发布时间:2026-08-28 来源:华泰证券
Biokin's 1H26 revenue grew by 9.4%YoY to RMB187mn,while attributable net profit(NP)/recurring net profit came in at RMB-1,637/-1,689mn(RMB-1,118/-1,176mn in 1H25),dented by rising R&D investments.In June/July 2026,iza-bren gained approvals for late-line nasopharyngeal carcinoma(NPC)and second-line(2L)esophageal squamous cell carcinoma(ESCC),marking astart of domestic commercialization.Biokin is moving towards global innovative drug operations.1)Iza-bren:We expect more indications to gain approvals and expand its domestic addressable market.Accelerating overseas registration and R&D,as well as accelerated expansion into first-line(1L)treatments and more indications,could continue unlocking its global value.2)T-Bren,BL-M14D1,and BL-M05D1 are entering late-stage clinical trials at home and abroad,shaping amore mature pipeline portfolio.Maintain BUY.
Iza-bren enters domestic commercialization
Biokin is running 16 domestic registration clinical trials for iza-bren.Currently,two indications have been approved(late-line NPC and 2L ESCC),one has its NDA accepted(2L+TNBC),and two recently met primary endpoints in interim analyses.We expect near-term catalysts for this product:1)phase-II data for 1L EGFRm NSCLC(in combination with osimertinib)could be updated at ESMO,and phase-III data for 2L EGFRm NSCLC and 3L+HR+/HER2-BC could be read out soon;2)NDAs for 2L EGFRm NSCLC and 3L+HR+/HER2-BC could be submitted within the year.We expect continuous indication approvals to further expand its domestic commercial potential.
Iza-bren:overseas clinical trials accelerated
Biokin has initiated four overseas registration trials for iza-bren,covering 1L TNBC,2L EGFRm NSCLC,2L+UC,and 1L EGFRm NSCLC.We expect to see more catalysts:1)global phase-I data for EGFRm NSCLC could be disclosed at WCLC,validating its overseas efficacy and safety;2)overseas clinical progress could trigger asecond milestone payment of USD250mn in 4Q26;3)the company is exploring iza-bren in combination with PD-L1/VEGF bispecific antibodies(bisAbs).We believe the IO bisAb+ADC combination could form ahighly competitive 1L regimen and cover more major indications.
T-Bren demonstrates BIC potential
1)T-Bren monotherapy demonstrates excellent efficacy and low ILD incidence in later-line treatments of HER2+BC,HER2-low BC,TNBC,and HER2+GC/GEJ,showing best-in-class(BIC)potential.Nine domestic registration trials targeting BC,GC,and NSCLC are under way.We expect the phase-III trial for 2L+HER2+BC to reach its primary endpoint in 2H26,followed by its first NDA submission.2)For BL-M14D1(DLL3 ADC),Biokin initiated aglobal phase-III trial for 1L ES-SCLC in 7M26.As the company's first self-initiated global phase-III trial,it further validates Biokin's global development capabilities.3)For BL-M05D1(Claudin18.2 ADC),a phase-III trial in China for GC/GEJ kicked off in 5M26,and we expect aglobal phase-III trial to commence going forward.4)Clinical trials for BL-M11D1(CD33 ADC)and GNC-038(tetra-specific antibody)are well on track.5)The company is accelerating the R&D of aseries of first-in-class(FIC)antibody-radionuclide conjugates(ARCs);phase-I trials for ARC001 and ARC002 are under way.
Earnings forecasts and valuation
