Alzheimer’s therapy granted breakthrough designation

Oct. 14, 2021

Roche announced that gantenerumab, an anti-amyloid beta antibody developed for subcutaneous administration, has been granted breakthrough therapy designation by the U.S. Food and Drug Administration (FDA) for the treatment of people living with Alzheimer’s disease.

This designation is based on data showing that gantenerumab significantly reduced brain amyloid plaque, a pathological hallmark of Alzheimer’s disease, in the ongoing SCarlet RoAD and Marguerite RoAD open-label extension trials, as well as other studies. Learnings from these studies have been incorporated into the optimized design of two ongoing parallel, global, placebo-controlled and randomized Phase III trials, GRADUATE 1 and 2. The pivotal trials are evaluating gantenerumab in more than 2,000 participants for more than two years and are expected to be completed in the second half of 2022.

Breakthrough therapy designation is designed to accelerate the development and review of medicines intended to treat serious or life-threatening conditions with preliminary evidence that indicates they may demonstrate a substantial improvement over available therapies that have received full FDA approval.

Gantenerumab is an investigational IgG1 antibody designed to bind to aggregated forms of beta-amyloid and remove brain amyloid plaques, a pathological hallmark of Alzheimer’s disease.
