Long-term safety and efficacy of certolizumab pegol in combination with methotrexate in the treatment of rheumatoid arthritis: 5-year results from the RAPID 1 trial and open-label extension.

ABSTRACT:

Objectives

To examine the safety and efficacy of 5-year administration of certolizumab pegol (CZP)+methotrexate (MTX) in patients with active rheumatoid arthritis (RA).

Methods

Eligible patients from the Rheumatoid Arthritis Prevention of Structural Damage (RAPID)1 randomised controlled trial (RCT) were treated in open-label extension (OLE) with CZP 400 mg every other week (Q2W), reduced to 200 mg Q2W after ?6 months, +MTX. Combined safety data from RCT and OLE are presented from initiation of CZP treatment to 12 wks post last visit in patients receiving ?1 dose of CZP (Safety population, N=958). Efficacy data are presented to start of first site closure (wk 256 of CZP treatment: 52 wks in RCT+204 wks in OLE) for all patients randomised to receive CZP (intent-to-treat (ITT) population, N=783) and CZP patients who completed the 52 wk RCT and enrolled into OLE (wk 52 CZP completers, N=508). Disease Activity Score (DAS)28 (Erythrocyte Sedimentation Rate (ESR)), American College of Rheumatology Criteria (ACR) 20/50/70, Health Assessment Questionnaire - Disability Index (HAQ-DI), and patient retention (Kaplan-Meier analysis) were assessed.

Results

Overall event rate per 100 patient-years (ER) of adverse events (AEs) was 290.4, most frequently: urinary tract infections (ER=7.9), nasopharyngitis (ER=7.3) and upper respiratory tract infections (ER=7.3). ER of serious AEs was 20.3 (infections=5.9, malignancies=1.2). 21 patients (2.2%) experienced an AE resulting in death (incidence rate=0.6). At wk 256 of treatment, 55.3% of the CZP ITT population were estimated to remain on treatment (68.7% if solely withdrawals due to AE or lack of efficacy were considered). In wk 52 CZP completers and CZP ITT population, DAS28 (ESR) remission rates and improvements from baseline were sustained to wk 256.

Conclusions

CZP+MTX treatment provided a favourable risk-benefit profile over 5 years in patients with active RA. No new safety signals were identified.

Project description:As patients with rheumatoid arthritis (RA) receive treatment with anti-tumour necrosis factors over several years, it is important to evaluate their long-term safety and efficacy. The objective of this study was to examine the safety and benefits of certolizumab pegol (CZP)+methotrexate (MTX) treatment for almost 5 years in patients with RA.Patients who completed the 24-week Rheumatoid Arthritis Prevention of Structural Damage (RAPID) 2 randomized controlled trial (RCT; NCT00160602), or who were American College of Rheumatology (ACR) 20 non-responders at Week 16, entered the open-label extension (OLE; NCT00160641). After ?6 months treatment with CZP 400 mg every two weeks (Q2W), dose was reduced to 200 mg Q2W, the approved maintenance dose. Safety data are presented from all patients who received ?1 dose CZP (Safety population, n=612). Efficacy data are presented to Week 232 for the intent-to-treat (ITT, n=492) and Week 24 CZP RCT Completer (n=342) populations, and through 192 weeks of dose-reduction for the Dose-reduction population (patients whose CZP dose was reduced to 200 mg, n=369). Radiographic progression (modified total Sharp score change from RCT baseline >0.5) to Week 128 is reported for the Week 24 CZP Completers.In the RCT, 619 patients were randomized to CZP+MTX (n=492) or placebo+MTX (n=127). Overall, 567 patients (91.6%) entered the OLE: 447 CZP and 120 placebo patients. Of all randomized patients, 358 (57.8%) were ongoing at Week 232. Annual drop-out rates during the first four years ranged from 8.4-15.0%. Event rates per 100 patient-years were 163.0 for adverse events (AEs) and 15.7 for serious AEs. Nineteen patients (3.1%) had fatal AEs (incidence rate=0.8). Clinical improvements in the RCT were maintained to Week 232 in the CZP Completers: mean Disease Activity Score 28 (Erythrocyte Sedimentation Rate) change from baseline was -3.4 and ACR20/50/70 responses 68.4%/47.1%/25.1% (non-responder imputation). Similar improvements observed in the ITT were maintained following dose-reduction. 73.2% of CZP Completers had no radiographic progression at Week 128.In patients with active RA despite MTX therapy, CZP was well tolerated, with no new safety signals identified. CZP provided sustained improvements in clinical outcomes for almost 5 years.ClinicalTrials.gov, NCT00160602 and NCT00160641 . Registered 8 September 2005.

Project description:IntroductionPeficitinib is a novel orally bioavailable, once-daily Janus kinase (JAK) inhibitor approved in Japan for the treatment of rheumatoid arthritis (RA). This 2-year extension study of two global phase IIb trials investigated the long-term safety and effectiveness of peficitinib.MethodsAll eligible patients with moderate-to-severe RA including patients in the placebo group who participated in one of two global phase IIb trials ('with methotrexate' or 'without methotrexate') were included in this 2-year open-label extension study and were converted to peficitinib 100 mg once daily. The primary objective was to evaluate an additional 2 years of safety by assessing treatment-emergent adverse events (AEs) and clinical laboratory evaluations for 105 weeks. Evaluation of an additional 2 years of effectiveness using American College of Rheumatology (ACR) 20/50/70 responses was the exploratory objective.ResultsOverall, 611 patients were enrolled in the extension study: 319 (52.2%) patients completed the study and 292 (48%) discontinued treatment, including for withdrawal of patient consent (n = 96), failure to achieve low disease activity (n = 62), and AE not including death (n = 41). AEs were reported in 463 (76%) patients. The most common AEs (per 100 patient-years) were upper respiratory tract infections (9.9) and urinary tract infections (7.2). Serious AEs were reported in 80 (13%) patients, with incidences per 100 patient-years of serious infections 2.7, herpes zoster 1.5 (including one herpes zoster ophthalmic), and malignancies 0.6 (most frequently basal cell carcinoma). At week 105, 269 (44%) patients demonstrated an ACR20 response relative to their respective phase IIb trial baselines.ConclusionAmong 319 patients who completed this 2-year extension of two global phase IIb studies, peficitinib 100 mg once daily demonstrated a stable safety profile and sustained effectiveness in patients with moderate-to-severe RA.Trial registrationClinicalTrials.gov identifier, NCT01711814.

Project description:OBJECTIVE:In disease-modifying antirheumatic drug-naive patients with early rheumatoid arthritis (RA) who had achieved sustained low disease activity (a Disease Activity Score in 28 joints using the erythrocyte sedimentation rate of ?3.2 at both week 40 and week 52) after 1 year of treatment with certolizumab pegol (CZP) at a standard dose (200 mg every 2 weeks plus optimized methotrexate [MTX]), we evaluated whether continuation of CZP treatment at a standard dose or at a reduced frequency (200 mg every 4 weeks plus MTX) was superior to stopping CZP (placebo plus MTX) in maintaining low disease activity for 1 additional year. METHODS:A total of 293 patients from period 1 of our study were re-randomized 2:3:2 in period 2 to CZP at a standard dose (n?=?84), CZP at a reduced frequency (n?=?127), or placebo plus MTX (CZP stopped) (n?=?82). The primary end point was the percentage of patients who maintained low disease activity throughout weeks 52-104 without flares. We used a hierarchical testing scheme, comparing CZP at a standard dose with CZP stopped. If P < 0.05 was achieved, then CZP at a reduced frequency was compared with CZP stopped (nonresponder imputation). RESULTS:The 293 patients from period 1 represented 36% fewer patients than projected, yielding a smaller number of patients eligible for period 2. Higher proportions of patients treated with the standard and reduced frequency regimens maintained low disease activity than those who had stopped CZP (48.8% and 53.2%, respectively, versus 39.2% [P?=?0.112 and P?=?0.041, respectively; nominal P value, first hierarchical test not significant]). Similar trends were observed for radiographic nonprogression (change from baseline of ?0.5 in modified Sharp/van der Heijde score; 79.2% and 77.9% of patients, respectively, versus 70.3%) and normative physical function (Health Assessment Questionnaire disability index score of ?0.5; 71.4% and 70.6% of patients, respectively, versus 57.0%). Safety profiles were similar between all groups, with no new safety signals identified for continuing CZP to week 104. No deaths were reported. CONCLUSION:The study failed to meet its primary end point. However, there were no clinically meaningful differences between the standard and reduced frequency doses of CZP plus MTX; both controlled RA more effectively than stopping CZP.
