Merck (New Jersey, USA), using IBM Watson for Drug Discovery, automated the process of designing optimal clinical trial protocols and identifying suitable patient groups by analyzing medical data and literature. This reduced the patient recruitment period for Phase 2 trials from an average of 8 months to 4 months and increased the trial success rate from 67% to 84%. This effect is particularly pronounced in the field of rare diseases, where AI’s ability to leverage global medical databases to find suitable patients acts as a key competitive advantage in situations with limited patient numbers.

The third area is adverse effect prediction and drug safety evaluation technology. Pfizer (New York, USA) developed an AI safety evaluation system that can predict potential adverse effects with 89% accuracy before actual clinical trials, significantly reducing the risk of failure in late-stage trials. This system comprehensively analyzes molecular structures, existing toxicity data, and genomic information to evaluate drug hepatotoxicity, cardiotoxicity, and nephrotoxicity in advance. In fact, Pfizer reported that by 2025, it had identified potential safety issues early in 12 drug candidates, saving approximately $3.4 billion in development costs.

The market impact of these technological innovations is evident throughout the pharmaceutical industry’s value chain. Traditional CRO (Contract Research Organization) companies are making large-scale investments and acquisitions to secure AI capabilities, with IQVIA (North Carolina, USA) acquiring three AI startups for a total of $780 million in the first half of 2025 alone. Simultaneously, big tech companies are accelerating their entry into healthcare, with Microsoft (Washington, USA) launching its ‘Healthcare AI Suite’ based on its Azure cloud platform, currently used by over 240 pharmaceutical companies. Projects developed through this platform show an average 28% faster progress and a 19% reduction in development costs.
