Respiratory Failure Clinical Trial

Official title: Effects of Photobiomodulation Therapy Combined With Static Magnetic Field in Reducing the Number of Days in the Intensive Care Unit (ICU) for Adult Patients Requiring Mechanical Ventilation

Status Not yet recruiting

Clinical Trial Summary

The goal of this clinical trial is to evaluate the effectiveness of photobiomodulation therapy combined with static magnetic field (PBMT-sMF) in adult patients who require mechanical ventilation. The main questions it aims to answer are:

(i) Does PBMT-sMF lower the length of stay in the intensive care unit (ICU) for mechanically ventilated patients? (ii) Does PBMT-sMF increase the diaphragm thickness in mechanically ventilated patients in the ICU?

Researches will compare active PBMT-sMF plus standard of care to a placebo PBMT-sMF plus standard of care to see if active PBMT-sMF works to prevent or retard disuse atrophy of the diaphragm during mechanical ventilation.

Clinical Trial Description

To achieve the proposed objectives it will be performed a multi-center, randomized, triple-blinded (patients, therapists, outcome assessors), placebo-controlled trial, in patients who required mechanical ventilation.

One hundred and twelve patients will be randomly allocated to two treatment groups:

1. Active treatment: Patients will receive treatment with the active PBMT-sMF combined with standard of care therapy for a mechanically ventilated patient in the ICU.

2. Placebo treatment: Patients will receive treatment with the placebo PBMT-sMF combined with standard of care therapy for a mechanically ventilated patient in the ICU.

The randomization will occur immediately following patients qualification and prior to any additional study activities occurring.

The treatment administration protocol (28-day administration protocol) will comprise:

7-minute treatment administration per day on each consecutive day for four consecutive weeks, for a maximum of 28 consecutive treatments over 28 consecutive days, or until the day of the patient's successful weaning from mechanical ventilation, or until the day of the patient's death, whichever occurs first.

The data will be collected by a blinded assessor.

Due to the nature of the condition being evaluated in this study, the study assessment timeline is patient dependent and will therefore be unique to each patient.

The study will comprise:

1. pre-treatment evaluation phase (before starting treatment);

2. treatment administration phase (two assessments: after completion of 14 and 28 days of treatment);

3. post-treatment evaluation phase (any patient who is not discharged from the hospital or who does not die during the treatment administration and evaluation phase will proceed to the post-treatment administration phase. The post-treatment phase will start on the day immediately following the patient's last day in the treatment administration evaluation phase. The post-treatment phase will end on the day that the patient is discharged from the hospital, or the day that the patient dies prior to discharge from the hospital, whichever occurs firs. Therefore, the duration of the post-treatment administration phase will vary by individual patient. During the post-treatment evaluation period, the following assessments will be recorded once every two weeks, as applicable, with the final post-treatment evaluation visit determined on an individual patient basis, up to 2 years).

P.S.:

• For patients whose successful weaning from mechanical ventilation occurs prior to completion of the 28-day administration protocol, the endpoint assessment visit will occur on or after the day of successful weaning.

• For patients who die before completion of the 28-day administration protocol, the endpoint assessment visit will include outcome measures recorded as close to the date of the patient's death as possible.

The investigators will analyze: 1) Length of stay in the ICU; 2) Diaphragm thickness; 3) Length of stay in the hospital following ICU discharge; 4) Length of time until weaning from mechanical ventilation; 5) Mechanical ventilation parameters: (i) Positive end-expiratory pressure levels (PEEP) and (ii) Fraction of inspired oxygen (FiO2); 6) Arterial blood gas analysis: (i) Arterial partial pressure of oxygen (PO2) and (ii)PO2/FiO2 ratio; 7) Vital signs: blood pressure, heart rate, SpO2, blood glucose, etc.; 8) Blood draw analysis: C-reactive protein (CRP); Tumor necrosis factor-alpha (TNF-α); Vitamin D; erythrocytes; hemoglobin; hematocrit; leucocytes; segmented neutrals; eosinophiles; basophiles; lymphocytes; monocytes; platelet count;8) Survival rate; 9) Local skin reactions; 10) Adverse events and serious adverse events.

The statistical analysis will follow the intention-to-treat principles. ;
