vTv (Nasdaq:VTVT) today announced that results from Part A of the Company’s Phase 3 STEADFAST study of the investigational medication azeliragon in people with mild Alzheimer’s disease did not meet either co-primary efficacy endpoint. Patients taking azeliragon compared with placebo did not improve in cognitive or functional outcomes as measured by the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) and the Clinical Dementia Rating Scale Sum of Boxes (CDR-sb).
vTv Therapeutics is discontinuing current clinical studies involving azeliragon, including the open-label extension study and Part B of the STEADFAST study. Given the progress to date of STEADFAST Part B, the company expects that a substantial portion of the patients in Part B of STEADFAST will have completed 12 months of treatment under the study protocol. vTv Therapeutics will continue to thoroughly evaluate subset data from Part A and then the dataset from Part B over the coming weeks.
“We will continue to analyze the datasets and trends within subgroups from both Part A and Part B to determine if there are potential benefits or future uses and applications for azeliragon,” said Steve Holcombe, chief executive officer, vTv Therapeutics. “On behalf of vTv Therapeutics, we’d like to extend our most sincere and heartfelt gratitude to study participants, their families, physicians and caregivers for their commitment to this important study.”
As of this writing, vTv share price had fallen over 60% in after hours trading.
