Initially, researchers identify potential drug targets and compounds, which are then tested for efficacy and safety in vitro and in vivo. Successful candidates proceed to clinical trials, which are conducted in multiple phases to evaluate their effectiveness and safety in humans. Regulatory approval is sought from bodies like the FDA or EMA. This multifaceted process ensures that new drugs are both effective and safe for public use [2].
Historical challenges in drug development
Historically, drug development has faced significant challenges, including high costs, extensive timelines, and high failure rates. On average, bringing a new drug to market can take over a decade and cost billions of dollars. The attrition rate is high, with many compounds failing during preclinical testing or clinical trials due to safety concerns or lack of efficacy. Regulatory hurdles add another layer of complexity, as stringent requirements must be met to ensure patient safety. These challenges have often hindered the ability to quickly and efficiently bring new therapies to patients in need (Table 1).
