Ran from Feb 2026 to primary completion in May 2026, 2 months.
Of 87 industry-sponsored interventional studies with no phase under Presbyopia, half reached primary completion within 6 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 19. This study's 2 months is below that.
Counting every sponsor, half of 129 studies reached it within 10 months; a quarter within 3 and three quarters within 23.
