RT001 is encapsulated 9-cis, 12-cis-11,11-D2-linoleic acid ethyl ester, which is a site specific (C11) di-deutero synthetic homologue of LA ethyl ester. Each capsule contains 960 mg of RT001.
Placebo Comparator: Placebo
The placebo product is composed of encapsulated USP safflower oil. The placebo capsules are identical in appearance and size to RT001.
- Peak workload change from baseline to 11 months using cardiopulmonary exercise testing (CPET) [ Time Frame: 11 months ]To measure the percentage change in peak workload from baseline to Month 11 using CPET
- Effect of RT001 on modified Friedreich Ataxia Rating Scale (mFARS) [ Time Frame: 11 months ]The modified FARS is derived from the FARS Neuro Scale. The FARS Neuro Scale is based on the neurological examination of the Bulbar System, Upper Limb Coordination, Lower Limb Coordination, Peripheral Nervous System and Upright Stability Function. The mFARS will not include sub-scores from Peripheral Nervous System.
- Distance walked during a 1-minute walk (T1MW) [ Time Frame: 11 months ]The T1MW is a quantitative measure of lower extremity function. The distance walked over 1 minute is measured
- Effects of RT001 on a Fatigue scale [ Time Frame: 11 months ]To measure the change in score from baseline to Month 11 on a fatigue scale. This scale rates your fatigue over the last 7 days and is rated on a 5 point scale with a range of responses from not at all, a little bit, some what, quite a bit and very much.
- Effects of RT001 on Clinical Global Impression [CGI] [ Time Frame: 11 months ]The CGI is a 3-item observer rated scale that measures illness severity, global improvement and therapeutic response.The illness severity is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through 7 (amongst the most severely ill patients). The global improvement scores range from 1 (very much improved) through to 7 (very much worse). Treatment response ratings should take account of both therapeutic efficacy and treatment-related adverse events and range from 0 (marked improvement and no side-effects) and 4 (unchanged or worse and side-effects outweigh the therapeutic effects). Each component of the CGI is rated separately; the instrument does not yield a global score.
