CTR20260467 Difelikefalin acetate Chronic Kidney Disease-Associated Pruritus Clinical Landscape Report 2026: Design, Endpoints, Sponsor and Readout Outlook
Turn a newly registered trial into a decision-ready clinical landscape. This report examines CTR20260467 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: 27 August 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.
Why CTR20260467 is a hot trial to watch
Chronic Kidney Disease-Associated Pruritus is being segmented by mechanism, treatment setting, geography and endpoint architecture. CTR20260467 is notable because it evaluates Difelikefalin acetate in a Phase 2 design sponsored by Chengdu Guowei Biopharmaceutical 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 indexed record describes a Phase 2 study of Difelikefalin acetate in Chronic Kidney Disease-Associated Pruritus.
Allocation is 随机化, masking is 双盲, and the intervention model is 平行分组. Planned enrollment of 64 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.
- Primary endpoint (研究期间) — 药时曲线下面积（AUC0-t、AUC0-∞）、达峰时间（Tmax）、达峰浓度（Cmax），半衰期（t1/2），表观清除率（CL，CL/F），表观分布容积（Vz，Vz/F）等
- Primary endpoint (第4周) — 第4周时，受试者每日WI-NRS评分的周平均值相比于基线的变化。
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: Difelikefalin acetate 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: Chengdu Guowei Biopharmaceutical Co. Ltd. is resolved to a normalized organization record in Chengdu, 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
CTR20260467 provides a focused lens on Chronic Kidney Disease-Associated Pruritus development. Its value will be determined by whether Difelikefalin acetate can convert the current Phase 2 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
