Study Arms (3)
Cadisegliatin: 26 Week Double Blind Treatment Period - 800 mg QD
EXPERIMENTALThe main study uses a randomized, double-blind, placebo-controlled design with parallel assignment among 3 treatment arms. The trial begins with a screening period of up to 14 days, followed by a 28-day device training and insulin adjustment period leading into a 28-day baseline period before entering the 26-week treatment period. Insulin is adjunctive therapy.
