Randomized, double-blind, placebo-controlled study of interferon-γ 1b in Friedreich Ataxia

In vitro, in vivo, and open-label studies suggest that interferon gamma (IFN-γ 1b) may improve clinical features in Friedreich Ataxia through an increase in frataxin levels. The present study evaluates the efficacy and safety of IFN-γ 1b in the treatment of Friedreich Ataxia through a double-blind, multicenter, placebo-controlled trial. Ninety-two subjects with FRDA between 10 and 25 years of age were enrolled. Subjects received either IFN-γ 1b or placebo for 6 months. The primary outcome measure was the modified Friedreich Ataxia Rating Scale (mFARS). No difference was noted between the groups after 6 months of treatment in the mFARS or secondary outcome measures. No change was noted in buccal cell or whole blood frataxin levels. However, during an open-label extension period, subjects had a more stable course than expected based on natural history data. This study provides no direct evidence for a beneficial effect of IFN-γ1b in FRDA. The modest stabilization compared to natural history data leaves open the possibility that longer studies may demonstrate benefit.

Therapeutic Prospects for Friedreich's Ataxia

Friedreich's ataxia (FRDA) is a progressive disease affecting multiple organs that is caused by systemic insufficiency of the mitochondrial protein frataxin. Current therapeutic strategies aim to elevate frataxin levels and/or alleviate the consequences of frataxin deficiency. Recent significant advances in the FRDA therapeutic pipeline are bringing patients closer to a cure.

The Role of Iron in Friedreich's Ataxia: Insights From Studies in Human Tissues and Cellular and Animal Models

Friedreich's ataxia (FA) is a rare early-onset degenerative disease that affects both the central and peripheral nervous systems, and other tissues, mainly the heart and pancreas. This disorder progresses as a mixed sensory and cerebellar ataxia, primarily disturbing the proprioceptive pathways in the spinal cord, peripheral nerves and nuclei of the cerebellum. FA is an inherited disease caused by an insufficient amount of the nuclear-encoded mitochondrial protein frataxin, which is an essential and highly evolutionary conserved protein whose deficit results in iron metabolism dysregulation and mitochondrial dysfunction. The first experimental evidence connecting frataxin with iron homeostasis came from yeast; iron accumulates in the mitochondria of yeast with deletion of the frataxin equivalent gene. This finding was soon linked to previous observations of iron deposits in the hearts of FA patients and was later reported in animal models of the disease. Despite advances made in the understanding of FA pathophysiology, the role of iron in this disease has not yet been completely clarified. Some of the questions still unresolved include the molecular mechanisms responsible for the iron accumulation and iron-mediated toxicity. Here, we review the contribution of the cellular and animal models of FA and relevance of the studies using FA patient samples to gain knowledge about these issues. Mechanisms of mitochondrial iron overload are discussed considering the potential roles of frataxin in the major mitochondrial metabolic pathways that use iron. We also analyzed the effect of iron toxicity on neuronal degeneration in FA by reactive oxygen species (ROS)-dependent and ROS-independent mechanisms. Finally, therapeutic strategies based on the control of iron toxicity are considered.

Progress in understanding Friedreich's ataxia using human induced pluripotent stem cells

Neuronal and cardiac cells are primary targets of frataxin deficiency and generating models via differentiation of induced pluripotent stem cells (iPSCs) into these cell types is essential for progress towards developing therapies for FA. This review is focused on modeling FA using human iPSCs and various iPSC-differentiated cell types. The authors emphasize the importance of patient and corrected isogenic cell line pairs to minimize effects caused by biological variability between individuals.

The versatility of iPSC-derived cellular models of FA is advantageous for developing new therapeutic strategies, and rigorous testing in such models will be critical for approval of the first treatment for FA. Creating a well-characterized and diverse set of iPSC lines, including appropriate isogenic controls, will facilitate achieving this goal. Also, improvement of differentiation protocols, especially towards proprioceptive sensory neurons and organoid generation, is necessary to utilize the full potential of iPSC technology in the drug discovery process.

C-Path and FARA announce the launch of the FA Integrated Clinical Database

Critical Path Institute's (C-Path) Data Collaboration Center (DCC) and the Friedreich's Ataxia Research Alliance (FARA) today announced the launch of the Friedreich's Ataxia Integrated Clinical Database (FAICD). The new platform will enable collaborative research and data sharing to support the understanding of natural history, potential biomarkers and clinical endpoints, and promote research into novel clinical trial design in Friedreich's ataxia (FA). By making this data available to researchers, the organizations hope to enable the development of tools that will help design and interpret efficient clinical trials — leading to effective treatments for FA as soon as possible.
