Multiple Sclerosis Drug Pipeline: 55 Assets by Phase

How many multiple sclerosis drugs are in each phase of development?

Douglas Insights counts 12 multiple sclerosis candidates in Phase III, 22% of the 55 assets in development; Phase II holds 15 and Phase I holds 28.

Phase I/II candidates sit in the Phase I row and Phase II/III candidates in the Phase II row, so each multiple sclerosis asset appears in exactly one row. The 210 trials still recruiting or running carry 40% of the 526 registered trials in scope.

Which approved multiple sclerosis medicines are still in trials?

10 medicines already on the market are still being tested in multiple sclerosis Phase IV trials; Ocrelizumab has the most, with 57 registered trials.

Post-approval multiple sclerosis trials test new doses, new patient groups and head-to-head comparisons. They set the standard of care that every candidate in development will be measured against, so the paid review profiles each one.

How many multiple sclerosis trials are recruiting patients now?

101 multiple sclerosis trials are recruiting patients and 35 more have not started recruiting yet, out of 526 interventional trials in scope; together they make up 26% of the trial base.

Terminated, suspended and withdrawn multiple sclerosis trials stay in the trial base so that a stalled programme is visible, but a candidate whose only trials stopped is no longer counted as in development.

Which companies lead the multiple sclerosis pipeline?

Hoffmann-La Roche leads the multiple sclerosis pipeline with 5 candidates; the top 5 sponsors hold 27% of the 55 assets, and 42 sponsors run at least one.

Industry sponsors lead 270 of the 526 multiple sclerosis trials (51%); universities, hospitals and public funders lead the rest. A sponsor is credited with an asset when it is the lead sponsor on most of that asset's industry trials.

Which drug types and mechanisms dominate the multiple sclerosis pipeline?

Mechanism and drug-type classification for the 55 multiple sclerosis candidates is done by the research desk asset by asset, each with a cited source, and is published in the paid review together with the white-space map.

What multiple sclerosis trial readouts are coming next?

10 multiple sclerosis candidates in Phase II or later have a registered primary completion date in the next 12 months; the next three are below, each linked to its registry record.

Primary completion is the date a sponsor expects the last patient to finish the main measurement, so data usually follow within months. Dates marked estimated are the sponsor's own forecast on the registry and often move.

How many multiple sclerosis readouts fall in each quarter?

14 multiple sclerosis candidates in Phase II or later reach registered primary completion over the next eight quarters, with the most, 6, due in Q2 2027.

Each candidate is counted once, at its next readout. The paid catalyst calendar names every readout with its trial, sponsor and design, adds filings and regulatory decisions, and runs 24 months ahead.

Which countries host the most multiple sclerosis trials?

United States hosts the most multiple sclerosis trials, with sites in 272 of the 526 studies (52%); trials in scope run in 80 countries in all.

A multinational multiple sclerosis trial is counted once in every country where it has a site, so the shares add up to more than 100%. Country spread shows where sponsors are building the evidence that regulators in each market will ask for.

Where are multiple sclerosis drugs being tested?

272 of the 526 multiple sclerosis trials (52%) have a site in the United States, 241 (46%) in Europe and 47 (8.9%) in China; 37 of the 55 candidates in development are tested in the US.

Each region's trials are the evidence its regulator will review: the FDA in the United States, the EMA (with the MHRA and Swissmedic) in Europe, the NMPA in China and the PMDA in Japan. A multinational multiple sclerosis trial counts once in every region where it has a site, so the shares add up to more than 100%. A candidate tested only outside the US and Europe is often a licensing opportunity for sponsors in those markets.

What has changed in the multiple sclerosis pipeline since the last update?

Since 3 Oct 2026, the multiple sclerosis pipeline count moved by −1 assets to 55, Phase III moved by 0 and the trial base by 0.

How does Douglas Insights count the multiple sclerosis pipeline?

Douglas Insights read 526 interventional trials registered on ClinicalTrials.gov for the conditions "multiple sclerosis" and updated since 3 Oct 2021, then grouped every drug or biologic named in them into 55 unique candidates.

1. Code names, generic names and brand names of the same molecule are merged into one candidate, and every merge is reviewed by the research desk.
2. A candidate counts when it has a trial that is recruiting, running, or completed in the last 24 months, and at least one industry-sponsored trial.
3. Its phase is the highest phase among those trials; placebo, standard-of-care and comparator arms are not candidates.
4. Each figure on this page is drawn from one frozen dataset that passes ten checks before release, and the owner approves every edition.
