-
Histologically confirmed progressive or recurrent gynaecological carcinomas of the following histological subtypes:
- Ovarian and endometrial clear cell (>50% clear cell carcinoma with no serous differentiation)
- Endometrioid
- Cervical - adenocarcinomas and squamous
- Carcinosarcomas Note: patients who have an original diagnosis based on cytology only will not be eligible for entry into the study unless a biopsy confirming above histology is performed
- Histological tissue specimen (tissue block or 8-10 unstained slides) must be available (specimen can be the sample at diagnosis or taken at relapse). Otherwise, a biopsy must be carried out to obtain sufficient tissue for histological assessment
- Evidence of radiological disease progression since last systemic anti-cancer therapy and prior to trial entry
- Patients who have progressed after ≥1 prior platinum containing regimen. Platinum-based therapy does not need to be the last treatment prior to study entry. For patients who have disease progression within 6 months of last dose of a platinum-containing regime, no more than two further lines of systemic therapy are permitted prior to trial entry
- Measurable disease by RECIST criteria v1.1, which can be accurately assessed at baseline by CT (or MRI where CT is contradicted or unclear). Patients with CA125 progression in the absence of measurable disease will NOT be eligible
- ECOG performance status 0 or 1 with no deterioration over the previous 2 weeks
- Life expectancy > 16 weeks
-
Adequate hepatic, bone marrow, coagulation and renal function as defined by the following values within 14 days prior to starting treatment:
- Haemoglobin ≥10.0 g/dL with no blood transfusion in the past 14 days
- Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
- Platelet count ≥ 100 x 109/L with no platelet transfusion in the past 28 days
- Creatinine clearance ≥51 mL/min (estimated using Cockcroft-Gault equation or measured GFR clearance test as appropriate); • Total bilirubin ≤1.5 x ULN (where bilirubin rise > 1.5 x ULN due to Gilbert's syndrome a conjugated bilirubin ≤1.5 x ULN is required)
- Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤2.5 x ULN if no demonstrable liver metastases or ≤5 times ULN if patient has documented liver metastases
- No significant medical illness which in the opinion of the Investigator would preclude entry to ATARI
-
Women of child-bearing potential who are confirmed NOT to be pregnant. This should be evidenced by a negative urine or serum pregnancy test within 72 hours prior to start of trial treatment. Patients will be considered to be not of child-bearing potential if they are:
- Post-menopausal - defined as aged more than 50 years and amenorrhoeic for at least 12 months following cessation of all exogenous hormonal treatments, OR women under 50 years old who have been amenorrhoeic for at least 12 months following cessation of all exogenous hormonal treatments and have serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and plasma oestradiol levels in the post-menopausal range for the institution
- Able to provide documentation of irreversible surgical sterilisation by hysterectomy, bilateral oophorectomy or bilateral salpingectomy but not tubal ligation
- Radiation or chemotherapy-induced oophorectomy or menopause with > 1 year since last menses
- Patients with prior synchronous tumours or history of prior malignancy are eligible provided that there is biopsy evidence that the disease measurable on CT and/or MRI is of the histological subtypes stated in 1
- Willingness to commit to scheduled visits, treatments plans, laboratory tests and study procedures
- Able to swallow, absorb, retain oral medication
- Able to provide written, informed consent

| Critètes d'exclusion |
- Prior treatment with ATR or PARP inhibitors, including AZD6738 and olaparib
-
Patients receiving, or having received:
- cytotoxic treatment for their malignancy within 21 days prior to Cycle 1 Day 1
- exposure to a small molecule IP within 30 days or 5 half-lives (whichever is longer) prior to Cycle 1 Day 1. The minimum washout for immunotherapy is 42 days
- treatment with bevacizumab within 30 days prior to Cycle 1 Day 1
- palliative radiotherapy within 21 days prior to Cycle 1 Day 1
- Treatment with any other investigational medicinal product within the 4 weeks prior to trial entry

Note these include common azole antifungals, macrolide antibiotics and other medications (Refer to Section 11 and Appendix A5 for further details)
- Pregnant or lactating women.
- Women of childbearing age and potential who are not willing to use one highly effective form of contraception and a condom as detailed in Section 5.5
- Any other malignancy which has been active or treated within the past three years, with the exception of cervical intra-epithelial neoplasia and non-melanoma skin cancer
