Is this trial a fit for you?
✓Likely a good fit
Adults aged 18-70 with a diagnosis of PPMS or non-active SPMS and evidence of ongoing disease progression.
✕Probably not a fit
Patients with active relapse, certain cardiovascular or infectious conditions, or those needing prohibited concomitant therapies may not benefit.

What this trial studies
This is a randomized, double-blind, placebo-controlled Phase 2a study to evaluate SUN-627 at two dose levels in adults with non-active SPMS or PPMS. The study will assess safety, tolerability, pharmacokinetics, pharmacodynamics, and effects on CNS neuroinflammation. Participants must be 18-70 years old, have PPMS or non-active SPMS, no relapses in 2 years, and documented progression. Exclusion criteria include certain cardiac conditions, active infections, and recent participation in another trial. The study is led by Sundance Biosciences and conducted at three sites in Tampa, Atlanta, and Stony Brook.
Why it matters
Potential benefit: If successful, SUN-627 could offer a new treatment option that may help stabilize or slow disease-related changes in non-active SPMS/PPMS.
How similar studies have gone: Previous similar approaches in neuroinflammatory MS have shown safety signals in early phases, but this exact SUN-627 approach in non-active PPMS/SPMS is exploratory.
