Study of Olaparib in Metastatic Renal Cell Carcinoma Patients With DNA Repair Gene Mutations
Bu çalışma, Olaparib adlı ilacı, DNA onarım genlerinde (BRCA1, BRCA2, ATM, PALB2 gibi) mutasyon taşıyan metastatik böbrek hücreli karsinom (metastatic renal cell carcinoma) hastalarında değerlendirmektedir. Çalışmaya, daha önce anti-anjiyojenik bir ajan veya bağışıklık kontrol noktası inhibitörü ile en az bir tedavi almış, 18 yaş ve üzeri hastalar katılmaktadır. Çalışma Faz 2 aşamasında yürütülmekte ve halen katılımcı almaktadır.

Inclusion Criteria: * Willing and able to provide written informed consent. Provision of informed consent is required prior to any study procedures. * Patients aged 18 years of age or older. * Histological proof of renal cell carcinoma (both clear cell and non-clear cell allowed). * Metastatic (AJCC Stage IV) renal cell carcinoma. * Somatic or germline mutation in BAP-1, ATM, BRCA1, BRCA2, PALB2, CHEK2, BRIP1, RAD51C, BARD1, CDK12, CHEK1, FANCL, PP2R2A, RAD51B, RAD51D, or RAD54L as documented by a clinical CLIA-grade, tissue, saliva or blood-based genetic test. * At least one prior treatment with an anti-angiogenic agent or immune checkpoint inhibitor. * Any number of prior systemic therapies is allowed (cytokine, anti-angiogenic, mTOR, immune checkpoint blockage or clinical trial). * Must have measurable disease as defined by RECIST 1.1 criteria. * Participants must have normal organ and bone marrow function measured within 28 days prior to administration of study treatment as defined below: * Hemoglobin ≥ 10.0 g/dL with no blood transfusion in the past 28 days * Absolute neutrophil count (ANC) ≥ 1.5 x 10\^9/L * Platelet count ≥ 100 x 10\^9/L * Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN) * Aspartate aminotransferase (AST) (Serum Glutamic Oxaloacetic Transaminase (SGOT)) / Alanine aminotransferase (ALT) (Serum Glutamic Pyruvate Transaminase (SGPT)) ≤ 2.5 x institutional ULN unless liver metastases are present in which case they must be ≤ 5 x ULN. Note: Patients with elevations in bilirubin, AST, or ALT should be thoroughly evaluated for the etiology of this abnormality prior to entry and patients with evidence of viral infection should be excluded. * Patients must have a creatinine clearance ≥ 40 mL/min calculated by Cockroft-Gault formula or 24 hour urine test. * ECOG PS ≤ 1. * Participants 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 of study treatment and confirmed prior to treatment on day 1. Postmenopausal is defined as: * Amenorrheic for 1 year or more following cessation of exogenous hormonal treatments. * Luteinizing hormone (LH) and Follicle stimulating hormone (FSH) levels in the post menopausal range for women under 50 years old. * 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). * Male patients must use a condom during treatment and for 3 months after the last dose of olaparib when having sexual intercourse with a pregnant woman or with a woman of childbearing potential. Female partners of male patients should also use a highly effective form of contraception if they are of childbearing potential. Exclusion Criteria: * Other malignancy unless curatively treated with no evidence of disease for ≥ 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. Patients with a history of localized triple negative breast cancer may be eligible, provided they completed their adjuvant chemotherapy \> 3 years prior to registration, and that the patient remains free of recurrent or metastatic disease. * 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. * Previous allogenic bone marrow transplant or double umbilical cord blood transplantation (dUCBT). * Judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements. * Breast feeding women. * Use of any prohibited concomitant medications within the prior 2 weeks. * Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site). * Participation in another clinical study with an investigational product during the last 2 weeks. * Patients receiving any systemic chemotherapy or radiotherapy (except for palliative reasons) within 3 weeks prior to study treatment. * Any previous treatment with PARP inhibitor, including olaparib. * Resting ECG with QTc \> 500 ms and/or indication of uncontrolled cardiac conditions, as judged by the investigator (e.g. unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, electrolyte disturbances, etc.), or patients with congenital and/or family history of long QT syndrome. * 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. During the study, if co-administration of a strong or moderate inhibitor is required because there is no suitable alternative medication, exception to this criterion may be allowed with a suitable dose reduction of olaparib. * Concomitant use of known strong CYP3A inducers (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 or enzalutamide and 3 weeks for other agents. * Persistent toxicities (\> Common Terminology Criteria for Adverse Event (CTCAE) grade 2) caused by previous cancer therapy, excluding alopecia. * Patients with myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) or with features suggestive of MDS/AML. * Major surgery within 2 weeks of starting study treatment and patients must have recovered from any effects of any major surgery. * 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. * 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). * Known hypersensitivity to olaparib or any of the excipients of the product. * Known active hepatitis (i.e. Hepatitis B or C) due to risk of transmitting the infection through blood or other body fluids. * No packed red blood cells and/or platelet transfusions within the last 28 days prior to study entry.
