A therapeutically effective amount of deferiprone or deferasirox or physiologically acceptable salts thereof for the prevention, stabilization, treatment, or reversal of iron-induced FRDA disease in patients resulting from mitochondrial iron-induced damage to preferentially reduce the iron stores in the mitochondria. Also for the treatment of other conditions affecting the brain where a key element in the generation of the resultant pathology is the intracellular mishandling of iron.

The present invention relates to processes for the preparation of deferasirox, an oral iron chelator developed to treat iron overload due to e.g. multiple blood transfusions. The present invention further provides novel deferasirox pseudopolymorphs and a novel amorphous form of deferasirox, processes for their preparation, as well as pharmaceutical compositions comprising same, and use thereof in treating iron overload.

Methods and pharmaceutical compositions for preconditioning and / or providing neuroprotection to the animal central nervous system against the effects of neurological disorders involving ischemia, trauma, metal poisoning and neurodegeneration, including the associated cognitive, behavioral and physical impairments. In one embodiment, the method is accomplished by stimulating and / or stabilizing hypoxia-inducible factor-1α (HIF-1α). HIF-1α is known to provide a neuroprotective benefit under ischemic conditions. In another embodiment, the method is accomplished by differentially reducing, inhibiting or preventing the increased expression of selected genes caused by neurological disorders. Patients at risk for certain diseases or disorders that are associated with risk for cerebral ischemia may benefit, e.g., those at risk for Alzheimer's disease, Parkinson's disease, Wilson's disease, Huntington's disease, thalassemia or stroke, or those patients having head or spinal cord injury. Patients undergoing certain medical procedures that may result in ischemia may also benefit. Initially, the possibility of ischemia or neurodegeneration is recognized. Intranasal therapeutic agents are administered to the upper third of the nasal cavity to bypass the blood-brain barrier and access the central nervous system directly to avoid unwanted and potentially lethal side effects. Therapeutic agents include those substances that interact with iron and / or copper such as iron chelators, copper chelators, and antioxidants. Particular examples of such therapeutic agents are the iron chelators deferoxamine (DFO) and deferasirox. Intranasal administration of DFO is known to stimulate and / or stabilize HIF-1α and provides an efficient and safe method for pre-conditioning the brain to protect against cerebral ischemia.

Formulations and methods are provided for improving the function, i.e. clinical outcome, of solid organ transplants. Lung transplantation is of particular interest. In the methods of the invention, a nanoparticle formulation comprising an effective dose of an iron chelator active agent in nanoparticle form, including without limitation, deferoxamine (DFO), deferasirox (DFX), and deferiprone (DFP), etc. suspended in a carrier compatible with the tissue of interest, is topically applied to the surface of tissues at the site of anastomosis. The nanoparticles are comprised of the active agent and a pharmaceutically acceptable stabilizer.
