NCT07497386 Trastuzumab Rezetecan Locally Advanced Unresectable Breast Carcinoma Clinical Landscape Report 2026: Design, Endpoints, Sponsor and Readout Outlook
Turn a newly registered trial into a decision-ready clinical landscape. This report examines NCT07497386 using PatSnap Clinical Trials MCP for protocol design and endpoint evidence, with Drug & Asset MCP and Company & Deal Intelligence MCP used as the companion asset and sponsor enrichment workflow.

MCP evidence snapshot: 26 August 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.
Why NCT07497386 is a hot trial to watch
Locally Advanced Unresectable Breast Carcinoma is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07497386 is notable because it evaluates Trastuzumab Rezetecan in a Phase 2 design sponsored by Jiangsu Hengrui Pharmaceuticals Co., Ltd.. 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
The study is designed to compare the efficacy and safety of different dose groups of Trastuzumab Rezetecan or Trastuzumab Deruxtecan in patients with HR-positive, HER2-low unresectable locally recurrent/metastatic breast cancer. It will also exploratively evaluate the pharmacokinetic profile and immunogenicity of Trastuzumab Rezetecan.
Allocation is Randomized, masking is None (Open Label), and the intervention model is Parallel Assignment. Planned enrollment was not reported; study geography in 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).(Every 6 weeks after administration, approximately 14 months.)
Readout outlook and evidence gap
The current protocol points to not reported 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: Trastuzumab Rezetecan 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: Jiangsu Hengrui Pharmaceuticals Co., Ltd. is resolved to a normalized organization record in Lianyungang, 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
NCT07497386 provides a focused lens on Locally Advanced Unresectable Breast Carcinoma development. Its value will be determined by whether Trastuzumab Rezetecan can convert the current Phase 2 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
