Summary

This study will evaluate the efficacy and safety of olaparib (MK-7339) monotherapy in
participants with multiple types of advanced cancer (unresectable and/or metastatic)
that: 1) have progressed or been intolerant to standard of care therapy; and 2) are
positive for homologous recombination repair mutation (HRRm) or homologous recombination
deficiency (HRD).

Eligibility

1. For all participants:
2. Has measurable disease per RECIST 1.1 or PCWG-modified RECIST 1.1 as assessed by the local site Investigator/radiology and confirmed by BICR.
3. Is able to provide a newly obtained core or excisional biopsy of a tumor lesion or either an archival formalin-fixed paraffin embedded (FFPE) tumor tissue block or slides.
4. Has a life expectancy of at least 3 months.
5. Has an Eastern Cooperative Oncology Group (ECOG) performance status of either 0 or 1, as assessed within 7 days of treatment initiation.
6. Male participants must agree to use contraception during the treatment period and for at least 95 days (3 months and 5 days) after the last dose of study treatment and refrain from donating sperm during this period.
7. A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies:
8. Is not a woman of childbearing potential (WOCBP).
9. Is a WOCBP and using a contraceptive method that is highly effective with low user dependency, or be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis), during the intervention period and for at least 180 days after the last dose of study intervention, AND agrees not to donate eggs (ova, oocytes) to others or freeze/store for her own use for the purpose of reproduction during this period. Abstains from breastfeeding during the study intervention period and for at least 30 days after the last dose of study intervention.
10. Has adequate organ function.
11. For participants who have non-breast or -ovarian cancers that are breast cancer susceptibility gene 1/2 (BRCA1/2) mutated (BRCAm), or who have cancers that are BRCA1/2 non-mutated and homologous recombination repair nonmutated:
12. Has a histologically- or cytologically-confirmed advanced (metastatic and/or unresectable) solid tumor (except ovarian cancer whose tumor has a germline or somatic BRCA mutation and breast cancer whose tumor has a germline BRCA mutation) that is not eligible for curative treatment and for which standard of care therapy has failed. Participants must have progressed on or be intolerant to standard of care therapies that are known to provide clinical benefit. There is no limit on the number of prior treatment regimens.
13. Has either centrally-confirmed known or suspected deleterious mutations in at least 1 of the genes involved in HRR or centrally-confirmed HRD.
14. For participants receiving prior platinum (cisplatin, carboplatin, or oxaliplatin either as monotherapy or in combination) for advanced (metastatic and/or unresectable) solid tumor, have no evidence of disease progression during the platinum chemotherapy or =4 weeks of completing the platinum-containing regimen.
15. For participants who have somatic BRCAm breast cancer:
16. Has histologically- or cytologically-confirmed breast cancer with evidence of metastatic disease.
17. Has a known or suspected deleterious mutation in breast cancer susceptibility gene (BRCA) 1 or BRCA2 and does not harbor a germline BRCA1 or BRCA2 mutation - testing can be done centrally or locally. Blood and tissue samples must be provided by all participants.
18. Has received treatment with an anthracycline unless contraindicated and a taxane in either the neoadjuvant/adjuvant or metastatic setting.
19. Participants with estrogen and/or progesterone receptor-positive disease must have received and progressed on at least one endocrine therapy (adjuvant or metastatic), or have disease that the treating physician believes to be inappropriate for endocrine therapy.
