Summary of Changes from Version 1.0 (July 27, 2017) to Version 2.0 (October 18, 2017)  
 
 
Note:  
 
Major changes described in the following table have been made in this document to address 
the following issues: 
• Additional exclusion added to clarify the exclusion for the PAS score applies to 
any previous swallowing studies 
• Additional exclusion added for subjects with a history of two or more episodes of 
aspiration pneumonia requiring hospitalization 
• Modified hepatic function exclusion requirement for subjects currently on 
Riluzole 
• Modified hepatic function exclusion requirement for subjects receiving Riluzole 
for the first time 
• Added description of comprehensive and brief physical examinations and 
comprehensive neurological and brief neurological examinations 
 
 
Few minor changes involving wordsmithing for clarity and consistency, punctuation, and 
correction of typos have also been made but are not included in this table because they are 
not substantive changes. However, they are visible in the tracked-changes version of the

SYNOPSIS 
Title 
A single center study to evaluate the effect of Riluzole Oral Soluble Film 
(ROSF) on swallowing safety in individuals with amyotrophic lateral 
sclerosis.  
Objectives 
The primary objective is to evaluate the effect, if any, of a single 50 mg dose 
of Riluzole Oral Soluble Film (ROSF) on swallowing safety in individuals 
with amyotrophic lateral sclerosis. 
Experimental 
Design  
This is a single site, single dose, open-label safety study. Approximately 
thirty (30) individuals with amyotrophic lateral sclerosis (ALS) will be 
enrolled.  Subjects seen in the ALS Clinic at the University of Florida will be 
screened to determine eligibility according to the specified 
inclusion/exclusion criteria. Following enrollment and informed consent, 
subjects will undergo a clinical evaluation including the validated 
Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-
R). Swallowing safety will be assessed using the gold standard 
Videofluoroscopic Swallowing Study to afford direct visualization of the 
swallowing process and any episodes of penetration or aspiration quantified 
using the validated Penetration Aspiration Scale (PAS). Subjects will 
undergo a standardized protocol that includes 12 bolus stimuli presentations 
of different liquid and food materials to test the swallow across a continuum 
of textures and materials. Immediately following, subjects will be given a 
single dose of riluzole oral soluble film (ROSF) 50mg, placed on the median 
lingual sulcus of the dorsum of the tongue. Three minutes after the 
administration of ROSF, the identical standardized VFSS protocol will be re-
administered to allow a comparison of swallowing safety (using the PAS 
scale) pre vs. post ROSF administration. 
Interventions  ROSF is a new formulation of riluzole 50mg that allows for rapid dissolution 
of the medication through a soluble film placed on the dorsum of the tongue 
along the median lingual sulcus.  
Study 
Duration 
 
Participant 
Duration: 
The anticipated time from study enrollment until completion of data analyses 
is approximately 9 months. 
Total study participant time is expected to be approximately 30 days from 
time of screening to completion of study.

Statistical Analysis  
 
Primary Outcome: 
The primary objective is to assess the effect of the ROSF formulation, if any, on swallowing 
safety in subjects with ALS. The null hypothesis is that there will be no difference between 
the PAS scores (i.e. swallowing safety) obtained before and after administration of the study 
medication. 
The PAS scores obtained in swallow tests during VFSS 1-PAS (before ROSF) and VFSS 2-
PAS (after ROSF) will be compared within each subject with the non-parametric Wilcoxon 
Signed-Rank Test.  Alpha will be set at 0.05, two-tailed.  Analysis across each swallowing 
trial will be performed, providing 12 bolus stimuli trials and approximately 35 swallows and 
PAS scores for each elicited swallow across testing within each participant (across various 
textures and swallowing complexities given that multiple swallows are typically elicited per 
bolus stimuli trial) to ensure a comprehensive exam across a variety of liquid volumes, 
textures and consistencies).

Sample size was determined for a within-person design (repeated measures, same subjects in 
VFSS 1-PAS and VFSS 2-PAS) using G*Power Version 3.1.9.2, assuming a correlation = 
0.6 across the two measurements. A sample size of n=25 would be able to detect at least a 1.0 
point difference (two-tailed), effect size 0.6, in PAS scores from Test 1 and Test 2 with 80% 
power. It is anticipated that approximately 20% of recruited ALS subjects will grossly 
aspirate during VFSS 1-PAS and will not have a VFSS 2-PAS performed (for both safety 
reasons and also because Test 2 would not yield any useful data due to a ceiling effect). 
Therefore enrollment is planned for a total of 30 subjects to account for this potential. 
Depending on the study enrollment rate, the Sponsor may elect to perform an interim 
analysis using available data from the subset of subjects who have completed the study at 
that time.  The results of this interim analysis will be used only for internal planning and 
possibly for sharing with regulatory authorities. The results of the interim analysis will have 
absolutely no influence on the subsequent conduct of the study.

6. 
BACKGROUND AND PHARMACOKINETICS 
Riluzole Oral Soluble Film (ROSF) is being developed by MonoSol Rx as an alternative 
dosage form with an alternate route of administration for the existing FDA-approved riluzole 
product, Rilutek® tablets. The ROSF product contains the active ingredient riluzole 
incorporated into a polymer-based film matrix utilizing MonoSol Rx’s PharmFilm® 
technology. The inactive ingredient composition, the film dimensions, and the manufacturing 
process selected for this drug product are based on the information gained from the 
development of ROSF and other film products produced by MonoSol Rx (ZUPLENZ® 4 mg 
and 8 mg and SUBOXONE® 2 mg/0.5 mg, 4 mg/1 mg, 8 mg/2 mg, and 12 mg/3 mg). 
6.1. 
Rationale 
The proposed indication for ROSF is the treatment of patients with Amyotrophic Lateral 
Sclerosis (ALS), the same as for Rilutek® (riluzole) tablets (US Package Insert; revision 
04/2016). Clinical trials with Rilutek® tablets have shown that the time to tracheostomy or 
death was longer for ALS patients receiving Rilutek® compared to placebo, and there was an 
early increase in survival in patients receiving Rilutek® compared to placebo (Riviere 1998; 
Chen 2016; Watanabe 2015). 
Amyotrophic Lateral Sclerosis (ALS) is a rare neurodegenerative disorder marked by the 
disruption of upper and lower motor neuron function. Riluzole is an FDA approved drug for 
treatment of the motor impairments of this disease and is taken by a sizable proportion of 
ALS patients. Given that dysphagia, or swallowing impairment, occurs in a reported 85% of 
ALS patients at some point during the disease progression, the ability to ingest riluzole 
medications can be compromised. Medications that can be easily administered orally without 
water may improve the quality of life of ALS patients and improve patient care. The riluzole 
oral soluble film may circumvent the potential inability of an ALS patient to swallow the 
tablet form of the medication, because the patient or caregiver need only to place the film on 
the tongue, where the active drug can immediately dissolve into the saliva and be ingested 
with intentional swallowing or during the normal reflex of swallowing, eliminating the need 
for swallowing a tablet with liquid or crushing it into soft food. (Appendix B) Absorption 
primarily occurs through the gastrointestinal tract after swallowing. 
Therefore, the ROSF product has the potential to improve care and decrease daily burden on 
patients and caregivers.  
6.2. 
Mechanism of Action 
The mechanism by which riluzole exerts its therapeutic effects in patients with ALS is 
unknown (Rilutek® tablets, US package insert; revision 04/2016). Riluzole decreases the 
release of glutamate, thereby suppressing excitotoxicity. As oxidative stress and

excitotoxicity are early events in ALS pathogenesis (Harikrishnareddy 2015), glutamate-
mediated excitotoxicity has been postulated to be central to ALS pathogenesis, with motor 
neuron degeneration mediated by corticomotoneuronal hyperexcitability through 
transsynaptic anterograde processes (Eisen, 1992). According to Vucic and colleagues (Vucic 
2013), because riluzole inhibits glutamatergic transmission, it may be expected that riluzole 
could exert modulating effects on the transcranial magnetic stimulation parameters of cortical 
excitability. Such a finding would then provide an objective measure of drug efficacy in 
ALS. However, the modulating effects of riluzole on cortical function in ALS have been 
varied. Specifically, while some studies have reported that riluzole partially normalizes 
cortical excitability (Desiato 1999; Stefan 2001), others have failed to establish any cortical 
modulating effects (Sommer 1999; Caramia 2000). In addition to direct anti-glutamatergic 
activity, riluzole appears to exert modulating effects on Na+ channel function (Cheah 2010). 
Given that increased Na+ channel conductance may contribute to neurodegeneration through 
Ca2+-mediated processes (Stys 2005, 2007), the Na+ channel blockade by riluzole may 
provide an additional neuroprotective mechanism in ALS. Of further relevance, riluzole may 
in part exert its anti-glutamatergic effects by inhibiting Na+ channel conductance and 
reducing glutamate release from presynaptic nerve terminals (Jimonet 1994; Cheah 2010).  
6.3. 
Pharmacokinetics 
According to the Rilutek® US package insert (revision 04/2016), riluzole is well absorbed 
with average absolute oral bioavailability of approximately 60% (CV=30%). Cmax occurred at 
approximately 1.0 hour to 1.5 hours after administration (Le Liboux 1997, 1999). AUC 
values were linearly related to dose over a dose range of 25 mg to 100 mg.  A high fat meal 
decreases absorption, reducing AUC by about 20% and peak blood levels by about 45%. The 
mean elimination half-life of riluzole is 12 hours (CV=35%) after repeated doses. With 
multiple-dose administration, riluzole accumulates in plasma by about twofold, and steady-
state is reached in less than 5 days. Riluzole is 96% bound to plasma proteins over the 
clinical concentration range, mainly to albumin and lipoproteins  
A human pilot bioavailability study (Study 1897) comparing ROSF 50mg with Rilutek® 
tablets 50mg found that the extent of absorption was approximately 14% greater and the rate 
of absorption was approximately 6% lower for the ROSF without water than for an intact 
Rilutek® tablet administered with 240 ml of water. When ROSF was administered with 
240ml of water, the extent of absorption was approximately 9% greater and the rate of 
absorption was approximately 12% lower than for the intact Rilutek® tablet administered 
with 240 ml of water. 
The pilot bioavailability study (Study 1897) was an open-label, randomized, single-dose, 
three-period, four-treatment, four-arm, incomplete crossover study. Sixteen adult, non-
smoking subjects were enrolled, and all provided data valid for pharmacokinetic analysis. 
The four treatments were A: ROSF 50 mg administered without water; B: ROSF 50 mg 
administered with 240 mL water; C: Rilutek® 50 mg intact tablet administered with 240 mL

of water; and D: Rilutek® 50 mg tablet, crushed, and administered with 15 mL applesauce. 
The objective was to compare under fasting conditions the bioavailability of the ROSF 50mg 
administered with or without water to that of the intact Rilutek® 50 mg tablet, administered 
with 240 mL of water, i.e., treatments A and B compared with treatment C.  
For Treatment A (film without water) vs. Treatment C (intact tablet), Treatment A had 
approximate 14% higher extent of absorption of riluzole and an approximate 6% lower rate 
of the absorption of riluzole than Treatment C. The geometric mean T/R ratio for AUC0-t and 
Cmax was 113.70% with 90% CI 98.9-130.7%, and 94.36% with 90% CI 74.3-119.7%, 
respectively. For Treatment B (film with water) vs. Treatment C (intact tablet), Treatment B 
had approximate 9% higher extent of absorption of riluzole and an approximate 12% lower 
rate of the absorption of riluzole than Treatment C. The geometric mean T/R ratio for AUC0-t 
and Cmax was 108.6% with 90% CI 93.4-126.2%, and 88.1% with 90% CI 68.1-114.0 %, 
respectively. 
Of note, in the pilot bioavailability study (Study 1897), inter-subject variability for ROSF 
50mg without water for AUC0-t and AUC0-inf was reported as 25 and 26%, respectively, and 
for Cmax, 38%. In contrast, inter-subject variability for the Rilutek® 50mg administered with 
240 mL water for AUC0-t and AUC0-inf was reported as 39 and 40%, respectively, and for 
Cmax, about 48%. The apparent difference between formulations in inter-subject variability 
remained when this comparison was limited to the eight subjects in Study 1897 who received 
both treatments. Intra-subject variability in pilot bioavailability study (Study 1897) was 
reported as 18 and 19% for AUC0-t and AUC0-inf, respectively, and 32% for Cmax.  
6.4. 
Safety 
The most commonly observed AEs associated with the use of Rilutek® that occurred in at 
least 2% of patients (50mg twice daily) in pooled Clinical Study 1 and 2, and at a higher rate 
than placebo were asthenia, nausea, decreased lung function, hypertension, abdominal pain, 
vomiting arthralgia, dizziness, dry mouth, insomnia, pruritus, tachycardia, flatulence, 
increased cough, peripheral edema, urinary tract infection, circumoral paresthesia, 
somnolence, vertigo, eczema. Of those patients who discontinued due to adverse events, the 
most commonly reported were nausea, abdominal pain, constipation, and ALT elevations.  
The following adverse reactions have been identified during the postmarketing use of 
Rilutek®: Acute hepatitis and icteric toxic hepatitis and renal tubular impairment. 
Riluzole Oral Soluble Film (ROSF) was administered to 16 subjects in pilot bioavailability 
study (Study 1897) that evaluated the bioavailability of a single dose of ROSF 50mg 
compared to a single dose of Rilutek® 50mg. Sixteen (16) subjects experienced a total of 4 
adverse events over the course of the study, all mild in severity. The most common was 
somnolence, occurring in 2 subjects who received the ROSF and 2 subjects who received the 
Rilutek® 5 mg dose (Table 1). There were no AEs in clinical laboratory tests and there were 
no Serious Adverse Events (SAEs), or deaths. All formulations of the test and reference

STUDY OBJECTIVES 
7.1. 
Primary Objectives 
Riluzole is FDA-approved for the treatment of patients with Amyotrophic Lateral Sclerosis 
(ALS). Riluzole extends survival and/or time to tracheostomy. ROSF (MonoSol Rx LLC) is 
a new formulation of riluzole that allows for rapid dissolution and release of active drug in 
the oral cavity. Since circumoral paresthesia and dry mouth have been reported with riluzole 
administered as Rilutek® tablets, the primary objective is to evaluate the effect, if any, of the 
new ROSF formulation on swallowing safety in subjects with ALS.  
STUDY DESIGN 
Approximately 30 subjects with ALS will be enrolled and undergo an instrumental 
evaluation of swallowing safety before and after administration of a single dose of the ROSF 
formulation containing 50mg of riluzole.

Videofluoroscopy Swallow Study (VFSS 1-PAS) 
Subjects will undergo a standardized videofluoroscopic swallowing study (VFSS) for direct 
visualization of the swallowing process and any episodes of penetration or aspiration. The 
VFSS represents the gold standard swallowing exam to directly visualize swallowing and 
specifically aspiration during swallowing. After consent has been verified and screens 
completed, the patient will be seated and will complete a standardized bolus protocol that 
includes 12 bolus trial presentations in the following order: 
1. 5ml thin liquid barium 
2. 5ml thin liquid barium 
3. 5ml thin liquid barium 
4. Regular sip of thin liquid taken from a cup containing 60cc of thin liquid. 
5. Consecutive cup sips of remaining thin liquid barium 
6. Tablespoon of thin honey consistency barium 
7. Tablespoon of thin honey consistency barium 
8. Tablespoon of thin honey consistency barium 
9. Tablespoon of pudding consistency barium. 
10. Tablespoon of pudding consistency barium. 
11. Graham cracker with pudding-thick barium. 
12. 13 mm barium tablet (EZ-Disk) with water.  
A standard ‘bail out’ criteria used on all VFSS protocols in the Swallowing Systems Core 
laboratory will be utilized in this study. This represents a standard provision to avoid 
unnecessary risk to research subjects during VFSS exams and will include cessation of bolus 
presentations during a specific VFSS test (i.e. either VFSS 1 or VFSS 2) on the third episode 
of frank aspiration (material entering the airway below the level of the true vocal folds) or 
residue greater than 75% of either vallecular or pyriform housing that is unable to be cleared 
by the patient with prompting and strategies. The potential for this to occur is factored into 
the targeted enrollment of approximately 30 subjects in an effort to complete 25 subjects for 
the swallowing evaluation consistent with the sample size estimation (Section 13.5.3; 
Power).  
The start time and finish time for the standardized bolus protocol will be recorded for both 
VFSS 1 and VFSS 2.

Immediately following VFSS 1-PAS, the patient will then be administered ROSF on the 
dorsum of tongue along the median lingual sulcus, and the time of administration will be 
recorded (Appendix B). Following a three-minute time interval the investigator will confirm 
that the ROSF has dissolved and VFSS 2-PAS will be performed. If ROSF is not fully 
dissolved at 3 minutes, start of the second VFSS 2-PAS bolus protocol will be delayed until 
investigator confirms that ROSF is fully dissolved. The investigator should record whether or 
not ROSF is fully dissolved at 3 minutes after dosing. In the event that ROSF is not fully 
dissolved at 3 minutes, the investigator will record the time that it is confirmed that ROSF is 
fully dissolved. 
Videofluoroscopy Swallow Study Test 2-PAS (VFSS 2-PAS) 
The identical VFSS standardized bolus protocol exam will be performed provided that the 
subject did not demonstrate frank, gross and observable silent aspiration during VFSS 1-PAS 
and provided that the subject’s PAS score in baseline test is 7 or below. VFSS will be 
performed using a Phillips BV Endura fluoroscopic C-arm unit (GE OEC 8800 Digital 
Mobile C-Arm system type 718074) that is housed within the PI’s laboratory and used 
exclusively for research purposes. Fluoroscopic data will be captured in high resolution at 30 
frames per second and in the lateral field of view using a TIMS Dicom (Version 3.2, TIMS 
Medical, TM, Chelmsford, MA). 
The identical standard patient safety bail out criterion will be enforced in VFSS 2. This 
includes cessation of the specific testing phase on the third episode of frank aspiration or 
residue greater than 75% of either vallecular or pyriform housing that is unable to be cleared 
by the patient with prompting and strategies. Once the study is completed, recordings will be 
saved and digitally backed up for subsequent analyses of the PAS. Although this study is 
specifically investigating swallowing safety, this bailout criterion will still allow the study of 
up to three potential episodes of aspiration so that assessing impact on swallowing safety is 
still feasible while maintaining patient safety.   
Missed Visit 1: When a subject fails to appear for scheduled Visit 1, the site will contact the 
subject. The site will stress the importance of the evaluation and reschedule within the 28-
day window if possible. 
10.2.3. 
Study Medication/Intervention Discontinuation Evaluations/Procedures 
Inclusion in the study is entirely voluntary and subjects may withdraw at any time for any 
reason. Possible reason for withdrawal could include serious adverse events, adverse events, 
and subject’s choice.  Subjects who decide to discontinue the study either after receiving the 
VFSS 1-PAS procedure but before receiving study medication or after receiving study drug 
and before VFSS 2-PAS procedure will be asked to comply with end of study clinical 
laboratory evaluation(s) see Section 10.3.7 Laboratory Evaluations. Subjects who withdraw 
due to an adverse event will be followed, whenever possible, until resolution of the adverse

The comprehensive neurological examination will include (as permitted by the patient’s 
capabilities) cranial nerves 2-12, muscle tone and strength, tendon reflexes and plantar 
response, sensory function (pain, light touch, position, vibration), coordination (finger-nose), 
and gait.  The brief neurological examination will include cranial nerves 2-12, muscle 
strength, tendon reflexes, plantar response, and sensory function (pain, light touch, position, 
vibration).  Other elements may be included depending on symptoms or physical findings 
10.3.6.2. Primary Outcome Variable: Videofluoroscopy Swallow Study – Penetration 
Aspiration Scale (VFSS - (PAS)). 
The primary objective is to evaluate the effect, if any, of the new ROSF formulation on 
swallowing safety in subjects with ALS. The primary outcome is the difference in PAS 
Scores obtained before and after ROSF administration.  
The validated penetration aspiration scale (PAS) is a direct measure of swallowing safety. 
The PAS is an 8-point validated scale of swallow safety that takes into account both 
degree/level of airway invasion during swallowing and the patient’s response to the 
penetration or aspiration episode. The PAS scale is provided in Table 4 (Rosenbek, 1996) 
with VFSS lateral image examples recorded and analyzed from our laboratory to provide 
examples of each type of swallow on the right-hand panel.

10.3.8. 
ALS Functional Rating Scale – Revised (ALSFRS-R) Questionnaire  
The ALSFRS-R is a quickly administered (5 minute) ordinal rating scale (ratings 0-4) used to 
determine subjects’ assessment of their capability and independence in 12 functional 
activities/questions (Cedarbaum, 1999). All 12 activities are relevant in ALS. Initial validity 
was established by documenting that in subjects with ALS, change in ALSFRS-R scores 
correlated with change in strength over time, was closely associated with quality of life 
measures, and predicted survival (Appendix A). The test-retest reliability is greater than 0.88 
for all test items. The advantages of the ALSFRS-R are that the categories are relevant to 
ALS; it is a sensitive and reliable tool for assessing activities of daily living function in 
subjects with ALS; and it is quickly administered. In a recent trial employing the ALSFRS as 
a secondary outcome measure, placebo-treated patients showed a decline of 0.92 units per 
month, with a standard error of 0.08. With appropriate training the ALSFRS-R can be 
administered with high inter-rater reliability and test retest reliability. 
10.3.9. 
 Eating Assessment Tool -10  (EAT-10) 
EAT-10: The Eating Assessment Tool-10, is a validated 10-item patient report scale of 
perceived swallowing impairment (Belafsky et al. 2008).  The EAT-10 uses a 5-point ordinal 
rating scale where a patient rates their perceived degree of impairment for each item from 0 
(no impairment) to 4 (severe impairment) for a total range of scores between 0 (no perceived 
swallowing impairment) to 40 (severe impairment) (Appendix C).  The P.I of this study

recently determined that the EAT-10 was sensitive to identify ALS patients with severe 
dysphagia including aspiration. A Receiver Operating Curve analysis revealed that a cut 
point of 8 on the EAT-10 yielded a sensitivity of 86%, specificity of 72%, likelihood ratio of 
3.1, and negative predictive value of 95.5% for detecting aspiration in ALS (Plowman et al., 
2016). 
10.3.10. 
Functional Oral Intake Scale (FOIS) 
The FOIS is a simple 7 point scale that describes the subject’s functional status with respect 
to oral intake, ranging from 1 (No oral intake) to 7 (Total oral intake with no restrictions) 
(Appendix D) (Crary, 2005). 
10.3.11. 
Subject Adherence Assessments 
Adherence to study requirements and compliance with concomitant medication restrictions 
will be assessed Visit 1 through direct questioning by study personnel.  
10.3.12. 
Physical and Neurological Examination 
Subjects will undergo a comprehensive physical and neurological examination at screening, 
and a brief physical and neurological examination at Visit 1 following the second VFSS.   
The comprehensive physical examination will include complete vital signs, weight, height, 
general appearance, and evaluation of systems: head, ears, eyes, nose, and throat; respiratory; 
abdomen; lymph nodes; spine; skin; cardiovascular; and extremities.  The brief general 
physical examination will include abbreviated vital signs (blood pressure, heart rate, 
respiratory rate), and examination of the cardiovascular and respiratory systems and 
abdomen. Other elements may be included depending on symptoms or physical findings. 
The comprehensive neurological examination will include (as permitted by the patient’s 
capabilities) cranial nerves 2-12, muscle tone and strength, tendon reflexes and plantar 
response, sensory function (pain, light touch, position, vibration), coordination (finger-nose), 
and gait.  The brief neurological examination will include cranial nerves 2-12, muscle 
strength, tendon reflexes, plantar response, and sensory function (pain, light touch, position, 
vibration).  Other elements may be included depending on symptoms or physical findings. 
11. 
SAFETY AND ADVERSE EVENTS 
The PI will carefully monitor each subject throughout the study for possible AEs. All AEs 
will be documented on CRFs designed specifically for this purpose. All AEs will be reported 
whether serious or non-serious.

11.1. 
Adverse Experience Reporting and Follow Up 
Subjects will be instructed to inform clinic personnel of any untoward medical symptoms 
and/or events that may arise during the course of the study.  If an adverse event is 
experienced by a subject, then the subject will be questioned concerning symptoms that may 
have occurred after the administration of the study drug.  The incidence, severity and 
duration of all AEs will be recorded according to the following scale: 
Mild 
Adverse event resulting in discomfort, but not sufficient to cause 
interference in normal daily activities 
Moderate 
Adverse event resulting in discomfort that is sufficient to cause 
interference in daily activities. 
Severe 
Adverse event resulting in discomfort causing an inability to carry out 
normal daily activities 
 
Subjects who withdraw due to an adverse event will be followed whenever possible until 
resolution of the adverse event. It may be appropriate for the subject to return to the site 2 
weeks after the subject is off study to evaluate for resolution of any adverse events and to 
receive further information about options for future clinical care.  The Investigator will 
decide the course of action. 
 
11.2. 
Assessing Relationship to Study Drug 
The Principal Investigator/Sub Investigator will assess the relationship of all adverse 
reactions to the drug, using the following scale: 
 
Probable 
A clinical event, including laboratory test abnormality, with a 
reasonable time sequence to drug administration, unlikely to be 
attributed to concurrent disease or other drugs or chemicals, and which 
follows a clinically reasonable response on withdrawal. 
Possible 
A clinical event, including laboratory test abnormality, with a 
reasonable time sequence to drug administration, but which could also 
be explained by concurrent disease or other drugs or chemicals.  
Information on drug withdrawal may be lacking or unclear. 
Unlikely 
A clinical event, including laboratory test abnormality, with a 
temporal relationship to drug administration which makes a causal 
relationship improbable, and which other drugs, chemicals or 
underlying disease provide plausible explanation.

Unrelated 
This category is applicable to AEs which are judged to be clearly and 
incontrovertibly due to extraneous causes (diseases, environment, etc.) 
and do not meet the criteria for drug relationship listed for the above 
mentioned conditions. 
 
Any AEs, whether serious or non-serious, will be monitored throughout the study and 
followed to resolution, when possible, regardless of whether the subject is still participating 
in the study. Subjects who withdraw due to an adverse event will be followed whenever 
possible until resolution of the adverse event. It may be appropriate for the subject to return 
to the site 2 weeks after the subject is off study to evaluate for resolution of any adverse 
events and to receive further information about options for future clinical care.  The 
Investigator will decide the course of action. 
11.3. 
Procedures for Reporting Adverse Events 
Subjects will be instructed to inform clinic personnel of the AEs that may arise during the 
course of the study.  Treatment of any AEs will be administered under the direction of the 
Investigator. 
All symptoms will be recorded by clinic staff and will be reviewed by the Investigator or 
Sub-Investigator prior to any subsequent dosing. 
When appropriate, medical tests and examinations will be performed to document resolution 
of the event(s). 
Adverse events will be coded into the Preferred Term (PT), classified according to the 
current version of Medical Dictionary for Regulatory Activities (MedDRA) with System 
Organ Classification (SOC) and reported with severity, duration, onset time and relationship 
to study drug and action taken. 
Female subjects of child-bearing potential must have a negative pregnancy test at all visits.  
Following administration of study drug, any known cases of pregnancy in female subjects or 
female partners of male subjects, will be reported until 30 days after the subject completes or 
withdraws from the study.    The pregnancy will be reported immediately by phone and by 
faxing/emailing a completed Pregnancy Report to the Sponsor (or designee) within 24 hours 
of knowledge of the event.  The pregnancy will not be processed as a serious adverse event 
(SAE); however the Investigator will follow the subject until completion of the pregnancy 
and must assess the outcome in the shortest possible time but not more than 30 days after 
completion of pregnancy.  The Investigator should notify the Sponsor (or designee) of the 
pregnancy outcome by submitting a follow-up Pregnancy Report.  If the outcome of the 
pregnancy meets the criteria for immediate classification of an SAE (e.g., spontaneous or 
therapeutic abortion [any congenital anomaly detected in an aborted fetus is to be 
documented] stillbirth, neonatal death, or congenital anomaly), the Investigator will report

STATISTICAL CONSIDERATIONS 
13.1. 
General Design Issues 
This open label, single center, single dose study has been designed to evaluate the effect, if 
any, of ROSF, a new formulation riluzole, on swallowing safety in ALS. The study will be 
performed at single center in Gainesville at the University of Florida.  The anticipated time 
from study enrollment until completion of data analyses is approximately 9 months.  The site 
is anticipated to enroll approximately 3-4 ALS subjects per month for a total of 8 months and 
data analysis of raw PAS scoring is anticipated to be conducted over one month.  The 
inclusion criteria are intended to provide a representative cohort of subjects with ALS who 
are currently on an oral diet and able to take foods and liquids by mouth, equivalent to a 
score of 3 or above on the Functional Oral Intake Scale (Crary, 2005).  Eligibility criteria 
exclude subjects with certain medical conditions, allergies to study drug or females that are 
pregnant or breastfeeding.  
The primary aim of this study is to assess swallowing safety with the new ROSF formulation. 
13.2. 
Outcomes 
13.2.1. 
Primary Outcome:  
The primary objective is to evaluate the effect, if any, of the new ROSF formulation on 
swallowing safety in subjects with ALS. The primary outcome is the within subject 
difference in PAS Scores obtained before and after ROSF administration.  
13.3. 
Sample Size and Accrual 
The estimated sample size for this study is 25 completed subjects. Approximately 30 subjects 
will be enrolled. Participants will be recruited from patients followed in the neuromuscular

program at the University of Florida. Interested participants will be contacted by the 
investigators or their staff and invited to participate. These recruitment strategies will include 
a mechanism by which the subjects can provide their contact information. 
13.4. 
Data Monitoring 
Data Monitoring will be conducted according to Good Clinical Practice and applicable 
government regulations. The investigator agrees to allow monitors access to the clinical 
supplies, dispensing and storage areas, and the clinical files of the study subjects and, if 
requested, agrees to assist the monitors. 
Safety monitoring will include careful assessment and appropriate reporting of adverse 
events. Medical monitoring will include contemporaneous assessment of serious adverse 
events. 
13.5. 
Data Analyses 
13.5.1. 
Penetration Aspiration Scale (PAS) 
Following the examination, each recorded swallow trial will be spliced by bolus trial and 
further by individual swallow and coded for subsequent evaluation. This will include splicing 
and coding of each bolus trial per patient (n=12 per VFSS test). Further, each individual 
swallow within a bolus trial will be analyzed (this can range between 1 to 7 swallows per 
bolus trial). Frame-by-frame analysis at 30 frames per seconds will be utilized. Two 
independent, blinded, and experienced raters from the PI’s laboratory will perform analyses. 
Discrepancies between raters will be flagged and resolved at a consensus meeting and three 
swallows from each evaluation will be repeat rated at random for evaluation of intra-rater 
reliability. 
13.5.2. 
Statistical Analysis 
The within subject difference in PAS scores (before and after ROSF) is the primary outcome 
to assess swallowing safety of ROSF in subjects with amyotrophic lateral sclerosis. Data will 
be analyzed using the non-parametric Wilcoxon Signed-Rank Test. Alpha will be set at 0.05. 
Analysis across each swallowing trial will be performed, providing 12 bolus stimuli trials and 
approximately 35 swallows and PAS scores for each swallow within each participant (across 
various textures and swallowing complexities) to ensure a comprehensive exam across a 
variety of liquid volumes, textures and consistencies).  A sample size of 25 subjects is 
estimated to provide 80% power to detect an intra-subject difference of one point on the PAS 
at the 0.05 level (two-tailed).  Additional details will be provided in the statistical analysis 
plan. 
Depending on the study enrollment rate, the Sponsor may elect to perform an interim 
analysis using available data from the subset of subjects who have completed the study at 
that time.  The results of this interim analysis will be used only for internal planning and

possibly for sharing with regulatory authorities. The results of the interim analysis will have 
absolutely no influence on the subsequent conduct of the study. 
 
Summary Statistics will be provided for the following: 
• Demographic information 
• Type, incidence, and severity of adverse events 
• Physical and neurological examinations including oral examination 
• Vital signs (heart rate, blood pressure, respiration rate, temperature),  
• Clinical laboratory evaluation(s) and urine pregnancy test (females of childbearing 
potential) 
• ALS Functional Rating Scale – Revised (ALSFRS-R) 
• Eating Assessment Tool -10 (EAT-10) 
• Functional Oral Intake Scale (FOIS) 
13.5.3. 
Power  
Sample size for the present study was determined for a within-subject design (repeated 
measures, same subjects in VFSS 1-PAS and VFSS 2-PAS) at power = 80% and alpha = 0.05 
(G*Power Version 3.1.9.2), assuming a correlation = 0.6 across the two measurements. A 
sample size of n=25 would be able to detect at least 1.0 point difference, effect size 0.6, in 
PAS scores between VFSS 1-PAS and VFSS 2-PAS  (before and after ROSF). It is 
anticipated that approximately 20% of recruited ALS subjects will grossly aspirate during 
VFSS 1-PAS and therefore not have a VFSS 2-PAS performed (for both safety reasons and 
also because VFSS 2-PAS would not yield any useful data due to a ceiling effect).  Therefore 
a total of 30 individuals with ALS will be recruited and enrolled to account for this potential.  
The null hypothesis is no difference in the PAS scores before and after administration of the 
study medication (i.e. PAS scores for VFSS 1-PAS and VFSS 2-PAS).

Placement Diagram 
 
 
 
Instructions for Use: 
1. Keep the Riluzole Oral Soluble Film in the foil pouch until ready for use and use it 
right way after it is taken out of the pouch. 
2. Make sure your hands are dry. 
3. Fold the pouch along the dotted line to expose the tear notch.  Tear or cut with 
scissors. 
4.  Put the Riluzole Oral Soluble Film on the center of the top surface of the tongue 
immediately after taking it out of the pouch and close the mouth.  It will dissolve in 
minutes.  Administration with liquid is not necessary. 
5. While the film is dissolving do not chew, talk, swallow the film, or move the film 
from placement. 
6. As the film dissolves swallow your saliva in the normal manner. 
Placement on the top surface 
(Dorsal Aspect of the 
Tongue): 
 
Riluzole Oral Soluble film is 
to be centered on the top 
surface of the tongue, along 
the midline, with the posterior 
edge of the film along the 
posterior edge of the tongue 
as illustrated by the Figure. 
 
Ensure film is completely 
adhered to the lingual surface. 
 
Note: Figure is for illustrative 
purposes and not drawn to 
scale.
