The European Committee for Medicinal Products for Human Use (CHMP) has issued a positive opinion for Abbott's Humira (adalimumab) in adults with severe axial spondyloarthritis (axSpA) who have no X-ray evidence of structural damage. Upon final decision from the European Commission, Humira will be the first and only approved medication available for non-radiographic axSpA patients (nr-axSpA).
AxSpA, which includes ankylosing spondylitis (AS) and nr-axSpA, can be a debilitating condition that primarily presents with chronic back pain and stiffness, and can also be accompanied by the presence of arthritis, inflammation in the eye and/or gastrointestinal tract. People with non-radiographic axSpA can have similar signs and symptoms as AS, but do not have X-ray evidence of structural damage. AxSpA is most often seen in younger individuals and can go unrecognized for years.
Humira will be indicated for the treatment of adults with severe axial spondyloarthritis without radiographic evidence of ankylosing spondylitis, but with objective signs of inflammation by elevated c-reactive protein (CRP) and/or MRI who have had an inadequate response to, or are intolerant to non-steroidal anti-inflammatory drugs. Humira is currently indicated for the treatment of adults with severe active ankylosing spondylitis who have had an inadequate response to conventional therapy.
“For people with non-radiographic axial spondyloarthritis, there have been limited treatment options that offer relief for this painful and chronic disease,” said John Leonard, MD, senior vice president, Pharmaceuticals Research and Development, Abbott. “This positive opinion reinforces our ongoing promise to making Humira available to a unique patient population with significant unmet medical need.”
The positive opinion for the nr-axSpA indication was based on clinical data from ABILITY-I, an ongoing multi-country phase III study designed to evaluate the efficacy and safety of Humira in axSpA patients without radiographic evidence of structural damage.
Spondyloarthritis (SpA) is a group of diseases that share common clinical, radiographic and genetic features. SpA can be categorized according to which part of the body is mainly affected – axial or peripheral. The Assessment of SpondyloArthritis international Society (ASAS) developed improved classification criteria for axial and peripheral SpA designed to facilitate identification and classification of people with a spondyloarthritis who share similar manifestations. Criteria for axial SpA incorporate the use of magnetic resonance imaging (MRI), in addition to traditional X-rays, for visualizing sacroiliitis (inflammation of the sacroiliac joint which connects the lower spine and pelvis), one of the hallmarks of axial spondyloarthritis.
Humira is a TNF blocker and should not be administered to patients with known hypersensitivity to Humira or any of its excipients; patients with active tuberculosis (TB) or other severe infection such as sepsis and opportunistic infections; and patients with moderate to severe heart failure (NYHA class III/IV).
