CyNCh is a multi-center, placebo-controlled clinical trial of children ages 8 to 17 years with biopsy-confirmed moderate to severe nonalcoholic fatty liver disease (NAFLD). The primary objective is to evaluate whether 52 weeks of treatment with cysteamine bitartrate delayed-release capsules will result in improvement in liver disease severity.

Primary Outcome Measures:
  • Improvement in NAFLD [ Time Frame: 52 weeks ]
    Centrally scored and masked assessment of histologic improvement in NAFLD between the baseline liver biopsy and follow-up biopsy after 52 weeks of treatment, where improvement is defined as: (1) decrease in NAS of 2 or more and (2) no worsening of fibrosis.

Secondary Outcome Measures:
  • Reduction in serum aminotransferase and gamma-glutamyl transpeptidase [ Time Frame: 52 weeks ]
  • Reduction in MRI-determined hepatic fat fraction [ Time Frame: 52 weeks ]
  • Changes to markers of oxidation and anti-oxidant status: malondialdehyde, F2alpha-isoprostane, total antioxidant capacity, oxidized LDL [ Time Frame: 52 weeks ]
  • Changes in fasting insulin and glucose [ Time Frame: 52 weeks ]
  • Changes in weight, height, BMI, and waist circumference [ Time Frame: 52 weeks ]
  • Changes in the Pediatric Quality of Life score [ Time Frame: 52 weeks ]
  • Changes to any symptoms the patient may have experienced [ Time Frame: 52 weeks ]
  • Proportion with a change from a histological diagnosis of definite NASH or indeterminate for NASH to not NASH at end of treatment [ Time Frame: 52 weeks ]
  • Individual histological characteristics at end of treatment compared to baseline such as steatosis, lobular inflammation, portal chronic inflammation, ballooning, fibrosis score and stage 1a vs 1b fibrosis [ Time Frame: 52 weeks ]
  • Change in mean NAFLD Activity Score (NAS) [ Time Frame: 52 weeks ]

Ages Eligible for Study:   8 Years to 17 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Children age 8-17 years
  • Liver biopsy obtained within 90 days of screening visit and not more than 120 days before randomization
  • Clinical history consistent with NAFLD
  • Definite NAFLD based upon liver histology
  • No evidence of any other liver disease by clinical history or histological evaluation
  • A histological severity of: NAFLD Activity Score (NAS) ≥ 4.
  • Sexually active female participants of childbearing potential (i.e., not surgically sterile [defined as tubal ligation, hysterectomy, or bilateral oophorectomy]) must agree to utilize the same two acceptable forms of contraception from screening through completion of the study and to complete a serum pregnancy test at each study visit. The acceptable forms of contraception for this study include hormonal contraceptives (oral, implant, transdermal patch, or injection) at a stable dose for at least 3 months prior to screening, and barrier (condom with spermicide, diaphragm with spermicide). Sexual activity will be ascertained at each study visit for post-menarchal females and if sexually active, subject must verify use of the same 2 acceptable forms of contraception. For pre-pubescent children, a documented attestation of abstinence from their parent or guardian will be acceptable.
  • Participants must be able to swallow DR Cysteamine tablets with the tablet intact
  • Written informed consent from parent or legal guardian
  • Written informed assent from the child

Exclusion Criteria:

  • There will be no exclusion criteria based on race, ethnicity or gender.

    • Seizure disorder
    • Active coagulopathy
    • Gastrointestinal ulcers/bleeding
    • Renal dysfunction with a creatinine clearance < 90 mL/min/m2
    • History of active malignant disease requiring chemotherapy within the past 12 months prior to randomization
