- ToleDYNAMIC Substudy: Inclusion criteria are those of the main study
Who cannot join
- Participants are excluded from the study if any of the following criteria apply:
- The participant is at risk for or has a persistent chronic, active (including fever higher than 38°C and clinically unstable), or recurring systemic infection, as judged by the Investigator
- For participants initiating OL tolebrutinib in the LTS17043 study: Participants at risk of developing or having reactivation of hepatitis, ie, results at the unblinding visit (RMS) or opt-in visit (PMS) for serological markers for hepatitis B and C viruses indicating acute or chronic infection
- Active alcohol use disorder or a history of alcohol or drug abuse within 1 year prior to the opt-in visit
- Current alcohol intake equal to or exceeding the following at the opt-in visit: more than 2 drinks per day for men and more than 1 drink per day for women
- Abnormal ECG during the opt-in visit considered in the Investigator's judgment to be clinically significant, such as QTcF >500 msec, in the context of this study.

- A bleeding disorder, known platelet dysfunction, abnormal platelet count (<100,000/microliter), history of significant bleeding event or other conditions and planned procedures that may predispose the participant to excessive bleeding during the study, as judged by the Investigator.
- For participants initiating OL tolebrutinib in the LTS17043 study: Confirmed unblinding visit (RMS) or opt-in visit (PMS) alanine aminotransferase (ALT) more than 1.5 × upper limit of normal (ULN) OR aspartate aminotransferase (AST) more than 1.5 × ULN OR alkaline phosphatase more than 2 × ULN (unless caused by non-liver-related disorder or explained by a stable chronic liver disorder) OR total bilirubin more than 1.5 × ULN (unless due to Gilbert syndrome or non-liver-related disorder).
- Acute liver disease, cirrhosis, chronic liver disease (unless considered stable for more than 6 months).
- Participants who developed clinically relevant cardiovascular, hepatic, endocrine, neuropsychiatric or other major systemic disease making implementation of the protocol or interpretation of the trial results difficult or that would put the patient at risk by participating in the trial, as judged by the Investigator.
- The participant is receiving treatment during the study period with drugs not permitted by the study protocol, including potent and moderate inducers of cytochrome P450 (CYP) 3A or potent inhibitors of CYP2C8 hepatic enzymes.

About this study
Official title: An Interventional, Phase 3 Extension Study to Investigate Long-term Safety and Tolerability of Tolebrutinib in Participants With Relapsing Multiple Sclerosis, Primary Progressive Multiple Sclerosis, or Nonrelapsing Secondary Progressive Multiple Sclerosis
This is a Phase 3 extension, global, multicenter study to assess the long-term safety and tolerability of tolebrutinib in adult participants (aged ≥18 years) with RMS, PPMS, or NRSPMS who were previously enrolled in the Phase 2b LTS (LTS16004) or 1 of the 4 Phase 3 tolebrutinib pivotal trials (GEMINI 1 [EFC16033], GEMINI 2 [EFC16034], HERCULES [EFC16645], or PERSEUS [EFC16035]).
SUBSTUDY: ToleDYNAMIC substudy
Read the detailed description
Participants with relapsing MS from the Phase 2b LTS16004 parent study will continue open-label (OL) tolebrutinib.
All participants from the Phase 3 parent studies (EFC16033, EFC16034, EFC16645, and EFC16035) will learn which treatment they received in the parent study:
- If from one of the Phase 3 relapsing MS studies and on teriflunomide, an accelerated elimination procedure or a 3-month washout period is required prior to starting OL tolebrutinib. If on teriflunomide, and benefiting and recommended by the Investigator, the participant may opt to continue teriflunomide outside of the LTS17043 study, if clinically appropriate. If on tolebrutinib, the participant will continue tolebrutinib.
- All participants from one of the Phase 3 progressive MS studies will start OL tolebrutinib.
- If a participant already started OL tolebrutinib in the Phase 3 parent study this will be continued.
- RMS participants who are not eligible for OL tolebrutinib per Health Authority and/or ethics committee decisions on the study conduct (ie, partial hold on initiation of tolebrutinib) will continue their parent study treatment assignment as per their randomization from the parent study.
The treatment duration per participant will be approximately 4 years of OL tolebrutinib.
- Conditions
- Relapsing Multiple Sclerosis, Secondary Progressive Multiple Sclerosis, Progressive Relapsing Multiple Sclerosis
- Being tested
- Tolebrutinib, Placebo, Teriflunomide
- Medical subject headings

If unblinded to teriflunomide parent study treatment assignment, these RMS participants will continue teriflunomide in the LTS17043 study. Receives: Drug: Placebo; Drug: Teriflunomide |
What is being measured
The primary outcome is the main question the study is designed to answer.

Time to onset is defined as a sustained increase from baseline EDSS (pivotal trial) of:
- RMS: ≥1.5 points when the baseline score is 0, ≥1.0 point when the baseline score is 0.5 to ≤5.5 or ≥0.5 point when the baseline score is >5.5
- PPMS: ≥1.0 point when the baseline score is ≤5.5 or ≥0.5 point when the baseline score is >5.5
- NRSPMS: ≥1.0 point when the baseline score is ≤5.0 or ≥0.5 point when the baseline score is >5.0
Measured: From baseline until the End of study approximately 4 years per participant
Annualized Relapse Rate (ARR) for RMS only
ARR during the OL treatment period assessed by confirmed protocol-defined relapses
Measured: From baseline until the End of study approximately 4 years per participant
Number of new and/or enlarging T2-hyperintense lesions per year
Measured: From baseline until the End of study approximately 4 years per participant
Change from baseline in total volume of T2-hyperintense lesions

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs), Adverse Events of Special Interest (AESIs) and AEs leading to permanent study intervention discontinuation (time frame: From baseline until the End of study approximately 4 years per participant). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06372145, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2026.
