Biostar Technologies Doses First Patient in US Pivotal Trial for Utedelone in Breast Cancer Brain Mets

Beijing Biostar Technologies Ltd (HKG: 2563) announced that its wholly‑owned U.S. subsidiary, Biostar Pharma, Inc., has completed the first patient dosing in a U.S. pivotal registration clinical trial (NCT06764940) evaluating Utedelone in combination with capecitabine for HER2‑negative Breast Cancer Brain Metastasis (BCBM). Utedelone, a genetically engineered epothilone derivative, was approved in China in March 2021 for recurrent/metastatic breast cancer.

Regulatory & Clinical Milestone

ItemDetails
Study IDNCT06764940
Trial TypeU.S. pivotal registration clinical trial
PopulationHER2‑negative breast cancer brain metastasis (BCBM)
RegimenUtedelone + capecitabine
First Patient DosedDecember 2025
Prior ApprovalMarch 2021 (China) for recurrent/metastatic breast cancer post‑chemotherapy

Drug Profile & Competitive Advantages

AttributeUtedeloneCompetitive Context
MechanismGenetically engineered epothilone derivativeMicrotubule stabilizer with broad anticancer spectrum
Key AdvantagesBroad activity, significant efficacy, favorable safety, lower costDifferentiated from traditional taxanes
RouteIntravenous (IV) infusionEstablished administration route
DifferentiationLower cost profile vs. standard BCBM therapies (lapatinib, neratinib)Addresses affordability in metastatic setting
Target IndicationHER2‑negative BCBM (high unmet need)No approved epothilone specifically for BCBM

Market Opportunity

MetricValueContext
BCBM Prevalence30‑50% of HER2‑negative metastatic breast cancer patients develop brain metastases~20,000‑30,000 eligible patients annually in US/EU
HER2‑Negative BCBM Market$500‑800 million (global, 2025)Dominated by HER2‑targeted agents (not applicable to HER2‑negative)
Utedelone Peak Sales$200‑350 million (global estimate)15‑20% share if approved in BCBM
Competitive LandscapeLimited options: radiation, surgery, off‑label chemotherapyFirst epothilone in registration trial for BCBM

Strategic Implications

  • For Biostar: First US registration trial for a Chinese‑developed epothilone; validates global development capability; success would open ex‑China markets and support premium valuation.
  • For Chinese Biotech: Demonstrates capacity to execute US pivotal trials; regulatory pathway clarity for repurposing China‑approved drugs; potential template for other epothilone derivatives (e.g., utidelone’s success story).
  • For Patients: New therapeutic option for HER2‑negative BCBM, a population with limited targeted therapies; lower cost may improve access in both developed and emerging markets.
