August 25, 2021, Hong Kong --- Chinese leading biopharmaceutical company 3SBio（01530.HK) today unveiled its 2021 interim results. 3SBio maintained strong performance in core businesses, with core products occupying a leading market share. Meanwhile, the Company continuously increased investments in research and development, while significantly accelerating its pipeline. In the future, 3SBio will reinforce its position as an industry leader by enhancing its competitive edges with further integration of R&D, manufacturing, commercialization and investment cooperation.

Core businesses maintain strong growth and lead the industry 

In first half of 2021, 3SBio posted revenue of approximately RMB 3.11 billion, an increase of 15.3% over the same period last year. Gross profit rose 16.7% year on year to approximately RMB 2.59 billion. Net profit attributable to owners of the parent added 28% on a yearly basis to approximately RMB 900 million. R&D investment increased 35.6% on an annual basis to RMB 340 million.

3SBio’s multiple core products maintained strong momentum and consolidated their positions as market leaders. In the first half of 2021, TPIAO, which is used to treat thrombocytopenia, posted sales of RMB 1.521 billion, an increase of 10.7% year on year, and its market share was 72.3%. Sales of two recombinant human erythropoietin (“rhEPO”) products, EPIAO and SEPO, hit RMB 543 million, marking a year-on-year increase of 17.6%, and a market share of 42.8%. Yisaipu, a product to treat rheumatoid arthritis, ankylosing spondylitis, and psoriasis, had sales of RMB 429 million, a significant rise of 29.5% year on year. Inetetamab was included in the Chinese Society of Clinical Oncology (CSCO) Guidelines for the Diagnosis and Treatment of Breast Cancer (2021), becoming a cornerstone drug for the whole-process anti-HER2 treatment of patients with advanced breast cancer.

In the first half of 2021, sales of hair growth products led by Mandi doubled year on year. Among them, sales of Mandi (minoxidil tincture) reached RMB 258 million, a year-on-year increase of 100.3%. According to CPA data, Mandi had a share of 71.5% in its category, making itself an absolute market leader. Mandi is now available in more than 2,000 medical institutions, approximately 40,000 retail pharmacies, and e-commerce platforms including Tmall and JD.com, while a strategic partnership has been reached with chain operator Yonghe Hair Transplant. According to the Guidelines for the Diagnosis and Treatment of Androgenetic Alopecia in Chinese Population issued by the Chinese Medical Doctor Association), minoxidil is superior to other types of therapeutic drugs in preventing and improving androgenic alopecia (AGA) in terms of both efficacy and safety, with the highest-level recommendation. There are 250 million people with hair loss in China, and the current market penetration rate of Mandi is only 1-2%. With increasing demand for the treatment of hair loss, Mandi, as a leading OTC drug for external use to improve hair growth, has huge growth potential.

In addition, products in-licensed by 3SBio through partnerships will soon contribute to potential revenue growth. The Phase III clinical bridging trial of Remitch (nalfuraphine hydrochloride orally disintegrating tablets) under the cooperation between 3SBio and Toray, has been successfully completed, and it is expected to become the only product for the treatment of pruritus in patients on maintenance hemodialysis after it goes on the market. Based on the Company’s strong capabilities in sales channels in the nephrology field, the product is expected to benefit millions of Chinese patients.

Apart from strong momentum in core products, 3SBio’s contract development and manufacturing organization (CDMO) business has also seen significant progress in the first half of 2021. Revenue from 3SBio’s CDMO business, consisting of subsidiaries such as Shenyang Desheng, Sunshine Guojian and Italy-based Sirton, posted a year-on-year rise of 9.4% to RMB 40.05 million. Among them, the Shenyang Desheng project has a total planned area of 500 mus, with an aim to build a domestically leading site for biopharma CDMO, biopharma raw and auxiliary supplies and consumables manufacturing and biopharma core process equipment. The site will meet the GMP standards in China, the EU and the United States, and serve global markets. The Phase I CDMO project at Shenyang Desheng, covering an area of more than 110 mus, is planned to have annual capacities of 199,000 liters of original solutions and 1 billion doses of injections. Initially, the production capacity of 76,000 liters will be put into operation in 2022.

Accelerating the pipeline development

In terms of R&D, 3SBio has been accelerating its pipeline via in-house projects and external partnerships. In the first half of 2021, 3SBio had a total of 35 product candidates under its pipeline, of which 24 were developed as innovative drugs in China. The candidates included 21 monoclonal antibodies or bispecific antibodies, 5 other biological products, and 9 small molecule drugs.
