Amgen, Novartis and Banner Alzheimer’s Institute have announced the collective decision to discontinue investigation of the BACE1 inhibitor CNP520 (umibecestat) in two pivotal Phase 2/3 studies in the Alzheimer’s Prevention Initiative Generation Program. An assessment of unblinded data during a regular pre-planned review identified worsening in some measures of cognitive function. The sponsors concluded that the potential benefit for participants in the studies did not outweigh the risk.
The Generation Program was designed to research the safety and efficacy of CNP520 for the prevention or delay of the onset of Alzheimer’s disease in people at high risk for developing symptoms based on age and their genetic status.
Investigators are being informed of the decision and will be contacting their study participants to discontinue the investigational treatment and discuss next steps, including follow-up appointments as appropriate.
Alzheimer’s is a complex disease and one of the largest challenges facing healthcare today. The Generation Program sponsors are grateful to the study participants, their study partners, and the medical community who took part in the Generation Program and made important contributions to advancing Alzheimer’s research.
Our team joins the millions whose lives are impacted by Alzheimer’s disease in our disappointment that the Generation Program did not yield a treatment for Alzheimer’s disease prevention. We still believe amyloid plays an important but complex role in Alzheimer’s disease. Although the outcomes of the research program did not lead to the results we aimed for, we are committed to sharing our findings to help advance the medical and scientific community one step further toward finding a prevention for this devastating disease,
said David Reese, M.D.,
executive vice president of Research and Development at Amgen.
The study sponsors intend to gain a better understanding of the Generation Program’s data upon further analysis.
