Safety and Performance of the Glyconics-SX System (ANODE02) (ANODE02)

November 2, 2022 updated by: Glyconics Ltd

A Single-Centre, Open-label Study Testing the Safety and Performance of the Glyconics-SX System in Individuals With or Without Type 2 Diabetes

The main clinical study objective is to retrieve initial high quality spectra measurements indicative of the accuracy of the Glyconics-SX System in distinguishing between individuals with or without T2DM based on known and/or assumed clinical status and as controlled by values of an internal biomarker indicative of glycaemia, HbA1c, as measured with a validated comparator device.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Apparently healthy adults (≥18 years of age) with known or unknown T2DM status willing to participate in and provide a written consent for the study
  • willingness to undertake assisted assessment of glycaemia by both the NIR spectra measurement, and HbA1c by finger prick test
  • Individuals with two visually assessed apparently healthy, undamaged, and intact fingernails, one in both right- and left-hand middle fingers

Exclusion Criteria:

Individuals with any known medical conditions impacting either of the assessment methodology for glycaemia, such as

  • anaemia (iron deficiency sickle cell anaemia or similar)
  • haemoglobinopathies or atypical haemoglobin subtypes not detectable by regular assays,
  • severe renal impairment (CKD stage III-IV) or decompensated hepatic disease
  • severe Vitamin D deficiency
  • known severe immunodeficiency such as HIV, malignancy or other chronic condition significantly impacting assessment of glycaemia
  • eating disorders (as per clinical assessment)

  • Recent (within 28 days) blood donation

    o Any structural, deviating and visually detectable deviations in the appearance of the nails potentially impacting the spectra measurement, including

  • nail dystrophy or deformity
  • severe nail infections (onychomycosis causing visual changes in the appearance of the nail)
  • rare hereditable conditions impacting the structure of keratin
  • mechanical damage or marks on the surface of the nail after removal of nail polish
  • use of acrylic or gel nail decoration and polish, which cannot be removed o Any systemic or topical medication known to modify either the surface or structure of the nail or accuracy of HbA1c value.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Accuracy of the Glyconics-SX System in detection of DM status based on dichotomised outcomes as per the chemometric model (HbA1c measurements as internal control)
Time Frame: 60 seconds
Overall probability of correct classification by the chemometric model output (yes / no DM)
60 seconds

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assessment of sensitivity and specificity for chemometric model outcomes
Time Frame: 60 seconds
False positive and false negative assessments in %
60 seconds
Calculation of negative and positive predictive value for the chemometric model
