NCT07551414 Zorifertinib Metastatic Malignant Neoplasm to the Leptomeninges Clinical Landscape Report 2026: Design, Endpoints, Sponsor and Readout Outlook
Turn a newly registered trial into a decision-ready clinical landscape. This report examines NCT07551414 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: 3 August 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.
Why NCT07551414 is a hot trial to watch
Metastatic Malignant Neoplasm to the Leptomeninges is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07551414 is notable because it evaluates Zorifertinib 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
A Prospective Study of Zorifertinib Combined with Intra-Ommaya Reservoir Cerebrospinal Fluid Chemotherapy for Leptomeningeal Progression in NSCLC Patients After Third-Generation EGFR-TKI Therapy
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.
- Response Assessment in Neuro - Oncology Leptomeningeal Metastases (RANO - LM) criteria (Until the end of the study (up to 3 years)) — RANO-LM uses a categorical classification (no single numeric score range) to define disease status: Complete Response (CR): All LM-related lesions disappear, no increase in ventricular size. Partial Response (PR): All measurable LM nodules shrink by ≥50% (sum of perpendicular diameters), no increase in ventricular size. Stable Disease (SD): Neither PR nor Progressive Disease (PD) criteria are met. Progressive Disease
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: Zorifertinib is indexed as Small molecule drug, with target EGFR L858R x EGFR-Ex19del, mechanism EGFR exon 19 deletion inhibitors, EGFR exon 21 L858R mutation inhibitors, and global highest development status Approved.
Company & Deal Intelligence MCP profile: Cancer Hospital Chinese Academy of Medical Sciences 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
NCT07551414 provides a focused lens on Metastatic Malignant Neoplasm to the Leptomeninges development. Its value will be determined by whether Zorifertinib can convert the current Phase 2 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
