Cómo lo describe el promotor

En el documentoEn inglés, del registro69 subjects with ALS will be enrolled in the study and randomized at a 2:1 ratio to receive the study drug or placebo tablets. Randomization sequences will be in random block sizes and stratified for ENCALS risk category \[high risk ≥ -4.5 vs. low risk \< -4.5\], and for background ALS treatment (riluzole and/or edaravone and/or sodium phenylbutyrate and/or taurursodiol) vs. no background ALS treatment. All subjects will be administered the drug/placebo twice daily (BID), two tablets each time, for 6 months. Subjects will be allowed to receive standard of care (SOC) treatment of approved products (i.e., riluzole and edaravone). Additionally, subjects will be allowed to receive treatment with off-label sodium phenylbutyrate and taurursodiol, which are accepted for ALS treatment. Subjects will be evaluated every 2 months for safety, tolerability (adverse events, safety laboratory, vital signs, ECG, withdrawal rates and reasons) and efficacy (e.g. biomarkers, clinical outcomes (ALSFRS-R and SVC, quality of life and survival). All subjects who complete the 6 months dosing will be switched to the active arm for a 12-month open label extension (OLE).
