February 14, 2022 updated by: Michael Tsoukas

A Randomized Controlled Pilot Study to Assess the Pharmacokinetics, Pharmacodynamics, and Closed-loop Efficacy of BC LisPram Compared to Rapid Insulin in Pump-treated Adults With Type 1 Diabetes

This pilot study is a 50-hour randomized, open-label, crossover study in an inpatient setting assessing the safety, pharmacodynamics, pharmacokinetics, and closed-loop efficacy of i) BC LisPram delivery and ii) rapid insulin delivery.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Subjects will be randomized to intervention sequences. The first 6 participants will be randomly allocated to a sequence of three treatments composed of (i) treatment with active comparator insulin lispro, (ii) treatment with BC LisPram, and (iii) treatment with BC LisPram (dual wave bolus). The following 10 participants will be randomly allocated to a sequence of either two or three treatments. Each treatment period will last 50 hours. PK/PD assessment will be performed under an open-loop system and will be followed by a 24 hour of closed-loop assessment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Males and females ≥ 18 years of age.
  • Clinical diagnosis of type 1 diabetes for at least 12 months. The diagnosis of type 1 diabetes is based on the investigator's judgment; C peptide level and antibody determinations are not needed.
  • Insulin pump therapy for at least 3 months, with daily insulin needs ranging between 30 and 80 U.
  • Most recent HbA1c ≤ 9.5% (over the last two months).
  • Effective birth control in female participants of childbearing potential. Medically acceptable contraception methods include condom, pills, and intrauterine device.

Exclusion Criteria:

  • Current or ≤ 1 month use of other antihyperglycemic agents (SGLT2, GLP-1, Metformin, Acarbose, etc....).
  • Current use of glucocorticoid medication.
  • Use of medication that alters gastrointestinal motility.
  • Planned or ongoing pregnancy.
  • Breastfeeding individuals
  • Severe hypoglycemic episode within one month of admission.
  • Severe diabetic ketoacidosis episode within one month of admission.
  • Clinically significant nephropathy, neuropathy or retinopathy as judged by the investigator.
  • Recent (< 6 months) acute macrovascular event e.g. acute coronary syndrome or cardiac surgery.
  • Known hypersensitivity to any of the study drugs or their excipients.
  • Allergy to paracetamol (acetaminophen).
  • Other serious medical illness likely to interfere with study participation or with the ability to complete the trial by the judgment of the investigator.
  • Clinically abnormal significant values for haemato, biochemistry, or urinalysis screening test as judged by the Principle Investigator for underlying disease.
  • Failure to comply with team's recommendations (e.g. not willing to eat meals/snacks, not willing to change pump parameters, etc.).
