Exclusion criteria
Exclusion criteria: • Participation in another clinical study with an investigational product during the last 6 months. • 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. • Medical or psychiatric conditions that compromise the patient's ability to give informed consent or to complete the protocol or a history of non-compliance • 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 (eg. ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil). The required washout period prior to starting study treatment 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 (eg. bosentan, efavirenz, modafinil). The required washout period prior to starting study treatment is 5 weeks for enzalutamide or phenobarbital and 3 weeks for other agents. • Obstruction of gastrointestinal tract • Active gastrointestinal bleeding • Myocardial infarction within 6 months prior to the study medication, and other clinically significant heart disease (e.g., unstable angina, congestive heart failure or uncontrolled hypertension) • Evidence of severe or uncontrolled systemic disease or any concurrent condition which in the investigator's opinion makes it undesirable for the patient to participate in the study or which would jeopardise compliance with the protocol • Combined hepatocellular carcinoma/cholangiocarcinoma is excluded. • ECG abnormalities including mean QT interval corrected for heart rate using Fridericia's formula (QTcF) =470 ms calculated from 3 ECGs (within 15 minutes at 5 minutes apart), resting ECG indicating uncontrolled, potentially reversible cardiac conditions, as judged by the investigator (eg., unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, electrolyte disturbances, etc.), or patients with congenital long QT syndrome. • Patients with myelodysplastic syndrome/acute myeloid leukaemia or with features suggestive of MDS/AML. • Patients with leptomeningeal carcinomatosis or symptomatic uncontrolled brain metastases. • Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication. • Any unresolved toxicity NCI CTCAE Grade =2 from previous anticancer therapy with the exception of alopecia and vitiligo • Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of IP. Note: Local surgery of isolated lesions for palliative intent is acceptable. • History of allogenic organ transplantation or double umbilical cord blood transplantation. • Active or prior documented autoimmune or inflammatory disorders. • History of active primary immunodeficiency. • Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice), hepatitis B (known positive HBV surface antigen (HBsAg) result), hepatitis C. • Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. • Receipt of live attenuated va
