Study Description

Brief Summary:

This randomized, double-blind, phase III parallel-group non-inferiority study aimed to investigate the efficacy and safety of prefilled liquid etanercept (Yisaipu) versus lyophilized etanercept powder (Yisaipu) in active ankylosing spondylitis patients.

Condition or disease	Intervention/treatment	Phase
Ankylosing Spondylitis	Drug: prefilled liquid etanercept(Yisaipu); Drug: lyophilized etanercept powder(Yisaipu)	Phase 3

Detailed Description:

The study carried out between March 6, 2014 and July 13, 2015 across multiple medical centers in China enrolled adult active ankylosing spondylitis patients aged between 18 and 65 years. Patients were randomized in a 3:1:1 ratio to receive twice weekly 25 mg prefilled liquid etanercept for totally 24 injections (group I) or once weekly 50 mg prefilled liquid etanercept for totally 48 injections (group II), or 25 mg twice weekly lyophilized etanercept powder for totally 48 injections (group III). The primary efficacy outcome was the proportion of patients who achieved ASAS20 at week 24.

Outcome Measures

Primary Outcome Measures :

1. the proportion of patients who achieved ASAS20 [ Time Frame: at week 24 ]
   Axial SpondyloArthritis international Society (ASAS) ASAS20 was defined as an improvement of at least 20% in at least three of the following four domains: 1) patient global assessment VAS, 2) nocturnal back pain and total back pain VAS, 3) Bath AS Function Index (BASFI) VAS, and 4) inflammation (mean of intensity and duration of morning stiffness components from the an improvement at least one unit relative to baseline VAS score; no worsening in the remaining fourth domain.

Secondary Outcome Measures :

1. the proportion of patients who achieved ASAS40, ASAS partial remission [ Time Frame: at weeks 12 and 24 ]
   Axial SpondyloArthritis international Society (ASAS) ASAS40 was defined as improvement of at least 40% in at least three of the four abovementioned domains and an absolute improvement of at least two versus baseline VAS scores and no worsening versus the baseline in the remaining fourth domain. ASAS partial remission was defined as VAS scores ≤2 in each of the four abovementioned domains.
2. the proportion of patients who achieved ASAS 5/6 [ Time Frame: at weeks 12 and 24 ]
   Axial SpondyloArthritis international Society (ASAS) ASAS 5/6 was defined as an improvement of at least 20% in at least five of the following six domains: 1) C-reactive protein (CRP), and 2) spinalmobility (scoliosis) in addition to the four above mentioned domains
3. the proportion of patients who achieved the ASDAS clinically important and major improvement and inactive disease [ Time Frame: at weeks 12 and 24 ]
4. the proportion of patients who achieved BASDAI50 [ Time Frame: at weeks 12 and 24 ]
   Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) BASDAI50 was defined as a 50% or greater improvement versus the baseline BASDAI.
5. the proportion of patients who achieved improvement in BASDAI [ Time Frame: at weeks 12 and 24 ]
   It was evaluated with a 6-question questionnaire,including: 1) fatigue; 2)spinal pain; 3) pain and swelling of peripheral joints; 4) pain at entheseal sites; 5) severity of morning stiffness and 6) duration of morning stiffness by using a single-item visual analog scale (VAS), with scores ranging from 0-10 cm. After taking the answer of each question out of 10 , the BASDAI score was calculated by formula 0.2 [1+2+3+4+0.5(5+6)].
6. the proportion of patients who achieved improvement in BASFI [ Time Frame: at weeks 12 and 24 ]
   Bath AS Function Index (BASFI)
7. the proportion of patients who achieved improvement in BASMI scores [ Time Frame: at weeks 12 and 24 ]
   The Bath Ankylosing Spondylitis Metrology Index (BASMI) is a combined measure of spinal mobility and hip function.Cervical rotation, tragus-wall distance, lateral lumbar flexion( the distance of the middle fingertip moves on the side of the thigh), anterior lumbar flexion(modified schober) , intermalleolar distance were measured. And according to the measurement result, each score with 0, 1, 2 points was recorded.
8. the proportion of patients who achieved improvement in Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) [ Time Frame: at weeks 12 and 24 ]
   The (MASES) index based on 13 entheses. Enthesial sites assessed include the bilateral 1st costochondral joints(L and R), 7th costochondral joints(L and R), posterior superior iliac spines(L and R), anterior superior iliac spines(L and R), iliac crests(L and R), proximal insertion of Achilles tendons(L and R), and the 5th lumbar spinous process.The score of each part with 0 or 1 points was recorded.
9. the proportion of patients who achieved improvement in nocturnal back pain and total back pain VAS [ Time Frame: at weeks 12 and 24 ]
   Nocturnal back pain and total back pain in the past week was assessed using a single-item visual analog scale (VAS), with scores ranging from 0-10 cm, where 0 represented no pain and 10 represented worst possible pain.
10. the proportion of patients who achieved improvement in patient global assessment and physician global assessment [ Time Frame: at weeks 12 and 24 ]
    Patient global assessment (PGA,disease activity rated by the patient) was recorded on a VAS from 0 to 10 cm, where 0 represented very good and 10 represented very worse. Physician global assessment (PhGA,disease activity rated by the physician) was recorded on a VAS from 0 to 10 cm, where 0 defined as no disease activity state and 10 defined as most serious disease activity state .
11. the proportion of patients who achieved improvement in number of swollen joints and number of tender joints [ Time Frame: at weeks 12 and 24 ]
12. the proportion of patients who achieved improvement in ESR and CRP [ Time Frame: at weeks 12 and 24 ]

Other Outcome Measures:

1. AEs [ Time Frame: at weeks 2, 4, 8, 12, 16, 20 and 24 ]
   To assesse the safety
