About this study

Official title: A Clinical Pharmacology and Long Term Study to Evaluate the Safety, Efficacy, Pharmacokinetics and Pharmacodynamics of Dapagliflozin Therapy in Combination With Insulin in Japanese Subjects With Type 1 Diabetes Who Have Inadequate Glycemic Control

This study will enroll eligible subjects into a long-term safety study (Part B).

Japanese male and female patients with T1DM and age 18 to 75 years, with inadequate glycemic control on insulin defined as HbA1c ≥ 7.5% and ≤ 10.5% at screening visit. As a condition of enrollment, subjects must be on a total daily insulin dose of ≥ 0.3 U/kg/day for at least 3 months prior to the screening visit. The study design of Part B is a randomized, open-label, 2 arm, parallel-group design. 140 Japanese subjects in total will be randomized in a 1:1 ratio into one of the two treatment arms; dapagliflozin 5 mg or dapagliflozin 10 mg.

Being tested

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dapagliflozin 5 mg and Dapagliflozin 10mg in people with Type 1 Diabetes Mellitus, run by AstraZeneca at 24 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Apr 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Adverse Event Summary (time frame: From baseline to 52 weeks). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Apr 2019.
