급성호흡곤란증후군(ARDS) 치료를 위한 흡입형 일산화탄소의 안전성 및 유효성 연구
급성호흡곤란증후군(ARDS) 치료를 위한 흡입형 일산화탄소의 II상 시험
연구 개요
상세 설명
급성호흡곤란증후군(ARDS)은 군인, 퇴역 군인 및 민간인에게 영향을 미치는 치명적인 질병입니다. ARDS는 미국에서 매년 180,000건 발생하는 심각한 급성 폐 염증 및 저산소혈증성 호흡 부전의 증후군입니다. 중환자 관리 및 폐 보호 환기 전략의 최근 발전에도 불구하고 ARDS 이환율과 사망률은 용납할 수 없을 정도로 높습니다. ARDS에 대한 구체적이고 효과적인 치료법이 없다는 것은 새로운 경로를 목표로 하는 새로운 치료법이 필요함을 나타냅니다. 일산화탄소(CO)는 지난 10년 동안 ARDS의 실험 모델에서 얻은 데이터를 기반으로 ARDS의 새로운 치료 방식을 나타냅니다.
CO는 급성 폐 손상(ALI) 및 패혈증의 실험 모델에서 보호적인 것으로 나타났습니다. 더욱이, 다수의 인간 연구는 여러 다른 농도의 CO의 실험적 투여가 잘 견디며 저용량 흡입 CO가 통제된 연구 환경에서 피험자에게 안전하게 투여될 수 있음을 입증했습니다. 연구자들은 이전에 저용량 iCO(100 및 200ppm)의 정확한 투여가 패혈증 유발 ARDS 환자에서 실행 가능하고 내약성이 우수하며 안전하다는 것을 입증한 ARDS에서 저용량 iCO의 1상 시험을 수행했습니다.
이 연구의 목적은 기계적 환기를 받는 ARDS 환자에서 저용량 흡입 일산화탄소(iCO) 요법의 안전성과 효능을 평가하는 것입니다.

Primary Safety Outcome: Number of Pre-specified Administration-related Adverse Events.
기간: 7 days
|
Safety of inhaled CO, defined by the incidence of pre-specified administration-related AEs (as defined below) and spontaneously reported AEs through study day 7.
|
7 days
|
|
Primary Efficacy Outcome: Change in Mitochondrial DNA (mtDNA) Level From Day 1 to Day 5
기간: 5 days
|
Mitochondrial DNA (mtDNA) plasma levels will be measured by quantitative PCR of human NADH dehydrogenase 1.
The number presented is the percentage average difference from beginning to end of treatment.
Limited number of measurements prevents variance analyses; therefore we present the data from the subjects available in each group and report as "Mean" without standard deviation, where measures of dispersion cannot be calculated.

Lung Injury Score (LIS) on Days 1-5, and on Days 1-7
기간: 7 days
|
The Lung Injury Score (LIS) is a composite 4-point scoring system including the PaO2/FiO2, PEEP, quasi-static respiratory compliance, and the extent of infiltrates on the chest X-ray.
Each of the four components is categorized from 0 to 4, where a higher number is worse.
The total Lung Injury Score is obtained by dividing the aggregate sum by the number of components used.
Previous randomized clinical trials in ARDS have shown that a decreased LIS correlates with improvement in lung physiology as well as important clinical outcomes including mortality and ventilator-free days (VFDs).
The number presented is the average difference from beginning to end of treatment.
The limited number of measurements prevent the variance and measures of dispersion calculations; therefore we present the average of data from the available subjects in each group and report as "Mean" without standard deviation, where measures of dispersion cannot be calculated.

Percent Change in PaO2/FiO2 Ratio on Days 1-5, and on Days 1-7
기간: 7 days
|
PaO2/FiO2 will be measured daily on days 1-5 and days 1-7 in ventilated subjects.
The limited number of measurements prevent the variance and measures of dispersion calculations; therefore we present the average of data from the available subjects in each group and report as "Mean" without standard deviation, where measures of dispersion cannot be calculated.

Percent Change in Oxygenation Index (OI) on Days 1-5, and Days 1-7
기간: 7 days
|
The oxygenation index will be measured on days 1-5 and on days 1-7 in ventilated subjects.
Oxygenation index is calculated as (FiO2 X mean airway pressure)/PaO2.
We provide change in Oi from baseline.
Oi is only measured when subjects are ventilated, therefore not all timepoints are available.
The limited number of measurements prevent the variance and measures of dispersion calculations; therefore we present the average of data from the available subjects in each group and report as "Mean" without standard deviation, where measures of dispersion cannot be calculated.

Percent Change in Dead Space Fraction (Vd/Vt) on Days 1-3, and Days 1-7
기간: 7 days
|
The dead space fraction will be measured days 1-3 and days 1-7 in ventilated subjects.
We present change in dead space fraction between initial and final measurements that were available (measurements only taken while the subjects were intubated).
The limited number of measurements prevent the variance and measures of dispersion calculations; therefore we present the average of data from the available subjects in each group and report as "Mean" without standard deviation, where measures of dispersion cannot be calculated.

Percent Change in Sequential Organ Failure Assessment (SOFA) Score on Days 1-5, and Days 1-7.
기간: 1-5 and 1-7 days
|
Organ failure will be assessed using the SOFA score.
SOFA scores will be assessed daily on days 1-5 and day 7, as the SOFA score has been shown to be a reliable prognostic indicator of outcomes in critically ill patients.
To calculate the Sequential Organ Failure Assessment (SOFA) score, each of the six components (Respiratory, Coagulation, Liver, Cardiovascular, Central Nervous System, Renal) is categorized from 0-4, where a higher number is worse.
The SOFA score (0-24) will be calculated by summing all six components.
We present changes in SOFA score over the time of hospitalization, over the time of ICU admission (up to days 5 and 7 for the enrolled subjects).
The limited number of measurements prevent the variance and measures of dispersion calculations; therefore we present the average of data from the available subjects in each group and report as "Mean" without standard deviation, where measures of dispersion cannot be calculated.

Absolute Value of Biomarkers of Inflammation and Inflammasome Activation
기간: 4 days
|
Cytokine plasma levels (eg.
IL-1B) will be measured by ELISA daily on days 1-3 and on day 4. We report the absolute Mean Fluorescent Intensity (MFI) of each sample at pretreatment time point of day 4. Limited number of measurements prevents variance and measures of dispersion analyses; therefore we present the data from the subjects available in each group and report as "Number" without standard deviation, since measures of dispersion cannot be calculated.

Percent Change in Lipid Mediators
기간: 4 days
|
Lipid mediators (LM) and specialized pro-resolving mediators (SPMs) will be measured in plasma using liquid chromatography-tandem mass spectrometry (LC-MS-MS) based methods daily on days 1-3 and on day 4.
The percentage change from baseline at day 1 to post treatment at day 4 is reported.
A representative LM is shown (14-HDHA (14-hydroxy-4Z,7Z,10Z,12E,16Z,19Z-docosahexaenoic acid) is an oxidized metabolite of omega-3 docosahexaenoic acid (DHA)).
Limited number of measurements prevents variance and measures of dispersion analyses; therefore we present the data from the subjects available in each group and report as "Number" without standard deviation, since measures of dispersion cannot be calculated.

Ventilator-free Days at Day 28
기간: 28 days
|
Ventilator-free days to day 28 are defined as the number of days from the time of initiating unassisted breathing to day 28 after randomization, assuming survival for at least two consecutive calendar days after initiating unassisted breathing and continued unassisted breathing to day 28.
If a subject returns to assisted breathing and subsequently achieves unassisted breathing to day 28, VFDs will be counted from the end of the last period of assisted breathing to day 28.
Participants who do not survive to day 28 are assigned zero ventilator-free days.
The limited number of measurements prevent the variance and measures of dispersion calculations; therefore we present the average of data from the available subjects in each group and report as "Mean" without standard deviation, where measures of dispersion cannot be calculated.

ICU-free Days at Day 28
기간: 28 days
|
ICU-free days are the number of days that the patient is alive and free from ICU care within 28 days.
Is calculated by subtracting the total number of days that the patient is free from the ICU from 28. Patients who die within 28 days are automatically assigned "0" ICU free days.
We present data of ICU free days for enrolled subjects.
The limited number of measurements prevent the variance and measures of dispersion calculations; therefore we present the average of data from the available subjects in each group and report as "Mean" without standard deviation, where measures of dispersion cannot be calculated.

Hospital-free Days at Day 60
기간: 60 days
|
Hospital-free days will be assessed on day 60.
Hospital-free days are days alive post hospital discharge through day 60.
Patients who die on or prior to day 60 are assigned zero hospital-free days.
We present hospital free days at day 60.
The limited number of measurements prevent the variance and measures of dispersion calculations; therefore we present the average of data from the available subjects in each group and report as "Mean" without standard deviation, where measures of dispersion cannot be calculated.

Montreal Cognitive Assessment- MoCA-Blind
기간: 6 months
|
Montreal Cognitive Assessment - Blind Version (MoCA-Blind) The MoCA-Blind is a remote adaptation of the Montreal Cognitive Assessment (MoCA) used as a screening assessment for detecting cognitive impairment.
It is administered via telephone interview.
The MoCA-Blind assesses the following cognitive domains (points): - Attention (0-6) - Language: (0-3 (Repetition (0-2) and fluency (0-1)) - Abstraction (0-2) - Memory: Delayed recall (0-5) - Orientation (0-6) The minimum score is 0 and maximum score is 22 points.
Calculated as the sum of all domains.
Interpretation: Higher scores indicate better cognitive functioning.
Lower scores indicate worse cognitive functioning (greater cognitive impairment).
A score of 18 or above is within the normal range.
Limited number of measurements prevents variance and measures of dispersion analyses; therefore we present the data from the subjects available in each group and report as "Number", since given measures of dispersion cannot be calculated.

Hayling Sentence Completion Test
기간: 6 months
|
The Hayling Sentence Completion Test assesses executive functioning (response initiation and inhibition), administered via telephone.
With 30 sentence-completion items split into 2 sections (15 each).
Sections: - 1: Response initiation (time to provide a contextually appropriate word).
- 2: Response inhibition (time and error score for providing an unrelated word).
Scores (response time and errors) from both sections are combined and converted to an age-adjusted standardized total score.
Total combined standardized score ranges from 1-10: 1: Impaired 2: Abnormal 3: Poor 4: Low Average 5: Moderate Average 6: Average 7: High Average 8: Good 9: Superior 10: Very Superior Higher scores= Better executive functioning Lower scores= Greater impairment.
Limited number of measurements prevents variance and measures of dispersion analyses; therefore we present the data from the subjects available in each group and report as "Number", since given measures of dispersion cannot be calculated.
