A team of 37,000 AI agents analyzed over 55,000 clinical trials and identified the protein CD276 as a promising target for lung-cancer treatment. The Virtual Biotech system, described in Science, also found that drugs targeting proteins active in specific cell types were nearly 50% likelier to reach market. The findings have not yet been validated through experiments or clinical trials.

Key Facts

The Virtual Biotech system comprises up to 37,000 AI agents that autonomously interact with large language models.
The system analyzed published results of more than 55,000 clinical trials for drugs across a wide range of conditions.
Drugs targeting proteins active in specific cell types were nearly 50% likelier to reach market compared to other drugs.
The AI team identified the protein CD276 as a promising therapeutic target for lung cancers.
The study was led by James Zou, a computer scientist at Stanford University in California, and published in Science.

Virtual Biotech Architecture

The Virtual Biotech mirrors the staff of a biotechnology company, with a chief scientific officer agent directing employees in different divisions. Divisions include target identification and clinical-trial design, each with their own subspecialities. The system used versions of Claude, developed by Anthropic in San Francisco, as the underlying large language model. James Zou, a computer scientist at Stanford University, led the effort and says any advanced LLM will do, including open-source models.

Clinical Trial Analysis

Zou's team tasked the Virtual Biotech with analyzing published results of more than 55,000 clinical trials. The chief scientific officer assigned 37,075 agents to each tackle a single later-stage trial. Other virtual biotech employees searched for predictors of success in data sets showing which genes were active in different cell types. This analysis found that drugs targeting proteins active in specific cell types were nearly 50% likelier to reach market.

CD276 Target Investigation

In another demonstration, Zou's team directed the chief scientific officer to investigate whether the protein CD276 would make a good therapeutic target for lung cancers. The system identified CD276 as a promising target, though the predictions were not validated through experiments or clinical trials. Other scientists note that the Virtual Biotech has not been vetted in real-world drug discovery.
