Case Summary

​An anonymous, contactable member of the public complained about the information published as 'Clinical Trial Transparency: an assessment of the disclosure results of company-sponsored trials associated with new medicines approved recently in Europe'. The study was published in Current Medical Research & Opinion (CMRO) on 11 November 2013. The study authors were Dr B Rawal, Research, Medical and Innovation Director at the ABPI and B R Deane, a freelance consultant in pharmaceutical marketing and communications. Publication support for the study was funded by the ABPI.

The study surveyed various publicly available information sources for clinical trial registration and disclosure of results searched from 27 December 2012 to 31 January 2013. It covered 53 new medicines (except vaccines and fixed dose combinations) approved for marketing by 34 companies by the European Medicines Agency (EMA) in 2009, 2010 and 2011. It included all completed company-sponsored clinical trials conducted in patients and recorded on a clinical trial registry and/or included in a European Public Assessment Report (EPAR). The CMRO publication did not include the specific data for each product. This was available via a website link and was referred to by the complainant. The study did not aim to assess the content of disclosure against any specific requirements.

The complainant stated that the study detailed a number of companies which had not disclosed their clinical trial results in line with the ABPI for licensed products. The complainant provided a link to relevant information which included the published study plus detailed information for each product that was assessed.

The summary output for each medicine set out the sources for all trials found, irrespective of sponsor and an analysis of publication disclosure in the form of a table which gave details for the studies for Samsca (tolvaptan).

The detailed response from Otsuka is given below.

General detailed comments from the Panel are given below.

The Panel noted the CMRO publication in that 18 evaluable studies had not been disclosed within the timeframe. The disclosure percentage was 36%. Ten studies completed before the end of 2012 had not been disclosed. The disclosure percentage at 31 January 2013 of trials completed before the end of January 2012 was 64%. A footnote stated that the undisclosed Phase I/II trials comprised of trials completed before reporting requirements. Trials with no US IND therefore not subject to FDAAA 801 requirements. The undisclosed Phase III trial was being prepared for publication.

The Panel noted that Samsca was first approved on 5 May 2009. This meant that the 2008 Code applied and the Joint Position 2005. One trial with UK involvement completed in July 2006 and Otsuka submitted it was published in JAMA in March 2007. The study had been published within one year of Samsca being approved and commercially available as required. The Panel ruled no breach of the 2008 Code including Clause 2.

The Panel noted Otsuka's submission that seven other trials were either Phase 1 trials on healthy volunteers and/or used a different formulation of tolvaptan to that licensed. The Panel noted that the Joint Position 2005 did not require disclosure of exploratory trials unless they were of significant medical importance and might have an impact on the marketed product's labelling. The Panel was unsure whether the results were of significant medical importance. The complainant had not provided any details in this regard. The Panel considered publication of such data was preferable, however on the information before it there appeared to be no need to disclose the results of the trials under the 2008 Code. The Panel ruled no breach of the 2008 Code including Clause 2.
