Sequence 1:Arm Region,Abdomen 6mm,Buttock,Abdomen 9mm,ThighExperimentalParticipants had cannulas inserted into each of the designated infusion sites (6 millimeter (mm) for all the sites. Additionally for the abdominal area only, a 9 mm cannula was also inserted into the opposite side of the lower abdomen), and the first infusion site was initiated subcutaneously (SC) with 15 millimolar (mM) sodium citrate and 1 microgram per milliliter (μg/mL) treprostinil in Humalog diluent with 5 mM magnesium chloride (without insulin) solution at a basal infusion rate of 1 unit per hour (U/h). The same procedure occurred at subsequent infusion sites with an approximately 30-minute (min) interval between each initiation. Approximately 3, 6, and 9 hours after the start of the basal infusion, a bolus dose of 15 U was delivered at quick bolus speed (15 U/min) to each infusion site according to the treatment sequence with an approximately 30-minute interval between infusion sites.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual Analog Scale (VAS) Pain Score in the Abdominal, Arm, Thigh, and Buttock Areas

    The Infusion site pain VAS score is a participant administered single item scale designed to measure pain using a 0-100 millimeter (mm) horizontal VAS. Overall severity of participant's pain is indicated by placing a single mark on the horizontal 100 mm scale from 0 mm (no pain) to 100 mm (worst imaginable pain).

    Measured: Day 1: 1 min post bolus.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Sodium Citrate, Treprostinil and Humalog diluent in people with Type 1 Diabetes Mellitus, run by Eli Lilly and Company at 2 sites in Germany.

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 6 inclusion and 9 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 4 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Germany. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 4 Oct 2023). 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?

Visual Analog Scale (VAS) Pain Score in the Abdominal, Arm, Thigh, and Buttock Areas (time frame: Day 1: 1 min post bolus.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05067270, which also lists 1 linked publication.

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 4 Oct 2023.
