NPC is a rare, relentlessly progressive, neurological disease and associated with serious morbidity and shortened life expectancy.

The purpose of this Expanded Access Program is to provide early access to arimoclomol for patients with Niemann-Pick Type C disease who, in the opinion and the clinical judgement of the treating physician, may benefit from treatment with arimoclomol.

Participants will receive treatment with arimoclomol until their doctor finds it does not help them anymore, they withdraw, or the study is stopped for any reason.

Inclusion Criteria:

• The patient has a confirmed diagnosis of NPC (NPC1 or NPC2)* and at least one neurological symptom.

• Confirmed negative urine pregnancy test for sexually active female of child-bearing potential (post-menarche).

• All sexually active male patients with female partners of child-bearing potential (postmenarche) agree to use a condom in addition to the birth control used by their partners during treatment and until three weeks after the last dose of arimoclomol.

• If the patient has a history of seizures, the condition must be adequately controlled, i.e., the pattern of seizure activity must be stable, and the patient must be on a stable dose and regimen of antiepileptic medication during one month prior to screening.
