Reporting Groups

	Description
Group A (P1 SYMLIN)	SYMLIN treatment (120 mcg prior to major meals) was initiated on Day 1. Basal insulin was titrated throughout the study
Group B (P1 RA Insulin)	Rapid acting insulin (RA Insulin: variable dosing, titrated to optimize postprandial glucose control) was initiated at Week 4. Basal insulin was titrated throughout the study
Group C (P2 SYMLIN)	Patients from Group A, who achieved HbA1c goal at Week 24, continued Phase 1 treatment during Phase 2
Group D (P2 SYMLIN+RA)	Patients from Group A, who did not achieve HbA1c goal at Week 24, continued phase 1 treatment and initiated RA insulin during Phase 2
Group E (P2 RA Insulin)	Patients from Group B, who achieved HbA1c goal at Week 24, continued Phase 1 treatment during Phase 2
Group F (P2 RA Insulin + SYMLIN)	Patients from Group B, who did not achieve HbA1c goal at Week 24, continued phase 1 treatment and initiated SYMLIN during Phase 2
