Patient Satisfaction with CIMZIA^® (Certolizumab Pegol) AutoClicks^® in the UK.

ABSTRACT:

Introduction

The CIMZIA^® AutoClicks^® pre-filled pen (CZP PFP) was developed to overcome barriers to self-injection, by improving self-injection confidence, reducing fear associated with needle use, and supporting patients with impaired dexterity. The purpose of this research was to gather feedback on injection experience and the usefulness of training materials.

Methods

Eligible patients with rheumatoid arthritis (RA), axial spondyloarthritis (axSpA) or psoriatic arthritis (PsA) were at least 18 years of age and initiated onto the CZP PFP. Routine self-injection training and support were provided by trained specialist nurses. Patient experience (pain and skin reactions, confidence, satisfaction, and ease of use) was evaluated at visits 1-3 using an amended version of the self-injection assessment questionnaire (SIAQ) v2.0. Nurse and patient feedback on the training materials, and nurse opinions on patient self-injection after self-injection at visit 1, were also collected.

Results

Of 355 patients invited to participate, 196 provided informed consent and 79 participated in all three visits. Patients generally found the CZP PFP easy to use, and self-confidence and satisfaction were high. From visit 1 to visit 3, there was a numerical trend towards improvement in all three aspects of patient experience, most notably in both confidence and satisfaction. After self-injection at visit 1, confidence around safe patient self-injection was higher among nurses than among patients. Meanwhile, "pain and skin reactions" remained low at all visits. Patients thought the training materials contained sufficient information and were easy to understand and useful.

Conclusion

After training, patients generally found the device easy to use and showed high confidence and satisfaction with self-injection. Some patients may have been competent (based on nurse opinion), but initially lacked self-confidence. Increasing self-injection experience, together with patient training and continued support, may have facilitated high patient confidence and satisfaction, thereby potentially overcoming some of the barriers to self-injection.

Project description:Patient-reported outcomes (PROs) provide an opportunity to collect important information relating to patient well-being, which is often difficult for physicians to measure (e.g., quality of life, pain, fatigue, and sleep). Here we evaluate the effects of certolizumab pegol (CZP) on PROs during the 24-week, double-blind phase of the RAPID axial spondyloarthritis (SpA) trial, a phase 3 trial of axial SpA patients, including both ankylosing spondylitis (AS) and nonradiographic axial SpA patients.A total of 325 patients with active axial SpA were randomized 1:1:1 to placebo, CZP 200 mg every 2 weeks, or CZP 400 mg every 4 weeks. The primary end point was the Assessment of SpondyloArthritis International Society criteria for 20% improvement in disease activity response at week 12, and has been reported previously. PROs included total back pain, nocturnal back pain, a daily pain diary, the Sleep Problems Index II (SPI) domain of the Medical Outcomes Study (MOS) Sleep Scale, fatigue, the Ankylosing Spondylitis Quality of Life (ASQOL) measure, and the Short Form 36-item (SF-36) health survey physical component summary (PCS), mental component summary (MCS), and domains.Patients treated with CZP reported significant improvements from week 1 for nocturnal back pain (placebo -0.6, CZP 200 mg every 2 weeks -1.9, and CZP 400 mg every 4 weeks -1.6; P < 0.001) and ASQOL (placebo -1.0, CZP 200 mg every 2 weeks -2.3, and CZP 400 mg every 4 weeks -1.9; P < 0.05) compared with placebo, while significant improvements in total back pain were seen from day 2. Patients treated with both CZP dosing regimens also had significantly greater improvements in fatigue, MOS-SPI, SF-36 PCS, MCS, and domains compared with placebo. Improvements were similar in both AS and nonradiographic axial SpA patients.Both CZP dosing schedules rapidly improved patient well-being, as measured by PROs, including pain, fatigue, sleep, SF-36, and ASQOL in both AS and nonradiographic axial SpA patients.

Project description:BackgroundCrohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal tract, and immune response modulation is the main treatment strategy to induce remission in active CD. Certolizumab pegol (CZP) is a tumor necrosis factor-alfa (TNF-α) inhibitor which regulates impaired immune response.ObjectivesThe primary objectives were to evaluate the efficacy and safety of CZP for the induction of remission in CD.Search methodsWe searched MEDLINE, Embase, CENTRAL, the Cochrane IBD group specialized register, trials registers and other sources from inception to 28 January 2019. Moreover, we contacted the pharmaceutical company that manufactures CZP.Selection criteriaWe included randomized controlled trials comparing CZP with placebo or no treatment in active CD patients.Data collection and analysisWe used standard Cochrane methodological procedures. The main outcomes selected for GRADE analysis were clinical remission at week 8 (Crohn's Disease Activity Index [CDAI] ≤150), clinical response at week 8 (CDAI reduction ≥ 100 or clinical remission), and serious adverse events. The Mantel-Haenszel random-effects method was applied for the statistical analyses. For dichotomous outcomes, we calculated the risk ratio (RR) and corresponding 95% confidence interval (95% CI).Main resultsFour studies involving 1485 participants with moderate to severe CD met the inclusion criteria and were used in the meta-analyses. All studies included active CD patients with CDAI ranging from 220 to 450. Most patients were adults over 18 years of age. One study was identified as high risk of bias due to a non-identical placebo while the other studies were judged to be at low risk of bias.CZP (100 mg to 400 mg every 2 to 4 weeks) was shown to be superior to placebo for achieving clinical remission at week 8 (RR 1.36, 95% CI 1.11 to 1.66; moderate certainty evidence). The raw numbers of participants achieving clinical remission at week 8 were 26.9% (225/835) and 19.8% (129/650) in the CZP and the placebo groups, respectively.CZP was shown to be superior to placebo for achieving clinical response at week 8 (RR 1.29, 95% CI 1.09 to 1.53; moderate certainty evidence). In raw numbers, clinical response at week 8 was achieved in 40.2% (336/835) and 30.9% (201/650) of participants in the CZP and the placebo groups, respectively.In raw numbers, serious adverse events were observed in 8.7% (73/835) and 6.2% (40/650) of participants in the CZP and the placebo groups, respectively (RR 1.35, 95% CI 0.93 to 1.97; moderate certainty evidence). Serious adverse events included worsening Crohn's disease, infections, and malignancy.Authors' conclusionsModerate certainty evidence suggests that CZP is effective for induction of clinical remission and clinical response in participants with active CD patients. It is uncertain whether the risk of serious adverse events differs between CZP and placebo as the 95% CI includes the possibility of a small decrease or doubling of events. Future studies are needed to evaluate the long-term efficacy and safety of CZP in CD patients.

Project description:BackgroundBiologicals directed against tumour necrosis factor (TNF) have proven their efficacy in the treatment of spondyloarthritis and rheumatoid arthritis. We present a radiolabelling method for certolizumab pegol (CZP), a commercially available humanized Fab'-fragment directed against TNF. A biodistribution and dosimetry study was conducted. Tc-S-HYNIC CZP was synthesized. The in vitro TNF neutralizing activity was tested by exposing L929s-cells to various concentrations 99mTc-S-HYNIC CZP and measuring TNF-induced cytotoxicity. For biodistribution and dosimetry, WB images and blood and urine sampling were performed up to 24 h pi. Cumulative activities were estimated using mono-exponential fitting, and organ doses were estimated using OLINDA/EXM. The effective dose was calculated using the International Commission on Radiological Protection 103 recommendations. The uptake of the tracer in the peripheral joints was assessed visually and semiquantitatively.ResultsIn vitro tests showed blocking of TNF cytotoxicity by the 99mTc-S-HYNIC CZP formulation comparable to the effect obtained with the unlabelled CZP with or without the HYNIC linker. We analysed eight patients with rheumatoid arthritis or spondyloarthritis. The highest mean absorbed organ doses were recorded for kidneys, spleen, and liver: 56 (SD 7), 34 (SD 6), and 33 (SD 7) μGy/MBq. The effective dose was 6.1 (SD 0.9) mSv for a mean injected activity of 690 (SD 35) MBq. The urinary excretion was 15.1% (SD 8.1) of the IA at 22.5 h. Blood analysis yielded a distribution half-life of 1.2 h (SD 1.5) and an elimination half-life of 26.9 h (SD 2.7). Visual analysis of the scans revealed marked tracer accumulation in the clinically affected peripheral joints. In addition, there was a statistically significant higher uptake of the tracer in the swollen joints (median uptake ratio compared to background of 3.3 in rheumatoid arthritis and 2.4 in peripheral spondyloarthritis) compared to clinically negative joints (respectively 1.3 and 1.6).ConclusionsWe present a radiolabelling technique for CZP, a Fab'-fragment directed against TNF and currently used as a therapeutic agent in rheumatology. An effective dose of 6.1 mSv (SD 0.9) was estimated. We confirmed the uptake of this new radiopharmaceutical in clinically affected peripheral joints.
