MAINZ, Germany and LONDON, United Kingdom - January 11, 2022 (Investorideas.com Newswire) BioNTech SE (Nasdaq: BNTX, "BioNTech") and InstaDeep Ltd ("InstaDeep") today announced the development of a new computational method that analyses worldwide available sequencing data and predicts high-risk variants of SARS-CoV-2. The Early Warning System (EWS) developed in collaboration by BioNTech and InstaDeep is based on artificial intelligence (AI) calculated immune escape and fitness metrics.
The new method combines structural modeling of the viral Spike protein and AI algorithms to quickly flag potential high-risk variants entered into SARS-CoV-2 sequence data repositories within less than a day based on metrics scoring their fitness (e.g. ACE2 and variant Spike protein interaction) as well as their immune escape properties. The companies validated these predictions using experimental data generated in-house and publicly available data.
During the trial period, the system has identified >90% of the World Health Organization (WHO)-designated variants (Variants of Concern, VOC; Variants of Interest, VOI; Variants Under Monitoring,VUM) on average two months in advance. WHO-designated variants Alpha, Beta, Gamma, Theta, Eta and Omicron were detected by the EWS in the same week its sequence was first uploaded. The Omicron variant was ranked as a high-risk variant the same day its sequence became available. The IHU variant observed in France has also been evaluated by the EWS, which highlighted immune escape properties that are relatively similar to Omicron but with significantly lower fitness, making it less of a concern given current data.
The results from the study underline that the EWS is capable of evaluating new variants in minutes and risk monitoring variant lineages nearly in real-time. It is also fully scalable as new variant data becomes available.
"With the advanced computational methods we have been developing over the past months we can analyse sequence information of the Spike protein and rank new variants according to their predicted immune escape and ACE2 binding score," said Ugur Sahin, M.D., Chief Executive Officer and Co-Founder of BioNTech. "Early flagging of potential high-risk variants could be an effective tool to alert researchers, vaccine developers, health authorities and policy makers, thereby providing more time to respond to new variants of concern."
"More than 10,000 novel variant sequences are currently discovered every week and human experts simply cannot cope with complex data at this scale. We've addressed this challenge by deploying the powerful AI capabilities of InstaDeep's DeepChain platform combined with BioNTech's SARS-CoV-2 know-how and technology. For the first time, high-risk variants could be detected on the spot, potentially saving months of precious time. We are happy to make our research work publicly available and, most importantly, look forward to its continued real-world impact," added Karim Beguir, Co-Founder and CEO of InstaDeep.
The Early Warning System (EWS) relies on two approaches: (1) structural modeling of the interaction of the viral Spike protein receptor-binding domain (RBD) with the host cell receptor and scoring the impact of the virus variant in escaping the immune response, and (2) AI-based predictive modeling to extract information from hundreds of thousands of registered virus variants from global sequence repositories. The EWS computes an immune escape score and a fitness (transmissibility potential) prior score. While the immune escape score alone was already highly predictive of the risk, combining these two metrics into a Pareto score provided the best assessment of the risk posed by a given virus variant. The higher the score, the higher the risk of the variant impacting global health. The EWS approach ranks SARS-CoV-2 variants for immune escape and fitness potential based solely on existing data, and therefore is not dependent on a "wait-and-watch" approach.
The EWS was able to distinguish the WHO-designated variants from those that had no designation during a 11-month period, underlining the viable computational model ability to determine variant lineage. An analysis conducted every week between September 16th, 2020 and November 23rd, 2021 flagged 12 out of 13 WHO-designated variants with an average of 58 days of lead time (i.e. two months) before the variants were given their designation. For variants Alpha to Mu, only around 25 cases on average were recorded at the time of them being flagged by the EWS. This is in contrast with the WHO announcements that happened on average when more than 1,500 cases were recorded. The EWS detected Omicron on the day its sequence was first uploaded as the highest immune escaping variant from over more than 70,000 variants that were discovered between early October 2021 and late November 2021 while also assigning it a high fitness score.
The data published as a pre-print is the result of a collaboration established between BioNTech and InstaDeep in November 2020 to coalesce AI and immunology. As part of the collaboration, the companies formed a joint AI Innovation Lab in London, UK, and Mainz, Germany, to advance novel drug discovery and design, protein engineering, manufacturing and supply chain optimization.
About SARS-CoV-2 Mutations
The last two years have demonstrated how the frequent and wide circulation of the SARS-CoV-2 virus increases its likelihood to mutate in parts of its genetic make-up with the potential to change its features. Current known variants harbor mutations that distinguish them from the original strain identified in early 2020. Over 13,400 individual missense mutations have been observed in the Spike protein alone. Available data show that thousands of new variants are emerging every week at an increasing rate, with a weekly average of registered variants of about 300 in September 2020, 7,000 in August 2021 and 12,000 in December 2021.
While most mutations either reduce the overall fitness of the virus, or bear no consequences to its features, some individual or combinations of mutations lead to high-risk variants (HRVs) with modified immune evasion capabilities and/or improved transmissibility. A variant that can bypass neutralization by antibodies is of particular importance and poses a risk to individuals who previously had COVID-19 and those that are fully vaccinated.
As new sequences continue to be detected in infected individuals, foreseeing variants that have the potential to become HRVs is critical for pandemic preparedness. Identifying these variants creates a significant challenge for public health authorities as detection by varied tests in the lab is very time consuming. The EWS allows for early detection of these variants and shortens the time that health authorities need to assess their impact and respond in a timely manner.
