New MS pill aims to slash relapses in major trial
NCT ID NCT05201638
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 study tests an oral medication called IMU-838 against a placebo in about 1,100 adults with relapsing multiple sclerosis (MS). The goal is to see if the drug can reduce the number of relapses and new brain lesions over 72 weeks. Participants must be 18-55 years old with active disease, defined by recent relapses.
Why investors are watching
Immunic, Inc. is a very small publicly traded company, and its subsidiary ImmunIC AG is running a Phase 3 trial called ENSURE-2. The trial tests the drug IMU-838 against a placebo in about 1,100 adults with relapsing multiple sclerosis, aiming to see if the drug controls the disease. For a company this size, this late-stage readout is a major event because the result will largely determine the drug's future and the company's prospects.
If it works: If the trial shows IMU-838 works and is safe, the company could move closer to seeking regulatory approval for the drug. That positive result could make the drug a viable treatment option for people with relapsing multiple sclerosis.
If it fails: If the trial fails or is delayed, the drug may not reach the market, which would be a serious setback for a company of this size. Clinical trials often fail, so investors should expect that outcome as a real possibility.
