Phase II Trial of AZD6738 Alone and in Combination With Olaparib
This phase II trial studies how well ATR kinase inhibitor AZD6738 works alone or in combination with olaparib in treating participants with renal cell carcinoma, urothelial carcinoma, all pancreatic cancers, or other solid tumors that have spread to nearby tissue or lymph nodes or other parts of the body. ATR kinase inhibitor AZD6738 and olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not known if giving ATR kinase inhibitor AZD6738 with or without olaparib may work better in treating participants with solid tumors.
Phase II Trial of AZD6738 Alone and in Combination With Olaparib in Patients With Selected Solid Tumor Malignancies
- To assess objective response rate (ORR) of ATR kinase inhibitor AZD6738 (AZD6738) monotherapy and AZD6738 + olaparib by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.
- To determine the median duration of response (DOR) in each study arm. II. To determine the median progression-free survival and progression-free survival rate at 6 and 12 months in each study arm.
III. To further characterize the safety and tolerability profile of AZD6738 alone and in combination with olaparib.

- Patients must provide written informed consent prior to performance of study-specific procedures or assessments.
- Histologically confirmed locally advanced or metastatic solid tumor malignancy with by tumor type as specified below:
- Renal cell carcinoma with clear cell component (Cohort A): Patients must have prior progression on or following, intolerance of, or patient refusal to receive vascular endothelial growth factor (VEGF)-targeting tyrosine kinase inhibitor and immune checkpoint blockade.
- Urothelial carcinoma (Cohort B). Patients must have prior progression on or following, intolerance of, or patient refusal to receive platinum chemotherapy and immune checkpoint blockade.
- All pancreatic cancers (Cohort C). Patients must have prior progression on or following, intolerance of, or patient refusal to receive fluorouracil (5-FU), gemcitabine, and irinotecan-based chemotherapy.

- Evidence of clinical or radiographic progression prior to study entry.

- Patients must be at least 3 weeks or 5 half-lives (whichever is shorter) from last standard or experimental non-cytotoxic therapy prior to first dose of protocol therapy. Patients must be > 21 days from last dose of cytotoxic chemotherapy prior to C1D1. The minimum wash-out period for immunotherapy is 42 days prior to C1D1.
- Radiation therapy must be completed > 7 days prior to course 1 day 1 (C1D1) or > 28 days prior to C1D1 for patients receiving radiation to more than 30% of bone marrow.
- Hemoglobin (Hgb) >= 10.0 g/dL in the absence of transfusion within 14 days prior to screening laboratory assessment.
Platelets (Plt) count > 100,000 x 109/L.

- Estimated glomerular filtration rate (GFR) >= 51 ml/min based on Cockcroft-Gault equation or 24 hour urine collection.
- Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) < 2.5 x upper limit of normal (ULN) (< 5x ULN in patients with known liver metastases).

- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- The effects of AZD6738 and olaparib on the developing human fetus are unknown. For this reason and because ATR and PARP inhibitors as well as other therapeutic drugs used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use 2 highly effective forms of contraception prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
- Male patients who are sexually active must be willing to use barrier contraception for the duration of the study and for 1 week after the last study drug administration, with all sexual partners. Male patients must use a condom during treatment and for 6 months after the last dose of study drug(s) when having sexual intercourse with a pregnant woman or with a woman of childbearing potential. Female partners of male patients should also use a highly effective form of contraception for 6 months after the last dose of study drug(s) if they are of childbearing potential. True abstinence for either sex is an acceptable form of contraception and must be documented as such.
- Women of childbearing potential must have a negative serum or urine pregnancy test within 7 days prior to C1D1 treatment). Evidence of postmenopausal status or non-child bearing status must be documented. Postmenopausal is defined as:
- Aged more than 50 years and amenorrheic for at least 12 months following cessation of all exogenous hormonal treatments.
- Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy or bilateral salpingectomy but not tubal ligation, radiation-induced oophorectomy with last menses > 1 year ago, chemotherapy-induced menopause with > 1 year interval since last menses
- Amenorrhoeic for 12 months and serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and plasma oestradiol levels in the postmenopausal range for the institution for women under 50.
- Ability to understand a written informed consent document, and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations.
