BACKGROUND: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a peripheral nerve disorder characterised by weakness and sensory loss. We assessed the neonatal Fc receptor inhibitor rozanolixizumab for CIDP management. METHODS: CIDP01 (NCT03861481) was a randomised, subject-blind, investigator-blind, placebo-controlled, phase 2a study. Adults with definite or probable CIDP receiving subcutaneous or intravenous immunoglobulin maintenance therapy were randomised 1:1 to 12 once-weekly subcutaneous infusions of rozanolixizumab 10 mg/kg or placebo, stratified according to previous immunoglobulin administration route. Investigators administering treatment and assessing efficacy, and patients, were blinded. The primary outcome was a change from baseline (CFB) to day 85 in inflammatory Rasch-built Overall Disability Scale (iRODS) score. Eligible patients who completed CIDP01 entered the open-label extension CIDP04 (NCT04051944). RESULTS: In CIDP01, between 26 March 2019 and 31 March 2021, 34 patients were randomised to rozanolixizumab or placebo (17 (50%) each). No significant difference in CFB to day 85 in iRODS centile score was observed between rozanolixizumab (least squares mean 2.0 (SE 3.2)) and placebo (3.4 (2.6); difference -1.5 (90% CI -7.5 to 4.5)). Overall, 14 (82%) patients receiving rozanolixizumab and 13 (76%) receiving placebo experienced a treatment-emergent adverse event during the treatment period. Across CIDP01 and CIDP04, rozanolixizumab was well tolerated over up to 614 days; no clinically meaningful efficacy results were seen. No deaths occurred. CONCLUSIONS: Rozanolixizumab did not show efficacy in patients with CIDP in this study, although this could be due to a relatively high placebo stability rate. Rozanolixizumab was well tolerated over medium-to-long-term weekly use, with an acceptable safety profile.

OBJECTIVES: Smoking has been shown to influence rheumatoid arthritis (RA) severity and reduce response to some anti-tumour necrosis factor (anti-TNF) therapies. CIMDORA assessed the association between cigarette smoking and clinical effectiveness of certolizumab pegol (CZP) in Hungarian, Slovak, and Czech RA patients. METHODS: CIMDORA was a prospective, non-interventional, 104-week study (Feb 2011-Aug 2015). The primary endpoint was association between change in 28-joint Disease Activity Score (DAS28[ESR]) from baseline to Week 12, and baseline cigarette pack-year history. Secondary endpoints included association between change in DAS28(ESR) and daily number of cigarettes smoked. The full analysis set (FAS) included all patients receiving ≥1 dose of CZP with all necessary assessments for the primary endpoint. Treatment-emergent adverse events (TEAEs) were reported for all patients receiving ≥1 dose of CZP. RESULTS: The FAS included 218/273 enrolled patients: 155 Hungarian, 46 Czech and 17 Slovak. Hungarian and Czech patients completed 104 weeks (n=141); Slovak patients completed 52 weeks. Mean change in DAS28(ESR) [SD] at Week 12 (-2.78 [1.47]) was not significantly associated with baseline cigarette pack-year history (slope estimate [SE]: 0.03, 95% confidence interval [CI]: -0.16, 0.21 [p=0.77]). Mean DAS28(ESR) [SD] reductions to Week 52 (-3.33 [1.33]) were not significantly associated with daily number of cigarettes smoked in the previous month (SE: 0.001, CI: -0.05, 0.05 [p=0.95]). Two deaths were reported but neither of them was related to CZP. No new safety signals were identified and the safety profile was consistent with previous CZP studies. CONCLUSIONS: After 104 weeks of CZP treatment, patients demonstrated similar DAS28(ESR) improvements, irrespective of smoking history.

OBJECTIVE: Previous reports of RAPID-PsA (NCT01087788) demonstrated efficacy and safety of certolizumab pegol (CZP) over 24 weeks in patients with psoriatic arthritis (PsA), including patients with prior antitumour necrosis factor (TNF) therapy. We report efficacy and safety data from a 96-week data cut of RAPID-PsA. METHODS: RAPID-PsA was placebo-controlled to week 24, dose-blind to week 48 and open-label to week 216. We present efficacy data including American College of Rheumatology (ACR)/Psoriasis Area and Severity Index (PASI) responses, HAQ-DI, pain, minimal disease activity (MDA), modified total Sharp score (mTSS) and ACR responses in patients with/without prior anti-TNF exposure, in addition to safety data. RESULTS: Of 409 patients randomised, 273 received CZP from week 0. 54 (19.8%) CZP patients had prior anti-TNF exposure. Of patients randomised to CZP, 91% completed week 24, 87% week 48 and 80% week 96. ACR responses were maintained to week 96: 60% of patients achieved ACR20 at week 24, and 64% at week 96. Improvements were observed with both CZP dose regimens. ACR20 responses were similar in patients with (week 24: 59%; week 96: 63%) and without (week 24: 60%; week 96: 64%) prior anti-TNF exposure. Placebo patients switching to CZP displayed rapid clinical improvements, maintained to week 96. In patients with ≥3% baseline skin involvement (60.8% week 0 CZP patients), PASI responses were maintained to week 96. No progression of structural damage was observed over the 96-week period. In the Safety Set (n=393), adverse events occurred in 345 patients (87.8%) and serious adverse events in 67 (17.0%), including 6 fatal events. CONCLUSIONS: CZP efficacy was maintained to week 96 with both dose regimens and in patients with/without prior anti-TNF exposure. The safety profile was in line with that previously reported from RAPID-PsA, with no new safety signals observed with increased exposure. TRIAL REGISTRATION NUMBER: NCT01087788.
