Trial summary

Preterm birth is a leading global cause of neonatal mortality despite of numerous advances and intensive research in perinatal medicine. Almost one million children die each year due to complications of preterm birth and in almost all countries with reliable data, preterm birth rates are increasing. Read more about this study

About this study

Official title: Cervix Monitor for Risk Assessment of Spontaneous Preterm Delivery

Preterm birth is a leading global cause of neonatal mortality despite of numerous advances and intensive research in perinatal medicine. Almost one million children die each year due to complications of preterm birth and in almost all countries with reliable data, preterm birth rates are increasing. Of the 14 million survivors per year, many face a lifetime of disability, including learning disabilities, visual and hearing impairments. Spontaneous preterm delivery (SPTD) is often multi factorial event, precocious cervical softening, shortening and dilatation are a common denominator. The majority of preterm births happen spontaneously, though some are due to early induction of labor or cesarean birth, typically due to medical maternal of neonatal conditions.

Read the detailed description

The uterine cervix has to provide structural integrity and mechanical resistance to ensure normal development of the fetus as the uterus expands to accommodate the fetus growth. Preterm delivery is closely related to a premature cervical ripening. The scientific bases for the proposed project is the elasticity modulus of a cervix is a more sensitive parameter characterizing the stage of cervical ripening. The main component of the cervix tissue is a collagen. Cervical ripening is the result of realignment of collagen, degradation of collagen cross-linking due to proteolytic enzymes. These processes affect the elasticity modulus of the cervical tissue. Therefore, assessment of cervix by a device measuring cervical elasticity and cervical length appears to be and adequate approach for identifying pregnant women at high risk of spontaneous preterm delivery. The primary cervical elasticity assessment currently used in clinical practice is relying on the evaluation of the cervix as "hard, medium or soft". In the scope of this project the investigators propose to develop and clinically validate a new and cost-effective device, Cervix Monitor for detecting cervix conditions leading to SPTD and its risk assessment. The CM will be based on measuring of the applied pressure to the cervix by a tactile sensor array and ultrasound measurement of cervix length .

Questions about this trial

What is this clinical trial studying?

An observational study of Preterm Birth, run by Advanced Tactile Imaging, Inc. at 2 sites 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 3 inclusion and 13 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 17 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 14 Apr 2020). 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?

Cervix Elasticity (time frame: During examination procedure). 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 NCT03199079, which also lists 1 linked publication.

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 17 Oct 2022.
