Use of PRO Measures to Inform Tolerability in Oncology Trials: Implications for Clinical Review, IND Safety Reporting, and Clinical Site Inspections.

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.

Off-label use of medicine in pediatrics: focus on gastrointestinal diseases.

PURPOSE OF REVIEW: To provide current information on off-label medication use in pediatric gastroenterology, including a discussion on US legislative efforts to address the issue. RECENT FINDINGS: Medications used to treat pediatric gastrointestinal illnesses are frequently prescribed off-label. Acid suppressors, antiemetics, laxatives, and antitumor necrosis factor therapies are types of medications frequently used off-label in the pediatric gastroenterology arena. Pediatric studies conducted under US Federal laws are generating much-needed data on the safety and effectiveness of medications used to treat pediatric patients. Moreover, a new US law, the Food and Drug Administration Safety and Innovation Act, may further the development of pediatric medications in part by requiring pediatric-specific study plans earlier in the overall drug development process. As of today, there still are gaps in our knowledge about these medications, including for the treatment of pediatric gastroenterology diseases. SUMMARY: Medications are widely used off-label in pediatrics, including medications intended to treat gastrointestinal diseases, such as antitumor necrosis factor and laxatives. Although legislation is helping to generate and make available important information about pediatric medications, most still do not contain pediatric data. Therefore, providers need to understand the potential risks and benefits of prescribing off-label products to pediatric patients.
