Aliança internacional d’afectats per l’atàxia de Friedreich per finançar el projecte de teràpia gènica desenvolupat a Espanya

Aliança internacional d’afectats per l’atàxia de Friedreich per finançar el projecte de teràpia gènica desenvolupat a Espanya.

Científics de l’Institut de Recerca Biomèdica (IRB) i el Centre de Biologia Molecular Severo Ochoa (CBMSO) van iniciar el projecte dos mesos enrere.

El projecte és fruit de la iniciativa d’afectats espanyols units en la plataforma Genefa en col·laboració amb la Federació d’Atàxies d’Espanya i BabelFAmily. Ara, s’hi suma The Friedreich's Ataxia Research Alliance (FARA), una de les principals organitzacions de pacients dels Estats Units.

L’aportació de FARA suposa el 50% del pressupost total de 300.000€ del projecte. Els fons de FARA provenen del suport de les famílies dels pacients i comunitats afins dels EUA, i d'altres agents internacionals com FARA-Irlanda.

International patient advocates partner to fund Spanish gene-therapy project to treat Friedreich's ataxia

International patient advocates partner to fund Spanish gene-therapy project to treat Friedreich's ataxia

January 28, 2014

Scientists at the Institute for Research in Biomedicine (IRB) and the “Centro de Biología Molecular Severo Ochoa” (CBMSO) launched the project two months ago.

The project is the result of an initiative of Spanish people affected by this rare disease who are grouped in GENEFA in collaboration with the Spanish Federation of Ataxias and the BabelFAmily. The Friedreich’s Ataxia Research Alliance (FARA), one of the main patients’ associations in the United States now joins the endeavour.

The support provided by FARA will account for 50% of the project budget of 300,000 euros. Of note, FARA’s funds come from the support of patient families and communities raising funds at a grassroots level and from other International advocates such as FARA – Ireland.

FXN GAA repeat expansions in amyotrophic lateral sclerosis

FXN GAA repeat expansions in amyotrophic lateral sclerosis. Naji Rizik, Axel Freischmidt, Albert C. Ludolph, Jochen H. Weishaupt; ournal of Clinical Neuroscience, Available online 27 January 2014. http://dx.doi.org/10.1016/j.jocn.2013.10.029

When homozygously present, an increased number of GAA repeats in the FXN gene results in a severely decreased expression of frataxin, resulting in the manifestation of FRDA. However, even heterozygous expansion of the trinucleotide repeat substantially reduces frataxin expression. Heterozygous expansion carriers are usually normal, but still display an increased risk for pathological glucose tolerance and, thus suggesting that a heterozygous FXN mutation leads to a borderline impairment of specific cell types at risk.

Optimizing Mouse Models of Neurodegenerative Disorders

Optimizing Mouse Models of Neurodegenerative Disorders. Future Neurology. Cathleen M Lutz, Melissa A Osborne; Future Neurology. 2014;9(1):67-75.

This experience in SMA raises interesting questions for FRDA. Does such a threshold also exist in FRDA models, where no or too low frataxin results in embryonic lethality, but levels of 10% or more result in mice that are phenotypcially normal? Can mice simply tolerate low levels of frataxin? Alternatively, perhaps FRDA is not just a disease of low frataxin protein, but insread is one in which the GAA repeat itself plays a greater role in the disease course, beyond just inhibiting transcription. Would mouse models of higher repeat length or uninterupted repeats produce a more robust phenotype? Additional FRDA models are desperately needed in order to help address these questions.

A Phase IIa Trial to Test Safety and Efficacy Interferon Gamma Treatment in Elevating Frataxin Levels in FRDA Patients. ClinicalTrials.gov

Sponsor: Azienda Policlinico Umberto I

The primary objective of this study is to investigate whether the treatment with IFN gamma can induce significant accumulation of frataxin in FRDA patients, a possibility suggested by pre-clinical evidence in an animal model of the disease.

Detailed Description:
This is a Phase 2 clinical trial. A total of 10 FRDA patients will be recruited All subjects will be treated with a dose of 100-150-200-micrograms of IFN gamma 1b (Imukin®) subcutaneously, with an interval of 14 days, for a total of 3 injections.
