Brief Summary:
The purpose of this study is to evaluate the long-term safety of intramuscular (IM) administration of Engensis in Participants with Amyotrophic Lateral Sclerosis (ALS) who were previously randomized, received treatment, and completed the Day 180 Visit of Study VMALS-002-2. Safety will be assessed by incidences of treatment-emergent adverse events (TEAEs), treatment emergent serious adverse events (TESAEs), adverse events of special interest (AESIs), and the clinically significant laboratory values. See the table below for additional, exploratory endpoints.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. • To evaluate the long-term safety of intramuscular (IM) injections of Engensis in Participants with Amyotrophic Lateral Sclerosis (ALS) [ Time Frame: Day 0 to Day 365 ]
    • Incidence of adverse events (AE) for Engensis compared to Placebo


Other Outcome Measures:
  1. • To evaluate changes in muscle function following Engensis injections in ALS Participants [ Time Frame: Day 0 to Day 365 ]
    • Changes from Baseline (Study VMALS 002-2 Day 0) in Revised Amyotrophic Lateral Sclerosis Function Rating (ALSFRS-R) scores at Day 365 for Engensis compared to Placebo

  2. • To evaluate muscle strength changes following Engensis injections in ALS Participants [ Time Frame: Day 0 to Day 365 ]
    • Change from Baseline (Study VMALS 002-2 Day 0) in muscle strength assessed bilaterally by Handheld Dynamometry (HHD) in muscles in the upper and lower extremities at Day 365 for Engensis compared to Placebo

  3. • To determine whether IM administration of Engensis has effects on respiratory capacity in ALS Participants [ Time Frame: Day 0 to Day 365 ]
    • Change from Baseline (Study VMALS 002-2 Day 0) in Slow Vital Capacity (SVC) at Day 365 for Engensis compared to Placebo

  4. • To determine whether IM administration of Engensis has effects on respiratory function in ALS Participants [ Time Frame: Day 0 to Day 365 ]
    • Time to tracheostomy for Engensis

  5. • To determine whether IM administration of Engensis has positive effects on survival in ALS Participants [ Time Frame: Day 0 to Day 365 ]
    • Time to all-cause mortality compared to Placebo

  6. • To evaluate Quality of Life improvement following Engensis injections in ALS Participants compared to Placebo [ Time Frame: Day 0 to Day 365 ]
    • Change from Baseline (Day 0) in Quality of Life (QoL) using the Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ; with 40 items, ALSAQ 40) on Day 365 for Engensis compared to Placebo

  7. • To evaluate Patient Reported Outcome improvement following Engensis injections in ALS Participants compared to Placebo [ Time Frame: Day 365 ]
    • Patient Global Impression of Change (PGIC) at Day 365 for Engensis compared to Placebo

  8. • To evaluate Clinician Reported Outcome improvement following Engensis injections in ALS Participants compared to Placebo [ Time Frame: Day 365 ]
    • Clinical Global Impression of Change (CGIC) at Day 365 for Engensis compared to Placebo
