Physicians and medical staff from 12 countries and 2 1 European EPP expert centres discussed the ongoing treatment of adult patients diagnosed with EPP, the post-authorisation obligation for collection of pseudonymised data ( patients’ identifying details are coded ), and the clinical relevance of the treatment with SCENESSE® (afamelanotide 16mg). EUROPEAN POST-AUTHORISATION SAFETY STUDY (PASS) CLINUVEL is required to conduct a post-authorisation safety study (PASS), as agreed with the European Medicines Agency (EMA) in October 2014, capturing data on the ongoing safety and use of SCENESSE ® in adult EPP patients participating in the European EPP Disease Registry (EEDR). Initial formal analyse s of data from the EEDR consisted of approximately 34,000 patient -days- exposure to treatment between 22 June 2016 and 30 June 2017 . The data showed an unchanged safety profile for SCENESSE® compared to the Summary of Product Characteristics (SmPC). As one of the measures of clinical effectiveness it was found that, as of 30 June 2017, 99% of the EPP patients were still continuing treatment. Further analyses of clinical effectiveness are being conducted for those EPP patients who continue treatment and those who received their first treatment after 30 June 2017. Of interest was that 6 1% of the patients receiving SCENESSE ® had been ‘treatment naïve’ prior to participating in the PASS, in that they had not received afamelanotide during CLINUVEL’s clinical trial program from 2005 to 2013, or through compassionate use or special access schemes. Following the initial d ata presented during the European expert meeting discussion s were held on the overall clinical experience with the medicinal drug. The general observations from the attending medical staff was that SCENESSE® provided therapeutic value under real-world conditions and that it enabled EPP patients to engage in daily activities which had not been previously possible. None of the attending porphyrinologists declared a conflict of interest and all provided an opinion in an independent capacity. 2 Of particular interest was that under conditions of use , 16% of the EPP patients sought treatment during the autumn and winter months. Medical staff from the expert centres expressed that a higher number of parents and carers had requested afamelanotide treatment for children diagnosed with EPP since the treatment for adults had been made available. In the coming year CLINUVEL intends to discuss with the EMA suggested changes to the SmPC, in particular to widen the recommended maximum dosing of SCENESSE® per calendar year. COMMENTARY “The feedback on real -life clinical experiences from EPP patients and physicians is very important to us and provides significant information for future development,” CLINUVEL’s Director of Clinical Affairs, Dr Emilie Rodenburger said. “ The efforts of physicians and medical staff to treat patients under the strict ly imposed post- authorisation measures need to be acknowledged . It is highly motivating and satisfying to learn first -hand the impact of the work done by CLINUVEL’s team i n assisting patients who had not been clinically attended before. I also take away from this meeting how much experts have appreciated our team’s ability to persevere under all circumstances.” - End – 1 SCENESSE® (afamelanotide 16mg) is approved in Europe as an orphan medicinal product for the prevention of phototoxicity in adult patients with EPP.
