A quick-read roundup of 10 late-breaking abstracts from the 2026 MDS Congress, from phase 3 Parkinson disease readouts to long-term data in Huntington disease and Tourette syndrome, with the key results that matter for practice.

The Galassia trial will evaluate the safety and tolerability of intranasal cenegermin in about 60 children with spastic cerebral palsy across Italy.

A phase 2 trial found liposomal mitoxantrone hydrochloride had an acceptable safety profile and a potential trend toward fewer relapses in neuromyelitis optica spectrum disorder.

The phase 2 FENerations1 study is an open-label, single-arm, small-scale study evaluating fenebrutinib dosing in 8 to 12 children and adolescents with relapsing MS.

Updated data from Breakfree-2 study showed that treatment with a single zola-cel infusion achieved NEDA-3 in highly active relapsing multiple sclerosis and led to mostly stable disability in progressive multiple sclerosis.

Data from the real-world, CONFIDENCE study found switching from intravenous to subcutaneous ocrelizumab was well tolerated in patients with relapsing and primary progressive MS.

Open-label extension data showed that disability trends observed with vidofludimus calcium during the double-blind period of the phase 2 CALLIPER trial persisted with continued treatment in progressive MS.

Early phase 1 data in 3 patients suggest CTA313, an allogeneic CD19/BCMA CAR-T, may stabilize disability with a manageable safety profile in progressive MS.
