Clover Biopharmaceuticals, a global clinical-stage biotechnology company focused on discovering and developing transformative biologic therapies and vaccines, today announced the formation of its Scientific Advisory Board (SAB) comprised of internationally-renowned experts in the vaccine industry, public health and policy making. The SAB will provide strategic oversight and guidance to the global development of Clover’s protein-based COVID-19 S-Trimer vaccine programs.
Joshua Liang, Chief Executive Officer of Clover Biopharmaceuticals, commented: “We are honored to welcome these leading vaccine experts to our newly-formed SAB. The SAB will provide a valued source of counsel as we continue to rapidly develop our COVID-19 S-Trimer vaccine. With a broad range of backgrounds, the SAB will serve a valuable role in advising Clover in all aspects of our global vaccine development and access in the critical months to come.”
Ralf Clemens, M.D., Ph.D., Chairman of the SAB, added: “I am pleased to lead this team of leaders in vaccine and immunization with diverse and complementary expertise and decades of experience to support Clover in the innovative work that they are doing with the COVID-19 S-Trimer vaccine utilizing their proprietary Trimer-Tag© technology. All of the SAB members share in Clover’s vision of developing and producing a safe, effective and accessible vaccine that can provide much needed relief to communities around the world to contain this pandemic.”
Clover’s COVID-19 S-Trimer vaccine was developed by combining the trimeric SARS-CoV-2 spike (S)-protein with the company’s proprietary Trimer-Tag© technology. In preclinical studies, S-Trimer induced strong humoral and Th1-biased cell-mediated immune responses in multiple animal models and protects monkeys from SARS-CoV-2 challenge. Clover’s ongoing Phase 1 clinical trial is a randomized, observer-blind, placebo-controlled study to assess the safety, reactogenicity and immunogenicity of the COVID-19 S-Trimer vaccine at multiple dose levels. The study has completed enrollment of 150 adult and elderly participants, and will enroll an additional 200 participants at the selected dose in a Phase 1 dose-expansion study. Clover intends to initiate a global Phase 2/3 vaccine efficacy study before the end of 2020. Clover’s COVID-19 vaccine program is being supported by funding and collaboration with the Coalition for Epidemic Preparedness Innovations (CEPI).

About COVID-19 S-Trimer Vaccine
Utilizing Clover’s proprietary Trimer-Tag© technology, S-Trimer is a trimeric SARS-CoV-2 spike (S)-protein subunit vaccine candidate. Similar to other enveloped RNA viruses such as HIV, RSV and Influenza, SARS-CoV-2 is also an RNA virus that has a trimeric spike (S) protein on its viral envelope. The trimeric S protein of SARS-CoV-2 is responsible for binding to host cell surface receptor ACE2 and subsequent viral entry, making it the primary target antigen for vaccine development. S-Trimer resembles the native trimeric viral spike protein and is produced via a rapid mammalian cell-culture based expression system.
About Trimer-Tag© Technology
Trimer-Tag© is an innovative drug development platform which allows the production of novel, covalently-trimerized fusion proteins. Many major disease targets are trimerization-dependent such as the tumor necrosis factor (TNF) superfamily (involved in extrinsic apoptosis, immune co-stimulation and inflammation) as well as enveloped RNA virus antigens responsible for entry into host cells. Clover is using its Trimer-Tag© technology with global IP position to develop recombinant trimerized fusion proteins that are able to effectively target these previously undruggable pathways.
