Vivoryon Therapeutics NV said it will conduct an in-depth analysis after reporting top-line data showing the phase IIb European Viviad study testing its oral small molecule, varoglutamstat, in patients with early Alzheimer’s disease missed statistical significance on the primary endpoint measuring changes in cognition over time. Investors, however, opted for a more immediate reaction, sending company shares (Euronext Amsterdam:VVY) plunging 90% March 4, to close at €0.80 (US87 cents)
Galimedix Therapeutics Inc. plans to move its lead compound, GAL-101, into a phase IIa proof-of-concept trial next year, in order to test an intriguing hypothesis associated with certain retinal degeneration conditions. GAL-101 selectively binds misfolded amyloid beta species, and the company believes that this mechanism may benefit patients with the dry form of age-related macular degeneration or with glaucoma.
Investigators have identified structural differences between amyloid-beta (Abeta) aggregates in the postmortem brains of patients with inherited and sporadic Alzheimer's disease (AD), respectively. Moreover, both were different from the aggregates that form when Abeta assembles in vitro.
