Trial Outcomes & Findings for Efficacy and Safety of Plasma Exchange With Albumin in Patients With Amyotrophic Lateral Sclerosis (NCT NCT02479802)

NCT ID: NCT02479802

Last Updated: 2020-06-16

Results Overview

Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) includes 12 questions classified into 3 subdomains: bulbar function (3 questions), fine and gross motor skills (6 questions), and respiratory function (3 questions) to assess the level self sufficiency. Each task was graded according to a 5-point scale from 0 (incapable) to 4 (normal ability) with a total score from 0 (worst) to 48 (best).

SECONDARY outcome

Timeframe: Baseline, Weeks 25 and 48

Population: Two subjects discontinued from the study.

ALS-CBS test is composed of 2 sections. The first section of the ALS-CBS test includes a questionnaire completed by the caregiver regarding behavior and symptoms status. It is comprised of 15 questions inquiring about possible changes over time in participant's behavior that the caregiver has noticed since the onset of ALS symptoms. Each item is scored on a scale ranging from 0 (worst) to 3 (best) yielding a total 0= large changes to 45=no changes. There were 4 additional questions related to current behavioral symptoms (depression, anxiety, fatigue, and emotional liability). Each question was scored as 0= the presence of symptoms and 1= no current symptoms, giving a total score between 0 and 4. The second section of the ALB-CBS test is for cognitive screening and consists of four items: attention, concentration, follow-up and monitoring, and initiation and recovery. These items were scored 0-5 with a maximum score of 20 (0= cognitive impairment, 20= no apparent cognitive impairment).

The Amyotrophic Lateral Sclerosis Assessment Questionnaire 40 (ALSA-40) consists of 40 items grouped into 5 representative dimensions associated with quality of life. The first 4 scales (physical mobility, activities of daily living, food and drink, communication) refer to deficits and subsequent disabilities as a result of the disease. The fifth scale (emotional functioning) reflects how the subject is facing his/her physical deterioration emotionally. Each item is scored from 0 to 4 according to a gradation of symptom onset frequency (never, rarely, sometimes, often, and always). From raw scores, an index from 0 to 100 is obtained for each dimension, which allow comparisons to be made with the other dimensions as well as a straightforward interpretation of results (0 = better state of health as measured by the questionnaire; 100 = poorer state of health).
