Inclusion criteria

  1. Female and male patients at least 18 years of age at the time of screening.
  2. Diagnosis of axial spondyloarthritis according to Ankylosing Spondylo Arthritis International Society (ASAS) axial spondyloarthritis criteria
  3. Objective signs of inflammation (magnetic resonance imaging (MRI) or abnormal C-reactive protein)
  4. Total back pain as measured by NRS ≥ 4 at baseline

Exclusion criteria

Exclusion Criteria:

  1. Patients with other uncontrolled active inflammatory diseases.
  2. Clinical laboratory tests and other tests that reveal abnormalities with clinical significance
  3. Patients who have active , or infections as determined by positive results at Screening.
  4. History of cancer.
  5. Known or suspected history of .
  6. Known with allergic or intolerant to mometasone furoate spray or 608/placebo.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. 1. The Percentage of Participants Who Achieved an Assessment of Spondylo Arthritis International Society (ASAS) 40 Response

    Assessment of Spondylo Arthritis International Society criteria (ASAS) consist of 6 domains (4 main and 2 additional assessment domains): 1. Patient's global assessment measured on a NRS; 2. Patient's assessment of back pain, measured on a NRS; 3. Function represented by Bath Ankylosing Spondylitis Functional Index (BASFI) average of 10 questions as measured by NRS; 4. Inflammation represented by mean duration and severity of morning stiffness, on the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) as measured by NRS; 5. Spinal mobility represented by the Bath Ankylosing Spondylitis Metrology Index (BASMI) lateral spinal flexion assessment; 6. C-reactive protein (acute phase reactant). ASAS40 response is defined as an improvement of ≥40% and ≥2 units on a scale of 10 in at least three of the four ASAS main domains and no worsening at all in the remaining domain. A higher score on the NRS signifies higher severity.

    Time frame: From Baseline to Week 16

Secondary outcomes

  1. 2. The Percentage of Participants Who Achieved an Assessment of Spondylo Arthritis International Society (ASAS) 20 Response

    Assessment of Spondylo Arthritis International Society criteria (ASAS) consist of 6 domains (4 main and 2 additional assessment domains): 1. Patient's global assessment measured on a NRS; 2. Patient's assessment of back pain, measured on a NRS; 3. Function represented by Bath Ankylosing Spondylitis Functional Index (BASFI) average of 10 questions as measured by NRS; 4. Inflammation represented by mean duration and severity of morning stiffness, on the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) as measured by NRS; 5. Spinal mobility represented by the Bath Ankylosing Spondylitis Metrology Index (BASMI) lateral spinal flexion assessment; 6. C-reactive protein (acute phase reactant). ASAS 20 response is defined as an improvement of ≥20% and ≥1 unit on a scale of 10 in at least three of the four main domains and no worsening of ≥20% and ≥1 unit on a scale of 10 in the remaining domain. A higher score on the NRS signifies higher severity.

    Time frame: From Baseline to the Week 16
