Lugano, Switzerland, Puteaux, France, October 9, 2019 – Helsinn, a Swiss pharmaceutical group focused on building quality cancer care products, today announces it will be co-hosting alongside Recordati Rare Diseases, a worldwide leader in rare diseases and orphan drugs, part of Recordati Group, a satellite symposium at the 28th European Academy of Dermatology and Venereology (EADV) Congress, held this year in Madrid from 9 – 13 October 2019.

The symposium will be co-hosted alongside Recordati Rare Diseases and will be entitled: An MF-CTCL path free of potholes: avoiding misdiagnosis and optimizing the patient journey. The event will take place at 17:00–18:30 on 10 October 2019 in Room N115–116, North Convention Centre, IFEMA – Feria de Madrid.

This symposium will bring together three experts (Emmilia Hodak, Pablo Ortiz-Romero, Pietro Quaglino) involved in the treatment of Cutaneous Lymphoma who will give an overview on Mycosis Fungoides-type Cutaneous T-cell Lymphoma (MF-CTCL). Additionally, they will discuss on the patient journey, particularly focusing on diagnosis and occurrences of misdiagnosis. There will also be a discussion around the real-world experience with chlormethine gel (Ledaga®) and how it can be used in the treatment of MF-CTCL.

Dr Silvia Sebastiani, Helsinn Head of Medical Affairs, commented: “We are pleased to be hosting a symposium alongside our partner Recordati Rare Diseases in order to raise awareness and stimulate debate on how to optimize the diagnosis of MF-CTCL, whose delay has a devastating impact on patient’s quality of life.

“As specialist in rare disease, at RRD we know how important it is, even with an efficient drug such as Ledaga® to support more than only the treatment of the disease. This is part of our responsibility as leading company in Orphan diseases” said Dr Céline PLISSON Global Medical Director from RRD “and we are pleased to have the opportunity to help patients and physicians to better manage this rare and psychologically heavy pathology”.

Pablo Ortiz-Romero, MD, PhD, Hospital Universitario 12 de Octubre, Madrid, Spain and Chair of the Symposium said: “One of the issues with MF-CTCL is that it can be very hard to diagnose as each patient often presents different symptoms and MF-CTCL frequently mimics other skin conditions. Helsinn and Recordati Rare Diseases have come together to co-host this symposium today so together we can highlight this disease and help educate patients and clinicians about the signs, symptoms and treatment options that will, ultimately, help patients get better treatment and give them a better quality of life.”

About Mycosis Fungoides

Mycosis fungoides (MF) accounts for almost 60% of all primary cutaneous T-cell lymphomas, a form of non-Hodgkin’s lymphoma. The cause of MF remains unknown and there are no curative treatments. MF has an indolent clinical course, slowly progressing from patches to thicker plaques and eventually to tumours over years or decades. Signs include rash, patch and plaques with severe itch. MF typically affects older adults (median age at diagnosis: 55-60 years) with male predominance. However, people of all ages can be affected. Depending on the stage and diagnosis at presentation, life expectancy can vary from less than five years after diagnosis to full life expectancy. Evidence from seven global studies (US, n = 4; Europe, n = 3) indicated that the incidence of CTCL has increased over time, reaching ∼10 cases per million individuals per year.
