ATARI is a multi-centre, open-label, multiple two-stage parallel cohorts phase II clinical trial for patients with relapsed gynaecological cancers, with ARID1A-deficient ('loss') and no loss.~The trial tests the ATR inhibitor drug AZD6738 and a PARP inhibitor drug olaparib to assess the response in groups of patients selected based on their cancer cell subtype and the presence of an abnormality in ARID1A.~The treatment groups are: 1A - Women with clear cell subtype with (ovarian/uterus) ARID1A loss treated with AZD6738. 1B - Women with clear cell subtype with (ovarian/uterus) ARID1A loss treated with AZD6738 + olaparib. 2 - Women with clear cell subtype (ovarian/uterus) with no ARID1A loss treated with AZD6738 and olaparib. 3 - Women with other rare gynaecological cancers (carcinosarcoma, cervical, endometrioid type) irrespective of ARID1A loss treated with AZD6738 and olaparib.
