Characterization of Pre-Term Neonatal Skin
A study testing Diffuse Reflectance Spectroscopy and BiliChek in people with Skin Disorder, run by University of Arkansas at 1 site in United States.
Trial summary
The skin of pre-term neonates is not fully developed and often leads to trans-epidermal water loss, trouble regulating temperature, and increased risk of skin wounds. Current treatment decisions are based on subjective, qualitative assessments of the skin. Read more about this study

About this study
Official title: Characterization of Pre-Term Neonatal Skin by Diffuse Reflectance Spectroscopy Pilot Study
The skin of pre-term neonates is not fully developed and often leads to trans-epidermal water loss, trouble regulating temperature, and increased risk of skin wounds. Current treatment decisions are based on subjective, qualitative assessments of the skin. The purpose of this pilot study is to evaluate the utility of non-invasive optical spectroscopy methods to collect key biological information from neonatal skin, including skin maturity, blood oxygenation, and bilirubin content. Parents of pre-term neonatal subjects (n=44) will be recruited for consent to participate, and spectral measurements will be made with a diffuse reflectance spectrometer(DRS) device previously approved by the University of Arkansas for Medical Sciences Institutional Review Board. The spectral data will be analyzed to extract parameters related to tissue light scattering, oxy-and deoxy-hemoglobin, melanin, and bilirubin. The system will be validated by comparing extracted spectra with expected literature values and directly correlating the measured bilirubin levels with readouts from the current University of Arkansas for Medical Sciences practice standard: Philip's BiliChek. The long-term goal is to develop and use non-invasive optical readouts to predict and monitor skin dysfunction in the Neonatal Intensive Care Unit (NICU).
Read the detailed description
This is a cross-sectional, pilot study to characterize the response of neonatal premature skin to DRS when excited with a white light source, and provide a baseline of how the collected spectra change with the maturation of the epidermal layer in the weeks to term gestation after birth. DRS spectra and BiliChek measurements will be performed on the study population admitted to the Neonatal Intensive Care Unit. The pilot data will be used to evaluate whether Diffuse Reflectance Spectroscopy spectra can be used to extract optical information on skin maturity as well as hemoglobin, melanin, and bilirubin concentrations. The investigators will extract spectra for each chromophore and the relative concentration from the Diffuse Reflectance Spectroscopy measurements. Extracted Diffuse Reflectance Spectroscopy spectra will be compared to published absorbance spectra for each chromophore. The criteria for success will be a high, positive correlation (r ≥ 0.85) between the extracted Diffuse Reflectance Spectroscopy bilirubin concentration and BiliChek-derived concentration.
The following coded data will also be collected to investigate correlations with the Diffuse Reflectance Spectroscopy spectra: blood oxygen saturation, weight, ethnicity, corrected age, gestational age, sex, most recent complete blood count (if available, or partial count if not), most recent chemistry levels, lipids, liver profile, and blood gas (all if available). BiliChek measurements of bilirubin content will be compared to the extracted bilirubin contribution measured from the Diffuse Reflectance Spectroscopy spectra using linear regression and assessed using Pearson's correlation coefficient.

Questions about this trial
What is this clinical trial studying?
A study testing Diffuse Reflectance Spectroscopy and BiliChek in people with Skin Disorder, run by University of Arkansas 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 2 inclusion and 6 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 26 Nov 2025. 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.
Are results available for this study?
Yes. Results are posted in the registry (first posted 22 Oct 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Bilirubin Concentration From Non-invasive Diffuse Reflectance Spectroscopy (DRS) vs BiliChek (time frame: 15 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 NCT05127044, which also lists 6 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 26 Nov 2025.
