Abstract:
Cancer therapeutics frequently lead to symptomatic adverse events (AE) that can affect treatment tolerability. The NCI has developed the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) to assess symptomatic AEs by direct patient self-report. Although longitudinal assessment of patient-reported symptomatic AEs holds promise to better inform treatment tolerability, using patient-reported outcome (PRO) measures to assess symptomatic AEs has raised several regulatory and good clinical practice issues among those who conduct cancer clinical trials. These include concerns regarding trial monitoring, clinical review of PRO results by investigators and delegated clinical staff, whether PRO data on symptomatic AEs require investigational new drug (IND) safety reporting, and how the trial conduct and resultant PRO data will be assessed during clinical investigator site inspections. This article addresses current thinking regarding these issues in cancer clinical trials from the FDA, the NCI, and the Office for Human Research Protections. PRO measures, such as PRO-CTCAE, that assess symptomatic AEs in cancer trials are considered similar to other PRO assessments of symptoms, function, and health-related quality of life and can generate complementary data that may inform tolerability. Clarity on operational concerns related to incorporating PRO measures to inform tolerability is critical to continue the advancement of rigorous PRO assessment in cancer clinical trials.

This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
