It typically takes over a decade and billions of dollars to bring a new drug to market, with a staggering 90% failure rate in clinical trials. This inefficiency not only strains healthcare systems but also delays critical treatments from reaching patients in need.

Enter AI-powered drug discovery. By leveraging advanced machine learning algorithms, natural language processing, and predictive modeling, AI is reshaping every stage of the pharmaceutical R&D pipeline:

1. Analysing vast amounts of data to identify promising drug candidates

2. Predicting drug-target interactions and potential side effects

3. Optimising molecular structures for better efficacy and safety

4. Designing and simulating clinical trials using extensive research and development

5. Personalising treatments based on individual patient data

So essentially, by leveraging AI, researchers can explore a much larger chemical space, test hypotheses faster, and make more informed decisions throughout the drug discovery pipeline. Let’s explore some of the organisations that are already leveraging the latest technology.
