MCP evidence snapshot: 7 August 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.

Why NCT07647016 is a hot trial to watch

Hormone receptor positive HER2 negative breast cancer is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07647016 is notable because it evaluates Trastuzumab in a Phase 2 design sponsored by Fudan University. 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 UNITY study is a prospective, single-arm, single-center, Phase II clinical trial conducted by Fudan University Shanghai Cancer Center. It aims to evaluate the efficacy and safety of Trastuzumab Deruxtecan (T-DXd) combined with ivonescimab in patients with hormone receptor-positive (HR+), HER2-negative recurrent or metastatic breast cancer. Approximately 53 patients will be enrolled. Eligible participants must have histologically confirmed advanced HR-positive breast cancer with HER2-low or HER2-ultralow expression. They must have experienced recurrence, metastasis, or disease progression after prior treatment with a CDK4/6 inhibitor (including in the adjuvant setting) and have received at most one line of systemic chemotherapy for advanced disease. The study permits the enrollment of patients with central nervous system (CNS) metastases. The primary endpoint is the Overall Response Rate (ORR). Key secondary endpoints include Clinica

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 (From treatment initiation until disease progression or death, assessed by RECIST v1.1., assessed up to 24 months) — ORR is the percentage of evaluable patients with a confirmed investigator-assessed response of CR (complete response) or PR (partial response) per RECIST v1.1 .Time from randomization to disease progression or death, assessed by 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: Trastuzumab 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: Fudan University is resolved to a normalized organization record in Shanghai 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

NCT07647016 provides a focused lens on Hormone receptor positive HER2 negative breast cancer development. Its value will be determined by whether Trastuzumab can convert the current Phase 2 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
