FDA Approves Cimzia (certolizumab pegol) for the Treatment for Non-Radiographic Axial Spondyloarthritis

Brussels, Belgium – 29 March 2019 – UCB, a global biopharmaceutical company, announced today that the U.S. Food and Drug Administration (FDA) has approved extending the label for Cimzia (certolizumab pegol) to include a new indication for the treatment of adults with active non-radiographic axial spondyloarthritis (nr-axSpA) with objective signs of inflammation. The approval makes Cimzia the first and only FDA-approved  treatment for nr-axSpA.

A chronic inflammatory condition, nr-axSpA mainly affects the spine and sacroiliac joints and is often undiagnosed and not appropriately treated. In nr-axSpA, definitive evidence of the disease is not evident on an x-ray. Disease onset typically begins in early adulthood and causes chronic and debilitating back pain, stiffness and fatigue, often having a profound impact on patients’ lives.

“This is such an important advancement for the spondyloarthritis community. More treatment options, earlier diagnosis, and awareness building will lead to better outcomes for people living with the disease,” said Cassie Shafer, Chief Executive Officer, Spondylitis Association of America.

“The FDA approval of Cimzia for adults with non-radiographic axial spondyloarthritis will be transformative for the many patients living with this disease,” said Emmanuel Caeymaex, Head of Immunology and Executive Vice President at UCB. “We are proud to be at the forefront of discovering and delivering valuable treatment options for patients with significant disease burden and high unmet need. We are committed to improving care and outcomes for patients across the axial spondyloarthritis spectrum of disease.”

“Non-radiographic axial spondyloarthritis requires early diagnosis, followed by appropriate treatment. Yet for some patients, the journey to diagnosis can take nearly a decade from symptom onset. This FDA indication will make it easier for patients to receive another avenue of treatment in reducing the severe pain, stiffness, and other burdensome symptoms associated with this disease, to help ultimately improve their quality of life,” said Dr. Atul Deodhar, MD, MRCP, FACP, FACR, Professor of Medicine, Oregon Health & Science University, and a lead author for the pivotal C-AXSPAND study.

This FDA approval is based on data from C-AXSPAND, a Phase 3, multi-center, double-blind, placebo-controlled 52-week study that randomized 317 adult patients to receive either Cimzia or placebo plus common background medications, which included NSAIDs, corticosteroids, analgesics and slow-acting anti-rheumatic drugs.1 The study met its primary endpoint, with 47.2% of patients treated with Cimzia demonstrating major improvement response in Ankylosing Spondylitis Disease Activity Score (ASDAS-MI) at week 52, compared to 7.0% of patients treated with placebo.1 ASDAS-MI is a validated, rigorous response threshold, defined as an ASDAS decrease of at least two points from baseline or reaching the lowest possible value.1 C-AXSPAND is the first study to adopt this stringent threshold as a primary outcome measure. Detailed findings from the study were published online in Arthritis & Rheumatology on March 8, 2019.

The study also met ASAS40, an important secondary endpoint, with 47.8% of Cimzia-treated patients achieving a 40% improvement in Ankylosing Spondylitis Assessment Score (ASAS40) compared to 11.4% of placebo-treated patients at week 12.

The safety profile for patients with nr-axSpA treated with Cimzia was similar to the safety profile seen in patients with RA and previous experience with Cimzia.

According to the updated label, the recommended dose of Cimzia for adult patients with nr-axSpA is 400 mg (given as 2 subcutaneous injections of 200 mg each) initially and at weeks 2 and 4, followed by 200 mg every 2 weeks or 400 mg every 4 weeks.

Cimzia is also FDA-approved for ankylosing spondylitis (AS), as well as rheumatoid arthritis, psoriatic arthritis, plaque psoriasis, and Crohn’s disease.

About Non-Radiographic Axial Spondyloarthritis (nr-axSpA) and Ankylosing Spondylitis (AS)

nr-axSpA and AS comprise the axial spondyloarthritis, or axSpA, spectrum of disease, which typically starts in patients under 45 years of age. nr-axSpA and AS share similar symptomology and disease burden. In AS there is definitive structural damage in the sacroiliac joints detectable by x-ray. In nr-axSpA, there is no definitive radiographic sacroiliitis, though more sensitive magnetic resonance imaging (MRI) testing may detect evidence of active sacroiliitis, visible as inflammation in the sacroiliac joints. Historically, nr-axSpA has not been well-recognized due to a lack of understanding of the disease history, progression, and prognosis, resulting in substantial diagnostic delay.

Patients face a significant disease burden whether they have nr-axSpA (i.e., no definitive evidence of sacroiliitis on x-ray) or AS (i.e., definitive evidence of sacroiliitis on x-ray). They often experience substantial inflammatory back pain, prolonged and severe stiffness, fatigue, sleep disturbances, reduced physical function, decreased quality of life, impaired work and home productivity and social participation.

Limited evidence exists regarding the exact prevalence of axSpA, though it is thought to impact a substantial proportion of the population. Recent data suggest that 0.5% to 1.4% of the adult population have axSpA, similar to the prevalence of rheumatoid arthritis, which is 0.5% to 1.0%.2,3,4  Within the axSpA spectrum of disease, the prevalence is split roughly equally between nr-axSpA and AS.4
 

About C-AXSPAND

C-AXSPAND included adult patients with active axSpA without x-ray evidence of ankylosing spondylitis (AS). Patients needed to have objective evidence of inflammatory disease, defined as sacroiliitis on MRI and/or elevated C-reactive protein (CRP) levels. Patients must have had an inadequate response to, have a contraindication to, or have been intolerant to at least two non-steroidal anti-inflammatory drugs (NSAIDs). Inadequate response to an NSAID is defined as lack of response to at least 14 days of continuous NSAID therapy at the highest tolerated dose of the administered NSAID. Patients in both the treatment and placebo groups remained on their background therapy for the duration of the study, which could be adjusted at any point. Safety variables assessed in the study were adverse events, vital signs, physical examination, and measurements of laboratory parameters. The safety profile was consistent with previous clinical trials of Cimzia.

The primary objective of C-AXSPAND was to assess the safety and efficacy of Cimzia on the signs and symptoms of active axSpA in patients without x-ray evidence of AS. The primary endpoint assessed was ASDAS-MI response at Week 52. The secondary objectives of the study were to assess efficacy, safety, and tolerability, and to demonstrate the effect of Cimzia on health outcomes, disease activity, sacroiliac joints, inflammation through MRI, and changes in concomitant and background medications.

The first 52 weeks of the study have been completed and an additional two years of safety follow-up are ongoing.

About Cimzia

Cimzia is the only Fc-free, PEGylated anti-TNF (Tumor Necrosis Factor). Cimzia has a high affinity for human TNF-alpha, selectively neutralizing the pathophysiological effects of TNF-alpha.


Cimzia is indicated for the treatment of adults with moderately to severely active rheumatoid arthritis (RA), adults with active psoriatic arthritis (PsA), and adults with active ankylosing spondylitis (AS). Cimzia is indicated for the treatment of adults with active non-radiographic axial spondyloarthritis (nr-axSpA) with objective signs of inflammation.

Cimzia is also indicated for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy.

In addition, it is indicated for reducing signs and symptoms of Crohn's disease (CD) and maintaining clinical response in adult patients with moderately to severely active disease who have had an inadequate response to conventional therapy.
