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 NCT07738757 is a hot trial to watch

MSI-H/dMMR Solid Tumors is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07738757 is notable because it evaluates Sacituzumab tirumotecan in a Phase 2 design sponsored by Peking Union Medical College 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, open-label, multicenter, single-arm Phase II study designed to evaluate the efficacy and safety of sacituzumab tirumotecan (sac-TMT/SKB264) in combination with tagitanlimab (KL-A167) as second-line or later therapy in patients with recurrent or metastatic MSI-H/dMMR gynecological malignancies, including endometrial cancer, ovarian cancer, and cervical cancer. The primary objective is to evaluate the objective response rate (ORR) per RECIST v1.1 as assessed by the investigator. Secondary objectives include evaluating overall survival (OS), progression-free survival (PFS) per RECIST v1.1, disease control rate (DCR), duration of response (DoR), and the safety and tolerability of the combination regimen.

Allocation is Non-Randomized, 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.

• Objective response rate(ORR) (up to 24 months) — Ãbjective Response Rate (ÃRR) is the percentage of participants who achieved a best overall response of Complete Response (CR) or Partial Response (PR). assessed byInvestigator based on RECiST version 1.1.

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: Sacituzumab tirumotecan 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: Peking Union Medical College Hospital is resolved to a normalized organization record in Beijing 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

NCT07738757 provides a focused lens on MSI-H/dMMR Solid Tumors development. Its value will be determined by whether Sacituzumab tirumotecan can convert the current Phase 2 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
