparib or any of the excipients of the product.
- Patients with known active hepatitis (i.e., hepatitis B or C) due to risk of transmitting the infection through blood or other body fluids.
- Previous allogenic bone marrow transplant or cord blood transplantation.
- Whole blood transfusions in the last 120 days prior to entry to the study (packed red blood cells and platelet transfusions are acceptable).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pathologic Complete Response (pCR) Rate
Time Frame: At time of prostatectomy (at 12 weeks)
|
Percent of patients who achieve a pCR at the time of prostatectomy, after 12 weeks of neoadjuvant therapy with olaparib.
PCR is defined as the absence of morphologically identifiable carcinoma in the prostatectomy specimen.
Assessment will be based on the recommendations of the International Society of Urological Pathology (ISUP).
|
At time of prostatectomy (at 12 weeks)
|
Number of Participants With Adverse Events
Time Frame: Up to 30 days after the last dose of olaparib
|
Will be evaluated according to Common Terminology Criteria for Adverse Events (CTCAE).
|
Up to 30 days after the last dose of olaparib
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Rate of Positive Surgical Margins
Time Frame: At time of prostatectomy (at 12 weeks)
|
The rate of detectable tumor in pathology specimens obtained at prostatectomy.
|
At time of prostatectomy (at 12 weeks)
|
Stage of Disease
Time Frame: At time of prostatectomy (at 12 weeks)
|
Pathology specimens obtained at prostatectomy will be assessed using the tumor, lymph node, and metastasis (TNM) staging system for prostate cancer. Stage Stage 2 represents patients with disease without evidence of extension outside of the prostate Stage 3 represents patients with disease which has penetrated the capsule of the prostate |
