Study Description

Brief Summary:

The primary objective of this trial is to establish the safety and tolerability of short-term (8 weeks) administration of mycophenolate mofetil in ambulatory children with JNCL. The secondary objective is to gather preliminary evidence of the short-term (8 week) impact of mycophenolate mofetil on clinically relevant features of JNCL as measured by the Unified Batten Disease Rating Scale (UBDRS), including motor features, seizures, behavior, cognitive and functional measures.

Juvenile Neuronal Ceroid Lipofuscinosis	Drug: Mycophenolate mofetil; Drug: Liquid Placebo	Phase 2

Detailed Description:

Juvenile Neuronal Ceroid Lipofuscinosis (JNCL) is a fatal disorder. Currently treatment is symptomatic. Thus, there is a real need to intervene and slow the progression of this disease. Preliminary data on genetic knock-down of the ability to mount an immune response in cln3-knockout mice is supportive of a strategy for treating JNCL with an immuno-suppressive agent. Many drugs with the ability to suppress the immune system are steroidal and deemed unsuitable for long-term administration to children. Mycophenolate mofetil (CellCept) is used as an immunosuppressive agent in allogenic transplants in pediatric patients and is therefore approved by the Food and Drug Administration (FDA) for pediatric use.

The study design is a double-blind, randomized, 22-week cross-over study of mycophenolate mofetil vs. placebo. After a 4-week washout period, subjects will undergo blinded crossover from active study drug to placebo or from placebo to active study drug.

Subjects and caregivers will be evaluated in person in the University of Rochester Batten Center (URBC) at screening/baseline, and at weeks 8, 12, and 20. In addition, subjects will be evaluated by their local clinician who is a formalized member of the research team. Such contacts will occur at Weeks 2, 4, 14, 16, and any unscheduled or early termination visits. There will also be regular telephone contact between the URBC and the local clinician.

We have selected the dosage currently FDA approved for use in children being treated for prophylaxis of renal transplant rejection.

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: Mycophenolate Mofetil	Drug: Mycophenolate mofetil; The liquid dosage will be individualized, contingent upon the subject's weight. Subjects will receive 50% of the target dose (300mg/m2/dose BID) during Week 0-Week 2, then increase to the full dose (600mg/m2/dose BID) in Week 3, continuing at this dose through Week 8. Additionally, due to the risk of gastrointestinal disturbance (hemorrhage, ulcer), children will also receive prophylactic Prilosec (Omeprazole) for the duration of the study, during both the mycophenolate and placebo arms.; Other Name: Cellcept
Placebo Comparator: Placebo liquid	Drug: Liquid Placebo; The dosage will be individualized, contingent upon the subject's weight. Subjects will receive 50% of the target dose (300mg/m2/dose BID) during Week 0-Week 2, then increase to the full dose (600mg/m2/dose BID) in Week 3, continuing at this dose through Week 8. Additionally, due to the risk of gastrointestinal disturbance (hemorrhage, ulcer), children will also receive prophylactic Prilosec (omeprazole) for the duration of the study, during both the mycophenolate and placebo arms.

Outcome Measures

Primary Outcome Measures :

1. Tolerability - Number of Participants Who Completed Each Arm on Assigned Study Drug Dose [ Time Frame: Baseline to 8 weeks ]
   The primary outcome measure is tolerability, defined as the completion of 8 weeks on the assigned dosage of study drug.

Secondary Outcome Measures :

1. Unified Batten Disease Rating Scale Physical Subscale Change [ Time Frame: Baseline to 8 weeks ]

   The Unified Batten Disease Rating Scale (UBDRS) is a disease-specific clinical assessment. Motor impairment was measured by the physical subscale of the UBDRS with a range of 0-112 with zero indicating better outcome.

   The overall treatment effect was determined - mean difference in physical subscale change (Mycophenolate minus placebo periods) in outcome, adjusted for baseline value and period effects.

2. Unified Batten Disease Rating Scale Seizure Subscale Change [ Time Frame: Baseline to 8 weeks ]

   The Unified Batten Disease Rating Scale (UBDRS) is a disease-specific clinical assessment. Seizure severity was measured by the seizure subscale of the UBDRS with a range of 0-54 with zero indicating better outcome.

   The overall treatment effect was determined - mean difference in seizure subscale change (Mycophenolate minus placebo periods) in outcome, adjusted for baseline value and period effects.

3. Unified Batten Disease Rating Scale Behavior Subscale Change [ Time Frame: Baseline to 8 weeks ]

   The Unified Batten Disease Rating Scale (UBDRS) is a disease-specific clinical assessment. Mood and behavior severity was measured by the behavior subscale of the UBDRS with a range of 0-55 with zero indicating better outcome.

   The overall treatment effect was determined - mean difference in behavior subscale change (Mycophenolate minus placebo periods) in outcome, adjusted for baseline value and period effects.

4. Unified Batten Disease Rating Scale Capability Subscale Change [ Time Frame: Baseline to 8 weeks ]

   The Unified Batten Disease Rating Scale (UBDRS) is a disease-specific clinical assessment. Capability severity was measured by the capability subscale of the UBDRS with a range of 0-14 with higher scores indicating better outcome.

   The overall treatment effect was determined - mean difference in capability subscale change (Mycophenolate minus placebo periods) in outcome, adjusted for baseline value and period effects.
