What is being measured

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

  1. Maximum Serum Insulin Aspart Concentration, CIAmax

    Pharmacokinetic (PK) blood samples will be collected from 60 minutes before dose through 12 hours post-dose. Serum will be isolated for analyzing the concentrations of Insulin Aspart

    Measured: Baseline (Time 0) to 12 hours post-dose

  2. Area Under the Curve (AUC) of Insulin Aspart Serum Concentration From Time 0 to 12 Hours Post-dose, AUCIA(0-12h)

    Pharmacokinetic (PK) blood samples will be collected from 60 minutes before dose through 12 hours post-dose. Serum will be isolated for analyzing the concentrations of Insulin Aspart. AUCIA(0-12h) will be calculated from the concentration curves. Only AUC from 0 to 12 hours (AUCIA(0-12h)) is reported.

    Measured: 0 to 12 hours post-dose

  3. Maximum Glucose Infusion Rate, Gmax

    Participants will undergo a euglycemic clamp, where blood glucose concentration will be held at a constant target level by adjusting exogenous glucose infusion rate (GIR) following drug administration. GIR will be recorded for the duration of the euglycemic clamp and used to evaluate the Pharmacodynamic (PD) response.

    Measured: From drug administration to 12 hours post-dose

  4. Area Under the Curve (AUC) for Glucose Infusion Rate From Time 0 to 12 Hours Post-dose, AUCG(0-12h)

    Participants will undergo a euglycemic clamp, where blood glucose concentration will be held at a constant target level by adjusting exogenous glucose infusion rate (GIR) following drug administration. GIR will be recorded for the duration of the euglycemic clamp and used to evaluate the Pharmacodynamic (PD) response. AUCG(0-12h) will be calculated from the glucose infusion rate curves. Because GIR is recorded in mg/kg/min, the area under the GIR-time curve has units mg/kg.

    Measured: From drug administration to 12 hours post-dose

Secondary outcomes (19)
  1. Area Under the Curve (AUC) of Insulin Aspart Serum Concentration From Time 0 to Infinity, AUCIA(0-∞)

    Pharmacokinetic (PK) blood samples will be collected starting 60 minutes before dose through 12 hours post-dose. Serum will be isolated for analyzing the concentrations of Insulin Aspart. AUCIA(0-∞) will be calculated from the concentration curves. AUCIA(0-∞) is derived using standard extrapolation beyond the last measurable concentration.

    Measured: 0 to infinity (extrapolated; concentrations measured through 12 hours post-dose)

  2. Area Under the Curve (AUC) of Insulin Aspart Serum Concentration From Time 0 to 2 Hours Post-dose, AUCIA(0-2h)

    Pharmacokinetic (PK) blood samples will be collected starting 60 minutes before dose through 12 hours post-dose. Serum will be isolated for analyzing the concentrations of Insulin Aspart.

  7. Maximum Serum Human Insulin Concentration, CHImax

    Pharmacokinetic (PK) blood samples will be collected starting 60 minutes before dose through 12 hours post-dose. Serum will be isolated for analyzing the concentrations of Human Insulin.

    Measured: Baseline (Time 0) to 12 hours post-dose

  8. Area Under the Curve (AUC) of Human Insulin Serum Concentration From Time 0 to 12 hours post-dose, AUCHI(0-12h)

    Pharmacokinetic (PK) blood samples will be collected starting 60 minutes before dose through 12 hours post-dose. Serum will be isolated for analyzing the concentrations of Human Insulin.

    Measured: Baseline (Time 0) to 12 hours post-dose

  9. Time of Maximum Human Insulin Serum Concentration, tHImax

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing I004 and NovoLog in people with Pharmacokinetics and Pharmacodynamics, run by Amphastar Pharmaceuticals, Inc. at 1 site in United States.

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 8 inclusion and 21 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 22 Jul 2026. 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 United States. 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 combined 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.

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?

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?

Maximum Serum Insulin Aspart Concentration, CIAmax (time frame: Baseline (Time 0) to 12 hours post-dose). The study lists 4 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 22 Jul 2026.
