Study to Investigate the Long-Term Safety and Efficacy of Cimzia over 4 Years of Continuous Treatment in Patients with axSpA

RAPID-axSpA investigated the long-term safety and efficacy of Cimzia over 4 years of continuous treatment in patients with axial spondyloarthritis (axSpA), including both radiographic and non-radiographic axSpA [Figure 1].1,2,3

The RAPID-axSpA study randomised 325 patients, with 111 patients receiving Cimzia 400mg Q4W, 107 patients receiving Cimzia 200mg Q2W (following loading dose of 400mg at weeks 0, 2 and 4) and 107 patients receiving placebo. The trial was double-blind through to week 24.1,2,3

At week 16 placebo non-responders were re-randomised 1:1 to the Cimzia arms. At week 24 the remaining placebo cohort were re-randomised 1:1 to the Cimzia arms and the trial remained dose-blind. From week 48 to 204 the trial was open label.1,2,3,

Efficacy

Cimzia in RAPID-axSpA: Key Efficacy Trial Data

Primary efficacy endpoints

The primary outcome of RAPID-axSpA was ASAS20 response at week 12.1,2,3

At week 12, a statistically significant higher proportion of patients in the Cimzia 200mg Q2W group (57.7%) and Cimzia 400mg Q4W group (63.6%) achieved an ASAS20 response compared with placebo (38.3%) (p=0.004 and p<0.001, respectively). This difference in ASAS20 response continued through week 24 in both Cimzia treatment groups and was achieved as early as week 1 (p<0.001).1,2,3

ASA20 response at week 20, defined as an improvement of ≥ 20% and ≥ 1 unit on a 0-10 NRS in ≥ 3 of the following: Patient's Global Assessment of Disease Activity, Pain assessment, Function, Inflammation and no deterioration in the remaining area.

At week 204 (NRI), of Cimzia randomised patients, ASAS20 and ASAS40 responses were achieved by 54.1 and 44.0% (NRI) and 83.7 and 68.1% (OC), respectively showing sustained efficacy from week 24.1,2,3

Of the 325 patients randomised, 163 were included in the imaging set. Of these patients, 158 (97%) remained in the study to week 24, 146 (90%) to week 48 and 132 (81%) to week 96.4

  • At week 12, the observed mean change from baseline (SD) in the SPARCC SI joint score was significantly greater for CZP-treated patients than patients given placebo: −4.8 (8.6) for patients treated with CZP (dose combined) compared with −1.6 (7.8) for placebo (p<0.001).4
  • Improvements were seen in the spine for CZP-treated patients, with observed mean change from baseline scores (SD) in the Berlin score at week 12 of −2.9 (4.2) in the CZP-treated group (dose combined) compared with 0.2 (4.8) in the placebo group p<0.001.4
  • Improvements to week 12 with both MRI-outcome measures were maintained through the dose-blind (to week 48) and the open-label (to week 96) trial periods.4
Achievement of MRI remission
  • SI joint remission was achieved by 30 of 57 (52.6%) CZP-randomised patients versus 0 of 26 placebo-randomised patients.v
  • Spinal remission was achieved by 31 of 50 (62.0%) CZP-randomised patients and 3 of 23 (13.0%) placebo-randomised patients.4
  • Of patients with both SI joint and spinal inflammation at baseline, 11/29 (37.9%) CZP patients and 0/11 (0.0%) placebo patients achieved MRI remission of both sites.4

MRI remission rates at week 12 were sustained to week 96 for all patients in the imaging set treated with CZP (i.e., including patients re-randomised from placebo to CZP).4

Articular outcomes

At week 204, total resolution of enthesitis was seen in [Figure 5]:

  • 66% of AS (n=58) and 61% of nr-axSpA (n=46) patients with MASES>0 at baseline.
  • 71% of AS (n=17) and 78% of nr-axSpA (n=18) patients with heel enthesitis at baseline.2

A rapid response to CZP was observed in the alleviation of pain, with clinically relevant improvements observed from day 2 for both dosing regimens compared to placebo [Figure 6].5

Safety profile

Cimzia in RAPID-axSpA: Key Safety Data at Week 24

Treatment Emergent Adverse Events (TEAEs) were similar between all CZP and placebo groups, mostly mild (56.2% CZP vs 48.6% placebo) to moderate (36.1% CZP vs 33.6% placebo) in severity, and generally considered by the investigator as unrelated to study medication. Few serious TEAEs were reported overall (5% CZP vs 4.7% placebo); no deaths were reported.1,2,3

‡Serious infections reported: haemophilus infection and laryngitis.

§High-level term.

¶Serious general disorders and administration site conditions was two cases of non-cardiac chest pain; serious investigation TEAE was one case of gamma-glutamyltransferase increased.

Safety and patient-reported outcomes: 4 year outcomes from RAPID-axSpA

There were no new safety signals identified with the increased exposure to CZP, which was shown to have an acceptable long-term safety profile.2

Conclusion

Cimzia rapidly reduced the signs and symptoms of axSpA, with no new safety signals observed compared to the safety profile of CZP in RA. Similar improvements were observed across CZP dosing regimens, and in AS and nr-axSpA patients. Improvements in clinical and patient-reported outcomes at weeks 24 and 96 were sustained through 4 years of treatment, with no new safety signals.1-6
