Study Endpoints

Primary Endpoints

Visual Analog Scale (VAS) Pain Score in the Abdominal, Arm, Thigh, and Buttock Areas
Day 1: 1 min post bolus.

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).

Number of Participants With One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration
Part A: Baseline through Study Completion (up to 14 Days after Last Dose)

A summary of SAEs and other non-serious adverse events (AEs), regardless of causality, are reported in the Adverse Events module.

Treatment Arms

ArmTypeDescription
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.
Sequence 2:Abdomen 6mm,Abdomen 9mm,Arm Region,Thigh,ButtockEXPERIMENTALParticipants had cannulas inserted into each of the designated infusion sites (6 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 with 15 mM sodium citrate and 1 μg/mL treprostinil in Humalog diluent with 5 mM magnesium chloride (without insulin) solution at a basal infusion rate of 1 U/h. The same procedure occurred at subsequent infusion sites with an approximately 30-minute 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.
Sequence 3:Abdomen 9mm,Thigh,Abdomen 6mm,Buttock,Arm RegionEXPERIMENTALParticipants had cannulas inserted into each of the designated infusion sites (6 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 with 15 mM sodium citrate and 1 μg/mL treprostinil in Humalog diluent with 5 mM magnesium chloride (without insulin) solution at a basal infusion rate of 1 U/h. The same procedure occurred at subsequent infusion sites with an approximately 30-minute interval between each initiation.

Sequence 4:Thigh,Buttock,Abdomen 9mm,Arm Region,Abdomen 6mmEXPERIMENTALParticipants had cannulas inserted into each of the designated infusion sites (6 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 with 15 mM sodium citrate and 1 μg/mL treprostinil in Humalog diluent with 5 mM magnesium chloride (without insulin) solution at a basal infusion rate of 1 units per U/h.

Frequently asked questions about Treprostinil

What is Treprostinil used for?

Treprostinil is an investigational small molecule being studied in healthy volunteers and in people with Type 1 Diabetes Mellitus. In clinical trials, it has been evaluated for its effects when given alongside other investigational products. It is not approved and remains in early-stage clinical development.

Who makes Treprostinil?

Treprostinil is being developed by Eli Lilly and Company, a biopharmaceutical company traded on the NYSE under the ticker LLY. The company is conducting Phase 1 clinical trials with this investigational small molecule.

What phase is Treprostinil in?

Treprostinil is in Phase 1 clinical development. Two Phase 1 studies have been completed, one in healthy participants and one in participants with Type 1 Diabetes Mellitus. The drug is investigational and has not been approved by regulatory authorities.

What clinical trials is Treprostinil in?

Treprostinil has been studied in two completed Phase 1 trials. NCT02770521 enrolled 23 healthy Japanese participants, and NCT05067270 enrolled 40 participants with Type 1 Diabetes Mellitus. Both trials were randomized, double-blind, and placebo-controlled.

Is Treprostinil the same as LY900014?

Treprostinil is not the same as LY900014. In one clinical trial, NCT02770521, treprostinil was studied alongside a new formulation of LY900014, an investigational product from the same developer. They are separate agents evaluated in the same study.
