About this study

Official title: A Randomised Intervention Single Center Study to Determine the Role of Fatty Acids in Serum in Preventing Retinopathy of Prematurity

Most fatty acids, important for development and especially the Omega-3 fatty acids for the brain development are transferred in the third trimester with means that in the premature infant this transport via the placenta is interrupted and the infant is dependent on the concentrations in breast milk which vary depending on the mother's diet and her stores. It has even been suggested that low Omega-3 would be a cause of premature delivery. Many countries have much higher levels of Omega-3 fatty acids in breast milk than found in Sweden and breast milk substitutions are generally now supplemented with the Long Chained Poly Unsaturated Fatty Acids (LCPUFA). Therefore the supplementation to be given can not be seen to give any risks for the infant. On the contrary, several studies have shown that mother who eat equal to or less than twice fish a week during pregnancy give birth to infants with impaired development.

Low Omega-3 levels in premature infants between gestational ages of 23 and 40 weeks can be one reason for Retinopathy of Prematurity (ROP) development. Restoration of Omega-3, Dokosahexaenacid (DHA) and Eikosapentaenacid (EPA) to normal in utero levels may prevent ROP by allowing normal vessel growth and survival. An increase of Omega-3 levels bringing levels to within physiological range may prevent development of ROP.

Read the detailed description

The study is a Randomised Intervention, Single-Center Study to Determine the Role of Fatty Acids in Serum and Breast Milk in preventing Retinopathy of Prematurity.

Subjects who meet all inclusion and none of the exclusion criteria will be enrolled into the study. Upon entry into the study, subjects will be randomized and given a unique subject number.

A randomised intervention study of 45+45 infants without major malformations born with a gestational age less than 28 weeks + 0 days will be performed.

Randomization of the patients to either:

  1. Conventional fatty acid supplementation regime with Clinoleic (with Vitalipid infant and Soluvit supplementation) to the preterm infant Or
  2. SMOFlipid, (soybean oil, medium chain triglycerides, olive oil and fish oil),(with Vitalipid infant and Soluvit supplementation), where the quotient of Omega 6:3 is 2.5:1 in order to mimic the physiologic relation of fatty acids in cord blood from birth, to the preterm infant.

Thus there is one group of infants (n=45) that will receive Omega-3 in the fatty acid supplementation.

The time on parenteral nutrition and the amount of fatty acids given will be according to clinical routines.

The randomization of the patients will be performed by the controller of the study. Randomization will be in blocks with 10 children in each block.

Data collection

After the investigators have received informed consent from the parents/guardians, blood samples 0.2 ml from the child will be taken according to present clinical practice at if possible from cord (2ml) and at days 0, 7, 14, 28 and in postmenstrual weeks 32, 36 and 40. Blood samples from the mothers for Fatty Acids analyses will be taken after birth, day 7 and at gestational weeks 36 and 40. At the same time (except from day 1), breast milk samples are taken. Length in cm, weight in gram and head circumference in cm are measured weekly.

Screening for ROP will be performed, at least once a week, according to clinical routines using a specific protocol.

The investigators intend to analyze the content of phospholipids which can be done on small amounts of blood, is relatively insensitive to short term fluctuations in intake and mirror the composition of many membranes in the body. The analyses will be made using gas-liquid chromatography. The method has a coefficient of variability of 1-3% for the Fatty Acids concerned.

What is being measured

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

  1. Retinopathy of Prematurity

    We intend to analyze the content of Fatty Acids and correlate to Retinopathy of Prematurity development and interventional treatment. Analyze of phospholipids can be done on small amounts of blood, is relatively insensitive to short term fluctuations in intake and mirror the composition of many membranes in the body. The analyses will be made using gas-liquid chromatography. The method has a coefficient of variability of 1-3% for the Fatty Acids concerned.

    Measured: When the retina is fully vascularised,i.e. at approximately 40 postmenstrual weeks.

Secondary outcomes (4)
  1. Brain Growth

    Cranial ultrasound will be performed according to clinical praxis. MRI of the brain will be performed at 40 weeks postmenstrual age (PMA) and correlated to interventional treatment.

    Measured: At 40 postmenstrual weeks and at 2.5 and 6 years.

  2. Length in cm

    Length in cm given in absolute values and in standard deviation scores, at 40 weeks postmenstrual age (PMA) and at 2.5 and 6 years will be correlated to interventional treatment.

    Measured: At 40 postmenstrual weeks and at 2.5 and 6 years.

  3. Weight in gram

    Weight in gram given in absolute values and in standard deviation scores, at 40 weeks postmenstrual age (PMA) and at 2.5 and 6 years will be correlated to interventional treatment.

    Measured: At 40 postmenstrual weeks and at 2.5 and 6 years.

  4. Head circumference in cm

    Head circumference in cm given in absolute values and in standard deviation scores, at 40 weeks postmenstrual age (PMA) and at 2.5 and 6 years will be correlated to interventional treatment.

    Measured: At 40 postmenstrual weeks and at 2.5 and 6 years.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing SMOFlipid and Clinoleic in people with Retinopathy of Prematurity, run by Carola Pfeiffer-Mosesson.

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 5 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 3 May 2016. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Retinopathy of Prematurity (time frame: When the retina is fully vascularised,i.e. at approximately 40 postmenstrual weeks.). 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 NCT02760472, which also lists 4 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 3 May 2016.
