Clinical Research Organizations (CROs) are specialized companies that support the pharmaceutical, biotechnology, and medical device industries in conducting clinical trials. They provide a range of services, including study design, patient recruitment, data management, and regulatory compliance, helping to ensure that new treatments are tested effectively and safely. CROs play a crucial role in the development of new drugs and therapies by managing the logistics of clinical studies. They work with regulatory agencies to ensure that trials meet legal and ethical standards, ultimately contributing to the approval of new medications and improving patient care.
