Which Drug Class Segment Dominated the Ankylosing Spondylitis Market?
TNF Inhibitors
The TNF inhibitors segment held a dominant position in the market with a share of approximately 45% in 2024, driven by the growing need for targeted therapies and the demand for symptom relief. THF inhibitors, such as etanercept, adalimumab, and infliximab, suppress the immune system by targeting TNF, thereby reducing inflammation in the joints. As TNF inhibitors directly act on the immune system, they treat a disease from its root cause. They prevent structural damage to the bones and enhance the overall well-being of patients.
IL-17 Inhibitors
The IL-17 inhibitors segment is expected to grow at the fastest CAGR of approximately 12% in the ankylosing spondylitis market during the forecast period. IL-17 inhibitors, such as secukinumab and ixekizumab, block the IL-17A pathway, reducing inflammation in arthritis. Several studies have demonstrated the safety and effectiveness of IL-17 inhibitors. They have also found that IL-17 inhibitors produce favorable response rates compared to other therapeutics.
Emerging Biologic Therapies
The emerging biologic therapies segment is expected to grow in the coming years, due to growing research activities and advancements in genomic technologies. As ankylosing spondylitis is also caused by genetic mutations, novel cell and gene therapies are under development. Researchers have shifted focus to the development of personalized medicines and determining their safety profile.
Why Did the Subcutaneous Segment Dominate the Ankylosing Spondylitis Market?
Subcutaneous
The subcutaneous segment contributed the biggest revenue share of approximately 50% in the market in 2024, due to the development of advanced subcutaneous (s.c.) delivery devices and the administration of drugs directly under the skin. Usually, IL-17 inhibitors (secukinumab) are administered through the s.c. Route. Advanced devices enable patients to self-administer the drug, eliminating the need for skilled professionals. The s.c. Route causes less discomfort and is easier to administer, enhancing patient compliance.
Oral
The oral segment is expected to grow with the highest CAGR of approximately 13% in the ankylosing spondylitis market during the studied years. The oral route is more convenient and reduces adverse effects related to injections. They can be modified to enable sustained release and immediate release based on patients’ conditions. Tofacitinib and Upadacitinib are administered through the oral route for the treatment of AS.
Intravenous
The intravenous segment is expected to grow significantly, due to high bioavailability and faster onset of action. Drugs administered through the intravenous (i.v.) route have shown clinical significance and improvements in signs and symptoms. The i.v. The route eliminates the first-pass metabolism pathway and administers the drug directly into the bloodstream. It transports the drug to different body parts.
How the Moderate Ankylosing Spondylitis Segment Dominated the Ankylosing Spondylitis Market?
The moderate ankylosing spondylitis segment held the largest revenue share of approximately 48% in the market in 2024, due to the faster progression of the disease. During moderate AS, the pain may spread up the spine to the neck. The symptoms of moderate AS are more visible compared to the early stage of AS, allowing healthcare professionals to monitor visible signs of the disease and make effective clinical decisions.
Early-Stage Ankylosing Spondylitis
The early-stage ankylosing spondylitis segment is expected to expand rapidly with a CAGR of approximately 10% in the ankylosing spondylitis market in the coming years. People are becoming more aware of screening and early diagnosis of early-stage AS. Early-stage AS may involve frequent stiffness and pain in the lower back and buttocks. It is usually treated through physical therapy and medications.
Severe/Advanced Ankylosing Spondylitis
The severe/advanced ankylosing spondylitis segment is expected to show lucrative growth. Severe stage results in progressive back stiffness, impaired posture, and breathing difficulties. It is difficult to treat with medications and physical therapy alone. Some patients may need joint repair or replacement surgeries when severe joint damage is present. Treatment relieves stiffness and pain, maintains spinal motion, and prevents further complications.
What Made MRI the Dominant Segment in the Ankylosing Spondylitis Market?
MRI
The MRI segment accounted for the highest revenue share of approximately 40% in the market in 2024, due to the high accuracy of MRI to detect early changes of spondylitis. MRI is more sensitive than CT or plain radiography in detecting inflammatory changes. AI and ML are leveraged in MRI to enhance the accuracy and precision of diagnosis. They also assist healthcare professionals in analyzing imaging data.
Digital Spine Monitoring Tools
The digital spine monitoring tools segment is expected to witness the fastest growth with a CAGR of approximately 13% in the ankylosing spondylitis market over the forecast period. Advances in mobile technologies, electric health, and smartphone applications are being developed to diagnose AS. Smartphone apps and wearable sensors are used for remote monitoring, eliminating the need for visiting healthcare organizations. This also enables healthcare professionals to continuously monitor a patient, providing personalized treatment.
Blood Biomarkers
The blood biomarkers segment is expected to grow at a notable CAGR due to simplicity in diagnostic tests and high affordability. Patients suffering from AS have AS-specific mRNA biomarkers in their whole blood. Numerous in vitro and point-of-care diagnostics are developed to evaluate whole blood and quantify biomarkers from the blood. Ongoing efforts are made to identify novel biomarkers that are involved in disease progression.
Which End-User Segment Led the Ankylosing Spondylitis Market?
Hospitals
The hospitals segment led the market with a share of approximately 45% in the market in 2024, due to favorable infrastructure and the presence of skilled professionals. Hospitals have professionals from various disciplines, providing multidisciplinary expertise to patients. Patients prefer visiting a hospital for AS treatment due to favorable reimbursement policies. Hospitals are involved in clinical trials that benefit patients with innovative treatment before market approval.
Specialty Rheumatology Clinics
The specialty rheumatology clinics segment is expected to show the fastest growth with a CAGR of approximately 12% over the forecast period. Specialty clinics possess skilled professionals to provide personalized treatment and care. They also adopt specialized equipment that focuses on rheumatology for diagnosis and medication, as well as physical medicine and rehabilitation for non-surgical management.
Ambulatory Care Centers
The ambulatory care centers segment is expected to grow in the upcoming years. Ambulatory care centers provide outpatient services for AS. They have skilled professionals and suitable infrastructure for conducting minor or minimally invasive surgeries. Ambulatory care centers focus on pain management, maintaining mobility, and preventing spinal stiffness, enabling patient comfort and well-being.
