A Study of the Efficacy and Safety of Extracorporeal Carbon Dioxide Removal Using PrismaLung+

Condition(s) studied

Investigational drug(s) / intervention(s)

PrismaLung+: 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.

Invasive 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.

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.

Eligibility

Primary outcome measure(s)

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