  • Method of Evidence-Based Evaluation on Off-label Uses

    Objective To introduce the evidence-based evaluation on off-label uses at home and abroad, so as to investigate a systematic method of evidence-based evaluation on off-label uses. Methods In combination with the domestic and international research literature, a systematic method of evidence-based evaluation on off-label uses was discussed from the following three aspects: sources of evidence, levels of evidence, and recommendation strength. Results Sources of evidence included Clinical Pharmacology, DRUGDEX? System, NCCN Drugs amp; Biologics Compendium and handsearched literature. Levels of evidence and recommendation strength could refer to the 2009 grade system of Oxford Centre for Evidence-Based Medicine, and the strength of recommendations and scientific support of DRUGDEX? System. Conclusion A systematic method of evidence-based evaluation on off-label uses is initially established.

  • Off-label Use of Aspirin in Outpatients of Sun Yat-sen Memorial Hospital in 2013: A Retrospective Survey

    ObjectiveTo understand the situation of off-label use of aspirin among outpatients in Sun Yatsen Memorial Hospital, so as to provide baseline data for developing off-label drug use policy. MethodsA stratified random sampling method was used to collected prescription data of aspirin among outpatients in 2013. The incidence rates between different types of off-label use of aspirin were determined by chi-square test, and the influence factors of off-label drug use were analyzed by logistic regression model. ResultsA total of 5 023 prescriptions with aspirin were collected and analyzed, with incidence rate of off-label use up to 17.7%. The major category of off-label use was no indication (94.38%). The top 3 no indications were recurrent abortion, infertility and systemic lupus erythematosus. Drug specification, gender, age and prescribed department were the risk factors of off-label use. ConclusionAspirin off-label use is common among outpatients in Sun Yat-sen Memorial Hospital in 2013, especially in obstetrics and gynecology department and assisted reproductive center. The results suggest that more clinical studies about aspirin for reproduction are needed to provide more evidence of drug use, so as to ensure the safety of drug use in special populations and avoid potential medical risk.

  • Key considerations for using real-world evidence to support label expansions

    With the real-world study (RWS) becoming a hotspot for clinical research, health data collected from routine clinical practice have gained increasing attention worldwide, particularly the data related to the off-label use of drugs, which have been at the forefront of clinical research in recent years. The guidance from the National Medical Products Administration has proposed that real-world evidence (RWE) can be an important consideration in supporting label expansions where randomized controlled trials are unfeasible. Nevertheless, how to use the RWE to support the approval of new or expanded indications remains unclear. This study aims to explore the structured process for the use of RWE in supporting label expansions of approved drugs, and to discuss the key considerations in such process by reviewing the documents from relevant regulatory agencies and publications from public databases, which can inform future directions for studies in this area.
