January 4, 2026 updated by: Lingli Dong

Efficacy and Safety of Xeligekimab in the Treatment of Non-Radiographic Axial Spondyloarthritis: A Single-Center, Single-Arm Study

Subjects who have signed the informed consent form will undergo examinations and assessments according to the inclusion/exclusion criteria specified in the trial protocol. After screening and successful enrollment, they will enter the treatment period. Dosing time points are (W0, W2, W4, W8, W12), with a subcutaneous injection of Xeligekimab 100mg each time. Week 12 is the last dosing time. After week 12, the physician will comprehensively assess whether to continue using Xeligekimab based on the patient's condition. If continuation is required, the patient will need to purchase Xeligekimab at their own expense.

During the trial, the research physician and nurse will monitor safety, record the subject's vital signs and adverse events after dosing. Laboratory tests will be performed before and after the trial.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Xeligekimab treatment
Through the subcutaneous administration of Xeligekimab, it is hoped to achieve the control of symptoms and inflammation in nr-axSpA, prevent or delay structural damage, and maximize patients' quality of life.
Drug: Xeligekimab injection

Subjects who have signed the informed consent form will undergo examinations and assessments according to the inclusion/exclusion criteria specified in the trial protocol. After screening and successful enrollment, they will enter the treatment period. Dosing time points are (W0, W2, W4, W8, W12), with a subcutaneous injection of Xeligekimab 100mg each time. Week 12 is the last dosing time. After week 12, the physician will comprehensively assess whether to continue using Xeligekimab based on the patient's condition.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Proportion of participants achieving ASAS20 (ankylosing spondylitis disease activity score) at week 12
Time Frame: at the 12th week after administration

ASAS20 response is defined as an improvement of

20% and an absolute improvement from baseline of 2 units on a 10-point scale in at least three of the four main domains and no worsening assessed at all in the remaining domain.

Main ASAS domains:

Patient's global assessment of disease activity measured on a VAS scale Patient's assessment of back pain, represented by either total or nocturnal pain scores, both measured on a VAS scale Function represented by BASFI average of 10 questions regarding ability to perform specific tasks as measured by VAS scale Inflammation represented by mean duration and severity of morning stiffness, represented by the average of the last 2 questions on the 6-question BASDAI as measured by VAS scale
at the 12th week after administration

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The proportion of overall participants achieving an ASAS40 response at week 12.

Time Frame: week 12
The BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) consists of a 0 through 10 scale (0 being no problem and 10 being the worst problem, captured as a continuous VAS), which is used to answer 6 questions pertaining to the 5 major symptoms of AS.
week 12
The change from baseline in total Bath Ankylosing Spondylitis Functional Index (BASFI).
