The research was terminated voluntarily due to changes in the company's business strategy regarding the development of BGB-24714, rather than any safety issues.

This study aims to understand how safe and well-tolerated a drug called BGB-24714 is when used alone, or in combination with chemotherapy or radiation therapy, for people with advanced or spreading solid tumors. The main objective is to identify the highest tolerable dose or the highest administered dose of BGB-24714. Additionally, the study aims to identify the most suitable doses for further investigation in larger groups of participants.

Key Eligibility Criteria :

1. Participants must sign a written informed consent form (ICF); and agree to comply with study requirement

2. Phase 1a (Dose Escalation):

   Part A, A-CN, and B: Participants with histologically or cytologically confirmed unresectable locally advanced or metastatic solid tumor previously treated with standard systemic therapy or for whom treatment is not available or not tolerated Note: Only Chinese participants will be eligible for Part A-CN.

   Part C: Participant has histologically or cytologically confirmed, locally advanced, unresectable Stage III Non-small cell lung cancer (NSCLC) suitable for definitive chemoradiotherapy (CRT)

   Part D: Participant with locally advanced, histologically confirmed inoperable esophageal squamous cell carcinoma (ESCC) suitable for definitive CRT

   Phase 1b (Dose Expansion): Participants with histologically or cytologically confirmed solid tumors of selected types previously treated with standard therapy.

3. Participants must be able to provide formalin-fixed paraffin embedded (FFPE) tumor tissue sample.

4. Phase 1a Part A, A-CN, B and Phase 1b: ≥ 1 measurable lesion per Response evaluation criteria in solid tumors (RECIST) v1.1

5. Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 1

Key Exclusion Criteria:

1. Active leptomeningeal disease or uncontrolled, untreated brain metastasis.
2. Any malignancy ≤ 3 years before the first dose of study drug(s) except for the specific cancer under investigation in this study and any locally recurring cancer that has been treated with curative intent
3. Any condition that required systemic treatment with either corticosteroids or other immunosuppressive medication ≤ 14 days before the first dose of study drug(s).
4. Clinically significant infection requiring systemic therapy ≤ 14 days before the first dose of study drug(s).
5. Prior exposure to agents with second mitochondria-derived activator of caspases (SMAC) mimetics, or other Inhibitors of apoptosis proteins (IAPs) antagonists.

NOTE: Other protocol defined inclusion/exclusion criteria may apply.

BeiGene shares data on completed studies responsibly and provides qualified scientific and medical researchers access to data and supporting documentation for clinical trials in dossiers for medicines and indications after submission and approval in the United States, China, and Europe. Clinical trials supporting subsequent local approvals, new indications, or combination products are eligible for sharing once corresponding regulatory approvals are achieved.

BeiGene shares data only when permitted by applicable data privacy and security laws and regulations, when it is feasible to do so without compromising the privacy of study participants, and other considerations.

Qualified researchers with appropriate competencies who are engaged in novel scientific research may submit a request for participant-level data with a research proposal for BeiGene review. Research teams must include a biostatistician and sign a Data Sharing Agreement prior to receiving access to clinical trial data.
