BeiGene Announces an Exclusive License Agreement on Neutralizing Antibodies against SARS-CoV-2 Developed by Singlomics

Phase 1 and 1/2 clinical trials are expected to be initiated by early October this year to enroll healthy subjects and patients with mild to moderate symptoms of COVID-19 infections, respectively.

On August 27, 2020, BeiGene (NASDAQ: BGNE; HKEX: 06160) and Singlomics Biopharmaceuticals Co., Ltd. announced they have entered into an exclusive license agreement. BeiGene will further develop, manufacture, and commercialize neutralizing antibodies against SARS-CoV-2 (including DXP-593 and DXP-604) under development by Singlomics globally, but outside Greater China. In preclinical studies, Singlomics have screened out several potent neutralizing antibodies against SARS-CoV-2 from blood samples of convalescent COVID-19 patients by using the high-throughput single-cell sequencing technology.

 

Academician Xiaoliang Xie, Lee Shau-kee Chair Professor of Peking University, Director of Beijing Advanced Innovation Center for Genomics, and Co-founder & Chairman of the Scientific Advisory Board of Singlomics, said: "Our goal is to find potent neutralizing antibodies against SARS-CoV-2 as quick as possible. We aim to develop a potential treatment regimen which can greatly benefit broader patient populations than those treated by the convalescent plasma therapy."

 

Dr. Xu Zhang, Co-founder and CEO of Singlomics, said: "We believe that working with BeiGene can effectively push these significant scientific achievements into the next stage of development. BeiGene’s global clinical development team of more than 1,300 employees has the ability to reach out around the world to bring innovative therapies to patients in need."

 

 

Dr. Lai Wang, Senior Vice President of BeiGene, Head of Global Research, Clinical Operations & Biostatistics and Head of Asia-Pacific Clinical Development, commented: "Professor Xiaoliang Xie has made a major breakthrough in the study of antibodies against SARS-CoV-2, and has screened out antibodies expected to neutralize

SARS-CoV-2 by using the high-throughput single-cell sequencing technology. We are pleased to be able to initiate a clinical trial for this exciting drug candidates and to contribute to the development of novel therapies for the global fight against COVID-19 epidemic."

 

A randomized, double-blind, placebo-controlled Phase 1 clinical trial is expected to be initiated in Australia in September,  enrolling up to 30 healthy subjects, while Phase 1/2 clinical trials to be conducted in multiple countries will be initiated by early October to enrol patients with mild to moderate symptoms of COVID-19 infections. Information on both clinical trials will be published on clinicaltrials.gov.

 

Under the terms of the Agreement, Singlomics has authorized BeiGene exclusive rights to develop, manufacture, and commercialize its preclinical drug candidates DXP-593, DXP-604, and other neutralizing antibodies against SARS-CoV-2 outside Greater China. BeiGene plans to develop one or more drug candidates globally outside Greater China, while Singlomics will retain relevant rights in Greater China. Singlomics will receive an upfront payment from BeiGene and be eligible to receive payment after the latter reaching the registration and milestone of commercialization. In addition, Singlomics will be eligible to receive graded royalties from BeiGene’s sales of the future products at a two-digit percentage ratio.

 

About DXP-593 and DXP-604

 

 

DXP-593 and DXP-604 are two neutralizing antibodies against SARS-CoV-2, screened from the memory B cells specific for the viral spike protein harvested from more than 60 convalescent COVID-19 patients. The antibody discovery was accomplished by using the high-throughput single-cell transcriptome and VDJ sequencing technologies. In biological assays, DXP-593 demonstrated strong neutralizing activity against SARS-CoV-2 pseudoviruses and live viruses, with half maximal inhibitory concentration (IC50) measured as 1.2 ng/ml and 15 ng/ml, respectively. In rodent models infected with SARS-CoV-2, DXP-593 also showed a strong curative and preventive effect. The binding epitope of DXP604 is different from that of DXP593, and it also showed distinctly neutralizing activity. The pairing of DXP593 and DXP604 are expected to be a highly competitive cocktail therapeutic option for the treatment of COVID-19 infections, especially in combatting drug resistance caused by viral mutations.
