A-Alpha Bio, a biotechnology company harnessing synthetic biology and machine learning to measure, predict, and engineer protein-protein interactions,  today announced $14.5M in additional funding from the Department of Defense (DOD) Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense’s (JPEO-CBRND's) Generative Unconstrained Intelligent Drug Engineering (GUIDE) program to further expand its partnership with Lawrence Livermore National Laboratory (LLNL), a federally funded research and development center. 

A-Alpha's partnership with LLNL began with $1M in funding in 2022 and was expanded in 2023 with an additional $2.4M, with funding provided by JPEO-CBRND GUIDE. This collaboration is aimed to preemptively generate data and train computational models that enable rapid medical countermeasures against potential future biothreats. The additional support will fund A-Alpha Bio’s generation of large-scale antibody-antigen binding datasets and enable training and validation of predictive computational models for multiple undisclosed pathogen families of concern.

GUIDE’s mission is to leverage integrated computational and experimental capabilities to accelerate drug development by harnessing the power of advanced simulation and machine learning. The program was established in response to the devastating effects of the COVID-19 pandemic, which highlighted the critical need for rapid medical countermeasures against novel biothreats. Since predicting the next specific biothreat is not possible, the DOD focuses on developing capabilities that will enable rapid response to any emerging challenge. Core to the program’s success is the ability to quickly and iteratively generate large-scale experimental data to train and validate predictive computational models. A-Alpha Bio was tapped to generate large-scale antibody-antigen binding data and enable the training and validation of predictive machine learning models. 

Over the past two years, A-Alpha and LLNL have demonstrated the success of their approach, first with coronaviruses and then with other select pathogen families of concern. Using its AlphaSeq platform, A-Alpha Bio experimentally measures millions of protein-protein interactions between thousands of pathogen variants and a diverse panel of antibody sequences. These multidimensional binding data are then integrated with LLNL’s high-performance computing. To date, nearly 10 million quantitative antibody-antigen binding affinities have been measured with AlphaSeq across three pathogen families and these data have enabled significant improvements in the accuracy of affinity-predicting machine learning models. Further, AlphaSeq data has been used to identify stabilized antigen variants and remove a significant obstacle to GUIDE’s success. These accomplishments over the past two years have prompted the additional funding to A-Alpha Bio.

“The past two years of collaboration with LLNL on the GUIDE program have seen remarkable success in training predictive machine learning models with high-throughput antibody-antigen binding data, and we are excited to expand our partnership with additional JPEO-CBRND support,” said Randolph Lopez, Ph.D. Chief Technical Officer at A-Alpha Bio. “There is an enormous need for biothreat preparedness, highlighted by the COVID-19 pandemic, but success here points to far broader drug discovery applications that will be enabled by high-throughput experimentation and machine learning, and we are excited to be at the center of these efforts.”
