RESUMEN

BACKGROUND: The risk of pancreatitis and potential risk of medullary thyroid carcinoma associated with glucagon-like peptide-1 receptor agonists prompted the US Food and Drug Administration to require a Risk Evaluation and Mitigation Strategy for albiglutide, including education for prescribers and subsequent assessment of their knowledge of the risks and safe use of albiglutide via a quantitative survey. OBJECTIVE: The objective of this study was to assess prescribers' knowledge of the risks related to medullary thyroid carcinoma, pancreatitis, and the appropriate patient population for albiglutide. METHODS: Two Risk Evaluation and Mitigation Strategy surveys were conducted 18 months and 3 years after albiglutide was launched. Primary analyses evaluated correct response rates for each question. Secondary analyses evaluated the number of correct responses and the percentage of respondents scoring at/above the target comprehension thresholds (75% at 18 months; 80% at 3 years), which were selected based on discussion with the Food and Drug Administration and current standards for Risk Evaluation and Mitigation Strategy assessments, for each key risk message. RESULTS: The correct response rate for individual questions ranged from 68.2 to 97.9% (18-month survey) and from 69.4 to 98.1% (3-year survey). For the secondary analysis, 79.5, 86.7, and 86.7% of respondents in the 18-month survey answered ≥ 75% of the questions correctly and 70.8, 90.9, and 54.1% of respondents in the 3-year survey answered ≥ 80% of the questions correctly for key risk messages related to medullary thyroid carcinoma, pancreatitis, and appropriate patient population, respectively. CONCLUSIONS: Survey results indicated most, but not all, prescribers are knowledgeable regarding the risks and safe use of albiglutide. Additional education to address gaps in knowledge could further improve risk mitigation.
