MCP evidence snapshot: 20 July 2026; publication date: 20 July 2026. Trial records can change after the snapshot and should be rechecked before operational decisions.

Why CTR20262483 is a hot trial to watch

Hormone receptor positive HER2 positive breast cancer is increasingly segmented by mechanism, biomarker, treatment setting, geography and endpoint architecture. CTR20262483 is notable because it evaluates Trastuzumab Brengitecan in a Phase 2 design while BICR基于RECISTv1.1评估的无进展生存期（PFS） serves as the main decision variable. The critical question is whether the protocol can convert its rationale into a clinically interpretable and operationally credible readout.

PatSnap Clinical Trials MCP makes protocol fields machine-readable, while the companion asset and organization servers add development-status, target and sponsor context.

Trial landscape snapshot

Design and endpoint interpretation

The phase label is only the starting point. Allocation is 随机化, masking is 开放, and the intervention model is 平行分组. Planned enrollment of 120 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: BICR基于RECISTv1.1评估的无进展生存期（PFS） (整个试验期间)
• Secondary: 总生存期（OS） (整个试验期间)
• Secondary: 研究者基于RECISTv1.1评估的无进展生存期（PFS） (整个试验期间)
• Secondary: BICR与研究者基于RECISTv1.1评估的客观缓解率（ORR）、缓解持续时间（DoR）、临床获益率（CBR）和疾病控制率（DCR） (整个试验期间)
• Secondary: 治疗过程中不良事件（TEAE）、治疗相关不良事件（TRAE）的发生类型、频率、严重程度 (筛选期至安全性访视)

• Netupitant/Palonosetron Hydrochloride and Dexamethasone With or Without Prochlorperazine or Olanzapine in Improving Chemotherapy-Induced Nausea and Vomiting in Patients With Breast Cancer (Phase 3): Cycle 1(Mean) = 4.51 units on a scale (Standard Error, 0.155); Cycle 1(Mean) = 4.93 units on a scale (Standard Error, 0.141)
• A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study of RDX-002 on Postprandial Triglycerides in Patients Discontinuing the Glucagon-like Peptide-1 (GLP-1) Agonists, Semaglutide, or Tirzepatide for the Treatment of Obesity (Phase 2): Incremental Postprandial Triglycerides (TG)(Mean) = 43.81 percent change (Standard Deviation, 92.373); Incremental Postprandial Triglycerides (TG)(Mean) = -51.91 percent change (Standard Deviation, 72.293)
• A Phase II Study to Evaluate the Delay in Ovulation Following Oral Levonorgestrel Plus Meloxicam Compared to Placebo in Obese But Normal Menstruating Women (Phase 2): Interval From First Dose to Evidence of Ovulation.(Mean) = 2.67 Number of days (Standard Deviation, 1.53); Interval From First Dose to Evidence of Ovulation.(Mean) = 4.0 Number of days (Standard Deviation, 0)

These indexed results are contextual benchmarks, not direct head-to-head evidence. Population, treatment line, endpoint definitions, follow-up and analysis sets may differ. Their value is to clarify the type and magnitude of evidence already visible in the competitive landscape.

Asset and sponsor context

Drug & Asset context: Trastuzumab Brengitecan (Phase 3; HER2 x Top I)

Company & Deal Intelligence context: Sichuan Baili Pharmaceuticals Co.,Ltd — China — http://www.baili-pharm.com; Baili Bio Chengdu Pharmaceutical Co. Ltd. — China

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 decide 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.
• Sequencing evidence: comparative data after the most 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 probability of success before a headline data release.

Bottom line

CTR20262483 is a focused lens on Hormone receptor positive HER2 positive breast cancer development. Its value will be determined by whether Trastuzumab Brengitecan can convert the current design into evidence that is clinically meaningful, operationally credible and differentiated from indexed benchmark readouts.
