Summary of Clinical Use
The EMA and FDA have granted arimoclomol orphan drug status for the treatment of the neurodegenerative disease amyotrophic lateral sclerosis (ALS, aka Lou Gehrig's disease). A Phase II/III clinical trial assessing arimoclomol in ALS (NCT00706147) is ongoing.
Mechanism Of Action and Pharmacodynamic Effects
Arimoclomol acts as a coinducer of heat shock proteins (Hsps) [2] and this action has been reported to slow the process of motor neuron death and extend life in cellular and whole animal models of ALS [1,3-5,7]. Arimoclomol is reported to prolong the activation of heat shock transcription factor 1 (HSF1; Q00613), the master regulator of stress-inducible Hsps, including Hsp70 and Hsp90 [2]. Increased Hsp70 expression is believed to be responsible for the neuroprotective effect of arimoclomol in ALS mice [6].
