A Phase 1 interventional study of Pharmacokinetic sampling and Olaparib tablet dosing in Solid Tumours, sponsored by AstraZeneca. Completed at 14 sites in 4 countries. Open to participants aged 18 Years to 130 Years. Per ClinicalTrials.gov, last updated 2016-10-17.
Sponsored by AstraZeneca · Phase 1 and Interventional
This is a 3-part study in patients with advanced solid tumours: Part A will assess the effect of itraconazole on the PK parameters of olaparib and will determine the effect of olaparib on the QT interval following single oral dosing; Part B will determine the effect of olaparib on the QT Interval following multiple oral dosing; Part C will allow patients continued access to olaparib after the PK and QT phases and will provide for additional safety data collection. A total of 48 patients are planned to be enrolled; at least 42 evaluable patients will be required to complete the study. Patients will participate as a single cohort in all parts of the study.
9,610 studies on the registry are indexed under Neoplasms; 2,508 are open to participants now.
