Uni-Bio Science Group and Kexing Biopharm Forge Strategic Partnership to

Accelerate Global Expansion of Osteoporosis Treatment Bogutai®

Zhangqiu District, Jinan City, Shandong Province – September 2025

Uni-Bio  Science  Group  (“the  Group”)  is  pleased  to  announce  the  signing  of  a  strategic cooperation   agreement   with   Kexing   Biopharm   (Stock   Code:   688136.SH), a leading biopharmaceutical company with extensive expertise in global commercialization. Under this landmark  agreement,  Beijing  Genetech  Pharmaceutical  Co.,  Ltd.  (“Beijing  Genetech”),  a subsidiary of the Group, has granted Kexing Biopharm exclusive rights to commercialize Bogutai®  (Teriparatide Injection) in six international markets, including Saudi Arabia, Egypt, Morocco, Colombia, Argentina, and Mexico (“Cooperation Regions”). Bogutai®  is expected to complete registration and generate revenue in the Cooperation Regions as early as the end of 2026. The signing ceremony, held in Zhangqiu District, Jinan City, marks a pivotal step in the Group’s international expansion and its commitment to advancing osteoporosis care worldwide.

Pioneering Osteoporosis Treatment with Proven Results

Bogutai®   is  a  recombinant  human  parathyroid  hormone  analog  (PTH1–34),  an  anabolic treatment  for  osteoporosis  that  has  been  widely  recognized  for  its  efficacy  and  safety. Recommended by numerous domestic and international clinical guidelines, Teriparatide is particularly  effective  in  improving  bone  microarchitecture  and  reducing  fracture  risk  in postmenopausal women at high risk of fractures.

Since its launch in China in March 2024, Bogutai®  has demonstrated rapid market adoption, achieving a remarkable revenue growth of 248.9% year-on-year in the first half of 2025, reaching approximately HK$65.6 million. This impressive performance underscores the strong demand for innovative osteoporosis therapies and highlights the untapped potential of Bogutai® in global markets.

Addressing the Global Osteoporosis Epidemic

Osteoporosis, often referred to as a “silent killer,” affects over 200 million people globally, with the  aging  population   exacerbating  its  prevalence.   Early-stage  osteoporosis  is  typically asymptomatic, leading to delayed diagnoses and severe complications such as fractures. In China, for example, only 6.5% of individuals receive osteoporosis treatment within six months of a fracture. Similarly, emerging markets across the Middle East and North Africa face low diagnosis and treatment rates despite growing awareness and significant patient populations.

Injectable therapies like Teriparatide have been recommended by the Guidelines for Rational Drug  Use  of  Osteoporosis  in  Primary  Care  (2021)  for  patients  unable  to  tolerate  oral medications, those with poor adherence, or individuals at high risk of fractures, including elderly patients with multiple vertebral or hip fractures. With its targeted mechanism of action as a bone-forming agent, Bogutai®  is uniquely positioned to address this unmet medical need in both established and emerging markets. It is estimated that the osteoporosis market in the Cooperation Regions is nearly USD 1.5 billion, with a patient population exceeding 10 million.

A Collaboration Built on Complementary Strengths

Commenting on the partnership, Mr. Kingsley Leung, Chairman of Uni-Bio Science Group, said: “Teriparatide Injection is a transformative therapy with immense potential in overseas markets.  By partnering  with  Kexing  Biopharm,  a  company  with  a  robust  international commercialization network and proven operational expertise, we are confident in our ability to bring Bogutai®  to patients in need across key regions. This collaboration represents a critical step in our mission to improve global bone health. ”

Mr. Zhao Yanqing, General Manager ofKexing Biopharm, added: “We are excited to join forces with Uni-Bio Science Group to unlock the regional potential of Bogutai® . With our established capabilities in regulatory approvals and market promotion,  we aim to accelerate product registration and commercialization, ensuring that this innovative therapy reaches patients quickly and effectively. ”

Enhancing Global Competitiveness in Osteoporosis Care

With over 20 years of international commercialization experience, Kexing Biopharm has built a strong marketing network spanning the European Union and emerging markets. The addition of Bogutai® to its portfolio complements its existing success  with  previously  introduced denosumab injection, creating a comprehensive suite of osteoporosis treatments that combines “anti-resorptive” and “bone-forming” therapies. This synergy enhances the competitiveness of both companies in addressing the growing global demand for osteoporosis care.

For Uni-Bio  Science Group, this partnership is a key milestone in its internationalization strategy. Bogutai®  is expected to generate revenue in the Cooperation Regions as early as the end of 2026, and with its competitive pricing, it may achieve higher profit margins. Beyond the collaboration  with  Kexing  Biopharm,  the  Group  is  actively  pursuing  FDA  approval  for Bogutai®  in the United States, having already received a waiver for in vivo bioequivalence studies. With this expedited regulatory pathway, FDA approval is anticipated in 2027, further solidifying the Group’s position as a leader in osteoporosis treatment.

The Group is also advancing innovative pipeline products, including Uni-PTH (microneedle) for osteoporosis and UB107 (a Class III medical device) for bone repair, reinforcing its commitment to addressing unmet medical needs in bone metabolism and regenerative medicine.

Shaping the Future of Osteoporosis Treatment

Looking ahead, Uni-Bio Science Group remains dedicated to expanding its global footprint, deepening strategic partnerships, and accelerating the development of innovative therapies. By bringing Chinese innovation to the world, the Group aims to improve the lives of osteoporosis patients and set new standards in bone health and regenerative medicine.

About Bogutai®  (Teriparatide Injection)

Bogutai®  (Teriparatide Injection) is a biologically expressed recombinant human parathyroid hormone analog (PTH1–34), representing the active 34-amino-acid N-terminal region of the full 84-amino-acid human parathyroid hormone. This advanced therapeutic agent is specifically indicated for postmenopausal women with osteoporosis who are at high risk of fractures.

Bogutai®  exerts its effects by stimulating osteoblast activity, promoting new bone formation, and increasing bone mineral density (BMD). Unlike antiresorptive therapies that primarily inhibit bone resorption, Bogutai®  actively enhances bone remodeling by increasing osteoblast- mediated bone deposition while indirectly regulating osteoclast activity to maintain a balanced bone turnover. This anabolic mechanism makes it a highly effective treatment option for reducing the risk of fractures and improving  skeletal integrity in patients with severe osteoporosis.
