Evaluation of the Safety and the Preterm Birth Predictive Capacity of the Clinical Investigation Device 'Cervisense TPTL': an International Clinical Study
Evaluation of the Safety and the Preterm Birth Predictive Capacity of the Clinical Investigation Device 'Cervisense TPTL': an International Clinical Study
The goal of this clinical trial is to evaluate the safety and the ability of a clinical investigation device (Cervisense TPTL) to predict the risk of spontaneous preterm birth in pregnant women with symptoms of threatened preterm labor (TPTL), between 28+0 and 36+6 weeks of gestation. The main questions it aims to answer are:
Does the Cervisense TPTL device predict spontaneous preterm birth within 7 days?
Is the device safe and technically reliable in a hospital setting?
Researchers will conduct a Pilot Study (randomized, dual-arm) followed by a Pivotal Study (single-arm) to assess technical feasibility and predictive performance.
Participants will undergo an intravaginal measurement of cervical stiffness using the Cervisense Intravaginal Probe. They will be followed for 14 days after the assessment to record delivery outcomes and any adverse events.
The study titled "Evaluation of the safety and the preterm birth predictive capacity of the clinical investigation device 'Cervisense TPTL': an international clinical study" is designed to assess both the safety and performance of the Cervisense TPTL device in predicting spontaneous preterm birth. It is being conducted across various Gynaecology, Obstetrics, and Emergency Services in hospitals throughout Spain and Germany.
Cervisense TPTL is the investigational product being evaluated. It includes two components: the Cervisense Intravaginal Probe V0.1, which measures cervical stiffness, and the Fine Birth algorithm, which combines the measurement with clinical data to assess the short-term risk of spontaneous preterm labor.
The device is intended for use in pregnant women showing symptoms of threatened preterm labor (TPTL), with intact amniotic membranes and a single fetus, between 28 weeks and 36 weeks plus 6 days of gestation. Its purpose is to determine the risk of spontaneous preterm birth within the following 7 days.
The clinical investigation is structured in two phases. The pilot study is a randomized, dual-arm, open-label, interventional, multi-centre study conducted in Spain. Participants are randomized 1:1 to receive either the standard of care or the Cervisense evaluation. The pivotal study is non-randomized and single-arm, also open-label and interventional, conducted at a larger scale across multiple centres in both Spain and Germany.
The main goal is to confirm that the device is safe to use and reliable in clinical settings. For safety, all adverse events associated with the use of the device are documented and analyzed in terms of severity, duration, and required intervention. Special attention is given to potential complications such as tissue trauma or infection. To ensure unbiased evaluation, a Clinical Events Committee and a Data Safety Monitoring Board have been established to independently review adverse events and guide study continuation.
