Eksperimentel: Cadisegliatin 800 mg QD: Double Blind, Randomized Crossover Trial Design
If a patient is randomized to receive cadisegliatin 800 mg QD as an adjunctive therapy to their insulin treatment in the first double-blind treatment period of 6 weeks, there will then be a washout period of 1-2 weeks followed by the second double-blind treatment period of 6 weeks where the patient will cross-over to the placebo QD along with their insulin treatment arm

Placebo komparator: Placebo: Double Blind, Randomized Crossover Trial Design
If a patient is randomized to receive placebo QD along with their insulin treatment in the first double-blind treatment period of 6 weeks, there will then be a washout period of 1-2 weeks followed by the second double-blind treatment period of 6 weeks where the patient will cross-over to the cadisegliatin 800 mg QD as an adjunctive therapy to their insulin treatment arm
