susceptibility gene 1/2 (BRCA1/2) mutated (BRCAm), or who have cancers that are
BRCA1/2 non-mutated and homologous recombination repair nonmutated:

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.

- Has either centrally-confirmed known or suspected deleterious mutations in at least 1
of the genes involved in HRR or centrally-confirmed HRD.

- For participants receiving prior platinum (cisplatin, carboplatin, or oxaliplatin

solid tumor, have no evidence of disease progression during the platinum chemotherapy
or =4 weeks of completing the platinum-containing regimen.

- For participants who have somatic BRCAm breast cancer:

- Has histologically- or cytologically-confirmed breast cancer with evidence of
metastatic disease.

- 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.

- Has received treatment with an anthracycline unless contraindicated and a taxane in
either the neoadjuvant/adjuvant or metastatic setting.

- 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

squamous cell carcinoma of the skin, ductal carcinoma in situ, or cervical carcinoma
in situ that has undergone potentially curative therapy are not excluded.

- Has myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) or with features
suggestive of MDS/AML.

- Has known central nervous system (CNS) metastases and/or carcinomatous meningitis.
Note: Participants with previously treated brain metastases may participate if
radiologically stable, clinically stable, and without requirement for steroid
treatment for at least 14 days prior to the first dose of study treatment.

- Has received colony-stimulating factors (e.g., granulocyte colony-stimulating factor
[G-CSF], granulocyte-macrophage colony-stimulating factor [GM-CSF] or recombinant
erythropoietin) within 28 days prior to the first dose of study treatment.

- Has a known history of human immunodeficiency virus (HIV) infection.

- Has known active hepatitis infection (i.e., Hepatitis B or C).

- Is unable to swallow orally administered medication or has a gastrointestinal disorder
affecting absorption (e.g., gastrectomy, partial bowel obstruction, malabsorption).

- Has received prior therapy with olaparib or with any other polyadenosine 5'
diphosphoribose (poly[ADP ribose]) polymerization (PARP) inhibitor.

- Has a known hypersensitivity to the components or excipients in olaparib.

- Has received previous allogenic bone-marrow transplant or double umbilical cord
transplantation (dUCBT).

- Has received a whole blood transfusion in the last 120 days prior to entry to the
study. Packed red blood cells and platelet transfusions are acceptable if not
performed within 28 days of the first dose of study treatment.

- Has received any anti-neoplastic systemic chemotherapy or biological therapy, targeted
therapy, or an anticancer hormonal therapy within 3 weeks prior to the first dose of
study intervention.

- Has a primary cancer of unknown origin.

- Has received prior radiotherapy within 2 weeks of start of study intervention.
Participants must have recovered from all radiation-related toxicities, not require
corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted
for palliative radiation (=2 weeks of radiotherapy) to non-CNS disease.
