European Union (EU) guidelines are broader: they require all trials of medicinal products registered on their <a href=\"https:\/\/www.clinicaltrialsregister.eu\/\">EU Clinical Trials Registry (EUCTR)<\/a> since 2004 to report results within one year of completion. <a href=\"https:\/\/fdaaa.trialstracker.net\/\">Our FDAAA TrialsTracker<\/a> and <a href=\"https:\/\/eu.trialstracker.net\/\">EU TrialsTracker<\/a> show all individual trials that breach these legal requirements. Each week we write about one unreported clinical trial: you can read more background <a href=\"https:\/\/blogs.bmj.com\/bmj\/2018\/03\/29\/it-is-time-to-fix-the-problem-of-unreported-clinical-trials\/\">here<\/a>, and past entries are <a href=\"https:\/\/blogs.bmj.com\/bmj\/category\/unreported-trial-of-the-week\/\">here<\/a>.<\/p>\n<p><strong>Trial NCT02425683<\/strong><\/p>\n<p>This week\u2019s unreported trial is &#8220;Study of Colorectal Cancer Patients (Stage IIIC) With Either Regorafenib or Standard of Care (No Treatment) After Adjuvant FOLFOX&#8221; (<a href=\"https:\/\/clinicaltrials.gov\/ct2\/show\/NCT02425683?term=NCT02425683&amp;rank=1\">NCT02425683<\/a>). This was an open-label phase 2 interventional trial enrolling adult participants in the US after surgery. Regorafenib is currently <a href=\"https:\/\/www.medicines.org.uk\/emc\/product\/1263\">licensed for use<\/a> in patients with metastatic colorectal cancer (the participants in this trial), gastrointestinal stromal tumours and hepatocellular carcinoma. This was a complex trial with two stages: in the first stage, 50 patients were to be randomised to one of two starting doses, with the tolerated dose considered a primary outcome (alongside the number of patients completing a full 6 cycles); in the second stage there was a plan for a two arm trial of 214 participants comparing the dose from stage one against placebo. Secondary outcomes included overall survival, number of adverse events and disease-free survival, all up to 4.5 years follow-up. The study started in March 2015 and completed in September 2017.<\/p>\n<p><strong>Clinical discussion<\/strong><\/p>\n<p>Colorectal cancer (CRC) is the <a href=\"https:\/\/gut.bmj.com\/content\/66\/4\/683\">third most commonly diagnosed<\/a> malignancy and the fourth leading cause of cancer-related death in the world. It accounts for 12% of all <a href=\"https:\/\/www.cancerresearchuk.org\/health-professional\/cancer-statistics\/statistics-by-cancer-type\/bowel-cancer#heading-Zero\">new cancer cases<\/a> in the UK. 58% of patients diagnosed with stage III colon cancer and 68% of patients diagnosed with stage III rectal cancer have <a href=\"https:\/\/www.cancerresearchuk.org\/health-professional\/cancer-statistics\/statistics-by-cancer-type\/bowel-cancer\/diagnosis-and-treatment#heading-Four\">chemotherapy<\/a> as part of their primary cancer treatment. Patients with stage III colon cancer have a <a href=\"https:\/\/www.cancerresearchuk.org\/health-professional\/cancer-statistics\/statistics-by-cancer-type\/bowel-cancer\/survival#heading-Three\">5-year survival rate<\/a> of 63%. In 2013 <a href=\"https:\/\/www.ema.europa.eu\/en\/medicines\/human\/EPAR\/stivarga\">the EMA<\/a> approved regorafenib for metastatic colorectal cancer (mCRC) based on the <a href=\"https:\/\/www.thelancet.com\/journals\/lancet\/article\/PIIS0140-6736(12)61900-X\/fulltext\">CORRECT trial<\/a>. In 2015 <a href=\"https:\/\/www.nice.org.uk\/Guidance\/TA334\">NICE<\/a> terminated their appraisal of regorafenib for mCRC following no evidence submission from Bayer. As a result, the drug is not on the <a href=\"https:\/\/www.england.nhs.uk\/publication\/national-cancer-drugs-fund-list\/\">Cancer Drugs Fund (CDF)<\/a> for mCRC. The trial in question today was initiated after termination of the NICE appraisal.<\/p>\n<p><strong>Legislative discussion<\/strong><\/p>\n<p>This trial was terminated due to \u2018insufficient accrual\u2019 and has not reported results onto <a href=\"https:\/\/clinicaltrials.gov\/\">clinicaltrials.gov.<\/a> As discussed in previous installments of UTOTW: terminated trials that enrolled any patients are required to report their results, for the patients treated, directly onto ClinicalTrials.gov, under the FDAAA 2007. While terminated trials may not have enrolled sufficient patients to adequately assess their prespecified efficacy, effectiveness, or safety outcomes, the data collected may still be useful to inform clinical decision-making, resource allocation, and research. Although regorafenib is licensed in this indication already, the results of this trial may have provided insight into the most well-tolerated starting dose. Additionally, it may have contributed direct evidence or context on overall survival and disease-free survival for this drug, and similar treatments.<\/p>\n<p><strong>Conclusion<\/strong><\/p>\n<p>This unreported trial was sponsored by US Oncology Research in collaboration with Bayer Healthcare Pharmaceuticals. The PI is Thomas H. Cartwright, MD of McKesson Speciality Health. As of 25 February this trial is 157 days overdue to report. We hope the investigators will share the full results for this trial soon.<\/p>\n<p><em><strong><a href=\"https:\/\/blogs.bmj.com\/bmj\/files\/2019\/03\/Headshot.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-44214\" src=\"https:\/\/blogs.bmj.com\/bmj\/files\/2019\/03\/Headshot.png\" alt=\"\" width=\"160\" height=\"161\" srcset=\"https:\/\/blogs.bmj.com\/bmj\/files\/2019\/03\/Headshot.png 160w, https:\/\/blogs.bmj.com\/bmj\/files\/2019\/03\/Headshot-150x150.png 150w\" sizes=\"auto, (max-width: 160px) 100vw, 160px\" \/><\/a>Louisa Conlon<\/strong> is a clinical pharmacist in cancer services and current Chief Pharmaceutical Officer\u2019s clinical fellow<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/blogs.bmj.com\/bmj\/files\/2018\/03\/ben_goldacre.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-41742\" src=\"https:\/\/blogs.bmj.com\/bmj\/files\/2018\/03\/ben_goldacre.jpg\" alt=\"\" width=\"130\" height=\"130\" srcset=\"https:\/\/blogs.bmj.com\/bmj\/files\/2018\/03\/ben_goldacre.jpg 160w, https:\/\/blogs.bmj.com\/bmj\/files\/2018\/03\/ben_goldacre-150x150.jpg 150w\" sizes=\"auto, (max-width: 130px) 100vw, 130px\" \/><\/a><em><strong>Ben Goldacre<\/strong> is a doctor, author, and director of the EBM DataLab at the University of Oxford.
