Exploratory Study of Biotelemetry in Amyotrophic Lateral Sclerosis
2018年5月31日 更新者：GlaxoSmithKline
An Exploratory Study to Investigate the Use of Biotelemetry to Identify Markers of Disease Progression in Subjects With Amyotrophic Lateral Sclerosis
Study 201283 is an exploratory, non-controlled, non-drug study in Amyotrophic Lateral Sclerosis (ALS) subjects. This study is being conducted as the first step for developing new meaningful measure(s) which might prove to be more effective than existing measures for monitoring clinical function and disease course in ALS. The objective of this study is to test novel measures of movement/physical activity, heart rate and speech and explore how they measure disease progression by evaluating their relationship to gold standard measures of function. This study will be conducted in two phases. A variable length Pilot Phase to test biotelemetry instruments and algorithms reliability and ease of use/acceptance. Approximately 5 subjects will have at least 1 clinic visit to perform a series of set reference tasks while wearing the accelerometer and electrode. Subjects will also continuously wear the accelerometer and electrode in their routine home-life setting for approximately 3 days after the clinic visit (i.e., home monitoring). Subjects in the Pilot Phase will continue in the study and participate in the Core Study Phase. A 48 week Core Study Phase will be conducted to evaluate how measures of movement/physical activity, speech and Heart Rate Variability (HRV) relate to ALS disease progression. During this phase, a maximum of 25 subjects will be enrolled. Subjects will attend 5 clinic visits to perform gold standard measures of function and perform a series of set reference tasks while wearing the accelerometer and electrode. In between clinic visits, every month subjects will attach the accelerometer and electrode and wear it for approximately 3 days in their home. A telephone contact with the subject will be made by the site at the end of each 3-day home monitoring period.

実験的：Pilot and Core Study Phase
During Pilot phase,subjects will attend clinic at least once to perform a series of set reference tasks while wearing the accelerometer and electrode.
Subjects will also continuously wear the accelerometer and electrode in their routine home-life setting for approximately 3 days after the clinic visit (home monitoring).
During 48 week Core Study, subjects will attend 5 clinic visits to perform gold standard measures of function (ALS Functional Rating Scale-Revised and Forced Vital Capacity) and perform a series of set reference tasks while wearing the accelerometer and electrode.
Subjects will also continuously wear the accelerometer and electrode in their routine home-life setting for approximately 3 days after the clinic visits (home monitoring).
In between clinic visits, subjects will attach the accelerometer and electrode and wear it for approximately 3 days in their home.
A telephone contact with the subject will be made by the site at the end of each 3-day home monitoring period
|
Each subject will be issued one FS and a MAT LifeInsight Hub for use during the study.
At each clinic visit in the Pilot and Core Study Phases, the Faros sensor will be placed on the subject just prior to the defined reference tasks and will be worn on the subject's sternum during completion of the tasks.
The morning after the clinic visit, the subject will re-attach the sensor and wear it for approximately 3 days.
In between visits during the Core Study Phase the subject will wear the FS every month for approximately 3 days to enable data collection on a monthly basis over the 48 week study period.
Movement/physical activity data will be collected by the FS throughout the study.
The Fast Fix electrode patch will be worn with the FS on the subject's sternum according to the same schedule as the FS.
The Fast Fix electrode patch will be replaced by the subject on a daily basis during the 3 day monitoring period.
Subjects will be provided instructions on how to operate and wear the Fast Fix electrode patch.
Subjects will follow simple prompts on a computer screen instructing them to say a series of vowels, words, and paragraphs which will be recorded using a high definition digital microphone and stored securely on a laptop.
The speech waveform data will be sent via secure method to GSK/MAT for processing.
