NCT ID: NCT06089434 Recruiting - Dysphagia Clinical Trials

TEE and Dysphagia in Lung Transplantation

Start date: June 2024
Phase: N/A
Study type: Interventional

The primary outcome of this study is dysphagia (difficulty swallowing) on postoperative speech and swallow evaluation following lung transplantation. Transesophageal echocardiography (TEE) (creates pictures of the heart from inside the participants body) is routinely performed for all lung transplantations at the University of California, Los Angeles (UCLA) and it is the standard of care. Patients are randomized to two groups. The intervention group would limit the number of TEE clips (# pictures taken) per case. The control group would leave the number of TEE clips to the discretion of the attending anesthesiologist. The investigators hypothesize that reduction in TEE imaging during lung transplantation will reduce dysphagia.

NCT ID: NCT06033196 Recruiting - Lung Transplant Clinical Trials

Tocilizumab in Lung Transplantation

ALL IN LUNG
Start date: February 13, 2024
Phase: Phase 2
Study type: Interventional

This is a trial in which 350 primary lung transplant recipients will be randomized (1:1) to receive either Tocilizumab (six doses over 20 weeks) plus standard triple maintenance immunosuppression or placebo (sterile normal saline) plus standard triple maintenance immunosuppression (Tacrolimus, Mycophenolate Mofetil, corticosteroids).

NCT ID: NCT05898776 Recruiting - Lung Transplant Clinical Trials

10°C vs 4°C Lung Preservation RCT

Start date: June 9, 2023
Phase: N/A
Study type: Interventional

Despite lung transplantation (LTx) being the most effective treatment for end-stage lung disease, its success rate is lower than that of other solid organ transplantations. Primary graft dysfunction (PGD) is the most common post-operative complication and a major factor in early mortality and morbidity, affecting ~25% of lung transplant patients. Induced by ischemia reperfusion, PGD represents a severe and acute lung injury that occurs within the first 72 hours after transplantation, and has a significant impact on short- and long-term outcomes, and a significant increase in treatment costs. Any intervention that reduces the risk of PGD will lead to major improvements in short- and long-term transplant outcomes and health care systems. One of the main strategies to reduce the risk and severity of post-transplant PGD is to improve pre-transplant donor lung preservation methods. In current practice, lung preservation is typically performed by cold flushing the organ with a specialized preservation solution, followed by subsequent hypothermic storage on ice (~4°C). This method continues to be used and applied across different organ systems due to its simplicity and low cost. Using this method for the preservation of donor lungs, the current maximum accepted preservation times have been limited to approximately 6-8h. While the goal of hypothermic storage is to sustain cellular viability during ischemic time through reduced cellular metabolism, lower organ temperature has also been shown to progressively favor mitochondrial dysfunction. Therefore, the ideal temperature for donor organ preservation remains to be defined and should maintain a balance between avoidance of mitochondrial dysfunction and prevention of cellular exhaustion. In addition to that, safe and longer preservation times can lead to multiple advantages such as moving overnight transplants to daytime, more flexibility to transplant logistics, more time for proper donor to recipient matching etc. Building on pre-clinical research suggesting that 10°C may be the optimal lung storage temperature, a prospective, multi-center, non-randomized clinical trial was conducted at University Health Network, Medical University of Vienna and Puerta de Hierro Majadahonda University Hospital. Donor lungs meeting criteria for direct transplantation and with cross clamp times between 6:00pm - 4:00am were intentionally delayed to an earliest allowed start time of 6:00am and a maximum preservation time from donor cold flush to recipient anesthesia start time of 12 hours. Lungs were retrieved and transported in the usual fashion using a cooler with ice and transferred to a 10°C temperature-controlled cooler upon arrival to transplant hospital until implantation. The primary outcome of this study was incidence of Primary Graft Dysfunction (PGD) Grade 3 at 72h, with secondary endpoints including: recipient time on the ventilator, ICU Length of Stay (LOS), hospital LOS, 30-day survival and lung function at 1-year. Outcomes were compared to a contemporaneous conventionally transplanted recipient cohort using propensity score matching at a 1:2 ratio. 70 patients were included in the study arm. Post-transplant outcomes were comparable between the two groups for up to 1 year. Thus, intentional prolongation of donor lung preservation at 10°C was shown to be clinically safe and feasible. In the current study design, the investigators will conduct a multi-centre, non-inferiority, randomized, controlled trial of 300 participants to compare donor lung preservation from the time of explant to implant at ~10°C in X°Port Lung Transport Device (Traferox Technologies Inc.) vs a standard ice cooler. When eligible donor lungs become available for a consented recipient, the lungs will be randomized to undergo a preservation protocol using either 10°C (X°Port Lung Transport Device, Traferox Technologies Inc.) or standard of care. The primary outcome of the study is incidence of ISHLT Primary Graft Dysfunction Grade 3 at 72 hours. Post-transplant outcomes will be followed for one year.

NCT ID: NCT05581745 Recruiting - Lung Transplant Clinical Trials

A2 to O Lung Transplants

Start date: July 14, 2022
Phase: N/A
Study type: Interventional

Blood group A2 to blood group O kidney and liver transplants have been shown to be safe and successful, especially in recipients with low pre-operative anti-A antibody titers and with the use of peri-operative antibody-depleting therapies. Since blood group O lung transplant candidates tend to have longer wait times and a higher waitlist mortality compared to other blood groups, we propose to conduct a prospective study of lung transplantation from blood group A2 donors to eligible blood group O recipients in an effort to increase the available donor pool. The aim of this study is to determine both the feasibility and safety of this specific type of ABO-incompatible lung transplant, and the impact of this practice on reducing transplant wait times among blood group O lung transplant candidates. This would represent the first prospective study of ABO-incompatible lung transplants worldwide.

NCT ID: NCT05195853 Recruiting - Lung Transplant Clinical Trials

Optimization of Donor-Recipient Matching in Lung Transplantation

ADRTP
Start date: January 15, 2022
Phase:
Study type: Observational

Lung transplantation is the curative treatment for end-stage respiratory failure involving highly selected patients. In 2018, the International Transplant Registry counts 69200 lung transplants among 260 transplant centers. Between 2010 and June 2017, the 3-month survival rate of patients after lung transplantation is 90%. The causes of early death are primary graft failure, renal failure, infections, acute rejection (cellular or humoral), surgical complications. The median survival is 6.7 years and the median conditioned survival at 1 year is 8.9 years. Bronchiolitis obliterans is the leading cause of death after 1 year; it affects 10% more patients each year and peaks at 5 years at more than 50% of transplanted patients. These results encourage transplant professionals to continue their efforts to improve the prognosis of transplantation. Among these, the optimization of graft matching, taking into account the characteristics of the donor and the recipient, constitute a relevant avenue of study. Several donor characteristics seem to play a role in the prognosis of the transplant. Survival at 12 months is significantly worse when the donor's age is greater than 50 years. There does not appear to be a significant difference in donor cause of death. Recipients of a graft exposed to smoking ≥ 20 pack-years have a 3% and 1.5% decreased survival at 1 and 5 years postoperatively. Similarly, the 5-year survival of patients with conditional 1-year survival is poorer in case of other toxic exposures such as alcohol, cocaine, crack or marijuana. Analysis of international registry data also suggests a negative association between post-transplant survival and donor hypertension and diabetes. However, the biological mechanisms by which these factors affect survival remain unknown. Graft ischemia time is significantly associated with survival with a 5-year survival of 70% and 65% for grafts exposed to ischemia ≥ 4 hours or less. The cumulative effect of donor hypertension and ischemia time are appreciated by the fact that the best postoperative survival is observed in donors without hypertension and graft ischemia time ≥ 4 hours. Graft size is also associated with post-transplant prognosis, in front of a significant decrease in survival for patients with emphysema, chronic obstructive pulmonary disease, alpha-1 antitrypsin deficiency, transplanted with a smaller graft size. This result is not found in patients transplanted for pulmonary fibrosis. One study has also suggested the negative role of a gender mismatch between donor and recipient on post-transplant survival, but there is currently no clear explanation for this result. The presence of antibodies to the recipient's HLA system [DSA (donor-specific antibodies)] in pre-transplant is a risk factor for hyperacute rejection and chronic graft dysfunction. Thus, the choice of matching between the donor and the recipient appears complex in view of the number of criteria to be taken into account which impact the duration of post-transplant survival in the short and medium term. The objective of the project is to develop a decision support tool, using artificial intelligence algorithms, to assist the thoracic surgeon in identifying the patient, among those registered on the team's waiting list, who could benefit most from a bi-pulmonary graft offered by the Biomedicine Agency.
