What Are the Bottlenecks in Traditional Drug Discovery Processes?
1. High Failure Rates
According to Nature Reviews Drug Discovery, approximately 90% of drugs entering clinical trials fail to reach FDA approval. The success rate is particularly low for certain areas like Alzheimer’s disease, where 99.6% of trials failed between 2002 and 2012.
2. Time-Intensive Process
The FDA reports that the average time from drug discovery to market approval takes 12 years. According to PhRMA (Pharmaceutical Research and Manufacturers of America), the preclinical phase alone typically requires 6.5 years of research. Just the initial target identification and validation phase can take 2-3 years, with multiple iterative testing cycles required at each stage.
3. Astronomical Costs
According to the Tufts Center for the Study of Drug Development, bringing a single drug to market costs approximately $2.6 billion. Failed candidates represent sunk costs that must be absorbed into the development costs of successful drugs.
4. Limited Testing Capacity
Physical lab testing constraints mean only a small fraction of potential drug compounds can be screened. Traditional high-throughput screening can test around 10,000 compounds per day – a tiny fraction of possible molecular combinations.
5. Data Integration Challenges
Scientists struggle to effectively integrate and analyze vast amounts of fragmented data from various sources – genomics, proteomics, clinical trials, and scientific literature – leading to missed insights and connections.
6. Target Selection Uncertainty
Identifying the right biological targets for drug intervention remains largely based on educated guesses. Many promising targets fail in later stages due to unforeseen complications or side effects.

AI in Drug Discovery is Great, But What About the Regulations?
FDA-approvals take a lot of time. AI-assisted drug discovery can help slash down the timeline and costs
The former MD of PayPal, Peter Thiel, once said, “If you’re trying to develop a new drug, that costs you a billion dollars to get through the FDA. If you want to start a software company, you can get started with maybe $100,000.”
He wasn’t joking. Approving drugs and the entire process around clinical trials after research is an expensive and time-consuming process.
So far, we have understood that AI carries the potential to vastly decrease the time taken to discover new drugs.
But where does the FDA stand on AI intervention in drug discovery?
In June 2023, the FDA released a discussion paper titled “Using Artificial Intelligence and Machine Learning in the Development of Drug and Biological Products.”
This document offers valuable definitions, distinguishing ML as a subset of AI. Moreover, highlighting that ML models are developed through data analysis without explicit programming.
The FDA acknowledges the increasing utilization of AI/ML in drug development. With a notable surge in AI/ML-based submissions, over 100 in 2021, covering drug discovery, clinical research, safety surveillance, and pharmaceutical manufacturing.
AI/ML is also being integrated into areas like Digital Health Technologies (DHTs) and Real-World Data (RWD) analytics. Here the FDA is actively engaged.
So far, the FDA is working on a flexible, risk-based regulatory framework that protects patient data and safety. While also allowing more AI-based innovation for companies.
This means, in a nutshell, the FDA has no significant concerns about the use of AI in drug discovery and development. This is a major win for the pharmaceutical companies looking to use AI in the US.
