MCP evidence snapshot: 5 August 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.

Why NCT07746141 is a hot trial to watch

Metastatic Solid Tumor is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07746141 is notable because it evaluates Tislelizumab in a Phase 1 design sponsored by BeOne Medicines Ltd.. The main development question is whether the protocol can translate its rationale into a clinically interpretable and operationally credible readout.

Trial landscape snapshot

Protocol design and endpoint interpretation

The purpose of this study is to test if the BG-85738 is safe and if it works in patients with advanced solid tumors with RAS mutations when it is given on its own and in combination.

Allocation is Non-Randomized, masking is None (Open Label), and the intervention model is Sequential Assignment. Planned enrollment of [object Object] participants across Not reported in the indexed record shapes statistical precision, execution risk and external validity. Interpretation should account for baseline risk, prior therapy, assessment schedule, missing-data handling and clinical relevance—not only statistical significance.

• Phase 1a (Part A and Part B): Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) (From first dose to 30 days after last dose or initiation of a new anticancer therapy, whichever occurs first, up to approximately 24 months) — An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporarily associated with the use of study treatment, whether considered related to study treatment or not. An SAE is any untoward medical occurrence that, at any dose, * Results in death * Is life-threatening * Requires hospitalization or prolongation of existing hospitalizat
• Phase 1a (Parts A and B): Number of Participants with Dose Limiting Toxicity (DLT) (Up to approximately 1 month)
• Phase 1a (Parts A and B): Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD) of BG-85738 as monotherapy or in combination with other antitumor agents (Up to approximately 1 month) — MTD is defined as the highest dose level with the target DLT closest but not exceeding 0.33. MAD is defined as the maximum administered dose and it is used when MTD is not reached.
• Phase 1a: Recommended Dose for Expansion (RDFE) of BG-85738 (Up to approximately 1 month)

Readout outlook and evidence gap

The current protocol points to [object Object] as the best available readout proxy. Because this is an active or newly posted study, a trial-specific result citation is not included until a normalized clinical-trial-result record becomes available. That gap is itself operationally important: teams should monitor first result indexing, conference abstracts, protocol amendments and changes to the primary-completion date.

Asset and sponsor context

Drug & Asset MCP profile: Tislelizumab is indexed as No normalized modality returned, with target No normalized target returned, mechanism No normalized mechanism returned, and global highest development status No normalized global status returned.

Company & Deal Intelligence MCP profile: BeOne Medicines Ltd. is resolved to a normalized organization record in MIDDLESEX COUNTY, United States. The organization workflow adds identity, location, portfolio and partnering context where available.

The sponsor profile matters because scientific rationale alone does not determine development value. Manufacturing readiness, portfolio fit, geographic reach, partnering capacity and the ability to fund confirmatory development can determine whether a positive signal becomes a competitive asset.

White space around this program

• Sharper patient selection: prospective biomarker or phenotype definitions that identify who is most likely to benefit.
• Clinically interpretable endpoints: outcomes connecting activity with function, symptoms, survival or treatment burden.
• Comparator relevance: evidence against the most decision-relevant contemporary standard of care.
• Broader external validity: evidence across additional geographies, demographic groups and real-world settings.
• Operational differentiation: a development path that closes the readout gap without sacrificing safety or durability.

What to monitor next

Monitor recruitment, enrollment changes, protocol amendments, endpoint hierarchy, primary-completion timing, first result indexing, asset ownership and sponsor partnerships. A change in endpoint, population or ownership can alter the probability of success before a headline data release.

Bottom line

NCT07746141 provides a focused lens on Metastatic Solid Tumor development. Its value will be determined by whether Tislelizumab can convert the current Phase 1 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
