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

The Investigational Medical Device (IMD) for this investigation is the Prototype 0.5 (P0.5) developed and manufactured by RSP Systems (RSP). The device is intended for non-invasive interstitial intermittent glucose monitoring in persons (age 18 and older) with diabetes. The technology relies on the well-established capacities of Raman spectroscopy for directly detecting glucose subcutaneously. The Raman spectroscopy physical principle relies on the fact that when laser light of a given wavelength interferes with a molecule, a small fraction of the incident light will interact with the vibrational states of the molecule, causing the photons to lose a portion of their energy which will change the wavelength of the light. The scattered light will be collected by the optical probe head and analyzed with advanced algorithms to correlate the signal to glucose concentrations. Data collected from the IMD will be paired with validated glucose reference values collected by the finger sticking method.

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

1 year and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

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.

Measure Description
Time Frame
Measurement accuracy
