CHENGDU, China, Aug. 17, 2026 /PRNewswire/ -- Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd. ("Kelun-Biotech" or the "Company", Stock Code: 6990.HK) announces its unaudited consolidated results for the period ended 30 June 2026 (the "Reporting Period").
Key information is as follows:
- Revenue amounted to approximately RMB 978 million, with sales of pharmaceutical products reaching RMB 657 million, up by 112% compared to the same period last year, driven by two factors: expert recognition of high quality clinical data and shift in treatment paradigms, and comprehensive enhancement of drug accessibility.
- The Company has established a comprehensive operational system in China encompassing R&D, manufacturing, quality management, and commercialization, with integrated drug development capabilities. The Company is also pursuing global expansion through international collaborations, leveraging external partnerships to accumulate global clinical development and commercialization experience, while exploring diversified pathways to progressively achieve independent overseas market entry.
- Focusing on ADC and novel DC, the Company not only has two ADC products that have been approved for marketing, but has also built a product pipeline that is differentiated and complimentary to approved ADCs in indications, efficacy performance and safety profile. Through the free combination of conjugation drug components, as well as the pairing with a diverse range of targeting conjugates including antibodies, small molecules, and peptides that leverage TAA/IO/ anti-angiogenetic-based mechanisms, the Company has proactively positioned innovative DC assets, including single-payload DCs such as radioisotope-based/ immuno-agonist-based/degrader-based, and dual-payload DCs such as cytotoxin + cytotoxin or immuno-agonist or degrader combinations, among others.
- Doubling down on ADC + IO therapies, including the combination of ADCs with PD-(L)1 or PD-1/VEGF agents, as well as the development of drug candidates with synergetic MoAs within one ADC compound.
- Beyond oncology, the Company has also expanded into important therapeutic areas such as autoimmune and metabolic diseases, and is currently conducting multiple clinical studies for asthma, chronic obstructive pulmonary disease (COPD), and atopic dermatitis.
Clinical development progresses efficiently, with a tiered expansion of the pipeline matrix
Focusing on high-incidence tumors such as lung cancer and breast cancer, the Company has built a well-layered clinical pipeline with significant synergistic potential, covering drug modalities including ADCs, immunotherapies, and small-molecule targeted therapies, while further expanding into major therapeutic areas such as autoimmune and metabolic diseases.
