E.3 | Principal inclusion criteria |
• Male or female, 6 months of age or older •Prior participation in a clinical study assessing UX007/triheptanoin treatment for LC-FAOD. Study Sponsors/Collaborators include: Oregon Health & Science University, University of Pittsburgh, and Ultragenyx Pharmaceutical (ClinicalTrials.gov Identifiers: NCT01379625, NCT01461304, and NCT01886378). Patients who received UX007/triheptanoin treatment as part of other clinical studies; investigator sponsored trials (IST); expanded access/compassionate use treatment programs; or patients who are treatment naïve (i.e., naïve to both UX007 and food-grade triheptanoin), have failed conventional therapy and, in the opinion of the Investigator and Sponsor, have documented clear unmet need, may also be eligible at the discretion of the Sponsor. • Confirmed diagnosis of LC-FAOD including: carnitine palmitoyltransferase (CPT I or CPT II) deficiency, very long chain acyl-CoA dehydrogenase (VLCAD) deficiency, long chain 3-hydroxy-acyl-CoA dehydrogenase (LCHAD) deficiency, trifunctional protein (TFP) deficiency, or carnitine-acylcarnitine translocase (CACT) deficiency. Information on diagnosis will be obtained from medical records and should include confirmed diagnosis by results of acylcarnitine profiles, fatty acid oxidation probe studies in cultured fibroblasts, and/or mutation analysis. • Willing and able to complete all aspects of the study through the end of the study, including visits and tests, documentation of symptoms and diet, and administration of study medications. If a minor, have a caregiver(s) willing and able to assist in all applicable study requirements. • Provide written informed consent (subjects aged ≥ 18 years), or provide written assent (where appropriate) and have a legally authorized representative willing and able to provide written informed consent, after the nature of the study has been explained and prior to any research-related procedures. • Females of child-bearing potential must have a negative urine pregnancy test at Baseline and be willing to have additional pregnancy tests during the study. Females considered not of child-bearing potential include those who have not experienced menarche, are post-menopausal (defined as having no menses for at least 12 months without an alternative medical cause), or are permanently sterile due to total hysterectomy, bilateral salpingectomy, or bilateral oophorectomy. • Participants of child-bearing potential or fertile males with partners of child-bearing potential who are sexually active must consent to use a highly effective method of contraception as determined by the investigator from the period following the signing of the informed consent through 30 days after last dose of study drug. |
|
E.4 | Principal exclusion criteria |
• Diagnosis of MCAD deficiency, short- or medium-chain FAOD, ketone body metabolism defect, propionic acidemia or methylmalonic acidemia • Patient qualifies for any other clinical trial designed to progressively evaluate the safety and efficacy of triheptanoin in LC-FAOD • Any known hypersensitivity to triheptanoin that, in the judgment of the Investigator, places the subject at increased risk for adverse effects • Pregnant and/or breastfeeding an infant at Baseline or planning to become pregnant (self or partner) at any time during the study • Have any co-morbid conditions, including unstable major organ-system disease(s) that in the opinion of the Investigator, places the subject at increased risk of complications, interferes with study participation or compliance, or confounds study objectives, or unwilling to discontinue prohibited medications. |

E.5 End points |
E.5.1 | Primary end point(s) |
The annualized LC-FAOD major events rate inclusive of skeletal myopathy (rhabdomyolysis), hepatic (hypoglycemia) and cardiomyopathy events |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Throughout the trial (36 months), three relevant disease areas will be assessed, including at mos. 0, 6, 12, 18, 24, 30 and 36: 1) skeletal muscle - functional disability and creatine kinase (CK) levels, and 2) liver - metabolic effects on the liver and energy homeostasis, and at mos. 0, 12, 24 and 36, 3) cardiac disease - ventricle size, ejection fraction and shortening fraction.
In addition, FAOD-related laboratory measures assessed at mos. 0, 6, 12, 18, 24, 30 and 36.
Safety: events will be collected as AE/SAEs, including clinical laboratory tests, vital signs, physical examination, and concomitant medications. |
|
E.5.2 | Secondary end point(s) |
• Energy metabolism in LC-FAOD on the basis of the following endpoints: o Ventricle size o Ejection fraction (EF) o Shortening fraction (SF) • Clinical events associated with LC-FAOD on the basis of the following endpoints o Annualized duration rate of all MCEs o Annualized event rate of rhabdomyolysis MCEs o Annualized duration rate of rhabdomyolysis MCEs o Annualized event rate of cardiomyopathy MCEs o Annualized duration rate of cardiomyopathy MCEs o Annualized event rate of hypoglycemic MCEs o Annualized duration rate of hypoglycemic MCEs |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The effects of UX007 treatment on major clinical events will be assessed throughout the study (36 months). Major events are defined as musculoskeletal, hepatic, and cardiac events caused by LC-FAOD, or intercurrent illness complicated by LC-FAOD, resulting in any hospitalization, ER visit, or emergency intervention (any unscheduled administration of therapeutics at home or in the clinic). Assessed at months 0, 0.5, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, and 36. -Evaluate the effect of UX007 on energy metabolism in LC-FAOD by measuring total and free plasma carnitine, plasma actylcarnitines, and urine organic acids. Assessed at months 0, 6, 12, 18, 24, 30, and 36. |
