Arms Assigned Interventions
Experimental: before meal group
ASP1941 will be administered before meal
Drug: ASP1941
Experimental: after meal group
ASP1941 will be administered after meal
Drug: ASP1941

Detailed Description:

Subject will be randomized into either ASP1941 before meal or ASP1941 after meal groups. Subjects will undergo a screening period before entering the long-term treatment. Dosage may be increased during the treatment period if subjects fulfill increasing criteria and the investigators adjudicate that no impact for subjects safety.
