Who cannot join

  • Pregnant, lactating or intending to become pregnant during the study.
  • Subjects with confirmed diabetes type 1 or type 2.
  • Presence of any clinically significant co-morbidities, or physical exam, ECG, or laboratory findings at screening or upon clinic admission that, in the opinion of the Investigator, may interfere with any aspect of study conduct or interpretation of the study results.

About this study

Official title: A Randomized, Double-Blind, Cross Over Study to Assess Pharmacokinetic and Pharmacodynamic Effects of Insulex® R in Comparison to Humulin® R in Healthy Subjects

The goal of this clinical trial is to evaluate whether Insulex® R demonstrates similar pharmacokinetic (PK) and pharmacodynamic (PD) profiles compared to Humulin® R after a single subcutaneous dose of 0.3 units/kg in healthy adult volunteers.

Read the detailed description

This Phase 1, randomized, double-blind, two-period, two-sequence crossover clinical trial aims to evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) bioequivalence of Insulex® R compared to Humulin® R after a single subcutaneous dose of 0.3 units/kg in healthy adult subjects. The study was designed in accordance with international regulatory guidelines, including the U.S. Food and Drug Administration (FDA) guidance for demonstrating biosimilarity of insulin products and the European Medicines Agency (EMA) guidelines for the clinical development of biosimilar insulins. Each subject underwent a Screening Visit (Visit 1), two 1-day in-house Treatment Periods (Visit 2 and Visit 3), and a Follow-up Visit (Visit 4) to performed safety procedures. The washout period between Treatment Periods was 7 to 14 days. During each Treatment Period, subjects will receive a single subcutaneous dose of either Insulex® R or Humulin® R under euglycemic glucose clamp conditions. Blood samples will be collected at prespecified intervals to measure serum insulin and C-peptide concentrations. Glucose infusion rates will be monitored continuously to assess PD response. The rigorous assessment of PK and PD profiles under controlled clamp conditions is essential to confirm biosimilarity and ensure therapeutic equivalence. Successful demonstration of bioequivalence will provide a safe, effective, and cost-accessible recombinant human rapid-acting insulin option for patients requiring insulin therapy.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Insulex® R (soluble human insulin, biosimilar) and Humulin® R (soluble human insulin, biosimilar) in people with Healthy Subjects, run by Laboratorios Pisa S.A. de C.V. 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 5 inclusion and 19 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 23 Jan 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 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?

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?

AUCINS_0-12h (time frame: 12 hours). 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?

On the ClinicalTrials.gov record for NCT07364669, which also lists 7 linked publications.

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 23 Jan 2026.
