A Phase IIb, Randomized, Multi-Center, Multinational, Prospective, Double-Blind, Placebo-Controlled Study, With an Open Label Extension, to Evaluate Safety, Tolerability and Efficacy of PrimeC in Subjects With ALS
Study Purpose:
69 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).
