Study summary

PrismaLung+ is a sterile, single-use medical device aimed at performing partial removal of carbon dioxide (CO2) from the patient's venous blood via diffusion through a membrane. The goal of this prospective, open label, randomized controlled study is to evaluate the efficacy and safety of PrismaLung+ on extracorporeal carbon dioxide removal (ECCO2R) in critically ill patients under invasive mechanical ventilation (IMV). Patients will be randomized to receive either IMV combined with ECCO2R (using PrismaLung+) in the study group or IMV alone in the control group, at a ratio of 2:1.

Terms in these criteria, in plain language(3)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Study arms

  • Experimental
    Patients receiving IMV combined with ECCO2R

    Patients will receive IMV combined with ECCO2R using PrismaLung+.

    Device: PrismaLung+

  • Active comparator
    Patients receiving IMV alone

    Other: Invasive Mechanical Ventilation

Interventions

  • DevicePrismaLung+

    PrismaLung+ is a medical device that provides ECCO2R as a stand-alone therapy or in combination with CRRT. The planned treatment duration with PrismaLung+ for patients in the study group is 7 days. However, the Investigator can discontinue PrismaLung+ treatment before 7 days if ECCO2R is no longer required. Following the 7-day treatment period, the Investigator will assess the patient's condition to determine whether to continue ECCO2R. Patients will require systemic anticoagulation with heparin during ECCO2R treatment. Continuous renal replacement therapy may be administered concurrently to patients during the study, if needed, at the discretion of the Investigator. During the study, patients will be given active treatment for their primary disease.

  • OtherInvasive Mechanical Ventilation

    According to the standard clinical practice of IMV, oral or nasal endotracheal intubation can be used for IMV. The initial mode of IMV and ventilatory parameters will be determined based on the patient's condition, and an appropriate patient-centered LPV approach will be selected to adjust the ventilatory parameters to achieve the study LPV strategy. Appropriate treatments other than ECCO2R will be provided for this group. Continuous renal replacement therapy may be administered concurrently to patients during the study, if needed, at the discretion of the Investigator. During the study, patients will be given active treatment for their primary disease.

What researchers measure

Primary outcomes

  1. The percent decrease of partial pressure of carbon dioxide (PaCO2) from baseline after 2h of treatment.

    Percent decrease (%) of PaCO2 from baseline based on arterial blood gas 2h after treatment initiation. Must meet the following requirements for data collection: 1. maintained LPV (RR \< 25/min, DP \< 15 cmH2O) with consistent ventilatory parameters with baseline; 2. blood flow rate (Qb) of 300 to 450 mL/min; 3. sweep gas flow rate of 10 L/min.

    Time frame: 2 hours after treatment

Secondary outcomes

  1. CO2 clearance (in the experimental group only)

    Blood sampled pre- and post-PrismaLung+ filter to calculate CO2 clearance based on blood gas analysis results.

    Time frame: 2 hours and 24 hours after treatment

  2. Changes in Blood Gas Indexes

    Change in blood gas indexes before and after treatment based on arterial blood gas at different follow-up timepoints. Blood gas indexes include pH, PaO2, PaCO2, SaO2, standard bicarbonate (SB), actual bicarbonate (AB), and lactic acid.

    Time frame: 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, 2 days, 3 days, 7 days after treatment

  3. Changes in Oxygenation Indexes (PaO2/FiO2)

    The ratio of partial pressure of arterial oxygen (PaO2 in mmHg) to fraction of inspired oxygen (FiO2 in %), i.e., PaO₂/FiO₂.

    Time frame: 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, 2 days, 3 days, 7 days after treatment

  4. Changes in Ventilatory Parameters

    Changes in respiratory rate (RR). The following definitions on ventilatory parameters are for reference and the specific parameters are based on the ventilator mode at each site. RR refers to the number of breaths per minute of a ventilator, measured in breaths/min.

    Time frame: 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, 2 days, 3 days, 7 days after treatment

  5. Changes in Ventilatory Parameters

    Changes in tidal volume (VT). The following definitions on ventilatory parameters are for reference and the specific parameters are based on the ventilator mode at each site. VT refers to the volume of air delivered by a ventilator, measured in mL.

    Time frame: 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, 2 days, 3 days, 7 days after treatment

  6. Changes in Ventilatory Parameters

    Changes in driving pressure (DP). The following definitions on ventilatory parameters are for reference and the specific parameters are based on the ventilator mode at each site. DP refers to the driving pressure of a respiratory system, defined as tidal volume/respiratory system compliance. Respiratory system driving pressure = airway Pplat - PEEP, measured in cmH2O.

    Time frame: 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, 2 days, 3 days, 7 days after treatment

  7. Changes in Ventilatory Parameters

    Changes in positive end-expiratory pressure (PEEP). The following definitions on ventilatory parameters are for reference and the specific parameters are based on the ventilator mode at each site.

  10. Ventilator-Free Days

    The number of days between successful weaning from mechanical ventilation and the end of follow-up (28 days after treatment). Weaning from mechanical ventilation refers to the removal of mechanical ventilation for respiratory support and the resumption of complete spontaneous breathing, after the primary disease is controlled and the ventilation and gas exchange functions are improved in patients under mechanical ventilation (referred to as weaning from mechanical ventilation). Instead of using mechanical ventilation for respiratory support, the respiratory load of the body is borne entirely by the patient's own respiratory capacity. Spontaneous breathing: * The total respiratory rate of the patient is higher than that set in the assist-control mode during mechanical ventilation, or the mechanical ventilation mode requires the patient to breathe spontaneously. * No invasive respiratory support is provided.

    Time frame: 28 days after enrollment

  11. Days of ICU stay

    The span of time during which the patient receives treatment and care in the ICU within 28 days after treatment initiation.

    Time frame: 28 days after enrollment

  13. Quality of life (QoL)

    During the trial, for patients who regain consciousness, the differences in quality-of-life scores will be evaluated based on EQ-5D-5L assessments at the time of awakening and on Day 28 (if the patients are still alive).

    Time frame: 1 day of regaining consciousness, 28 days after enrollment.

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 Sep 16, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
