Trimer-Tag™(Protein Trimerization)
Overview of Patent Technology Platform
Trimer-Tag is the only technology platform in the world that uses human-derived trimerization tags to design and develop secreted covalently linked recombinant trimeric fusion proteins. Trimeric proteins developed using the Trimer-Tag technology platform are highly effective and safe against trimer-dependent disease targets. This technology platform enables the trimerization of target proteins, thereby targeting a wide range of natural diseases that rely on protein trimerization and biological targets, offering broad research and development potential. This includes dozens of enveloped RNA viruses such as coronaviruses, rabies virus, respiratory syncytial virus, influenza virus, human immunodeficiency virus, and Ebola virus, as well as cytokines from the tumor necrosis factor superfamily. These tumor necrosis factor superfamily cytokines have multiple important biological functions and are associated with certain cancers and autoimmune diseases. Therefore, for a variety of viruses and TNFSF-related diseases, the Trimer-Tag technology platform has considerable market potential in global disease areas.
"S-trimer" recombinant protein
Overview of the COVID-19 Candidate Vaccine SCB-2019
One of the core products of Clover is the 'S-trimer' recombinant protein COVID-19 candidate vaccine SCB-2019. Unlike traditional inactivated virus vaccines, Clover mainly uses Trimer-Tag technology and genetic recombination methods to construct an expression vector for the 'S-trimer' recombinant protein vaccine gene. Through gene transfection, a covalent trimer fusion protein recombinant antigen 'S-trimer' that is highly conformationally similar to the natural surface antigen S protein of coronaviruses is expressed and purified in mammalian cells. The vaccine has achieved primary and secondary endpoints for protective efficacy in global pivotal Phase 2/3 clinical trials, with an overall protective efficacy of 67% against any severe illness caused by any strain. The Delta variant is currently the main prevalent strain globally, accounting for more than 90% of all COVID-19 cases worldwide. All observed COVID-19 strains in the analysis of this clinical trial results were variants, showing that the protective efficacy of the COVID-19 candidate vaccine SCB-2019 against COVID-19 caused by the Delta variant was 79%, against the Gamma variant was 92%, and against the Mu variant was 59%.
Relying on its unique technical barriers in vaccine research and development, Clover has taken the lead in achieving a qualitative breakthrough in solving the problem of global COVID-19 variants. At the same time, Clover is the first innovative biopharmaceutical company on the Chinese mainland to receive CEPI funding and cooperation. CEPI has agreed to provide up to $3.605 billion in funding to support the development of SCB-2019. SCB-2019 is expected to become one of the first recombinant protein COVID-19 vaccines to be commercially launched globally, with a promising commercial outlook.
Protein tripeptide
Overview of Antitumor Targeted Drug SCB-313
SCB-313, as one of the Clover clinical pipeline products, is an innovative recombinant human tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-trimer fusion protein used for the treatment of patients with malignant intracavitary tumors. Malignant intracavitary tumors include malignant ascites, malignant pleural effusion, and peritoneal cancer. These tumors have a large patient population, with an estimated global number of 3.03 million patients by 2030, and 760,000 in China. Malignant intracavitary tumors have always been considered a major clinical challenge by oncologists, severely affecting the quality of life and survival period of patients. Currently, there are no effective treatment methods in clinical practice, and there is a high unmet clinical need for many cancer patients worldwide.

Enbrel® (etanercept)
Overview of Biosimilar SCB-808
SCB-808 is a biosimilar of the pre-filled small-volume injection Enbrel®, used for the treatment of rheumatic diseases, including ankylosing spondylitis and rheumatoid arthritis. It is expected that by 2030, there will be 6.41 million people with rheumatoid arthritis and 4.05 million patients with ankylosing spondylitis in China. The treatment of ankylosing spondylitis and other rheumatic diseases remains an unmet medical need, with most patients still suffering from severe under-treatment. Clover Biologics has developed SCB-808 as a pre-filled small-volume injection that allows patients or their families to administer injections at home, filling the gap in the domestic market for enbrel aqueous injections.
