Start is estimated for Apr 2027; primary completion for Oct 2028, 18 months later.
Of 470 non-industry interventional studies with no phase under Alcoholism, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 55. This study's planned 18 months is below that.
Counting every sponsor, half of 493 studies reached it within 33 months; a quarter within 17 and three quarters within 53.
