Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Safety, Efficacy, Therapy

To evaluate the safety and effectiveness of efavirenz (EFV) at an oral dose of 25 mg/d, in addition to standard treatment, in patients diagnosed with adult or late-onset juvenile type C Niemann-Pick disease (NP-C) with cognitive impairment.

Secondary objectives 4

  1. To assess the long-term safety of EFV in patients diagnosed with adult or late-onset juvenile NP-C with cognitive impairment,
  2. To evaluate the change in the Scale for the Assessment and Rating of Ataxia (SARA), Eating Assessment Tool score (EAT-10), and Pineda Disability Scale (PDS).
  3. To evaluate the change in the Clinical Dementia Rating Scale-Sum of Boxes (CDR-SoB), Free and Cued Selective Reminding Test (FCSRT), abbreviated Barcelona Test (a-BT), Verbal fluency (Semantic and phonetic cues), Trail Making Test (TMT) A and B, Stroop Color and Word Test (SCWT), Wechsler Adult Intelligence Scale (WAIS) and the block design, symbol search and vocabulary subtests (WAIS-III/WAIS-IV), Boston Naming Test (BNT) and the Naming and Semantic Knowledge subtests, Judgement of Line Orientation (JLO) Test, Dysexecutive Questionnaire (DEX), Neuropsychiatric Inventory (NPI), Apathy Evaluation Scale (AES), Beck’s Depression Inventory (BDI), and Columbia Suicide Severity Rating Scale (C-SSRS).
  4. To assess the change in imaging, functional, and plasmatic biomarkers.

IPD plan description
Deidentified IPD related to demographics, baseline characteristics, and primary and secondary outcomes will be made available by the Principal Investigator (PI), upon reasonable request from qualified academic researchers who submit a methodologically sound proposal. Access will be granted after approval of the proposal by the PI and, if applicable, an ethics committee. A data sharing agreement will be required.
