These three studies focus specifically on hernia repair, bunionectomy, and abdominoplasty. The most recent <a href=\"https:\/\/www.cdc.gov\/nchs\/data\/nhsr\/nhsr102.pdf\" target=\"_blank\" rel=\"noopener\">US surgical statistics<\/a> estimate that 777,000 hernia repairs and 379,000 bunion and toe deformity operations took place in 2010, while the <a href=\"https:\/\/www.plasticsurgery.org\/documents\/News\/Statistics\/2016\/plastic-surgery-statistics-full-report-2016.pdf\" target=\"_blank\" rel=\"noopener\">American Society of Plastic Surgeons<\/a> estimated that 127,633 abdominoplasty surgeries we conducted in 2016. This means over 1 million patients are undergoing these three operations each year, leading to significant opportunities for post-operative pain. New and innovative therapies in the area could have huge impacts on patient morbidity and quality of life. These three unreported trials may have important information for patients.<\/p>\n<p><strong>Legislative Discussion<\/strong><\/p>\n<p>We intend that this series should occasionally shed light on interesting issues around transparency rules, and how registry data is used. You can read some general background about the FDA Amendments Act 2007\u2014and why a trial is considered \u201cdue\u201d\u2014<a href=\"https:\/\/www.biorxiv.org\/content\/early\/2018\/03\/12\/266452\" target=\"_blank\" rel=\"noopener\">here<\/a> and <a href=\"https:\/\/ebmdatalab.net\/why-is-this-trial-due-to-report\/\" target=\"_blank\" rel=\"noopener\">here<\/a>.<\/p>\n<p>Simple Google searches reveal a complex patchwork of published results related to HTX-011 in the form of <a href=\"https:\/\/www.herontx.com\/sites\/default\/files\/pdfs\/posters-presentations\/ACS_2017_Synergy_Presentation_D6.pdf\" target=\"_blank\" rel=\"noopener\">interim<\/a> <a href=\"https:\/\/www.journalacs.org\/article\/S1072-7515(17)31227-9\/pdf\" target=\"_blank\" rel=\"noopener\">results<\/a> at <a href=\"https:\/\/www.herontx.com\/sites\/default\/files\/pdfs\/posters-presentations\/Heron_PainWeek_2016_Hernia_Results_L2c_091516.pdf\" target=\"_blank\" rel=\"noopener\">conferences<\/a> or <a href=\"https:\/\/www.herontx.com\/sites\/default\/files\/pdfs\/corporate-presenations\/HeronWebsitePresentation_March2018.pdf\" target=\"_blank\" rel=\"noopener\">corporate presentations<\/a>. As we have discussed in previous installments of this series, the FDAAA 2007 requires results to be reported directly onto <a href=\"http:\/\/clinicaltrials.gov\/\" target=\"_blank\" rel=\"noopener\">ClinicalTrials.gov<\/a>. Results being spread out among interim conference presentations and corporate presentations is confusing and makes it difficult to gather and critically appraise the evidence. The evidence shows that trial reports in journals or other mediums is also often <a href=\"http:\/\/journals.plos.org\/plosmedicine\/article?id=10.1371\/journal.pmed.1001566\" target=\"_blank\" rel=\"noopener\">incomplete <\/a>compared to <a href=\"http:\/\/annals.org\/aim\/fullarticle\/1852869\/reporting-discrepancies-between-clinicaltrials-gov-results-database-peer-reviewed-publications\" target=\"_blank\" rel=\"noopener\">registry reporting<\/a>.<\/p>\n<\/div>\n<div>\n<p>Since HTX-011 is an unapproved therapy, the trial sponsor could have requested certificates of delay, which would allow them to delay results reporting up to 2 additional years (or 30 days following approval). None of these three trials contain any indication that these delays have been granted. Per the <a href=\"https:\/\/www.gpo.gov\/fdsys\/pkg\/FR-2016-09-21\/pdf\/2016-22129.pdf\" target=\"_blank\" rel=\"noopener\">FDAAA Final Rule<\/a> (\u00a711.44), sponsors are required to apply for certificates of delay before results would otherwise have been due; although our work has already shown that this aspect of the law is apparently <a href=\"https:\/\/blogs.bmj.com\/bmj\/2018\/05\/15\/unreported-clinical-trial-of-the-week-brexpiprazole-for-the-treatment-of-subjects-with-agitation-associated-with-alzheimers-type-dementia-nct01922258\/\" target=\"_blank\" rel=\"noopener\">not being enforced<\/a>. Each of these trials was due to report results by either February or March 2017: note that whole months are given, but no exact completion date, for any of the three studies, which is also a breach of the <a href=\"https:\/\/prsinfo.clinicaltrials.gov\/definitions.html\" target=\"_blank\" rel=\"noopener\">legal responsibilities of the sponsor to maintain accurate study dates<\/a>.<\/p>\n<p>Corporate <a href=\"https:\/\/herontherapeutics.gcs-web.com\/news-releases\/news-release-details\/heron-therapeutics-announces-initiation-phase-3-program-htx-011\" target=\"_blank\" rel=\"noopener\">press materials<\/a> indicate that Heron Therapeutics has presented their Phase 2 data to the FDA and has been granted <a href=\"https:\/\/www.businesswire.com\/news\/home\/20171026005576\/en\/Heron-Therapeutics-Granted-FDA-Fast-Track-Designation\" target=\"_blank\" rel=\"noopener\">fast track status<\/a> as they undertake phase 3 trials. The fast track designation was granted in October 2017, prior to the results of these trials becoming due, but after more accurate completion date information should have been provided. It is concerning that a sponsor granted \u201cfast track\u201d status is not being required to accurately maintain the registry entries for the trials that formed the basis of that \u201cfast track\u201d status. This is especially troubling when the organisation granting this special fast track designation\u2014the FDA\u2014is also in charge of enforcing the rules around accurate data on <a href=\"http:\/\/clinicaltrials.gov\/\" target=\"_blank\" rel=\"noopener\">ClinicalTrials.gov<\/a>.<\/p>\n<p><strong>Conclusion<\/strong><\/p>\n<\/div>\n<div>These unreported trials were sponsored by Heron Therapeutics. The company has given no information on <a href=\"http:\/\/clinicaltrials.gov\/\" target=\"_blank\" rel=\"noopener\">clinicaltrials.gov<\/a> to identify the Principal Investigator for any of the three studies.
