MCP evidence snapshot: 3 August 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.

Why NCT07729033 is a hot trial to watch

Advanced biliary tract cancer is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07729033 is notable because it evaluates Envafolimab in a Phase 2 design sponsored by Tianjin Medical University Cancer Institute and Hospital. 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

This is a prospective, single-arm, Phase II study evaluating sacituzumab tirumotecan combined with envafolimab in patients with TROP2-positive advanced biliary tract cancers who have progressed on first-line immunochemotherapy. Up to 28 eligible patients will be enrolled.After screening, eligible patients receive sacituzumab tirumotecan (5 mg/kg IV, d1, Q2W) plus envafolimab (300 mg SC, d1, Q2W) for 3 cycles, with subsequent treatment at the investigator's discretion. Tumor imaging assessments per RECIST v1.1 are performed at Week 6, then every 6 weeks (up to 48 weeks) and every 12 weeks (thereafter) until disease progression, new therapy, loss to follow-up, or death. Post-treatment survival follow-up is conducted by phone every 3 months. The study includes a safety run-in (6 patients) followed by an expansion phase using Simon's two-stage design (first stage: 15 patients; second stage: total 28 patients). The safety run-in stops if >2

Allocation is N/A, masking is None (Open Label), and the intervention model is Single Group Assignment. Planned enrollment of [object Object] participants across China 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.

• ORR (1 year) — Objective response rate (ORR) of sacituzumab tirumotecan combined with envafolimab in TROP2-positive advanced biliary tract cancers previously treated with first-line immunotherapy combined with chemotherapy, as assessed by the investigator per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1).

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: Envafolimab is indexed as Nanobody, Antibody fusion proteins, with target PDL1, mechanism PDL1 inhibitors, and global highest development status Approved.

Company & Deal Intelligence MCP profile: Tianjin Medical University Cancer Institute and Hospital is resolved to a normalized organization record in Tianjin Shi, China. 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

NCT07729033 provides a focused lens on Advanced biliary tract cancer development. Its value will be determined by whether Envafolimab can convert the current Phase 2 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
