A Study of ASP1941 in Combination With Insulin in Patients With Type 1 Diabetes Mellitus

March 5, 2019 updated by: Astellas Pharma Inc

Phase III Study of ASP1941 Double-blind, Parallel-group Study in Combination With Insulin in Patients With Type 1 Diabetes Mellitus

The objective of this study is to confirm efficacy of ASP1941 based on the changes in HbA1c and to assess its safety in subjects with type 1 diabetes mellitus receiving ASP1941 once daily in combination with insulin for 24 weeks. This study will also assess the safety/efficacy of long-term treatment (52 weeks).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study consists of two parts. In Part 1, ASP1941 or placebo will be administered orally in a blind manner. In Part 2, the long-term safety and efficacy of ASP1941 will be evaluated in patients who have participated in the study and completed the Part 1.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
