Eligibility
Key inclusion criteria
General

* Female participants with advanced or metastatic HR+/HER2- breast cancer will be required to have ovarian function suppression using gonadotropin hormone-releasing hormone (GnRH) agonists (such as goserelin) or be postmenopausal.
* Eastern Cooperative Oncology Group (ECOG) Performance Status = 1.
* Adequate organ function.

Part 1 (Dose Escalation)

* Participants with histologically or cytologically confirmed advanced or metastatic solid tumors potentially associated with CDK2 dependency including HR+/HER2- breast cancer, platinum refractory or resistant serous ovarian, fallopian tube, primary peritoneal cancer (PROC), small cell lung cancer (SCLC), and others.
* Participants should have received prior available systemic therapy for their condition and should be refractory to or intolerant of standard-of-care therapies.
* Participants with advanced solid tumors must have measurable disease per RECIST 1.1.

Part 1 (Safety Expansion)

* Participants with advanced or metastatic HR+/HER2- breast cancer, PROC, or SCLC.

Part 2 (Dose Expansion)

Key exclusion criteria
* Prior therapy selectively targeting CDK2 inhibition. Prior CDK4/6 inhibitor therapy is permitted and required in local regions where it is approved and available.
* Known leptomeningeal disease or uncontrolled, untreated brain metastasis. Participants with a history of treated central nervous system (CNS) metastases may be eligible if they meet additional criteria.
* Any malignancy = 3 years before the first dose of study treatment(s) except for the specific cancer under investigation in this study and any locally recurring cancer that has been treated with curative intent (eg, resected basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the cervix or breast).

* Infection requiring systemic antibacterial, antifungal, or antiviral therapy antiviral therapy = 28 days before the first dose of study drug(s), or symptomatic COVID-19 infection.
* History of hepatitis B or active hepatitis C infection.
* Any major surgical procedure = 28 days before the first dose of study treatment(s).
