Conditions
Niemann-Pick Disease, Type C
Registration Number
NCT02435030
Lead Sponsor
ZevraDenmark
Brief Summary

This is a prospective non-therapeutic observational study in NP-C patients. The aim is to characterize the individual patient disease progression profile through the historical and 6 months prospective evaluation of clinical, imaging, biological(biomarkers) and quality of life data.

Patients will be offered enrollment into a Phase II/III study on arimoclomol at the end of the study.

Inclusion Criteria
  • Written informed consent (and assent if appropriate to local laws and regulations) prior to any study-related procedures;
  • Males and females aged from 2 years to 18 years and 11 months;
  • Patients of any ethnic background will be eligible for this study;
  • Patient weight ≥15th percentile of body mass index (BMI) for age according to the World Health Organisation (WHO) standards;
  • Diagnosis of Niemann Pick disease Type C (NP-C), either NPC1 or NPC2;
  • NP-C diagnosis genetically confirmed (deoxyribonucleic acid [DNA] sequence analysis);
  • Both NPC1 and NPC2 patients are eligible;
  • Presenting at least one neurological symptom of the disease (for example, but not limited to, hearing loss, vertical supranuclear gaze palsy, ataxia, dementia, dystonia, seizures, dysarthria, or dysphagia);
  • Ability to walk either independently or with assistance;
  • Ability to travel to the corresponding clinical trial site repeatedly (every 6 months) for evaluation and follow-up;
  • Treated or non-treated with miglustat;
  • If a patient is under prescribed treatment with miglustat, it has to be under stable dose of the medication for ≥ 3 continuous months prior to inclusion in the study;
  • Sexually active patients must be willing and able to use an adequate method of contraception throughout the study, for example: diaphragm + spermicide; intrauterine contraceptive device; oral contraceptives; implant; injection of a progestogen medication;
  • Ability to comply with the protocol-specified procedures/evaluations and scheduled visits;
  • Willing to participate in all aspects of trial design including serial blood sampling, skin biopsies and imaging (ultrasonography) collections.
Exclusion Criteria
  • No written informed consent obtained from the patient or their parent(s)/legal guardian(s) (and assent if appropriate to local laws and regulation) before any study related procedures;
  • Recipient of a liver transplant or planned liver transplantation;
  • Patients with uncontrolled severe epileptic seizures period (at least 3 consecutive severe epileptic seizures that required medication) within 2 months prior to the written consent. This includes patients with ongoing seizures that are not stable in frequency or type or duration over a 2 month period prior to enrollment, requiring change in dose of antiepileptic medication (other than adjustment for weight) over a 2 month period prior to enrollment, or requiring 3 or more antiepileptic medications to control seizures;
  • Neurologically asymptomatic patients;
  • Severe liver insufficiency (defined as hepatic laboratory parameters, aspartate transaminase [AST] and alanine transaminase [ALT] greater than three-times the upper limit of normal for age and gender;
  • Severe renal insufficiency, with serum creatinine level greater than 1.5 times the upper limit of normal ;
  • Severe manifestations of NP-C disease that would interfere with the patient's ability to comply with the requirements of this protocol;
  • In the opinion of the Investigator, the patient's clinical condition does not allow for the required blood collection and/or skin biopsies as per the protocol-specified procedures;
  • Treatment with any IMP within 4 weeks prior to the study enrollment;
  • Treatment with any IMP during the study in an attempt to treat NP-C;
  • Current participation in another trial is not permitted unless it is a non-interventional study and the sole purpose of the trial is for long-term follow up/survival data (registry);
  • Patients will be excluded if there is a confirmed risk linked to the MRI procedure to be performed in the subsequent therapeutic interventional study [i.e.: implanted cardiac pacemaker or implantable cardioverter defibrillator, implanted neural pacemakers, cochlear implants, implanted metallic foreign bodies in the eye or CNS (such as a CNS aneurysmal clip), any form of implanted wire or metal device that may concentrate radio frequency fields and/or confirmed history of unexpected serious adverse reaction to sedation or anesthesia (if sedation is necessary)];
  • Patients will be excluded if there is a confirmed risk linked to the skin punch biopsy procedure like severe thrombocytopaenia, at investigator's discretion.
