Summary

AWS and the Gray Lab at Johns Hopkins Whiting School of Engineering have launched the Antibody Developability Benchmark, a novel, large-scale dataset designed to evaluate AI-guided antibody design models. This benchmark addresses the critical need for a public, diverse dataset to assess the trustworthiness and performance of in-silico tools for drug discovery, which has been hindered by existing datasets' limitations in scope and heterogeneity. It features 50 seed antibodies across four structural formats (IgG, VHH, NearGermline-IgG, scFv) targeting 42 antigens, measuring six key developability traits like expression and thermostability. Crucially, the dataset includes engineered variants with both favorable and unfavorable developability outcomes, all validated through wet-lab experiments, and supports zero-shot learning for robust model evaluation. The benchmark results are now available via Amazon Bio Discovery, with additional benchmarks and a detailed paper expected later this year.

Key takeaway

For AI Scientists and Research Scientists developing or evaluating biological foundation models for antibody design, this new benchmark offers an unprecedented opportunity. You can now rigorously compare model performance against a diverse, experimentally validated dataset, significantly reducing the uncertainty and cost associated with early-stage drug discovery. Integrating this benchmark into your development workflow will enhance confidence in your models' predictions before committing to expensive wet-lab experiments, ultimately accelerating therapeutic antibody development.

Key insights

A new diverse, experimentally validated dataset enables rigorous benchmarking of AI models for antibody developability.

Principles

Method

The Antibody Developability Benchmark was created by systematically engineering variants of 50 seed antibodies, using both pLM-guided and non-pLM-guided mutation strategies, and validating all outcomes via wet-lab experiments.
