DUBLIN – Shares in AC Immune SA were off more than 40% Sept. 23 on news that its tau-directed antibody, semorinemab, which is partnered with Genentech, failed to demonstrate efficacy in a phase II trial in Alzheimer’s disease.
UCB SA, a Belgian company developing an antibody targeting a toxic protein tied to Alzheimer’s disease (AD), said Roche Holding AG has negotiated an exclusive global license to the potential therapy for $120 million up front, plus almost $2 billion in milestone payments following positive proof of concept for the anti-tau candidate, UCB-0107, in AD.
Within the first few minutes of a key opinion leader webinar on Alzheimer's disease sponsored by AC Immune SA, CEO Andrea Pfeifer brought up the decision by Biogen Inc. to file for regulatory approval of amyloid beta targeter aducanumab in early AD, based on results from a subset of patients in the phase III study called Engage.
