OLAParib COmbinations — OLAPCO  

Cancer Clinical Trial

Official title: A Phase II Study of the PARP Inhibitor Olaparib (AZD2281) Alone and in Combination With AZD1775, AZD5363, or AZD6738 in Advanced Solid Tumors

Status Terminated

Clinical Trial Summary

The primary objective of this phase II trial is to determine tumor overall response rate (ORR) in molecularly selected patients with measurable disease as assessed by the Response Evaluation Criteria in Solid Tumors (RECIST), before versus after 16 weeks of treatment across tumor types in each arm of the study.

Clinical Trial Description

This is a phase II signal-searching study in a range of tumor types with the potential to identify novel tumor indications for combination therapy with olaparib that can subsequently be explored in dedicated studies. Patients will be enrolled in this study based on molecular markers from genetic profiling performed on their tumors prior to study entry (outside of protocol). The trial will also identify genetic determinants of response and resistance.

Patients with tumors harboring damaging mutations in Homologous - DNA repair (HDR) genes or mutations such as ATM, CHK2, MRN (MRE11/NBS1/RAD50), CDKN2A/B and APOBEC will be treated with olaparib or olaparib and AZD6738. Enrollment to the olaparib monotherapy arm will be completed prior to commencement of enrollment to the olaparib and AZD6738 arm. Patients with tumors harboring IDH1/IDH2 mutations will be treated with olaparib. Patients with tumors harboring either TP53 or KRAS mutations or mutations in KRAS and TP53 will be treated with AZD1775 plus olaparib. Patients with tumors harboring PTEN, PIK3CA, AKT, or ARID1A mutations or other molecular aberrations leading to dysregulation of the PI3K/AKT pathway will be treated with AZD5363 plus olaparib. ;
