Outcome Measures
Primary Outcomes (2)
Part A: Number of participants with Dose Limiting Toxicities (DLTs)
Severity of adverse events as assessed by the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) v5.0.
From first dose of study treatment until the end of Cycle 1 (each cycle is 21-days)
Part B2: Progression free survival (PFS)
PFS is defined as the time from randomization until objective disease progression as defined by Response evaluation criteria in solid tumors (RECIST) v1.1 or death by any cause in the absence of progression, regardless of whether the patient withdraws from study medication or receives another anti-cancer therapy prior to progression.
Until disease progression (Upto 3.7 years).
Secondary Outcomes (11)
Part B2: Number of participants with Adverse events
Screening (≤28 days) Until follow-up visit (90 days after discontinuation)] (up to 3.7 years)
Best overall response (BOR)
Screening (≤28 days) Until disease progression/recurrence (Upto 3.7 years)
Objective Response Rate (ORR)
Screening (≤28 days) Until disease progression/recurrence (Upto 3.7 years)
Disease control rate (DCR)
Screening (≤28 days) Until disease progression (Upto 3.7 years)
Duration of response (DOR)
Screening (≤28 days) Until disease progression (Upto 3.7 years)
- +6 more secondary outcomes
Study Arms (3)
Part A1 (ART6043 as monotherapy)
EXPERIMENTALPatients with advanced or metastatic cancer will receive ART6043 administered in 21-day cycles.
Part A2 (ART6043 in combination with olaparib)
EXPERIMENTALPatients with advanced or metastatic cancer and with PARPi as an appropriate treatment option will receive ART6043 in combination with olaparib twice daily (BID) in 21-day cycles.
Part B2 (ART6043 in combination with olaparib)
EXPERIMENTALPatients with gBRCA-m, HER2-ve locally advanced or metastatic breast cancer will be randomly assigned to receive ART6043 in combination with olaparib or olaparib alone.

Eligibility Criteria
You may qualify if:
- Patients who have discontinued all previous chemotherapeutic agents, non-hormonal targeted therapy, or investigational drugs for at least 21 days or 5 half-lives (not including palliative radiotherapy at focal sites), whichever is shorter. Endocrine and hormonal therapies for the treatment of cancer must have been discontinued (unless for the treatment of Prostate Cancer) at least 7 days before receiving study medication. Palliative radiotherapy must have completed prior to start of study treatment.
- Resolution of all toxicities of prior therapy or surgical procedures.
- Performance status of 0-2 on the Eastern Cooperative Oncology Group (ECOG) scale.
- Have adequate organ function.
- Patients of childbearing potential and patients with partners of childbearing potential are required to use highly effective contraception.
- Have an estimated life expectancy of ≥12 weeks, in the judgment of the investigator.
- Advanced or metastatic cancer. Tumors with genetic lesions known to cause loss of function of known DDR genes based on available pre-existing testing are encouraged.
- Advanced or metastatic cancer with genetic lesions known to cause loss of function of known DDR genes based on available, pre-existing testing.
- Patients for whom a PARPi is an appropriate treatment option. Patients may have received prior treatment with a PARPi.
- Histologically or cytologically confirmed HER2-ve locally advanced or metastatic carcinoma of the breast.
- Documentation of a deleterious or suspected deleterious gBRCA mutation.
- Previously treated with chemotherapy in the neoadjuvant, adjuvant or metastatic setting unless medically contraindicated.
- Prior treatment with a taxane in the neoadjuvant, adjuvant, locally advanced, or metastatic setting unless medically contraindicated.
- Patients must have received no or ≤1 month of prior treatment with a PARPi.
You may not qualify if:
- Patients who are pregnant.
- Patients with Myelodysplastic syndrome (MDS)/Acute myeloid leukemia (AML) or with features suggestive of MDS/AML.
- Have ongoing interstitial lung disease or pneumonitis.
- Have any major gastrointestinal issues that could impact absorption of ART6043 or olaparib.
- Patients with brain metastases (patients with treated brain metastases could be eligible if follow-up brain imaging after central nervous system-directed therapy shows no evidence of progression).
- Have received a live vaccine within 30 days before the first dose of study treatment.
- Recent major surgery within 4 weeks prior to entry into the study.
- Have a significant bleeding disorder or vasculitis or had a Grade ≥3 bleeding episode within 12 weeks prior to enrollment.
- Have a history of allergy or hypersensitivity to study drug components.
- First-line locally advanced and/or metastatic breast cancer with no prior adjuvant chemotherapy.
- Inflammatory breast cancer.
