Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy, Efficacy

The primary objective of this study is to assess the efficacy of Triumeq versus placebo on overall survival, defined as death from any cause, in participants with ALS at 24 months or after a minimum of 212 events.

Secondary objectives 10

  1. To assess the effect of Triumeq versus placebo on a combined assessment of survival and measures of daily functioning (CAFS)
  2. To assess the effect of Triumeq versus placebo on measures of daily functioning
  3. To assess the effect of Triumeq versus placebo on respiratory function
  4. To assess the effect of Triumeq versus placebo on plasma creatinine
  5. To assess the effect of Triumeq versus placebo on the time to reach advanced disease stages
  6. To evaluate the safety of Triumeq administered orally to participants with ALS
  7. To evaluate the tolerability of Triumeq administered orally to participants with ALS
  8. To assess the effect of Triumeq versus placebo on change in cognitive functioning
  9. To assess the effect of Triumeq versus placebo on change in quality of life
  10. To collect research blood and urine samples for post-trial explanatory analyses; markers will be included e.g. urinary P75ECD, plasma neurofilament light and heavy chain, HERV-K and genotyping

  7. Presence of Hepatitis B core or surface antigen at screening
  8. Participation in any other investigational drug trial or using investigational drug within 30 days prior to screening
  9. Use of NIV ≥22 h per day or having a tracheostomy

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. The primary endpoint is overall survival, defined as time to mortality from any cause

Secondary endpoints 10

  1. Combined assessment of survival and measures of daily functioning using the ALSFRS-R(30) total score (CAFS)
  2. Daily functioning using the ALSFRS-R(30) total score
  3. Respiratory function measured by vital capacity (VC) (% predicted of normal according to the GLI-2012 reference standard(37))
  4. Plasma creatinine levels
  5. Clinical disease stage, defined as mean time spent in each stage of the King’s Staging Scale and the ALS Milano-Torino staging systems (36) (MITOS, derived from ALSFRS-R(30))
  6. Safety based on the safety assessments including physical examinations, clinical laboratory evaluations, vital signs and frequency of adverse events (AEs) or serious adverse events (SAEs). (S)A Es will be categorized according seriousness, causality (by study medication), severity and expectedness (as defined in the Triumeq Summary of Product Characteristics)
  7. Tolerabilty, as defined by study medication discontinuation
  8. Cognitive function, defined as the total scores on the ECAS(32)
  9. Quality of life, defined as total scores on the Visual Analogue Scale (single-item scale) and EQ-5D-5L(35)
  10. Laboratory parameters e.g. Urine P75ECD, plasma neurofilament light and heavy chain, HERV-K expression and genotyping (UNC13a / C9orf72)
