Final answer:
True, a sponsor-investigator can be a corporation, such as a pharmaceutical company, which is tasked with initiating and overseeing clinical trials, including postmarketing Phase IV trials for drug safety surveillance.
Step-by-step explanation:
The statement in question, whether a sponsor-investigator may be a corporation such as a pharmaceutical company, is true. A sponsor-investigator in the context of clinical trials and FDA regulations can indeed be a corporation. Such entities are often responsible for initiating and overseeing the conduct of clinical trials, including Phase IV trials, which are part of postmarketing risk management strategies.
Under FDA requirements, these corporations may be tasked with conducting additional clinical trials post-approval to monitor drug safety and efficacy. Furthermore, they may need to implement risk management plans that could encompass various forms of studies, restrictions, or safety surveillance activities to ensure the ongoing safety of a drug.
