- 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

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.

with the exception of carcinoma in situ of the cervix, non-melanoma skin carcinoma,
low/intermediate risk localized prostate cancer (=< Gleason 7, =< T2N0M0, and
prostate-specific antigen (PSA) =< 20 ng/mL at diagnosis), ductal carcinoma in situ,
stage I uterine cancer, and non-muscle invasive urothelial carcinoma.

dose > 10 mg/day of prednisone (or equivalent).
