发布时间:2026-05-06 来源:华泰证券
Biokin Pharmaceutical has reported 2025 revenue/attributable net profit/recurring net profit of RMB2,520/-1,054/-1,168mn(-56.7/-128.4/-132.1%YoY),with 1Q26 figures at RMB95/-775/-830mn(+40.3/-45.8/-48.9%YoY).The YoY declines in 2025 revenue/net profit reflected the high base effect from upfront licensing payments in 2024 and significantly higher R&D expenditure in 2025.We anticipate multiple catalysts in 2026:1)potential approval of two iza-bren indications within the year,marking the start of commercialization;2)continued enhancement of global competitiveness through Phase III data readouts and overseas registration trials for iza-bren;3)potential NDA submission for T-Bren in 2026,with steady progress in ADC,multi-specific antibody,and radiopharmaceutical pipelines.Maintain BUY.
Iza-bren’s domestic commercialization imminent
Iza-bren has initiated three overseas Phase II/III trials for TNBC 1L,NSCLC 2L,and UC 2L+.Domestically,16 registration trials have been launched,with NDAs for end-line nasopharyngeal carcinoma and second-line esophageal squamous cell carcinoma indications already accepted and granted priority review.Three Phase III trials have met primary endpoints.We anticipate several catalysts materializing over the next six months.Overseas:1)We expect 2-3 additional overseas Phase III trials to be initiated within the year,expanding into first-line treatment indications.2)The second USD250mn milestone payment is likely to be triggered by overseas clinical progress of iza-bren.Domestic:1)We expect two indications to gain approval this year,marking the start of commercialization.2)We anticipate multiple Phase III data readouts,including 2L+TNBC and 2L ESCC data at ASCO,followed by 2L EGFRm NSCLC and 3L+HR+/HER2-data at ESMO.3)We foresee the initiation of several domestic Phase III trials this year,further expanding the indication landscape.
T-Bren shows BIC potential with robust pipeline advancement
T-Bren monotherapy has shown superior efficacy in later-line HER2+BC,HER2-low BC,TNBC,and HER2+GC/GEJ,with low ILD incidence,underscoring its best-in-class(BIC)potential.Currently,nine pivotal registration trials targeting breast cancer,gastric cancer,and NSCLC are underway.We expect Phase III data for 2L HER2+BC in 2026,followed by the first NDA submission.The company’s pipeline continues to progress methodically:1)Claudin18.2 ADC has entered Phase III trials,while DLL3 ADC advances smoothly,with Phase III to gradually kick off on our estimates;2)GNC-038’s autoimmune Phase Itrial is ongoing,and we expect data disclosure by year-end;3)Rapid deployment of first-in-class(FIC)antibody-radionuclide conjugates(ARCs)includes ongoing Phase Itrials for ARC001 and ARC002.
Strong cash position supports R&D expansion
The company’s R&D expenditure reached RMB2.51bn in 2025 and RMB695mn in 1Q26(+74.2/40.4%YoY),driven by accelerated clinical development of core products including iza-bren.As of 1Q26,cash and cash equivalents stood at RMB2.93bn,reflecting arobust liquidity position.In 2026,we expect receipt of asecond USD250mn milestone payment to bolster the company's financial reserves.
Earnings forecasts and valuation
Given the company’s continued ramp-up in R&D investment,we raise our expense ratio projections.We now forecast 2026/2027/2028 attributable net profit of RMB-733/-1,915/-1,521mn(previous 2026/2027:RMB-10/-1,473mn).Given the validation of iza-bren’s superior efficacy and safety in core indications and the smooth progress of several Phase III clinical trials,we raise our assumption for success probability of iza-bren.Using the DCF method,we assign atarget price of RMB336.12(WACC 7.1%,perpetual growth rate 3.0%,previous target price:RMB314.67).
