入选标准
- •Males and females ≥18 years of age (at the time consent is obtained).

- •Male patients must use a condom during treatment and for 3 months after the last dose of study drug 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 (see 5.3.1) if they are of childbearing potential. Male patients should not donate sperm throughout the period of taking study drug and for 3 months following the last dose of study drug.

- •Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures
- •Written informed consent provided.
- •Performance Status score of 0 or 1 according to the Eastern Cooperative Oncology Group (ECOG) scale (Appendix A).
- •Subject must have archival tumour tissue available for central laboratory testing of alterations in DDR genes or willing to undergo a fresh tumour biopsy.
- •Histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas.
- •Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Provision of signed and dated, written informed consent form prior to any mandatory study specific procedures, sampling, and analyses.
- •Histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas with alterations in DNA damage repair genes.
- •Presence of alterations in DDR genes in tumour tissue or blood (somatic) or blood and saliva (germinal) sample previously determined by a local assay at any time prior to Screening or by the central laboratory.
- •Patients must have received a minimum of 1 line of chemotherapy for metastatic disease and a maximum of 2 lines. Patients who have received adjuvant treatment and have recurrence within 6 months of completion of the adjuvant or neoadjuvant treatment, is counted as first line chemotherapy.
排除标准
- •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).
- •Immunocompromised patients, e.g., patients who are known to be serologically positive for human immunodeficiency virus (HIV).
- •Patients with known active hepatitis (i.e., Hepatitis B or C).
- •Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent.
- •Any pre-existing medical condition of sufficient severity to prevent full compliance with the study.
- •Have received previously treatment with PARP inhibitors or PDL-1 inhibitors (including durvalumab).
- •Patients receiving any systemic chemotherapy or radiotherapy (except for palliative reasons) within 3 weeks prior to study treatment.
- •Concomitant chemotherapy, hormonal therapy, immunotherapy, or any other form of cancer treatment.
- •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, 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.
- •Major surgery within 2 weeks of starting study treatment and patients must have recovered from any effects of any major surgery.
- •Uncontrolled, clinically significant, symptomatic cardiovascular disease within 6 months before enrolment, including myocardial infarction, unstable angina, grade 2 or greater peripheral vascular disease, cerebrovascular accident, transient ischemic attack, congestive heart failure, or arrhythmias not controlled by outpatient medication.
- •Previous allogenic bone marrow transplant or double umbilical cord blood transplantation (dUCBT).
- •Concurrent treatment or treatment within 4 weeks of study entry with any other investigational agent.
- •Patients with a known hypersensitivity to olaparib, durvalumab or any of the excipients of the product.
- •Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.
- •Female patients who are lactating and breastfeeding or have a positive pregnancy test during the Screening Period.
- •Resting ECG indicating uncontrolled, potentially reversible cardiac conditions, as judged by the investigator (e.g., unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, QTcF prolongation >500 ms, electrolyte disturbances, etc.), or patients with congenital long QT syndrome.
- •Persistent toxicities (≥Common Terminology Criteria for Adverse Event (CTCAE) grade 2) caused by previous cancer therapy, excluding alopecia.
- •Patients with myelodysplastic syndrome/acute myeloid leukaemia or with features suggestive of MDS/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.
- •Patients considered a poor medical condition 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, 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.
- •Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication.
- •Patients with an active infection.
结局指标
主要结局
Overall Response Rate (ORR) defined as the percentage of patients with an investigator-assessed complete (CR) or partial response (PR) according to Response Evaluation Criteria in Solid tumours (RECIST) v1.1.
Overall Response Rate (ORR) defined as the percentage of patients with an investigator-assessed complete (CR) or partial response (PR) according to Response Evaluation Criteria in Solid tumours (RECIST) v1.1.
次要结局
- PFS defined as the time from initial date of study treatment to the date of objective disease progression according to RECIST 1.1 criteria or death (due to any cause), whichever occurs first.
- OS defined as the time from the initial date of the study treatment to the date of death (due to any cause), with patients alive or lost to follow-up at the analysis data cut-off date censored at their last contact date.
- DoR defined as time from first objective response to disease progression per RECIST 1.1 criteria or death (due to any cause). For patients with response who have not progressed or died at last observation, duration of response will be censored at their last evaluable disease assessment date.
- DCR defined as the percentage of patients who achieve complete response, partial response or stable disease.
- Assessment of AEs graded by NCI CTCAE v5.0, vital signs and evaluation of laboratory parameters.
