About this study

Official title: Ready-to-use Dasiglucagon for the Treatment of Postprandial Hypoglycaemia in Roux-en-Y Gastric Bypass Operated Patients

This is an investigator-initiated, proof-of-concept, randomised, double-blind, placebo-controlled, single-centre phase II study aiming to evaluate the efficacy, safety and tolerability of self-administered subcutaneous 120 µg dasiglucagon with an investigational trial device (i.e. a multi-dose reusable pen) for the treatment of postprandial hypoglycaemia after Roux-en-Y gastric bypass (RYGB) surgery. The study is divided into an in-patient and out-patient part.

The primary aim of the study is to compare the effects of self-administered 120 µg dasiglucagon versus placebo on continuous glucose monitoring (CGM)-assessed time spent in hypoglycaemia in RYGB-operated individuals in an out-patient setting.

Read the detailed description

Study design:

Before inclusion in the study, the participants will complete a screening visit and a blinded 14-day continuous glucose monitoring (CGM) run-in period to ascertain a regular occurrence of postprandial hypoglycaemia (IG <3.9 mmol/l, ≥3 times/week). After enrolment in the study, the participants will wear a CGM for the entirety of the study period (apart from the four weeks before the follow-up visit). Prior to the first mixed meal test (MMT) during the in-patient part, the subjects will be randomised into one of four double-blinded treatment sequences consisting of an in-patient part (two MMTs) follow by a nine weeks out-patient part (two times four weeks per out-patient part with an interposed washout period of one week) and ended with a follow-up visit four weeks after out-patient part completion.

During the in-patient part, the participants will undergo two separate MMTs, with a minimum of 7 days in-between, accompanied by one of the following double-blind, randomised, placebo-controlled crossover interventions:

  1. Subcutaneous placebo self-administration
  2. Subcutaneous 120 µg dasiglucagon self-administration

The out-patient part is divided into two double-blinded, randomised, placebo-controlled crossover out-patient parts with of the following interventions:

  1. Subcutaneous placebo self-administration
  2. Subcutaneous 120 µg dasiglucagon self-administration

Dasiglucagon, HyoPen, Placebo

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Dasiglucagon and HyoPen in people with Hyperinsulinemic Hypoglycemia and Postprandial Hypoglycemia, run by Filip Krag Knop at 1 site in Denmark.

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 13 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 2 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Time spent in hypoglycaemia (IG < 3.9 mmol) (time frame: During the four weeks of placebo and dasiglucagon treatment.). 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 2 Feb 2023.
