Participants must have received no more than 2 prior lines of endocrine therapy in the advanced or metastatic setting and no more than 1 prior line of chemotherapy or an antibody-drug conjugate in the advanced or metastatic setting.
Key Exclusion Criteria:
* Prior therapy with KAT6A/B inhibitor in any treatment setting.
* Participants with advanced/metastatic, symptomatic, visceral spread, that are at risk of life-threatening complications in the short term.
* Known active or symptomatic central nervous system (CNS) metastases, carcinomatous meningitis, leptomeningeal disease, or a spinal cord compression that require CNS-specific treatment, or participants who did not demonstrate clinical and radiologic stability during the last 2 months prior to the first dose of study treatment or require or are currently on steroid therapy for CNS metastases.
* History of cerebral vascular disease, including transient ischemic attack, within 6 months prior to the first dose of study treatment.
