MCP evidence snapshot: 24 July 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.
Why NCT07581795 is a hot trial to watch
Advanced HER2-Positive Breast Carcinoma is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07581795 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.

Protocol design and endpoint interpretation
This study is a randomized, open-label, controlled, multicenter Phase II trial conducted in patients with advanced HER2-positive breast cancer, aimed at evaluating the efficacy and safety of paclitaxel polymer micelles for injection combined with trastuzumab and adalimumab versus the paclitaxel-based regimen combined with trastuzumab as first-line treatment. Eligible subjects with histologically or cytologically confirmed advanced HER2-positive breast cancer were enrolled after obtaining informed consent. They were randomly assigned to two groups: the experimental group received paclitaxel polymer micelles for injection combined with trastuzumab, pertuzumab, and adrelumab; the control group received taxanes (paclitaxel, docetaxel, albumin-bound paclitaxel, paclitaxel polymer micelles) combined with trastuzumab and pertuzumab. Each treatment cycle lasted 3 weeks (Q3W), with administration on day 1 (D1) of each cycle. Therapy continued un
Allocation is Randomized, masking is None (Open Label), and the intervention model is Parallel 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） (From enrollment to the end of treatment up to approximately 24 months) — Objective Response Rate (ORR): Proportion of patients with best overall response of complete response (CR) or partial response (PR) according to RECIST 1.1 criteria.
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 Monoclonal antibody, with target HER2, mechanism HER2 antagonists, ADCC, and global highest development status Approved.
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
NCT07581795 provides a focused lens on Advanced HER2-Positive Breast Carcinoma 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.
