Anti-tau therapy Medicines Treatment No effect
why

The primary endpoint was not met: the low dose showed no clinically meaningful benefit and the 3 mg dose showed 32% greater progression than placebo, with more serious adverse events. Less whole-brain volume loss on MRI is a surrogate finding.

iADRS disease-progression ratio at 100 weeks (primary); tau PET, brain volume, adverse events phase 2 trial 327 The disease progression ratio relative to placebo was 0.84 (95% credible interval [CrI], 0.66-1.04) for the ceperognastat 0.75 mg group and 1.32 (CrI, 1.10-1.58) for the ceperognastat 3 mg group, corresponding to 16% less and 32% greater progression, respectively. No benefits were demonstrated for secondary clinical end points JAMA 2026

Anti-tau therapy Medicines Treatment No effect
why

The primary clinical endpoint (CDR-SB) was not met in the overall population. The tau figures are a biomarker outcome, not a clinical one.

CDR-SB (primary); tau PET accumulation phase 2 trial 466 "Slowed the rate of tau accumulation versus placebo in key brain regions by 33%-58%" overall and "by 63%-67%" in the low-tau or APOE4 non-carrier subgroup; "In the overall study population, no beneficial effect of low- or high-dose bepranemab compared with placebo was observed on the primary endpoint"; ADAS-Cog14 decline slowed 21-25% UCB press release (data presented at CTAD 2024) 2024

ADAS-Cog11 showed slower decline, but the co-primary functional endpoint (ADCS-ADL) did not differ and the authors classify the study as negative.

ADCS-ADL and ADAS-Cog11 (co-primary) at week 49 phase 2 trial 272 "At week 49, the semorinemab arm demonstrated a 42.2% reduction (-2.89 points, 95% CI -4.56 to -1.21, p = 0.0008) in decline on the ADAS-Cog11 (coprimary endpoint) relative to the placebo arm"; ADCS-ADL difference -0.83 points (95% CI -3.39 to 1.72, p = 0.52), with no difference on MMSE or CDR-SB Neurology 2023

GLP-1 receptor agonist Medicines Treatment No effect
why

Primary outcome null. One secondary cognitive measure (ADAS-Exec) favoured liraglutide on an unadjusted test; ADCS-ADL and CDR-SB did not.

Cerebral glucose metabolic rate at 52 weeks (primary) phase 2 trial 204 Cerebral glucose metabolism difference -0.17 (95% CI -0.39 to 0.06, p=0.14); CDR-SB -0.06 (95% CI -0.57 to 0.44) Nature Medicine 2026

The trial did not meet its primary endpoint at any of three doses despite sustained target engagement (lower CSF soluble TREM2, higher osteopontin); the most frequent adverse events were MRI changes resembling ARIA.
