Key take away

As per the primary outcomes of this randomized controlled phase III study (PREVENT trial), secukinumab significantly improved disease activity, physical function, quality of life, and objective signs of inflammation in biologic therapy-naive or inadequate reaction to TNF-inhibition in nr-axSpA patients. Both secukinumab routines (LD and NL) had an early and sustained treatment effect through Week 52.

Background

The primary results of PREVENT, the phase III study assessing secukinumab in active nonradiographic axial spondyloarthritis (nraxSpA) patients has been reported in this study.

Method

All in all, 555 patients were randomized to secukinumab 150 mg subcutaneously (SC) with loading (LD), without loading (NL), or placebo weekly and then, every 4 weeks beginning at Week 4. To maintain blinding, the NL group obtained placebo at Weeks 1, 2, and 3. After week 20, change to openlabel secukinumab (OL) or standard of care (SoC) was allowed.


The ASAS40 at Week 16 (LD) and Week 52 (NL) in tumour necrosis factor inhibitor (TNFi)naïve patients was considered as the primary endpoint. All the patients receiving ≥1 dose of study therapy was included in the safety evaluates.

Result

A total of 481 patients finished 52 weeks therapy: 84.3% (156/185) LD, 89.7% (165/184) NL, and 86.0% (160/186) placebo. Percentage of patients who switched to OL or SoC between Weeks 20 and 48 was 50.8% LD, 47.3% NL, and 64.0% placebo (figure 1).

At week 16, both the primary and all secondary endpoints were met. At Week 16, considerably higher ASAS40 in TNFinaïve patients for LD (41.5%) and NL (39.8%) at Week 52 versus placebo was found.

Conclusion

Along with a consistent safety profile, secukinumab 150 mg provided significant and continued improvement in signs and symptoms of nraxSpA patients during 52 weeks.
