E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Demonstrate that targeting IL-23/17 axis will provide a better clinical response at 24 weeks when compared to a second TNF blocker, after failure of a first TNF blocker in axSpA |
|
E.2.2 | Secondary objectives of the trial |
1- Targeting IL-23/17 axis compared to a second TNF blocker will provide: 1.a- A better clinical response after failure of a first TNF blocker in axSpA at weeks 12 and 52. 1.b- A better maintenance of bDMARDs. 2- To compare tolerance of both strategies. 3- To compare the incremental cost-effectiveness ratio (ICER) of the IL23/17 strategy versus the 2nd TNF-blocker strategy. 4- To compare quality-adjusted life-year (QALY) between both strategies. 5- Investigating whether the pharmacokinetic parameters of TNF blockers (serum trough levels concentrations, specific antibody concentrations) measured at inclusion are predictive of a clinical response at W24. 6- Investigating whether the pharmacokinetic parameters of bDMARDs (serum trough levels concentrations, specific antibody concentrations) are associated with low disease activity. |

E.5 End points |
E.5.1 | Primary end point(s) |
Proportion of axSpA patients with a clinical response ASAS40 at week 24.
The ASAS working group has proposed a measure that has been now used in several trials to measure the efficacy of new products on the symptoms of axSpA. The ASAS Response Criteria (ASAS 40) is defined as an improvement of at least 40% and absolute improvement of at least 10 units on a 0-100 mm scale in at least 3 of the following domains compared to values at inclusion: • Patient global assessment measured on a VAS scale with extremes labelled “none” and “severe.” • Pain assessment represented by the average of total and nocturnal pain scores, both measured on a VAS scale with extremes labelled “no pain” and “most severe pain.” • Function represented by BASFI average of 10 questions regarding ability to perform specific tasks as measured by VAS with extremes labelled “easy” and “impossible.” • Morning stiffness, represented by the average of the last 2 questions on the 6-question BASDAI regarding morning stiffness as measured by VAS: one with extremes labelled “none” and “very severe”; the other marking duration of morning stiffness between “0” and “2 or more hours.” Additionally, absence of deterioration (of at least 20% and absolute change of at least 10 units on a 0– 100 mm scale) in the remaining domain should be documented [29]. |

1a/ Clinical response will also be assessed by the following criteria [22,30]: - ASAS40 response rates at week 12 and 52; - ASAS20 response rates at week 12, 24, and 52; The ASAS20 response is based on the same principle with an improvement of at least 20%. - Partial remission rates at week 12, 24, and 52; Partial remission is defined by values lower than 20/100 in each 4 domains described above. - ASDAS major improvement rates at week 12, 24, and 52; ASDAS major improvement was defined by a variation of ASDAS-CRP≥2.
1b/ Maintenance rate of the bDMARDs will be compared in both strategies at week 12, 24, and 52.
2/ Tolerance of the treatment will be collected actively (specific questions on the different expected outcomes in the CRF) at each visit to the study with a focus on any kind of infection. Moreover, it will ask the patient to note on a booklet any side effects during the treatment to reduce the bias of memorisation. 3/ Medical direct and indirect costs will be compared in both strategies. The incremental cost-effectiveness ratio (ICER) of the IL-23/17 strategy versus the 2nd TNF-blocker strategy is defined as follows : Δ(CoûtIL23/17 – Coût2nd TNF) / Δ(Efficacité IL23/17 – Efficacité2nd TNF), in which direct and indirect costs will be elicited from the payer (national health insurance) perspective, and effectiveness expressed in quality-adjusted life years (QALY) and derived from the EQ-5D-5L using French norms [31]. |
