Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - BGB-43395
Treatment: Drugs - Fulvestrant
Treatment: Drugs - Letrozole

Experimental: Dose Escalation - Phase 1a: Sequential cohorts of increasing dose levels of BGB-43395 will be evaluated as monotherapy and in combination with either fulvestrant or letrozole to assess for safety and tolerability.

Experimental: Dose Expansion - Phase 1b: The recommended dose for expansion (RFDE) for BGB-43395 (in combination with fulvestrant or letrozole) from Phase 1a will be evaluated in HR+ breast cancer and selected tumor-specific cohorts.


Treatment: Drugs: BGB-43395
Planned doses administered orally.

Treatment: Drugs: Fulvestrant
Standard dose administered via intramuscular injection.

Treatment: Drugs: Letrozole
Standard dose administered orally as a tablet.

Eligibility
Key inclusion criteria
* Phase 1a (Dose Escalation) and 1b (Dose Expansion): Participants with histologically or cytologically confirmed advanced, metastatic, or unresectable solid tumors associated with dependency on CDK4, including HR+ breast cancer, ovarian cancer, endometrial cancer, non-small cell lung cancer, and others.
* Phase 1a: Received prior therapy for their condition (if available) and should be refractory to or intolerant of standard-of-care therapies. In regions where approved and available, participants with HR+ breast cancer must have received at least 2 prior lines of treatment including endocrine therapy and a CDK4/6 inhibitor.
* Phase 1b: Selected tumor cohorts will include HR+/HER2- breast cancer and additional tumor types.
* Phase 1b: Participants with HR+/HER2- breast cancer enrolled in regions where CDK4/6 inhibitors are approved and available must have received at least one line of therapy for advanced disease including endocrine therapy and a CDK4/6 inhibitor. Participants can have received up to 2 lines of prior cytotoxic chemotherapy for advanced disease.
* Stable Eastern Cooperative Oncology Group (ECOG) Performance Status = 1.
* Female participants with metastatic HR+/HER2- breast cancer must be postmenopausal or receiving ovarian function suppression treatment.
* Adequate organ function without symptomatic visceral disease.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Prior therapy selectively targeting CDK4 (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 metastases.
* 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).
* Uncontrolled diabetes.
* Infection requiring systemic antibacterial, antifungal, or 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.
* Prior allogeneic stem cell transplantation, or organ transplantation.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
