    Number of participants with AEs including serious adverse events (SAEs), defined as any unfavorable and unintended sign (including abnormal laboratory findings), symptom, or disease temporally associated with the use of study drugs, whether considered related to study drugs or not as graded by the National Cancer Institute-Common Terminology Criteria for Adverse Events [NCI CTCAE) V5.0/American Society for Transplantation and Cellular Therapy (ASTCT) for cytokine release syndrome [CRS] and immune effector cell associated neurotoxicity syndrome [ICANS])

Individual data sharing
Yes: BeOne 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. BeOne 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 BeOne review. Research teams must include a biostatistician and sign a Data Sharing Agreement prior to receiving access to clinical trial data.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BGB-R046 and Tislelizumab in people with Solid Tumor, run by BeOne Medicines at 8 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 11 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: This decision is due to a company business decision with a strategy change on the BGB-R046 development in Advanced or Metastatic Solid Tumors.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1a: Number of Participant with Adverse Events, Serious Adverse Events, Adverse Events of Clinical Interest and Dose-limiting Toxicities (time frame: Up to approximately 2 years). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 May 2026.
