Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Albutein 5%

Arm Description

Plasma exchanges (PEs) with albutein 5% as a replacement solution during an intensive treatment phase of two PEs per week over 3 weeks followed by maintenance treatment phase of weekly PE for 21 weeks. The dose of albutein 5% for replacement following plasma removal was calculated based on gender, weight, and the hematocrit of the participant.

Outcomes

Primary Outcome Measures

Change From Baseline in the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) Score

The ALSFRS-R includes 12 questions to assess the self-sufficiency of participants in 3 sub-domains: bulbar function (questions 1-3), fine and gross motor function (questions 4-9), and respiratory function (question 10-12). Aspects of nourishment, personal care, personal autonomy, and communication were also evaluated. Each task was graded on a five-point scale from 0 (incapable) to 4 (normal ability), with total score range from 0 (worst) to 48 (best). A positive change from Baseline indicates improvement.

Change From Baseline in Percent Predicted Forced Vital Capacity (FVC)

The FVC measured the volume of air that can forcibly be exhaled through a spirometer after a full inspiration. It was expressed in a percentage of actual FVC over the expected FVC result in the general population, calculated as: Percent predicted FVC (in %) = [(observed FVC in liters)/(predicted FVC in liters)]*100.

Secondary Outcome Measures

Change From Baseline in Cognitive Function as Assessed by Behaviour Status Sub-scale Score of the Amyotrophic Lateral Sclerosis - Cognitive Behavioural Screen (ALS-CBS) Test

ALS-CBS test is composed of two sections: the cognitive screening section and behavioural changes section. The section of behavioural changes consists of behaviour status and symptom status sub-scales. Behaviour status sub-scale consists of a questionnaire with 15 items assessed by the caretaker. Each item was scored on a scale ranging from 0 (worst) to 3 (best) yielding a total 0= large changes to 45= no changes. A positive change from Baseline indicates improvement.

Change From Baseline in Cognitive Function as Assessed by Symptom Status Sub-scale Score of the Amyotrophic Lateral Sclerosis - Cognitive Behavioral Screen (ALS-CBS) Test

ALS-CBS test is composed of two sections: cognitive screening section and behavioural changes section. The section of behavioural changes consists of behaviour status and symptom status sub-scales. Cognitive function assessed by symptom status sub-scale is reported, which consists of 4 additional questions related to current behavioural 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 subscale score between 0 and 4. A positive change from Baseline indicates improvement.

Change From Baseline in Cognitive Function as Assessed by Cognitive Screening Section Score of the Amyotrophic Lateral Sclerosis - Cognitive Behavioral Screen (ALS-CBS) Test

ALS-CBS test is composed of two sections: cognitive screening section and behavioural changes section. Cognitive function is evaluated using cognitive screening section which consists of: attention (complex orders, mental sums, language, and eye movement); concentration (inversion of numeric series); follow-up and monitoring (reverse sequences, alphabet, number and letter sequencing); and initiation and recovery (nomination). The individual items were scored from 0-5, and the total score ranges from 0-20, where 0= cognitive impairment, 20= no apparent cognitive impairment. A positive change from baseline indicates improvement.

Change From Baseline in the Motor Evoked Potential in Thenar and Hypothenar Eminence and Anterior Tibialis Muscle Determined by Electromyography (EMG)

Surface EMG was performed to record motor evoked potential in the distal muscles of the upper limbs (thenar and hypothenar eminence) and dorsiflexor muscles of the lower limbs (anterior tibialis) after electrical stimulation on the median, ulnar, and external popliteal sciatic nerve. The data for motor evoked potential (in millivolt [mv]) is reported for thenar muscles of both upper limbs and hypothenar muscle of the upper right limb and anterior tibialis of the both lower limbs.

Evaluation of Quality of Life Using the Amyotrophic Lateral Sclerosis Assessment Questionnaire 40 (ALSA-Q40) Test Dimension Score

The ALS questionnaire consists of 40 items grouped into 5 representative dimensions associated with quality of life. The first four dimensions were: physical mobility (questions 1-10), activities of daily living (questions 11- 20), food and drink (questions 21-23), communication (questions 24-30) and emotional function (questions 31-40), refer to deficits and subsequent disabilities as a result of the disease. The fifth scale (emotional functioning) reflects how the participant 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, always). From raw scores, an index from 0 to 100 is obtained for each dimension, which make comparisons with the other dimensions possible as well as a straightforward interpretation of the results (0 = better state of health as measured by the questionnaire;100 = poorer state of health). A negative change from Baseline indicates improvement.

Change From Baseline in Plasma Human Apolipoprotein Levels

The levels of human Apolipoprotein (ApoE) in plasma were measured by enzyme-linked immunosorbent assay (ELISA).

Change From Baseline in Plasma Cytokine Panel Levels

The plasma cytokine panel includes: transforming growth factor (TGF) beta1, TGF beta2, TGF beta3, interferon (IFN) gamma, interleukins (IL)-1beta, IL-1Ra, IL-6, IL-8, IL-10, IL-12 p70, IL-17A, IFN-γ-inducible protein (IP)-10, human monocyte chemoattractant protein (MCP)-1, macrophage-derived chemokine (MDC), macrophage inflammatory protein (MIP)-1-alpha, MIP-1-beta, tumor necrosis factor (TNF)-alpha, soluble cluster of differentiation (CD) 40 ligand (sCD40L), fractalkine. The level of each of these cytokines are reported as categories. Only categories with values above the level of detection are reported.

Change From Baseline in Cerebrospinal Fluid (CSF) Human Apolipoprotein Levels

The level of each of these cytokines are reported as categories. Only categories with values above the level of detection are reported.

Change From Baseline in Plasma Beta-methylamino-L-alanine (BMAA) Levels

Plasma BMAA levels at baseline and over the course of treatment at each evaluation visit were measured to identify reductions in BMAA levels, which could potentially be correlated with disease progression or a halt in disease progression. Analysis was performed using a Thermo TSQ Quantiva triple-stage quadrupole mass spectrometer.

Change From Cerebrospinal Fluid (CSF) Beta-methylamino-L-alanine (BMAA) Levels

CSF BMAA levels at baseline and over the course of treatment at each evaluation visit were measured to identify reductions in BMAA levels, which could potentially be correlated with disease progression or a halt in disease progression. Analysis was performed using a Thermo TSQ Quantiva triple quadrupole mass spectrometer.

Change From Baseline in Absolute Leukocyte Count

The immune population profile in ALS participants was assessed by flow cytometry following whole blood staining by Western Blot (WB) for the absolute leukocyte count. Absolute leukocyte count (10^3 cells/microliter) was analyzed for neutrophils, lymphocytes, CD14+ monocytes, CD3+CD4+ T cells, CD3+CD8+ T cells, CD19+ B cells and CD56+ natural killer (NK) cells.
