Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will be asked to consume two study products (placebo and active) during the screening visit. Eligible Subjects who can consume the products will enter the study and commence Run-In, a 14 day period.
During the 14 day Run-In period all subjects will complete a daily telephone questionnaire through an IVRS to document information on the previous day's cramps as well as obtain information on Subjects Spacticity through the measurement of the NRS.
Upon completion of the Run-In, Subjects will be randomised to one of two possible sequences (Control - Active or Active - Control). Subjects will be allocated to each sequence in a one to one ratio. Subjects will be instructed to take study product two times a day, morning and evening.. Each Cross-over Period (Periods 1 and 2) is 14 days. There will be a 7-day Wash-out between Period 1 and Period 2

Subjects will be given additional study product to account for a 3 day window and potential spills/contamination.

Each treatment may include a combination of any of the following:
Component of Ginger
Ethanol alcohol (trace amount)
Lactose
Sucrose
Aspartame
Water

Participants will consume a single oral disintegrating tablet twice daily, morning and evening.

Adherence to the intervention will be monitored via product return.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Each participant will be assigned a unique identification number. Participants who complete study screening assessments and meet all the eligibility criteria will receive corresponding treatment (control, active) according to the randomization schedule at the end of the run in period.

Allocation was concealed by computer randomization scheme developed to assign the subject with corresponding treatment (control, active).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computerized randomisation scheme created by study statistician
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Other design features
50 participants will be recruited and will be randomly allocated to receive orally disintegrating tablets in a crossover manner.
Phase
Phase 1
Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
The sample size chosen for this study was based upon results from three previous Flex studies and was selected without statistical considerations.
As there are multiple endpoints, it is assumed this sample size will be sufficient to provide initial indication of efficacy for the other endpoints.
The following endpoints will be used in the study:


Worsening of the following from baseline:
Pain and Intensity of Cramps;
Insomnia Severity Index (ISI) Survey;
ALS Assessment Questionnaire (ALSAQ);
Numerical Rating Scale (NRS) for spasticity;
Modified Ashworth Scale (MAS);
Tardieu Scale;
Patient Global Impression of Change (PGIC) scale;
Clinical Global Impression (CGI) scale

Safety Endpoints:
Percentage of Subjects with treatment-emergent AEs;
Change in Vital Sign parameters from Screening; and;
Change in laboratory parameters from Screening

The study is exploratory in nature, The efficacy endpoints will be summarised by Treatment Sequence and Period. A paired Wilcoxon signed rank test will be conducted to test for treatment effect at the 5% level of significance. The following descriptive statistics: arithmetic mean (AM), standard deviations (SD), sample size (N), coefficient of variation (CV), median, minimum and maximum values will be calculated for the continuous efficacy endpoints (primary and exploratory) by treatment and time point.
All data will be summarised based on the safety population and data will be presented by Treatment Group within Treatment Sequence and Treatment Group. The actual treatment received will be presented.
