MCP evidence snapshot: 21 July 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.
Why NCT07689851 is a hot trial to watch
Recurrent Metastatic Gastric Carcinoma is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07689851 is notable because it evaluates Retlirafusp alfa in a Phase 2 design sponsored by Cancer Hospital Chinese Academy of Medical Sciences. The main development question is whether the protocol can translate its rationale into a clinically interpretable and operationally credible readout.

Protocol design and endpoint interpretation
Gastric Cancer is one of the leading causes of cancer-related death worldwide, and patients with unresectable locally advanced or metastatic disease have a poor prognosis. This study aims to evaluate the safety and efficacy of radiotherapy combined with CAPOX and SHR-1701, a PD-L1/TGF-β bispecific antibody, in patients with unresectable locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma. By improving local tumor control and enhancing systemic antitumor activity, this study seeks to increase the opportunity for curative-intent resection and improve survival outcomes in patients with advance gastric cancer.
Allocation is N/A, masking is None (Open Label), and the intervention model is Single Group Assignment. Planned enrollment of 60 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.
- Progression-Free Survival (PFS) (Up to 12 months) — Progression-free survival is defined as the time from initiation of study treatment to the first documented disease progression according to RECIST version 1.1 or death from any cause, whichever occurs first.
Readout outlook and evidence gap
The current protocol points to 2028-07-30 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
Trial-sourced asset: Retlirafusp alfa. The Drug & Asset MCP enrichment step is designed to add normalized targets, modality and global development status when an exact asset match is available.
Trial-sourced sponsor: Cancer Hospital Chinese Academy of Medical Sciences. Company & Deal Intelligence MCP is the companion workflow for resolving organization identity, corporate profile and partnering context.
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
NCT07689851 provides a focused lens on Recurrent Metastatic Gastric Carcinoma development. Its value will be determined by whether Retlirafusp alfa can convert the current Phase 2 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
