The primary purpose of this study is to evaluate the safety and tolerability of arimoclomol in ALS patients following 90 days of dosing. In addition, the amount of arimoclomol in blood and cerebrospinal fluid will be measured.
Arimoclomol is a small molecule that upregulates "molecular chaperones" in cells under stress. Arimoclomol extends survival by five weeks when given both pre-symptomatically and at disease onset in a mutant superoxide dismutase (SOD1) transgenic mouse model of ALS. Furthermore, it has been demonstrated to have neuroprotective and neuroregenerative effects in other rat models of nerve damage. Molecular chaperone proteins are critical in the cellular response to stress and protein misfolding. Recent data suggest that the SOD1 mutation responsible for ALS in some patients with familial disease reduces the availability of a variety of molecular chaperones, and thus weakens their ability to respond to cellular stress. Protein misfolding and consequent aggregation may play a role in the pathogenesis of both the familial and sporadic forms of ALS. Therapeutic agents such as arimoclomol that improve cellular chaperone response to protein misfolding may be helpful in ALS.

A glutamate antagonist (RECEPTORS, GLUTAMATE) used as an anticonvulsant (ANTICONVULSANTS) and to prolong the survival of patients with AMYOTROPHIC LATERAL SCLEROSIS.
A superoxide dismutase (SOD1) that requires copper and zinc ions for its activity to destroy SUPEROXIDE FREE RADICALS within the CYTOPLASM. Mutations in the SOD1 gene are associated with AMYOTROPHIC LATERAL SCLEROSIS-1.
Diseases characterized by a selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. Clinical subtypes are distinguished by the major site of degeneration. In AMYOTROPHIC LATERAL SCLEROSIS there is involvement of upper, lower, and brainstem motor neurons. In progressive muscular atrophy and related syndromes (see MUSCULAR ATROPHY, SPINAL) the motor neurons in the spinal cord are primarily affected. With progressive bulbar palsy (BULBAR PALSY, PROGRESSIVE), the initial degeneration occurs in the brainstem. In primary lateral sclerosis, the cortical neurons are affected in isolation.

A Poly(A) RNA-binding protein that negatively regulates EGFR ENDOCYTOSIS. An increased risk for developing AMYOTROPHIC LATERAL SCLEROSIS 13 is observed in patients who have more than 23 CAG repeats in the ATXN2 gene coding sequence. Larger CAG expansions in the ATXN2 gene occur in SPINOCEREBELLAR ATAXIA 2 patients.
A widely-expressed protein of approximately 400 to 500 amino acids. Its N-terminal region (DENN domain) interacts with RAB GTP-BINDING PROTEINS and may regulate AUTOPHAGY, as well as PROTEIN TRANSPORT to ENDOSOMES. Expansion of the GGGGCC hexanucleotide repeat in the first intron of the C9orf72 gene is associated with FRONTOTEMPORAL DEMENTIA with AMYOTROPHIC LATERAL SCLEROSIS (FTDALS1).
