• Creatinine clearance estimated using the Cockcroft-Gault equation of >= 51 mL/min.
• 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.
• Total bilirubin =< 2 x ULN or =< 3 x ULN if Gilbert's disease).
• Forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and carbon monoxide diffusing capacity (DLCOc) >= 50% of predicted.
• Left ventricular ejection fraction (LVEF) >= 40%, no uncontrolled arrhythmias or symptomatic cardiac disease.
• Eastern Cooperative Oncology Group (ECOG) performance status < 2.
• Provision of informed consent prior to any study specific procedures.
• Patients must have a life expectancy >= 16 weeks.
• Postmenopausal or evidence of non-childbearing status for women of childbearing potential: negative urine or serum pregnancy test within 28 days and within 72 hours of study treatment and confirmed prior to receiving treatment on this study. Patients with positive results will be removed from the study. Postmenopausal is defined as one of the following: * Amenorrheic for 1 year or more following cessation of exogenous hormonal treatments. * Luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels in the postmenopausal range for women under 50. * Radiation-induced oophorectomy with last menses > 1 year ago. * Chemotherapy-induced menopause with > 1 year interval since last menses. * Surgical sterilization (bilateral oophorectomy or hysterectomy). * Female patients must agree to use a highly effective birth control method while on study and for at least 1 month after the last dose of study drug(s).
• 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.
• Prior apheresis of >= 3 million CD34+ cells/Kg.
• Eligibility for ASCT is determined by the above inclusion criteria.

Exclusion Criteria

• Persistent toxicities (> Common Terminology Criteria for Adverse Events [CTCAE] grade 2) caused by previous cancer therapy, excluding alopecia.
• Prior whole brain irradiation.
• Active hepatitis B, either active carrier (hepatitis B surface antigen [HBsAg] +) or viremic (hepatitis B virus [HBV] deoxyribonucleic acid [DNA] >/= 10,000 copies/mL, or >= 2,000 IU/mL).
• Evidence of either cirrhosis or stage 3-4 liver fibrosis in patients with chronic hepatitis C or positive hepatitis C serology.
• Active infection requiring parenteral antibiotics.
• Patients who are known to be serologically positive for human immunodeficiency virus (HIV).
• Patients receiving any systemic chemotherapy or radiotherapy (except for palliative reasons) within 3 weeks prior to study treatment.
• Pregnancy.
• Other malignancy within the last 5 years except: adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS), stage 1, grade 1 endometrial carcinoma, or other solid tumors.
• Resting electrocardiography (ECG) with correct QT interval (QTc) > 470 msec on 2 or more time points within a 24 hour period or family history of long QT syndrome.
• Concomitant use of known strong CYP3A inhibitors (eg. 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 (eg. phenobarbital, enzalutamide, 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 enzalutamide or phenobarbital and 3 weeks for other agents.
• Patients with myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML).
• Patients with symptomatic uncontrolled brain metastases. A scan to confirm the absence of brain metastases is not required. The patient 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.
• Major surgery within 2 weeks of starting study treatment and patients must have recovered from any effects of any major surgery.
• Uncontrolled 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, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on high resolution computed tomography (HRCT) scan or any psychiatric disorder that prohibits obtaining informed consent.
