How Artificial Intelligence is Revolutionizing Drug Discovery
Artificial intelligence (AI) is transforming industries across the globe, from helping programmers write code to handling customer service inquiries through chatbots. But one sector where AI’s potential is still being tested is the pharmaceutical industry. Despite billions of dollars invested in research, developing new medicines remains a slow and expensive process, often taking a decade or more to bring a drug to market.
Enter Insitro, a South San Francisco-based company founded in 2018. Insitro is part of a growing wave of AI-driven companies aiming to accelerate drug discovery. By leveraging machine learning to analyze massive datasets of chemical and biological markers, Insitro hopes to uncover faster, cheaper ways to develop treatments for complex diseases. The company has already partnered with pharmaceutical giants like Eli Lilly and Bristol Myers Squibb to tackle metabolic diseases, neurological conditions, and degenerative disorders.
Daphne Koller, the CEO and founder of Insitro, recently spoke with the Associated Press about how AI is reshaping the challenges of drug discovery. Below are highlights from the conversation, which has been edited for clarity and length.
Understanding the Complexity of Drug Discovery
“The problem with drug discovery,” Koller explained, “is that we are trying to intervene in a system that we only slightly understand.” She noted that many of the pharmaceutical industry’s successes over the past 15 to 20 years have come from achieving a deeper understanding of biological systems. This understanding allows researchers to design interventions that align with the system’s intricacies.
At Insitro, the focus is on unraveling the complexity of heterogeneous diseases—conditions that manifest differently across patient populations. “We aim to identify new intervention modes that might not help the entire population but could be effective for a specific subset,” Koller said. This targeted approach could lead to more precise and effective treatments, addressing what she sees as a core issue in the industry’s lack of success.
The Role of Quantitative Biology
While AI often takes the spotlight, Koller highlighted another critical advancement: quantitative biology. This field involves measuring biological systems, such as proteins and cells, with unprecedented precision. “You can now measure these systems with increasingly better technology,” she said. However, the sheer volume of data generated can overwhelm human researchers.
“If you give that data to a person, their eyes will just glaze over,” Koller explained. “There’s only so much a person can perceive in terms of subtle differences.” This is where AI steps in, analyzing complex datasets to uncover patterns and insights that would be impossible for humans to detect. By combining AI with quantitative biology, Insitro aims to move beyond the reductionist views that have historically limited drug discovery.
A Personal Journey into AI and Biology
Koller’s journey into the intersection of AI and biology began in the late 1990s. With a PhD in computer science, she initially explored machine learning applications in less inspiring areas, such as classifying spam emails. “I was looking for something with more richness,” she said. Her search led her to biomedical problems, which presented more technically challenging questions. Over time, her interest in biology grew, and she became deeply invested in the field.
Bridging the Gap Between Engineers and Life Scientists
One of Insitro’s most significant achievements, according to Koller, has been fostering collaboration between engineers and life scientists. “You can take the most sophisticated, well-meaning scientists from either side and put them in the same room, and they might as well be speaking Thai and Swahili to each other,” she said.
Engineers often focus on identifying consistent patterns that can predict outcomes for the majority of cells or individuals. In contrast, life scientists tend to look for exceptions, as these anomalies can lead to groundbreaking discoveries. To bridge this gap, Insitro has implemented cultural and organizational practices that encourage open, constructive, and respectful communication between the two disciplines.
Key Takeaways
Insitro’s approach to drug discovery highlights several important trends in the pharmaceutical industry:
- Targeted Treatments: By focusing on subsets of patient populations, AI can help develop more precise and effective therapies.
- Data-Driven Insights: The combination of AI and quantitative biology enables researchers to analyze complex datasets and uncover patterns that would be impossible to detect manually.
- Interdisciplinary Collaboration: Bridging the gap between engineers and life scientists is crucial for leveraging the full potential of AI in drug discovery.
As AI continues to evolve, its impact on the pharmaceutical industry could be transformative. Companies like Insitro are at the forefront of this revolution, using cutting-edge technology to tackle some of medicine’s most challenging problems. While the road ahead is uncertain, the promise of faster, cheaper, and more effective drug development is a goal worth pursuing.
