A Preclinical Research job involves studying the safety, efficacy, and biological effects of new drugs, medical devices, or treatments before they are tested in humans. Researchers conduct laboratory experiments and animal studies to gather critical data on toxicity, pharmacokinetics, and mechanism of action. This phase ensures that only the most promising candidates proceed to clinical trials, minimizing risks for human participants. Preclinical researchers work in pharmaceutical companies, biotech firms, or academic institutions, collaborating with regulatory agencies to meet industry standards. Their findings play a key role in shaping drug development and approval processes.
