Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Drug: Riluzole Oral Soluble film (ROSF) 50 mg Phase 2

Detailed Description:

This was a single site, single dose, open-label study with one group of male or female patients between 18-80 years old with a diagnosis of Probable or Definite Amyotrophic Lateral Sclerosis (ALS) according to revised El-Escorial Criteria. Patients seen in the ALS Clinic at the University of Florida were screened to determine eligibility for participation in the study according to the specified inclusion/exclusion criteria. Following informed consent and enrollment, subjects were given a complete physical and neurological examination including the validated Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Swallowing safety was assessed using the gold standard Videofluoroscopic Swallowing Study (VFSS) to allow direct visualization of the swallowing process and any episodes of penetration or aspiration were quantified using the validated Penetration Aspiration Scale (PAS). Subjects participated in a standardized protocol that includes 11 bolus stimuli presentations of different liquid and food materials to test swallowing function using a progression of textures and materials. Immediately following this assessment, subjects were given a single dose of ROSF 50 mg, placed on the median lingual sulcus of the dorsum of the tongue (area under the tongue on the midline groove that separates the surface of the tongue into right and left halves). Three minutes after the administration of ROSF, the identical standardized VFSS protocol was re-administered to allow a comparison of swallowing safety (using the PAS scale) pre- versus post-ROSF administration.

The original plan was to enroll 30 patients for a final sample size of 25 completed patients. The protocol stipulated that, depending upon the study enrollment rate, the Sponsor could elect to perform an interim analysis using available data from the subset of subjects who had completed the study at that time. An interim assessment of the data was performed after 8 subjects had completed the study and a ninth patient had been screened and was awaiting VFSS. With agreement from the FDA, the Sponsor decided to terminate the study after 9 completed patients, based on the analysis of the first 8 completed patients showing no evidence of a harmful effect of one dose of ROSF 50 mg on swallowing function.

Arm Intervention/treatment
Experimental: Subjects with ALS
Subjects with a diagnosis of probable or definite ALS in accordance with the Revised El-Escorial Criteria were administered a single dose of the Riluzole Oral Soluble Film (ROSF) 50 mg.
Drug: Riluzole Oral Soluble film (ROSF) 50 mg
Enrolled subjects underwent an instrumental evaluation of swallowing safety before and after administration of a single dose of the ROSF formulation containing 50 mg of riluzole.
Other Names:
  • ROSF
  • Riluzole Orodispersible Film (ROF)




Primary Outcome Measures :
  1. Number of Participants Categorized by Differences From Baseline in Penetration Aspiration Scale (PAS) - Sum of Scores Method [ Time Frame: Before and after administration of ROSF 50 mg on day 1 (visit 1) ]
    Swallowing safety was assessed using the gold standard Videofluoroscopic Swallowing Study (VFSS) to allow direct visualization of the swallowing process and any episodes of penetration or aspiration were quantified using the validated Penetration Aspiration Scale (PAS). The PAS is an 8-point validated scale of swallowing safety that takes into account both degree/level of airway invasion during swallowing and the patients' response to the penetration or aspiration episode. The assessment is performed via videofluoroscope. Scores of 1 and 2 indicate airway safe swallowing with no airway invasion or ability to clear airway invasion. Scores 3 through 8 indicate airway unsafe swallowing based on penetration of the airway, level of penetration, and the patient's ability to respond. An increase in score/higher score means a worse outcome. A decrease in score/lower score means a better outcome.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Male or female subjects between 18-80 years of age, inclusive
  2. Subjects with a diagnosis of probable or definite ALS in accordance with the Revised El-Escorial Criteria
  3. Subjects must be 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.
  4. Subjects with no known allergy to barium, riluzole or inactive ingredients in ROSF
  5. Subject or subject's legally authorized representative must be willing and able to give informed consent/assent and HIPAA authorization.
  6. Subject must have the ability to comprehend and be informed of the nature of the study, as assessed by the Principal Investigator or Sub-Investigator.
  7. Subjects prescribed riluzole at or before the dose of study drug. (The study was open to subjects currently taking riluzole at screening, subjects who were not currently taking riluzole at screening who had taken riluzole in the past, and subjects to be newly started on riluzole (given as ROSF in this study).
  8. Availability to volunteer for the entire study duration and willing to adhere to all protocol requirements
  9. Female subjects of childbearing potential (i.e. not surgically sterile, not 2 years postmenopausal, or not with a sterile partner) must have a negative pregnancy test at Screening and Visit 1, agree to abstinence, be practicing double barrier contraception or using an FDA approved barrier method contraceptive (e.g., licensed hormonal or barrier methods) for more than 2 months prior to the screening visit and commit to an acceptable form of birth control for the duration of the study and for 30 days after participation in the study.

Exclusion Criteria:

  1. Subjects who score 2 or below on the Functional Oral Intake Scale.
  2. Subjects with a prior swallowing study that has shown a Penetration Aspiration Scale score of 3 or greater
  3. Subjects with a history of 2 or more episodes of aspiration pneumonia requiring hospitalization
  4. Subjects with a history of clinically significant liver disease, renal disease, or any other medical condition judged to be exclusionary by the Investigator
  5. Subjects who were unwilling to sign informed consent or subjects who for any other reason in the judgment of investigator were unable to complete the study
