SinoMab Dosed First Healthy Subject in Phase I Clinical Trial of SM17 in the U.S.

SinoMab BioScience Limited (“SinoMab” or the “Company”, together with its subsidiaries, the “Group”, stock code: 3681.HK), a Hong Kong-based biopharmaceutical company dedicated to the research, development, manufacturing and commercialization of therapeutics for the treatment of immunological diseases, today announced that, the first healthy subject has been dosed in the Phase I clinical trial of SM17 in the U.S. SM17 is a First-in-Class (FIC) humanized anti-IL-17RB monoclonal antibody. The subject is currently in a normal condition.

SM17 is the world’s first humanized IgG4-k monoclonal antibody targeting IL-17RB. SM17 is currently under development by SinoMab, and was engineered by LifeArc (a leading medical research charity based in the United Kingdom). SM17 was originally developed by Dr. Andrew McKenzie, FRS, who also serves as a member of the Company’s Scientific Advisory Board, at the MRC Laboratory of Molecular Biology (LMB).

SM17 could suppress Th2 immune responses by binding to IL-17RB on Type 2 Innate Lymphoid cells (ILC2s), blocking a cascade of responses induced by interleukin-25 (IL-25). IL-25 is a critical cytokine classified as “alarmin”, which has shown to be implicated in the pathogenesis of airway viral responses and allergic diseases, such as uncontrolled severe asthma. Uncontrolled severe asthma is associated with increased mortality/ morbidity, diminished quality of life and increased health expenditures. These patients are at a risk of recurrent asthma exacerbations and hospitalizations. The Company expected that targeting upstream mediators of the Th2 inflammatory cascade, such as IL-17RB on ILC2s, will have a broad effect on airway inflammation. The Company believes the huge potential of SM17 could satisfy unmet medical needs in asthma treatment. The Phase I study is a Single Ascending Dose (SAD) and Multiple Ascending Doses (MAD) to investigate the safety, tolerability and pharmacokinetics of SM17 in healthy subjects.

SM17 received Investigational New Drug (IND) approval from U.S. Food and Drug Administration (FDA) on 11 March 2022. Despite the pandemic, SinoMab have soon initiated the first-in-human dose in the Phase I clinical trial. This marks a significant milestone on the collaboration between SinoMab and LifeArc, and demonstrates the efficient implementation of SinoMab’s new drug R&D programs.

Melanie Lee, Chief Executive Officer of LifeArc, said: “We applied our antibody capabilities when working with Dr. Andrew McKenzie at the LMB, to firstly generate and select a clinical candidate antibody targeting IL-17RB, and then humanise it. After evaluating and choosing the lead candidate, it was licensed to SinoMab to take forward into clinical development and towards patients. It’s so rewarding to know that this antibody is going into trials and could eventually make a difference to people with severe asthma.”

Dr. Shui On LEUNG, Chairman, Executive Director and Chief Executive Officer of SinoMab said that: “SM17’s successful first-in-human dosing in Phase I clinical trial marked another milestone in our pipeline development. Following our flagship product, SM03 and key product, SN1011, we now have another key asset entering the clinical trial stage. This further assures our potential commercialization prospects and proves our capability for progressing multiple assets of R&D concurrently. We are confident of the enormous prospects for SM17’s clinical development as well as our commercialization opportunities in general. Moving forward, we will accelerate implementation of our projects, adhere to our vision of independent innovation to bring benefits to patients and create value for shareholders.”

SinoMab Announces IND APPLICATION FOR SN1011 ACCEPTED BY NMPA CDE

SinoMab BioScience Limited (“SinoMab” or the “Company”, together with its subsidiaries, the “Group”, stock code: 3681.HK), a Hong Kong-based biopharmaceutical company dedicated to the research, development, manufacturing and commercialization of therapeutics for the treatment of immunological diseases, is pleased to announce that, on 6 June 2022, an Investigational New Drug application (“IND”, for neuromyelitis optica spectrum disorder (“NMOSD”)) for SN1011 has been filed with and accepted by the Center for Drug Evaluation (the “CDE”) of the National Medical Products Administration of China (the “NMPA”). The Company plans to initiate the Phase II clinical study in China upon approval of the present IND. The present IND submission, once granted, will enable the Company to conduct clinical program in China for treatment of NMOSD.

SN1011 is the Company’s third generation, covalent reversible BTK inhibitor with improved safety, higher selectivity and superior efficacy and for the long-term treatment of systemic lupus erythematous, pemphigus vulgaris, multiple sclerosis, rheumatoid arthritis, and other immunological diseases. SN1011 differentiates from existing BTK inhibitors currently available in the market in terms of mechanism of action, affinity, selectivity and safety.

The Phase I clinical study (first-in-human clinical trial) of SN1011 was conducted in Australia and China in 2019 and completed in July 2021, which has demonstrated improved safety and good pharmacokinetics profile. Currently, the IND application for SN1011 in the treatment of systemic lupus erythematosus (SLE), pemphigus vulgaris (PV) and multiple sclerosis (MS) have been approved by NMPA, the Company plans to launch the Phase II clinical study of SN1011 for pemphigus in the third quarter of 2022. The Company is also planning an IND submission for multiple sclerosis (MS) in the U.S. in the second quarter of 2022, thereby accelerating the initiation of a global phase II trial in the third quarter of 2022.

NMOSD is an autoimmune-mediated inflammatory demyelinating disease of the central nervous system with predominant involvement of the optic nerve and spinal cord. The pathogenesis of NMOSD is mainly associated with aquaporin-4 (AQP4) antibodies and is a separate disease entity from multiple sclerosis, with severe optic neuritis and longitudinal extensive transverse myelitis as the main clinical features. However, the cause of NMOSD is unknown, with a combination of environmental factors such as smoking, low vitamin D levels, EBV infection and genetic susceptibility contributing to the development of the disease.

In 2020, according to inpatient registration data published in China, the incidence of NMOSD is about 0.278 (100,000 people/year), with children at 0.075 (100,000 people/year) and adults at 0.347 (100,000 people/year). NMOSD is seen at all ages, with young adults being the most common, with the average age of onset being 40 years. NMOSD is a highly recurrent and disabling disease, with 40-60% of patients experiencing a recurrence within one year and 90% within three years, and 50% of patients with a natural course of the disease having severe visual or motor impairment within 5-10 years. Currently, there are only three drugs officially approved by the US FDA or the European Union for the treatment of NMOSD, including complement inhibitors, IL-6 receptor blockers and B-lymphocyte-depleting agents. On 30 April 2021, the NMPA officially approved satralizumab for treatment of AQP4-IgG positive patients over the age of 12 years, making it the first drug approved for NMOSD treatment indications in mainland China. An IND application for NMOSD for SN1011 of SinoMab has been accepted by the CDE of the NMPA, and once approved, will facilitate the clinical research and development of new drugs for NMOSD in China.

Dr. Shui On LEUNG, Chairman, Executive Director and Chief Executive Officer of SinoMab said that: “NOMSD is the fourth indication of SN1011 in China following the approvals of IND application for systemic lupus erythematosus (SLE), pemphigus vulgaris (PV) and multiple sclerosis (MS), and is also the third IND application submitted by the Company to the regulatory authority this year, which fully reflects the team’s ability to simultaneously advance the research and development of multiple drug candidates and to effectively execute and communicate. The potential indications for SN1011 continue to expand, BTK inhibitor has a wide range of applications in the field of treatment of autoimmune diseases and huge future market potential. We believe that if the SN1011 product is successfully approved and commercialized in the future, it is expected to bring positive benefits to the Company, provide new options for the treatment of various autoimmune diseases and bring hope to the majority of patients.”
