Use of Patient-Reported Outcomes to Understand & Measure the Patient Experience of Novel Cell and Gene Therapies.

ABSTRACT

Patient reported outcomes (PROs) are the gold standard for assessing patients' experience of treatment in oncology, defined in the 21st Century Cures Act as information about patients' experiences with a disease or condition, including the impact of a disease or condition, or a related therapy or clinical investigation on patients' lives; and patient preferences with respect to treatment of their disease or condition [1]. PROs provide a comprehensive assessment of the benefits and risks of new medical products, as well as essential data to inform real-world use. Although RCTs are the ultimate source for information for evaluating products in development, they are not always feasible for rare diseases with few or no effective treatment options available. Thus, it is important to consider other measures that can help to improve the strength of evidence for cell and gene therapies targeting rare indications. While collection of PROs and other patient experience endpoints does not resolve the difficulty of conducting trials in small populations, doing so contributes empirical evidence that informs both product development and patient access. Additionally, including routine collection of PROs in registries may provide supplemental data to further characterize the benefitrisk profile of cell and gene therapies at follow-up times that would be infeasible to operationalize in a clinical trial setting.
