2019 International Machado Joseph Disease Research Conference - Washington, DC USA

MJD Conf Washington Group Shot 2

In response to a question posed in the patient panel for the recent International Machado Joseph Disease Research Conference, respected neuroscientist Professor Luis Almeida noted that “we actually live in exciting moments in terms of planning new therapies… some years ago you would not have seen all these different approaches that we know are very promising because they were effective in the animal models… today if you look around you see that there are people from different (pharmaceutical) companies who are here in this meeting and this is a fantastic sign, they are interested, they believe that the technologies that have developed over the last few years will work and be effective and will alleviate the disease..  so I think that we should have a positive view  –we have never had such a good moment as we have now…”

For participants of the meeting and those they represent who are living with Machado-Joseph disease (MJD) – the most common spinocerebellar ataxia worldwide, these are welcome words indeed.  While it is not possible to put an exact time frame on the development of a treatment, there was ample evidence in the packed program of marked progress in molecular and gene therapies.  This  brings with it the need to focus on ensuring people living with MJD are ‘trial ready’ and that clinicians and lab scientists are able to identify and utilise appropriate biomarkers of the disease.   

The conference was held in Washington DC on the 12th and 13th of November as a satellite of the third International Ataxia Research Conference (IARC) held from November 14th-16th.  Researchers from ten countries attended and presented outcomes correlated with 5 themes:  Contextual care and innovation in MJD care in low resourced and culturally complex contexts; Pre-clinical and Drug therapies - information, advances and collaboration; Gene therapies; Disease mechanisms: Pathogenesis & Biomarkers and Clinical research and practice.

MJD Foundation Chairperson Neil Westbury and Vice Chairperson Gayangwa Lalara along with Director for Research & Education Libby Massey and several MJDF staff, (one client and 3 therapists) made the long trip from Australia and were enthusiastic about the strong positive messages that can be brought home.  Neil thanked the presenters for their commitment and particularly noted the importance of ongoing international collaborations across all spheres of disease management and treatment.  

The conference was supported by  GEMCO (South 32), The Telstra Foundation, ALCGEAT, the Lowitja Institute and James Cook University,   and would not have been possible without the superb efforts of the Scientific committee: Jorge Sequeiros, Thorsten Schmidt, Manuela Lima, Luis Pereira de Almeida, Laura Bannach Jardim, Patricia Maciel, Tomer Hiller, Libby Massey and Desireé La Grappe.  The organisers of IARC - Ataxia UK, FARA (USA) and NAF (USA) - also provided invaluable advice and support.
