Phase I/II, Open-Label, Dose Escalation Study of the Safety, Pharmacokinetics and Pharmacodynamics of NV1205 in Pediatric Male Subjects With Childhood Cerebral Adrenoleukodystrophy (CCALD)

This study is to evaluate the safety, pharmacokinetics, and efficacy of NV1205 in pediatric patients diagnosed with childhood cerebral adrenoleukodystrophy (CCALD).

The study consists of:

• Screening period: within 30 days of first dose
• Main treatment period of 12 weeks (Part 1- from Screening to Week 12)
• Long Term Treatment (LTT) period (Part 2- Week 13 through Week 96)

In Part 1, subjects will have an initial 4-week treatment period at the assigned dose and, if no safety concerns are noted, subjects continue for another 8 weeks of extended safety assessment.

There will be several cohorts of subjects enrolled. After each Cohort has completed the 4-week initial safety assessment, the safety data will be reviewed by an independent Data Safety Monitoring Board (DSMB) and, subject to DSMB recommendation, Cohort 2 will be enrolled and receive the next dose level. After Cohort 2 has completed 4 weeks of treatment, the DSMB will review all available safety data (Cohorts 1 and 2) and, subject to DSMB recommendation, Cohort 3 will be enrolled and receive the next dose level. Additional Cohorts may be enrolled at the recommendation of the DSMB with an incremental dose increase.
