Therefore, moving beyond mere collaboration and focusing on fostering developing ecosystems will be key for small biotechs to thrive as integral players in the pharmaceutical R&D landscape. In summary, while there are notable milestones in integrating AI into drug discovery, the path forward is fraught with both technical challenges and regulatory scrutiny, highlighting the need for continuous investment and strategic planning within the industry.

2. Evolution of AI in Drug Discovery

  • 2-1. Early applications of AI in pharmaceuticals

  • The integration of artificial intelligence (AI) into pharmaceutical research and drug discovery can be traced back to initial developments in the 1970s and 1980s. During this period, early applications were limited, as interest receded due to unmet expectations and the high complexity of biological systems. By the mid-1990s, advancements in computing technology and the explosion of data availability began to change this landscape. The use of AI in drug discovery primarily unfolded through the establishment of expert systems and the advent of machine learning algorithms. It was not until the early 2010s that AI began to gain traction, largely led by breakthroughs in deep learning that allowed for more sophisticated analyses of biomedical data. This resurgence was characterized by a dramatic increase in the number of AI-driven biotech startups focusing on drug development.

  • 2-2. Major milestones from 2016 through 2024

  • Between 2016 and 2024, the use of AI in drug discovery saw significant milestones. Notably, major pharmaceutical companies, including Pfizer, Sanofi, and GSK, embarked on strategic collaborations with AI technology providers such as IBM Watson, Recursion Pharmaceuticals, and Exscientia. These partnerships aimed to optimize candidate drug selection, enhance efficiency in preclinical studies, and analyze extensive clinical datasets rapidly. Despite the promising developments, one critical outcome during this period deserves attention: as of early 2025, no AI-discovered drug had received FDA approval. This reflects the ongoing challenges in navigating the regulatory landscape and achieving reproducible results in clinical settings, underscoring the gap that still existed between innovation and practical application.

  • Additionally, the implementation of AI models began to impact the efficiencies of drug development processes dramatically, with companies reporting potential reductions in both time and cost of development. For instance, the ability of AI to sift through millions of potential compounds far exceeded traditional methods, positioning AI as a fundamental tool in identifying viable drug candidates. Moreover, the trend toward personalized medicine began to gain momentum, with AI facilitating the identification of specific patient populations that would benefit most from particular therapies.

  • 2-3. Transition from hype to targeted R&D use

  • As the hype surrounding AI subsided, pharmaceutical companies shifted from broad theoretical applications to targeted R&D initiatives. Increased scrutiny revealed AI's limitations and necessitated a focus on integrating AI technologies into specific stages of drug development. By the end of 2024, a distinct trend emerged where companies began utilizing AI to enhance their capabilities in drug repurposing, toxicity prediction, and pharmacogenomics — fields where the potential for AI was more clearly applicable.

  • Nevertheless, the landscape remained challenging, with experts highlighting that while AI could support various processes, its capacity to replace traditional methods was not yet realized. This phase marked a pivotal change wherein stakeholders recognized the need for rigorous validation and a paradigm shift in regulatory approaches to fully harness AI's potential in drug discovery. Educational initiatives and collaborative frameworks to foster deeper understanding and application of AI technologies among researchers further underscored this transition.
