JRCT ID: jRCT2051190094

Registered date:15/01/2020

Basic Information

• Recruitment status: Complete
• Health condition(s) or Problem(s) studied: Insulin resistance syndrome (type A, type B, type non-A non-B), Lipoatrophic diabetes mellitus
• Date of first enrollment: 26/03/2020
• Target sample size: 8
• Study type: Interventional

Intervention(s)

The study treatment shall be started from the next day of the Week 24 visit of the EMPIRE-01 study after enrollment. The investigational drug shall be administered at the same dosage as that of the empagliflozin tablet administered from Week 12 to Week 24 of the treatment period in the EMPIRE-01 study.
The administration is oral administration with water once daily before or after breakfast.

Outcome(s)

• Primary Outcome: Presence/absence of adverse events, adverse drug reactions, and use of rescue treatment drugs until Week 28 (Week 52 of the EMPIRE-01 study)

Secondary Outcome

(1)HbA1c change rate at Week 28 (52) of the treatment from baseline The HbA1c change rate at Week 28 (52) from baseline is defined as HbA1c change from baseline divided by baseline HbA1c of the EMPIRE-01 study and multiplied by 100.
(2)HbA1c change at Week 28 (52) of the treatment from baseline
The HbA1c change at Week 28 (52) of the treatment from baseline is defined as the difference in HbA1c levels between Week 28 (52) and baseline of the EMPIRE-01 study.
(3)HbA1c at each time point
The HbA1c at each time point is defined as the HbA1c levels at baseline of the EMPIRE-01 study, Week 12 (36), Week 28 (52), or at discontinuation.
(4)Fasting plasma glucose (FPG) at each time point
The FPG at each time point is defined as the FPG levels at baseline of the EMPIRE-01 study, Week 12 (36), Week 28 (52), or at discontinuation.
(5)Fasting plasma glucose (FPG) change at Week 28 (52) of the treatment from baseline
The FPG change at Week 28 (52) of the treatment from baseline is defined as the difference in the FPG levels between Week 28 (52) and baseline of the EMPIRE-01 study.
(6)Insulin dose at each time point (TDD, TBD)
The TDD and TBD at each time point are defined as the insulin doses at baseline of the EMPIRE-01 study, Week 12 (36), Week 28 (52), or at discontinuation.
(7)Postprandial glucose for 2 hours over time
Postprandial glucose for 2 hours shall be measured for 14 days starting from Week 12 (36) by using FreeStyle Libre ProTM.
