Biogen Presents Positive Early Data from Alzheimer's Study

Read MoreHide Full Article

Last week, Biogen Inc. (BIIB - Free Report) presented positive data from a phase I study (PRIME) on its anti-amyloid treatments in development, aducanumab, at the Clinical Trials on Alzheimer's Disease (CTAD) meeting in San Diego.

Biogen’s share price has slipped 10.5% in the past one month, underperforming a decrease of 6.7% witnessed by the Zacks classified Biomed/Genetics industry.

Coming back to the latest news, PRIME, a randomized, double-blind, placebo-controlled, multiple-dose phase Ib study, is being conducted to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of aducanumab in patients suffering from prodromal or mild AD.

Data presented included interim results from the titration cohort of the placebo-controlled period of the PRIME study as well as data from the first year of the long-term extension (LTE).

Data from the titration cohort revealed that when treated with aducanumab, patients experienced a statistically significant reduction in amyloid plaque in the brain after 54 weeks of treatment in all fixed-dose arms (1, 3, 6 or 10 mg/kg arms). In the LTE, there were no new cases of amyloid-related imaging abnormalities in patients initially randomized to aducanumab 3, 6 or 10 mg/kg, who were treated up to 24 months.

Last month, Eli Lilly and Company (LLY - Free Report) announced that its high-profile investigational Alzheimer’s disease drug, solanezumab, has failed to meet the primary endpoint in a late-stage study. With the failure, Lilly decided to cease the development of solanezumab. Shares of Lilly tanked on the news, casting uncertainties over other Alzheimer’s programs like aducanumab that were based on the beta amyloid hypothesis (Read: Will Lilly's Solanezumab Setback Weigh on Other Alzheimer's Stocks?). Note that beta amyloid, a protein that forms plaques in the brain, plays an important role in Alzheimer's disease.

Biogen’s latest results have rekindled hopes that beta amyloid targeting antibodies may offer an effective treatment for Alzheimer's disease.

Currently, Biogen is conducting two other phase III studies (ENGAGE and EMERGE) on aducanumab for the treatment of early AD.

Last week Lilly and AstraZeneca plc (AZN - Free Report) announced that were expanded their existing collaboration to develop their second treatment for Alzheimer's disease, MEDI1814. MEDI1814, which is in phase I studies, is also an antibody targeting beta amyloid.

Another company that is developing antibody treatments targeting beta amyloid is Roche Holding AG (RHHBY - Free Report) .
