Additional inclusion criteria for participants in dose escalation (Part A2):

Additional inclusion criteria for participants in dose expansion (Part B1):
- Advanced or metastatic solid tumors that have undergone disease progression during treatment with a PARP inhibitor for an approved indication
- At least 1 measurable lesion assessable using standard techniques by RECIST v1.1 or PCWG-3 guidelines
- Non-irradiated, biopsiable tumor lesion
Additional inclusion criteria for participants in dose expansion (Part B2):
- Advanced or metastatic cancer that is refractory to standard therapies, or for which no standard therapies exist, or for which the investigator feels no other active therapy is required for the duration of the study with characteristics indicative of sensitivity to pol theta inhibition
- No prior treatment with a PARP inhibitor and must not have a disease for which there is an approved PARP inhibitor
- At least 1 measurable lesion assessable using standard techniques by RECIST v1.1 or PCWG-3 guidelines
Additional inclusion criteria for participants in dose expansion (Part B3):
- HER2-negative locally advanced or metastatic breast cancer
- Deleterious or suspected deleterious germline BRCA1 or BRCA2 mutation
- No more than 3 prior chemotherapy-inclusive regimens (including antibody conjugates)
- Prior treatment with a taxane or anthracycline unless contraindicated
- No prior treatment with a PARP inhibitor
- At least 1 measurable lesion assessable using standard techniques by RECIST v1.1
Additional inclusion criteria for participants in dose escalation (Part A3):
• Advanced or metastatic cancer for which a PARP inhibitor is an appropriate treatment option. Prior treatment with PARP inhibitor
General Exclusion Criteria:
- Women who are pregnant, breast feeding, or who plan to become pregnant while in the study or within 4 weeks after the last administration of ART4215; within 7 months after the last administration of talazoparib or within 6 months after the last administration of niraparib
- Men who plan to father a child while in the study or within 16 weeks after the last administration of ART4215 (Part A1/B1/B2); within 7 month after the last administration of study treatment with ART4215 in combination with talazoparib (Part A2/B3) or within 6 months in combination with niraparib (Part A3)
- Serious concomitant systemic disorder that would compromise the participants ability to adhere to the protocol including: opportunistic HIV/AIDs-related infection(s) within the past 12 months, hepatitis B virus, or hepatitis C virus; known history of clinical diagnosis of tuberculosis; malignancy prior to the one currently being treated [including myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML)] that is not in remission
- Have MDS/AML or features suggestive of MDS/AML
- Ongoing interstitial lung disease or pneumonitis
- Moderate or severe cardiovascular disease
- Symptomatic or uncontrolled brain metastases, spinal cord compression, or leptomeningeal disease requiring concurrent treatment; stable brain metastases are eligible
- Received a live vaccine within 30 days before the first dose of study treatment
- History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the patient's participation for the full duration of the study, or is not in the best interest of the patient to participate
- Recent major surgery within 4 weeks prior to entry into the study or minor surgery within 1 week of entry into the study
- Significant bleeding disorder or vasculitis or had a Grade ≥3 bleeding episode within 12 weeks prior to enrollment
- Currently enrolled in a clinical trial involving an investigational product or any other type of medical research judged not to be scientifically or medically compatible with this study
Additional exclusion criteria for participants in dose expansion (Part B3):
- First-line locally advanced and/or metastatic breast cancer with no prior adjuvant chemotherapy
- Inflammatory breast cancer
Additional exclusion criteria for participants in dose escalation (Part A3):
• Hypersensitivity to any of the components of niraparib

Part A1 will evaluate ART4215 monotherapy administered in 21 day cycles. Up to 90 participants will participate in this dose escalation arm.
Part A2 will evaluate ART4215 given in combination with talazoparib in 21 day cycles. Up to 40 participants will participate in this dose escalation arm.
In Part B1 dose expansion, up to 30 participants with solid cancers that have been treated with a PARP inhibitor for an approved indication will receive ART4215.
In Part B2 dose expansion, up to 20 participants with solid cancers with characteristics indicative of sensitivity to pol theta inhibition will receive ART4215.
In Part B3, approximately 120 participants with HER2 negative BRCA breast cancers will be randomized 1:1 to either ART4215 in combination with talazoparib or talazoparib alone.
Part A3 will evaluate ART4215 given in combination with niraparib in 21-day cycles. Up to 30 participants will participate in this dose escalation arm.
