AbbVie Initiates Phase 2 Clinical Trial Programs for ABBV-8E12, an Investigational Anti-Tau Antibody, in Early Alzheimer's Disease and Progressive Supranuclear Palsy
NORTH CHICAGO, Ill., Jan. 25, 2017 /PRNewswire/ -- AbbVie (NYSE: ABBV), a global biopharmaceutical company, announced the start of two Phase 2 clinical trial programs to evaluate ABBV-8E12, an investigational anti-tau antibody, in patients with early Alzheimer's disease and progressive supranuclear palsy (PSP). In recognition of the lack of treatment options available to patients with PSP, the U.S. Food and Drug Administration (FDA) granted Fast Track Designation to ABBV-8E12. The FDA and European Medicines Agency (EMA) also granted Orphan Drug Designations to ABBV-8E12 for PSP.1,2
"We see potential in ABBV-8E12 and tau-focused approaches to progressive neurodegenerative diseases, such as early Alzheimer's disease and PSP," said Eric Karran, vice president, Foundational Neuroscience Center, AbbVie. "The initiation of the Phase 2 clinical trial programs and the FDA's Fast Track Designation for PSP signify important steps forward in AbbVie's ongoing commitment to investigating innovative scientific approaches with the hope of bringing new treatment options to patients."
After consultation with the FDA and EMA, AbbVie is beginning the Phase 2 clinical trial programs following completion of pre-clinical studies and a Phase 1 study in patients with PSP, which supported the further development of ABBV-8E12 in PSP and early Alzheimer's disease. Positive results from the Phase 1 study in PSP were recently released at the Clinical Trials on Alzheimer's Disease (CTAD) annual meeting in December 2016.3
The Phase 2 study in early Alzheimer's disease will enroll 400 patients to assess the efficacy and safety of ABBV-8E12 to delay disease progression (NCT02880956).4 The Phase 2 study in PSP will evaluate 180 adults and assess the efficacy and safety of ABBV-8E12 to slow disease progression (NCT02985879).5
According to the FDA, Fast Track Designation is a process designed to facilitate the development, and expedite the review of drugs to treat serious conditions and fill an unmet medical need.6 In the U.S., the FDA Orphan Drug Designation is granted to medicines and biologics that are defined as those intended for the safe and effective treatment, diagnosis or prevention of rare diseases or disorders that affect fewer than 200,000 people in the U.S., or that affect more than 200,000 persons but are not expected to recover the costs of developing and marketing a treatment medicine.7 In the EU, Orphan Designation is granted to therapies aimed at the treatment, prevention or diagnosis of life-threatening diseases that affect no more than five in 10,000 persons in the EU and for which no satisfactory therapy is available. The medicine must also provide significant benefit to those affected by the condition.8
ABBV-8E12, licensed from C2N Diagnostics in 2015, is a humanized antibody being studied to target the tau protein, which is thought to stabilize intracellular structures required for maintenance and transport in neurons. Abnormal accumulation of altered tau protein is a hallmark in a variety of neurodegenerative conditions, where the development of tau pathology strongly correlates with clinical disease progression.9
About Alzheimer's Disease
Alzheimer's disease is a progressive, neurodegenerative disorder affecting approximately 34 million people worldwide with the patient population expected to nearly triple by 2050.10 It is the sixth leading cause of death in the U.S. and there are currently no treatments to prevent or delay disease progression.11
About Progressive Supranuclear Palsy
Progressive supranuclear palsy (also known as Steele-Richardson-Olszewski syndrome) is a progressive neurodegenerative disorder, with an estimated worldwide annual incidence of three to six per 100,000 people; and within the U.S., the disease affects approximately 20,000 individuals.12 The average onset of PSP symptoms typically begins after age 60. The most common features of PSP are loss of balance leading to unexplained falls, blurred vision, problems controlling eye movement and slurred speech. Other nonspecific symptoms of PSP, such as slowed movements or behavioral or cognitive changes, are similar to other brain disorders, particularly Parkinson's disease. For this reason, correct diagnosis of PSP is often delayed. The course of PSP is progressive and may predispose individuals to serious complications, such as choking, pneumonia, head injury and fractures caused by falls. Currently, there are no approved treatments for PSP.12 It is one of more than 20 different neurodegenerative disorders characterized by neurofibrillary degeneration and tau inclusions as a predominant central nervous system lesion.9
