Study summary

About 50% of full-term newborns and 80% of premature infants develop jaundice which is due to hyperbilirubinemia. In the majority of cases, jaundice disappears naturally without treatment within three weeks of birth, but the bilirubin level may remain too high, which can lead to a serious neurological disease: kernicterus. To avoid this, a therapeutic management must be instituted, and in some cases, one or more phototherapy sessions (PT) may be prescribed.

The aim of this trial is to evaluate the safety and level of satisfaction of parents and healthcare team with one innovative device for phototherapy BUBOLight® included two removable strips of luminous textile incorporating optical fibers.

10 newborns requiring phototherapy, will be illuminated during four hours in one session of PT Bilirubin levels is taken at the start of phototherapy H0 and Controls are made at H+6 hours.

Exclusion criteria

Exclusion Criteria:

  • Newborn already treated with phototherapy
  • Febrile state with body temperature > 37.8°C
  • Total bilirubinaemia level is equal or excess 100 μmol / L of the indication of phototherapy.
  • Patient whose jaundice is due to haemolysis, obstruction functional or anatomical.
  • Minor relative
  • Newborn requiring exchange transfusion
  • Newborn with congenital erythropoietic porphyria or a family history of porphyria.
  • Patient requiring treatment other than phototherapy
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

What researchers measure

Primary outcomes

  1. Number of related adverse events (Safety)

    Safety is defined as the ability to tolerate 4 hours of phototherapy without - Hyperthermia greater than or equal to 38.5 °C * Hypothermia less than or equal to 36 °C * Desaturation in O2 lower than 90% for more than 15 seconds * Heart rate greater than 160 / min at calm or less than 80 / min for more than 15 seconds * Allergic contact reaction grade ≥3

    Time frame: at the begin of phototherapy (baseline, H0)

  2. Number of related adverse events (Safety)

    Safety is defined as the ability to tolerate 4 hours of phototherapy without - Hyperthermia greater than or equal to 38.5 °C * Hypothermia less than or equal to 36 °C * Desaturation in O2 lower than 90% for more than 15 seconds * Heart rate greater than 160 / min at calm or less than 80 / min for more than 15 seconds * Allergic contact reaction grade ≥3

    Time frame: at 2 hours after the beginning of phototherapy (H2)

  3. Number of related adverse events (Safety)

    Safety is defined as the ability to tolerate 4 hours of phototherapy without - Hyperthermia greater than or equal to 38.5 °C * Hypothermia less than or equal to 36 °C * Desaturation in O2 lower than 90% for more than 15 seconds * Heart rate greater than 160 / min at calm or less than 80 / min for more than 15 seconds * Allergic contact reaction grade ≥3

    Time frame: at the end of phototherapy exposure (H4)

Secondary outcomes

  1. Blood bilirubin rate

    Bilirubin lowering rate

    Time frame: Baseline and 2 hours after the end of phototherapy (H4+2 hours)

  2. Transcutaneous bilirubin rate

    Bilirubin lowering rate

    Time frame: Baseline (H0) and 2 hours after the end of phototherapy (H4+2 hours)

  3. EDIN (Newborn Pain and Discomfort Scale)

    Variation of the EDIN score between the beginning and 2 hours after phototherapy Minimum value = 0 and maximum value = 15. Above 5 pain is probable, below 5 pain is more likely to be discomfort than pain.

    Time frame: Baseline (H0) and 2 hours after the end of phototherapy (H4+2 hours)

  4. Perceptions of parents with the use of device

    Validated survey at the end of treatment (comfort, heat, humidity, ease of breastfeeding, proximity and possibility of contact with the baby)

    Time frame: 2 hours after the end of phototherapy (H4+2 hours)

  5. Perceptions of the health team with the use of the device

    Validated survey at the end of treatment (comfort, heat, humidity, ease of breastfeeding, proximity and possibility of contact with the baby)

    Time frame: 2 hours after the end of phototherapy (H4+2 hours)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2020 (actual). Primary completion is estimated for Dec 2026, 74 months after the start.

Of 35 non-industry interventional studies with no phase under Jaundice, Neonatal, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 21. This study's planned 74 months is above that.

Counting every sponsor, half of 45 studies reached it within 11 months; a quarter within 5 and three quarters within 21.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 23, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
