Trial Outcomes & Findings for A Study of UX007 (Triheptanoin) in Participants With Long-Chain Fatty Acid Oxidation Disorders (LC-FAOD) (NCT NCT01886378)

NCT ID: NCT01886378

Last Updated: 2021-02-11

Results Overview

To evaluate the impact 24 weeks of treatment with UX007 has on exercise intolerance, the change from Baseline in time adjusted-AUC (AUC/time) for workload during 40-minute cycle ergometry tests at Week 24 were assessed using the generalized estimation equation (GEE) model. A cycle ergometer can measure the work performed by an individual over time during physical exercise, the work was measured every 10 minutes from 0 to 40 minutes at Baseline and Week 24. The GEE model included the change from Baseline as the dependent variable, time as the categorical variable, and adjusted for Baseline measurement with compound symmetry covariance structure. An increase in AUC is reflective of improved exercise tolerance; a negative change from Baseline indicates worsening.

Participant Flow

Following the signing of informed consent at the Screening visit, each participant continued on current long-chain fatty acid oxidation disorder (LC-FAOD) management for a 4-week Run-in Period to establish a clinical baseline. Following completion of the 4-week Run-in Period, participants discontinued any use of medium chain triglycerides (MCT) and began treatment with UX007.

Change from baseline in time-adjusted-AUC for respiratory exchange ratio (RER) during cycle ergometry at Week 24, assessed using the GEE model, which included change from baseline as dependent variable, time as categorical variable, and adjusted for baseline measurement with compound symmetry covariance structure. RER during exercise is calculated as volume of carbon dioxide/volume of oxygen. RER measures whether carbohydrates or fats are being used as fuel. RER ≥1.0 indicates carbohydrates are the predominate fuel source. RER \<1.0 and RER \>0.70 indicates both fats and carbohydrates are the predominate fuel source. RER approximately =0.70 means fat is the predominant fuel source. RER would be expected to be lower, at similar exercise intensities, if a participant is able to utilize fat as an energy source. Therefore, an increase in RER (positive change from baseline) would suggest participants are still utilizing carbohydrates rather than fat, reflective a physiological response.

To evaluate the impact of 24 weeks of treatment with UX007 on exercise intolerance, the change from Baseline in actual duration of exercise during 40-minute cycle ergometry tests at Week 24 was assessed using the GEE model. The GEE model included the change from Baseline as the dependent variable, time as the categorical variable, and adjusted for Baseline measurement with compound symmetry covariance structure. Duration of exercise is expected to increase as exercise tolerance improves.

To evaluate the impact 18 weeks of treatment with UX007 has on muscle function, the change from Baseline in distance traveled during a 12MWT at Week 18 was assessed using the GEE model. The GEE model included the change from Baseline as the dependent variable, time as the categorical variable, and adjusted for Baseline measurement with compound symmetry covariance structure. Distance traveled during the 12MWT is expected to increase as muscle function increases.

To evaluate the impact 18 weeks of treatment with UX007 has on muscle function, the change from Baseline of EEI during the 12MWT at Week 18 was assessed using the GEE model. The GEE model included the change from Baseline as the dependent variable, time as the categorical variable, and adjusted for Baseline measurement with compound symmetry covariance structure. EEI is quantified as the post-test heart rate minus the pre-test heart rate (in beats/min) divided by overall velocity, and is valued in beats/meter. A decrease in EEI when walking a similar distance or no change when walking longer distances, may indicate improved exercise tolerance.

Population: Primary Analysis Set - 12MWT: the subset of participants in the primary analysis set (all enrolled participants who completed the 4 week Run-in Period and received at least one dose of UX007) who had at least one 12MWT performed with any distance walked.

To evaluate the impact 18 weeks of treatment with UX007 has on muscle function, the change from Baseline in the percentage of the predicted distance traveled during the first 6 minutes (6MWT) of the 12MWT at Week 18 was assessed using the GEE model. A participant's mathematical formula to calculate their percent predicted (PP) distance walked in the 6MWT was based on their demographics at baseline. For participants \< 20 years old, the formula used was referenced from (Gieger, et. al. 2007) which calculated PP distance walked based on age, gender, and height. For participants \>= 20 years old, the formula used was referenced from (Gibbons, et. al. 2001) and calculated the PP distance walked based on age and gender. The GEE model included the change from Baseline as the dependent variable, time as the categorical variable, and adjusted for Baseline measurement with compound symmetry covariance structure. Percent predicted values are expected to increase as muscle function increases.

To evaluate the impact treatment with UX007 has on functional disability and health in participants between 5 and 17 years of age, change from Baseline in the T-scores of the PHS-10 were assessed at Week 24 and analyzed using the GEE model. The GEE model included the change from Baseline as the dependent variable, time as the categorical variable, and adjusted for Baseline measurement with compound symmetry covariance structure. The SF-10 Health Survey for Children is a 10-item caregiver-completed assessment designed to measure children's health-related quality of life. The PHS-10 of the SF-10 is scored such that higher scores indicate more favorable functioning. The T-score based scoring signifies that scale scores are centered so that a score of 50 corresponds to the average score in a comprehensive sample of US population (scale scores are standardized to a mean of 50 and a standard deviation of 10).
