Study Endpoints

Primary Endpoints

Overall Survival Rate at 18 Months
From the date of randomization until the date of death or last follow-up censored at 18 months (548 days)

Overall survival was defined from the date of randomization until the date of death (event) or last known alive date (censored). If the death date was after 18 months, the participant was censored at 18 months (548 days). Participants still alive at or after 18 months were censored at 18 months/ 548 days. All data over the 18-month follow-up period after randomization, and participant survival status at the 18-month follow-up visit for participants who withdrew prematurely from the study for reasons other than death were included.

Percentage of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs)
Baseline up to approximately 3 years
Motor Function Measure
every 6 months

Motor function Measure (MFM) D1+D2 score

The primary outcome measure will be the safety assessment.
Safety assessment will be calculated from the date of enrollment for a maximum of 15 months.

safety criteria will be: * Occurrence of AEs, * Physical examination, * Laboratory tests, * Vital signs and ECG,

The primary outcome will be the measure of the percentage of responders defined as patients with a minimum decrease of 50 % of their maximum neuropathic pain dimension (either pain or dysesthesia) present at baseline.
The mean pain score during the last 7 days of the treatment period will be compared to the mean score of the last 7 days of the screening score period.
Mean change in ALT as assessed by an ANCOVA with the following covariates: treatment, gender, subject and time and a non parametric test (Conover-Salsburg).
Mean change in ALT at V1 (Day15) and V2 (Day 30)
Safety criteria
The primary endpoint of this study will be the cumulative incidence of AE/SAE assessed by ongoing monitoring at week 24 (day 168)

Cumulative incidence of adverse events/serious adverse events (i.e. total number per patient) as assessed by ongoing monitoring.

Secondary Endpoints

Percentage of Participants With Failure Over 18 Months
From randomization to the time of the first event to consider at 18 months (548 days)
Amyotrophic Lateral Sclerosis Functional Rating Scale - Revised (ALSFRS-R)
Inclusion, Month 1, Month 2, Month 3, Month 6, Month 9, Month 12, Month 15 and Month 18
Percentage of Participants With a Global ALS FRS-R Score of <30 or Death

Frequently asked questions about olesoxime

What is olesoxime?

Olesoxime is an investigational small molecule developed by Roche Holding AG (ticker RHHBY) for neurological conditions. It has been studied in amyotrophic lateral sclerosis, chemotherapy-induced peripheral neuropathy, spinal muscular atrophy, and relapsing remitting multiple sclerosis. It is not approved and remains in clinical development.

What is olesoxime used for?

Olesoxime has been studied for amyotrophic lateral sclerosis, chemotherapy-induced peripheral neuropathy, spinal muscular atrophy, and relapsing remitting multiple sclerosis. It is an investigational therapy and has not been approved for any indication. All clinical trials of olesoxime listed to date are completed.

Who makes olesoxime?

Olesoxime is developed by Roche Holding AG, which trades under the ticker RHHBY. Roche is the sponsor of the clinical development program for olesoxime across neurological indications including spinal muscular atrophy and multiple sclerosis.

What phase is olesoxime in?

Olesoxime is in Phase 3 development. The overall program includes completed Phase 1 and Phase 2 trials, and the drug has not been approved by the FDA or any regulatory agency. It remains an investigational therapy for the neurological conditions studied.

What clinical trials is olesoxime in?

Olesoxime has been evaluated in completed trials including NCT02628743, a Phase 2 long-term safety and effectiveness study in spinal muscular atrophy; NCT01302600, a Phase 2 safety and efficacy study in SMA patients aged 3 to 25; NCT01808885, a Phase 1 safety study in relapsing remitting multiple sclerosis; and NCT00876538, a Phase 2 study in chemotherapy-induced peripheral neuropathy.

Is olesoxime the same as TRO19622?

Yes, olesoxime is also known as TRO19622. Both names refer to the same investigational small molecule developed by Roche Holding AG. The alternative designation TRO19622 appears in older trial records and publications.
