Background and objectives: Rituximab (RTX) is one of the biologics available for rheumatologists to treat patients with rheumatoid arthritis (RA). While the reprocessing procedures for other biologic agents are clearly established, this is not the case for RTX. RTX is currently re-administered when clinical relapse occurs (6 to 18 months after initiation of treatment, beyond 24 months for some patients). However, this reprocessing method is not satisfactory because the resumption of symptomatology is generally detected too late. For patients, this delay can lead to increased doses of background and symptomatic treatments, an altered quality of life due to increased pain intensity, joint swelling, nocturnal awakening and morning stiffness and an aggravation of joint destruction. We hypothesize that tight monitoring by a nurse practitioner of RA patients in remission after treatment with RTX is more effective to detect very early relapse of the disease than follow-up exclusively managed by the attending rheumatologist.
Design: A prospective, controlled, randomized, open-label, bicentric clinical trial.
Methods: Eighty-eight patients with RA in remission receiving RTX treatment are randomly assigned to an observation group or a control group at a 1:1 ratio. In the control group, patients are followed only by the attending rheumatologist every 3 to 4 months according to common practices. In the observation group, patients are subjected to tight monitoring every month by a nurse practitioner in addition to follow-up by the attending rheumatologist. When increased disease activity is observed (disease activity score based on 28 joints (DAS28)-C-reactive protein (CRP) > 2.7), a new cycle of RTX is prescribed by an independent hospital practitioner.
Outcome measures: The primary outcome measure is the value of DAS28-CRP at the time of a new cycle of RTX. The secondary outcome measures are the cumulative dose of glucocorticosteroids and/or non-steroidal anti-inflammatory drugs between two cycles of RTX and quality of life questionnaires.
Discussion: This study corresponds to the combined management of RA by a nurse practitioner and an attending rheumatologist. A monthly telephone interview conducted by the nurse practitioner enables discussion on all aspects of the disease and regular follow-up to allow frequent readjustments. Thus, patients with good response to RTX treatment at 6 months might benefit from nursing follow-up alone to detect relapse. Such a practice is easily reproducible for RA patients in clinical remission after other treatments.
Ethics and dissemination: This trial was approved by the Northwestern France Ethics Committee (approval number: CPP-SC 02/2016) on June 1, 2016. The study protocol is conducted in accordance with the Declaration of Helsinki, formulated by the World Medical Association. Written informed consent is obtained from all participants. Subject recruitment is underway. Data collection began in May 2017 and will end in May 2021. Dissemination plans include presentations at scientific conferences and scientific publications.

| Introduction|| |
Rheumatoid arthritis (RA) is the most common form of chronic inflammatory rheumatism. RA mainly affects small- and medium-sized joints and causes progressive joint destruction with functional, psychological, social and occupational repercussions. Clinically, it results in pain, swelling and tender joints, morning stiffness, night awakenings and significant fatigue.
Rituximab (RTX) is one of the biologics available for rheumatologists to treat patients with RA. The schema of administration for RTX is not clearly established unlike other biologic agent. RTX differs from other biologics by a long interval between treatment cures because the selective depletion of CD20+ B cells by RTX results in a longer therapeutic response time. This singularity makes this drug one of the most complex to manage in routine. Indeed, although the European League against Rheumatism (EULAR) recommends evaluation of the therapeutic response from the 16th week, and a minimum interval of 6 months between two treatment cycles, it recommends carrying out new research to establish the optimal treatment strategy. RTX is currently re-administered when clinical relapse occurs (6 to 18 months after initiation of treatment, beyond 24 months for some patients). However, this reprocessing method is not satisfactory because the resumption of symptomatology is generally detected too late. For patients, this delay can lead to increased doses of background and symptomatic treatments (corticosteroids, analgesics and non-steroidal anti-inflammatory drugs (NSAIDs)), with proven potentially harmful side effects (cardiovascular, osteoporosis, etc.), an altered quality of life due to increased pain intensity, joint swelling, nocturnal awakening and morning stiffness, aggravation of joint destruction. The persistence of RA activity, even moderate, has been shown to be harmful in terms of joint destruction and functional capacity., Therefore, it is essential to identify resumption of RA activity before clinical relapse.
In particular, our team explored clinical and biological monitoring every 2 months to predict the resumption of disease activity by detecting the reemergence of CD19+ B lymphocytes. However, different approaches are possible to detect a new flare of RA leading to early retreatment. In this respect, the role of nurse practitioners might be relevant. Indeed, EULAR recommendations have highlighted the role of nurse practitioners in the assessment of chronic inflammatory rheumatism. The EULAR working group advocated that patients should have access to: education sessions, given by a nurse practitioner to improve their knowledge of their pathology and how to evaluate it; a nursing consultation and nursing telephone follow-up to improve continuity of care. Similarly, it specifies that nurse practitioner may: participate in disease activity monitoring to reduce symptoms and improve patient outcomes; promote patient self-assessment of the disease. Unlike other chronic conditions, RA cannot be assessed only on the basis of clinical or biological criteria. The latest EULAR recommendations are in favor of using a validated composite index, including joint count (number of painful and swollen joints), to assess RA activity in daily practice and guide treatment decisions. The American College of Rheumatology has published specific recommendations on the indexes to be used in current practice: disease activity score based on 28 joints (DAS28), validated by EULAR, is currently the most widely used criterion for evaluating RA activity in current practice and clinical trials. It is based on a complex mathematical formula, but easily usable at the bedside with pre-programmed calculators or digital applications. It takes into account: the number of painful joints out of a total of 28 joints (shoulders, elbows, wrists, metacarpophalangeal, proximal interphalangeal, knees); the number of swollen joints out of a total of 28 joints; the erythrocyte sedimentation rate (ESR) at the first hour or the C-reactive protein (CRP); self-assessment of overall disease activity by the patient rated between 0 and 100., Given that the values of the ESR can rise out of inflammatory context, the DAS28 was also developed using the CRP instead of the ESR. Several studies have shown a good correlation between DAS28-ESR and DAS28-CRP results.,,,
A classification of RA activity according to CRP levels has been proposed as follows: high activity if DAS28-CRP ≥ 4.1; moderate activity if DAS28-CRP > 2.7 and < 4.1; low activity if DAS28-CRP ≤ 2.7; remission if DAS28-CRP ≤ 2.3.
To demonstrate the efficiency of tight monitoring by a nurse practitioner of RA patients in remission receiving RTX treatment to detect very early relapse of the disease.
To demonstrate that tight monitoring by a nurse practitioner of RA patients, with good response to RTX, allows reduction in the number of prescriptions for corticosteroids and/or NSAIDs as a result of new flares of the disease, and an improvement in the quality of life of patients.
| Methods/Design|| |
This is a prospective, controlled, randomized, open-label, bicentric clinical trial. The inclusion period is 24 months. The maximum duration of participation per patient is 24 months. Number of visits per patient: the minimum number of visits expected per arm is 2. Since patients are followed up to clinical relapse, the number of follow-up visits varies among patients. The total research time is 48 months. The main findings are reported in [Table 1].
Department of Rheumatology, Rouen University Hospital and Department of Rheumatology, Caen University Hospital, France.
- Male or female patients (aged 18 years or older)
- Patients with RA fulfilling the American College of Rhumatology/European League Against Rheumatoid Arthritis criteria (ACR/EULAR 2010)
- Patients prescribed treatment with RTX or who received treatment with RTX in the last 6 months
- Patients with active RA prior to treatment with RTX (disease activity score based on 28 joints-C-reactive protein [DAS28-CRP] > 2.7)
- Patients with a DAS28-CRP of less than 2.7 at 6 months from the last administration of RTX
- Patients not responding to the last treatment with RTX (DAS28-CRP > 2.7 at 6 months)
- Patients under the age of 18 years
- Patients with chronic pain due to another pathology rather than RA, which may interfere with the assessment
- Patients with a contraindication to treatment with RTX
- Women of childbearing age not taking effective contraception
- Pregnant or lactating women
All patients who require treatment with RTX or who have been treated with RTX for less than 6 months receive an information note from the rheumatology departments of Rouen or Caen University Hospitals.
The patient signs a consent form beforehand. The following investigations are undertaken prior to review by the investigator:
- A clinical examination of the number of painful and swollen joints (out of 28)
- The latest biology analyses including complete bold count, ESR, CRP, aspartate aminotransferase and alanine aminotransferase
- An interview to collect the patient’s self-assessment of pain intensity, fatigue and disease activity (rated between 0 and 100), as well as the morning stiffness time and the number of night awakenings
- Calculation of the DAS28-CRP
- An interview to collect the names and dosages of background and symptomatic treatments (glucocorticosteroids, NSAIDs and analgesics) taken by the patient
- An interview to collect any side effect(s) attributable to RTX treatment
All these data allow the physician to evaluate the response to RTX.
In case RTX efficacy is not demonstrated by a decrease in RA activity (DAS28-CRP > 2.7), the rheumatologist may decide to refer the patient to day hospital for a new administration of RTX or to switch the biologic agent. In this case, the patient is not eligible for the study. In case RTX efficacy is demonstrated by a decrease in RA activity (DAS28-CRP < 2.7), follow-up visits are scheduled with the attending rheumatologist, every 3 to 4 months, until relapse of the disease; in this case, the patient is eligible for this study.
The randomization list by block has been established by the Biostatistics Unit of Rouen University Hospital using SAS 9.3 software (SAS Institute, Cary, NC, USA). This list is then centrally saved and readable by Ennov Clinical software (version 6.2, Ennov, Paris, France). Upon request, the investigator may obtain information on the arm to which the patient has been assigned. This information is sent by the system via e-mail to both the investigator of the center and the study sponsor. A document describing the randomization procedure is kept confidentially within the Biostatistics Unit. Randomization is planned the day the patient is included in the study.
The 88 patients who are expected for inclusion are randomly divided into two arms comprising 44 patients in each arm. Randomization is carried out to determine the monitoring mode attributed to the patients: either usual follow-up by the attending rheumatologist (arm 1: no intervention), or usual follow-up by the rheumatologist + tight nursing follow-up (arm 2: intervention group).
Patients randomized in arm 1 are examined by the attending rheumatologist every 3 to 4 months according to common practices. If the rheumatologist detects more active disease, the patient is referred within 15 days to a hospital practitioner independent from the study to confirm clinical relapse. If the relapse is confirmed (DAS28-CRP > 2.7), the patient receives a new cycle of rituximab.
In addition to the usual follow-up by their attending rheumatologist, patients in the intervention arm (arm 2) have:
- A training session with a nurse practitioner on self- assessing their RA: self-assessment of the number of painful and swollen joints, of pain and disease activity (global assessment by the patient) (self-DAS). During this session, ESR and CRP dosage are planned.
- A monthly telephone called by a nurse practitioner to collect the results of the patient’s self-assessment. If a relapse of RA is suspected, the nurse practitioner schedules a consultation to confirm the relapse or not. For this purpose, the nurse practitioner calculates the DAS28 taking into account the results of the biological tests, the articular count and the disease activity. Clinical relapse is defined as a DAS28-CRP > 2.7.
- A new cure of RTX prescribed by a hospital practitioner independent from the study.
The study is completed as soon as a hospital practitioner prescribes a new cycle of RTX [Figure 1] and [Figure 2].
Primary outcome measure
Value of DAS28-CRP at the time of a new cycle of RTX prescribed by a physician independent from the study.
Secondary outcome measures
- The cumulative dose of glucocorticosteroids and/or NSAIDs between two cycles of RTX
- The quality of life questionnaires: Health assessment questionnaire, The short form (36) Health Survery, and Short-form of the arthritis Impact Measurement Scales
Statistical analysis and sample size
Statistical analysis will be performed using SAS 9.3 software (SAS Institute). To assess the effectiveness of monthly telephone follow-up of patients, DAS 28 scores will be compared between intervention and non-intervention arms using two-sided non parametric Mann-Whitney U test. A P-value less than 0.05 will be considered statistically significant. In order to achieve 80% power with respect to a 30% difference between two arms, 44 patients will have to be included in each arm, hence 88 patients overall (nQuery 7.0, Statistical Solutions, Cork, Ireland).
Ethical considerations and informed consent
This trial follows the relevant laws and regulations of the Declaration of Helsinki and Quality Guidelines of the International Conference on Harmonisation (ICH).
This study has been approved by the Ethics Committee: the Northwestern France ethics committee (approval number: CPP-SC 02/2016) (Additional file 1 [Additional file 1]). The trial has been submitted to the Advisory Committee on Information Processing in Health Research and was declared to the National Commission on Information and Freedoms. Written informed consent will be obtained from each patient (Additional file 2 [Additional file 2]).
The results will be disseminated through national and international journals and conferences. The protocol adheres to the recommendations provided by the SPIRIT 2013 (Additional file 3 [Additional file 3]).
All information required by the protocol must be recorded in the (electronic) case report form and an explanation provided for all missing data. Data are collected as they are obtained. Erroneous data in the case report form are corrected by the investigator or the person authorized to make the correction. The traceability of modifications is automatic, via an audit-trail system. All the data are collected in an electronic case report form (quality of life questionnaires, number of painful and swollen joints, value of ESR and CRP, self-assessment of pain intensity, fatigue and disease activity, name and dosage of treatments taken by the patient).
Quality control of the clinical trial
The Clinical Research Associate, mandated by the sponsor, will visit each study center on a regular basis after the start of the clinical trial, during the trial according to the rhythm of inclusions and at the end of the trial. The Clinical Research Associate ensures that the rights and safety of the subjects are respected, that the data and information transmitted are reliable, of high quality and traceable, and that the study is conducted in accordance with the protocol, Guideline for Good Clinical Practice of ICH and the regulatory and legislative provisions in force.
The purpose of the visits will therefore be to verify and validate patient eligibility: compliance with inclusion and non-inclusion criteria; the adherence to patient information procedures , trial schedule, patient follow-up; quality of data collected in the case report form: accurate, complete and consistent.
At the end of each visit, a standardized monitoring report will be written by the Clinical Research Associate which will be reviewed by the promoter.
