Trial summary

This project aims at unravelling mechanisms by which exposure to air pollution (in particular Ultrafine Particulate (UFP, PM0.1), and micro nano plastic's) interferes with the normal foetus development, with a short-term causal effect in higher likeliness of preterm delivery which, in consequence, precondition a… Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Study population: Pregnant mothers will be recruited at the first antenatal visit (around eight weeks of gestation).

Who may be able to join

  • Agreement to sign the informed consent;
  • Non-smoking mothers and no exposure to environmental (second-hand) smoke (smoking influences UFP measurements);
  • ≥18 years old (mothers have to place sensors, mothers with childhood pregnancies may live at their parental home);
  • Not expecting to terminate the pregnancy (no measurements of the child);
  • Having resided in the geographical area of research for a minimum period of 1 year (to be eligible for modeling exposures).

Who cannot join

  • First visit after 11 weeks of gestation (to ensure 2-week monitoring in the first trimester);
  • Pregnancy complications that limit exposure measurements in urine (because it may cause polyuria, for example, gestational diabetes);
  • Known kidney disease (might influence exposure measurements in urine);
  • Multiple pregnancy (twin or more pregnancies may have a higher risk for complications or preterm birth, no measurements in the last trimester).

About this study

Official title: UPRISE Unravelling Ultrafine Particulate Matter and Micro Nano Plastic's Mechanisms of Impact on Fetal Health

This project aims at unravelling mechanisms by which exposure to air pollution (in particular Ultrafine Particulate (UFP, PM0.1), and micro nano plastic's) interferes with the normal foetus development, with a short-term causal effect in higher likeliness of preterm delivery which, in consequence, precondition a higher likeliness to suffer non-communicable diseases (NCD) later in the life.

Read the detailed description

The characteristics of this study population are as follows:

  1. Case-control design The study includes 1600 participants, providing a substantial sample for analysis. The focus is on newborns (age 0), making the study particularly relevant for understanding factors and outcomes related to this very early stage of life. The sex of the participants is expected to be randomly distributed. A control arm of full-term neonates (>37 weeks) will be recruited for a 1:2 ratio in Greece and Spain.
  2. Personal Exposure Monitoring PEM Substudy:

The study consists of 150 mothers, with 50 from each location. All participants are females aged over 18 years. The sex of the participants is expected to be randomly distributed.

Questions about this trial

What is this clinical trial studying?

An observational study of Pregnant Women, run by Instituto de Investigacion Sanitaria La Fe at 1 site in Spain.

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 5 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 20 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 Spain. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Alba Ruiz Gaitán, Dr (0034961246690, alba_ruiz@externos.iislafe.es), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PreTerm Birth (time frame: at the moment of birth). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Nov 2025.
