About this trial
The purpose of this study is to evaluate safety, effect on cramps, function and quality of life of ranolazine versus placebo for the treatment of ALS.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
18 years or older

Trial outcomes
Primary outcomes
Frequency of Treatment-Emergent Adverse Events
Patient report and medical records will be used to document adverse events and severe adverse events. Adverse events and severe adverse events will be assessed by the investigator and reported as needed for safety.
Tolerability of treatment assignment
Tolerability will be measured by percentage of patients who complete the treatment assignment. Dose limiting toxicities will be determined by individual with an adverse event necessitating stopping.
Muscle cramp frequency
Muscle cramp frequency will be measured numerically with a reporting period of 7 days. Changes will be compared from baseline to week 28 utilizing a modified Qualitative, Patient-Centered Assessment of Muscle Cramp Impact and Severity questionnaire.
Muscle cramp severity
Muscle cramp severity will be measured by a score of 1-10 (1 being a very mild muscle cramp and 10 being the most severe cramp you ever experienced). Changes will be compared from baseline to week 28 utilizing a modified Qualitative, Patient-Centered Assessment of Muscle Cramp Impact and Severity questionnaire.
Secondary outcomes
Muscle strength
Change in muscle strength over time as measured by hand grip and hand-held dynamometry (HHD) in pounds.
ALS Functional Rating Scale-Revised (ALSFRS-R)
Change in disease severity over time as measured by the ALS Functional Rating Scale-Revised (ALSFRS-R). Each type of function is scored from 4 (normal) to 0 (no ability), with a maximum total score of 48 and a minimum total score of 0. Patients with higher scores have more physical function.
Forced Vital Capacity (FVC)
Change in respiratory function as measured by Forced Vital Capacity (FVC) in liters.
Serum neurofilament light
Changes in serum neurofilament light measured from baseline to end of treatment assignment. Data will be collected to determine differences between placebo and Ranolazine treatment groups at completion of the study.
