Olaparib for Treatment of Metastatic Kidney Cancer in Patients with DNA Repair Gene Mutations, the ORCHID Study

Status: Active


This phase II trial studies how well olaparib works in treating patients with kidney cancer that has spread to other places in the body (metastatic) and have mutations in deoxyribonucleic acid (DNA) repair genes. It will also examine if olaparib is safe in these patients. PARPs are proteins that help repair damage to DNA, the genetic material that serves as the body’s instruction book. Changes (mutations) in DNA can cause tumor cells to grow quickly and out of control. PARP inhibitors like olaparib have been shown to keep PARP from working, so tumor cells may not be able to repair themselves, and may-stop growing.

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 electrocardiography (ECG) with corrected QT interval (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

Trial Objectives and Outline


I. To evaluate efficacy based on objective response or stable disease at 6 months to olaparib in patients with BAP-1 or other DNA repair gene mutation renal cell carcinoma (RCC).


I. To determine the safety/tolerability of olaparib in the RCC patient population.

II. To estimate the median progression-free survival.

III. To estimate the rate of objective response (complete response [CR] or partial response [PR]).


I. To investigate any association between acquired reversion mutations with clinical progression on olaparib.


Patients receive olaparib orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 28 days.
