About this study

Official title: Clinical Performance of Masimo INVSENSOR00048

This clinical study is to validate temperature performance of the noninvasive Masimo INVSENSOR00048.

Conditions: Temperature
Being tested: INVSENSOR00048

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

INVSENSOR00048Device
Noninvasive sensor will be attached to the subjects' skin with a medical grade biodegradable /adhesive, approximately 2 inches below the left clavicle to measure temperature

Study groups in NCT06922461
Study group	Role	What they receive
INVSENSOR00048	Experimental	All subjects are enrolled into the test group and are fitted with the non-invasive investigational sensor for body temperature measurements Receives: Device: INVSENSOR00048

What is being measured

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

Primary Outcome
The determination of the Masimo INVSENSOR00048 temperature performance by comparing the Clinical Bias and Limits of Agreement (LOA) between the corresponding adjustment mode temperature of the device under test (DUT) and reference thermometer. Clincal Bias is defined as mean difference between output temperatires of a clinical thermometer and a reference clinical thermometer for the intended reference body site with specified limitis of agreement when measured from selected group of subjects . Limits of agreement is defined as the magnitude of a potential disagreement between outputs of two clinical thermometers equal to double the standard deviation of output temperate differences when used on the same human subject .
Measured: Approximately 90 minutes

Time frame: Approximately 90 minutes. Number. Unit: Degrees Celsius

Measure	INVSENSOR00048 n = 1
Clinical Bias	0.18
Limits of Agreement	0.80

Population analysed: The study was terminated early and the sample size was insufficient to statistically compare data collected to the reference values. Hence, the clinical performance of the Masimo INVSENSOR00048 could not be computed. Subjects were excluded from analysis due toa lack of a minimum of three (3) reference measurement groups , data that suggests a defective device or sensor , or data that suggests the existence of external conditions that interfere with DUT measurements or reference measurements

Adverse events

Time frame: At a single visit for approximately 1 to 5 hours. Other adverse events reported at 0% frequency or more

Group	Serious adverse events	Other adverse events	Deaths
INVSENSOR00048	0 of 4 (0%)	0 of 4 (0%)	0 of 4

Limitations and caveats (from the sponsor): The study was terminated early and the sample size was insufficient to statistically compare data collected to the reference values. Hence, the clinical performance of the Masimo INVSENSOR00048 could not be computed.

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.

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?

Primary Outcome (time frame: Approximately 90 minutes). 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 NCT06922461.
