## Clinical trials: Challenges Facing the Gold Standard

Clinical trials represent the final pivotal step in an often complex development process, before a drug reaches patients. To this day, clinical trials remain the gold standard for demonstrating that drugs are safe and effective before they are introduced to patients. In recent years, the global clinical trials landscape has expanded dramatically, reaching five times its 2005 size by 2024. This growth has been accompanied by the evolving complexity of contemporary medical research, including advances in personalised medicine, and emerging therapeutic modalities, such as cell and gene therapies, immunotherapy, and precision oncology.    
However, despite the remarkable evolution of medical research, many clinical trials still rely on legacy processes that are time-consuming, expensive, and operationally inefficient. The pharmaceutical industry invests approximately USD 200 billion annually in R&D, with only a 12% success rate for drug approvals. Phase III clinical trials cost an average of USD 19 million and can take six to seven years to complete. As the industry advances towards increasingly complex and personalised therapeutic approaches, these limitations become even more evident, highlighting the need for a more modern and scalable clinical trial ecosystem.
